The differences in pRNFLT, mGCIPLT and MT between the two groups were assessed using SS-OCT. Furthermore, the patients were divided into three glaucoma-severity groups, and the differences in pRNFLT, mGCIPLT and MT were compared between glaucoma patients with and without ERM in each group.Results: In all patients, including those with early, moderate, and advanced glaucoma, those with ERM had greater average, temporal quadrant, and 7, 8, 9, 10, and 11 o’clock pRNFLT values compared to those without ERM. Additionally, mGCIPLT and MT were thicker in glaucoma patients with ERM in all groups. The difference in pRNFLT at the 7 and 11 o’clock positions between glaucoma patients with and without ERM was significantly more pronounced in the moderate glaucoma group than in the early glaucoma group (p = 0.043 and p = 0.012, respectively).Conclusions: ERM has notable effects on the pRNFLT, mGCIPLT and MT. Furthermore, the magnitude of its effect on pRNFLT varies with glaucoma severity.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138998809","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 assessed visual acuity using the logarithm of the minimal angle of resolution (logMAR) scale and evaluated the visual performance of both groups, including uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA) and the defocus curve at 1 month postoperatively. In addition, we measured contrast sensitivity and administered a satisfaction questionnaire at 3 months postoperatively.Results: At 1 month postoperatively, group B demonstrated significantly better monocular UDVA, UNVA and binocular UNVA compared to group A (0.07 ± 0.07, 0.24 ± 0.16, and 0.18 ± 0.15 vs. 0.13 ± 0.09, 0.33 ± 0.14, and 0.29 ± 0.11; p < 0.05). In addition, group B exhibited higher visual acuities in the monocular and binocular defocus curves at +1.00 diopters (D), -3.00 D, -3.50 D, and +1.00 D (p < 0.05). Notably, the binocular defocus curves of both groups demonstrated excellent logMAR visual acuities (better than 0.2) in the range of 0.00 to -3.00 D. However, no significant differences were observed between the groups in contrast sensitivity or satisfaction questionnaire responses for visual acuity at 3 months postoperatively (p > 0.05).Conclusions: The hybrid multifocal-EDOF IOL demonstrates superior near visual acuity compared to the diffractive trifocal IOL.

Many respondents (91, 57.6%) reported knowing the criteria for low vision, but approximately half (74, 46.9%) reported that they had little or no knowledge of low vision in general. More than half of the respondents (87, 55.1%) had never written a prescription for a visual aid, and only 32 (20.2%) were able to prescribe such aids. The principal reasons for hesitation in the treatment of low-vision patients were lack of knowledge (117, 74.5%) and poor medical reimbursement (41, 26.1%). Many respondents (152, 96.2%) wanted to learn more about low vision, and approximately half (71, 45.5%; 74, 47.4%) felt that the current low-vision care environment in Korea requires improvement.Conclusions: Despite the increasing need for low-vision care in South Korea, the number of ophthalmologists who can provide such care (including prescriptions for visual aids) is insufficient. Lack of education and poor medical reimbursement are important problems. Low-vision clinics must promote outreach activities, and institutions should develop programs to educate ophthalmologists.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138999443","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}

Patients who experienced binocular diplopia for > 6 months were included in the diplopia group.Results: After surgery, 22 patients (5.3%) developed binocular diplopia. There were no significant correlations of diplopia onset with buckle position (i.e., the affected muscle), cryophotocoagulation, subretinal fluid drainage, and the use of gas or oil injections. Prism therapy restored binocular single vision in three patients. Ten patients chose to undergo strabismus surgery, and one patient underwent encircling band removal. All strabismus surgery patients displayed adhesion between the buckle and extraocular muscle. After surgery, 60% of these patients regained binocular single vision.Conclusions: Clear risk factors leading to ocular movement disorders and diplopia after scleral buckling remain undefined. If diplopia persists despite prism-based conservative treatment, strabismus surgery may offer relief.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138998246","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 patient had a history of ophthalmologic surgeries, including cataract surgery in both eyes and intraocular lens trans-scleral fixation in the right eye. A primary suture was performed in the right eye due to iris prolapse through the scleral incision site and anterior chamber hemorrhage. At 1 week post-surgery, the patient reported diminished visual acuity in the left eye. Further assessment using wide-field fundus photography, optical coherence tomography, and fluorescein angiography revealed multiple focal hyperfluorescence leakage and serous retinal detachment. Consequently, sympathetic ophthalmia was diagnosed. Intravenous administration of high-dose steroids led to significant symptom improvement.Conclusions: We present a patient with a history of multiple ophthalmic surgeries and contralateral eye trauma indicative of sympathetic ophthalmia.

We calculated the root mean square values (μm) of corneal total HOA and of the corneal 3rd- and 4th-order HOA at a pupil diameter of 4 mm.

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.
