PURPOSE: Previous studies have yielded conflicting results regarding whether serum lipid levels are associated with retinal hard exudates in diabetic retinopathy. The majority of studies have assessed hard exudates only as a dichotomous trait (presence vs. absence) and included limited numbers of African Americans (AA). The purpose of this study was to determine if there are any associations between serum lipid levels and hard exudates in AA with type 2 diabetes (T2D). METHODS: 890 AA participants with T2D were enrolled from 5 sites...

PURPOSE: To evaluate the feasibility and efficacy of mini-scleral design (MSD) contact lenses to treat keratoconus patients who were unsatisfied with the results of corneal inlay. METHODS: In this prospective interventional case series, 9 eyes of 6 keratoconus patients who were unsatisfied with the results of corneal inlay were fitted with MSD contact lenses. Demographic data, uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), and higher order aberrations (HOAs) were evaluated before contact lens fitting...

Purpose. To compare subfoveal choroidal, central retinal, and peripapillary nerve fiber layer (RNFL) thickness after panretinal photocoagulation (PRP) with red and green laser in diabetic patients. Study Design. Randomized clinical trial. Methods. A total of 50 patients with bilateral proliferative diabetic retinopathy and no diabetic macular edema underwent PRP. One eye was randomly assigned to red or green laser. Subfoveal choroidal, central retinal, and RNFL thicknesses were evaluated at baseline and 6 weeks after treatment...

PURPOSE: Management of granulomatosis with polyangiitis (GPA)-associated peripheral ulcerative keratitis (PUK) is challenging and lacks definite guidelines. We aimed to summarize our treatment and outcome experience with patients with GPA-PUK. METHODS: The Massachusetts Eye Research and Surgery Institution patient database was searched from 2005 to 2015 to identify patients with diagnosis of PUK who suffered from GPA. Individual patient histories were examined, and treatment strategies and outcomes were summarized...

OBJECTIVE: To test the applicability of existing retinopathy of prematurity (ROP) guidelines on Iranian patients and to develop novel ROP screening criteria in Iran. METHODS: Both eyes of 1932 infants born ≤37 weeks of gestation and/or weighting ≤3000 g were included in this prospective cohort study that was conducted across nine neonatal intensive care units and a tertiary eye hospital ROP clinic. The patients were examined for ROP and the need for treatment (type 1 ROP or worse)...

PURPOSE: To evaluate the feasibility of screening for retinopathy of prematurity (ROP) by assessing the pupillary response to mydriatics. METHODS: This observational case series included 134 eyes of 67 premature infants with birth weight less than 2,000 grams and gestational age less than 33 weeks. A composite eye drop composed of phenylephrine 1%, tetracaine and tropicamide 0.5% was applied 3 times within 5-minute intervals and pupil diameters were measured. The eyes were examined by experienced ROP specialists using an indirect ophthalmoscope...
