Intraoperative optical coherence tomography (RESCAN 700) for detecting iris incarceration and iridocorneal adhesion during keratoplasty.

There is no report focusing on the visualization of the iris incarceration or the iridocorneal adhesion during keratoplasty by use of microscope-integrated intraoperative optical coherence tomography (MIOCT). The purpose of this study is to report the usefulness of MIOCT for detecting iris incarceration and iridocorneal adhesions during penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK). MIOCT system was applied both in a patient who underwent PK for corneal leukoma and in a patient who underwent DALK for keratoconus.

Development of a new fully automated kinetic algorithm (program k) for detection of glaucomatous visual field loss.

Purpose: In Program K, a new automated kinetic algorithm that we developed, the frequency distributions of the number of patients' response points were obtained for external angles to distinguish normal and abnormal isopters. We also assessed the agreement between the results of Program K and Goldmann manual kinetic perimetry (MKP).

Methods: Program K detected abnormalities in isopters by using the external angles of patients' response points.

CLOCK CHART(®): a novel multi-stimulus self-check visual field screener.

Purpose: CLOCK CHART(®) is a multi-stimulus-type self-check visual field screening sheet developed by our group. The test chart is rotated during the examination, and the visual field abnormalities are pointed out by the patients themselves. In this study, we evaluated the clinical usefulness of this chart in patients with glaucoma.
