Incidence and Risk Factors of Recurrent Anterior Uveitis in Initial Acute-Onset Vogt-Koyanagi-Harada Disease

Purpose@#We report the estimated incidence of, and risk factors for, recurrent anterior uveitis in patients with initial acute-onset Vogt-Koyanagi-Harada (VKH) disease using survival analyses. @*Methods@#Patients who were diagnosed with initial acute-onset VKH disease during 2003–2022 at two university hospitals were included. Recurrent anterior uveitis was defined as the first occurrence of the granulomatous anterior uveitis with anterior chamber cells and flare of 2+ or more by the Standardization of Uveitis Nomenclature (SUN) Working Group grading scheme, after the disappearance of conspicuous uveitis and serous retinal detachment for at least 3 months, regardless of systemic or local treatment. The univariate log-rank test and multivariate Cox regression analyses were performed, including patients’ demographic characteristics, underlying diseases, presence of prodromal symptoms, duration of visual symptoms, visual acuity, slit-lamp and fundus findings, and height of serous retinal detachment. The treatment method and response to treatment were also included. @*Results@#The estimated incidence was 39.3% at 10 years. Fifteen of 55 patients (27.3%) had recurrent anterior uveitis during the mean follow-up of 4.5 years. The presence of focal posterior synechiae at the diagnosis increased the risk of recurrent anterior uveitis 6.97-fold compared to the absence of synechiae (95% confidence interval [CI], 2.20–22.11; p < 0.001). Use of systemic high-dose steroid therapy more than 7 days after the development of visual symptoms resulted in a hazard ratio of 4.55 (95% CI, 1.27–16.40; p = 0.020). @*Conclusions@#This study reports the estimated incidence and risk factors of recurrent anterior uveitis in VKH disease from survival analyses. However, because of the retrospective nature of this study, it is hard to confirm the consistency of the medical records regarding risk factors, thus, the presence of focal posterior synechiae can be inconclusive as a risk factor. Further studies are warranted.

Comparison of Corneal Higher-order Aberrations Measured by Scheimpflug Camera and Placido Disc-based Topography in Korean Patients

Purpose@#We compared corneal higher-order aberration (HOA) measurements between the Pentacam® HR (PC), which uses the Scheimpflug principle, and the iTraceTM aberrometer (IT), which evaluates Placido disc topography. @*Methods@#We retrospectively analyzed 109 eyes of 87 patients without a history of ocular surface disease during the period from January 2021 to December 2022; both devices were used on the same day. 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 compared by Bland-Altman plots for agreement analysis and Pearson correlation coefficient for correlation analysis. @*Results@#There was no significant difference in the total HOA (p = 0.145), coma (p = 0.309), or secondary astigmatism (p = 0.080) between the PC and IT measurements; all other HOAs significantly differed between devices (p < 0.001). In the correlation analysis, the total HOA (r = 0.605, p < 0.001) and coma (r = 0.634, p < 0.001) were moderately correlated between the two devices; the other HOAs showed low degree of correlations. In the Bland-Altman plot analysis, all HOAs showed low agreement between the two devices. @*Conclusions@#Corneal total HOA and coma measured by the two devices were significantly correlated between the two devices, but other HOAs showed significant differences in measurement and low correlations. Therefore, corneal HOA measurements cannot be interpreted interchangeably between the two devices.

Compressive Optic Neuropathy Caused by Internal Carotid Artery Aneurysm Presenting with Concurrent Neuromyelitis Optica

Purpose@#To report a case of compressive optic neuropathy caused by an internal carotid artery aneurysm accompanied by concurrent neuromyelitis optica (NMO).Case summary: A 48-year-old female presented with sudden painless blurry vision in the inferior visual field of her right eye for 2 days. The corrected visual acuity was 0.7 in the right eye, and a relative afferent pupillary defect was observed. The visual field test demonstrated an inferior altitudinal defect in the right eye, while the color vision test was normal. However, after 5 days, she developed decreased color vision. Optic nerve enhancement in the right eye was observed on orbital magnetic resonance imaging, and anti-aquaporin-4 antibody was positive. She was diagnosed with NMO, and high-dose steroids were administered intravenously. In addition, brain magnetic resonance angiography showed a 5-mm aneurysm in the ophthalmic segment of the right internal carotid artery, which was compressing the optic nerve. Coil embolization of the aneurysm was performed. On the fourth day of steroid therapy and the first day after coiling, the corrected visual acuity in the right eye improved to 1.0. At 6-week follow-up, color vision and visual field defect also showed complete recovery. @*Conclusions@#In this rare case of internal carotid artery aneurysm combined with NMO, early active treatment led to complete recovery of visual acuity and field defects.

A Case of Choroidal Folds in a Patient with Immunoglobulin G4-related Ophthalmic Disease

Purpose@#To report a case of choroidal folds caused by enlargement of the extraocular muscles (EOM) and orbital fat in a patient with immunoglobulin (Ig) G4-related ophthalmic disease. A full recovery was achieved after steroid administration.Case summary: A 56-year-old male received intravenous high-dose steroids to treat IgG4-related ophthalmic disease presenting with bilateral eyelid edema, hypertrophy of all EOM, and mild exophthalmos. After 3 months, only slight improvement was observed and azathioprine was initiated. The patient exhibited only a minimal response over the next 2 months; all medications were therefore stopped. One month later, the patient presented with aggravation of the swelling (both eyelids), exophthalmos, and visual impairment of the left eye. The corrected vision was 1.0 in the right eye and 0.2 in the left eye; choroid folds were observed in the posterior pole of the left eye. Intravenous steroid (500 mg) was given once and oral steroids prescribed as maintenance therapy. After 2 weeks, the corrected visual acuity recovered to 1.0 in both eyes, the eyelid edema and exophthalmos improved and the choroidal folds resolved completely. @*Conclusions@#Choroidal folds associated with enlargement of EOM and orbital fat tissue can cause visual impairment in patients with IgG4-related ophthalmic disease. Steroids are effective in the acute phases and prevent irreversible visual impairment.

