H36.813

Clinical Causes: Sickle cell disease, a hereditary blood disorder characterized by abnormal hemoglobin that causes red blood cells to become rigid and shaped like sickles. Genetic factors influencing the severity and manifestation of sickle-cell disease. Blood vessel damage caused by the sickled red blood cells obstructing blood flow in the retinal vessels.

Key Symptoms: Often asymptomatic in the early stages, with no noticeable changes in vision. Possible mild blurring of vision as the disease progresses. In some cases, floaters or dark spots may be observed due to bleeding or damage within the retina. Gradual decrease in vision if late-stage changes occur.

Diagnosis Path: Dilated fundus examination to visualize retinal blood vessels and detect characteristic changes. Ophthalmoscopy to assess the extent of retinal involvement. Retinal imaging techniques such as fluorescein angiography to identify areas of blood vessel blockage, leakage, or nonproliferative changes. Optical coherence tomography (OCT) for detailed cross-sectional imaging of the retina. Review of the patient’s medical history, particularly sickle cell disease diagnosis.

Treatment Protocols: Regular eye examinations to monitor retinal changes over time. Laser therapy may be considered in advanced cases to reduce the risk of progressing to proliferative stages. Blood transfusions or medications to reduce sickling episodes and improve blood flow, indirectly benefiting retinal health. Prompt treatment of any retinal bleeding or complications as they arise. Coordination with healthcare providers managing sickle cell disease for comprehensive care.
