Agreement between peripheral anterior chamber depth evaluation using the van Herick technique and angle width evaluation using the Shaffer system in Japanese

Abstract

The van Herick technique closely coincided with the Shaffer system and was found to have a potential for use as a simple method for evaluating narrow-angle eyes in Japanese.

Anterior chamber measurements using Pentacam rotating Scheimpflug camera

“…Studies have shown good performance of limbal anterior chamber grading for detecting occludable angles. [20][21][22][23] The Pentacam rotating Scheimpflug camera is useful for screening patients because important parameters, especially chamber angle in different positions, ACD, pachymetry, corneal radii and diameter, and lens position, can be evaluated in 1 examination within a very short period with good reliability. Our results suggest that central ACD only slightly indicates the potential risk for the development angle-closure glaucoma because a great range of variation was observed.…”

Comparison of techniques for measuring anterior chamber depth: Orbscan imaging, Smith’s technique, and van Herick’s method

“…Kashiwagi et al reported a close relationship between LCDvh and Shaffer grading systems[25]; (ii) mean ACD for the two Orbscan comparisons. That is, Orbscan versus Smith's technique using a constant of 1.40 (x-axis)(Fig.…”

The Peterborough scheme for community specialist optometrists in glaucoma: a feasibility study

“…[21][22][23] Van Herick's peripheral anterior chamber depth assessment was therefore incorporated into the study at this stage, somewhat controversially, in preference to SOG performing gonioscopy, which was excluded. Some studies suggested that Van Herick's technique correlates more closely with occludable angles than direct gonioscopy when compared using high-resolution anterior segment OCT. 16,17 Patients had direct gonioscopy in the HES when judged appropriate by the ophthalmologist. To comply with the new NICE guidelines, we have started training the SOGs on gonioscopy.…”
