简要总结
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.
详细描述
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.
