Purpose: This study aimed to analyze variations in intraoperative corneal thickness during corneal cross-linking in patients with keratoconus and to investigate its possible correlation with presurgical maximal keratometry (Kmax) and pachymetry.
Methods: This was a prospective case series. We used a method similar to the Dresden protocol, with the application of hydroxypropyl methylcellulose 0.
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.

Design: Retrospective, interventional consecutive case series.
Methods: Medical records of every child 7 years of age or younger who underwent primary penetrating keratoplasty at Department of Ophthalmology, Federal University of São Paulo were reviewed.
Purpose: To report a series of cases of Acanthamoeba keratitis (AK) in scleral lens wearers with keratoconus to determine whether this type of contact lens presents a greater risk for development of infection.
Methods: This study reports three patients who wore scleral contact lenses to correct keratoconus and developed AK. The diagnoses of AK were established based on cultures of the cornea, scleral contact lenses, and contact lens paraphernalia.
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.
Purpose: To evaluate the quality of the corneas processed by Sorocaba Eye Bank (BOS) - SP and transplanted out of the Ophthalmology Hospital of Sorocaba (HOS), as well as the corneas that had re-entered in the BOS, being transplanted or not in the HOS, during the year of 2007.
Methods: Ophthalmologists that transplanted corneas processed by BOS outside of the Ophthalmology Hospital of Sorocaba were contacted, as well as those who had used re-entried corneas, to collect the following information: period from eye enucleation until transplant, transparency of the donated tissue, time of transplant and primary failure.
Results: During the year of 2007, Sorocaba Eye Bank distributed three hundred and ninety-two corneas for outside HOS.
Purpose: To study the therapeutic potential of amniotic membrane transplantation in cases of severe acute chemical ocular burn and Stevens-Johnson syndrome.
Methods: We retrospectively reviewed the records of eight patients, with a total of ten eyes, submitted to amniotic membrane transplantation for treatment of ocular chemical burns and Stevens-Johnson syndrome in the acute phase between January 1999 and May 2008 in the Ophthalmology Department of UNIFESP. Data relating to sex, age, degree of chemical burns, etiology, affected eye, ophthalmological findings, extension of amniotic membrane, surgeries, additional time between the injury and surgery in days, visual acuity before and after surgery, epithelial defect healing (days), complications and time of follow-up in months were collected.
Purpose: To compare the measurement of contrast sensitivity at a distance in patients submitted to penetrating keratoplasty versus patients submitted to deep anterior lamellar keratoplasty for keratoconus treatment.
Methods: Contrast sensitivity of fourteen subjects submitted to penetrating keratoplasty and fourteen subjects submitted to deep anterior lamellar keratoplasty have been analyzed through the Functional Acuity Contrast Test (F.A.
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.
Purpose: To describe the microbiologic aspects of infectious keratitis in children (0-18 years old) examined at the Department of Ophthalmology of the National University of Asunción-Paraguay, during a 14-year period (1988-2002).
Methods: The authors retrospectively studied 146 children, under 18 years old, with infectious keratitis at the Department of Ophthalmology of the National University of Asunción-Paraguay, from 1988 to 2002.
Results: The cultures were positive in 113 patients (77%) with 70% of bacterial and 30% of fungal etiology.
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.
Unlabelled: To report an unusual case of fungus keratitis due to Fonsecaea pedrosoi that developed after corneal trauma.
Case Report: A 18-year-old male presented with a corneal ulcer in the right eye, 28 days after a trauma with glass fragments. Corneal scrapings were collected for smears and culture.
Purpose: To analyze the frequency and the etiology of mycotic infectious eye diseases diagnosed by culture at the Ocular Diseases Laboratory of the Federal University of São Paulo (LOFT-UNIFESP), São Paulo, SP, Brazil, and the factors associated with fungal keratitis.
Methods: We retrospectively analyzed the 14,391 laboratory requests regarding infectious eye diseases between 1975 and May 2003. For the fungal culture proven examinations we observed the morphologic type of the isolated fungus, the gender and age of the patient, the site of ocular involvement, the year of identification, and the factors associated with keratitis cases, according to the identified etiologic agent.
Purpose: To report risk factors, clinical course, and outcome in patients with infectious keratitis following implantation of intracorneal ring segments (ICRS).
Methods: The records of 8 patients with culture-proven infectious keratitis after ICRS (Ferrara or Intacs) implantation were retrospectively reviewed. Age, gender, corneal findings, ocular abnormalities, the condition that led to ICRS implantation, immediate prior use of a contact lens, elapsed time between implantation and the onset of symptoms, previous medications, and systemic disorders were noted.
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.
