We analyzed the initial and recurrent clinical features of HSK, the recurrence rate, and the relationship between recurrence and the duration of oral antivirals.Results: The mean age of the patients was 64.5 ± 14.0 years, and the mean follow-up duration was 72.4 ± 40.3 months. Of the 30 eyes, 21 (70%) experienced HSK recurrence. The initial clinical features of recurrent cases included herpetic epithelial keratitis (14.3%), stromal keratitis (47.6%), and endotheliitis (38.1%). Notably, no significant associations were observed between the initial clinical features of HSK or the duration of oral antivirals and HSK recurrence. However, male patients exhibited a significantly higher recurrence rate. Epithelial keratitis (47.6%) was the most common HSK type observed during recurrence.Conclusions: A recurrence rate of 70% was observed in patients who received prophylactic oral antiviral treatment for > 6 months. Herpetic epithelial keratitis was the most common clinical phenotype after recurrence. Notably, long-term clinical monitoring could assist in predicting and preventing recurrence.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139623059","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}

These images were captured using a digital fundus camera (KOWA Nonmyd 8S Fundus Camera, KOWA Company, Nagoya, Japan) without pupil dilation. We used two mathematical algorithms: DCP only and DCP and BCP combined. The original, DCP-processed, and DCP & BCP-processed images were compared. Fisher's exact test was used to identify significant quality improvements.Results: The DCP and the newly proposed DCP plus BCP algorithm effectively eliminated haze and enhanced the contrast of cataract images. Notably, DCP demonstrated limited improvements in fundus photographs from patients with small pupils, whereas the proposed DCP plus BCP method effectively revealed previously obscured retinal details and vessels. However, these methods exhibited limited performance in severe cataracts compared to the clear images obtained after surgery. The quality enhancement with the proposed method was significant in photographs of patients with cataracts (p = 0.032) and small pupils (p < 0.01).Conclusions: Our algorithm produced clearer images of blood vessels and optic disc structures, while significantly reducing artifacts in fundus images from patients with small pupils or cataracts. The proposed algorithm can provide visually enhanced images, potentially aiding physicians in the diagnosis of retinal diseases in patients with cataracts.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139622979","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 retrospective analysis categorized patients into non-recurrence and recurrence groups. Data on visual acuity, spherical equivalent, intraocular pressure, number of injections, and follow-up duration were collected from medical records. OCT images were obtained before and 6 months after intravitreal injection to measure and analyze central retinal thickness, subfoveal choroidal thickness, and disorganization of retinal inner layers.Results: No statistically significant difference was observed in the central retinal thickness change before and after treatment between the groups. Although no significant differences were observed in visual acuity between the two groups before treatment, significant improvement in visual acuity was observed in the non-recurrence group after 6 months of treatment. The non-recurrence group was younger compared to the recurrence group; moreover, the intraocular pressure in non-recurrence patients decreased significantly during the 6-month treatment period. In addition, a decrease in subfoveal choroidal thickness before and after treatment, the difference in subfoveal choroidal thickness between the affected eye and the fellow eye before treatment, and the reduction in disorganization of retinal inner layers before and after treatment were associated with a favorable prognosis without recurrence.Conclusions: Changes in subfoveal choroidal thickness before and after treatment, variations in subfoveal choroidal thickness between the affected and fellow eyes before treatment, and the degree of disorganization of retinal inner layers exhibited significant associations with the recurrence of macular edema. This is significant because it allows for predictions based on baseline OCT images.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139620450","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 reported experiencing bloody tears in his right eye approximately once per month during stressful events for the preceding 6 years. These episodes were associated with ocular pain, right-eye hyperemia, headaches, and nausea. However, these symptoms of bloody tears spontaneously resolved without intervention. Corrected visual acuity in the right eye was 1.0, and the intraocular pressure was 16 mmHg. There were no abnormalities in the ocular appendages, anterior chamber, or eyelids. Nasolacrimal duct probing and irrigation, as well as fundus examination, revealed normal findings. Brain and orbital magnetic resonance imaging did not show abnormalities in the brain or the orbital region, although slight mucosal thickening was present around the right lacrimal gland. Other examinations, including an electrocardiogram, chest X-ray, blood test, and nasal endoscopy, all revealed normal findings.Conclusions: Recurrent bloody tears (hemolacria) occurred in the right eye of a 19-year-old man with no history of trauma, intraocular surgery, or underlying medical conditions. Comprehensive ophthalmic examination and brain and orbital magnetic resonance imaging failed to identify any specific abnormalities leading to a diagnosis of idiopathic hemolacria.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139621095","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 best corrected visual acuity was 1.2 in both eyes with a left relative afferent pupillary defect. Cells in the anterior chamber, optic disc edema, and subretinal fluid were present, and the distal optic nerve was enhanced on orbital magnetic resonance imaging. Although it improved with steroid treatment, it recurred 3 times in 9 months. At the second recurrence, her visual acuity was reduced to light perception, but she responded well to steroids. During the third recurrence, she visited our hospital for the first time and improved with steroid treatment. However, 18 months after treatment, optic neuritis, uveitis, and macular edema occurred, so oral steroids and eye drops were maintained. Serum anti-MOG antibody came out positive, and at the last visit, visual acuity of 1.2 in the left eye and visual function were maintained well.Conclusions: MOG antibody disease (MOGAD) frequently recurs and invades various structures of the eye and various clinical manifestations have been reported.

