Correlations between different tonometries and ocular biometric parameters in patients with primary congenital glaucoma.

Purpose: To identify the correlation between the difference of intraocular pressure measurements (IOP) obtained using the Goldmann applanation tonometer (GAT) and three others tonometers (Handheld applanation tonometer - HAT, Dynamic contour tonometer - DCT and Tono-Pen®) with biometric characteristics (corneal diameter, pachymetry, keratometry and axial length) in patients with congenital glaucoma.

Methods: A cross-sectional study was performed on 46 eyes from 46 patients with congenital glaucoma. IOP measurements were obtained in all patients using GAT, HAT, DCT and Tono-Pen®.

[Central corneal thickness and its correlations with other ocular biometric data in patients with congenital glaucoma].

Purpose: To study the distribution of the central corneal thickness and its correlations with other biometric data in patients with congenital glaucoma.

Methods: Patients had been divided into two groups: group "A", composed of patients with congenital glaucoma, being subdivided in two sub-groups: with Haab striae (A1) and without Haab striae (A2), and group"B" that represented the controls.

Results: The group A presented corneal diameter between 11 and 15.

Visual impairment secondary to congenital glaucoma in children: visual responses, optical correction and use of low vision AIDS.

Introduction: Congenital glaucoma is frequently associated with visual impairment due to optic nerve damage, corneal opacities, cataracts and amblyopia. Poor vision in childhood is related to global developmental problems, and referral to vision habilitation/rehabilitation services should be without delay to promote efficient management of the impaired vision.

Objective: To analyze data concerning visual response, the use of optical correction and prescribed low vision aids in a population of children with congenital glaucoma.

Ultrasonographic findings in patients examined in cataract detection-and-treatment campaigns: a retrospective study.

Introduction: A cataract is defined as an opacity of any portion of the lens, regardless of visual acuity. In some advanced cases of cataracts, in which good fundus visualization is not possible, an ultrasound examination provides better assessment of the posterior segment of the globe.

Objectives: This study aims to evaluate the ultrasonographic records of patients with advanced cataracts who were examined during cataract campaigns.

[Automated perimetry in patients with primary congenital glaucoma].

Purpose: To identify and characterize defects using the automated perimetry test in patients with primary congenital glaucoma.

Methods: Automated visual fields and charts of 81 eyes (48 patients) with congenital glaucoma were retrospectively analyzed, 15 being normal eyes (group N) and 66 eyes with primary congenital glaucoma (group G). Eyes of group G were grouped in eyes without perimetric changes and with early defects, characterized by MD > -6 dB (group G I= 41 eyes), and eyes with mild/advanced perimetric defects characterized by MD < or = -6 dB (group G II= 25 eyes).

Corneal thickness in congenital glaucoma.

Purpose: To compare central corneal thickness between eyes with congenital glaucoma and normal controls and to correlate this parameter with corneal diameter and axial length.

Methods: Eyes of consecutive children with congenital glaucoma with previous glaucoma surgery and eyes of children with inadequacy of lacrimal drainage system with age less than 3 years old were examined under inhalatory general anesthesia. Complete ophthalmologic examination, central corneal thickness, axial length, and corneal diameter measurements were performed.
