Long Term Management of Peripheral Avascular Retina in Retinopathy of Prematurity Evaluated by Fundus Fluorescein Angiography.

Not applicable Interventional Assiut University · NCT06044181

This study is trying to understand how the lack of blood vessels in the eyes of premature infants with retinopathy of prematurity affects their vision as they grow up.

What this trial studies

This study focuses on understanding the long-term effects of persistent avascular retina in infants who have experienced retinopathy of prematurity (ROP). It aims to explore the natural history of peripheral nonperfusion and vascular abnormalities using advanced imaging techniques like ultrawide-field fluorescein angiography. The study will include infants with a history of ROP, both treated and untreated, to assess the structural and functional implications of these vascular anomalies. By examining these conditions, the research seeks to clarify the risks associated with persistent avascular retina and its potential impact on vision.

Who should consider this trial

Good fit: Ideal candidates include infants with persistent peripheral avascular retina who are being followed up until 18 months of age, including those with regressed ROP and those treated for threshold ROP.

Not a fit: Patients with previous laser therapy, advanced stages of ROP (stage 4 or 5), or other significant ocular pathologies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of visual outcomes in infants with retinopathy of prematurity.

How similar studies have performed: While the study addresses a known condition, the specific focus on persistent avascular retina and its long-term implications is relatively novel and has not been extensively tested in prior studies.
