Les bêtathalasso-drépanocytoses pourvoyeuses de rétinopathies ischémiques graves

The authors in this study intended to demonstrate that S-beta thalassemia can lead to severe ocular hemorrhagic risks, as is true of the sickle cell form. Both forms are also comparable in terms of the risk of aseptic necrosis of the femoral head. Out of the 18 patients studied, 13 (72.2%) had sickle cell retinopathy. Three of 13 patients had already developed new vessels and risked intravitreous hemorrhage. The authors recommend that more vigilance be mounted for the detection of S-beta thalassemia so as to benefit from rigorous and systematic follow-up and early treatment. Retinal argon laser photocoagulation is only effective if a clear diagnosis is made early.
