To investigate the postnatal risk factors of retinopathy of prematurity (ROP), we analysed demographic and clinical data abstracted from the medical records of 425 premature babies who were examined for ROP between January 1994 and December 1998 at Asan Medical Centre, Seoul, Korea. ROP developed in 20.7% of the cases studied. A gestational age (GA) of < or = 28 weeks and birthweight (BW) of < or = 1000 g were the most significant risk factors. Ventilator care for > or = 48 h, apnoea, and use of

PURPOSE: One aim of corneal refractive surgery is to correct defocus and astigmatism. In the process of correcting lower order aberrations, higher order ocular aberrations increase. To evaluate the effectiveness of wavefront-guided laser in situ keratomileusis (LASIK) in reducing the increase of higher order aberration, we compared aberrational change after LASIK with conventional and wavefront-guided customized ablation. METHODS: Our study included 48 eyes of 24 patients. We performed conventio

MMC is a potent inhibitor of corneal haze induced by PRK. MMC reduced the number of keratocytes and fibroblasts after PRK and UV-B irradiation. Although MMC would improve the clinical results of PRK, it has significant toxicity on corneal keratocytes, which did not disappear until 3 months after PRK.

PURPOSE: To determine the effects of clinical variables, including age, sex, history of refractive or cataract surgery, contact lens use, and ocular surface and meibomian gland parameters on the lipid layer thickness (LLT) in normal subjects and patients with dry eye syndrome (DES). METHODS: A total of 64 normal subjects and 326 patients with DES were enrolled, and they underwent measurements of LLT with a LipiView interferometer and tear meniscus height using optical coherence tomography, tear

Mitomycin C induced apoptosis, not necrosis, in cultured corneal keratocytes through the caspase pathway-specifically, caspase-8 and -9-related to the mitochondrial pathway.

PURPOSE: Vascular endothelial growth factor (VEGF) is essential for neovascularization, but the use of anti-VEGF therapies to inhibit neovascularization may influence epithelial wound healing. Here, the effects of bevacizumab on corneal epithelial wound healing time in rabbit models, cell proliferation, and expression of integrins in human corneal epithelial and fibroblast cells were evaluated. METHODS: To compare epithelial wound healing times, epithelial defect sizes were measured after applic

Subconjunctival bevacizumab administration decreased suture-induced corneal neovascularization in rabbits.

PURPOSE: To compare the accelerated corneal cross-linking (CXL) protocol and the conventional Dresden protocol in patients with keratoconus in terms of visual acuity, keratometric values, and topographic parameters. METHODS: Twenty-eight eyes of 25 patients with primary keratoconus were divided into 2 groups; 15 eyes in group 1 received CXL under the standard Dresden protocol (3 mW/cm for 30 min, dose 5.4 J/cm) and 13 eyes in group 2 were treated with the accelerated protocol (30 mW/cm for 3 min

PURPOSE: To evaluate perioperative dry eye (DE) syndrome and meibomian gland dysfunction (MGD) parameters associated with persistent DE symptoms after cataract surgery. METHODS: We enrolled patients who underwent uncomplicated cataract surgery without previous ocular comorbidities and previous use of ophthalmic treatment except for artificial tears at a single tertiary hospital. Lipid layer thickness, meibomian gland (MG) dropout, tear breakup time, Oxford staining score, lid margin abnormality,
