Ocular findings in homozygous sickle cell disease in Nigeria.

ABSTRACT

We report the ocular findings in 124 Nigerians with homozygous sickle cell disease. None had ocular symptoms. In order of frequency conjunctival vessel anomalies, tortuosity of the major retinal vessels and chorioretinal scars were found. The resemblance of sickle cell chorioretinal scars to toxoplasmic choroiditis is remarkable and should lead to the exclusion of sickle cell disease whenever such lesions are encountered. Angioid streaks, retinitis proliferans, retinal detachment and arteriovenous fans were not observed.
