  • A Natural History Observation and Registry Study of Macular Telangiectasia Type 2: The MacTel Study Rochester, Minn.

    The purpose of this study is to develop a Registry of participants with MacTel Type 2 (as confirmed by the Reading Center) who may agree to be contacted for inclusion in future clinical trials. The Registry participants include new participants and participants from the NHO, Genetic I and Genetics II studies who agree to continue to participate. 

    The second objective is to continue to identify whether there is a genetic link associated with MacTel Type 2. All participants who have not previously provided a blood sample will be given the option to provide a blood sample for genetic sequencing.
