Assessment of visual function in institutionalized elderly patients.

Objective: To describe the visual function and ocular health of frail elderly patients institutionalized in a tertiary care university-affiliated geriatric hospital.

Design: Retrospective file review.

Setting: A university-affiliated geriatric hospital.

RGC sensitivity to mild systemic hypoxia.

Purpose: Systemic hyperoxia, hypercapnia, and hypoxia are known to alter retinal perfusion. The effects such experimentally induced systemic blood gas perturbations have on inner neuroretinal function in humans were examined.

Methods: Twenty healthy adults participated in each of three test sessions.
