His visual acuity was 1.0 before the injection and decreased to 0.1 at the presentation. On slit-lamp examination, a snow-flake appearance opacity was noted behind the posterior capsule. No newly appearing lesion was presented on fundus exam, so topical antibiotics and steroid eyedrops were continued. One week after the injection, the visual acuity improved to 1.0 and posterior capsular opacity remained but decreased. Five weeks after the injection, the posterior capsular opacity resolved. Fundus exam revealed improved but persistent subretinal fluid, so he overwent another intravitreal injection. The posterior capsular opacity did not recur for seven months.Conclusions: Iatrogenic lens damage or the turbidity formed by medication can cause a posterior capsular opacity after intravitreal injection. If structural damage is uncertain, close monitoring is needed and ultimately, cataract surgery may be required for chronic crystalline lens opacity.","PeriodicalId":504314,"journal":{"name":"Journal of the Korean Ophthalmological Society","volume":"4 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139273515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We enrolled patients exhibiting only best-corrected visual acuities ≤ 20/100 of the operated eyes. Surgical success was defined as a final distance deviation < 10 prism diopters (PD) with the eye in the primary position. Twenty-eight patients operated upon to treat sensory exotropia and 28 who underwent operations to treat concomitant exotropia who did not differ in terms of the gaze deviation angle were matched in terms of age, sex, and the preoperative distance and near distributions; their surgical outcomes were compared. Factors affecting such outcomes were identified using a multivariate Cox’s proportional hazards model.Results: The mean follow-up times were 91.7 ± 45.8 months in the sensory and 42.6 ± 27.7 months in the concomitant exotropia groups. The cumulative probabilities of surgical success 2 years after surgery were 74.5% in the sensory and 74.4% in the intermittent exotropia groups, thus not significantly different (p = 0.988). The Cox’s proportional hazard model showed that a greater difference between the preoperative distant and near deviations was associated with recurrence (p = 0.091).Conclusions: The long-term surgical outcomes of patients with sensory and concomitant exotropia were comparable. A high-level near-distance disparity increased the risk of recurrence.","PeriodicalId":504314,"journal":{"name":"Journal of the Korean Ophthalmological Society","volume":"47 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139273661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A control group of 20 patients (40 eyes) was also recruited. The thickness of the NFL-GCIPL macular complex was measured using OCT, and the densities of the superficial and deep macular retinal vessels were evaluated via OCTA in all subjects.Results: The NFL-GCIPL thicknesses of the superior, inferior, temporal, and nasal sectors were 94.70 ± 9.35, 93.32 ± 9.16, 90.18 ± 6.32, and 93.11 ± 8.75 μm in the control group and 92.05 ± 4.96, 91.32 ± 7.48, 84.74 ± 6.82, and 91.32 ± 7.47 μm in the Parkinson’s disease group, respectively; all thicknesses were significantly greater in the control group. The superficial and deep retinal vessel densities did not differ between the two groups.Conclusions: Neurodegenerative macular changes are more obvious than microvascular changes in patients with early Parkinson’s disease. Such neurodegenerative changes should be further evaluated in future cohort studies.","PeriodicalId":504314,"journal":{"name":"Journal of the Korean Ophthalmological Society","volume":"E-29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139274323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The IOL master 700 platform was used to derive axial length, corneal curvature (the K value), central corneal thickness, anterior chamber depth, lens thickness, and the white-to-white size at 1-year intervals. The Mann-Whitney and Wilcoxon signed-ranked tests were used to compare the values. A p-value < 0.05 was taken to indicate a significant difference.Results: The mean ages of hyperopic and myopic children were 6.27 ± 0.87 and 6.93 ± 0.87 years at initial presentation. Significant 1-year changes in axial length, anterior depth, and lens thickness were apparent. The mean corneal curvature, and central corneal and lens thicknesses were significantly higher in hyperopic than myopic children but the axial length and anterior chamber depth were significantly greater in myopic children. However, after 1 year, the lens thicknesses did not significantly differ between the two groups.Conclusions: Over 1 year of early life, changes in the mean corneal curvature and lens thickness were significant in hyperopic children and changes in the axial length and anterior depth were significant in myopic children. Thus, the eye growth pattern may differ between hyperopic and myopic children.","PeriodicalId":504314,"journal":{"name":"Journal of the Korean Ophthalmological Society","volume":"46 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139271196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
