Registry Study of Macular Telangiectasia Type 2

(IRB#: IRB_00045548)

Macular telangiectasia type 2 (MacTel Type 2) is an uncommon eye disorder causing slow vision loss in middle age. The macula is the central part of the retina, which lines the back of the eye like the film of a camera. The macula allows central vision, which is vital for reading and driving tasks. Telangiectasia refers to dilated, leaky blood vessels. There are no approved treatments to prevent the loss of vision that occurs in many, but not all, eyes with MacTel Type 2. This study aims to create a registry of persons with MacTel Type 2, their immediate family members, healthy volunteers, and persons with related disorders. This registry will enable clinicians and scientists to understand better the characteristics of MacTel Type 2. Information learned may help find a way to prevent or treat this eye condition. People in the study will attend one visit to the clinic for medical, ocular (eye), and medication histories, genetics blood draw, visual acuity testing, comprehensive eye exam, and ocular imaging. People will be invited to register in the MacTel Project Contact Database. Registration is done online and is voluntary. Contact information will be collected to provide new information or treatments learned about MacTel if a person chooses to register.
