Purpose: To identify initial factors contributing to the resistance against intravitreal aflibercept treatment in polypoidal choroidal vasculopathy (PCV) patients.Methods: This study included PCV patients initially treated with aflibercept. Resistance was defined when treatment did not reduce subretinal fluid (SRF) or intraretinal fluid (IRF) by 100 μm or more after three consecutive 4-week intervals, and the treatment interval could not be extended beyond 8 weeks. To identify initial factors associated with resistance to aflibercept treatment, we examined visual acuity and central choroidal thickness before initial treatment and after three treatments. Choroidal thickness was divided into the thickness of the large choroidal vessel layer and the layer that includes choriocapillaris and medium choroidal vessel thickness (termed medium choroidal vessel/choriocapillaris layer thickness, MCCT). Additionally, the volume of SRF, IRF, subretinal hyperreflective material, and pigment epithelial detachment in optical coherence tomography (OCT) images was investigated. The statistical significance of each factor was assessed through logistic regression analysis.Results: The study included 39 eyes showing no resistance to aflibercept and 37 eyes that exhibited resistance. Multiple logistic regression analysis, adjusted for age and sex, indicated that a lower initial ratio of MCCT to choroidal thickness at the fovea was associated with resistance to aflibercept.Conclusions: In patients with PCV treated with aflibercept, early OCT anatomical structures, such as the initial MCCT-choroidal thickness ratio at the fovea, may predict response to treatment injections.
目的：确定导致多形性脉络膜血管病（PCV）患者对玻璃体内阿弗利百普治疗产生耐药性的初始因素：本研究纳入了最初接受阿弗利百普治疗的PCV患者。当治疗连续三次间隔4周后，视网膜下积液（SRF）或视网膜内积液（IRF）仍未减少100 μm或更多，且治疗间隔不能超过8周时，即定义为耐药。为了确定与阿弗利百普治疗耐药性相关的初始因素，我们检查了初始治疗前和三次治疗后的视力和中心脉络膜厚度。脉络膜厚度分为大脉络膜血管层厚度和包括绒毛膜和中脉络膜血管层厚度（称为中脉络膜血管/绒毛膜层厚度，MCCT）。此外，还对光学相干断层扫描（OCT）图像中的 SRF、IRF、视网膜下高反射物质和色素上皮脱落的体积进行了调查。通过逻辑回归分析评估了各因素的统计学意义：研究包括39只对阿弗利百普无耐药性的眼睛和37只表现出耐药性的眼睛。根据年龄和性别进行调整后的多元逻辑回归分析表明，MCCT与眼窝处脉络膜厚度的初始比值较低与阿弗利百普耐受性有关：结论：在接受阿弗利百普治疗的 PCV 患者中，早期 OCT 解剖结构（如眼窝处的初始 MCCT 与脉络膜厚度比）可预测对治疗注射的反应。

Purpose: To assess the impact of cataract on optic nerve head (ONH) parameters (disc area, rim area, average cup/disc ratio, vertical cup/disc ratio, cup volume), peripapillary retinal nerve fiber layer (pRNFL) thickness, and macular ganglion cell-inner plexiform layer (mGC-IPL) thickness in patients with glaucoma and in a control group.Methods: A retrospective analysis was conducted on medical records from January to December 2021 for individuals undergoing cataract surgery. This group included normal, glaucoma suspects, and glaucoma patients, totaling 44 individuals and 63 eyes. Measurements of ONH parameters, pRNFL thickness, and mGC-IPL thickness were taken using spectral-domain optical coherence tomography before and after surgery. We analyzed postoperative changes in these parameters and related factors to preoperative segmentation errors.Results: In glaucoma patients, a significant increase in the average thickness of the pRNFL (p = 0.002) was observed after surgery, while no significant changes were seen in ONH parameters and the average thickness of the mGC-IPL (all p > 0.05). Conversely, the control group showed an increase in some areas of mGC-IPL thickness after surgery (p < 0.05). Multivariate regression analysis indicated that in glaucoma patients, thinner preoperative pRNFL and mGC-IPL thickness were predictors of increased average thickness after surgery (p < 0.001 and p = 0.008, respectively).Conclusions: Cataract significantly impacts the pRNFL and mGC-IPL thickness in glaucoma patients, with less effect on ONH parameters. These findings suggest that ONH parameters can be more reliable for monitoring patients undergoing cataract surgery and assessing glaucoma progression simultaneously.

