Purpose: We report the diagnosis and treatment of a secondary iris cyst in a patient referred for an iris tumor.Case summary: A 29-year-old man diagnosed with an anterior chamber mass of the left eye was referred to our center for further evaluation and management. Twenty years previously, he suffered a penetrating ocular injury of his left eye and underwent primary closure. He had no underlying systemic disease. At his initial visit, the best corrected visual acuity of his left eye was 0.5. A whitish-gray mass was observed within the anterior chamber from 1 o'clock to 5 o'clock, obscuring the pupil. Anterior segment optical coherence tomography revealed a cystic mass touching the retrocorneal surface. No other lesions were seen on orbital imaging or ocular ultrasonography. Ultimately, it was diagnosed as an iris cyst that occurred secondary to ocular trauma. After needle aspiration and intracystic injection of 99% ethanol, the cyst collapsed fully. However, a cataract developed within a few months, and phacoemulsification and intraocular lens implantation were performed. Seven months after cyst aspiration, the uncorrected visual acuity of the left eye had recovered to 0.5. The cyst still adhered to the corneal endothelium, remaining in its collapsed state. The current corneal endothelial cell density is 871 cells/mm2.Conclusions: A secondary iris cyst was diagnosed in a patient with a history of penetrating eye trauma and surgery. It was treated successfully with needle aspiration and intracystic alcohol injection.

Purpose: We report two cases of non-arteritic ischemic optic neuropathy (NAION) following extracorporeal membrane oxygenation (ECMO) treatment.Case summary: (Case 1) A 36-year-old man underwent ECMO treatment. Upon regaining consciousness, he complained of a darkened peripheral visual field and was subsequently referred to an ophthalmologist. His best-corrected visual acuity was 0.9 in the right eye and 0.8 in the left eye. The intraocular pressure measured 12 mmHg in the right eye and 10 mmHg in the left eye; color vision was normal. A visual field test demonstrated concentric visual field defects in both eyes, and a fundus examination revealed a pale optic disc. Optical coherence tomography (OCT) indicated a decrease in retinal nerve fiber layer (RNFL) thickness. (Case 2) A 48-year-old woman underwent ECMO treatment. After regaining consciousness, she reported decreased vision in her right eye. Her best-corrected visual acuity was limited to hand motion in the right eye and was 1.2 in the left eye. A relative afferent pupillary defect in the right eye was observed. Color vision in the right eye was compromised, and a fundus examination revealed a pale optic disc. A visual field test demonstrated total visual field defect in the right eye, while OCT showed decreases in both the RNFL thickness and the ganglion cell-inner plexiform layer thickness of the right eye. Magnetic resonance imaging (MRI) revealed high signal intensity and abnormal enhancement in the right retrobulbar optic nerve.Conclusions: In cases where vision loss and visual field defects are observed following ECMO treatment, differential diagnoses for ischemic optic neuropathy are warranted.

Purpose: To report the long-term clinical outcomes of non-surgical treatment involving prosthetic eye wear in patients diagnosed with congenital microphthalmos.Methods: A retrospective review of the medical records of 20 patients was conducted. In total, 21 eyes were diagnosed with congenital microphthalmos between May 2008 and December 2022 at Seoul St. Mary’s Hospital in Korea.Results: This study included 20 patients (12 males and 8 females) with an average age of 4 months at diagnosis. The observed ophthalmic anomalies included two cases of congenital cataract, one of posterior embryotoxon, one of corneo-iris strand, four of iris coloboma, five of central corneal opacity, one of Peter's anomaly, and one of retrobulbar cyst. Accompanying systemic abnormalities were noted, such as lateral ventricle atrophy, corpus callosum atrophy, patent ductus arteriosus, atrial septal defect, and developmental language disorder. Genetic anomalies included anti SS-A/Ro antibody positivity, a 1:100 titer of anti-nuclear antibody, and a PAX6 mutation identified through next-generation sequencing. No specific family histories or pregnancy-related factors were noted. The average follow-up duration was 5.94 years (range: 1 month to 18 years), the average corneal diameter was 4.6 mm, the average axial length was 17.44 mm, the average age for first artificial eye trial was 5.96 years (range: 7 months to 19 years), and the average interval for artificial eye replacement was 22 months (range: 4 months to 5 years and 8 months).Conclusions: Twenty patients with congenital microphthalmos underwent gradual expansion of their prosthetic eyes by regular replacement and size increase without severe complications. This approach led to aesthetically and emotionally positive outcomes for the patients.

