  • Comparison of the efficacy of vitrectomy combined with complete internal limiting membrane peeling and fovea-sparing internal limiting membrane peeling for high myopia macular foveoschisis

    ObjectiveTo observe and compare the outcomes of vitrectomy (PPV) combined with complete internal limiting membrane (ILM) peeling and fovea-sparing ILM peeling for the high myopic foveoschisis (MF).MethodsA retrospective case study was performed. From June 2016 to June 2018, 31 eyes of 31 patients with high myopic MF diagnosed in Department of Ophthalmology of Central Theater Command General Hospital were included in the study. There were 9 males and 22 females, who were monocular. The mean age was 57.55±9.45 years. All patients underwent BCVA, diopter, spectral domain OCT and axial length measurement. Snellen visual acuity chart was used for BCVA examination, and which was converted into logMAR visual acuity. According to the surgical method, patients were divided into PPV combined with ILM complete removal group (group A) and PPV combined with retained fovea ILM group (group B), which were 16 patients (16 eyes) and 15 patients (15 eyes ), respectively. The mean logMAR BCVA was 1.03±0.33 in group A and 1.11±0.35 in group B. The mean CFT was 596.51±196.69 μm in group A and 578.33±200.18 μm. There were no statistically significant differences in age (t=0.649, P=0.527), AL (t=-0.639, P=0.533), logMAR BCVA (t=-0.368, P=0.718), CFT (t=0.228, P=0.823) and MF type (P=0.576) between the two groups. The mean follow-up time after operation was 18.65±5.15 months. At 7 d, 1, 3, 6 and 12 months after surgery, and at the last follow-up, the same equipment and methods for relevant examinations. The changes of BCVA, CFT, macular hole and other complications were compared between the two groups. Comparison of BCVA and CFT between the two groups before and after operation was performed by paired t test. The count data were compared by using Fisher exact probability method.ResultsAt the last follow-up, MF was completely restored in 27 eyes (87.1%) of 31 eyes, partially restored in 4 eyes (12.9%). The mean logMAR BCVA of group A and Group B was 0.67±0.24 and 0.64±0.21, respectively. The average CFT was 126.25±36.61 μm and 134.27±25.29 μm, respectively. Compared with pre-operation, BCVA was obviously improved in both groups (t=6.630, 9.260; P=0.000, 0.000), CFT was significantly decreased in both groups (t=10.206, 8.799; P=0.000, 0.000). There were no statistically significant differences in logMAR BCVA and CFT between the two groups (t=0.156, -0.924; P=0.878, 0.371). In group A, full-thickness macular hole occurred in 1 eye (6.3%), while no macular hole occurred in group B. There was no significant difference in macular hole incidence between two groups (χ2=0.969, P=0.516). No intraocular hemorrhage, endophthalmitis and other complications occurred during the follow-up period.ConclusionsPPV combined with ILM peeling or fovea-sparing ILM peeling is effective in the treatment of high myopic MF. Both may contribute to improved MF closure rate and BCVA.

  • Efficacy of scleral buckling for rhegmatogenous retinal detachment with subretinal proliferation

    ObjectiveTo observe the effect of scleral buckling surgery (SB) in the treatment of rhegmatogenous retinal detachment (RRD) with subretinal hyperplasia (SRP). MethodsA retrospective case study. From January 2016 to December 2018, 31 patients with old RRD with SRP who were treated with SB in Department of Ophthalmology, Central Theater Command General Hospital were included in the study. There were 18 males with 20 eyes and 13 females with 15 eyes. Age was (26.5±8.7) years. The course of disease was (12.6±10.3) months. The best corrected visual acuity (BCVA) test was performed using the international standard visual acuity chart, which was converted to logarithm of the minimum angle of resolution (logMAR) visual acuity at the time of recording. Retinal detachment ranges ≤2, >2-<3, ≥3 quadrants were 10 (28.6%, 10/35), 20 (57.1%, 20/35), and 5 (14.3%, 5/35) eyes, respectively. All affected eyes were treated with SB. Among them, 22 eyes (63.0%, 22/35) underwent local Scleral buckling, 11 eyes (31.4%, 11/35) underwent combined encircling buckle, and 2 eyes (5.7%, 2/35) underwent encircling buckle alone. Subretinal fluid drainage was performed in 33 eyes (94.3%, 33/35). The mean follow-up time was 18.2 months. Relevant examinations were performed with the same equipment and methods before operation to observe BCVA and retinal reattachment. Paired sample t test was used to compare logMAR BCVA before and after operation. ResultsAt the last follow-up, retinal reattachment occurred in 32 eyes (91.4%, 32/35) of 35 eyes. The retina did not reset in 3 eyes (8.6%, 3/35). logMAR BCVA of affected eye was 0.67±0.29 (finger counting-1.0). The difference of logMAR BCVA before and after operation was statistically significant (t=5.133, P=0.036). In 35 eyes, visual acuity improved, stabilized and decreased in 19 (54.3%, 19/35), 13 (37.1%, 13/35) and 3 (8.6%, 3/35) eyes, respectively. Ten months after surgery, the silicone tape was exposed and infected 1 eye. After the silicone tape was removed, the infection subsided and the retina was in place. There were no intraocular hemorrhage, vitreoretinal impaction, endophthalmitis and other complications during and after operation. ConclusionSB treatment of RRD with SRP can achieve good retinal reposition and improve visual acuity to some extent.
