To report the flash visual evoked potential (VEP) findings in children with primary congenital glaucoma (PCG) before and after successful surgical control of the intraocular pressure (IOP). The study enrolled children presenting with PCG to the Ophthalmology Department of Alexandria Main University Hospital in the period between June and December 2019. All study participants were subjected to a standard protocol of examination, to confirm the diagnosis of PCG. The child was then referred for flash VEP testing. Peaks were designated as negative and positive waves in a numerical sequence (N1, P1, N2, P2, N3 and P3). The child was then scheduled for surgery within 1 week of presentation. Postoperative VEP testing was scheduled as soon as feasible and was conducted in the same way as the preoperative VEP testing. The study was conducted on 11 (four right) eyes of eight (five males) children. The mean ± standard deviation of the age of the study children at presentation and at postoperative VEP testing was 3.5 ± 1.6 and 5.1 ± 3.0 months, respectively. The study eyes mean ± standard deviation IOP at presentation and at postoperative VEP testing was 23.0 ± 6.7 and 8.3 ± 2.4 mmHg, respectively (p
