What this trial studies

This study evaluates the efficacy and safety of low-dose Conbercept in treating Retinopathy of Prematurity (ROP) in preterm infants. It focuses on determining the optimal effective dose while monitoring for any adverse effects. The study includes infants with specific criteria related to their birth weight and gestational age, and it excludes those with more severe stages of ROP or prior treatments. The goal is to improve outcomes for infants affected by this condition.

Who should consider this trial

Good fit: Ideal candidates for this study are preterm infants weighing 2000 grams or less at birth or born at 32 weeks of gestation or earlier, with bilateral type 1 ROP.

Not a fit: Patients with stage 4 or 5 ROP or those who have previously received treatment for ROP will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the vision outcomes for preterm infants suffering from Retinopathy of Prematurity.

How similar studies have performed: While there have been studies on ROP treatments, the specific use of low-dose Conbercept represents a novel approach that has not been extensively tested.

Exclusion Criteria:

* Preterm infants with stage 4 or 5 ROP in one or both eyes
* Have received any previous surgical or nonsurgical treatment for ROP, including laser photocoagulation, anti-VEGF therapy, vitrectomy
* Have been previously exposed to any intravitreal or systemic anti-VEGF agent (either the patient or the mother during this child's pregnancy)
