Prevalence of Angle Closure in Caucasian Hyperopes

April 4, 2011 updated by: Assaf-Harofeh Medical Center

Prevalence of Chronic Angle Closure in Caucasian Hyperopic Subjects

The primary purpose of this study is to assess the prevalence of asymptomatic chronic angle closure in high risk Caucasian individuals, namely those with hyperopia. A secondary purpose is to assess whether specific demographic or ocular-anatomic parameters in this population are associated with a higher risk for angle closure.

Study Overview

Status

Detailed Description

Caucasian subjects aged > 40 years with hyperopia will undergo complete eye examination including subjective refraction and gonioscopy. In addition we will measure axial length, anterior chamber depth and lens thickness using ultrasound biometry.
