Objective To evaluate the efficacy of orthokeratology combined with monocular partial occlusion and fine training for the treatment of ametropic amblyopia. Methods A prospective study.The data of 86 children with ametropic amblyopia in this hospital from Dec.2016 to May 2018 were analyzed.All cases were randomly divided into two groups, with each group of 43 cases.All cases were partially coverd with a single eye.The control group adopted fine training.The research group underwent orthokeratology combined with fine training, and both groups were treated for 6 months. Results The total effective rate of the research group(97.67%)was higher than that of the control group(81.40%)(χ2=4.468, P=0.035). The best corrected visual acuity (LogMAR) of the research group (0.1±0.01) was better than that of the control group (0.15±0.02) (t=14.663, P=0.000). Visual sensitivity of the research group was higher than that of the control group(t=4.428, P=0.000). The adjustment flexibility and adjustment range of the research group were greater than that of the control group, and the adjustment hysteresis of the research group was less than that of the control group(P=0.000). Conclusion The combination of orthokeratology, monocular partial occlusion and fine training is effective for the treatment of children with ametropic amblyopia.

Objective To compare the calculation accuracy with three different intraocular lens (IOL) diopter formulas for high myopia with cataract. Methods The data of 172 eyes of 172 patients with high myopia with cataract from Feb. 2017 to Nov. 2018 in this hospital were analyzed retrospectively. All cases were divided into 3 groups according to axial length (AL). AL of group A was 26.1-28.0 mm, 28.1-30.0 mm in group B and ≥30.1 mm in group C. The intraocular lens diopter of three groups were calculated with SRK/T, Haigis and Barrett Universal II formulas, respectively. The accuracy of IOL diopter among three formulas were compared in each groups at 1 month postopeeratively. Results The difference of IOL diopter accuracy in group A were not statistically significant among three formulas (P=1.000). The IOL diopter with Barrett Universal II was the most accurate in group B and group C. Barrett Universal II was the highest (70.9%) in eyes with error ≤±0.5 D between actual diopter and expected diopter. The difference was statistically significant among three formulas (χ2=18.801, P=0.000). The difference in percentage of prediction error within ±1.0 D was not statistically significant among the three formulas (χ2=5.007, P=0.082). Conclusion The calculation accuracy of IOL diopter with Barrett Universal II formula is the highest for high myopia with cataract.

Objective To evaluate the role of optical coherence tomographic angiography(OCTA) in anti-vascular endothelial growth factor(VEGF) treating the neovascular age-related macular degeneration(nAMD) and follow-up. Methods Total of 41 eyes of 33 patients with nAMD in the Second People’s Hospital of Zhengzhou from May 2018 to Oct. 2018 were analyzed retrospectively. All cases were treated with intravitreal injection of ranibizumab(IVR). All cases were followed up for 6 months. Results At 6 months after treatment, the OCT and OCTA showed the average central retinat thickness reduced (t=31.454, P=0.000), and CNV flow areas shrinked after IVR(t=4.117, P=0.000). The decrease of CNV flow areas in eyes with dense-network CNV was more obvious than that in loose-network CNV (Z=3.686, P=0.000). Conclusion OCTA is a reliable method to observe dynamically the strutures and quantified the blood flow area of CNV. It is significant in treatment and follow-up evaluation of nAMD.

Objective To analyze the causes of retinal detachment in patients with open ocular trauma after vitrectomy. Methods The clinical data of 129 patients with open ocular trauma underwent vitrectomy from Jul. 2013 to Jul. 2018 were retrospectively analyzed. A total of 114 patients in the non-retinal detachment group and 15 patients in the retinal detachment group were included. The cause of retinal detachment after vitrectomy for open ocular trauma were analyzed. Results There was no significant difference in gender, age or type of injury between the two groups (P>0.05). The factors of postoperative retinal detachment were related to combined with proliferative vitreoretinopathy (PVR), retinal detachment, operation time and intraoperative combined therapy. In the retinal detachment group the incidence of posperative retinal detachment in patients of PVR was higher than that in the non-retinal detachment group (P=0.002). The difference of preoperative incidence of retinal detachment (P=0.032) and later operation time (P<0.001) were statistically significant. The proportion of intraoperative scleral cryotherapy and retinotomy in the retinal detachment group (P=0.020, 0.000) was higher than that in the non-retinal detachment group during the operation.

Objective To evaluate the efficacy of single syringe fluid-air exchange (SSFAE) for the treatment of persistent idiopathic macular hole(IMH) after vitrectomy. Methods The data of 11 eyes of 10 cases with persistent IMH after vitrectomy from Jan.2015 to Aug.2018 at Subei People’s Hospital Affiliated to Yangzhou University were retrospectively analyzed. All cases received SSFAE in outpatient department. The closure rate of macular hole and the changes of visual acuity after SSFAE were evaluated. Results The rate of macular hole closed after the first SSFAE was 63.63% (7/11), 72.72% (8/11) after the second SSFAE and 81.81% (9/11) after the third SSFAE. Conclusion SSFAE is a simple, safe and efficient method for the treatment of persistent IMH after vitrectomy. Key words: Hole, macular; Vitrectomy; Exchange, fluid-air, single syringe

Objective To evaluate the efficacy of vertical chop combined with horizontal chop in hard nuclear cataract surgery. Methods A retrospective study. Total of 86 eyes of 86 patients with senile cataract were randomly divided into two groups, and all nuclear classification ranged from IV to V. Group A, 43 patients, received vertical chop combined with horizontal chop. Group B, 43 patients, received phacoemulsification with high vacuum splitting. The efficacy were compared between the two groups. Results The ultrasonic time (UST) was (67.77±14.68) s of group A and (103.09±44.89) s of group. The cumulative dissipated energy (CDE) was 35.33±12.75 of group A and 41.25±14.35 in group B. The difference in UST and CDE were significant statistically between the two groups (P 0.3 occupied 86.05 % in group A and 67.44 % in group B (P=0.04). The corneal edema at 1 day postoperatively in group A was lower than that in group B, the difference was statistically significant between the two groups (P=0.03). The difference in degree of corneal edema at 7 days after surgery was not statistically significant between the two groups. The corneal endothelial cells (CECs) in 1 month postoperatively was (2 371.30±179.02)/mm2 in group A and (2 157.80±156.46)/mm2 in group B(P<0.01). The loss rate of CECs was (8.73±3.74)% in group A and (15.41±3.54)% in group B(P<0.01). Conclusion Application of vertical nuclear chop combined with horizontal nuclear chop in hard nuclear cataracts surgery is effective.
