title: Congenital and developmental cataract: axial length and keratometry study in Brazilian children

description: ABSTRACT Purpose: To evaluate the ocular axial length (AL) and keratometry (K) in Brazilian children with congenital/developmental cataract, assess the differences and evolution of AL and K according to age, and establish functional models of AL and K as function of age. Methods: Children with congenital/developmental cataract aged 1.5 months old to 8 years old and no other ocular diseases were included. All eyes with unilateral cataract, the left eyes from children with bilateral cataracts, and healthy eyes from children with unilateral cataract were analyzed. After the administration of anesthesia, K was measured with a portable automatic keratometer, and AL was measured with a contact biometer. Cataract surgery was performed immediately after the measurements were taken. The data were statistically analyzed, and a linear regression with an age logarithm was used to model the relationship. Results: Forty-four eyes with cataract were included in this analysis, comprising 15 eyes with unilateral cataract and 29 left eyes from children with bilateral cataracts. The mean age was 27.3 months with a mean AL of 20.63 ± 2.11 mm and a mean K of 44.94 ± 2.44 D. The K value was significantly steeper and the AL value was significantly shorter in younger children (P&lt; 0.001). No significant differences were found neither between eyes with unilateral and bilateral cataracts nor between eyes with unilateral cataract and their corresponding healthy eyes (P &gt;0.05). Conclusion: The values of K and AL significantly change with age, especially during the first 6 months of life. A linear functional relationship between K and AL with the logarithm of age and between K and AL was established.

title: TREATMENT OF SPORT INJURIES WITH ACUPUNCTURE: A LITERATURE REVIEW

description: ABSTRACT As acupuncture is growing in popularity in Brazil and worldwide, it is necessary to study the benefits and possibilities of this type of treatment more in depth, especially as it is believed to produce fast results with few side effects and does not involve substances banned in sports. Thus, it seems like a good option to be considered as main or adjuvant therapy in sports-related injuries. In order to gain more knowledge about this subject, this article is an integrative review analyzing the publications of the period between January 2012 and January 2017 on the Cochrane and Pubmed platforms that analyzed acupuncture in the treatment of sports injuries. We found 49 articles, 11 of which fulfilled the inclusion criteria: two case reports, three clinical trials and six literature reviews. Although all the articles analyzed produced favorable results with the use of the therapeutic technique in question, flaws in the designs of the studies and the difficulty of creating a placebo control group in acupuncture hinder the qualification of the articles on evidence rating scales. Therefore, it is suggested to the researchers that further studies be published with experimental animal models and observational studies, and that STRICTA recommendations be followed to improve the level of evidence of acupuncture research. Level of Evidence II; Systematic review of level II studies.

title: The Importance of Identifying Learning Styles in Medical Education

description: ABSTRACT Learning is a complex construct that involves several factors, mainly the interaction between teachers and students in the process of teaching and learning. Understanding how students learn and which factors influence academic performance is essential information for lesson planning and evaluation, in addition to allowing a better use of students’ learning potential and outcomes. The ability to constructively modify one’s behavior depends on how well we combine our experiences, reflections, conceptualizations, and planning to make improvements. This seems particularly relevant in medical education, where students are expected to retain, recall, and apply vast amounts of information assimilated throughout their training period. Over the years, there has being a gradual shift in medical education from a passive learning approach to an active learning approach. To support the learning environment, educators need to be aware of the different learning styles of their students to effectively tailor instructional strategies and methods to cater to students’ learning needs. However, the space for reflection on the process of teaching is still incipient in higher-education institutions in Brazil. The present article proposes a critical review of the importance of identifying students’ learning styles in undergraduate medical education. Different models exist for assessing learning styles. Different styles can coexist in equilibrium (multimodal style) or predominate (unimodal style) in the same individual. Assessing students’ learning styles can be a useful tool in education, once it is possible to analyze with what kind of learning students can better develop themselves, improving their knowledge and influencing positively in the process of learning. Over the last century, medical education experienced challenges to improve the learning process and curricular reform. Also, this has resulted in crucial changes in the field of medical education, with a shift from a teacher centered and subject based teaching to the use of interactive, problem based, student centered learning.

title: Comparison of pain scores between patients undergoing panretinal photocoagulation using navigated or pattern scan laser systems

description: ABSTRACT Purpose: To compare the pain responses of patients with proliferative diabetic retinopathy (PDR) undergoing panretinal photocoagulation (PRP) using either pattern scan laser (PASCAL) or navigated laser photocoagulation (NAVILAS). Methods: Patients diagnosed with PDR were randomly assigned to undergo either PASCAL or NAVILAS photocoagulation treatment. PRP was performed using the multi-shot mode with a spot size of 200-400 µm and a pulse duration of 30 ms to obtain a white-grayish spot on the retina. Parameters were identical in both procedures. After 30 min of PRP application, patients were asked to verbally describe their pain perception as either "none," "mild," "moderate," "severe," or "very severe" using a verbal rating scale (VRS) and visual analog scale (VAS) by indicating a score from "0" to "10," representing the severity of pain from "no pain" to "severe pain." Results: A total of 60 eyes of 60 patients (20 females and 40 males) diagnosed with PDR were treated. The mean age of patients was 62.22 ± 9.19 years, and the mean diabetes duration was 195.47 ± 94.54 months. The mean number of laser spots delivered during PRP was 389.47 ± 71.52 in the NAVILAS group and 392.70 ± 54.33 in the PASCAL group (p=0.57). The difference in pain responses between patients in the NAVILAS and PASCAL groups was significant with regard to the mean VRS (1.10 ± 0.67 and 1.47 ± 0.69, respectively; p=0.042) and mean VAS (2.13 ± 1.17 and 2.97 ± 1.35, respectively; p=0.034) scores. Conclusions: Pain responses in patients undergoing PRP with a 30-ms pulse duration were significantly milder in the NAVILAS group than in the PASCAL group.

