PURPOSE To review the trends, risk factors, causative organisms, treatment, and outcomes of fungal keratitis at the authors' institution. METHODS A retrospective review of the records of consecutive patients diagnosed with fungal keratitis at the authors' institution from January 1999 to June 2006. RESULTS Eighty-four patients were diagnosed with fungal(More)
PURPOSE Connective tissue growth factor (CTGF) appears to play a significant role in mediating fibrosis in several tissues. To gain further understanding of the role of CTGF in the scar formation that occurs after glaucoma filtering surgery (GFS), experiments were performed in a rabbit model. METHODS . Three experiments were performed: (1) CTGF and(More)
PURPOSE To study the intraocular pressure (IOP)-lowering effect of adding a third or a fourth antiglaucoma medication to preexisting antiglaucoma medical therapy, for a follow-up period of one year. PATIENTS AND METHODS The authors performed a retrospective, nonrandomized, noncomparative, interventional study including all patients seen by a single(More)
PURPOSE To review studies of fungal keratitis related to contact lenses and determine whether the recent insurgence is a new phenomenon or an exacerbation of an ongoing trend. METHODS A review of the recent literature on contact lens-related fungal ulcers and a comparison to older studies. RESULTS The incidence of fungal keratitis associated with(More)
PURPOSE To report a case of ectasia occurring > 4 years following LASIK with no risk factors and a residual stromal bed > 300 microm. METHODS A 33-year-old woman presented 4 years after LASIK with mild blurring in the left eye. Uncorrected visual acuity (UCVA) had been 20/20 in both eyes previously. RESULTS Uncorrected visual acuity was 20/20 and 20/40(More)

An optical fiber anemometer that uses laser-induced phosphorescence to measure particle time of flight in dense gas-solid suspensions is described. The anemometer is tested using a spinning disk coated with a phosphor having a persistent afterglow. The diagnostic technique is illustrated by measuring the velocity of free-falling particles coated with the(More)
