Tonography assessment using quantitative and qualitative analysis of the aqueous humor outflow mechanism.

Purpose: To perform qualitative evaluation of the aqueous humor (AH) outflow mechanism in glaucoma and nonglaucoma patients by means of tonography assessment and mathematical analysis.

Methods: Sixty-two primary open angle and 58 pseudoexfoliation glaucoma patients were recruited in a non-interventional, observational study between 2004 and 2007. Qualitative and quantitative outflow assessment was acquired by means of a digital tonographer and mathematical analysis.

Laser in situ keratomileusis flap-thickness predictability with a pendular microkeratome.

Purpose: To assess flap-thickness predictability with a pendular microkeratome (130 μm head).

Setting: Eye Institute of Thrace, Democritus University of Thrace, Alexandroupolis, Greece.

Design: Clinical trials.

The digital aqueous humor outflow meter: an alternative tool for screening of the human eye outflow facility.

Purpose: To develop, characterize, and validate a prototype digital aqueous humor outflow tonographer (DAHOM).

Material And Methods: The DAHOM was developed, characterized, and validated in three phases. Phase 1 involved construction of the sensor.

Evaluation of the retinal nerve fiber layer measurements, after photorefractive keratectomy and laser in situ keratomileusis, using scanning laser polarimetry (GDX VCC).

Background: To evaluate the impact of photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK), on retinal nerve fiber layer (RNFL) measurements, by means of scanning laser polarimetry (SLP) GDx VCC (with variable corneal compensation).

Methods: Two groups of 119 myopic patients each were treated by PRK and LASIK respectively; one eye of each patient was randomly selected for the study. RNFL measurements (around the entire calculation circle) was performed in all eyes 1 day before and 1, 3, 6 and 12 months after treatment by using SLP GDx VCC.
