Corneal hysteresis measured with the Ocular Response Analyzer in normal and glaucomatous eyes.

Purpose: To identify differences in corneal hysteresis (CH) and central corneal thickness (CCT) between healthy and glaucomatous patients.

Methods: Retrospective observational study. One hundred and thirty-three eyes of 75 healthy and 58 glaucomatous patients were included.

[Optic nerve head analysis using the confocal scanning laser ophthalmoscope (CSLO) of big cups versus normal cups].

Purpose: To comparatively evaluate the optic nerve head (ONH) using the confocal scanning laser ophthalmoscope (CSLO) in normal eye subjects (NE) versus big cup (BC) patients.

Materials And Methods: A total of 83 NEs (43 subjects) and 44 BC eyes (22 patients) were evaluated in this prospective study. The ONH was imaged using the CSLO (HRT-II; Heidelberg Engineering, Heidelberg, Germany).

Effect of pterygium surgery on corneal topography.

Purpose: To evaluate the effect of successful pterygium surgery on corneal topography.

Methods: Computerized corneal topography was performed on 20 eyes with pterygium before and 3 months after successful excision and limbo-conjunctival autograft surgery. Corneal shape, corneal spherical power, simulated keratometric astigmatism, surface regularity index (SRI), and surface asymmetry index (SAI) were assessed before and after surgery.
