Screening for refractive errors in 6-9 month old infants by photorefraction.
, 1984 The method of isotropic photorefraction has been used in a trial of refractive screening of 6-9 month old infants. Data are presented on the calibration of the method against retinoscopic measurements and its reliability.

European Journal of Inorganic Chemistry, Volume 28, Issue 15, May 28, 2025.The photochemical reaction of [Ru(phen)2{(ClCH2)2bpy}](OTf)2 (OTf− = CF3SO3−) in water, an alcohol, or acetic acid [ROH; R = H, Me, Et, 1‐Pr, 2‐Pr, or Ac] afforded [Ru(phen)2{(ROCH2)2bpy}](OTf)2 and two moles of HCl per Ru(II) complex. These photoproducts are characterized by elemental analysis and 1H NMR spectroscopy. Crystal structures of [Ru(phen)2{(

Increasing myopia in Scotland at age of 3.5–5.5 years: A retrospective epidemiological study
Ophthalmic and Physiological Optics, Volume 45, Issue 3, Page 834-844, May 2025.Abstract Purpose Scotland has comprehensive child vision screening at age 3.5–5.5 years of age, with ~85% participation (40,000–50,000 screening episodes annually). Orthoptists deliver the screening, including presenting vision, cover test and other tests. Screening failures are referred for eye examinations, including cycloplegic refraction. The study

Fulminant toxoplasmic retinochoroiditis following intravitreal triamcinolone administration
Indian Journal of Ophthalmology, 2012 We report two cases of fulminant toxoplasmic retinochoroiditis following intravitreal triamcinolone acetonide (IVTA) administration. Case 1: A 42-year-old female received IVTA for presumed non-infectious panuveitis. Within 2 months, she developed diffuse

Photorefractive Solitons [PDF]
Optics and Photonics News, 2002 The story has it that, when Schwinger learned of the Feynman diagrams, he remarked that quantum electrodynamics had been brought to the masses. A similar statement could be applied to photorefractive (PR) solitons. In fact, among the family of known optical self-trapped waves, PR solitons are of an altogether peculiar nature: they are the consequence ...

Detection of significant vision conditions in children using QuickSee wavefront autorefractor
Ophthalmic and Physiological Optics, Volume 44, Issue 3, Page 501-513, May 2024.Abstract Purpose This study evaluated the ability of QuickSee to detect children at risk for significant vision conditions (significant refractive error [RE], amblyopia and strabismus). Methods Non‐cycloplegic refraction (using QuickSee without and with +2 dioptre (D) fogging lenses) and unaided binocular near visual acuity (VA) were measured in 4‐ to ...

Comparison of the PlusoptiX A16 and vision screener V100
Frontiers in OphthalmologyClinical relevanceThis study compares a novel photoscreening device with a previously validated one in a school-age population. It highlights a tendency of the new device to underestimate myopic spherical equivalent and overestimate hyperopic cases ...

The Performance of Spot Photoscreener in 6 to 10 Weeks Infants in China: A Cross‐Sectional Study
Journal of Ophthalmology, Volume 2024, Issue 1, 2024.Purpose. To compare the refractive errors measured by the Spot photoscreener (with or without cycloplegia) to cycloplegic retinoscopy in 6‐ to 10‐week‐old infants. Materials and Methods. 101 right eyes from 101 healthy infants aged 6 to 10 weeks were recruited for this cross‐sectional observational study.
