Fine-needle diathermy plus bevacizumab for corneal blood vessel growth

Official title: Evaluation of Combined Fine-needle Diathermy and Subconjunctival Bevacizumab Injection in the Treatment of Corneal Neovascularization

Run by HoChiMinh City Eye Hospital · NCT07642960 · Data updated 2026-11-12

This study tests whether combining fine-needle diathermy with a bevacizumab injection under the conjunctiva can reduce corneal neovascularization and is safe in adults.

Is this trial a fit for you?

Likely a good fit

Adults with stable CNV involving at least one corneal quadrant, who can comply with follow-up visits.

Probably not a fit

Patients with active infection, uncontrolled systemic disease, recent ocular surgery, or contraindications to bevacizumab may not benefit or could be at higher risk.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this interventional trial, adults with corneal neovascularization receive both fine-needle diathermy to occlude abnormal vessels and a subconjunctival bevacizumab injection to curb VEGF-driven growth. Participants undergo baseline and follow-up ophthalmic assessments, including visual acuity, intraocular pressure, slit-lamp exam, corneal photography, and AS-OCT. The goal is to see if the combination can promote regression of neovessels while maintaining safety and tolerability. Eligibility requires stable CNV affecting at least one corneal quadrant, with several exclusion criteria to minimize risk. The study is led by HoChiMinh City Eye Hospital in Ho Chi Minh City, Vietnam, with assessments to monitor adverse events and efficacy.

Why it matters

Potential benefit: If successful, patients could experience reduced corneal neovascularization and potentially improved vision or graft survival in cases where CNV threatens corneal transparency.

How similar studies have gone: Both fine-needle diathermy and bevacizumab have been used separately for CNV; combining them is a logical, but less extensively studied, approach.
