It has been known that retinal vein occlusion (RVO) is associated with chronic kidney disease, especially end-stage renal disease (ESRD). However, little is known about the effect of kidney transplantation (KT) on RVO incidence in ESRD patients. This study aimed to compare the incidence of RVO in KT recipients (n = 10,498), matched ESRD patients (n = 10,498), and healthy controls (HCs, n = 10,498), using a long-term population-based cohort. The incidence of RVO was 2.74, 5.68, and 1.02 per 1000 ...

Intraocular foreign bodies (IOFBs) are critical ophthalmic emergencies that require urgent diagnosis and treatment to prevent blindness or globe loss. This study aimed to examine the various clinical presentations of IOFBs, determine the prognostic factors for final visual outcomes, establish diagnostic protocols, and update treatment strategies for patients with IOFBs. We retrospectively reviewed patients with IOFBs between 2005 and 2019. The mean age of the patients was 46.7 years, and the mos...

Purpose: To investigate the role of ultra-widefield fluorescein angiography (UWFA) for monitoring therapeutic response to adalimumab in patients with Behcet's uveitis.Methods: Patients with Behcet's uveitis treated with adalimumab for ≥30 weeks were included. Intraocular inflammation, best-corrected visual acuity, systemic medications, and UWFA scores were evaluated.Results: Thirty-eight eyes of 20 patients were included. Significant decreases in grading of anterior chamber cells and vitreous ha...

PURPOSE To evaluate microstructural changes in cystoid macular edema in retinitis pigmentosa after intravitreal dexamethasone implant injection. METHODS In an extended cohort of a randomized trial of intravitreal dexamethasone implant for the management of retinitis pigmentosa-associated cystoid macular edema, microstructural changes during six months after the treatment were evaluated using spectral-domain optical coherence tomography. RESULTS Forty-two eyes were included, and all had cystoid s...

Abstract Purpose To investigate the clinical findings and natural course of patients with pigmented paravenous chorioretinal atrophy (PPCRA) using multimodal imaging. Design Retrospective, observational case series. Methods We reviewed the records of consecutive patients diagnosed with PPCRA at a single center and assessed serial fundus photographs, fundus autofluorescence (FAF), and spectral-domain optical coherence tomography images. Electrophysiological findings and visual field analysis were...

Importance Retinal biomarkers reflecting in vivo brain Alzheimer disease (AD) pathologic abnormalities could be a useful tool for screening cognitively normal (CN) individuals at the preclinical stage of AD. Objectives To investigate the association of both functional and structural alterations of the retina with in vivo AD pathologic abnormalities in CN older adults and model a screening tool for detection of preclinical AD. Design, Setting, and Participants This cross-sectional study included ...

Purpose To determine the mechanism of infection, clinical features, and risk factors of endophthalmitis after scleral fixation of an intraocular lens (IOL). Methods We included fifteen patients with infectious endophthalmitis after scleral fixation of an IOL between April 2004 and December 2017, as well as four patients found through a literature search. Thus, a total of nineteen patients were analyzed. Results Among nineteen eyes, infectious endophthalmitis developed at a mean of 23 months (ran...

PURPOSE To evaluate long-term results of photodynamic therapy (PDT) as a rescue treatment in patients with type 1 neovascularization refractory to intravitreal anti-vascular endothelial growth factor (VEGF). METHODS Patients who underwent reduced-fluence PDT for refractory type 1 neovascularization, which showed persistent subretinal and/or intraretinal fluid after three or more consecutive anti-VEGF treatments, and were followed up for ≥24 months were reviewed. RESULTS Seventy-eight eyes of 78 ...
