Purpose: To analyze the visual and anatomical outcomes for eyes with rhegmatogenous retinal detachment (RRD) and advanced proliferative vitreoretinopathy (PVR) undergoing giant peripheral retinotomy (GPR) using 25-gauge pars plana vitrectomy (PPV).

Methods: In this retrospective multi-center study, patients with RRD with either anteroposterior or circumferential retinal shortening and advanced PVR requiring more than 90-degree GPR with/without relaxing retinotomy were included. Subjects of either gender, any age group, and with complete surgical notes were included.

Cauda equina syndrome as the initial presentation of uveal melanoma metastasis.

Purpose: Uveal melanoma extension to the central nervous system (CNS) is exceedingly rare, and can occur through optic nerve invasion. We report a rare clinical case that presented with cauda equina syndrome as the initial manifestation of metastasis of choroidal melanoma, and showed neurotropic extension by histopathology. Our patient did not demonstrate any evidence of systemic metastasis otherwise.

NOVEL SURGICAL TECHNIQUE TO REMOVE RETAINED SUBFOVEAL PERFLUOROCARBON LIQUID.

Purpose: To describe a novel surgical technique to remove retained subfoveal perfluorocarbon liquid (PFCL).

Methods: After setting up for 23-G pars plana vitrectomy, a 38-G flexible-tip macular hydrodissection cannula connected to the automated viscous fluid infusion kit was used to create a small retinotomy approximately 700 μm to 800 μm inferior to the fovea and induce macular detachment involving the retained PFCL bubble. The flexible cannula was bent at its junction with the shaft and was carefully advanced through the same retinotomy into the subretinal space to access and directly aspirate the retained subfoveal PFCL bubble.

Interferon-α-induced retinopathy in chronic hepatitis C treatment: summary, considerations, and recommendations.

Interferons are cytokines that regulate the host's response to viral infection, particularly in the setting of the immunologic response to the hepatitis C virus (HCV). While the virus has the ability to evade the host's innate and specific immunity, exogenous interferon-α with combined ribavirin, treatments have been found to achieve a significant sustained viral response in subgroups of patients with chronic HCV. One of the major side effects of interferon-α is an ocular retinopathy characterized by flame-shaped hemorrhages and cotton wool spots visualized on funduscopic examination.

High-Resolution Imaging of Parafoveal Cones in Different Stages of Diabetic Retinopathy Using Adaptive Optics Fundus Camera.

Purpose: To assess cone density as a marker of early signs of retinopathy in patients with type II diabetes mellitus.

Methods: An adaptive optics (AO) retinal camera (rtx1™; Imagine Eyes, Orsay, France) was used to acquire images of parafoveal cones from patients with type II diabetes mellitus with or without retinopathy and from healthy controls with no known systemic or ocular disease. Cone mosaic was captured at 0° and 2°eccentricities along the horizontal and vertical meridians.

Aflibercept for neovascular age-related macular degeneration.

Background: Central vision loss caused by age-related macular degeneration (AMD) is the leading cause of blindness among the elderly in developed countries. Neovascular AMD is characterized by choroidal neovascularization (CNV). Growth of new blood vessels in patients with neovascular AMD is driven by a complex process that involves a signal protein called vascular endothelial growth factor A (VEGF-A).

Pharmacologic Vitreolysis in Vascular Diseases of the Retina.

Vascular diseases of the retina such as diabetic retinopathy and vascular occlusions account for a large proportion of visual morbidity and blindness worldwide. The role of vitreous in the pathogenesis of these conditions has been increasingly recognized. Despite advances in the surgical technique of pars plana vitrectomy, the use of intravitreal agents for the lysis of vitreous has received attention, guided largely by promising results from the trials involving patients with non-vascular retinal diseases such as vitreomacular traction.

Platelet derived growth factor inhibitors: A potential therapeutic approach for ocular neovascularization.

Retinochoroidal vascular diseases are the leading causes of blindness in the developed world. They include diabetic retinopathy (DR), retinal vein occlusion, retinopathy of prematurity, age-related macular degeneration (AMD), and pathological myopia, among many others. Several different therapies are currently under consideration for the aforementioned disorders.

Variation of choroidal thickness and vessel diameter in patients with posterior non-infectious uveitis.

Background: Choroidal thickness (CTh) and choroidal vessel diameter (VD) in the Haler's layer were evaluated as markers of inflammatory insult in non-infectious uveitis (NIU). Spectral-domain optical coherence tomography (Spectralis®, Heidelberg Engineering Inc.) scans were acquired from 23 normal subjects (39 eyes - group 1), 7 subjects with high myopia (14 eyes - group 2), and 19 patients with NIU (23 eyes - group 3).

Endogenous endophthalmitis: diagnosis, management, and prognosis.

Endogenous endophthalmitis is an ophthalmic emergency that can have severe sight-threatening complications. It is often a diagnostic challenge because it can manifest at any age and is associated with a number of underlying predisposing factors. Microorganisms associated with this condition vary along a broad spectrum.

Background And Objective: To compare the anatomy of different retinal layers adjacent to areas of geographic atrophy (GA) to those of eyes with no known ocular diseases.

Patients And Methods: Spectral-domain optical coherence tomography (SD-OCT) scans from eyes with GA were retrospectively reviewed. Two scans with no findings suggestive of GA changes on OCT were selected from immediately above and/or below the edge of the lesions.

Combined systemic and ocular chemotherapy for anterior segment metastasis of systemic mantle cell lymphoma.

Background: Mantle cell lymphoma (MCL) is an aggressive subtype of non-Hodgkin's lymphoma that rarely metastasizes to the iris and the anterior segment. Blastic/pleomorphic morphology is thought to have an adverse effect on prognosis in MCL. MCL is resistant to conventional chemotherapeutic regimens with a tendency for multiple relapses.

Methods: SD-OCT raster scans of 12 eyes from 6 patients serologically diagnosed with AIR were evaluated. Retinal layers were segmented along a 5 mm horizontal scan passing through the fovea.

High-resolution adaptive optics findings in talc retinopathy.

Talc retinopathy is a recognized ocular condition characterized by the presence of small, yellow, glistening crystals found inside small retinal vessels and within different retinal layers. These crystals can be associated with retinal vascular occlusion and ischemia. Different diagnostic modalities have been used previously to characterize the retinal lesions in talc retinopathy.

Sustained-release fluocinolone acetonide intravitreal insert for macular edema: clinical pharmacology and safety evaluation.

Introduction: Inflammation plays a key role in the pathological processes leading to macular edema. Sustained release, low-dose intraocular corticosteroid delivery devices provide long-term anti-inflammatory therapy. Recently, a novel fluocinolone acetonide intravitreal insert (FAi, Iluvien), has been introduced with promising long-term results in the treatment of macular edema.

Introduction to microperimetry and its use in analysis of geographic atrophy in age-related macular degeneration.

Purpose Of Review: This article discusses recent advances in the fundus-guided perimetry (microperimetry) and its utilization in evaluation and monitoring of patients with geographic atrophy.

Recent Findings: Although best-corrected visual acuity has been gold standard in clinical practice for decades, it does not provide an entire assessment of visual function that determines daily activity and quality of life of a patient. Furthermore, psychophysical tests, including low-luminance visual acuity, reading speed, and contrast sensitivity, cannot be used to quantify retinal sensitivity or detect pattern of retinal dysfunction.
