PURPOSE: To investigate the retinal vascular abnormalities in both affected and fellow eyes of presumed unilateral Coats' disease patients using ultra-wide-field fluorescein angiography (UWF-FA) and their association with visual prognosis. METHODS: A retrospective review of 30 patients diagnosed with presumed unilateral Coats' disease, evaluated with UWF-FA from March 2003 to May 2024 in a tertiary referral hospital. Clinical features and multimodal imaging findings were evaluated and factors related to final visual outcomes were analyzed...

PURPOSE: To evaluate the surgical outcomes of a modified normogram for bilateral lateral rectus recession (BLR) in the surgical management of intermittent exotropia, with a focus on achieving small overcorrection. METHODS: A retrospective medical chart review of 242 patients who underwent surgery for intermittent exotropia between October 2014 and June 2020 was performed. Our modified normogram reducing amount of recession targeted for small postoperative overcorrection within 5 prism diopters (PD)...

PURPOSE: To investigate the clinical features and visual outcome of infectious keratitis associated with Orthokeratology (Ortho-K) lens in Korean pediatric patients. METHODS: We retrospectively reviewed medical records of patients diagnosed with Ortho-K lens-associated infectious keratitis from June 2005 to April 2020 at a tertiary referral hospital. Patients' demographics, clinical features, microbiological evaluation, and treatment methods were assessed and factors related to final visual outcomes were analyzed...

PURPOSE: To evaluate two-year outcomes of intravitreal aflibercept injection for neovascular age-related macular degeneration (nAMD) treated with 'observe before treat-and-extend' (O-TAE) strategy in the real-world setting. METHODS: This retrospective study included treatment-naïve nAMD patients treated with aflibercept using O-TAE regimen and followed up for more than 2 years. Patients were observed bimonthly to check recurrence after 3 monthly loading injections...

PURPOSE: This study aimed to determine the changes in choroidal thickness induced by pioglitazone in diabetic patients. METHODS: A total of 261 patients diagnosed with type 2 diabetes who had taken oral pioglitazone for more than 6 months were included in the study. After excluding patients who did not undergo regular eye examinations or who had ophthalmic surgery/interventions during the treatment period, a total of 40 eyes were included. The study examined the duration and dosage of pioglitazone, patient age, ocular axial length, refraction, glycated hemoglobin, systolic blood pressure, corrected visual acuity, macular thickness, choroidal thickness, and choroid vascular index...

PURPOSE: To compare changes in the swept-source anterior segment optical coherence tomography (SS AS-OCT) parameters and intraocular pressure (IOP) control after lens extraction in various spectra of primary angle closure disease (PACD). METHODS: A total 92 eyes from 92 patients with PACD who underwent lens extraction were included in the study. All patients underwent IOP measurement preoperatively and postoperatively at 1 day, 1 week, 1 month, 3 months, and 6 months...

PURPOSE: This study aimed to analyze the incidence and characteristics of intraocular lens (IOL) dislocation after cataract surgery in South Korea. METHODS: We retrospectively analyzed the incidence of IOL dislocation after cataract surgery in patients diagnosed between 2002 and 2021. Data of all pseudophakic patients who underwent secondary IOL or IOL exchange surgeries due to IOL dislocation were extracted from the Korean National Health Insurance System (KNHIS) database and the Korean Standard Classification of Diseases-7 codes...

PURPOSE: There has been a lack of data on health-related quality of life (HRQoL) in children with vernal keratoconjunctivitis (VKC) from South East Asia. This study evaluated the levels (mean total score and subscales score) of HRQoL, comparing the VKC and normal children groups, and within the VKC severity groups. METHODS: A cross-sectional study was conducted in two tertiary hospitals, specifically the pediatric ophthalmology services at Hospital Hospital Selayang and Universiti Sains Malaysia, spanning from 2019 to 2020...

PURPOSE: To compare corneal higher order aberrations (HOAs) in patients with epiphora caused by unilateral primary acquired nasolacrimal duct obstruction (PANDO) and their fellow eyes. METHODS: One hundred twenty two eyes of 61 patients with unilateral PANDO were included. Affected eyes named as Group 1 and contralateral eyes named as Group 2. Munk scale and fluorescein dye disappearance test (FDDT) were assessed. Corneal topographic and HOAs measurements were taken by Sirius topography...

PURPOSE: This study aims to evaluate the impact of upper eyelid blepharoplasty on perceived age, attractiveness, success, and overall health as rated by observers. METHODS: A web-based survey was conducted with 203 observers who were unaware of the study's purpose. They assessed pre- and post-operative images of 12 female patients using the Delphi method to ensure appropriate image selection and unbiased ratings. Observers rated the images on a visual analog scale from 0 to 10, where higher scores indicated more favorable perceptions...

PURPOSE: This study aimed to determine the incidence and visual outcomes of pachychoroid neovasculopathy (PNV) in patients initially diagnosed with central serous chorioretinopathy (CSC). METHODS: In this study, 144 patients aged 20-55 years with treatment-naïve chronic CSC, defined as the persistence of subretinal fluid (SRF) for 6 months, were retrospectively enrolled. Patients with PNV at the initial evaluation were categorized as Group 1, whereas those who developed new-onset PNV during follow-up were categorized as Group 2...

PURPOSE: Strabismus in patients with craniosynostosis is common, but surgical correction of strabismus in these patients remains challenging. We report our findings in 6 patients (4 of whom were Korean) with craniosynostosis who underwent strabismus surgery to specifically address V-pattern horizontal strabismus with moderate-to-severe inferior oblique (IO) overaction, using IO myectomy at a single tertiary hospital between 2005 and 2016. Materials and. METHODS: We recorded preoperative characteristics including sex, age, type of strabismus, versions grading, refractive error, and visual acuity...

PURPOSE: To evaluate the outcomes of wavefront-optimized (WFO) and topography-guided (TG) transepithelial photorefractive keratectomy (transPRK) in the treatment of myopia and myopic astigmatism. METHODS: Patients who underwent transPRK using the WaveLight® EX500 excimer laser for the correction of myopia and myopic astigmatism between January 2022 and March 2023 were divided into the WFO transPRK (77 eyes of 36 patients) or TG transPRK (63 eyes of 31 patients) groups in this retrospective, observational cohort study...

PURPOSE: To Investigate the prognostic factors for recurrent rhegmatogenous retinal detachment (RRD) following silicone oil removal. METHODS: This retrospective review included 147 consecutive patients with RRD treated with silicone-oil tamponade at a high-volume referral-based tertiary hospital between January 2012 and May 2022. All patients underwent follow-up for a minimum of 6 months after subsequent silicone oil removal. The primary outcome measure was the rate of recurrent retinal detachment following silicone oil removal, and the secondary outcome was best-corrected visual acuity after silicone oil removal...
