The purpose of the study was to determine whether angle neovascularization can occur without pupillary margin neovascularization in central retinal vein occlusion (CRVO). ⋯ Angle neovascularization can occur without pupillary margin involvement in CRVO, implying the necessity of screening gonioscopy and supporting the Central Vein Occlusion Study conclusion (based on a photographic technique not used clinically).

The purpose of the study was to evaluate the effect of optic nerve head drusen (ONHD) on nerve fiber layer (NFL) thickness by visual field testing, red-free photography of NFL, and optical coherence tomography (OCT). ⋯ Optical coherence tomography is able to detect NFL thinning in eyes with ONHD and appears to be a sensitive and early indicator of NFL thinning. Increased numbers of clinically visible ONHD correlated with NFL thinning shown by OCT measurements and both visual field defects and NFL loss seen by red-free photography.

This study aimed to compare the outcomes of outpatient and inpatient management of layered hyphema. ⋯ In the authors' predominantly white patient population, close outpatient follow-up of traumatic hyphemas appears to be safe and effective. Hospitalization for hyphema does not appear to decrease the rate of rebleeding. Decreased vision in the setting of traumatic hyphema generally results from comorbidities not affected by inpatient management.

This study aimed to report the long-term outcomes of patients treated with an antibiotic drug combination for Bartonella henselae neuroretinitis. ⋯ B. henselae is a cause of neuroretinitis in cat scratch disease. Compared to historic cases, doxycycline and rifampin appeared to shorten the course of disease and hasten visual recovery. Long-term prognosis is good, but some individuals may acquire a mild postinfectious optic neuropathy.

Comparative Study
Prevalence of uncorrected binocular distance visual acuity in Hispanic and non-Hispanic adults. Results from the HHANES and the NHANES I.
This study aimed to provide a comparative analysis of American population-based prevalence of uncorrected binocular distance visual acuity in Hispanics and non-Hispanics. ⋯ The prevalence of impaired uncorrected binocular distance visual acuity generally is lower in Hispanics than in non-Hispanic whites.
