Current concepts in the management of childhood myopia
Authors: Dhiman Rebika , Rakheja Vaishali , Gupta Vinay , Saxena Rohit
Published: August 2022

Myopia or short-sightedness is an emerging pandemic affecting more than 50% population in South-Asian countries. It is associated with several sight-threatening complications, such as retinal detachment and choroidal neovascularization, leading to an increased burden of visual impairment and blindness. The pathophysiology of myopia involves a complex interplay of numerous environmental and genetic factors leading to progressive axial elongation. Environmental factors such as decreased outdoor activity, reduced exposure to ambient light, strenuous near work, and role of family history of myopia have been implicated with increased prevalence of this refractive error. While multiple clinical trials have been undertaken to devise appropriate treatment strategies and target the modifiable risk factors, there is no single treatment modality with ideal results; therefore, formulating a comprehensive approach is required to control the myopia epidemic. This review article summarizes the epidemiology, dynamic concepts of pathophysiology, and evolution of the treatment modalities for myopia such as pharmacological (atropine and other agents) and optical methods (spectacles, contact lenses, and orthokeratology).

Authors: Singh Prem Kumar , Sharma Preeti , Sharma Sonia , Ganesh Suma
Published: August 2022

Purpose:

To analyze the efficacy of fusional vergence therapy (FVT) in management of consecutive esotropia with diplopia after intermittent exotropia (IXT) surgery. The current study is carried on how FVT affects the duration of treatment, sensory fusion, and exotropic drift.

Methods:

This was a retrospective study for the medical record of 11 patients with consecutive esotropia after IXT surgery of 543 patients over the period of 5 year, with mean surgery age of 9.5 (range: 4–33 y). FVT was planned after minimum 6 weeks of surgery and was considered for maximum 24 weeks. Patients underwent a combination of office-based and home-based FVT. Successful outcome of therapy was considered where diplopia resolves in free space and achieves sensory fusion, stereopsis with no manifest deviation.

Results:

Record of 543 patients who had horizontal muscle surgery for IXT were identified and reviewed. Records of 11 patients who showed consecutive esotropia of 10 prism diopter (PD) or more with normal retinal correspondence, with or without diplopia complaint, after 6 week of surgery and had undergone vision therapy management were reviewed. A successful outcome of binocular single vision with good sensory and motor fusion with no manifest deviation or prism requirement was achieved with in the mean duration of 4.8 month of therapy. With a mean duration of 4 weeks of therapy, the mean angle of deviation reduced by 53% for distance (17 PD to 8 PD) and 27% for near (11 PD to 8 PD) and mean stereopsis improvement by 80% with 94% patients demonstrating sensory fusion on Bagolini test and 94% of patients having no symptoms of diplopia or squint.

Conclusion:

With nonsurgical management involving refractive error correction, FVT, and prism, consecutive esotropia was resolved in 74% cases. Management of consecutive esotropia with FVT can result in satisfactory sensory fusion and successful motor alignment.

Authors: Parikh Rajul , Sachdeva Virender , Kekunnaya Ramesh , Rao B Venkateshwar , Parikh Shefali , Thomas Ravi
Published: August 2022

Purpose:

To report retinal nerve fiber layer thickness (RNFLT) in eyes with amblyopia compared with contralateral healthy eyes.

Methods:

In this cross-sectional study, we included patients with anisometropic amblyopia, strabismic amblyopia, and mixed amblyopia. All subjects underwent complete ophthalmic examination, including RNFLT measurement with time-domain OCT (Stratus OCT) and scanning laser polarimeter (GDX VCC). A paired “t” test was used to compare average and quadrant-wise RNFL thickness between the amblyopic and contralateral normal eyes. In addition, an analysis of variance test was used to compare various RNFL thickness parameters between the three groups.

