title: The effects of pharmacological accommodation and cycloplegia on axial length and choroidal thickness

description: ABSTRACT Purpose: To investigate the effects of pharmacological accommodation and cycloplegia on ocular measurements. Methods: Thirty-three healthy subjects [mean (±SD) age, 32.97 (±5.21) years] volunteered to participate in the study. Measurement of the axial length, macular and choroidal thickness, refractive error, and corneal topography, as well as anterior segment imaging, were performed. After these procedures, pharmacological accommodation was induced by applying pilocarpine eye drops (pilocarpine hydrochloride 2%), and the measurements were repeated. The measurements were repeated again after full cycloplegia was induced using cyclopentolate eye drops (cyclopentolate hydrochloride 1%). The correlations between the measurements were evaluated. Results: A significant increase in subfoveal choroidal thickness after applying 2% pilocarpine was identified (without the drops, 319.36 ± 90.08 µm; with pilocarpine instillation, 341.60 ± 99.19 µm; with cyclopentolate instillation, 318.36 ± 103.0 µm; p&lt;0.001). A significant increase in the axial length was also detected (without the drops, 23.26 ± 0.83 mm; with pilocarpine instillation, 23.29 ± 0.84 mm; with cyclopentolate instillation, 23.27 ± 0.84 mm; p=0.003). Comparing pharmacological accommodation and cycloplegia revealed a significant difference in central macular thickness (with pilocarpine instillation, 262.27 ± 19.34 µm; with cyclopentolate instillation, 265.93 ± 17.91 µm; p=0.016). Pilocarpine-related miosis (p&lt;0.001) and myopic shift (p&lt;0.001) were more severe in blue eyes vs. brown eyes. Conclusion: Pharmacological accommodation may change ocular measurements, such as choroidal thickness and axial length. This condition should be considered when performing ocular measurements, such as intraocular lens power calculations.

title: Optimal timing of capsular tension ring implantation in pseudoexfoliation syndrome

description: ABSTRACT Purpose: The aim of this study was to evaluate the appropriate timing of capsular tension ring implantation in cases of zonular weakness due to pseudoexfoliation syndrome. Methods: This prospective, comparative study was performed at the Ophthalmology Department of Inonu University, Malatya, Turkey. There were 43 patients included in the study. Group 1 (16 patients) had early capsular tension ring implantation, and group 2 (27 patients) had late capsular tension ring implantation. Patients with pseudoexfoliation syndrome who underwent phacoemulsification surgery, posterior chamber intraocular lens implantation, and capsular tension ring implantation were included in the study. Intraoperative complications and difficulties with either capsular tension ring implantation or cortex removal were evaluated in each eye. Results: There was no significant difference between the groups in the difficulty of capsular tension ring implantation (p=0.124). The difficulty of cortex removal differed significantly between the groups (p=0.003). Intraoperative complications were observed in 3 patients in group 1 and 11 patients in group 2; the difference between the groups was not significant (p=0.18). Posterior capsule fluctuations were observed in 8 patients (29.5%) in group 2, which resulted in posterior capsule rupture in 2 patients. Conclusions: Cortex removal is more difficult with early capsular tension ring implantation, and posterior capsule fluctuations may cause problems with late capsular tension ring implantation. The surgeon must consider the risk-to-benefit ratio of early versus late insertion for the optimal timing of capsular tension ring implantation.

title: Acute corneal melting one week after an uncomplicated cataract surgery in a patient who previously underwent eyelid radiation and with undiagnosed rheumatoid arthritis: a case report

description: ABSTRACT This is a rare case report of acute, paracentral corneal melting and perforation occurring 1 week after an uneventful cataract surgery, with discussions on possible pathogenetic mechanisms. Relevant literature was also reviewed. Herein, a case of an 86-year-old woman with acute, paracentral, and sterile corneal melting and perforation in her left eye at 1 week after an uncomplicated cataract extraction is described. This occurs at the base of ocular surface disorders due to previous radiation of her lower eyelid and cheeks for the treatment of cancer and previously undiagnosed rheumatoid arthritis. She underwent surgical treatment using Gundersen’s conjunctival flap for the existing perforation due to low visual expectancies and reluctance to undergo corneal keratoplasty due to the risk of corneal graft rejection. The risk of coming across an acute corneal melting after an uncomplicated cataract surgery in the eyes with ocular surface disorders should always be considered.

