Purpose: We report a case of visual impairment due to circulatory failure in the central retinal artery during blow-out fracture repair.Case summary: A 16-year-old male with no underlying disease was diagnosed with a trapdoor type medial orbital wall blow-out fracture after a motorcycle accident and underwent blow-out fracture repair. During the surgery, his left eye was nearly completely dilated. Postoperatively, the visual acuity in the left eye was hand motion and there was ptosis of the left upper eyelid. Concerned with the possibility of orbital implant compression, computed tomography was performed immediately and a second operation was performed. However, there was no direct compression originating from the intraocular implant or any signs of active bleeding. The following day, optical coherence tomography and fluorescein angiography revealed a cherry-red spot on the central fovea with edema of the inner retinal layer and delayed arterial circulation. Under a diagnosis of incomplete central retinal artery occlusion, the patient was treated with intraocular pressure-lowering eye drops and intravenous mannitol. Despite prompt intervention, the visual acuity of the left eye did not improve beyond 0.04 at the 2-year follow-up.Conclusions: When there is visual impairment and pupillary dilation after blow-out fracture repair, we should consider not only compressive factors but also the possibility of central retinal artery occlusion or circulatory failure. In such cases, retinal examinations should be done to assess the retinal blood flow and enable early detection of any complications allowing prompt appropriate intervention.

Purpose: This study used anterior segment swept-source optical coherence tomography (AS SS-OCT) to explore the effect of temporal decentration within the orthokeratologic lens treatment zone on corneal aberrations.Methods: After lens placement, AS SS-OCT was used to evaluate anterior, posterior, and total corneal astigmatism and the magnitudes of the individual 1st- to 4th-order aberrations of the anterior and entire corneal fields. Also, the 4th-to 7th-order root mean square (RMS), and the low- and high-ordered RMSs of both the anterior and entire corneal areas were recorded. We compared subjects lacking (the no decentration [ND] group) to those exhibiting (the temporal decentration [TD] group) temporal decentration.Results: In all, 61 eyes of 32 patients (44 eyes in the ND group and 17 in the TD group) were included. In the TD group, the average temporal decentration was 0.74 ± 0.15 mm. The baseline axial length, spherical equivalent, anterior mean corneal power, and anterior corneal astigmatism did no difference between the two groups. However, the TD group exhibited more anterior and total corneal horizontal tilts, and horizontal coma, than the ND group. That group also had less with-the-rule (WTR)/against-therule (ATR) astigmatism, elevated anterior and total corneal 5th-order RMS values, and greater low- and high-ordered RMS levels. However, despite these differences, the extent of myopia correction did not significantly differ between the groups.Conclusions: Although myopia reduction was not significantly compromised by temporal decentration of an orthokeratologic lens, the anterior and total corneal low- and high-ordered RMS values increased. In terms of individual aberrations, the low-ordered horizontal tilt and the high-ordered horizontal coma increased.

Purpose: We evaluated the factors associated with the development and progression of retinoschisis in patients with myopic choroidal neovascularization (CNV) treated with intravitreal bevacizumab injections.Methods: We conducted a retrospective analysis of 54 eyes with myopic CNV treated with intravitreal bevacizumab injections. We compared optical coherence tomography findings at baseline and final follow-up visits to assess the occurrence and progression of retinoschisis. Furthermore, we analyzed potential risk factors associated with the occurrence and progression of retinoschisis.Results: During a mean follow-up of 42.82 ± 27.12 months, retinoschisis worsened in 11 eyes (20.3%), including 7 eyes with new-onset disease and 4 with progression. The aggravated group demonstrated a significantly longer baseline axial length compared to the non-aggravated group (31.21 ± 2.52 μm vs. 29.21 ± 1.64 μm, p = 0.011). Univariate logistic regression analysis identified axial length (p = 0.041) and pre-existing outer retinoschisis (p = 0.018) as potential predictors of retinoschisis aggravation. In a multivariate analysis, axial length remained significantly associated with retinoschisis aggravation (p = 0.038, odds ratio = 2.63).Conclusions: Our study emphasized that a longer axial length is a risk factor for the development or progression of retinoschisis in myopic CNV patients treated with intravitreal bevacizumab injections. Therefore, closer monitoring during treatment may be warranted for myopic CNV patients with long axial length at baseline.