Results:

A total of 33 eyes of 33 subjects with anisometropic amblyopia, 20 eyes of 20 subjects with strabismic amblyopia, and 38 eyes of 38 subjects with mixed amblyopia were included. In the anisometropic amblyopia group, the average RNFLT in the amblyopic eye was 98.2 mm and 99.8 mm in the fellow normal eye (P = 0.5), the total foveal thickness was 152.82 mm (26.78) in the anisometropic eye and 150.42 mm (23.84) in the fellow eye (P = 0.38). The difference between amblyopic and contralateral normal eye for RNFL and macular parameters was statistically insignificant in all three groups. The RNFL thickness in four quadrants was similar in the amblyopic and non-amblyopic eye between all three groups and statistically non-significant.

Conclusion:

Our study showed that RNFL thickness was similar in amblyopic and non-amblyopic eyes between all three amblyopia groups.

Published: August 2022

Purpose:

To describe the etiology, clinical profile, duration of lagophthalmos cases and thereby, framing a decision for the management based on the severity of Exposure keratitis (EK), Facial palsy (FP) with each etiology and to describe the outcome of the management options.

Methods:

The method was a prospective review of 120 lagophthalmos cases treated at a single tertiary center from January 2018 to January 2019. The main outcome measures were analysing the association between age, etiology, duration and management of lagophthalmos.

Results:

Of the 120 patients studied, paralytic etiology was noted in 86 and eyelid etiology in 34 patients. The percentage of various lagophthalmos etiology documented were Bell’s palsy (35.83%), lagophthalmos in ICU patients (15%), traumatic facial palsy(FP) (10.80%), stroke associated FP (6.67%), infection associated FP (6.67%), iatrogenic FP, cicatricial lagophthalmos (5%), lagophthalmos post eyelid surgeries (5%), neoplastic FP(3.33%), congenital FP (1.67%), proptosis induced lagophthalmos (1.67%), floppy eyelid syndrome induced lagophthalmos (0.83%) and lid coloboma associated lagophthalmos (0.83%). A statistically significant correlation was noted between exposure keratitis and age, with an increased prevalence age advances. The management showed significant variation with individual etiology, with some etiologies unquestionably requiring surgical management. Surgical management is crucial as the duration of lagophthalmos increases more than 6 weeks, EK involving pupillary axis and poor FP recovery.

Conclusion:

This study concludes that the conservative management was sufficient in all cases when the duration is less than 1 week, Exposure keratitis not involving the pupillary axis (EK< Grade II) and FP with good functional recovery ( FP < Grade III). The predominant causes being Bell’s palsy, lagophthalmos in ICU patients and vascular FP. Whereas, cases with poor functional recovery of facial palsy(FP) and permanent eyelid deformation require definitive surgical management like Traumatic FP & cicatricial lagophthalmos.

Published: August 2022

Purpose:

To describe the increase in prevalence of ethambutol-induced optic neuropathy (EON) in patients presenting to a single tertiary referral eye care center in India after introduction of weight-based fixed dose combinations and an increase in duration of ethambutol use from 2016 in the Revised National Tuberculosis Control Program.

Methods:

This was a retrospective, observational, referral hospital-based study of 156 patients with a diagnosis of EON presenting to a single tertiary referral eye care center between January 2016 and December 2019. The main outcome measure was to assess the increase in prevalence of EON cases presenting to our tertiary care institute.

Results:

During the 4-year study period, 156 new patients were diagnosed with EON. A total of 101 patients (64.7%) were males and 55 (35.3%) were females. The most common age group affected was 41–60 years. The significant complaint at presentation was decreased vision in all the patients. A rising trend in the number of patients diagnosed as EON was seen, with the prevalence increasing from 16 cases in 2016, 13 cases in 2017, and 31 cases in 2018 to 96 cases in 2019.

Conclusion:

The results of this study indicated an alarming increase in the trend of EON cases presenting to our tertiary care institute.
Morphological characterization of subretinal hyper-reflective material in posterior uveitis using swept-source optical coherence tomography and optical coherence tomography angiography
Authors: Arora Atul , Agarwal Aniruddha , Bansal Reema , Katoch Deeksha , Dogra Mohit , Sharma Aman , Agrawal Rupesh , Gupta Vishali
Published: August 2022

Purpose:

To analyze the structural features of subretinal hyper-reflective material (SHRM) in posterior uveitis using swept-source optical coherence tomography (SS-OCT) and optical coherence tomography angiography (SS-OCTA).