The patient presented with eyelid swelling and retinal hemorrhage as well as optic disc swelling of the left eye. Optical coherence tomography (OCT) showed parafoveal intraretinal fluid. The patient received the intravenous high-dose steroids and the immune globulin therapy. He was then put on maintenance oral steroids and immunosuppressive agents. After the treatment, the best corrected visual acuity of left eye was improved to 0.2. Retinal hemorrhage and retinal edema of the left eye decreased, and optic nerve pale in both eyes was observed. OCT showed overall atrophy of the retinal nerve fiber layer in both eyes.Conclusions: Some patient with MOG-IgG positive optic neuritis will have eyelid swelling or retinal edema that is necessary to be differentiated from eyelid inflammatory disorder or macular disease such as diabetic retinopathy. Thus, clinician should consider MOG-IgG positive optic neuritis in patients with retinal edema when accompanied by eye pain with severe vision loss or repeated disc swelling. When diagnosed with MOG-IgG positive optic neuritis, a combined treatment of relatively long-term steroid treatment and immunosuppressants may be required.","PeriodicalId":17341,"journal":{"name":"Journal of The Korean Ophthalmological Society","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139529440","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}

Next, we conducted a multivariate analysis, adjusting for age, sex, education level, and survey year.Results: Significant differences were observed in age, sex, and educational levels between the two groups. After propensity score matching, the OAG group demonstrated a significantly elevated intraocular pressure (IOP), myopia prevalence, systolic blood pressure (SBP), and diastolic blood pressure (DBP). In addition, that group exhibited a significantly increased prevalence of hypertension and melancholic mood disorders and aspartate transaminase/alanine transaminase (AST/ALT) ratio. Multiple logistic regression revealed elevated IOP, SBP, DBP, AST/ALT ratio, and prevalence of hypertension, melancholic mood, and myopia as OAG risk factors.Conclusions: Our study revealed several risk factors for OAG, including elevated IOP, SBP, DBP, AST/ALT ratio, and prevalence of hypertension, melancholic mood, and myopia. However, the mechanism underlying OAG remains uncertain. Notably, a positive correlation was observed between the AST/ALT ratio and OAG risk.

A total of 228 eyes of 228 patients who underwent uncomplicated cataract surgery between October 2015 and March 2021 were included. The accuracy of nine IOL calculation formulas (Kane, Emmetropia verifying optical version, Hill-radial basis function, Olsen, Barrett Universal II [Barrett II], Haigis, Holladay, Hoffer, and SRK/T) was compared and analyzed using differences between the predicted refractive power and actual refractive power at 2 months after cataract surgery. Mean prediction error (ME), mean absolute error (MAE), median absolute error (MedAE), and the percentage of eyes that were within ± 0.50 diopters (D), ± 0.75 D, and ± 1.00 D of the target refraction were calculated for each formula.Results: For all eyes, Haigis formula was the most accurate in MAE, followed by Barrett II formula. Comparing the probability of MAE within 0.50 D, Haigis formula showed the highest accuracy. A total of 20 eyes of 20 patients had more than 25 mm axial length. Regarding MAE, Hoffer Q was the most accurate, followed by the Olsen formula. Comparing the probability of MAE within 0.50 D, the Hoffer Q formula was the most accurate. A total of 24 eyes of 24 patients had more than 46 D keratometry. Regarding MAE and MedAE, Haigis was the most accurate, followed by the Barrett II formula. Comparing the probability of MAE within 0.5 D, Holladay formula was the most accurate.Conclusions: Barrett II and Haigis formulas showed greater accuracy for all patients when we determined IOL power before cataract surgery. Hoffer Q, Olsen, and Barrett II formulas showed higher accuracy for long axial length.

Before the switch, the patient’s best corrected visual acuity of the left eye was 0.4; however, on arrival at the clinic, it was finger count at 10 cm. Suspecting intraocular inflammation and retinal vasculitis caused by brolucizumab, he was treated with both local and systemic steroids and later underwent a vitrectomy. Post-surgery, the patient’s symptoms and vision improved and he received additional anti-vascular endothelial growth factor injections. One year after onset, the corrected vision of his left eye was 0.5 with no observed recurrence of intraocular inflammation.Conclusions: When reactions related to intraocular inflammation associated with brolucizumab are identified, aggressive treatment is crucial.
