Long-term evaluation of patients with Best's vitelliform dystrophy

Area of Science:

• Ophthalmology
• Genetics
• Retinal Diseases

Background:

• Best's dystrophy is an inherited retinal condition.
• It affects central vision due to macular degeneration.

Purpose of the Study:

• To track the progression of Best's dystrophy.
• To identify factors influencing visual acuity decline.

Main Methods:

• Longitudinal study of 91 patients with Best's dystrophy.
• Follow-up of 54 individuals over five years.
• Staging based on macular changes and visual acuity assessment.

Main Results:

• Eyes with vitelliform or pseudohypopyon lesions progressed to atrophic stages.
• Visual acuity declined after age 40, especially with atrophic maculae or scars.
• Significant vision loss occurred in 19% of patients with advanced macular changes over 8-10 years.

Conclusions:

• Macular changes in Best's dystrophy can progress over time.
• Advanced stages are associated with decreased visual acuity.
• Early detection and monitoring are crucial for managing vision loss in Best's dystrophy.
