Test and evaluation of the 2.4-micron photorefractor ocular screening system [PDF]
An improved 2.4-m photorefractor ocular screening system was tested and evaluated. The photorefractor system works on the principal of obtaining a colored photograph of both human eyes; and, by analysis of the retinal reflex images, certain ocular ...

Hyperopia in preschool and school children
Medicinski pregled, 2007 Hypermetropia (hyperopia) is a refractive error of the eye in which parallel light rays focus behind the macula luthea without accommodation giving an unclear retinal image. The involvement of accommodation in correction of far-sightedness leads to the following three clinical types of hyperopia: total, latent and manifest.

Accuracy and precision of a sphero‐cylindrical over‐refraction app for smartphones
Ophthalmic and Physiological Optics, EarlyView.Abstract Purpose To evaluate the accuracy and precision of a web‐based smartphone app designed to measure sphero‐cylindrical over‐refraction. Methods A total of 307 healthy young subjects (22.5 ± 3.4 years) underwent clinical subjective refraction. In addition to each subject's refractive correction, spherical and cylindrical errors from −1.50 to 0.00 ...

Factors predicting myopia incidence in China and Europe
Ophthalmic and Physiological Optics, EarlyView.Abstract Aims To develop a predictive model for myopia incidence using population‐based data from Chinese and European children. Methods Analysis of four longitudinal studies from the UK, Sweden and China was conducted. Data from 4405 non‐myopic children aged 6 to 16.8 years with spherical equivalent (SE) refraction from −0.49 D to +10.00 D were ...

The Waterloo Differential Acuity Test (WatDAT)—Testability and normative data
Ophthalmic and Physiological Optics, EarlyView.Abstract Purpose To investigate the testability of the WatDAT for measuring recognition visual acuity (VA) in children aged between 18 to 48 months, report preliminary age‐related data and compare with two commercially available matching tests. Methods A total of 57 children (18.5–45.8 months) attended for two sessions.

Ophthalmic and Physiological Optics, EarlyView.Abstract Purpose To assess second‐year myopia progression in children after a 1‐year randomised controlled trial of individualised ocular refraction customisation (IORC) spectacle lenses, customised to each eye's peripheral refraction. Methods A total of 161 children were randomised to wear IORC lenses with high (+4.50 D, IORC‐H), medium (+3.50 D, IORC‐