Purpose: We present a case of Colletotrichum jasminigenum (C. jasminigenum)-induced Infectious sclerokeratitis.Case summary: An 81-year-old patient presented to our hospital with left eye pain and decreased vision that had started 7 days prior. He had a history of left eye pterygium excision a decade earlier. Examination using a slit lamp revealed a nasal conjunctival defect, scleral melting, deep stromal infiltration with a feathery margin, and hypopyon. Considering the suspicion of fungal sclerokeratitis, we performed a smear analysis and potassium hydroxide (KOH) and culture testing. The KOH test revealed hyphae, leading to systemic fluconazole and topical fluconazole and natamycin. Subsequently, we performed surgery, including debridement of the necrotic scleral area, conjunctival rotation and scleral grafting, and anterior chamber irrigation with intracameral and intravitreal voriconazole injections, due to progressive corneal infiltration and scleral melting. Additionally, we switched to using systemic and topical voriconazole. The culture yielded fungi, with DNA sequencing confirming C. jasminigenum as the causative agent. Following treatment, the lesion improved, and no signs of recurrence were observed.Conclusions: Voriconazole is an effective treatment for C. jasminigenum-induced fungal sclerokeratitis.

Purpose: This report presents a case of repeated toxic conjunctival necrosis caused by amikacin eye drops in a patient with a corneal ulcer induced by Mycobacterium abscessus (M. abscessus).Case summary: During treatment for herpetic keratitis with complaints of conjunctival hyperemia and eye pain in the right eye for 1 month. Slit-lamp microscopy revealed a circular corneal epithelial defect and stromal infiltration of her right eye. Gram staining and culture were performed, and eye drops were prescribed for empirical treatment. The bacterial culture grew M. abscessus. Antibiotic susceptibility tests showed resistance to quinolone. The patient was prescribed amikacin eye drops and the corneal epithelial defects improved. Two weeks later, circular conjunctival epithelial defects and hyperemia were observed on the inferior conjunctiva. Conjunctival necrosis caused by amikacin was suspected. The amikacin eye drops were discontinued and the conjunctival lesion improved. However, the patient’s corneal ulcer recurred. The amikacin eye drops were restarted, but conjunctival toxicity recurred, so she was treated with topical clarithromycin and moxifloxacin. The eye drops were gradually reduced and the lesion healed leaving mild corneal opacity.Conclusions: M. abscessus-induced keratitis resistant to quinolone antibiotics requires long-term combined therapy with multiple drugs. Amikacin eye drops should be used carefully as conjunctival toxicity may occur.

Purpose: To assess the impact of toxoplasma immunoglobulin G (IgG) titers on the diagnosis of active ocular toxoplasmosis.Methods: We retrospectively analyzed the medical records of patients tested for toxoplasma IgG at our uveitis clinic. Active ocular toxoplasmosis was clinically diagnosed based on wide-angle fundus photography and disease progression. Patients with IgG titers ≥ 30 IU/mL were classified as seropositive-high titer, those with IgG titers of 1.6-30 IU/mL as seropositive-low titer, and the remaining patients as seronegative. We compared the proportion of active ocular toxoplasmosis among these groups. Additionally, we evaluated the sensitivity and specificity of each titer and attempted to determine an ideal reference titer for toxoplasma IgG in diagnosing active ocular toxoplasmosis.Results: Out of 824 patients, 86 (10.4%), 88 (10.7%), and 650 (78.9%) were categorized as seropositive-high titer, seropositivelow titer, and seronegative, respectively. Among these patients, 34 in the seropositive-high titer group and 2 in the seropositive- low titer group were clinically diagnosed with active ocular toxoplasmosis. The false-positive rate was significantly different between the groups, being 60.5% in the seropositive-high titer group and 97.7% in the seropositive-low titer group (p < 0.001). The receiver operating characteristic curve indicated that 37.70 IU/mL could be an ideal reference titer for diagnosing ocular toxoplasmosis.Conclusions: The false-positive rate was notably lower (60.5%) in patients with IgG titers ≥ 30 IU/mL compared to those with titers of 1.6-30 IU/mL (97.7%). Therefore, not only the presence of IgG but also the level of titer appears to be important in diagnosing ocular toxoplasmosis.

Purpose: We evaluated a novel surgical technique for managing the intraocular lens (IOL) through in situ scleral fixation and its outcomes.Case summary: This retrospective case series included three eyes of three patients treated with the in situ scleral fixation technique for IOL. Our method involves suturing the haptics of an already intraocularly injected IOL in situ using a Siepser sliding knot suture, while the other haptic is tied externally. Notably, no intraoperative or postoperative complications, such as cystoid macula edema, were observed.Conclusions: This novel technique is a user-friendly and effective approach to improve IOL-capsular bag stability, requiring minimal intraocular intervention or preoperative preparation compared to conventional IOL scleral fixation methods. Furthermore, it is particularly effective for addressing concerns related to IOL-capsular bag stability following IOL insertion, as it eliminates the possibility of performing the typical IOL scleral fixation due to the absence of preoperative preparation and evaluation.

