PURPOSE To quantify the degree of metamorphopsia in patients with idiopathic epiretinal membranes (ERMs), by use of a new metamorphopsia chart (M-CHARTS) developed by the authors. METHODS These M-CHARTS had 19 dotted lines with dot intervals of between 0.2 degrees (fine) and 2.0 degrees (coarse) visual angles. As the dot intervals were changed from fine(More)
PURPOSE In cases of macular hole, metamorphopsia is one of the most important symptoms, along with decreased visual acuity and a central scotoma. We investigated the relationship between the degree of metamorphopsia and the morphological appearance of macular holes. METHODS Using M-CHARTS developed by ourselves, we quantified the metamorphopsia scores in(More)
after treatment even though a high dose of ACV was administered. Second, 4 weeks after treatment, VZV-DNA was negative in PCR even though cells and flare could be observed in the anterior chamber of the diseased eye. PCR has been performed successfully to detect viral DNA in ocular samples. Nagae et al. reported that in 12 eyes of 9 patients with viral(More)
PURPOSE Using M-CHARTS (Inami Co., Tokyo, Japan), which were developed by the authors to measure metamorphopsia, and image-analysis software, which was developed to quantify retinal contraction, the authors investigated the relationship between the degree of retinal contraction and the degree of metamorphopsia in eyes with idiopathic epiretinal membrane(More)
PURPOSE We evaluated the clinical usefulness of flicker perimetry in glaucoma and glaucoma suspect patients using the new Octopus 311 automated perimeter. METHODS A total of 52 eyes of 52 glaucoma patients, 26 eyes of 26 glaucoma suspect patients and 61 eyes of 61 normal subjects were examined using standard automated perimetry (SAP), flicker perimetry(More)
PURPOSE To assess the correlations between a patient's subjective perception of metamorphopsia and the clinical measurements of metamorphopsia by M-CHARTS and PreView PHP (PHP). METHODS The authors designed a 10-item questionnaire focusing on the symptoms of metamorphopsia and verified its validity with a Rasch analysis. M-CHARTS measured the minimum(More)
PURPOSE To compare the detectability between glaucomatous visual field changes using standard automated perimetry (SAP), frequency doubling technology (FDT), short-wavelength automated perimetry (SWAP), and flicker perimetry and structural changes using optical coherence tomography (OCT). PARTICIPANTS Fifty-nine eyes of fifty-nine patients with open-angle(More)
BACKGROUND To quantify changes in metamorphopsia and retinal contraction in eyes with idiopathic epiretinal membrane (ERM) before and after a spontaneous separation of ERM. METHODS Among 92 eyes of 92 patients with idiopathic ERM who were followed up at our hospital, 5 eyes of 5 patients had experienced a spontaneous separation of ERM during the follow-up(More)
PURPOSE To report the efficacy of phototherapeutic keratectomy (PTK) and deep lamellar keratoplasty (DLKP) in the treatment of Acanthamoeba keratitis. METHODS Two patients with delayed diagnosis of Acanthamoeba keratitis failed to respond to multiple systemic and topic antiamoebic agents supplemented by twice-weekly corneal scraping. Three weeks into such(More)
