[Simulation of toric intraocular lens results: the effect of repeatability and increments of automated keratometry].

Objective: To study the repeatability and scale increments of automated keratometry and their influence on the use of the toric intraocular lens (IOL) and on astigmatism correction.

Method: The study enrolled 131 eyes of 82 patients. Preoperative corneal astigmatism was measured in the different (0.

Unilateral Variant of Late-Onset Lattice Corneal Dystrophy With the Pro501Thr Mutation in the TGFBI Gene Without Deposits in the Unaffected Cornea Using Confocal Microscopy.

Purpose: To report a case of a unilateral variant of late-onset lattice corneal dystrophy (LCD) with the Pro501Thr mutation in the TGFBI gene with unilaterality confirmed by confocal microscopy.

Methods: Case report. A 58-year-old man presented with visual impairment in his left eye of 20-year duration.

Prevalence and features of keratitis with quantitative polymerase chain reaction positive for cytomegalovirus.

Purpose: To assess corneal scrapings and aqueous humor samples analyzed by polymerase chain reaction (PCR) that were positive for cytomegalovirus (CMV) in patients with keratitis of unknown origin and to investigate their clinical manifestations.

Design: Retrospective, interventional case series.

Participants: Seventy-eight patients with epithelial (n=37), stromal (n=12), or endothelial keratitis (n=29) of unknown origin examined at the Osaka University Medical Hospital.

Two cases of acanthamoeba keratitis diagnosed only by real-time polymerase chain reaction.

Purpose: To report 2 cases of Acanthamoeba keratitis whose causative pathogen was detected only by real-time polymerase chain reaction (PCR).

Methods: Histological examinations of corneal scrapings were stained with Fungiflora Y. Corneal scrapings were also cultured on nonnutrient agar.

The blood group P1 synthase gene is identical to the Gb3/CD77 synthase gene. A clue to the solution of the P1/P2/p puzzle.

Blood group P1/P2 is a glycolipid antigen system for which the genetic mechanism has not yet been clarified. We analyzed the potential of the cloned Gb3/CD77 synthase to synthesize P1 antigen, because Gb3/CD77 and P1 share a common structure, Galalpha1,4Galbeta1,4Glc (NAc)-. L cell transfectants with Gb3/CD77 synthase cDNA expressed marginal levels of P1 on the cell surface but contained high levels of P1 in the cytoplasm.
