Vision Loss As a Presenting Feature of Wernicke Encephalopathy

The classic triad of Wernicke encephalopathy (WE) includes encephalopathy, ocular motor dysfunction, and gait ataxia. Often forgotten is that, in 1881, Wernicke also reported optic disc edema in two of his patients and disc hyperemia in all cases (1). We describe a patient with WE who primarily presented with vision loss and optic disc edema

Occult cause of uveitis-glaucoma-hyphema syndrome diagnosed during treatment with endocyclophotocoagulation (ECP).

PurposeTo describe uveitis-glaucoma-hyphema (UGH) syndrome secondary to a posterior chamber intraocular lens (PCIOL) within the capsular bag in which pathogenic changes to the ciliary body were observed and treated with endocyclophotocoagulation (ECP).ObservationsAn 85-year-old woman who had cataract surgery in her right eye four years ago presented with recurrent, unilateral, open-angle, hypertensive uveitis in her right eye. Her presentations were characterized by decreased vision, elevated intraocular pressure, corneal edema, a mixed anterior chamber reaction, and pigmented anterior vitreous cells. She had a frank vitreous hemorrhage during two episodes. Ultrasound biomicroscopy revealed a dense Soemmerring ring in her right eye without evidence of PCIOL-iris or PCIOL-ciliary body chafe. Subsequent ECP revealed whitened and atrophic ciliary processes adjacent to a tilted haptic within the capsular bag, consistent with chronic PCIOL-ciliary body chafe. ECP was applied to the affected ciliary processes, which successfully eliminated recurrences.Conclusions and importanceUGH can rarely occur due to an PCIOL within the capsular bag. In cases where ultrasound biomicroscopy (UBM) does not show abnormalities and clinical suspicion remains high, ECP can be a useful adjunct to observe and treat abnormalities of the ciliary body

Risk of failing both methotrexate and mycophenolate mofetil from the First-line Antimetabolites as Steroid-sparing Treatment (FAST) uveitis trial.

BackgroundThe antimetabolites methotrexate (MTX) and mycophenolate mofetil (MMF) are commonly used as initial corticosteroid-sparing treatment for uveitis. There is little data examining risk factors for failing both MTX and MMF. The objective of this study is to determine risk factors for failing both MTX and MMF in patients with non-infectious uveitis.Main bodyThis is a sub-analysis of the First-line Antimetabolites as Steroid-sparing Treatment (FAST) uveitis trial, which was an international, multicenter, block-randomized, observer-masked, comparative effectiveness trial comparing MTX and MMF as initial treatments for non-infectious uveitis. This study was undertaken at multiple referral centers in India, the United States, Australia, Saudi Arabia and Mexico between 2013 and 2017. A total of 137 patients who completed all 12 months of follow-up from the FAST trial, were included in this study. The primary outcome was failing both antimetabolites over the 12 months of the trial. Potential predictors included: age, sex, bilateral involvement, anatomic location of the uveitis, presence of cystoid macular edema (CME) and retinal vasculitis at baseline visit, uveitis duration, and country/study sites as risk factors for failing both MTX and MMF. The presence of retinal vasculitis posterior to the equator on fluorescein angiogram was associated with failing both MTX and MMF.ConclusionRetinal vasculitis may be a risk factor for failing multiple antimetabolites. Clinicians could consider more quickly advancing these patients to other medication classes, such as biologics