Purpose: This study explored the types and incidences of adverse ophthalmic adverse events after COVID-19 vaccination and their associations with such vaccination in patients who presented to the sole local, tertiary, general hospital in region Ulsan of South Korea complaining of ophthalmic discomfort after COVID-19 vaccination.Methods: This cross-sectional study was conducted at Ulsan University Hospital, which is the only tertiary general hospital in Ulsan city. All participants visited the hospital from March 2021 to August 2022 complaining of ophthalmic discomfort after COVID-19 vaccination. Clinical variables were collected from both our clinical data warehouse and the electronic medical records of the hospital.Results: To date, 2,766,569 COVID-19 vaccine doses have been administered in Ulsan city. A total of 97 cases of vaccination-related adverse ophthalmic events have been confirmed. In 21 of these cases, irreversible sequelae persisted after the side-effects. Most symptoms developed within 1 week after vaccination (mean 5.06 ± 6.86 days). The most common symptom was visual disturbance (67 cases), followed by ocular pain (19 cases) and double vision (16 cases). The most frequent diagnoses associated with irreversible sequelae were neurological diseases (7 cases), retinal diseases (5 cases), and glaucoma (5 cases). The frequencies of side effects were highest for those of BNT162b2 status (34 cases), followed by those of ChAdOx1 (30), mRNA-1273 (20), and Ad26.COV2.S (4).Conclusions: In contrast to other vaccinations, COVID-19 vaccination was viewed as urgent; a few known ophthalmic side effects developed after vaccination. Although such adverse events are rare, affected patients must be closely monitored; the sequelae may be irreversible.

The frequencies of side effects were highest for those of BNT162b2 status (34 cases), followed by those of ChAdOx1 (30), mRNA-1273 (20), and Ad26.COV2.S (4).Conclusions: In contrast to other vaccinations, COVID-19 vaccination was viewed as urgent; a few known ophthalmic side effects developed after vaccination. Although such adverse events are rare, affected patients must be closely monitored; the sequelae may be irreversible.","PeriodicalId":504314,"journal":{"name":"Journal of the Korean Ophthalmological Society","volume":"54 s55","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140700224","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 compared the efficacy of focal laser photocoagulation and intravitreal bevacizumab injection in the treatment of chronic central serous chorioretinopathy.Methods: We conducted a retrospective analysis involving 46 eyes of 46 patients with chronic central serous chorioretinopathy who received focal laser photocoagulation (22 eyes) or intravitreal bevacizumab injection (24 eyes). Changes in best-corrected visual acuity (BVCA), central macular thickness, and rates of complete subretinal fluid (SRF) resolution and recurrence were compared over a 6-month period.Results: Although the focal laser photocoagulation and intravitreal bevacizumab injection groups demonstrated a significant reduction in central macular thickness at 6 months (p < 0.001), no statistically significant differences were observed between these groups at the end of the follow-up period. Notably, a gradual improvement in BVCA was observed in both groups following initial treatment, with significant improvement seen at 6 months (p = 0.049 and p = 0.048 for the laser and injection groups, respectively). However, no statistically significant difference in BVCA improvement was observed between the groups. Complete SRF resolution was achieved in 22 eyes in the laser group and 23 eyes in the injection group. Although recurrence of SRF was observed in 9 and 13 eyes in the laser and injection groups, respectively, there was no statistically significant difference between the groups (p = 0.229).Conclusions: Focal laser photocoagulation and intravitreal bevacizumab injection significantly improved anatomical and visual acuity outcomes in patients with chronic central serous chorioretinopathy. Although focal laser photocoagulation was associated with more rapid visual recovery and a lower recurrence rate compared to intravitreal bevacizumab injection, further studies are needed to evaluate its potential complications.

Purpose: To describe a case of bilateral serous retinal detachment in a patient with multiple myeloma.Case summary: A 75-year-old woman presented with sudden-onset of reduced visual acuity in both eyes which had begun 2 days prior. Initial ophthalmological assessment revealed that visual acuities were 0.03 in the right eye and 0.05 in the left eye. Optical coherence tomography indicated pronounced macular elevation and extensive subretinal fluid accumulation in the posterior pole of both eyes. Fluorescein angiography did not detect any significant vascular leakage. Blood tests showed an albumin level of 2.1 g/dL, and plasma protein electrophoresis revealed an M protein level of 0.19 g/dL. Multiple myeloma-related hypoalbuminemia and paraprotein were suspected. The patient's retinal statuses were closely monitored and compared with blood test outcomes. Over 2 months, there was significant improvement, characterized by decreasing macular elevation and reduction of subretinal fluid. This progress was sustained thereafter. Plasma protein electrophoresis showed a gradual decline in paraproteins which coincided with the amelioration of serous retinal detachment.Conclusions: We encountered a case of acute and extensive serous retinal detachment in both eyes of a patient with multiple myeloma. When fluorescein angiography does not definitively show vascular leakage, light chain deposition disease-related serous retinal detachment should be considered. In such instances, it is important to address and monitor the underlying multiple myeloma.
