Tear meniscus height agreement and reproducibility between two corneal topographers and spectral-domain optical coherence tomography.

Clinical Relevance: Tear meniscus height (TMH) is an important clinical marker in dry eye diagnosis and management.

Purpose: To evaluate the reproducibility and agreement of TMH measurements in non-clinical participants using the Oculus Keratograph 5 M, Medmont Meridia, and Spectral-domain optical coherence tomography (Spectralis SD-OCT).

Methods: Fifty-six participants (mean 43.

Comparison of different measuring methods in the assessment of the ISNT rule and its variants in a normal population: A cross-sectional study.

Purpose: The aim of this study was to compare five different neuroretinal rim (NRR) measurement methods, based on quadrants and NRR widths, in the assessment of the ISNT (inferior (I) > superior (S) > nasal (N) > temporal (T)) rule, and its variants IST (inferior (I) > superior (S) > temporal (S)) rule, IS (inferior (I) > superior (S)) rule and T (temporal is the thinnest) rule in a normal population. Factors influencing compliance with this rule and its variants were also evaluated.

Methods: Stereoscopic fundus images were analysed through a dichoptic viewing system.

Optic Disc Localization in Retinal Images Based on Cumulative Sum Fields.

This paper describes an automatic method for the optic disc localization in retinal images, which is effective and reliable with multiple datasets. Particularly, the described method reveals very effective dealing with retinal images with large pathological signs. The algorithm begins with a new vessel enhancement method based on a modified corner detector.
