Pigmented viral-associated conjunctival carcinoma.

A 54-year-old African-American woman developed a pigmented papillary squamous cell carcinoma in the palpebral and bulbar conjunctiva of the right eye in areas that received no sun exposure. In situ hybridization performed on the tumor showed human papilloma virus 16. The left eye showed a pedunculated nonpigmented conjunctival dysplasia.

A survey of patterns of physician hygiene in ophthalmology clinic patient encounters.

Purpose: This study examined physician hygiene patterns in the eye clinic of a major medical center to assess compliance with recommended practice patterns to avoid nosocomial infection during patient encounters.

Methods: One hundred ophthalmology resident-patient encounters were observed anonymously by the authors. Examining physicians were evaluated in handwashing between patients, cleaning and disinfecting of tonometer tips after each use, and recapping of diagnostic drop bottles after each use.

The effect of variably tinted spectacle lenses on visual performance in cataract subjects.

Purpose: A body of clinical and laboratory evidence suggests that tinted spectacle lenses may have an effect on visual performance. The aim of this study was to quantify the effects of spectacle lens tint on the visual performance of 25 subjects with cataracts.

Methods: Cataracts were scored based on best-corrected acuity and by comparison with the Lens Opacity Classification System (LOCS III) plates.

Effect of variable tinted spectacle lenses on visual performance in control subjects.

Purpose: To evaluate quantitatively the effects of tinted spectacle lenses on visual performance in individuals without visual pathology.

Methods: Twenty-five subjects were assessed by measuring contrast sensitivity with and without glare. Gray, brown, yellow, green, purple, and blue lens tints were evaluated.
