Corneal endothelial density and morphology in long-term soft contact lens users in Japan: a retrospective cross-sectional study of 17,732 eyes.
Cutan Ocul Toxicol
December 2024
Department of Ophthalmology, Miyata Eye Hospital, Miyazaki, Japan.
Article Synopsis
- A study was conducted to investigate the long-term effects of soft contact lens (SCL) usage on the corneas of Asian individuals, focusing on corneal endothelial density (ECD) and cell shape.
- The research analyzed data from nearly 9,000 patients who used SCLs for over a year, assessing various factors including age, sex, and duration of lens use.
- Findings showed that as the duration of SCL use increased, both ECD and the rate of hexagonal cells decreased, while the variation in cell size increased, highlighting the importance of regular eye check-ups for long-term SCL wearers.
Blepharokeratoconjunctivitis Presumably Caused by , a Beetle: A Case Report.

Department of Ophthalmology, Miyata Eye Hospital, Miyazaki, Japan.
Toxicity of species to eyes has scarcely been reported. This report presents a case of chemical blepharokeratoconjunctivitis with delayed re-epithelialization caused by in a patient with dry eye after laser-assisted in situ keratomileusis (LASIK). A 47-year-old woman who had undergone LASIK for myopia 10 years prior experienced visual disturbance and pain in her left eye after being hit by a insect in her eye 1 day prior to evaluation.

Article Synopsis
- A study compared the effectiveness and comfort of two eye drop combinations (BTFC and DTFC) for patients with glaucoma or ocular hypertension who were already on prostaglandin analogues.
- The trial involved 110 participants who switched between the two treatments over a period of 16 weeks, measuring intraocular pressure (IOP) reduction, side effects, and patient preferences.
- Results showed that both treatments were similarly effective in lowering IOP, but patients reported less discomfort and preferred BTFC, suggesting it may be a better option for those sensitive to eye irritation.
Corneal Edema with Anterior Uveitis after Exposure to the Sap of : A Case Report.
Case Rep Ophthalmol
August 2021
Department of Ophthalmology, Miyata Eye Hospital, Miyazaki, Japan.
Although a few cases of dermatitis or keratitis caused by exposure to the sap of have been reported, we present a rare case of transient corneal endothelial dysfunction following exposure to the sap, resulting in corneal edema. A woman in her 70s complained of reduced vision, redness, and teariness in her left eye 2 days after exposure to the sap of at home. Upon examination, hyperemia, serious corneal edema, and anterior uveitis with hypopyon were observed in her left eye, without corneal epithelial defects or keratic precipitates.

Purpose: To assess the long-term influence of surface light scattering and glistenings of hydrophobic acrylic (Acrysof), silicone, and poly(methyl methacrylate) (PMMA) intraocular lenses (IOLs) on visual function.
Setting: Eleven surgical sites, Japan.
Design: Retrospective case series.
Purpose: To determine steep increase of corneal irregularity induced by advancement of pterygium.
Methods: A total of 456 eyes from 456 consecutive patients with primary pterygia were examined for corneal topography and advancement of pterygium with respect to the corneal diameter. Corneal irregularity induced by the pterygium advancement was evaluated by Fourier harmonic analyses of the topographic data that were modified for a series of analysis diameters from 1 mm to 6 mm.
