title: [A case of a retinitis pigmentosa and asteroid hyalosis].
abstract: Asteroid hyalosis is a rare degenerative condition of the vitreous. No causal relationship between retinitis pigmentosa and asteroid hyalosis has been established. We report a case of a 65-year-old male admitted for progressive hemeralopia. Visual acuities were 2/10e in the right eye and 4/10e in the left eye. Ophthalmic examination revealed a large number of asteroid and refringent bodies, a typical retinitis pigmentosa with a cystoid macular oedema confirmed by fluorescein angiography. Electrodiagnostic testing revealed an altered electroretinogram. Visual fields showed a typical generalized constriction. We discuss the clinical aspects and physiopathogenic mechanisms of this rare association through this case and other cases found in the literature.