title: Corneal and anterior chamber morphology in patients with nonınfectious ıntraocular ınflammation

description: ABSTRACT Purpose: To evaluate the corneal and anterior chamber morphology in phakic eyes with noninfectious intraocular inflammation. Methods: This study included 59 eyes with active uveitis, 62 with inactive uveitis, and 95 healthy eyes. Corneal endothelial cell density, hexagonal cell ratio, coefficient of variation (CV), corneal thickness and volume, maximum keratometry, and anterior chamber volume and depth (ACD) measurements were performed using a specular microscope and Pentacam HR. Results: The mean duration of uveitis was 24.6 ± 40.5 (0-180) months. The mean number of uveitis attacks was 2.8 ± 3.0 (1-20). Coefficient of variation was significantly higher in the active uveitis group compared with inactive uveitis group (p=0.017, Post Hoc Tukey). Anterior segment parameters other than coefficient of variation were not significantly different between active/inactive uveitis and control groups (p&gt;0.05). Multiple linear regression analysis showed that coefficient of variation was greater in active uveitis compared with inactive uveitis after adjusting for the duration of uveitis, type of uveitis, having a rheumatologic disease, and having immunosuppressive treatment (p=0.003). The duration of uveitis and number of attacks were not significantly correlated with ocular parameters (p&gt;0.05, Spearman’s correlation). The difference in parameters was not significant based on uveitis type (p&gt;0.05). Conclusions: Coefficient of variation was higher in eyes with active uveitis than that in eyes with inactive uveitis, whereas corneal endothelial cell density and anterior chamber morphology did not significantly differ between active/inactive uveitis and control groups.

title: Probing for congenital nasolacrimal duct obstruction: a systematic review and meta-analysis of randomized clinical trials

description: ABSTRACT Purpose: Lacrimal probing is the treatment of choice for congenital nasolacrimal duct obstruction that does not have a spontaneous resolution; however, there is no consensus about the best time for probing and if it is superior to other therapies. The present study aimed to evaluate the effectiveness of lacrimal probing compared with other treatments/no intervention to treat congenital nasolacrimal duct obstruction. Methods: A systematic review of literature in PubMed, EMBASE, CENTRAL, clinicaltrials.gov, and LILACS databases up to December 2019 was performed. Randomized clinical trials that enrolled children diagnosed with congenital nasolacrimal duct obstruction and undergoing lacrimal probing were considered. Data extraction and a risk of bias assessment were conducted independently and in duplicate. The overall quality of evidence for each outcome was conducted using the Grading of Recommendations, Assessment, Development, and Evaluation classification system. Results: Four randomized clinical trials involving 423 participants were eligible. No statistically significant differences were observed in resolution rates between early probing and observation/late probing (two studies; risk ratio 1.00 [95% confidence interval 0.76-1.33]; p=0.99; low certainty evidence). One study reported better resolution rates with bicanalicular silicone stent intubation compared with late probing in the complex congenital nasolacrimal duct obstruction cases subgroup (risk ratio 0.56 [95% confidence interval 0.34-0.92]; p=0.02; moderate certainty evidence). Conclusions: Low certainty evidence suggests that early probing has the same success rate as late probing. Evidence of moderate certainty suggests that late probing has a lower success rate than bicanalicular silastic intubation in patients with complex congenital nasolacrimal duct obstructione.

title: Punctate inner choroidopathy with atypical presentation

description: ABSTRACT We report a case of a young Caucasian female presenting with sudden decrease of vision in the left eye, metamorphopsia, and nasal scotoma. Past medical history revealed a diagnosis of myasthenia gravis, which was currently treated with azathioprine, pyridostigmine, and prednisone. Ophthalmological examination showed fundus with clear vitreous and yellow-white lesions that were isolated and perimacular in the right eye, multiple and confluent in the macula, and punctate in periphery in the left eye. Laboratory workup ruled out the presence of infectious and inflammatory diseases. Fundus autofluorescence disclosed hypoautoflurescence with hyperfluorescent margins corresponding to the lesions observed in both eyes and the angiogram revealed hyperfluorescence since early phases without late leakage. Spectral-domain optical coherence tomography showed areas of intermittent retinal pigment epithelium elevations and disruption of the ellipsoid zone. She was diagnosed with punctate inner choroidopathy and then treated with an increased dose of daily prednisone, which resulted in progressive improvement of her visual acuity and anatomical status.

title: Visual outcomes of audio-luminous biofeedback training for a child with idiopathic nystagmus

description: ABSTRACT Microperimetry biofeedback training is a vision rehabilitation method that involves the training of attention and oculomotor control, and the rehabilitation of poorly located and non-functional preferred retinal loci. It can significantly improve distance and near visual acuity in age-related macular degeneration. Previous studies have shown that biofeedback training using electrical nystagmography can reduce nystagmus amplitude and increase foveation time. However, these improvements have not been sustained following training sessions. We hereby report a pediatric case of idiopathic nystagmus in an 11-year old patient treated with microperimetric biofeedback to improve visual acuity and fixation stability. The training had a beneficial impact, positively affecting fixation stability as well as distance and near reading vision. Subjectively, improvement in quality of life was also reported. Conversely to previous studies, the positive effects in this case were maintained for as long as twelve months following therapy. To the best of our knowledge, this is the first case with long-term benefits to be reported in the literature.
