What is the best to assess macular edema?

• OCT angiography

• Fundus photography

• SD-OCT

• Fluorescein angiography

What is most common anterior complication of CRVO?

• Neovascular glaucoma

• Vitreous hemorrhage

• Retinal traction

• Macular edema

1. What is not the pathogenesis of Retinal Venous Occlusion?

• 1. Endothelial injury

• Presence of anti-VEGF

• Venous stasis

• Hypercoagulability

Which of the following best describes the mechanism of action of Bevacizumab (Avastin) when used in intravitreal injections for Central Retinal Vein Occlusion (CRVO)?

• It reduces intraocular pressure

• It promotes retinal vascular regeneration

• It inhibits VEGF (Vascular Endothelial Growth Factor) and reduces abnormal blood vessel growth

• It directly repairs damaged retinal tissue

Which of the following is a primary goal of treatment for macular edema in CRVO?

• Increasing intraocular pressure

• Inducing retinal hemorrhages

• Reducing inflammation in the optic nerve

• Decreasing macular edema and improving visual acuity

What is a common cause of vision impairment in patients with Central Retinal Vein Occlusion (CRVO)?

• Optic nerve damage

• Macular edema

• Retinal hemorrhages

• Vitreous detachment

1. What is the primary difference between Pro Re Nata (PRN) and Treat and Extend (T&E) regimens for intravitreal injections in retinal diseases?

• PRN involves injections at fixed intervals, while T&E relies on monitoring for disease activity

• PRN involves extending the treatment intervals over time, while T&E relies on a fixed injection schedule

• PRN is a proactive approach, while T&E is a reactive approach to treatment

• PRN and T&E are two different names for the same treatment approach

How should patients be monitored during Bevacizumab treatment for CRVO?

• Monthly eye exams with visual acuity testing

• Annual blood tests

• Quarterly dental check-ups

• Weekly weight measurements

How often is Bevacizumab typically administered in the initial phase of CRVO treatment?

• Every month

• Every 3 months

• Every 6 months

• Once a year

1. In CRVO management, Bevacizumab is often used as an off-label treatment. What does "off-label" mean in this context?

• It is used for a different medical condition than its FDA-approved indication

• It is used without any medical supervision

• It is used exclusively for pediatric patients

• It is used as a first-line treatment
