Summary
Treatment frequency for retinal vein occlusion (RVO)-related macular edema (ME) varies significantly in clinical practice. This heterogeneity did not impact long-term visual acuity or retinal thickness outcomes.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Medical Practice
Background:
- Retinal vein occlusion (RVO) can lead to macular edema (ME), impacting vision.
- Understanding treatment patterns is crucial for managing RVO-ME.
- Current clinical practice shows varied anti-VEGF injection frequencies.
Purpose of the Study:
- To characterize anti-VEGF treatment patterns for RVO-ME in routine clinical practice.
- To assess the impact of these treatment patterns on long-term visual acuity and retinal thickness.
Main Methods:
- Retrospective study of 365 eyes with RVO-related ME (2003-2020).
- Analysis of treatment intervals and factors influencing them.
- Subgroup analysis comparing outcomes across different injection intervals.
Main Results:
- Significant heterogeneity in anti-VEGF injection frequency observed for both branch RVO (BRVO) and central/hemi-RVO (CRVO/HRVO).
- Age, diabetes, and baseline central subfield thickness (CST) predicted maintenance injection intervals (MII).
- No significant differences in best-corrected visual acuity (BCVA) or CST at 12 and 24 months across different MII groups.
Conclusions:
- Anti-VEGF treatment frequency for RVO-ME exhibits considerable variation in clinical practice.
- Despite treatment heterogeneity, long-term visual and anatomical outcomes were comparable across different injection intervals.

Open Angle Glaucoma: Treatment
524
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Varicose Veins II: Diagnostic Studies and Interprofessional Care
23
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Venous Thrombosis III: Interprofessional Care
16
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Angle Closure Glaucoma: Treatment
619
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
26
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Regulation of Angiogenesis and Blood Supply
2.7K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
