Medical Care

No treatment exists for vitelliform macular dystrophy (Best disease). Secondary choroidal neovascularization can be managed with direct laser treatment. Treatment with an intravitreal injection of bevacizumab has also been described.[5]

Evaluation of family members is important to identify carriers and individuals with vitelliform macular dystrophy. Both genetic counseling and career counseling are provided.

Consultations

  • Consult a vitreoretinal disease specialist for the initial diagnosis, electrophysiology testing, and family assessment, as well as for the long-term follow-up care of patients to monitor disease progression and choroidal neovascularization.
  • Consult a low vision specialist who can provide specialized equipment to assist individuals who have significant deterioration in visual acuity in both eyes.
  • Occupational counseling is important. Although most patients retain reading vision in at least 1 eye throughout life, visual deterioration can occur, particularly beyond age 40 years. This knowledge may influence the choice of career.

Classic egg-yolk appearance in the second (vitelliform) stage of vitelliform macular dystrophy. The 0.5-6 mm diameter yellow or orange lesion results from an accumulation of lipofuscin beneath and within the retinal pigment epithelium. This lesion is usually noted in individuals aged 3-15 years. Visual acuity is most often preserved in the 20/20 to 20/40 range.
The pseudohypopyon (stage 3) lesion is found in the teenage or later years. It results from a break in the retinal pigment epithelium, allowing accumulation of the yellow substance in the subretinal space with the formation of a fluid level. This fluid can shift over 60-90 minutes with positioning.
The atrophic stage (stage 5) may be accompanied by the deposition of pigment or choroidal neovascularization, both of which can lead to visual deterioration.
The scrambled egg appearance of stage 4 results from a deterioration of the uniform cystic lesion noted in stage 2 (egg-yolk appearance). At this point, the visual acuity can begin to worsen.
Adult vitelliform macular dystrophy resembles Best disease, but it can be differentiated by its later age of onset, smaller lesion, and normal electro-oculogram testing.
The fluorescein angiogram of the latter lesion reveals a transmission defect consistent with atrophic changes in the retinal pigment epithelium. This appearance also can be found in the later stages of Best disease.
