The fogging areas of wide-field lenses were microscopically measured. We created three groups: lenses soaked in normal saline at 25°C for 1 minute (control), lenses soaked in normal saline at 50°C for 1 minute (warm saline), and lenses that were wiped with a sponge soaked in anti-fog solution (ULTRASTOP pro med. Solution, Sigmapharm, Vienna, Austria) after prior soaking in normal saline at 25°C for 1 minute (anti-fog). Images of fogged areas were acquired at 10 seconds and 1, 3, and 5 minutes. Extent of fogged areas and central lens invasion were determined. All experiments were repeated 10 times.Results: In the control group, the entire areas were always completely fogged. The average fog coverage values were 4.34 ± 1.28, 6.30 ± 1.38, 56.00 ± 25.01, and 93.81 ± 5.88% at 10 seconds and 1, 3, and 5 minutes in the warm saline group and 4.74 ± 0.57, 7.35 ± 0.96, 10.13 ± 1.09, and 11.74 ± 1.74% in the anti-fog group, respectively. There were significant differences at 3 and 5 minutes (p = 0.029, p = 0.012). Fogging of the central lens was detected in 8 tests after 3 minutes and all 10 tests after 5 minutes in the warm saline group, but no fogging was detected in the anti-fog group.Conclusions: Application of an anti-fog solution to a wide-field viewing lens prevents lens fogging during vitrectomy.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136185312","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}

Data were extracted from the Korean National Health Insurance System database. The incidence and prevalence per 10,000 person-years and corresponding 95% confidence intervals were calculated. Furthermore, we recorded the usage of ranibizumab and aflibercept among newly diagnosed patients with neovascular AMD between 2010 and 2014.Results: In total, 90,012 patients were diagnosed with neovascular AMD between 2010 and 2019. The incidence of neovascular AMD increased with age, except for individuals aged ≥ 90 years. The prevalence of neovascular AMD increased significantly from 30.29 per 10,000 person-years in 2010 to 50.8 per 10,000 person-years in 2019. The rate of intravitreal ranibizumab injections decreased following the introduction of aflibercept in 2014. Patients who switched from ranibizumab to aflibercept exhibited a higher drug switch rate than those who switched from aflibercept to ranibizumab (28.83% vs. 8.40%). Among newly diagnosed patients, approximately 65% received treatment covered by the health insurance system. On average, six injections were administered per year between 2010 and 2019; the number of injections increased in accordance with the maximum limit supported by the government.Conclusions: The incidence and prevalence of neovascular AMD demonstrated an increasing trend. The treatment patterns are influenced by changes in government funding support policies. These findings provide valuable information for planning neovascular AMD treatment.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136185021","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}

In total, 71 patients were administered acetaminophen and diazepam orally, while the remaining 50 were not. Postoperative pain (measured using the visual analogue scale [VAS] score [0 = no pain, 10 = severe pain] immediately after operation), operative duration, and improvement in epiphora symptoms were compared between the two groups.Results: The premedication group had significantly lower VAS scores than the non-premedication group (5.23 ± 2.75 vs. 6.34 ± 2.33, p = 0.02). It also had a notably shorter (p < 0.01) operation duration and higher subjective improvement rate of epiphora symptoms. However, premedication did not influence the tube retention period post-surgery (p = 0.86).Conclusions: The administration of analgesics and sedatives prior to silicone tube intubation effectively mitigates operative pain and reduces operation duration.

She had high myopia of -12.5 diopter (spherical equivalent) and a corrected visual acuity of 2/100. The fundus photograph and optical coherence tomography showed a full-thickness macular hole measuring 688 µm in width and 976 µm in length. The ILM around the hole was detached from the retinal surface, which was greater in size than the macular hole. The initial surgical intervention involved vitrectomy, inverted ILM flap placement, and gas tamponade. The decrease in gas volume was associated with a loss of the ILM flap. For hole closure, the remaining ILM flap in the peripheral macula was harvested and inserted in the hole during the second surgery. The silicone oil was used for tamponade. One month after ILM insertion, complete closure of the hole was observed. The visual acuity improved to 20/40 after silicone oil removal.Conclusions: A large full-thickness macular hole developed after ICL implantation in a patient with high myopia. Macular hole surgery using ILM insertion and prolonged tamponade closed the hole and effectively improved the visual acuity.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136185019","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 measured the central macular thickness (CMT), subfoveal choroidal thickness, and CVI of the BRVO eyes and the fellow eyes using optical coherence tomography and then analyzed the correlation between these measurements and visual and anatomical outcomes.Results: After six months of treatment, the best corrected visual acuity improved, and CMT decreased. Multiple linear regression analysis revealed that factors associated with best corrected visual acuity improvement at six months were fellow eye CVI (standardized β = 0.346, p = 0.008), ellipsoid zone integrity (standardized β = 0.398, p = 0.001), and initial best corrected visual acuity (standardized β = 0.590, p < 0.001). Initial CMT (standardized β = 0.563, p < 0.001) was the only factor associated with the decrease in CMT at six months.Conclusions: In cases of severe macular edema, accurate evaluation of choroidal vessels can be challenging due to shadowing. We discovered that a larger CVI in the fellow eye was associated with greater visual improvement in patients with BRVO and macular edema. CVI could be a prognostic factor for predicting treatment outcomes in BRVO patients, suggesting that the choroidal vascular status may play a role in the pathophysiology of BRVO.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136185316","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 divided patients into the “treatment success group” (patients whose infection resolved) and the “treatment failure group” (patients whose infection worsened and required evisceration). Clinical characteristics, such as infection-related ocular findings and microbiological features, were analyzed retrospectively in both groups. Chi-square tests and logistic regression analyses were performed to identify prognostic factors associated with treatment failure.Results: The mean age of patients was 72.8 ± 11.92 years, with 17 (42.5%) of them being male. Among the patients, 11 had bacterial infections, and 3 had fungal infections. In total, 6 (15%) and 34 (85%) patients were classified into the treatment success and failure groups, respectively. The chi-square test revealed a significant association between the treatment failure group and several clinical factors, such as low best corrected visual acuity (BCVA), the logarithm of the minimum angle resolution (logMAR) BCVA > 2, low intraocular pressure (IOP) < 5 mmHg, large size of the corneal lesion, and the presence of hypopyon (p < 0.05). Furthermore, the multivariate logistic regression analysis identified hypopyon as a significant risk factor for treatment failure (p = 0.036).Conclusions: A significantly high treatment failure rate of 85% was observed in patients with ocular infections accompanied by orbital and preseptal cellulitis. Several clinical factors, such as low BCVA with logMAR BCVA > 2, IOP < 5 mmHg, large size of the corneal lesion, and a prolonged duration of symptoms demonstrated significant association with treatment failure.
