PURPOSE To investigate the distribution of axial length, anterior chamber depth, lens thickness, vitreous chamber depth, and central corneal thickness in children at different age groups. METHODS We studied 364 eyes in 182 children with ages between 1 and 12 years. Axial length, anterior chamber depth, lens thickness, and vitreous chamber depth were measured by ultrasound biometry. Central co...

A total of 80 patients with senile cataract had the anterior eye chamber depth measured optically by means of Haag-Streit's attachment II. The distance to the pupillary border was 2.59 +/- 0.05 mm (mean +/- SEM) preoperatively. It increased gradually after cataract extraction to 3.33 +/- 0.04 mm, measured 4 months after the operation. The increase of depth was the greatest in patients with a fl...

The depth of the anterior chamber was measured in 34 eyes with pseudoexfoliation but without glaucoma and in 334 normal controls. No significant difference was found.

PURPOSE To compare anterior segment and ocular biometric parameters in unaffectedfellow eyes of patients with a previous attack of acute angle closure (AAC), primary angle closure suspect (PACS) eyes, and normal eyes; and to identify eyes at high risk of AAC among primary angle closure suspects. METHODS In this case-control study, 16 unaffected fellow eyes of patients with aprevious attack of...

A technique is proposed which allows assessment of the anterior chamber depth with a standard table slit-lamp without any extra attachments. A final approximation is made which suggests that a 1 degree change in the angle between the observation and illumination systems of the slit lamp when the end point is reached indicates a change in anterior chamber depth of 0.1 mm.

PURPOSE To characterize short-term changes induced by pars plana vitrectomy on anterior segment depth and lens thickness by means of high-frequency ultrasound biomicroscopy. METHODS We undertook a prospective case series study on consecutive patients referred for pars plana vitrectomy as the sole procedure in our institution between 2005 and 2007. Twenty-eight eyes of 28 patients undergoing p...

Aim. To assess the effects of mydriatics commonly used in clinical practice on choroidal thickness and anterior chamber change. Methods. This was a prospective, randomized, controlled, double-blinded study including a single eye of the participants. The subjects were assigned into 4 groups to receive tropicamide 1%, phenylephrine 2.5%, cyclopentolate 1%, and artificial tears. At the baseline, a...
