Background And Objective: To report clinical feasibility of non-mydriatic ultra-widefield (NMUWF) imaging and determine the prevalence of peripheral retinal pathology in comparison to standard single-field imaging in a primary care setting.
Patients And Methods: Six hundred and thirty-two subjects (1,260 eyes) who underwent NMUWF imaging during annual health screening from October 2015 through March 2016 were retrospectively identified. An automated algorithm processed the raw images into: (1) NMUWF image with mask/grid outline that delineates the center 45° field simulating standard single-field photograph and (2) single-field image comprising 45° posterior pole extracted from the corresponding NMUWF image.
Results: Mean age of patients was 59.6 years ± 7.5 years. Of the 1,260 eyes, 1,238 eyes (98.3%) were considered optimum for grading. NMUWF images detected peripheral retinal pathology in 228 eyes (18.4%) that were not visible on corresponding single-field images.
Conclusions: NMUWF imaging is feasible in a primary care setting, allows improved visualization of peripheral retinal pathology, and may therefore be useful for telemedicine screening. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:962-968.].

Introduction: Retinal capillary hemangioma (RCH) is a benign vascular hamartoma that can occur sporadically or as a manifestation of Von Hippel-Lindau (VHL) disease. If left untreated, it results in adverse ocular complications depending on its location and eventual visual loss.
Case Presentation: We present a 50-year-old man who was a known case of VHL with history of left eye vision loss in the left eye at the age of 30 years.
S100A8/A9 Promotes Dendritic Cell-Mediated Th17 Cell Response in Sjögren's Dry Eye Disease by Regulating the Acod1/STAT3 Pathway.

Purpose: To investigate the role of S100A8/A9 in the pathogenesis of Sjögren's dry eye disease (SjDED) and explore its potential mechanism of action.
Methods: S100A8/A9 expression was determined by western blot and quantitative real-time polymerase chain reaction (qRT-PCR). Tear secretion, corneal fluorescein staining, and hematoxylin and eosin staining were used to evaluate the effect of paquinimod, a S100A8/A9 inhibitor, on dry eye disease in nonobese diabetic (NOD) mice.

Purpose: To compare the assessment of clinically relevant retinal and choroidal lesions as well as optic nerve pathologies using a novel three-wavelength ultra-widefield (UWF) scanning laser ophthalmoscope with established retinal imaging techniques for ophthalmoscopic imaging.
Methods: Eighty eyes with a variety of retinal and choroidal lesions were assessed on the same time point using Topcon color fundus photography (CFP) montage, Optos red/green (RG), Heidelberg SPECTRALIS MultiColor 55-color montage (MCI), and novel Optos red/green/blue (RGB). Paired images of the optic nerve, retinal, or choroidal lesions were initially diagnosed based on CFP imaging.

Department of Ophthalmology, Ross Eye Institute, University at Buffalo, 1176 Main Street, Buffalo, NY, 14209, United States.
Purpose: We report a single case of ocular decompression retinopathy (ODR) following neodymium-doped yttrium aluminum garnet laser peripheral iridotomy (Nd:YAG LPI) for primary acute angle-closure glaucoma associated with delayed visual recovery secondary to optic nerve head edema and macular thickening.
Observations: A 56-year-old female patient presented to the emergency department with primary acute angle-closure glaucoma. After topical and IV therapy did not improve intraocular pressure (IOP), an Nd:YAG LPI was performed.