Methods:

In this observational study, subjects with quiescent posterior uveitis and the presence of SHRM on SS-OCT were subjected to SS-OCTA to identify the presence of an intrinsic choroidal neovascular (CNV) network. OCT features were compared for SHRM harboring CNV (vascular SHRM) with those without CNV network (avascular SHRM) to identify clinical signs pointing toward the presence of CNVM inside SHRM.

Results:

Forty-two eyes of 33 subjects (18 males; mean age: 29.52 ± 12.56 years) were evaluated. Two-thirds (28/42) of eyes having SHRM on SS-OCT harbored intrinsic neovascular network (vascular SHRM). Increased reflectivity of SHRM (P < 0.001) and increased transmission of OCT signal underlying SHRM (P = 0.03) were suggestive of the absence of CNVM. The presence of intra/subretinal fluid (P = 0.08) and pitchfork sign (P = 0.017) were important markers of vascular SHRM.

Conclusion:

SHRM is an important OCT finding in eyes with posterior uveitis. Meticulous assessment of SHRM characteristics on SS-OCT can aid in identifying the underlying intrinsic neovascular network.
Vertical transposition of the horizontal rectus muscles to correct head tilt because of infantile nystagmus syndrome – A case series
Authors: Kekunnaya Ramesh , Jain Mayank
Published: August 2022

Purpose:

Head tilt associated with infantile nystagmus syndrome (INS) can be corrected by (a) operating the oblique muscles, (b) horizontally transposing the vertical rectus muscles, or (c) vertically transposing the horizontal rectus muscles. We report three cases of INS with head tilt corrected by vertically transposing the horizontal rectus muscles in both the eyes.

Methods:

Three cases of head tilt with INS from an institutional practice operated by a single surgeon were retrospectively reviewed and analyzed. The intervention included full tendon width transposition (upward or downward) of all four horizontal rectus muscles to induce cyclotorsion in the direction of head tilt. The primary outcome measure was the correction of head tilt in the primary position.

Results:

Three patients (boys) of ages ranging from 4 to 7 years with a pre-operative head tilt of 30° were operated upon. Although one patient’s oblique muscles had been operated on to correct head tilt, another patient had an unmasked face turn after the surgery, which was corrected with a modified Anderson’s procedure. Post-operatively, all patients had a reduction of head tilt to a range of 0–10°.

Conclusion:

Vertical transposition of horizontal rectus muscles is a simple surgical option to correct head tilt in INS. However, the results may vary based on individual cases.
Profile of infantile strabismus at a tertiary eye care center in India
Authors: Doctor Mariya Bashir , Sachadeva Virender , Kekunnaya Ramesh
Published: August 2022

Purpose:

To study the profile, risk factors, and management outcomes of infantile strabismus at a tertiary eye care center.

Methods:

We prospectively analyzed the data of infants (children less than 1 year of age) who presented at our institute from August 2018 to December 2019. We excluded infants who did not complete a minimum follow-up of 6 months. Detailed meticulous history based on a set of standardized questionnaires was obtained and a comprehensive ophthalmological examination of the child was performed. Data were collected regarding refractive error (astigmatism; myopia; hyperopia; anisometropia [<1.0 DS or >1.0 DS]; astigmatism [<1.0 DS or >1.0 DS]) and the type of strabismus.

Results:

During this period, we saw 4,773 infants, out of which 123 infants were diagnosed to have infantile-onset strabismus (hospital prevalence of 2.6%). Boys and girls were equally affected. Sixty-two patients had esotropia, 37 had exotropia, 2 had hypotropia, and 22 had pseudo strabismus. Prematurity, hypermetropia, and anisometropia had increased odds of developing esotropia, whereas delivery by cesarean section, delayed cry at birth, infantile seizures, parental consanguinity, delayed development of milestones, and myopia had increased odds of developing exotropia. Twenty-nine patients underwent a surgical correction. The mean deviation at the first visit was 42.59 ± 15.40 PD and 8.25 ± 12.70 PD at the last visit. For all patients who underwent a squint surgery, the change in ocular deviation was clinically and statistically significant (P-value <0.0001, paired t-test).

