Clinical Causes: Atherosclerosis, which hardens and narrows arteries and veins High blood pressure (hypertension) Diabetes mellitus High cholesterol levels Blood clotting disorders Ocular conditions like glaucoma Age-related changes in blood vessels Smoking and lifestyle factors that impair vascular health

Key Symptoms: Sudden or gradual loss of vision in the affected eye Blurred vision in part of the visual field Visual distortions such as straight lines appearing wavy Dark spots or floaters in the visual field No symptoms in some cases, with the condition discovered during a routine eye exam

Diagnosis Path: Diagnosis typically involves a comprehensive eye examination, including visual acuity testing and dilated fundus examination. Imaging techniques such as optical coherence tomography (OCT) can help visualize retinal structure and detect swelling or hemorrhages. Fluorescein angiography may be performed to assess blood flow and identify occlusion or leaking vessels, enabling precise location of the blocked branch and extent of retinal involvement.

Treatment Protocols: Treatment strategies aim to manage symptoms, prevent complications, and preserve vision. The options may include: - **Laser therapy:** Focal laser treatment can reduce macular swelling and seal leaking blood vessels. - **Intravitreal injections:** Medications such as anti-VEGF agents or corticosteroids are injected into the eye to reduce swelling and improve visual outcomes. - **Management of underlying conditions:** Controlling hypertension, diabetes, and cholesterol levels is vital in preventing progression. - **Regular monitoring:** Consistent follow-up with eye care professionals to assess treatment response and detect potential recurrence. While some cases resolve on their own, others may require medical intervention to optimize visual prognosis.
