Retinitis pigmentosa in association with acromegaly: a case report.

Retinal abnormalities, unrelated to visual pathway compression, in acromegalic patients were originally described by Small in 1972 (Smail JM. Primary pigmentary degeneration of the retina and acromegaly in a case of pituitary adenoma. Br J Ophthalmol 1972; 56: 25-31). He illustrated a case of primary pigmentary degeneration of the retina occurring in a patient with a chromophobe adenoma of the pituitary gland. To the best of our knowledge this remains the sole, published case of this association. We report on two male patients, with an acromegalic appearance, one caused by a pituitary adenoma, the other associated with a Rathke's cleft cyst, presenting to our department of ophthalmology with the clinical picture of pigmentary degeneration of the retina.