Conclusion:

The hospital prevalence of infantile strabismus in our cohort was found to be 2.6%. Our study suggests that esotropia is two-fold more common in our cohort as compared to exotropia. Further, our study highlights risk factors for the development of strabismus in infancy, which must be kept in mind and awareness must be created among pediatricians. Surgical correction should be considered early during the infantile period, because it may lead to promote the development of good binocular vision.

Authors: Balıkçı Ayşe Tüfekçi , Ulutaş Hafize Gökben , Özgen Gülten Aslan
Published: August 2022

Purpose:

To compare findings in specular microscopy, corneal topography, and noncontact meibography in polycystic ovary syndrome (PCOS) patients with healthy controls.

Methods:

A total of 40 women with PCOS and 32 healthy controls were enrolled in the study. Schirmer’s test, Ocular Surface Disease Index (OSDI), noninvasive tear break-up time (NITBUT), the mean keratometry (Km), maximum keratometry (Kmax), central (CCT), thinnest (TCT) and apical (ACT) corneal thicknesses, meibomian gland (MG) loss, meiboscores, morphology of MGs, endothelial cell density (ECD), coefficient of variation (CV), and percentage of hexagonal cells (PHEX) were analyzed. Correlations between anti-Mullerian hormone (AMH) and sex hormones and the findings of PCOS patients were evaluated.

Results:

Mean OSDI score, intraocular pressure, Km and Kmax values, the mean MG loss of upper and lower eyelids, lower eyelid meiboscore, and degree of morphological abnormalities of MGs were higher in cases with PCOS than healthy controls. There were no significant differences between groups in Schirmer results, first and average NITBUT, mean values of TCT, ACT, CCT, ECD, CV, and PHEX (P > 0.05, for all). There were correlations between plasma AMH level and Kmax, back Km and PHEX, and between estradiol (E2) and PHEX; there were negative correlations between E2 and total MG loss and CV and between total testosterone and ACT.

Conclusion:

Loss and morphological deterioration of the MGs are observed in PCOS patients, even if the tear parameters are not impaired yet. In eyes with PCOS, keratometry values become steeper in proportion to AMH levels. The PCOS patients should be followed carefully for the development of corneal ectasia.

Mapping the thickness of retinal layers using Spectralis spectral domain optical coherence tomography in Indian eyes
Authors: Najeeb Shaista , Ganne Pratyusha , Damagatla Manikanta , Chaitanya Ganne , Krishnappa Nagesha C
Published: August 2022

Purpose:

This study aimed at establishing the normative data for the thickness of macular layers on Spectralis Spectral-domain optical coherence tomography (SD-OCT) in healthy Indian eyes and testing the effects of age, gender, central corneal thickness (CCT), and intraocular pressure (IOP) on such values.

Methods:

This cross-sectional study was done on 308 eyes of 159 healthy subjects. OCT scans were obtained using the posterior pole asymmetry scan protocol. From the thickness map, data were grouped into nine Early Treatment Diabetic Retinopathy Study (ETDRS) macular sectors. Correlation between retinal thickness and age/IOP/CCT was done using Pearson correlation. Correcting for age as a covariate, multivariate regression analysis was done to know which retinal layers showed significant differences in thickness between males and females.

Results:

The mean age was 46.06 ± 13.06 years (range: 20–75 years). Significant central subfield (CSF) thickening with age was noted in retinal nerve fiber layer (RNFL), inner nuclear layer (IPL), inner nuclear layer (INL), outer plexiform layer (OPL), and outer nuclear layer (ONL) (P < 0.04). The average thickness of the outer ring reduced with age in the ganglion cell layer (GCL)/IPL/INL (P = 0.001). Women had thinner inner and outer retinal thickness than men in all ETDRS rings (P < 0.001). There was no interocular asymmetry (P > 0.05) and no correlation between IOP/CCT and retinal layer thickness.

