Objectives: We investigated the prevalence of anti-thyroid autoantibodies and thyroid dysfunction, and their association with clinical and laboratory features in Korean patients with primary Sjögren's syndrome (pSS) without overt thyroid illnesses.
Methods: We consequently included 196 pSS patients (190 women) and cross-sectionally collected clinical and laboratory data including the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) and Patient Reported Index (ESSPRI). The fatigue-dominant group was defined as those in the highest quartile of the fraction of fatigue, calculated as the ESSPRI fatigue score divided by the total ESSPRI score.
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-related 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.
Importance: Taking ω-3 supplements has been associated with a reduction in symptoms of dry eye disease (DED) associated with meibomian gland dysfunction (MGD). However, a recent relatively large clinical trial concluded that treating DED with ω-3 consumption was ineffective, potentially warranting additional investigations.
Objectives: To investigate the effect of re-esterified triglyceride (rTG) ω-3 fatty acid supplementation on DED associated with MGD.
Purpose: This study assessed post-market clinical outcomes of the Clareon monofocal intraocular lens (IOL) preloaded in the AutonoMe Delivery System in a real-world setting of Korean patients.
Methods: This prospective, multicenter, single-arm study in Korea was conducted from July 2020 to December 2021. Patients were ≥20 years old with unilateral or bilateral cataracts who received Clareon IOLs (CNA0T0) preloaded in an automated injector system.
Purpose: To compare the posterior capsule rupture (PCR) rates of cataract surgery using a traditional ophthalmic surgical microscope (OSM) and a 3D heads-up visualization system (HUVS).
Setting: Single tertiary referral center.
Design: Retrospective study.
Purpose: To investigate the accuracy of the PEARL-DGS formula for intraocular lens (IOL) power calculation in post-myopic laser refractive corneal surgery eyes.
Design: Retrospective case series.
Methods: A total of 139 eyes of 139 patients (mean axial length: 27.
Purpose: To evaluate the association between dry eye disease (DED) and various psychiatric and systemic diseases in an adult Korean population aged 40 years or older.
Methods: Population-based cross-sectional data of 6,732 participants aged ≥40 years was extracted from the Korea National Health and Nutrition Examination Survey 2017-2018 (KNHANES VII). Data including DED, demographic variables, behavioral factors, psychiatric conditions, and systemic diseases was analysed to determine the prevalence and psychiatric and systemic risk factors for DED.

Femtosecond laser can provide precise and customized incision of ocular tissue with excellent accuracy and predictability. Thus, femtosecond laser-assisted cataract surgery (FLACS) can theoretically enhance the safety and efficacy of cataract surgery by providing reproducible and reliable clear corneal incision, limbal relaxing incision, anterior capsulotomy, and lens fragmentation. However, thus far, the superiority of the anatomical and visual outcomes of FLACS over those of conventional cataract surgery have been unclear.

Methods: Two hundred twenty patients with DED were randomly assigned to one of three groups: the 1% rebamipide, 2% rebamipide, or placebo (eye drops containing the same ingredients, except for the active components). Each eye drop was instilled four times daily for 12 weeks.
To compare the efficacy and ocular tolerability of a 0.08% nanoemulsion cyclosporine A (CsA) (TJO-087) once daily versus a conventional 0.05% emulsion CsA twice daily in dry eye disease.

A phase 1, randomized, double-blind, placebo-controlled, and single-ascending dose (SAD) and multiple-ascending dose (MAD) study were conducted in three dose groups (10, 50, and 100 μg/mL). The subjects randomly received rhEGF eyedrops or the placebo in a 3:1 ratio.

The effectiveness of each preparation in DES is well-known, yet the superiority of one over another has been studied little. We assessed the efficacy and tolerability of 0.

Methods: A retrospective medical chart review was performed for patients aged 15 years or younger who had been diagnosed with BKC between 2004 and 2020 at 2 tertiary hospitals in Korea. The following data were collected: demographics, medical history, ocular findings, geometric profiling of corneal lesion, medical management, and outcomes.
Purpose: This study aimed to evaluate the correlation between tear film lipid layer thickness and transepidermal water loss (TEWL) from the ocular area in patients with short tear break-up time (TBUT)-type dry eye and healthy controls.
Methods: This prospective study included 25 eyes of patients with short TBUT-type dry eye disease and 25 eyes of healthy controls.
Results: Tear film lipid layer thickness was measured using an interferometer, and TEWL from the ocular area was measured using a Tewameter TM300 with custom-made goggles.

Purpose: To investigate the difference in clinical parameters of dry eye disease (DED) according to the presence of serum anti-La antibodies and evaluate the correlations of autoantibody titers with DED parameters in patients with primary Sjögren's syndrome (pSS).
Methods: Sixty-two patients diagnosed with pSS according to the 2016 ACR-EULAR classification criteria were classified into two groups depending on the presence of anti-La antibodies: group 1 (anti-Ro positive alone, n = 31) and group 2 (both anti-Ro and anti-La positive, n = 31). DED parameters (conjunctival and corneal ocular staining score (OSS), tear film break-up time (TBUT), Schirmer I test, lipid layer thickness (LLT), meiboscore, and ocular surface disease index), serum autoantibodies (anti-Ro, anti-La, rheumatoid factor (RF), and antinuclear antibody) and focus score were assessed.
Purpose: To quantitatively analyze morphological and functional alterations of the meibomian glands in eyes with marginal entropion and their changes after surgery.
Methods: Sixty eyes of 52 patients with marginal entropion and underwent meibography and interferometer were included. One-hundred and seventeen age- and sex-matched eyes with minimal to mild meibomian gland dysfunction (MGD) were recruited as control eyes.
Background: Conjunctival myeloid sarcoma (MS) as an isolated presentation of acute myeloid leukemia (AML) relapse is rare. Here, we report a case of unilateral conjunctival MS revealed as a sign of AML relapse.
Case Presentation: A 50-year-old man with a history of AML in remission visited our clinic presenting with a left conjunctival injection persisting for 1 month.
For the long-term efficacy of dry eye disease treatment, relieving underlying inflammation is necessary. Imatinib mesylate is a novel ophthalmic formulation of imatinib mesylate, which is expected to alleviate inflammation by inhibiting the discoidin domain receptor 1 activity. This study aims to evaluate the safety and pharmacokinetics of imatinib mesylate in healthy subjects.

Methods: An in-house software for automated grading of histopathological images was developed. Histopathological images of pterygium (400 images from 40 patients) were analysed using our newly developed software.
Purpose: Dry eye disease (DED) is a multifactorial disorder of the tears and ocular surface accompanied by ocular discomfort, visual disturbance, tear film instability, and ocular surface inflammation. In the present study, we evaluated the efficacy of the tyrosine kinase inhibitor imatinib mesylate for the treatment of DED.
Methods: Experimental models of DED were generated in Sprague Dawley rats using a combination of benzalkonium chloride (BAC) with atropine sulfate and in New Zealand White rabbits using BAC.
