A Dosing Study of Intravitreal Bevacizumab for Retinopathy of Prematurity

February 1, 2023 updated by: Nooran Mohammed Abdelhameed Abdelkader, Cairo University

A Dosing Study of Two Different Doses (0.3125mg Versus 0.625mg) Intravitreal Bevacizumab for Type 1 ROP (Retinopathy of Prematurity)

The aim of our study was to determine whether a low dose of 0.3125mg intravitreal bevacizumab is effective in treatment of type 1 ROP as the standard 0.625 mg dose., regarding :

Serum Systemic VEGF levels. Retinal Vascularization.