A Case of Iris Neovascularization in Severe Fungal Keratitis Treated with Intracameral Bevacizumab

Purpose@#We report a case in which iris neovascularization (NVI) improved after intracameral bevacizumab injection in a patient who exhibited fungal keratitis with NVI.Case summary: A 47-year-old man experienced a tree branch-induced injury to his right eye and was treated for keratitis for 1 month. However, his condition deteriorated and he was referred to our hospital. Initial slit lamp biomicroscopy findings showed a large, thick central deep stromal infiltration with a concentric circle shaped feathery-like margin, epithelial defect, satellite lesion, fungal ball, hypopyon, and NVI. Aspergíllus fumigatus was isolated in the corneal scraping culture. Amphotericin B, voriconazole, and natamycin were administered as topical treatment along with systemic amphotericin B. After treatment, the corneal lesions gradually improved, but NVI worsened. After the 5th week, total hyphema occurred; anterior chamber irrigation and intracameral bevacizumab injection were performed. Two weeks postoperatively, the NVI exhibited complete regression; corneal stromal melting with descemetocele appeared after 8 weeks. Penetrating keratoplasty was performed and NVI was no longer observed at 6 months after surgery. @*Conclusions@#For the treatment of iris neovascularization in patients with infectious keratitis, intracameral bevacizumab injection at an appropriate time may be effective.

One-and-a-half Syndrome Associated with Multiple Sclerosis in a 14-year-old Girl

Purpose@#To report the case of a 14-year-old female patient with one-and-a-half syndrome subsequently diagnosed with multiple sclerosis involving the pons.Case summary: A 14-year-old girl without any underlying disease presented with difficulty focusing and mild headache for 5 days. The patient showed conjugate gaze palsy to the left, limited adduction in the left eye, and abducting nystagmus in the right eye, which indicated one-and-half syndrome. T2 fluid-attenuated inversion recovery brain magnetic resonance imaging revealed multiple punctate hyperintensities in the pontine tegmentum, bilateral cerebral white matter, and cerebellum. Cerebrospinal fluid examination revealed oligoclonal bands and multiple sclerosis was diagnosed. The patient was treated with intravenous steroids and beta-interferon. Seven weeks later, limitation of eyeball movement and nystagmus had resolved completely. @*Conclusions@#At the young age of 14 years, a patient presenting with one-and-a-half syndrome was diagnosed with multiple sclerosis. Children with multiple sclerosis may experience severe physical and cognitive impairments, and brainstem involvement predicts an especially poor prognosis. Early diagnosis and active treatment may help to prevent poor outcomes.

A Comparison of Intravaginal Misoprostol with Oral Dinoprostone for Labor induction at Term / 대한산부인과학회잡지

OBJECTIVE: To compare the safety and efficacy of intravaginal misoprostol versus oral dinoprostone for labor induction at term. METHODS: One hundred of patients at term were randomized to receive either 50microgram of misoprostol vaginally every 4 hours or dinoprostone 0.5mg orally every 1 hour for the maximum of six doses. Intravenous infusion of oxytocin was administered under such circumferences as the patient did not go into active labor after maximum dose, SROM was developed without an adequate contraction pattern, or the patient had arrest of dilatation(no change in cervical dilatation for 2 hours). We compared the frequency of oxytocin augmentation, administration to delivery interval, vaginal delivery rate within 12 hours and 24 hours, intrapartum complications, induction failure, mode of delivery, neonatal outcomes, and maternal complications between two groups. RESULTS: The average interval from administration to delivery was shorter in the misoprostol group(739.4+/-372.4min vs 1087.7+/-765.1min, p<0.05), but the interval from administration to vaginal delivery of each group was similar(724.3+/-375.4min vs 800.3+/-697.0min). Regarding the frequency of vaginal delivery within 24 hours, however, misoprostol group was higher than dinoprostone group(88% vs 56%, p<0.001). And oxytocin augmentation of labor occurred less commonly in misoprostol group than in dinoprostone group(20% vs 76%, p<0.05). Any statistically significant difference in intrapartum complications, mode of delivery, and neonatal or maternal adverse outcome was not appeared between these two group. CONCLUSION: Vaginal misoprostol is as effective and safe as oral dinoprostone for cervical ripening and induction of labor at term. In addition, vaginal misoprostol contributes the curtailment of labor induction expenditure due to its moderate price; misoprostol costs 100 won per 50microgram.

A Case of Pelvic and Abdominal Actonomycosis Associated with an Intrauterine Contraceptive / 대한산부인과학회잡지

Actinomycosis is a rare entity which presents some difficulties in establishing a correct preoperative diagnosis. Many actinomycotic pelvic infections in women are related to IUD use and the colonization rate appears to increase in accordance with the duration of IUD use. So, all women in IUD use are recommended to make cervicovaginal smear and pelvic infection associated with IUD use should be suspected to have actinomycoses. We report a case which presented painful mass on right upper and lower quadrant of abdomen of a 40-year-old women. We identified sulfur granules by histopathologic exam of surgically resected specimen. Eventually it proved to be pelvic and abdominal actinomycosis associated with the use of an intrauterine device. Because variable clinical pictures and infrequency of the disease make the diagnosis more difficult, increased alertness of clinicians and microbiologists to the presence of anaerobic organism as the cause of infection are needed to make an earlier and more correct diagnosis of actinomycoses and to further avoid any inappropriate treatment.