Purpose: To analyze changes in astigmatism and visual acuity in pediatric patients with limbal dermoid before and after surgery.Methods: Twenty-five pediatric patients (7 male, 18 female) diagnosed with limbal dermoid from March 2018 to February 2022 were included. We analyzed best corrected visual acuity and astigmatism using cycloplegic refraction, automated keratometry, and topography before and after surgery.Results: In cycloplegic refraction and automated keratometry, postoperative astigmatism did not decrease significantly (p = 0.53 and p = 0.38, respectively). Topography showed a significant decrease in corneal astigmatism from 3.6 ± 2.8 diopters (D) to 2.7 ± 1.8 D (p < 0.05) and in irregular astigmatism from 3.7 ± 2.2 D to 2.5 ± 1.5 D (p < 0.001). Significant decreases were observed in the corneal irregularity index from 0.14 ± 0.10 mm to 0.08 ± 0.47 mm (p < 0.001) and in the index of surface variance from 60.56 ± 41.02 to 35.00 ± 16.00 (p < 0.001). There was a statistically significant improvement in best corrected visual acuity from logarithm of minimal angle of resolution (logMAR) 0.18 to logMAR 0.07 (p < 0.05).Conclusions: Surgery for limbal dermoid significantly reduced irregular astigmatism and improved best-corrected visual acuity. It is suggested that achieving visual development through active amblyopia treatment after surgery is important.

Purpose: We present a case of internal astigmatism correction using a toric scleral contact lens in a patient with high myopia after implantable collamer lens (ICL) surgery.Case summary: A 45-year-old man presented with a significant decrease in visual acuity despite previous ICL surgery. Initial attempts to fit a corneal rigid gas permeable contact lens to the left eye were unsuccessful due to fitting challenges. Subsequently, the use of a spherical scleral contact lens effectively corrected corneal astigmatism but failed to address internal astigmatism, thereby limiting improvement in visual acuity. Postoperative corneal ectasia and ICL rotation were suspected to be the underlying causes of this astigmatism. The introduction of a front toric scleral lens resulted in a significant improvement in visual acuity and sustained comfort throughout the 3-month follow-up period.Conclusions: The use of toric scleral lenses can significantly improve visual acuity and provide exceptional comfort in cases where corneal morphology and lens position change after ICL surgery. This modality presents a promising alternative for future consideration.

Purpose: To evaluate the efficacy of topical bromfenac in treating central serous chorioretinopathy (CSC) over a 1-year period.Methods: A retrospective analysis was conducted on 57 patients (57 eyes) with CSC followed for > 1 year. Patients were divided into two groups: those treated with bromfenac eye drops twice daily (29 eyes) and a control group (28 eyes). Best-corrected visual acuity (BCVA), central macular thickness (CMT), and subretinal fluid (SRF) height were measured and compared between the two groups as was the proportion of chronic cases.Results: Significant improvements in CMT and SRF height were noted in both groups over the follow-up period. The bromfenac group demonstrated significantly lower CMT at 6, 9, and 12 months (p = 0.045, 0.042, and 0.023, respectively) and lower SRF height (p = 0.037, 0.048, and 0.046, respectively) compared to the control group. The proportion of chronic cases was significantly lower in the bromfenac group (17.2%) compared to the control group (42.9%, p = 0.035).Conclusions: Topical bromfenac reduced the rate of progression to chronic CSC and showed significant anatomical improvements after 6 months, suggesting its potential as an effective treatment option.

