Wide-field angiography in retinal vein occlusions

Area of Science:

• Ophthalmology
• Retinal Vascular Diseases
• Medical Imaging

Background:

• Retinal vein occlusion (RVO) is a leading cause of vision loss, second only to diabetic retinopathy.
• Complications include macular edema, neovascularization, and vitreous hemorrhage.
• Ultra-widefield imaging (UWF) offers advanced posterior pole visualization for RVO evaluation.

Purpose of the Study:

• To highlight the utility of UWF imaging in RVO assessment.
• To emphasize the importance of detecting peripheral retinal pathologies in RVO.
• To explore the role of UWF in evaluating retinal non-perfusion.

Main Methods:

• Utilizing ultra-widefield (UWF) imaging to visualize up to 200° of the retina.
• Assessing peripheral retinal pathologies, particularly retinal non-perfusion in RVO.
• Employing techniques like ischemic index and stereographic projection to quantify ischemia.

Main Results:

• UWF imaging enables detection of peripheral retinal non-perfusion, a risk factor for neovascularization.
• Retinal non-perfusion identified via UWF impacts RVO complications like macular edema and neovascularization.
• Non-perfusion assessment influences disease response, visual acuity, and treatment needs.

Conclusions:

• UWF imaging is vital for assessing and managing RVO.
• It plays a key role in quantifying peripheral retinal non-perfusion.
• This enhances understanding of RVO pathology and treatment strategies.
