An 11-year-old male presented with gradual diminution of vision in the left eye since 2 years. BCVA was 6/6, N6 in the right and 6/36 and N8 in the left eye. Fundus evaluation of both eyes showed well-defined circular lesions at the macula with atrophic changes, vitelliform deposits at the lower edge, and fibrosis at the fovea in the left eye. A translucent white lesion was seen in the superficial retina, without calcification and no evidence of dilated vessels surrounding it measuring 1 DD in size in superotemporal quadrant of the right eye and a vertically elongated translucent lesion with white specks suggestive of calcification above the disc in the left eye [Figure 1]. His father [Figure 2] and paternal grandmother had a history of dry macular degeneration. General examination revealed facial angiofibromas, shagreen patch [Figure 3], and multiple hypomelanotic macules over back and legs. Abdominal scans showed multiple renal angiomyolipomas. Patient was on carbamazepine 300 mg/day for epilepsy and was advised regular follow-ups for both the systemic and ocular conditions.

Swept source optical coherence tomography (SSOCT) shows a hyperreflective prominent Verhoeff's membrane (white arrow) and surrounding subretinal fluid and hypertrophic retinal pigment epithelium (white star) at the fovea suggestive of Stage 4 of BVMD [Figure 4]a and [Figure 4]b.[1],[2] SSOCT through the astrocytoma showed an inner retinal mass lesion compressing on the outer retina with central full-thickness involvement having a moth-eaten appearance [Figure 4]c and [Figure 4]d.[3] Magnetic resonance imaging brain showed cortical and subependymal tubers and ventricular bands [Figure 5]a. EOG showed an abnormal Arden's ratio (left eye: 1.151; right eye: 1.141) [Figure 5]b.

  Discussion Top


Tuberous sclerosis has an incidence of about 1/10,000 population,[4] whereas Best's dystrophy has a reported incidence of 1–9/100,000.[1] The diagnosis of BVMD was established clinically and confirmed by abnormal Arden's ratio on EOG and the presence of macular lesions in the father and grandmother.[3] A diagnosis of retinal astrocytic hamartoma with TSC was established due to the presence of the major criteria as described by Northrup and Krueger.[5]


  Conclusion Top


The report presents an unusual combined presentation of both autosomal dominant disorders in a patient with clinical features classical of both TSC and Best's dystrophy.
