Intravitreal ranibizumab injection for choroidal neovascularization in Strümpell-Lorrain Syndrome.

Strümpell-Lorrain syndrome, or hereditary spastic paraplegia is a genetic disease of the central nervous system affecting the spinal cord and cerebellum. It represents a clinically heterogenous group of neurodegenerative disorders characterized by progressive spasticity and hyperreflexia of the lower limbs. Ocular abnormalities include keratitis, macular pigmentary abnormalities, juxtafoveolar retinal telangiectasis and choroidal neovascularization. We report the first case of choroidal neovascularization associated with Strüpell-Lorrain syndrome treated successfully with intravitreal ranibizumab injection.
