Retinitis pigmentosa and congenital toxoplasmosis: a rare coexistence.

We describe a previously unreported co-existence of retinitis pigmentosa and congenital toxoplasmosis. An eight year old male presented to our center with complaints of decreased night vision. Fundus evaluations in both the eyes demonstrated features typical of retinitis pigmentosa. There were well-defined punched out healed chorio-retinal scars suggestive of congenital toxoplasmosis. On the basis of history, clinical findings and reduction of a and b wave amplitudes on scotopic and photopic electroretinograph, a diagnosis of retinitis pigmentosa with congenital toxoplasmosis was made. Retinitis pigmentosa may co-exist with congenital toxoplasmosis that may affect the patient's overall ocular morbidity and visual acuity.

Recurrent Salzmann's nodular degeneration: report of two cases and review of literature.

Recurrence of Salzmann's nodular degeneration following corneal transplantation is uncommon. The earlier reports of recurrence of Salzmann's degeneration were based on clinical evidence. We report two histopathologically proven cases of recurrence of Salzmann's nodular degeneration following keratoplasty; one recurring after lamellar keratoplasty and the other following penetrating keratoplasty. Two male patients (40 yrs and 24 yrs) presented to us with a clinical picture of Salzmann's nodular degeneration. One patient had undergone lamellar keratoplasty in both eyes for Salzmann's degeneration, 22 years ago. A repeat lamellar keratoplasty was performed in the right eye (7.5 mm/8 mm). In the other patient, penetrating keratoplasty was performed in the left eye, 6 years ago for the same. Lamellar keratoplasty was performed in the left eye (8 mm/8 mm). The histopathologic evaluation of the host button in both the cases, showed features very much suggestive of a recurrence of Salzmann's nodular degeneration.
