A Natural History Observation and Registry Study of Macular Telangiectasia Type

Overview

About this study

The purpose of this study is to identify persons with MacTel Type 2, and their affected family members to create a registry of persons with MacTel Type 2. This registry will be used to study participants with MacTel Type 2 now and may be used in the future to identify persons to be in a study that may help find a way to prevent or treat this eye condition. We also wish to keep in contact with persons who have been told by their MacTel doctor that they have MacTel Type 2.
