Lawn bowls are all about judging the distance to the jack and delivering the wood at the required “weight.” Good vision and depth perception would obviously be important elements. In order to have depth perception, you must have binocular vision, also known as stereopsis. Indeed, depth perception is the ability to perceive the world in three dimensions and to judge the distance of objects. The most important aspect of binocular vision is having two eyes; people relying on the vision from only one eye…

  As Editor of Vision, all too frequently, I receive queries about the ins and outs of CPD. It stands to reason, a full understanding of the CPD rules, as laid down by the HPCSA, is of paramount importance in order to manage your commitment effectively. Audits do happen,  and mostly

Article: Courtesy Essilor – Points du VueOne of the most common disorders of binocular vision encountered in the eye clinic is convergence insufficiency (CI). Population studies estimate upwards of 8% of the population suffer from convergence insufficiency, with the incidence increasing with age. Convergence insufficiency results with vergence ability at near is unable to match vergence demand. When this occurs, sensory fusion may be disrupted leading to intermittent diplopia, asthenopia, and fatigue. Clinicians should be able to quickly screen for abnormalities in convergence ability of a patient and provide a thorough evaluation of binocular ability when indicated. Many patients will respond well to vergence therapy, leading to both an increase in fusional vergence ability and a subsequent decrease in symptoms.

After angiography (with fluorescein and indocyanine green) used for exploration of the vascular network of the retina, the appearance of optical coherence tomography (OCT) at the end of the nineties, was the second revolution in retinal imaging. Firstly Time Domain, and now today Spectral Domain, this non-invasive examination, without any counter-indication, is used to analyse the retinal structure with a resolution of 5 to 7μm and has become an essential examination in the diagnosis and monitoring of mainly macular medical-surgical retinal pathologies.

It is a well-known dry eye questionnaire. Ever wondered whether the long hours in front of the computer is causing you any harm? Or if the gritty feeling is due to allergy or dry eyes? Seek no further – the OSDI will help. The questionnaire was created by the Outcomes Research Group at Allergan Inc, in order to…

Peripheral corneal desiccation (PCD) or 3 and 9 o’clock staining is the horizontal drying of the cornea and/or on the adjacent conjunctiva displaying a hallmark fluorescein stain. Both types cause mostly conjunctival redness and, sometimes, conjunctival oedema. The common subjective symptoms vary…

By Siphokazi Dludla Eye injuries are very common and can lead to severe visual impairment and blindness. They are most likely to occur in a work place, sports or as a result of assault. Studies show that males have a high incidence of eye injuries compared to females. Millions of people in the world have gone blind as a result of ocular injuries, therefore health care providers (in primary level) both public and private sector should have clear knowledge and skills on how to manage ocular injuries. This article briefly outlines …

By Chantel van WykIn the review by Foster and Jiang (2014), who summarised the incidence, prevalence, and progression of myopia, it is clear that myopia is an epidemic. Myopia can lead to significant and irreversible vision loss. This calls for urgent intervention of successful myopia control. According to the literature of the last decade, atropine eye drops proves to be one of the most effective treatments to limit myopia progression. The use of atropine for controlling myopia…

By Prof Paul RamkissoonConvergence Insufficiency (CI) is a condition in which the patient has a reduced ability in keeping the alignment of the eyes and maintaining binocular fusion on a near object. This inability to sustain convergence causes the patient to use just one eye at a time, or to see double. Commonly, CI is accompanied by…
