Choroideremia (CHM) is a rare inherited disorder whose symptoms mirror a more commonly diagnosed condition called retinitis pigmentosa (RP). Symptoms include:
- Peripheral vision loss, leading to tunnel vision
- Sensitivity to glare, and
- Loss of depth and color perception
Up to 70% of individuals with choroideremia are initially diagnosed with RP. Although the symptoms are similar, the root cause for vision loss is different and the only way to know with 100% certainty which condition you have is through free genetic testing.
Although there are currently no cures for either RP or CHM, once the cause of vision loss is known, promising clinical trial options may be available for patients with either condition which could potentially slow progression or preserve remaining eyesight.
The Choroideremia Research Foundation (CRF) is an international nonprofit organization that supports CHM patients, family members and the medical and scientific communities. For patients and families, we provide:
- Online networking groups
- Virtual education programs
- One-on-one support
- In-person meetings and conferences
- Updates on clinical trials and research
- Research grants for scientists
- Patient advocacy
- Additional vision loss resources
- Information on how to access free genetic testing
