The IOL Master 700 and Lenstar LS900 demonstrated superior acquisition rates of biometric measurements compared with the IOL Master 500. Ocular biometry using the 3 different devices showed high agreement, although statistically significant differences were observed; however, since there was no difference in predicting the refractive outcomes, those differences are clinically negligible.

PURPOSE: To investigate the characteristics of eyes with dry eye disease (DED) whose lipid layer thickness (LLT) measured 100 nm on a LipiView II interferometer and compare the DED parameters of them to those with LLT below 100 nm. METHODS: A total of 201 eyes of 102 enrolled DED patients (mean age 56.4 ± 11.8 years) were classified into 3 groups according to their average LLT; < 60 nm as thin-LLT (n = 49), 60-99 nm as normal-LLT (n = 77), and 100 nm as thick-LLT (n = 75). LLT, meiboscore, Schir

Three percent diquafosol tetrasodium treatment could be considered as an additive or substitute treatment when artificial tear treatment is insufficient, as it improved OSS and TBUT. This study also demonstrated that diquafosol treatment is beneficial for TBUT improvement in SS, while it is beneficial for OSS improvement in non-SS dry eye patients.

There is an increasing need for an objective grading system to evaluate the severity of dry eye disease (DED). In this study, a fully automated deep learning-based system for the assessment of DED severity was developed. Corneal fluorescein staining (CFS) images of DED patients from one hospital for system development (n = 1400) and from another hospital for external validation (n = 94) were collected. Three experts graded the CFS images using NEI scale, and the median value was used as ground t

The efficacy of cyclophosphamide in the treatment of necrotising scleritis was comparable with that of other ISAs. However, the rate of discontinuation due to side effects was much higher in the CYC group.

Absolute risk of cataract was rare, with or without AD, even after 10 years of observation. However, our results suggest that pediatric patients with AD have an increased risk for cataracts requiring surgery and that disease severity may increase the risk for cataract development and cataract surgery.

PURPOSE: The purpose of this study was to determine the clinical characteristics, disease course, therapeutic outcomes, and prognostic factors for pediatric patients with blepharokeratoconjunctivitis (BKC). 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 c

Donor age may correlate with graft survival in primary PK performed with imported donor corneas. Donor age could be a considerable factor in primary PK with imported donor corneas, especially in preoperatively low-risk patients.

PURPOSE: To investigate transepidermal water loss (TEWL) from the ocular area in dry eye disease (DED) and evaluate the correlation between ocular TEWL and other DED parameters. METHODS: Transepidermal water loss from the ocular area in 56 eyes with DED and 38 healthy eyes was measured using a Tewameter TM300 that was equipped with custom made goggles (measuring temperature 24°C-26°C and relative humidity 35%-45%). The DED group was classified into two subgroups, aqueous deficient dry eye (ADDE)

Conjunctival Pyogenic Granuloma: Cases with Undetermined EtiologiesDear Editor, Conjunctival pyogenic granuloma (PG) is a benign vascular proliferation of immature capillaries that usually denotes sequelae of incomplete surgical or traumatic wound healing [1,2].It is most commonly seen at a traumatic wound site or near a suture line after surgery and other insults [3].Herein, we report three cases of conjunctival PG with unknown etiology in children and a young adult.Case 1.An 8-year-old boy pre

BACKGROUND: Posterior polymorphous corneal dystrophy (PPCD) is typically considered bilateral and asymptomatic. However, few case reports on patients with unilateral PPCD with asymmetric refractive error have mentioned anisometropic amblyopia development. In support of this, we report 3 cases of unilateral PPCD that presented as anisometropic astigmatism. Visual prognosis related to amblyopia development is discussed. CASE PRESENTATION: All 3 patients had a band lesion in the affected eye and a

If a patient with a history of CL wear for an extended period of time presents with decreased visual acuity, practitioners should perform detailed examinations with suspicion of CL-LSCD, including fluorescein staining. CL-LSCD is usually reversible and close follow-up with conservative treatment is recommended as the initial treatment option.
