[Application of corrective formula for intraocular pressure changes in patients that underwent LASIK].

Purpose: To compare the intraocular pressure (IOP) pre and post LASIK, correlating it to changes in central corneal thickness (CCT) and average simulated keratometry (K), as well as verifying the results of a corrective formula previously proposed.

Methods: Longitudinal prospective study conducted in outpatients that underwent to LASIK. Patients underwent complete ophthalmic examination, previously and 2 months after the surgery.

[The lacrimo-auriculo-dento-digital syndrome (LADD): case report and literature review].

Levy-Hollister or lacrimo-auriculo-dento-digital (LADD) syndrome is a rare entity with autossomic dominant inheritance occuring as an isolated form or affecting many family generations. Diagnosis is based on the identification of the lacrimal drainage system abnormalities with reduction or absence of tear production and bone, teeth, salivar glands and outer ear abnormalities. A 13 year-old male patient has been followed at the Hospital Servidor Público Estadual in São Paulo due to dry eye since his first year of life.

Impression cytology features of conjunctival nevi reported as more noticeable.

Purpose: To report the impression cytology features of conjunctival nevi reported as more noticeable.

Methods: 35 patients who reported that a conjunctival lesion had become more noticeable after color or size change were enrolled. On slit-lamp examination, a clinical diagnosis of nevus was made and lesions underwent impression cytology using acetate cellulose strips and a combined staining with PAS, H&E and Papanicolaou.

[Corneal transplantation in keratoconus: evaluation of results and complications obtained by skillful and surgeons in training].

Purpose: Refractive and visual analysis in corneal transplantations performed for keratoconus by two groups of surgeons.

Methods: Seventy eyes of seventy patients, which had been submitted to penetrating keratoplasty (PK) for keratoconus, were examined and their charts were reviewed retrospectively for long-term results after all sutures had been removed. The patients were divided into two groups, Group I had surgery performed by skillful surgeons and Group II by surgeons in training.

[Diagnosis of Acanthamoeba corneal infection by impression cytology: case report].

To describe three cases of corneal infection due to Acanthamoeba sp in which was possible to detect Acanthamoeba sp cysts by the corneal impression cytology technique. Three patients referred to the External Eye Disease Laboratory in 2004 with superficial corneal alterations were submitted to corneal specimen collection by impression cytology filter paper to investigate the presence of Acanthamoeba sp cysts. Two impression cytology samples were obtained from each patient and were stained by PAS, hematoxylin and Papanicolaou.

Diagnosis of epithelial ingrowth after penetrating keratoplasty with confocal microscopy.

Purpose: To report confocal microscopy use in the clinical diagnosis of epithelial ingrowth after penetrating keratoplasty (PKP).

Methods: A 36-year-old female patient with keratoconus developed a well-delimited posterior hazy membrane covering the inferior two thirds of the cornea 3 months after an uneventful PKP. A posterior corneal line was present resembling an endothelial graft rejection line, but with no keratic precipitates or corneal edema.

Amniotic membrane transplantation for partial and total limbal stem cell deficiency secondary to chemical burn.

Purpose: To evaluate the surgical outcome of preserved amniotic membrane transplantation (AMT) for ocular surface reconstruction in chemical burn with limbal stem cell deficiency.

Design: Prospective, noncomparative, interventional case series.

Participants: Twenty eyes of 20 consecutive patients with limbal stem cell deficiency secondary to ocular chemical injury.