Purpose: We present two cases of multiple evanescent white dot syndrome (MEWDS) following COVID-19 vaccination.Case summary: We present two cases of visual field defects following BNT162b2 (Pfizer-BioNTech, Kronach, Germany) COVID-19 vaccination. A 14-year-old male experienced reduced visual acuity in the temporal field of his left eye after his second dose. Similarly, a 38-year-old woman experienced decreased visual acuity in her right eye after her first dose. Notably, neither patient had pre-existing medical conditions or exhibited COVID-19 symptoms following vaccination. Funduscopic examination revealed multifocal peripapillary hyperreflective lesions in both cases. Visual field defects and hyperreflective lesions spontaneously resolved within 6 weeks, with normal visual acuity and fundus findings at the 7-month follow-up.Conclusions: The recent COVID-19 pandemic has led to a significant increase in vaccination rates. Notably, MEWDS demonstrated a significant association with previous vaccines, including influenza and hepatitis, and the cases describe herein also suggest a potential association between BNT162b2 vaccination and MEWDS.

Purpose: We present an atypical case of cytomegalovirus corneal endotheliitis after intravitreal triamcinolone injection.Case summary: A 61-year-old man presented with decreased visual acuity after intravitreal triamcinolone (Maqaid®, Wakamoto Pharmaceutical Co., Ltd., Tokyo, Japan) injection for cystoid macular edema following cataract surgery. Ocular examination revealed elevated intraocular pressure, diffuse keratic precipitates with corneal edema, and anterior chamber inflammation. These findings were suggestive of viral corneal endotheliitis. Polymerase chain reaction analysis of the anterior chamber aqueous humor detected cytomegalovirus DNA. Consequently, the patient was diagnosed with cytomegalovirus corneal endotheliitis. He was treated with oral valganciclovir (Valcyte®, Roche, Basel, Switzerland) at a dose of 1,800 mg/day for 3 weeks as an induction phase, followed by 900 mg/day for 3 weeks as a remission phase. This treatment regimen led to significant improvement in corneal edema and anterior chamber inflammation with complete restoration of visual acuity.Conclusions: It is important to note that cytomegalovirus endotheliitis can occur after intravitreal triamcinolone injection and can present in an atypical rather than a typical form.

Purpose: To examine the clinical characteristics, demographic features, and visual prognosis of idiopathic intracranial hypertension (IIH) in Korean patients.Methods: We conducted a retrospective chart review of patients diagnosed with IIH who visited the Neuro-ophthalmology Clinic at Samsung Medical Center from September 2011 to January 2023. This analysis focused on demographic characteristics at onset, clinical manifestations, and visual outcomes at the last follow-up.Results: Out of 34 patients, 20 met the modified Dandy criteria and 14 were presumed to have IIH. The mean age at onset was 32.97 ± 9.6 years with females comprising 85.3% (n = 29) of the sample. The average body mass index (BMI) was 29.15 ± 6.43, with 47.0% of patients (n = 16) classified as obese. The most frequent symptom was headache, reported by 85.3% (n = 29) of patients, followed by pulsatile tinnitus (64.7%, n = 22) and transient visual obscuration (TVO; 32.4%, n = 11). Treatment included observation for 3 patients (8.8%), acetazolamide therapy for 26 patients (76.5%), and ventriculo-peritoneal shunt (V-P shunt) for 2 patients (5.9%). Out of 23 patients with follow-up > 6 months, 87.0%, 8.7%, and 4.3% showed good, fair, and poor visual outcomes, respectively; optic nerve atrophy was observed in 19.6% (9 eyes). The initial peripapillary retinal nerve fiber layer (pRNFL) thickness measured by OCT was 143.56 ± 62.41 μm in the right eye and 139.3 ± 76.38 μm in the left which decreased to 97.39 ± 25.72 and 94.91 ± 19.32 μm, respectively by the last examination.Conclusions: While the proportion of obese patients in this Korean cohort and the average BMI were lower than in western countries, both have increased relative to previous reports from Korea. Most patients experienced a benign course.

