The purpose of this study was to investigate the correlation between bacterial load of Chlamydia trachomatis as measured from quantitative polymerase chain reaction (qPCR) and the relative clinical severity of trachomatous inflammation. Individuals with trachoma from rural communities in Ethiopia had photographs taken as well as swabs obtained of the upper tarsal conjunctivas. Conjunctival swabs were processed with PCR assay, which provided quantitative results of ocular chlamydial load.

Frequency-doubling technology (FDT) and the Moorfields motion displacement test (MDT) are portable perimeters that have shown promise as potential screening tools for glaucoma. This study's goal was to determine the diagnostic accuracy of FDT and MDT for visual field defects and glaucoma.

Background And Objective: Macular atrophy (MA) contributes to declining vision during prolonged anti-vascular endothelial growth factor (VEGF) treatment in neovascular age-related macular degeneration (nAMD) so greater understanding of its incidence, evolution, and impact on visual acuity is merited.
Materials And Methods: This is a retrospective review of nAMD patients receiving anti-VEGF therapy for ≥ 5 years. Near-infrared reflectance images and vision data were extracted every 6 months.
Background/objectives: Tablet-based perimetry could be used to test for glaucomatous visual field defects in settings without easy access to perimeters, although few studies have assessed diagnostic accuracy of tablet-based tests. The goal of this study was to determine the diagnostic accuracy of iPad perimetry using the visualFields Easy application.
Subjects/methods: This was a prospective, cross-sectional study of patients undergoing their first Humphrey Field Analyser (HFA) visual field test at a glaucoma clinic in India.
Purpose: Outcomes of Acanthamoeba keratitis are often worse in India than in the United States. The goal of this study was to determine whether antiamoebic susceptibility patterns were different when comparing Acanthamoeba isolates from India with those of the United States.
Methods: Acanthamoeba isolates were obtained from corneal scrapings of 43 patients with infectious keratitis seen at the Francis I.

Purpose: To describe a patient with Cobb Syndrome, a rare congenital disorder characterized by cutaneous and spinal arteriovenous malformations, who was found to have bilateral optic nerve pits.
Observations: A 15-year-old boy diagnosed with Cobb Syndrome, manifesting as a large cutaneous port-wine stain associated with an underlying left paraspinous arteriovenous malformation resulting in severe scoliosis, presented for a screening ophthalmological exam. The patient had no visual symptoms.
