PURPOSE: To study the patterns of vitreous incarceration at sclerotomy sites by ultrasound biomicroscopy in patients subjected to valved or nonvalved small-gauge pars plana vitrectomy. METHODS: A prospective comparative study of 88 eyes affected by epiretinal membrane and macular hole. Patients were divided into four groups: valved or nonvalved 23-gauge (16 eyes each) and valved or nonvalved 25-gauge (20 eyes each); their vitreal disposition was compared by ultrasound biomicroscopy...

PURPOSE: This report aims at expanding the current knowledge of retinal microanatomy in children with incontinentia pigmenti using hand-held spectral domain optical coherence tomography (SDOCT). METHODS: We reviewed OCT scans from 7 children (4 weeks-13 years) obtained either in the clinic or during an examination under anesthesia. The scans were analyzed for anatomical changes in the outer and inner retina, by certified graders. Medical records were assessed for systemic findings...

BACKGROUND: The process of emmetropization is the adjustment of the length of the optical axis to the given optical properties of the cornea and lens after the end of the second year of life. Since its underlying mechanisms have not been fully explored yet, we reviewed findings available in the literature to discuss its potential etiology and the mechanism of myopization as an overshooting of emmetropization. METHODS: Literature review. RESULTS: The process of emmetropization occurs by axial elongation...

PURPOSE: To investigate the incidence rate and risk factors for development of retinal pigment epithelial (RPE) atrophy during anti-vascular endothelial growth factor (anti-VEGF) treatment for retinal angiomatous proliferation. METHODS: This study included 46 eyes with treatment-naive retinal angiomatous proliferation. All patients were treated with ranibizumab or aflibercept injections. Color fundus photography, spectral-domain optical coherence tomography, and fundus autofluorescence were evaluated for RPE atrophy diagnosis...

PURPOSE: To investigate the morphologic changes on optical coherence tomography angiography (OCTA) of treatment-naive Type 3 neovascularization secondary to exudative age-related macular degeneration after 1 year of anti-vascular endothelial growth factor therapy. METHODS: Consecutive patients diagnosed with treatment-naive early-stage Type 3 neovascularization were enrolled in this retrospective study. All patients underwent color fundus photographs/MultiColor (Heidelberg Engineering) imaging, fluorescein angiography, indocyanine green angiography, structural spectral domain OCT, and OCTA Optovue RTVue XR Avanti (Optovue) at baseline, and repeated OCTA and structural spectral domain OCT at Month 12...

PURPOSE: To analyze macular pigment (MP) amount and distribution in patients with macular telangiectasia Type 2 receiving oral zeaxanthin supplementation in a randomized, open-label, interventional trial. METHODS: Eight macular telangiectasia Type 2 patients were randomized to 10 mg or 20 mg of zeaxanthin per day. At each visit, best-corrected visual acuity, contrast sensitivity, fundus biomicroscopy, color fundus photography, autofluorescence imaging, optical coherence tomography, and serum carotenoid levels were tested...

PURPOSE: To study the outcomes of management of rhegmatogenous retinal detachment in eyes with chorioretinal colobomas. METHODS: A retrospective review of 119 patients (119 eyes) with chorioretinal colobomas who underwent surgical repair for rhegmatogenous retinal detachment was performed. Data were collected on the site of the retinal break, type of surgery, anatomical success, and complications. RESULTS: The most common location of the primary retinal break was the intercalary membrane in 58...

PURPOSE: To evaluate the influence of clinical and multimodal imaging parameters on the duration of acute central serous chorioretinopathy (CSCR) episodes. METHODS: Consecutive patients with first, treatment-naïve central serous chorioretinopathy episodes presenting within 20 days of symptoms onset were prospectively included. They were reevaluated 15 days to 20 days later, followed by monthly evaluation for 6 months. Subfoveal choroidal thickness (SFCT), fluorescein leakage intensity on fluorescein angiography, elevation of retinal pigment epithelium (RPE) lesions at leakage sites, focal/multifocal pattern of indocyanine green angiography (ICGA) at baseline, time-dependent pattern of subretinal fluid (SRF) resorption on OCT using volume segmentation, history of corticosteroid intake and mean blood pressure were evaluated using univariate (Log rank test) and multivariate (Cox proportional hazard regression) survival analysis...

