Observation of macular lesion in Best's vitelliform macular dystrophy by scanning laser ophthalmoscope.

Using a scanning laser ophthalmoscope (SLO), the ocular fundus of a patient with Best's vitelliform macular dystrophy was examined. With the argon blue laser, a dark area was seen in the fovea. Areas of weakly bright reflex were seen corresponding to the scrambled-egg lesion observed by ophthalmoscope. With the argon green laser, highly bright spots were observed at the foveola. Intense bright reflex was seen over the scrambled-egg lesion at the posterior pole. The helium-neon laser revealed highly bright patches corresponding to the orderly ring distribution of the yellowish deposits at the posterior pole. The diode laser revealed a mottled appearance with dark and bright patches in the scrambled-egg lesion. SLO provided a morphologic enhancement in the specifically affected layers of the macula in Best's vitelliform macular dystrophy.
