Condition Lookup
Category:
Retinal Disorders or Vascular Disorders
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.
