What is Best Vitelliform Macular Dystrophy

Best Vitelliform Macular Dystrophy (BVMD) is a rare genetic eye disorder that affects the macula, the central part of the retina responsible for sharp central vision. It is also known as Best disease or vitelliform macular degeneration.

BVMD typically begins in childhood or adolescence and progresses slowly over time. The condition is characterized by the accumulation of lipofuscin, a fatty yellow pigment, in the macula. This buildup can lead to the formation of yellowish lesions called vitelliform deposits, which can impair central vision.

Symptoms of BVMD may include blurred or distorted central vision, difficulty reading or recognizing faces, and decreased color perception. Some individuals may also experience a decline in visual acuity.

Diagnosis of BVMD involves a comprehensive eye examination, including visual acuity tests, dilated fundus examination, and imaging techniques such as optical coherence tomography (OCT) and fundus autofluorescence.

Treatment for BVMD is currently limited, as there is no cure for the condition. However, regular monitoring of vision and eye health is important to detect any changes or complications. In some cases, low vision aids and visual rehabilitation techniques can help individuals manage their visual impairment.

If you suspect you or a loved one may have BVMD, it is crucial to consult with an ophthalmologist for a proper diagnosis and guidance on managing the condition.
