NCT07690800

Brief Summary

This prospective interventional cohort study evaluates the outcomes of intravitreal ranibizumab injection in patients with diabetic vitreous hemorrhage secondary to proliferative diabetic retinopathy. The study aims to assess the effectiveness of ranibizumab in improving visual acuity, promoting vitreous hemorrhage clearance, reducing the need for pars plana vitrectomy, and evaluating treatment-related safety. Eligible adult patients with diabetic vitreous hemorrhage will receive intravitreal ranibizumab according to the study protocol and will be followed for 3 to 6 months with serial ophthalmic examinations. Outcome measures include changes in best-corrected visual acuity, vitreous hemorrhage severity, treatment-related complications, and the proportion of patients requiring vitrectomy. Panretinal photocoagulation may be performed when adequate retinal visualization is achieved.

Outcome Measures

Primary Outcomes (1)

  • Change in Best-Corrected Visual Acuity (BCVA)

    Change in BCVA from baseline to the end of follow-up, measured using Snellen visual acuity and converted to logMAR for statistical analysis.

    Baseline through 6 months

Secondary Outcomes (1)

  • Need for Additional Ranibizumab Injections

    Baseline through 6 months

Study Arms (1)

Intravitreal Ranibizumab

EXPERIMENTAL

Participants with diabetic vitreous hemorrhage secondary to proliferative diabetic retinopathy receive intravitreal ranibizumab (0.5 mg/0.05 mL). Reinjection may be performed at least one month after the initial injection if clinically indicated. Participants are followed for 3 to 6 months to assess visual acuity, vitreous hemorrhage clearance, treatment-related adverse events, and the need for pars plana vitrectomy. Panretinal photocoagulation may be performed when adequate fundus visualization is achieved.

Drug: Ranibizumab

Interventions

Ranibizumab (0.5 mg/0.05 mL) is administered by intravitreal injection under aseptic conditions. Before injection, topical anesthetic and 5% povidone-iodine are applied. The injection is performed using a 30-gauge needle through the inferotemporal pars plana approximately 4 mm posterior to the limbus. Additional injections may be administered after at least one month according to clinical response.
