Abstract Details

Purpose:

To evaluate retinal and visual changes after cataract surgery in patients with highly myopic retinoschisis.

Setting:

Department of Ophthalmology, Six People? s Hospital Affiliated of Shanghai Jiaotong University, Shanghai, China.

Methods:

This retrospective study included 35 eyes of 28 patients with highly myopic retinoschisis that received phacoemulsification and intraocular lens implantation. The preoperative and postoperative best-corrected visual acuity (BCVA) was recorded. The minimal foveal thickness of retina (MFT) and maximum neuroretinal thickness (MNRT) were measured by optical coherence tomography (OCT).

Results:

The mean follow-up period was 8.4 months ± 4.3 (SD). Compared to the mean preoperative BCVA of 0.88 ± 0.73 logMAR, the postoperative BCVA was improved at 1 week (0.29 ± 0.31 logMAR; P < 0.0001), 1 month (0.28 ± 0.30 logMAR; P < 0.0001), 3 months (0.27 ± 0.36 logMAR; P < 0.0001), and 6 months after surgery (0.29 ± 0.32 logMAR; P <0.0001). The MFT and MNRT were not significantly different from the preoperative level at each postoperative visit (P > 0.05). Eyes with non-foveal retinoschisis had significantly better BCVA than those with foveal retinoschisis throughout the follow-up period of 1 week, and 1, 3, and 6 months ?P = 0.049?0.016?0.040, and 0.045?respectively). Compared with preoperative values, the postoperative logMAR BCVA of foveal retinoschisis eyes without macular holes was positively correlated with MFT at 1, 3, and 6 months after surgery (P = 0.017, 0.025, and 0.008, respectively). The postoperative MFT and MNRT in the 19 eyes combined with vitreoretinal traction were not significantly different from baseline at each visit (P > 0.05). Changes in MFT and MNRT from baseline were not significantly associated with accumulated energy complex parameter (AECP) or axial length (P > 0.05).

Conclusions:

Visual acuity improved and retinal morphology remained stable after phacoemulsification in patients with highly myopic retinoschisis. Postoperative BCVA depended mainly on the location and degree of the retinoschisis. FINANCIAL DISCLOSURE?: No
