Treatment success of laser therapy for retinopathy of prematurity in referred and non-referred patients

Arq Bras Oftalmol. 2016 Apr;79(2):96-9. doi: 10.5935/0004-2749.20160029.

Abstract

Purpose: Comparison of laser therapy (LT) outcomes in patients with retinopathy of prematurity (ROP) followed up in our clinic and referred from other centers.

Methods: Medical records of 1,856 ROP patients were retrospectively evaluated, and a total of 128 patients who underwent LT were included in the study. The study population was divided into the following two groups: patients who were followed up and treated in our clinic (group 1, N=45) and patients who were referred to our clinic from other centers (group 2, N=83). Data regarding birth weight, sex, gestational age, postnatal treatment time, disease localization, and stage were analyzed and compared between the two groups. Treatment success was defined by anatomic success 6 months after treatment.

Results: Patients in the referred group presented with a more advanced disease (p<0.01), a lower treatment success rate (p=0.01), and a longer time interval between diagnosis and LT (p=0.04).

Conclusions: The treatment success rate of ROP was significantly lower in referred patients because of the potential delay in LT and more advanced disease at the time of treatment initiation.