Purpose: We evaluated the accuracy and usefulness of self-assessment of visual acuity (VA) using a smartphone application for Korean users and explored its potential application in screening eye diseases.Methods: In total, 52 participants aged ≥ 20 years were included in the study. Of these participants, 31 used Jin Yong-Han’s VA chart and the smartphone application to measure their distant visual acuity (DVA), whereas 21 used Han Chun-Seok’s near visual acuity chart and the application to measure their near visual acuity (NVA). The results and time required for VA measurement using both methods were compared. VA was converted to logarithm of the minimum angle of resolution (logMAR) for analysis. The voice recognition rate of the application for numbers 2-9 was assessed.Results: The mean NVA was 0.29 ± 0.28 using Han’s chart and 0.30 ± 0.43 using the application with no significant difference (p = 1.00). The mean DVA was 0.19 ± 5.89 using Jin's chart and 0.20 ± 0.27 using the application with no significant difference (p = 0.19). The average time spent for measuring NVA and DVA was 19 seconds (s) using Han’s and Jin's charts, whereas it was 42 and 38 s for measuring NVA and DVA using the application. The voice recognition rate of the application was 87% on average for numbers 2-9, with the highest rate for number 7 (79%) and the lowest rate for number 4 (91%).Conclusions: Self-assessment of VA using a smartphone application exhibited similar results to conventional VA measurement methods. Although the measurement time varied, DVA and NVA could be measured at home using a smartphone, and would be particularly useful for those who have difficulty visiting a hospital.
目的：我们评估了韩国用户使用智能手机应用程序自我评估视力（VA）的准确性和实用性，并探讨了其在眼病筛查中的潜在应用：研究共纳入了 52 名年龄≥ 20 岁的参与者。其中，31 人使用 Jin Yong-Han 的视力表和智能手机应用程序测量远视力（DVA），21 人使用 Han Chun-Seok 的近视力表和应用程序测量近视力（NVA）。比较了两种方法的测量结果和所需时间。VA 被转换成最小分辨角的对数（logMAR）进行分析。此外，还评估了应用程序对数字 2-9 的语音识别率：结果：使用 Han 图表的平均 NVA 为 0.29 ± 0.28，而使用应用程序的平均 NVA 为 0.30 ± 0.43，两者无显著差异（p = 1.00）。使用金氏图表的 DVA 平均值为 0.19 ± 5.89，而使用应用程序的 DVA 平均值为 0.20 ± 0.27，两者无明显差异（p = 0.19）。使用韩氏和金氏图表测量 NVA 和 DVA 的平均时间为 19 秒（s），而使用应用程序测量 NVA 和 DVA 的平均时间分别为 42 秒和 38 秒。应用软件对 2-9 号的语音识别率平均为 87%，其中 7 号的识别率最高（79%），4 号的识别率最低（91%）：结论：使用智能手机应用程序对 VA 进行自我评估的结果与传统的 VA 测量方法相似。虽然测量时间各不相同，但在家中使用智能手机就能测量 DVA 和 NVA，这对那些不方便去医院的人尤其有用。

Purpose: To evaluate the effectiveness of an instrument devised for slit-lamp examination of donor corneas suspended in preservation medium.Methods: The study examined two donor corneas received at Yeouido St. Mary's Hospital in February 2023 and March 2023. The instrument has three main components: a plastic holder to hold the preservation medium bottle, a cube with a mirror for reflecting the slit beam, and a stand to attach the device to the slit-lamp. Using the instrument, the donor corneas were examined via slit-lamp: microscopy with the endothelium facing upward and downward. Specular microscopy and anterior segment optical coherence tomography (OCT) were also performed on the preserved donor corneas.Results: Slit-lamp examination of donor corneas in preservation medium using the instrument showed overall corneal buttoning and optical sections of the donor cornea. Using specular reflection and retroillumination, the endothelial layer was partially visible. However, specular microscopy and anterior segment OCT could not examine the donor cornea in preservation medium using the instrument.Conclusions: The devised instrument facilitates slit-lamp examination of donor corneas in preservation medium, enabling a qualitative assessment of donor corneas before corneal transplantation surgery.

Purpose: To report two instances of retinal arterial occlusive vasculitis following intravitreal injection of brolucizumab.Case summary: Two patients noted decreased visual acuity approximately one month after receiving intravitreal brolucizumab injections to treat wet age-related macular degeneration. In case 1, an 85-year-old male reported a reduction in visual acuity in his left eye, declining from a Snellen measurement of 0.2 to hand motion. In case 2, a 70-year-old female experienced a decline in visual acuity in her right eye from 0.4 to finger count at 50 cm. Both patients presented with anterior chamber reactions, and fluorescein angiography demonstrated delayed retinal artery filling time, leading to the diagnosis of retinal occlusive vasculitis. They were treated with both topical and systemic corticosteroids. For case 1, a subsequent vitrectomy was performed to remove the inflammatory membrane located behind the intraocular lens. However, despite aggressive interventions, neither patient showed visual improvement.Conclusions: Retinal occlusive vasculitis, which can result from intraocular inflammation, may occur after intravitreal brolucizumab injection. This condition can lead to significant visual impairment even with aggressive treatment.

