The association between glaucoma treatment adherence with disease progression and loss to follow-up.

Prospective cohort study from Brazil to evaluate glaucoma treatment adherence using a medication event monitoring system (MEMS) device and correlate with glaucoma progression and loss to follow-up (LTF) after one year of follow up. We included primary open glaucoma (POAG) patients treated with at least one ocular hypotensive eye drop. MEMS devices was used to monitor adherence for 60 days and evaluate the percentage of doses prescribed taken within the 60-day period.

Intrastromal corneal ring segment implantation by femtosecond laser for the correction of residual astigmatism after penetrating keratoplasty.

Purpose: To evaluate the safety and efficacy of intracorneal ring segments (ICRSs) aided by femtosecond (FS) laser for the correction of residual astigmatism after penetrating keratoplasty (PKP).

Methods: This retrospective noncomparative study comprised 14 eyes of 14 patients with high astigmatism after PKP who had ICRS implantation by femtosecond laser. The study evaluated uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refractive astigmatism, and corneal maximum curvature.

Do environmental factors influence excimer laser pulse fluence and efficacy?

Purpose: To evaluate excimer laser fluence after experimentally induced changes in room temperature and relative air humidity.

Methods: Excimer laser fluence was analyzed with a specific power meter under three different gradients of room temperature and relative air humidity as well as the reproducibility of myopic correction of -3.00 diopters in a polymethylmethacrylate plate test.

[Major indications for corneal penetrating keratoplasty at a reference service in São Paulo state (Sorocaba - SP, Brazil)].

Purpose: To identify the main indications for corneal transplantation, analyze the results and provide demographic and epidemiological profile of patients referred to the Corneal Transplantation Project.

Methods: A retrospective analysis, from June to December 2003, of patients referred to the Corneal Transplantation Project.

Results: Total of 171 patients.

Bilateral deep keratitis caused by systemic lupus erythematosus.

We report the optical and ultrasonic biomicroscopy and confocal microscopy findings in bilateral stromal keratitis (keratoendotheliitis), a rare ocular manifestation of systemic lupus erythematosus (SLE). Examination revealed deposits with polyrefringent crystals. Topical corticosteroid produced regression of the corneal edema, but there was an increase in corneal opacity.
