目的：分析高度近视有晶状体眼后房型人工晶状体植入术后孔源性视网膜脱离的临床特征及预后。方法：回顾分析2012年4月至2021年6月中山眼科中心收治的9例(9只眼)行后房型人工晶状体植入术后孔源性视网膜脱离患者的临床特征、手术方式及疗效，随访(4.96±4.78)个月。结果：患者年龄(30.44±20.11)岁，屈光手术至发病时间(32.10±17.80)个月。4例(44.4%)马蹄形裂孔，1例(11.1%)萎缩性裂孔，4例(44.4%)巨大裂孔；9眼裂孔均位于赤道部前，除2眼(22.2%)为单个巨大裂孔，1眼(11.1%)单个马蹄孔，余6眼(66.7%)均有视网膜周边变性区存在；视网膜脱离范围(3.0±1.12)个象限，8例累及黄斑；增殖性玻璃体视网膜病变C级以上4眼。视网膜初始复位率为77.8%，最终视网膜复位率100%。末次随访最佳矫正视力优于术前(P<0.05)。随访期间，2例硅油填充眼发生并发性白内障，4眼发生术后早期高眼压。结论：有晶状体眼后房型人工晶状体植入术前存在的视网膜变性或术后玻璃体牵引的存在可能是孔源性视网膜脱离发生的危险因素。

Objective: To analyze the clinical presentation, surgical management, and outcomes of rhegmatogenous retinal detachment (RRD) in patients with high-myopia corrected by posterior chamber phakic (PCP) intraocular lens (IOL) implantation. Methods: Nine eyes of 9 patients in whom RRD developed after PCPIOL implantation from April 2012 to June 2021 in Zhongshan Ophthalmic Center were retrospectively studied. Mean follow-up after retinal detachment surgery was (4.96±4.78)months. Results: Mean patient age was (30.44±20.11) years old. RRD occurred (32.10±17.80) months after PCPIOL implantation. Four (44.4%) breaks were horseshoe tear, 1 (11.1%) was atrophic hole and 4 participants (44.4%) had a giant retinal tear. Nine cases had causative breaks located anterior to the equator while peripheral retina lattice degeneration was found in 6 eyes. RRD extended from 1 to 4 quadrants (3.0±1.12 quadrants) and 8 cases were macula-off retinal detachments. Four eyes’ proliferative vitreoretinopathy were more severe than level C. Initial reattachment rate was 77.80%. Final retinal reattachment was 100%. Final follow-up BCVA was significantly better than baseline (P<0.05). Furthermore, concurrent cataract occurred in 2 eyes in which silicone oil was used as tamponade. Ocular hypertension was detected in 4 eyes after surgery. Conclusion: The existed lattice degeneration and postoperative vitreous traction may be risk factors for RRD after PCPIOL implantation.

目的：观察学龄儿童的近视进展情况，分析近视进展的危险因素。方法：于2014年纳入温州2所小学二、三年级近视儿童，每年随访1次，直至小学毕业。检查内容包括非睫状肌麻痹主觉验光、双眼视功能检查(隐斜、调节性集合/调节、正负相对调节、正负融像性聚散)和问卷调查。采用无序多分类logistic回归分析近视进展速度的危险因素。结果：共纳入152名近视儿童[年龄7~9岁，95名(62.5%)男性]，初始屈光度为-1.30±0.95屈光度(diopter，D)，年近视进展量为-0.68±0.35 D。回归分析表明：与慢速组相比(年近视进展量>-0.50 D)，中速组(-1.00 D<年近视进展量≤-0.50 D)与快速组(年近视进展量≤-1.00 D)中初始屈光度≤-1.00 D的儿童占比更大(中速组：OR=3.51，P=0.003；快速组：OR=3.29，P=0.044)，快速组中女性占比更大(OR=4.52，P=0.012)，基线双眼视功能参数在不同组间差异均无统计学意义(均P>0.05)。结论：学龄儿童近视进展速度与性别、初始屈光度相关，与基线双眼视功能无关。女孩、初始近视程度大(7~9岁时，屈光度≤-1.00 D)的儿童近视进展快。

Objective: To investigate myopia progression and analyze the risk factors associated with myopia progression in a cohort of primary schoolchildren. Methods: The study was conducted in two primary schools in Wenzhou. Schoolchildren from grades 2 and 3 were examined in 2014 and were followed up annually until primary school graduation at grade 6. Children who were myopic at baseline were included in this study. The examination included non-cycloplegic subjective refraction, questionnaire survey, and binocular visual function parameters such as phoria, accommodative convergence/accommodation, positive relative accommodation, negative relative accommodation, and fusional convergence range. Multinomial logistic regression analysis was conducted to investigate the risk factors associated with various myopia progression speeds. Results: A total of 152 myopic schoolchildren [baseline age range 7–9 years; 95 male (62.5%)] were included in this study. The average refractive error (spherical equivalent refraction, SER) at baseline was -1.30±0.95 D, and the average annual myopia progression was -0.68±0.35 D. Multinomial logistic regression analysis showed that compared to the slow myopia progression group (annual myopia progression >-0.50 D), the moderate myopia progression group (-1.00 D < annual myopia progression ≤-0.50 D) and the fast myopia progression group (annual myopia progression ≤-1.00 D) were associated with having SER values ≤-1.00 D at baseline (moderate: OR=3.51, P=0.003; fast: OR=3.29, P=0.044); the fast myopia progression group was also associated with female sex (OR=4.52, P=0.012); baseline binocular visual function parameters were not related to various myopia progression speeds (P>0.05 for all). Conclusion: Sex and baseline refractive error were associated with various myopia progression among primary schoolchildren. No correlation between baseline binocular visual functions and myopia progression was found in this study. Myopia progressed faster in girls and children who had greater myopia (SER values ≤?1.00 D at age 7–9 years) at baseline.
