Reliability of Refraction, Keratometry, and Intraocular Pressure Measurements with an Automated All-in-one Device.

Significance: This study explores the reliability of TonoRef II (Nidek, Tokyo, Japan), which represents a simple tool to obtain rapid refractometry and tonometry measurements. The present device demonstrates very high repeatability of refraction and intraocular pressure (IOP) readings as compared with subjective measurements and a higher concordance of IOP readings to Goldmann application tonometry (GAT).

Purpose: This study aimed to evaluate the repeatability of measurements acquired with the Autorefractometer/Keratometer/Tonometer TonoRef II and assess their agreement to subjective measurements and readings of other established devices.

Influence of Intraocular Lens Asphericity and Blue Light Filtering on Visual Outcome, Contrast Sensitivity, and Aberrometry after Uneventful Cataract Extraction.

Purpose: To evaluate the effect of asphericity and blue light filter (BLF) of three different intraocular lenses (IOLs) on the visual performance, second- and third-order aberrations (defocus, coma, trefoil), and contrast sensitivity after uneventful cataract surgery.

Methods: One hundred and twenty eyes of 60 patients with clinically significant cataract were randomly assigned to receive one of the three IOL types: Bioline Yellow Accurate (aspheric, with BLF, i-medical, Germany), BioAcryl 60125 (spherical, without BLF, Biotech, France), and H65C/N (aspheric, without BLF, PhysIOL, Belgium). Each IOL was implanted in 40 eyes.

Selective laser trabeculoplasty (SLT): 1-year results in early and advanced open angle glaucoma.

The purpose of this study was to examine the efficacy of selective laser trabeculoplasty (SLT) in eyes with early and more advanced stages of open angle glaucoma within 1 year of follow-up. Retrospective chart review in a consecutive series of patients treated by SLT to reduce intraocular pressure (IOP) or decrease number of topical medications in cases of discomfort and allergy. The cup-to-disc ratio of the optic nerve and the GSS 2 (glaucoma staging system 2) was used to differentiate between early (group 1) and more advanced (group 2) stages of glaucoma.

Association of ocular hypotensive medication types with dynamic contour tonometry and Goldmann applanation tonometry measurements in a glaucoma and ocular hypertensive population.

Purpose: The aim of this study was to evaluate the association between different intraocular pressure (IOP)-lowering medications and IOP measurements by dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) in a glaucoma and ocular hypertensive population.

Methods: In a prospective, observational case series study, 410 eyes from 410 consecutive patients with open-angle glaucoma (OAG) or ocular hypertension (OHT), were enrolled. All eyes included in the study received unaltered ocular hypotensive medication for at least 6 months before IOP measurement.

Decreased ocular pulse amplitude associated with functional and structural damage in open-angle glaucoma.

Purpose: To assess the relationship of ocular pulse amplitude (OPA), as measured by dynamic contour tonometry (DCT), with structural and functional damage in patients with open-angle glaucoma (OAG).

Methods: In this cross-sectional, observational study, 242 eyes of 139 patients with OAG underwent Goldmann applanation tonometry (GAT), DCT, central corneal thickness (CCT) measurement, visual fields examination (Octopus, Haag Streit), and complete ophthalmologic examination. Linear regression analysis was used to analyze the effect of OPA, DCT, GAT, and CCT to the mean defect (MD) of the visual fields and to the vertical cup to disc ratio (CDR).

Central corneal thickness during treatment with travoprost 0.004% in glaucoma patients.

Purpose: Experimental studies demonstrated an alteration of corneal collagen structure by prostaglandin analogues. The possible effect of the prostaglandin F(2alpha) analogue travoprost 0.004% on the central corneal thickness (CCT) in newly diagnosed glaucoma patients was evaluated.

Improved reproducibility of retinal nerve fiber layer thickness measurements with the repeat-scan protocol using the Stratus OCT in normal and glaucomatous eyes.

Background: Optical coherence tomography has become within the last years an established imaging technique with many applications in ophthalmology, and an important tool which contributes to earlier and more accurate diagnosis of glaucoma. As a consequence, detection sensitivity is highly valued. The aim of this study was to assess the reproducibility of peripapillary retinal nerve fiber layer (RNFL) thickness measurements by the Stratus Optical Coherence Tomograph (OCT) using the Fast- and Repeat-scan protocols in normal and glaucomatous eyes.

Long-term results after transscleral diode laser cyclophotocoagulation in refractory posttraumatic glaucoma and glaucoma in aphakia.

Purpose: To evaluate the long-term effect and safety of transscleral diode laser cyclophotocoagulation (TDLC) in eyes with advanced glaucoma in aphakia and posttraumatic glaucoma.

Patients And Methods: Twenty-one eyes of 21 patients with glaucoma in aphakia and 25 eyes of 25 patients with posttraumatic glaucoma were treated with TDLC between 1996 and 2004. If the intraocular pressure (IOP) remained above 21 mmHg despite medication for more than 4 weeks after TDLC, the procedure was repeated.
