Summary
Retinal occlusive disease caused binasal visual field defects in a patient with sickle cell (SC) disease. Advanced imaging confirmed retinal dysfunction, distinguishing it from optic nerve issues.
Area of Science:
- Ophthalmology
- Retinal Vascular Diseases
- Sickle Cell Disease
Background:
- Sickle cell (SC) disease is a genetic blood disorder.
- Retinal vascular complications are common in SC disease.
Observation:
- A 21-year-old male with SC disease presented with binasal visual field defects.
- Initial eye exams and fluorescein angiography were normal.
- Optical coherence tomography (OCT) and multifocal electroretinography (mfERG) showed retinal abnormalities.
Findings:
- Bilateral temporal inner retinal hyperreflectivity on OCT.
- Retinal dysfunction confirmed by mfERG.
- Development of macular arteriolar occlusive disease weeks later.
Implications:
- This case highlights rare simultaneous bilateral macular occlusive events in SC disease.
- OCT and mfERG are crucial for differentiating retinal from optic nerve pathology.
- Early diagnosis of retinal occlusive disease is vital for vision preservation in SC patients.

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
