PURPOSE: To compare optical coherence tomography angiography (OCTA) review strategies for optimizing choroidal neovascularization (CNV) detection. METHODS: Eyes with CNV in the differential diagnosis were imaged with the Avanti RTVue XR HD (Optovue, Fremont, CA). Three modalities of review for CNV presence were used in each case: a single report generated using automated segmentation within Avanti software; a continuous slab descent video OCTA export; and a manual segmentation approach using cross-sectional OCT with decorrelation signal overlay...

Alexander Barash, Toco Y P Chui, Patricia Garcia, Richard B Rosen
PURPOSE: Intravitreal injections acutely and temporarily increase intraocular pressure (IOP), and this may have cumulative long-term effects including an increased risk for glaucoma surgery. This study was designed to measure retinal perfusion density changes on optical coherence tomography (OCT) angiography and OCT thickness alterations associated with acutely increased IOP after intravitreal injections. METHODS: Retrospective observational clinical study of 40 eyes (39 patients) with various retinopathies from October 2016 to June 2017 at a tertiary care retina clinic in NYC...

PURPOSE: To characterize functional and structural changes in hydroxychloroquine (HCQ) retinal toxicity after drug cessation. METHODS: Twenty-two patients (91% female; mean age 58.7 ± 11.4 years; mean duration of HCQ treatment 161.1 ± 90 months; mean dose 5.9 ± 1.9 mg/kg) with detected HCQ retinopathy were monitored for 6 months to 82 months after HCQ cessation with multimodal imaging including spectral domain optical coherence tomography and fundus autofluorescence imaging at 488 nm (standard) and 787 nm (near-infrared autofluorescence)...

PURPOSE: To evaluate the effect of tumor necrosis factor (TNF) inhibitor therapy on ocular relapses in patients with Susac syndrome. METHODS: Multicenter retrospective cohort study of patients diagnosed with Susac syndrome according to classical clinical criteria. We evaluated the disease activity before and after introduction of anti-TNF therapy and its value as a steroid-sparing agent. RESULTS: Five patients were included. All were initially treated with a combination of corticosteroids and classical immunosuppressive drugs...

PURPOSE: To report toxic posterior segment syndrome after dropless cataract surgery using locally compounded triamcinolone-moxifloxacin. METHODS: A retrospective case review of 7 patients presenting with a decrease in visual acuity after dropless cataract surgery.

PURPOSE: To compare the impact of surgical timing on anatomical and functional outcomes of vitrectomy for open-globe injury. METHODS: Fifty-three patients were entered into this prospective open-label study, with 26 patients randomized into early surgery group (vitrectomy conducted within 4 days) and 27 into delayed surgery group (vitrectomy performed between 10-14 days after injury). Six-month data were available for 46 patients and 7 were lost to follow-up. The main outcome measures were incidence of traumatic proliferative vitreoretinopathy assessed intraoperatively and postoperatively, reattachment of retina, eye enucleation, improvement of the best-corrected visual acuity, and complications...

PURPOSE: To test optical coherence tomography leakage in the identification and quantification of choroidal neovascularization-related fluid, its change after anti-vascular endothelial growth factor therapy in neovascular age-related macular degeneration eyes and its relation to functional outcome. METHODS: Prospective analysis of a cohort of neovascular age-related macular degeneration cases treated with 2.0-mg intravitreal aflibercept. Eyes included were analyzed before, 1-week, and 1-month after one injection...

PURPOSE: We hypothesized that severe forms of neovascular age-related macular degeneration (AMD) such as large pigment epithelial detachments poorly responding to anti-vascular endothelial growth factor therapy might present a distinct genotype compared with overall series of neovascular AMD. METHODS: This is a multicenter genetic association study. Sixty-eight patients presenting pigment epithelial detachments resistant to ranibizumab (issued from ARI2 study, register number NCT02157077 on clinicaltrials...

PURPOSE: Mitogen-activates protein kinase (MAPK) inhibitors, particularly MEK inhibitors, have shifted the treatment paradigm for metastatic BRAF-mutant cutaneous melanoma; however, oncologists, ophthalmologists, and patients have noticed different toxicities of variable importance. This review aims to provide an update of the ocular adverse events (OAEs), especially retinal toxicity, associated with the use of MEK inhibitors. METHODS: We conducted a scientific literature search using the PubMed database up to July 2018 with the terms "MEK inhibitors" with a "review" filter and "MEK inhibitors" with a "clinical trials" filter...

PURPOSE: To report the clinical presentation and management outcome of patients with endophthalmitis caused by Enterococcus species and to report the susceptibility profile of the isolates. METHODS: Twenty-nine cases with culture-proven Enterococcus endophthalmitis from January 2005 to May 2018 underwent vitrectomy/vitreous biopsy, intravitreal antibiotic with or without additional procedures. The undiluted vitreous was subjected to microbiologic evaluation. A favorable anatomical outcome was defined as preservation of the globe, absence of hypotony, attached retina, and absence of active inflammation at the last visit...

PURPOSE: To demonstrate the effect of averaging multiple en face optical coherence tomography angiography images on the correlation between retinal microvasculature quantitative metrics and best-corrected visual acuity (BCVA) in eyes with retinal vein occlusion. METHODS: A cross-sectional cohort with unilateral retinal vein occlusion was imaged in both eyes. Five 3 mm × 3-mm spectral domain optical coherence tomography angiography images were averaged, and quantitative parameters from averaged versus single images were correlated with logMAR BCVA...

PURPOSE: To evaluate choroidal structural changes occurring over time in geographic atrophy (GA) secondary to age-related macular degeneration using choroidal vascularity index (CVI). METHODS: Enhanced-depth imaging optical coherence tomography scans of 34 patients with GA and 32 control subjects were retrospectively analyzed. Data were collected at baseline and after a mean follow-up of 18.3 ± 8.3 months. Choroidal images were binarized using the ImageJ software, and the luminal area and stromal area were segmented...

PURPOSE: To study the etiology, clinical features, management options, and visual prognosis in various types of atypical macular holes (MHs). METHODS: A review of the literature was performed, which focused on the etiopathogenesis of atypical or secondary MHs, their differentiating clinical features, management strategies, and varied clinical outcomes. Idiopathic or age-related, myopic, and traumatic MHs were excluded. RESULTS: Atypical or secondary MHs arise out of concurrent ocular pathologies (dystrophy, degeneration, or infections) and laser/surgery...
