Background: Contact lens discomfort (CLD) is a common problem for CL wearers, and patients with CLD often have changes in meibomian gland function and structure. In a Phase 2 trial AZR-MD-001 0.5% (AZR) ophthalmic ointment improved meibomian gland dysfunction (MGD) in non-lens wearers.

Purpose: To determine the efficacy and safety of AZR-MD-001 (0.5 % and 1.0 %) ophthalmic ointment, relative to vehicle, over 3-6 months of treatment, in participants with meibomian gland dysfunction (MGD).

Purpose: Meibomian gland dysfunction (MGD) is a chronic progressive disease with downstream effects on ocular signs and symptoms. AZR-MD-001 is a selenium sulfide ophthalmic ointment that was investigated as a potential treatment option for patients with MGD.

Methods: A Phase 2, multi-center, double-masked, parallel group study was conducted across 29 sites, with 245 patients randomized 1:1:1 to AZR-MD-001 0.

Purpose: Improving adherence to manage elevated intraocular pressure (IOP) remains an unmet need. A topical bimatoprost ocular insert was compared with twice-daily timolol eye drops in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT) treated for 6 months.

Design: Parallel-arm, multicenter, double-masked, randomized, controlled trial.

Purpose: To determine if Preferential Hyperacuity Perimetry (PHP) testing can detect the presence of retinal toxicity due to hydroxychloroquine (HCQ) or chloroquine administration.

Methods: Fifteen patients were divided into three groups. Five patients had confirmed HCQ or chloroquine toxicity, five patients had suspected HCQ toxicity, and five patients had history of long-term use of HCQ or chloroquine but no evidence of toxicity.

Purpose: To assess the ability of the Preferential Hyperacuity Perimeter (PreView PHP; Carl Zeiss Meditec, Dublin, CA) to detect recent-onset choroidal neovascularization (CNV) resulting from age-related macular degeneration (AMD) and to differentiate it from an intermediate stage of AMD.

Design: Prospective, comparative, concurrent, nonrandomized, multicenter study.

Participants: Eligible participants' study eyes had a corrected visual acuity of 20/160 or better and either untreated CNV from AMD diagnosed within the last 60 days or an intermediate stage of AMD.

Purpose: To compare the preferential hyperacuity perimeter (PHP) with an Amsler grid in detection of age-related macular degeneration (AMD).

Methods: Patients underwent refraction, visual acuity examination, PHP, Amsler grid examination, and macular photography.

Results: One hundred fifty patients participated in the trial.

Background And Objective: To examine a new high-resolution kinetic mapping method for scotoma in age-related macular degeneration.

Patients And Methods: A computer-based program for kinetic visual field mapping was tested in 10 healthy subjects and 14 patients with age-related macular degeneration and fixed preferred retinal locus. The stimulus was presented using a back projector on a screen located 40 cm from the subject.

Purpose: To study whether cell membrane mechanical fluctuation (CMF) of red blood cells (RBCs) are attenuated in non-proliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR).

Patients And Methods: Point dark-field microscopy-based recordings of local membrane displacements (frequency 0.3-25 Hz) were compared between type 2 diabetes patients with mild-to-moderate and severe NPDR and type 2 diabetes patients with PDR.

Background And Objective: The aim of this study was to investigate the effect of interferon alpha-2a, an angiogenesis inhibitor, on eyes with active neovascularization after complete laser panretinal photocoagulation treatment.

Patients And Methods: Eight patients with active neovascularization persisting for 6 months or more after completion of full panretinal photocoagulation were included in the study. All patients were treated with subcutaneous injections of 6 million international units of interferon alpha-2a, 3 times a week, for an average period of 10 months.

Purpose: To investigate a method that uses hyperacuity, the Macular Computerized Psychophysical Test (MCPT), to evaluate the central macular visual field in patients with age-related macular degeneration (AMD).

Design: Prospective case-control study of a diagnostic test.

Participants And Controls: One hundred eight eyes of 108 Patients with AMD and 51 eyes of 51 age-matched patients with no retinal disease.

Purpose: The study aimed to determine whether detectable concentrations of colchicine are present in the tear fluid of treated patients with familial Mediterranean fever (FMF) and thus demonstrate a possible route by which colchicine reaches the corneal surface.

Methods: Tear fluid samples (50-100 microL) were collected from eight FMF patients on long-term colchicine treatment. Colchicine tear fluid concentrations were determined in all patients by radioimmunoassay using goat anticolchicine antibodies and [3H]colchicine (Dupont, Wilmington, DE).

The Retinal Thickness Analyzer is a laser slit biomicroscopy imaging device that produces accurate measurements of retinal thickness and displays the images in a two-dimensional pattern, superimposed on a fundus image. This article reports a patient with decreased vision following branch retinal vein occlusion in whom the Retinal Thickness Analyzer was used to establish the diagnosis of a macular lamellar hole that was not apparent clinically.
