Purpose
It was aimed to evaluate the incidence of unilateral treatment requiring ROP in the study.
Setting/Venue
The study was set as two centered and retrospective design between January 2019 – March 2021 in Erzincan Binali Yildirim University Faculty of Medicine Department of Ophthalmology, Turkey and Diyarbakir Gazi Yasargil Training and Research Hospital Department of Ophthalmology, Turkey.
Methods
Data of 6214 eyes of 3107 infants were evaluated and recorded. Examination findings were recorded according to the Classification of Retinopathy of Prematurity guideline. The following informations were recorded: gestational age, birth weight, type of delivery, duration of staying in neonatal intensive care unit (NICU) and oxygen therapy, age at the time of diagnosis and treatment (weeks), the location, laterality and type of ROP, the severity of ROP, vascular characteristics of ROP, treatment status, postmenstrual age, treatment modality, and retinal vascular development.
Results
Seven hundred sixty nine (24.8%) of 3107 babies were diagnosed with ROP. Two hundred four eyes of 107 (3.4%) infants were treated for ROP [intravitreal anti VEGF (IVA), laser photocoagulation (LPC) or surgical (pars plana vitrectomy) treatment]. Fifty eyes had aggressive posterior ROP (AP-ROP), 154 eyes had type 1 ROP and 1324 eyes had type 2 ROP at first visit in the study. At first visit, 22 infants had asymmetric ROP. Ten eyes (4.9%) of 10 babies had unilateral treatment requiring ROP. One hundred ninety four eyes (95.1%) of 97 babies have bilateral treatment requiring ROP. There was no significant difference in gestational age, birth weight, type of delivery, duration of staying in NICU and oxygen therapy between two groups.
Conlusions
ROP was highly symmetric between the eyes of infants undergoing ROP screening. When AP-ROP or type 1 ROP develops in one eye and type 2 ROP in the fellow eye, the risk of progression to treatment requiring ROP in the fellow eye are higher in infants with AP-ROP.
