Tuberous sclerosis

Description

Tuberous sclerosis is a rare genetic disease of autosomal dominant inheritance. It causes multiple hamartomas that appear in various organs such as the brain, heart, liver, kidneys and eyes. This tumor growth is caused by mutations in the TSC1 and TSC2 genes that code for hamartin and tuberin, proteins that decrease cell proliferation through the mTOR pathway. The diagnosis is clinical and is established through major criteria, such as retinal hamartomas, and minor criteria. mTOR inhibitors (Sirolimus and Everolimus) may decrease the appearance and growth of retinal hamartomas.

Comments

Did you know that the differential diagnosis of retinal hamartomas is with myelination of the nerve fiber layer and with solitary localized retinal astrocytic proliferation (pSCRAP).

Indication

A 25-year-old woman was diagnosed with tuberous sclerosis at 6 months of age and was being followed up in retina clinics for annual control funduscopy. Visual acuity is 1 in both eyes, with no relevant findings in the anterior segment. Multiple astrocytic retinal hamartomas appear in the fundus of the eye in the periphery that do not affect the macula.