Treatment included observation for 3 patients (8.8%), acetazolamide therapy for 26 patients (76.5%), and ventriculo-peritoneal shunt (V-P shunt) for 2 patients (5.9%). Out of 23 patients with follow-up > 6 months, 87.0%, 8.7%, and 4.3% showed good, fair, and poor visual outcomes, respectively; optic nerve atrophy was observed in 19.6% (9 eyes). The initial peripapillary retinal nerve fiber layer (pRNFL) thickness measured by OCT was 143.56 ± 62.41 μm in the right eye and 139.3 ± 76.38 μm in the left which decreased to 97.39 ± 25.72 and 94.91 ± 19.32 μm, respectively by the last examination.Conclusions: While the proportion of obese patients in this Korean cohort and the average BMI were lower than in western countries, both have increased relative to previous reports from Korea. Most patients experienced a benign course.","PeriodicalId":504314,"journal":{"name":"Journal of the Korean Ophthalmological Society","volume":"18 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141647725","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}

Purpose: We present a case of bilateral compressive optic neuropathy secondary to orbital myositis after COVID-19 messenger ribonucleic acid (mRNA) vaccination.Case summary: A 51-year-old man developed acute bilateral visual loss and painful ophthalmoplegia shortly after receiving the second dose of the BNT162b2 COVID-19 mRNA vaccine (Comirnaty, Pfizer®, New York, NY, USA). His best-corrected visual acuity was counting fingers at 30 cm and 50 cm in the right and left eyes, respectively. Bilateral eyelid swelling, erythema, conjunctival injection, and color vision deficit were observed. Orbital magnetic resonance imaging revealed diffuse enhancement and hypertrophy of the bilateral extraocular muscles. The patient had no significant ophthalmic history and systemic work-up revealed no evidence of underlying inflammatory disease. Based on the clinical presentation and imaging findings, he was tentatively diagnosed with bilateral compressive optic neuropathy secondary to orbital myositis after COVID-19 mRNA vaccination. He was treated with intravenous corticosteroids for 3 days followed by low-dose oral corticosteroids. One month later, his visual acuity and color vision improved; moreover, the inflammatory signs in the eyelids, conjunctiva, and extraocular muscles resolved. However, after developing COVID-19, he experienced a recurrence of symptoms and was retreated with corticosteroids. Radiotherapy was administered to address persistent color vision deficit in the right eye and recurrent eyelid edema, erythema, and conjunctival injection. This treatment effectively resolved all inflammatory signs and color vision deficits, without signs of recurrence.Conclusions: Acute fulminant orbital myositis with associated compressive optic neuropathy can manifest after COVID-19 mRNA vaccination and onset of COVID-19. Anti-inflammatory treatment measures can effectively control these manifestations.

Purpose: Stickler syndrome, a hereditary connective tissue disorder characterized by mutations in collagen genes, presents with progressive ophthalmopathy and diverse systemic manifestations. Here, we present three familial cases of Stickler syndrome, emphasizing the importance of early detection through clinical investigations and genetic testing.Case summary: Two generations of a family, a mother and her two daughters, were evaluated for Stickler syndrome. All three exhibited bilateral retinal lattice degeneration, perivascular retinal degeneration, and vitreous liquefaction. The daughters shared characteristic facial features, including a flattened face, broad nasal bridge, and micrognathia. Clinical symptoms and examination findings led to diagnoses of Stickler syndrome. Subsequent genetic testing in five family members confirmed a COL2A1 mutation in the three affected individuals.Conclusions: Stickler syndrome carries a high risk of vision loss from ocular complications, necessitating early detection and intervention. In addition, the presence of systemic manifestations, such as musculoskeletal joint disorders, mitral valve prolapse, hearing loss, and cleft palate, emphasizes the importance of prompt detection through appropriate clinical investigations and genetic testing.
