Understanding your CPD commitment

Accreditation Number: ODO ODO/002/002/02/2020 Want to take the CPD quiz? Once you are ready, you can enroll below. Good luck! 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…

Convergence insufficiency

Article: Courtesy Essilor – Points du Vue
One 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.

OCT and retinal pathologies

Courtesy Points du Vue – Essilor
The field of retinal imaging has evolved very rapidly over the course of these past few years. 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.

Managing common ocular injuries at primary health care level

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 …

Literature Review: Atropine for Myopia Control

By Chantel van Wyk
In 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…

Using red-green anaglyphs in the management of convergence insufficiency

By Prof Paul Ramkissoon
Convergence 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…

High Myopia: the specificities of refraction and optical equipment

By Christian Franchi, Adèle Longo & Dominique Meslin
The specific needs of highly myopic patients require special attention from Eye Care Professionals. This article describes both the visual discomfort and primary visual disorders associated with high myopia and explains the risks of visual impairment. It also discusses the specificities of refraction and the choice of optical equipment. In addition, it makes recommendations on frame selection and advises on the optimal selection of ophthalmic lenses. In recent years

Hereditary ophthalmological pathologies in children – 2CPD points

By Josseline Kaplan & Jean-Michel Rozet
Hereditary vision pathologies in children affect all ocular structures. Although of a varying degree of severity, they all impact the sense considered most sacred, justifying the intense amount of research that has been undertaken over the past three decades. A great deal of progress has been made, whether in terms of severe malformations of the anterior chamber or degenerative and inexorably developing pathologies of the retina. This progress has resulted…

Ethical issues to ponder

By Chris Faul OD
One can only wonder how it came about that optometric practices in South Africa started adopting commercial names, in spite of the HPCSA rules dictating otherwise. Moreover, what is to be achieved with these names? Will they entice the consumer? I am reluctant to pull some names out of the hat as examples in fear that I may offend some practitioners who are in fact using these names. But let me play it safe by erring on the ridiculous with names such as Square Eyes Optometrists, Round Eyes Optometrist and Optical this and Spectacle that. As it is, it is difficult to attain a differential advantage…