PURPOSE: To compare the results of vitrectomy with complete internal limiting membrane (ILM) removal and inverted ILM flap in the treatment of myopic macular hole (MMH). METHODS: Seventy eyes of 68 patients with MMH undergone pars-plana vitrectomy (PPV) with either complete ILM removal (n = 36, Group 1) or inverted ILM flap technique (n = 34, Group 2) were included in the study. Outcomes measured were the rate of MMH closure assessed by optical coherence tomography (OCT) and visual acuity (BCVA) at six months...

PURPOSE: To evaluate the safety of single intravitreal 2 mg ziv-aflibercept (0.08 mL) injections for the treatment of choroidal neovascular membranes (CNVM). METHODS: Eyes with choroidal neovascular membranes because of several conditions each received single intravitreal injections of 2 mg ziv-aflibercept (0.08 mL). Comprehensive ophthalmic examinations and detailed systemic evaluations were performed at baseline and Days 1, 7, and 30 after injections. Standard electroretinography was performed at baseline and Day 30...

PURPOSE: Establishing the correct diagnosis of a growing choroidal tumor can be difficult. METHODS: Clinical examination and ultrasound of a patient followed for what was thought to be a uveal melanoma. Fine-needle biopsy established the correct diagnosis. RESULTS: We demonstrate that fine-needle biopsy can correctly identify a very rare tumor, a myomelanocytic neoplasm. CONCLUSION: Myomelanocytic choroidal tumors can be diagnosed on fine-needle biopsy...

PURPOSE: To evaluate a new method for volumetric imaging of the preretinal space (also known as the subhyaloid, subcortical, or retrocortical space) and investigate differences in preretinal space volume in vitreomacular adhesion (VMA) and vitreomacular traction (VMT). METHODS: Nine patients with VMA and 13 with VMT were prospectively evaluated. Automatic inner limiting membrane line segmentation, which exploits graph search theory implementation, and posterior cortical vitreous line segmentation were performed on 141 horizontal spectral domain optical coherence tomography B-scans per patient...

PURPOSE: Retinal detachment is a frequent complication after removal of silicone oil (ROSO). A retrospective study was conducted to determine whether staining-assisted removal of silicone oil (st-ROSO) allowed better identification and removal of proliferative vitreoretinopathy (PVR) processes compared with a conventional removal of silicone oil technique. METHODS: All individuals underwent pars plana vitrectomy (PPV) and silicone oil fill-in for complicated retinal detachments...

PURPOSE: To evaluate construct and face validity of the Eyesi Binocular Indirect Ophthalmoscope Simulator. METHODS: The performance of 25 medical students (Group A) was compared with that of 17 ophthalmology and optometry trainees (Group B) on the Eyesi Binocular Indirect Ophthalmoscope Simulator. During the course of a single session, each participant viewed an orientation module followed by an instruction session and a demonstration case, and performed 6 cases of progressively increasing difficulty (4 levels) and a 10-question face validity questionnaire...

PURPOSE: To identify the prognostic variables relative to myopic choroidal neovascularization (CNV) treated with intravitreal ranibizumab/bevacizumab. METHODS: Forty-eight patients with myopic CNV were enrolled in a prospective, interventional, non-randomized 12-month study. Intravitreal ranibizumab/bevacizumab was administered in a pro-re-nata regimen and re-treatment was performed in the presence of angiographic leakage, intraretinal/subretinal fluid on optical coherence tomography, new hemorrhages, five-letter decrease and increased metamorphosia...

PURPOSE: To investigate associations between parafoveal microcirculatory status and foveal pathomorphology in eyes with macular edema (ME) secondary to retinal vein occlusion (RVO). METHODS: Ten consecutive patients (10 eyes) with acute retinal vein occlusion were enrolled, 9 eyes of which received intravitreal ranibizumab (IVR) injections. Foveal morphologic changes were examined via optical coherence tomography (OCT), and parafoveal circulatory status was assessed via adaptive optics scanning laser ophthalmoscopy (AO-SLO)...
