Diabetic Retinopathy01:27

Diabetic Retinopathy

65
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...

The Arch of Aorta01:10

The Arch of Aorta

2.2K
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Anatomy of the Eyeball

8.6K
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...

Glaucoma: Overview01:25

Glaucoma: Overview

1.7K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

    Summary

    Pre-retinal arterial loops are rare, but can cause branch retinal artery occlusion. This case highlights the first optical coherence tomography scan of a loop linked to occlusion in a young myopic patient.

    Area of Science:

    • Ophthalmology
    • Retinal Vascular Diseases
    • Medical Imaging

    Background:

    • Pre-retinal arterial loops are uncommon vascular anomalies.
    • Association with retinal arterial occlusion is exceptionally rare, with limited prior case reports.

    Observation:

    • A young myopic male presented with symptoms attributed to a pre-retinal arterial loop.
    • The loop was identified as the cause of a branch retinal artery occlusion.

    Findings:

    • This study documents the first optical coherence tomography (OCT) scan precisely through a pre-retinal arterial loop causing branch retinal artery occlusion.
    • The OCT findings provide detailed structural insights into the mechanism of occlusion.

    Implications:
