RETINAL DETACHMENT OF REGRESSED RETINOPATHY OF PREMATURITY IN CHILDREN AGED 2 TO 15 YEARS

Purpose: To reveal the clinical features and surgical results of retinal detachment of regressed retinopathy of prematurity (ROP) that occur in the children aged 2 to 15 years. Patients and Methods: The records of patient who had a retinal detachment of a regressed ROP were retrospectively reviewed. Sixteen eyes from 15 patients that required surgical treatments due to retinal detachment of a regressed ROP were included. Results: After treatment of acute phase of ROP, eight eyes showed grade II of cicatricial change and eight eyes showed grade III. We did not find any evidence that the acute stages of ROP and its treatment affect the degree of the cicatricial changes. All eight eyes with grade III of cicatricial ROP showed tractional retinal detachment (TRD) and five of eight eyes (62.5%) with grade II showed rhegmatogenous retinal detachment (RRD). The mean interval between regressed ROP and development of late retinal detachment was 20.7 months (range, 12–61 months) in the TRD group and 85.8 months (range, 33–148) in the RRD group. The mean age at onset of late detachment was 34.1 months (range, 26–73 months) in the TRD group and 98.6 months (range, 45–162) in the RRD group. Anatomical success was achieved at one of five eyes (20%) with RRD and six of 11 eyes (54.5%) with TRD. Compared with the preoperative visual acuity, visual improvement, no change, and decreased visual acuity were achieved, respectively, in two eyes, three eyes, and no eyes in the RRD group and three eyes, six eyes, and two eyes in the TRD group. However, only two of 16 eyes with late retinal detachment achieved a visual acuity of 20/200 or better. Conclusion: Late retinal detachment is the main vision-threatening condition in patients with regressed ROP during childhood. The visual prognoses of these patients are poorer than those with late retinal detachments that occur in adult ROP patients. Therefore, a periodic fundus examination should be performed more frequently during childhood than in adulthood, particularly in nonverbal children.