Conclusion:

In CSF, age-related thickening was noted in RNFL, IPL, INL, OPL, and ONL. The average inner ring thickness decreased with age in GCL and IPL and increased in the RPE layer. The average outer ring thickness decreased with age in GCL, IPL, and INL layers and increased in OPL. The average IR and OR thickness was significantly less in women compared to men in all sub-fields. There was no correlation between IOP/CCT and retinal layer thickness.
A Retrospective Study of Risk Factors of Stroke or Pathological Transcranial Doppler Ultrasonography in Children with Sickle Cell Disease in Jeddah, Saudi Arabia
Authors: Al-Harbi Ibrahim , Algiraigri Ali , Khaldi Sumaya , Albogmi Rahf , Asiri Salha , Alogaibi Wed
Published: August 2022

INTRODUCTION:

Sickle cell disease (SCD) is an autosomal recessive disorder characterized by hemolytic anemia with abnormal red blood cells. Stroke is a devastating complication of SCD. In Saudi Arabia, there is a high incidence of children with SCD who have had stroke. No studies have been conducted to look at the risk factors. In this review, we aim to explore these risk factors.

METHODOLOGY:

In this retrospective cohort, individuals between 0 and 18 years old, diagnosed with SCD and had either a stroke, or pathological transcranial Doppler ultrasonography (TCD) result (cerebral blood velocity ≥200 cm/second or repeated borderline result >170 cm/second) were included. 38 cases were assessed. The parents were interviewed regarding patients personal, social, and family history. Medical and laboratory data were obtained from medical records.

RESULTS:

Females were more affected (20/38). Most children are of an average socioeconomic status (20/38 compared to only 12/38 with poor socioeconomic status). Parental education inversely correlated with the risk of stroke/pathological TCD. The most common presentation of stroke was weakness (9/38), followed by headache (5/38). History of a prior stroke was found to be significant at 15.8%. The Cooperative Study of SCD found that leukocytosis is associated with an increased risk of stroke. In contrary, our review showed an average white blood cell count of 13.01 (+/[FIGURE DASH]5.36), HbS concentration at the onset of stroke, and/or pathological TCD of 66.23% (+/[FIGURE DASH]20.11). The most common artery involved was the middle cerebral artery.

CONCLUSION:

Stroke is very prevalent in children with SCD in Saudi Arabia. A striking finding was that parental education inversely correlated with the risk; therefore, improving the awareness level of SCD among parents is crucial. Wide implementation of TCD as a screening tool and improving compliance with TCD may lead to reduce the risk. We encourage Saudi researchers to focus on central nervous system complications in children with SCD.

everal mathematical concepts remain unchanged for centuries, many were never even considered to be expanded upon. Typical cases, such as the ratios of geometric and arithmetic progressions, for example, which until now humanity uses with a singular, unique and fixed value. The search for new elements, new formulas, expansion of concepts such as accelerations and other magnitudes belonging to the field of kinematics, were motivating factors for the Brazilian researcher who created the Infinite Series with Multiple Ratios (SRMs), with whom the author of this article had the honor to work and help in the creation of these new magnitudes of the exact sciences with countless applications. SRMs remain unknown to humanity to this day, even though more than 23 years have passed since the first presentations and publication in a Brazilian technical magazine. The passion for low-level computing made the author of this article see that SRMs have infinite applicability in machine language, data compression, data lookup and cryptography. This article presents a cryptographic method made with these mathematical elements totally unknown to humanity and with surprising results that will be reported here.

