Intravitreal anti-VEGF treatment for retinopathy of prematurity in infants with active adenoviral keratoconjunctivitis

Purpose: To evaluate the results of intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment for retinopathy of prematurity (ROP) in infants with active adenoviral keratoconjunctivitis (AKC).

Material and methods: A retrospective analysis was performed using the medical records of all infants treated with intravitreal injections of anti-VEGF agents during an AKC outbreak previously reported in the literature at a tertiary center for treatment of ROP. The infants were divided into two groups. Group 1 included nine infants (18 eyes) with AKC, while Group 2 included 13 infants (26 eyes) without AKC.

Results: During the AKC outbreak, 22 infants were treated with anti-VEGF agents for treatment-requiring ROP. In all patients in both groups, the ROP and plus disease displayed a significant regression within 2 days after the intravitreal injections. Moreover, no serious complications such as endophthalmitis, retinal detachment, cataract or intravitreal hemorrhage were observed after the treatment and there were no statistically significant differences between the groups in terms of postoperative complications.

Conclusion: Immediate and appropriate intervention is very important in cases of treatment-requiring ROP otherwise it can result in blindness. However, laser treatment for ROP is technically difficult in infants with active AKC. The results of this study showed that favorable outcomes without serious ocular complications could be obtained via intravitreal injections of anti-VEGF agents in infants with active AKC.
