AIM: To investigate the prevalence and risk factors of dry eye(DE)among middle school students in Nantong.METHODS: A cross-sectional study was conducted among 1 939 middle school students in January 2021. The minimum sample size was calculated by cluster random sampling. A dry eye questionnaire was used to assess the prevalence and risk factors of DE in middle school students. DE was defined as often or all the time presence of one or more DE symptoms(i.e. “eye dryness” “grittiness” “burning sensation” “redness” “crusting of lashes” “eyelids getting stuck”). The risk factors associated with DE were evaluated by Logistics regression analysis.RESULTS: The prevalence of DE was 19.55%. The most reported dry eye symptom was “eyelids getting stuck”, accounting for 60.95%. Female(OR: 1.287, 95%CI: 1.018-1.626, P=0.035), the daily time of electrical appliances use at near distance >2h(OR: 1.927, 95%CI: 1.260-2.947, P=0.002), the daily time of reading and writing after class >3h(OR: 1.588, 95%CI: 1.214-2.079, P=0.001), frequent use of eye drops(OR: 1.908, 95%CI: 1.359-2.680, P6-8h, OR: 0.627, 95%CI: 0.477-0.823, P=0.001; >8h, OR: 0.511, 95%CI: 0.283-0.922, P=0.026)was an independent protective factor for the disease.CONCLUSION: The prevalence of DE among middle school students is high and should not be ignored. Preventive measures against risk factors may help to reduce the prevalence of DE and have a positive impact on the health of students.

AIM:To compare the efficacy of one initial intravitreal Conbercept injection(IVR)followed by pro re nata(PRN)dosing with that of three initial monthly IVR followed by PRN dosing in patients with macular edema(ME)after branch retinal vein occlusion(BRVO). METHODS: The clinical data of 35 cases were retrospectively analyzed; 20 received one initial IVR injection(1+PRN group)and 15 cases received 3-monthly IVRs(3+PRN). Both groups were followed monthly for 12mo. The best-corrected visual acuity(BCVA)and the macular central retinal thickness(CMT)on optical coherence tomography were evaluated before and after treatment, and the BCVA results were converted to the LogMAR visual acuity. RESULTS: The mean LogMAR BCVA and CMT, respectively, improved from 0.58±0.21 to 0.34±0.18 and from 561±65μm to 252±69μm in the “1+PRN” group(PP>0.05). During the study period, the mean total number of injections was significantly smaller in the “1+PRN” group than in the “3+PRN” group(2.3±1.2 and 4.1±1.1, respectively, PCONCLUSION: The two methods are both safe and effective for the treatment of BRVO combined with ME.

AIM: To explore clinical effect and influence factors of upper eyelid blepharoplasty combined with levator aponeurosis plication in general anesthesia for mild congenital ptosis in children.METHODS: According to relevant data before operation 40 eyes of 37 cases of children with mild congenital ptosis were treated with upper eyelid blepharoplasty combined with levator aponeurosis plication in general anesthesia. The clinical data were recorded and analyzed, the effect was evaluated.RESULTS: In the 40 eyes of 37 cases, the satisfactory rate was 78%(31 eyes), 5 eyes(12%)were under-corrected, 1 eye(2%)was over corrected, 3 eyes(8%)were return to back.CONCLUSION: The effect is affirmative that upper eyelid blepharoplasty combined with levator aponeurosis plication in general anesthesia treated the mild congenital ptosis in children, it is one of main methods for treating mild congenial ptosis in children.
