Does astigmatism alter with cycloplegia?

Journal of Current Ophthalmology, 2016
To determine the effect of the cyclopentolate 1% on the cylindrical and spherical components of the refraction.Three hundred seventy-five eyes of 195 subjects, including 74 males and 121 females, aged from 3 to 59 years were refracted before and 30 min after cyclopentolate 1% eye drop instillation. To compare cylindrical data, power vector analysis (J0

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 ...

Compensation for axial elongation during multifocal soft contact lens wear: Results from the BLINK study

Optometry and Vision Science, Volume 103, Issue 3, March 2026.
ABSTRACT Purpose To determine the effect of +2.50 D add multifocal soft contact lenses (MFSCLs) compared to +1.50 D add and single vision contact lenses (SVCLs) on the relationship between axial elongation and myopia progression. Methods Individual estimates of D/mm were derived from the CLEERE Study, then applied to data from 289 participants in the ...

Feasibility and accuracy of school‐led vision screening in primary and secondary school students within the United Kingdom

Optometry and Vision Science, Volume 103, Issue 2, February 2026.
ABSTRACT Purpose Vision screening occurs once in United Kingdom (UK) children on school entry, but has recently been withdrawn in some areas. Consequently, significant refractive error and/or vision problems may go undetected. School‐led vision checking, where school staff assess vision, is increasingly advocated by the International Agency for the ...
