Mydriasis as a Secondary Effect in Patients With HLA‐B27–Associated Uveitis

Medicine Advances, Volume 4, Issue 1, Page 12-19, March 2026.
HLA‐B27‐associated acute anterior uveitis causes significant inflammation of the iris and anterior chamber, which disrupts normal parasympathetic control and results in increased sympathetic tone leading to pupil dilation (mydriasis). This finding can sometimes resemble herpetic uveitis, making a clinical context and careful evaluation crucial for ...

The effect of cycloplegia in the accuracy of autorefraction, keratometry and axial length using the Myopia Master

BMC Ophthalmology
Background Assessing refractive errors under cycloplegia is recommended for paediatric patients; however, this may not always be feasible. In these situations, refraction has to rely on measurements made under active accommodation which may increase ...

Compensated versus uncompensated millimeters during myopia progression: Estimating H′ in children

Optometry and Vision Science, Volume 103, Issue 1, January 2026.
ABSTRACT Purpose The second principal point (H′) of the eye can be used to estimate the diopters of change in refractive error that result from each millimeter of axial elongation. Calculating the location of H′ requires data from phakometry, a technique not included in most myopia control clinical trials.

Comparison of cycloplegia with atropine 1% versus cyclopentolate 1%

Indian Journal of Ophthalmology, 2023
Purpose: Cycloplegic refraction is mandatory for children to know the eye's refractive status. In this study, we compared cycloplegia induced by cyclopentolate 1% to that induced by atropine 1% by means of retinoscopy.

Intraocular Pressure Increase Induced by 0.5% Tropicamide‐0.5% Phenylephrine in Dogs: An Analysis of Causes Using Ultrasound Biomicroscopy

Veterinary Ophthalmology, Volume 29, Issue 1, January 2026.
ABSTRACT Purpose To determine whether the differences in intraocular pressure (IOP) change after the topical application of 0.5% tropicamide and 0.5% phenylephrine (TP) are due to anatomical variations in the anterior chamber using ultrasound biomicroscopy (UBM).
