“…Although the disease can affect the vasculature of any part of the body, retinopathy is potentially damaging and may lead to visual impairment. Most of the clinically evident retinal vascular changes affect the peripheral retina and are broadly classified into non-proliferative and proliferative sickle cell retinopathy (PSR) 2. Posterior ischaemic chorioretinal changes such as central and branch retinal artery occlusion, macular infarction and ischaemic optic neuropathy have also been reported 3…”

“…Não parece haver consenso com relação à idade apropriada para início do tratamento da retinopatia proliferativa no paciente portador de anemia falciforme, uma vez que existem relatos controversos sobre a eventual resolução espontânea do quadro (11) , que, no entanto, não foi observada por outros autores (9) .…”

“…A retina periférica e a mácula parecem ser os locais mais suscetíveis à oclusão vascular, onde as lesões são mais evidentes e destrutivas, podendo ocasionar cegueira (11)(12)(13) .…”

“…The pathophysiology of sickle cell disease is not limited to ab normalities of erythrocytes; its clinical manifestations are related to processes and complex metabolic pathways that include endothelial activation, inflammation, nitric oxide bioavailability, oxidative stress and regulation of the adhesiveness of several types of blood cells (2) . The Hb molecule is composed of two alpha and two beta po lypeptide chains.…”

“…The multifaceted nature of sicklecell disease allows the development of vascular occlusion to be arrested at multiple points, including HbS polymerization, erythrocyte density and cellcell interactions. The emerging treatment options that can be employed to improve tissue perfusion in these patients include (2) …”
