Ophthalmic and Physiological Optics (OPO)

OPO - a leading international journal for contemporary research in vision science and optometry

OPO is the research journal of The College of Optometrists. It is read and cited around the world, and helps clinicians and educators stay up to date with the latest research findings on the development, use and restoration of vision.

What's in the latest issue of OPO?

OPO is published six times a year. Here are some highlights from the September 2022 issue of OPO

Learning retinoscopy: A journey through problem space

Jarrod Hollis et al. (2022)

While a relatively simple technique, retinoscopy is a complex skill to acquire. This study compared the strategies that novices, third-year students and experts use when performing retinoscopy, with the aim of identifying the key stages of learning that may enlighten teaching practice. The verbal protocols and cognitive strategies of novices, students and experts were recorded and then subjected to ‘problem space’ analysis, and the study found that the formation of sub-goals is an effective strategy to use when learning retinoscopy. It suggests that optometric education should place an emphasis on understanding, rather than simply the performance of a practical skill.

Patients’ and health professionals’ views on shared decision-making in age-related macular degeneration care: A qualitative study

Mariska Scheffer et al. (2022)

Recent evidence suggests signs of undertreatment and overtreatment, underdiagnosis and insufficient information provision in AMD care. Shared decision-making (SDM) can aid information sharing between patients and health professionals and enhances high-quality care. This research aimed to gain insight into patients' and professionals' views on SDM in AMD care, using semi-structured interviews. It flagged important challenges, including the limited time between diagnosis and initial treatment, and the potential for patients not to understand information provided about the nature, treatment and prognosis of AMD. It suggested that nurse practitioners could be involved in providing further information and answering questions to help with patient understanding and time constraints.

Size and position of the optic disc crescent in a white European population with myopia

David Hill et al. (2022)

One of the first clinically observed changes in the retina with progressing myopia is in the optic disc crescent. If a change is predictive of myopia progression, it could aid in myopia management interventions to target those at greatest risk of progression and subsequent ocular morbidity. This study investigated the type, dimension and appearance of optic disc crescents and how they relate to the level of myopia, looking at retinal photographs of healthy children and adults in 400 eyes from a white European population. It found that higher levels of spherical error were associated with increasing crescent size, and that inferior temporal crescents were associated with a higher degree of myopia and may be a potential marker for risk of greater myopic progression.
