Description

<p>[Purpose] To investigate the association of age with the site of retinal break and postoperative visual acuity (VA) in patients with macula-off rhegmatogenous retinal detachment (RRD).</p><p>[Methods] Subjects were 138 eyes (mean age, 51.0 ± 15.4 years) that had received surgery for macula-off RRD and achieved initial reattachment. These eyes were classified by age to group A (under 50 years of age, age of ≤ 50 years) and group B (over 51 years of age, age of ≥ 51 years). The site of retinal break and VA (logMAR equivalent) at postoperative 1 month were studied in both groups. In the 106 eyes which were followed up for 6 months, their VAs at postoperative 3 and 6 months were also examined. </p><p>[Results] Seventy eyes (27 eyes from group A and 43 eyes from group B) had a superotemporal retina break site, 27 eyes had a superonasal break site (9 eyes from group A and 18 eyes from group B), 22 eyes had an inferiortemporal break site (14 eyes from group A and 8 eyes from group B), and 19 eyes had an inferiornasal break site (9 eyes from group A and 10 eyes from group B). Both groups had the largest number of eyes with a superotemporal break site. In addition, patients with younger age significantly had more cases with an inferiortemporal retinal break site. The average VAs at postoperative 1 month were 0.33 ± 0.34 for group A and 0.30 ± 0.30 for group B. No VA difference was observed between both groups. In the 106 eyes that had been followed up for 6 months, the mean VAs at postoperative 3 months were 0.17±0.30 for group A and 0.21±0.29 for group B; and the mean VAs at postoperative 6 months were 0.13 ± 0.28 for group A and 0.14 ± 0.32 for group B. Both groups showed improvement in vision during the period of 6 months. However, no VA difference was seen between both groups at postoperative 1, 3, and 6 months. </p><p>[Conclusion] Postoperative VA did not vary with age in eyes with macula-off RRD. However, more patients with younger age had an inferiortemporal retinal break site.</p>