El politereftalato de etileno (PET) es un termoplástico de la familia de los poliéster no biodegradables, uno de los mejores métodos para la recuperación de residuos de polímeros es el reciclaje químico. El objetivo del presente estudio fue el reciclaje químico del PET a través de glucólisis catalizada para la obtención de Bis-2-hidroxietil-tereftalato (BHET), evaluando la acción catalítica de sustancias como Acetato de Zinc, Carbonato de Sodio y Óxido de Zinc, en condiciones de presión atmosférica, temperatura de 180-190°C, tiempo de dos horas y relación PET/EG de 1:3. La reacción se llevó a cabo en un reactor de vidrio adaptado con un balón de dos bocas obteniéndose un fino polvo blanco con rendimientos de 85.16, 82.06 y 80.69% para cada sustancia respectivamente. Los productos se analizaron por espectroscopía infrarroja demostrando la existencia de grupos funcionales característicos del BHET, además se identificó que la reacción con acetato de zinc presentó el mejor rendimiento, con un valor de 85,16%, ya que la sustancia posee el metal más activo. Mediante la glucólisis de PET se obtendrá BHET que se utiliza en la fabricación de productos como espumas de poliuretano, hormigón polimérico, resinas de poliéster dando una alternativa de reciclaje mejorada a dicho material.

Authors: Mohini  , Ahmed Sakir
Published: August 2022

Peer review is an integral part of an ethical scientific publication process. Though not perfect, it has not been replaceable in the last couple of centuries since the advent of scientific journals. Recent innovations include online anonymized credits for peer review that can be used to augment an academician’s resume. Submissions and retraction are ever growing, increasing the demands from peer reviewers. The rewards may not seem commensurate but any person of science should contribute to peer review as a guardian of science. This short review looks at the ideal peer review along with inherent challenges. It makes suggestions on how novice and intermediate reviewers can improve their contributions as well as introduces various resources relevant for peer review.

THE BLARING SILENCE
Predição e espacialização de elementos potencialmente tóxicos em solos no entorno de pilha de rejeitos de mineração: riscos à saúde humana e fitorremediação
Authors:   , Paes Ésio de Castro
Published: August 2022

A atividade de mineração é muito importante para o crescimento de um País, porém a mesma gera uma grande quantidade de rejeitos, que, quando dispostos de maneira inadequada podem se dispersar no meio ambiente, aumentando os níveis de elementos potencialmente tóxicos (PTEs) nos solos. Assim, determinar os níveis e a distribuição espacial dos PTEs é essencial para traçar estratégias mitigadoras e remediar áreas contaminadas. Dessa forma, o objetivo desse estudo foi avaliar os níveis e a extensão da contaminação de elementos potencialmente tóxicos nos solos próximos a pilha de rejeito de mineração, bem como avaliar o potencial risco à saúde da população (Capítulo 1), desenvolver metodologia rápida e eficiente para monitorar os níveis de contaminantes em áreas impactadas pela atividade de mineração (Capitulo 2) e identificar espécies vegetais capazes de remediar áreas contaminadas (Capítulo 3). O estudo foi desenvolvido no Município de Boquira-Ba, no qual foram coletadas 120 amostras compostas de solos em uma malha regular, na profundidade de 0-10 cm. Os resultados demonstraram que os uso de algoritmos de aprendizagem de maquinas é uma alternativa eficiente para espacializar áreas contaminadas pela atividade de mineração, onde predomina fontes difusas de contaminantes. Observou-se também que as áreas próximas as pilhas de rejeito se encontram altamente contaminadas podendo ser prejudicial ao meio ambiente e a saúde humana. No segundo capítulo foi desenvolvida uma estrutura metodológica para monitorar áreas contaminadas com PTEs, por meio do uso de algoritmos de aprendizagem de máquinas. Os resultados demonstraram que o uso de covariáveis como as concentrações totais dos elementos, medidas por fluorescência de raio-X (XRF), texturais e morfométricas são úteis para prever os teores de PTEs nos solos. Por fim, foi possível observar que as espécies vegetais P. juliflora, A. peregrina toleram altas concentrações de Pb nos solos, e são capazes de estabilizar esse metal no sistema radicular. As demais espécies M. oleífera e U. ruziziensis também cresceram nos solos contaminados, porém ocorreram reduções nos valores dos parâmetros de crescimentos. Palavras-chave: Áreas contaminadas.
