Background

Condition Lookup

Number of Conditions: 3

Branch Retinal Vein Occlusion (BRVO)

Specialty: Ophthalmology

Category: Retinal Disorders or Vascular Disorders

Symptoms:
sudden vision loss; blurred central vision

Root Cause:
Blockage of a retinal vein leads to fluid leakage and swelling.

How it's Diagnosed: videos
Fundus examination, OCT, fluorescein angiography.

Treatment:
Anti-VEGF injections (Aflibercept, Ranibizumab), laser therapy.

Medications:
Anti-VEGF injections (e.g., Ranibizumab , Bevacizumab ), corticosteroids (e.g., Dexamethasone implants).

Prevalence: How common the health condition is within a specific population.
Affects 4–5 in 1,000 adults, more common in those over 50.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
High blood pressure, diabetes, smoking, glaucoma.

Prognosis: The expected outcome or course of the condition over time.
Vision can improve with timely treatment; untreated cases may lead to permanent vision impairment.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Macular edema, neovascularization, secondary glaucoma.

Central Retinal Artery Occlusion (CRAO)

Specialty: Ophthalmology

Category: Retinal Disorders or Vascular Disorders

Symptoms:
sudden, painless vision loss

Root Cause:
Arterial blockage restricts blood flow to the retina, causing ischemia.

How it's Diagnosed: videos
Fundus examination, OCT, fluorescein angiography.

Treatment:
Emergency: lowering intraocular pressure, ocular massage.

Medications:
No proven medications; ocular massage, acetazolamide (to reduce intraocular pressure), and hyperbaric oxygen therapy may be used.

Prevalence: How common the health condition is within a specific population.
Rare; affects 1–2 in 100,000 individuals annually.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Cardiovascular disease, hypertension, smoking, embolism.

Prognosis: The expected outcome or course of the condition over time.
Poor; vision loss is usually irreversible without immediate intervention.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Severe, permanent vision loss; secondary neovascular glaucoma.

Retinal Vein Occlusion

Specialty: Ophthalmology

Category: Retinal Disorders or Vascular Disorders

Symptoms:
sudden vision loss; blurry vision; distorted vision

Root Cause:
Blockage in a retinal vein leads to fluid buildup and vision impairment.

How it's Diagnosed: videos
Fundus examination, OCT, fluorescein angiography.

Treatment:
Anti-VEGF injections, steroid implants, laser therapy.

Medications:
Anti-VEGF injections (e.g., Ranibizumab , Aflibercept ), corticosteroids (e.g., Dexamethasone implants).

Prevalence: How common the health condition is within a specific population.
Second most common retinal vascular disorder; affects older adults.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
High blood pressure, diabetes, smoking, high cholesterol.

Prognosis: The expected outcome or course of the condition over time.
Vision may improve with treatment; untreated cases lead to permanent vision loss.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Macular edema, neovascular glaucoma, secondary vision loss.
