Use of the King-Devick Variable Color Contrast Sensitivity Chart to differentiate stages of age-related macular degeneration.

Objective: This study aimed to determine which colour contrast sensitivity differences exist in early to advanced age-related macular degeneration (AMD) and examine the potential utility of the King-Devick Variable Color Contrast Sensitivity Chart in detecting AMD severity.

Methods And Analysis: A total of 85 participants (144 total eyes) were recruited from multiple clinical practices and enrolled in the study. The control group consisted of 57 healthy eyes.

Long-Term Mortality in Diabetic Patients with Tractional Retinal Detachments.

Purpose: To determine the long-term, all-cause mortality rate of diabetic patients requiring vitrectomy surgery for tractional retinal detachment (TRD).

Design: Institutional review board-approved, retrospective, comparative study.

Participants: Four hundred eyes of 316 patients undergoing vitrectomy surgery from 2005 to 2015.
