Retinitis pigmentosa with concomitant essential iris atrophy and glaucoma - case report.

Purpose: To report a case of a young patient with retinitis pigmentosa (RP), essential iris atrophy, and glaucoma.

Case Report: This report presents a case of a 22-year-old female patient with unilateral glaucoma, increased intraocular pressure, increased cup-disc ratio, iris atrophy, peripheral anterior synechiae, and bilateral RP.

Discussion: The patient presented glaucoma due to the iridocorneal endothelial syndrome, despite low age.

[Correlation between central corneal thickness and axial length in patients with glaucoma and normal eyes].

Purpose: To evaluate and to correlate the central corneal thickness with the ocular axial length in patients with primary open-angle glaucoma, primary angle-closure glaucoma and individuals with normal eyes.

Methods: The sample was composed of 94 patients' eyes, divided into three groups constituted of 33 eyes of 33 primary open-angle glaucoma patients, 30 eyes of 30 primary angle-closure glaucoma patients and 31 normal eyes of 31 individuals. The central corneal thickness and the axial length were measured by ultrasonic pachymeter and biometry by A-scan ultrasound, respectively.

Evaluation of the factors associated with the reversal of the disc cupping after surgical treatment of childhood glaucoma.

Purpose: To evaluate the change in optic disc cupping after surgical procedure for congenital glaucoma and assess the factors that may intervene on this process.

Methods: Prospective study involving 45 eyes of 36 patients with childhood glaucoma, who underwent surgical treatment at the Hospital Municipal da Piedade, Rio de Janeiro, Brazil, between January 1998 and December 2005. The study included patients <5 years old with intraocular pressure (IOP) <19 mm Hg for at least 6 months after surgery.

[Comparative study between diurnal intraocular pressure curve and the association of ambulatory intraocular pressure curve with the water-drinking test in open angle glaucoma, normal tension glaucoma and normal eyes].

Purpose: To evaluate and correlate the peaks and the fluctuation of intraocular pressure seen in the association of the ambulatory intraocular pressure curve with the water-drinking test versus the peaks and the fluctuation seen in the daily intraocular pressure curve.

Methods: The sample was as follows: 77 eyes belonging to 77 patients who were divided into three groups composed of 31 eyes belonging to 31 patients with primary open-angle glaucoma, 26 eyes belonging to 26 patients with normal tension glaucoma and 20 normal eyes belonging to 20 individuals.

Results: A significant correlation could be observed between the pressure peaks collected from the daily intraocular pressure curve and the pressure peaks seen in the ambulatory intraocular pressure curve, on the water-drinking test, as well as in the association of the ambulatory intraocular pressure curve with the water-drinking test.

[Relationship between corneal thickness and severity of visual field loss in primary open-angle glaucoma].

Purpose: To assess whether central corneal thickness is related to glaucomatous visual field loss severity among patients with office-controlled intraocular pressure in the normal range.

Methods: This transversal study included 85 eyes of 85 patients with treated primary open-angle glaucoma and documented intraocular pressure below 19 mmHg. The patients were divided into three groups according to Anderson criteria of field abnormality.