title: Serous retinal detachment in patients with macular edema secondary to branch retinal vein occlusion

description: ABSTRACT Purpose: The aim of the present study was to evaluate visual acuity (VA) and central macular thickness (CMT) to assess the influence of serous retinal detachment (SRD) in eyes with macular edema (ME) secondary to branch retinal vein occlusion (BRVO). Methods: Sixty-one eyes with BRVO from 61 patients with ME were analyzed and divided into two groups according to the spectral domain optical coherence tomography (OCT) findings of SRD and cystoid macular edema (CME). All patients underwent complete ophthalmic examinations and OCT measurements (Cirrus, Carl Zeiss Meditec Inc, Dublin, CA). Patients with marked retinal hemorrhage, diabetic retinopathy, previous laser photocoagulation, and/or intravitreal injection were excluded. Results: The mean age of included patients (37 males, 24 females) was 65.4 ± 11.4 (53-77) years. There were 21 patients with SRD and 40 patients with CME. All of the 21 patients with SRD had CME. VA was significantly worse in the SRD group compared with the CME (non-SRD) group (0.82 ± 0.34 logMAR vs 0.64 ± 0.38 logMAR; P=0.005). Conversely, CMT was significantly greater in the SRD group than in the CME group (465 ± 115 µ vs 387 ± 85 µ; P=0.00004). Conclusion: SRD may be associated with decreased VA. The prognosis of patients with BRVO and SRD requires further investigation.

title: Mean platelet volume in patients with retinal artery occlusion

description: ABSTRACT Purpose: The aim of this study was to investigate the mean platelet volume (MPV) of patients with retinal artery occlusion (RAO). Methods: Thirty-seven patients diagnosed with RAO and 32 control subjects were included in this retrospective study. Retinal artery occlusion was diagnosed on the basis of clinical examination and fundus fluorescein angiography. All participants underwent complete ocular examination, and MPV, hematocrit, hemoglobin, and platelet counts were recorded. RAO patient data were compared with those of the control subjects. Results: Patients with RAO had significantly higher MPV values (7.96 ± 1.2 fL) compared with control subjects (7.33 ± 0.7 fL, p&lt;0.001). No significant difference was found with regard to platelet count between the RAO group and the control group (262 ± 70.1 × 109/L and 251 ± 56.6 × 109/L, respectively, p=0.50). MPV was an independent predictor of RAO [odds ratio (OR)=0.50; 95% confidence interval (CI)=0.28-0.89; p=0.019). Conclusions: Our results demonstrated that MPV values were significantly higher in patients with RAO, suggesting that larger platelets may contribute to the pathogenesis of the RAOs.

title: Intrastromal corneal ring segments delay corneal grafting in patients with keratoconus

description: ABSTRACT Purpose: To assess the impact of intrastromal corneal ring segments (ICRS) as a surgical alternative to corneal grafting in patients with keratoconus who were scheduled for a corneal transplant. Methods: This single-surgeon, single-center, retrospective, observational case series study included 19 eyes of 18 patients (mean age, 23.36 ± 6.22 years) with a confirmed diagnosis of keratoconus. These patients were enrolled from the State of Goiás, Brazil corneal graft waiting list. Following extensive pre-operative testing, including the measurement of best-corrected visual acuity (BCVA), applanation tonometry, biomicroscopy, funduscopy, pachymetry, and corneal topography, patients were implanted with Keraring® ICRS. Patients underwent clinical examination at postoperative days 1, 7, 30, 90, and 180 and were examined again 2 years following surgery. Results: At the 2-year cut-off following ICRS implantation (mean follow-up, 28.72 ± 4.71 months), there was a statistically significant improvement in BCVA (logMAR) from 0.59 ± 0.35 preoperatively to 0.35 ± 0.45 postoperatively ( p &lt;0.01). Three of 19 eyes (15.8%) still required keratoplasty. In the remaining patients (84.2%), BCVA was managed with spectacles (52.6%) or contact lenses (31.6%). One patient developed infectious keratitis, requiring removal of ICR at the first postoperative visit. Conclusion: ICRS implantation may be a surgical alternative to keratoplasty in patients with keratoconus. This procedure may delay or even eliminate the need for keratoplasty in such patients.

title: Ophthalmological findings in infants with microcephaly and presumable intra-uterus Zika virus infection

description: ABSTRACT Purpose: In 2015, a twenty-fold increase in the prevalence of microcephaly in Brazil was reported, and the Ministry of Health associated this abnormal prevalence with the maternal-fetal Zika virus (ZIKV) transmission. Methods: We assessed the ophthalmological findings of ten mothers and their infants that had been clinically diagnosed with ZIKV-related microcephaly and presented ocular abnormalities, born from May to December 2015. Results: Seven mothers (70.0%) referred symptoms during pregnancy (malaise, rash and arthralgia), of which six (85.7%) were in the first trimester. At the time of exam, no ophthalmological abnormalities were identified in the mothers and they did not report ocular symptoms during pregnancy. Serology was negative in all infants for Toxoplasmosis, Rubella, Cytomegalovirus, Syphilis and Human Immunodeficiency Viruses. Ocular findings included macular alterations (gross pigment mottling and/or chorioretinal atrophy) in fifteen eyes (75.0%), and optic nerve abnormalities (hypoplasia with double-ring sign, pallor, and/or increased cup-to-disk ratio) in nine eyes (45.0%). Conclusions: Patients presented normal anterior segment and important macular and optic nerve abnormalities. Further studies will assess the visual significance of these alterations.
