Refraction under GA in children using cycloplegic refraction as a reference

The authors aimed to compare the measurements of cycloplegic refraction and refraction (R1-1) under general anaesthesia (GA) with automated refraction (ARF) in paediatric patients and to determine the impact of GA on accommodation. The study included 222 eyes of 222...

DIY IOP – does it work?

Measuring intraocular pressure (IOP) plays a major role in glaucoma care as IOP is a parameter, along with visual field progression and optic disc cupping used to assess treatment effect. While Goldmann tonometry (GAT) is the gold standard, it only...

Comparison of false-negative responses in glaucoma patients and normal observers

The authors compared false negative rates for full threshold (FULL) and Swedish Interactive Threshold Algorithm (SITA) standard automated perimetry in healthy control subjects and glaucoma patients. Twenty-four subjects underwent visual field testing of one eye five times within six weeks...

AC/A non-linearity

This study investigated whether or not the response accommodative convergence to accommodation (AC/A) ratio in 30 visually normal subjects is linear with lens presentation order counterbalanced. Accommodative response was measured using the Shin Nippon SRW 500 infrared autorefractor. Accommodation was...

Comparison of methods of central corneal thickness measurement in glaucoma

This prospective study was done to compare the accuracy and reproducibility of central corneal thickness measured by hand-held and disc-mounted ultrasound pachymeter in glaucoma patients. Sixty-five patients were included in the study. Patients with corneal diseases, corneal astigmatism >3 diopters...
