Retinal Vascular Caliber and Macular Telangiectasia Type 2

Abstract

OBJECTIVE: To examine the relationship of retinal vascular caliber to macular telangiectasia (MT) type 2. DESIGN: Case-control study. PARTICIPANTS: Patients with MT aged 18 years and older were identified from Australian sites of the multicenter Macular Telangiectasia Project. Three controls per case were selected from participants of the Australian Diabetes, Obesity and Lifestyle study, matched according to age and diabetes status.
