PURPOSE
This study is to evaluate the visual prognosis and the frequency of the reoperation according to the refractive power. METHODS: We retrospectively reviewed the medical records of the 19 eyes of 19 patients with retinal detachment caused by macular hole. Patients were classified into 2 groups based on their refractive power, the high myopia group; six patients with -6 diopters or more, and the non-high myopia group; 13 patients with less than -6 diopters. The mean refractive power was -13.4 diopters in high myopia group and+0.19 diopters in non-high myopia group. All patients had vitrectomy and fluid-gas exchange at first operation and silicone oil injection was performed in cases with recurred retinal detachment after 2nd operation. RESULTS: The retina was successfully reattached in all of the 19 eyes and reoperation was needed for achieving retinal reattachment in 4 eyes (21.1%). Three eyes of high myopia group (50%) and one eye of non-high myopia group (7.3%) were reoperated and 2 eyes in high myopia group needed silicone oil injection. Non-high myopia group showed improved visual acuities as compared with preoperative visual acuity (P<0.05, paired t-test). At the last follow up, macular hole was reopened in 3 eyes (15.8%) but the retina was not detached and the 3 eyes showed worse visual acuities than the others with closed macular hole. CONCLUSIONS: Accordingly, the high myopia group had higher incidences of reoperation and worse visual outcome and only one third of the high myopia group needed silicone oil injection, even though these patients may not need silicone oil injection at the first operation. |
