7 year old female child who is a known case of tuberous sclerosis was referred for ophthalmological evaluation. Child has history of seizures and low performance at school. General examination revealed ash leaf macules and shagreen patch. Visual Acuity OU 6/6. IOP by NCT was 12 OU.
Colour vision and field examination were normal. Anterior segment examination of both eyes were normal. Dilated fundus examination revealed a clear media blurring of margins of the optic disc. Spontaneous venous pulsations were seen.Autoflourescence pattern of disc was noted. B scan revealed an hyperechogenic lesions of both optic nerves with posterior shadowing which was suggestive of an Astrocytoma.
MRI revealed calcified subependymal nodules and subcortical radiating band like hyperintensities suggestive of tuberous sclerosis complex. We are presenting this case for its rarity. Retinal or Optic nerve astrocytoma is frequently associated with tuberous sclerosis. Treatment is usually not required.
