Abstract:
A 12-year-old girl with a translucent, partially calcified retinal mass in the posterior pole surrounded by a rim of pigment epithelial changes and chorioretinal atrophy was diagnosed as having retinocytoma. The patient received a single treatment of transpupillary thermotherapy at the slit lamp to prevent malignant transformation. The dimensions of the lesion and the visual acuity remained unchanged at 3.5 years of follow-up with no further treatment. Retinocytoma is a benign retinal tumor that carries the same genetic implications as retinoblastoma. Regular follow-up is necessary because the tumor can demonstrate malignant transformation.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
