Retinal vein occlusion (RVO) management has advanced with new diagnostics and intravitreal treatments. This review summarizes clinical, diagnostic, and therapeutic aspects of RVO, citing evidence levels.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Vascular Disorders
Background:
- Retinal vein occlusion (RVO) is a leading cause of vision loss, second only to diabetic retinopathy.
- Recent advancements in diagnostic imaging and intravitreal therapies have significantly improved RVO management and outcomes.
Purpose of the Study:
- To provide a comprehensive review of the clinical, diagnostic, and therapeutic landscape of Retinal Vein Occlusion (RVO).
- To summarize current evidence supporting various treatment modalities for RVO.
Main Methods:
- Systematic literature review of clinical trials and observational studies published over the last 30 years.
- Searches conducted across major databases: MEDLINE, EMBASE, Current Contents, and Cochrane Library.
- Inclusion of evidence grading for all discussed treatments based on the US Preventive Task Force Ranking System.
Main Results:
- New diagnostic tools like spectral domain optical coherence tomography enhance RVO assessment.
- Intravitreal treatments, including vascular endothelial growth factor inhibitors and steroids, have transformed RVO prognosis.
- Evidence levels for different therapeutic interventions are systematically presented.
Conclusions:
- Modern diagnostic and therapeutic strategies have significantly improved the outlook for patients with Retinal Vein Occlusion.
- A thorough understanding of clinical, diagnostic, and evidence-based therapeutic options is crucial for optimal RVO patient care.