Purpose: To investigate the association of the preoperative fat-to-orbit ratio on the outcome of endoscopic orbital decompression in patients with thyroid-associated orbitopathy (TAO).Methods: Between January 2021 and December 2022, 36 patients with TAO, 72 eyes in total, underwent endoscopic orbital decompression at our hospital’s ophthalmology department. We calculated fat-to-orbit ratios using two-dimensional facial computed tomography scans, and conducted both preoperative and postoperative measurements of proptosis and the prism cover test. We used binominal logistic regression analysis to examine the correlation between the ratios and postoperative complications (diplopia, strabismus, lid retraction) following the surgery. Furthermore, simple linear regression analysis was used to assess the relationship between the ratios and change in exophthalmos.Results: The regression indicated significant associations between the ratio and the onset of postoperative complications such as new-onset postoperative diplopia (NOPD) (β = -0.098, p = 0.029), postoperative strabismus (β = -0.123, p = 0.009), and eyelid retraction (β = -0.188, p = 0.002), particularly in cases requiring subsequent strabismus or eyelid retraction surgery after the initial procedure.Conclusions: The preoperative fat-to-orbit ratio is a significant predictor of postoperative complications such as NOPD, strabismus surgery and eyelid retraction surgery in patients undergoing endoscopic orbital decompression for thyroid eye disease. Therefore, it should be considered a valuable indicator of surgical outcomes and complications in such patients.

We calculated fat-to-orbit ratios using two-dimensional facial computed tomography scans, and conducted both preoperative and postoperative measurements of proptosis and the prism cover test. We used binominal logistic regression analysis to examine the correlation between the ratios and postoperative complications (diplopia, strabismus, lid retraction) following the surgery.

Purpose: To report a case of mucosa-associated lymphoid tissue lymphoma (MALToma) that presented as a lacrimal caruncular granuloma.Case summary: A 38-year-old woman presented with a mass in the right lacrimal caruncle and had a history of incision and drainage. Examination revealed a 4-mm elevated mass at the lacrimal caruncle, which resembled a granuloma. The mass was excised under local anesthesia and a MALToma was diagnosed based on the histopathological examination.Conclusions: Although rare, a MALToma can present as a granuloma-like lacrimal caruncular mass. Excision and biopsy of the lacrimal caruncular mass are essential to obtain a definitive diagnosis.

Purpose: To investigate the effects of latanoprostene bunod (LBN) on nitric oxide (NO) production and permeability in human trabecular meshwork cells (HTMC).Methods: HTMC were treated with 50 and 100 µM LBN and latanoprost free acid (LAT) for 30 minutes. Additionally, 100 µM LBN was co-exposed to 0.5 mM L-NAME (N-Nitroarginine methyl ester). Cellular viability and NO production were measured using MTT (3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide) and Griess assays. The permeability and resistance of the HTMC monolayer were evaluated by trans-endothelial electrical resistance (TEER) and carboxyfluorescein permeability.Results: Exposure to 100 µM LBN led to increased NO production, whereas co-exposure to L-NAME reduced NO production. Treatment with 100 µM LBN decreased the TEER of the HTMC monolayer. LBN exposure heightened carboxyfluorescein permeability, but co-exposure to 100 µM LBN and L-NAME reduced permeability. LAT treatment did not affect NO production or permeability.Conclusions: LBN increased the permeability of the HTMC monolayer and increased NO production. Therefore, LBN might increase trabecular outflow in addition to promoting uveoscleral outflow.
目的：研究拉坦前列腺素布诺（LBN）对人小梁网状细胞（HTMC）一氧化氮（NO）产生和通透性的影响。方法：用 50 µM 和 100 µM LBN 和游离酸（LAT）处理 HTMC 30 分钟。此外，100 µM LBN 与 0.5 mM L-NAME（N-硝基精氨酸甲酯）同时暴露。使用 MTT（3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium溴化物）和 Griess 试验测定细胞活力和 NO 的产生。通过跨内皮电阻（TEER）和羧基荧光素渗透性评估了 HTMC 单层的渗透性和电阻：结果：暴露于 100 µM LBN 会导致 NO 生成增加，而同时暴露于 L-NAME 则会减少 NO 生成。100 µM LBN 可降低 HTMC 单层的 TEER。暴露于 LBN 会增加羧基荧光素的通透性，但同时暴露于 100 µM LBN 和 L-NAME 会降低通透性。LAT 处理不会影响 NO 的产生或通透性：结论：LBN 增加了 HTMC 单层的通透性并增加了 NO 的产生。因此，除了促进葡萄膜巩膜外流外，LBN 还可能增加小梁外流。
