The start of 2017 is a good time to reflect on the success of the College’s journal Ophthalmic and Physiological Optics (OPO). Like all academic publications is it ranked by its impact factor and although this ranking is not without its flaws it is a useful ball park indicator of a journal’s quality. Members should be proud of the influence and scientific regard of our publication in disseminating leading research. The most commonly used assessment of ‘quality’ is that of the Institute for Scientific Information, journal impact factor score. Over a two year period OPO was ranked 2.6 making it 15th of 56 journals in the ophthalmology category in the world. Another metrics also highly ranks OPO: Scimago ranked it first out of nine within optometry and 23rd out of 109 in ophthalmology globally. This new issue of OPO covers a wide variety of topics; here is a small selection of papers especially relevant to practicing clinicians. 

An area which affects us all in practice is examining children. A paper by McCullough et al investigates the examiner repeatability of cycloplegic retinoscopy; the paper sets out how much difference can be considered significant. Another paper by Troyer et al suggests an animated movie may be a suitable target for the measurement of phoria in pre-school children. Following the publication of a systematic review of the evidence relating to coloured overlays last summer, the topic has been widely debated by practitioners and academics alike. All agree more research on the topic would be beneficial, but that is where the common ground ends. This edition contains letters by Evans and Wilkins who set out their considered opinions about the previous review, with a subsequent response from the authors Barrett et al

Members should be proud of the influence and scientific regard of our publication in disseminating leading research.

This January’s edition of OPO, saw the publication of a significant piece research by Crabb et al. Their research suggests at least one in five patients in glaucoma clinics across England, referred with a visual field defect, had advanced loss  a broadly stable figure despite increasing take up of sight tests and advances in the ability to detect glaucoma. It is significant that they have found for the first time that that a man is, on average, 16% more likely to be one of those affected by the advanced loss at the time of diagnosis. This may confirm many practitioners’ anecdotal view and the stereotype that men are too casual about, and disinterested in, routine health checks. The authors point out that, although it is statistically significant and may affect future health service delivery, this finding is not large enough to have an impact individual case finding decisions.
