Ultrasonography Findings in Eyes With Stage 5 Retinopathy of Prematurity

OpenAlex English

BACKGROUND AND OBJECTIVE: To evaluate ultrasonography outcomes in eyes with stage 5 retinopathy of prematurity (ROP). PATIENTS AND METHODS: Patients with bilateral stage 5 ROP were evaluated retrospectively. Ultrasonography examination was performed in all cases. Patients' demographic features and ultrasonography findings such as axial eye length, funnel configuration, subretinal hemorrhage, anterior loop traction, retinal cyst, and calcification were assessed, and correlations between variables were analyzed. RESULTS: Three hundred eyes of 150 patients were included. Sixty-one patients (40.7%) were female. The mean gestational age was 28.8 weeks ± 2.6 weeks, and the mean birth weight was 1,277 g ± 360 g. The mean axial eye length was 14.7 mm ± 1.8 mm. Two hundred forty-five eyes (81.7%) had closed-closed retinal detachment configuration, 32 (10.7%) had open-closed retinal detachment configuration, 17 (5.7%) had open-open retinal detachment configuration, and six (2%) had closed-open retinal detachment configuration. Subretinal hemorrhage (25.7%), anterior loop traction (24%), retinal cyst (2.3%), and calcification (1.3%) were also observed. CONCLUSION: Closed-closed funnel configuration, reduced axial diameter, and subretinal hemorrhage are associated with poor prognosis, and ocular ultrasonography examination for ascertaining these parameters is very important in cases with stage 5 ROP. In the present study, closed-closed retinal detachment configuration was noted in almost 80% of the cases with stage 5 ROP, which is probably the reason for the surgical failure in these end-stage cases.
