Retinitis Pigmentosa

Presenting Symptom: Visual field constriction. Pathology: Pigmentary retinopathy. Clinical: Although occurring usually as a solitary entity, retinitis pigmentosa may be associated with several systemic hereditary conditions: deafness, cerebellar dysfunction, cerebral dysfunction (Vogt-Spielmeyer disease) or Refsum's disease, where the body accumulates excessive amounts of phytanic acid. Characteristic of retinitis pigmentosa is progressive constriction of the visual field, formation of bone corpuscle-like pigmentation in the retina and severe narrowing of the retinal arteries. The pigmentation and narrow arteries are shown on the nasal side of the disc in the present case which was one of solitary retinitis pigmentosa. Disease/ Diagnosis: Retinitis pigmentosa
