• Tuberous sclerosis complex (TSC) is a multisystem disorder characterized by hamartomatous growths that can occur in almost any organ or tissue.

• Tuberous sclerosis (Bourneville's disease) is an autosomal dominant disorder with a defective chromosome 9.

• The first description of TSC is usually attributed to Bourneville in 18801 and in 1908, Vogt described the classic triad of epilepsy, mental retardation, and adenoma sebaceum (now called angiofibromatosis).

The diagnosis is based on fulfilling:

One major criterion:•Facial angiofibroma•Ungual fibroma•Subependymal hamartoma on brain imaging•At least two retinal hamartomas or

Two minor criteria

•Infantile spasms.

•Hypopigmented skin macules.

•Shagreen patch.

•Bilateral renal angiomyolipoa.

•Cardiac rhabdomyoma.

•First-degree relative with the disease.

•Single retinal hamartoma.

Ophthalmic features associated with TSC can be divided into :

•Retinal

•Non-retinal

Retinal lesions• Retinal lesions are astrocytic hamartomas

“collection of astrocytes”.

Three basic morphological types of retinal hamartomas are described in the literature:

• The relatively flat, smooth, non-calcified, grey, translucent lesion.

• The elevated, multinodular, calcified, opaque lesion resembling mulberries.

• A transitional lesion which has morphological features of both of the previous.

Other retinal findings include:

•Pigmentary disturbance ranging from hyperpigmented areas (probably congenital retinal pigment epithelium hypertrophy) to “punched out” hypopigmented areas at the posterior pole or midperiphery.

• The hamartomas may be richly vascularized.

• They generally do not grow, but over decades some of the lesions may become calcified.

• Visual loss from retinal and optic nerve hamartomas rarely occurs.

• Because growth and change of the fundus lesions are rare, treatment is not indicated.

• Retinoblastoma of the optic nerve and retina is the most important lesion that must be differentiated from the hamartomas seen with tuberous sclerosis.

Non-retinal findings include:

•Angiofibromas of the eyelids.•Coloboma of the iris, lens and choroid.•Strabismus.•Poliosis of eyelashes.•Papilloedema.•Sector iris depigmentation.
