Munsamy","doi":"10.4102/aveh.v83i1.910","DOIUrl":"https://doi.org/10.4102/aveh.v83i1.910","url":null,"abstract":"Background: South Africa (SA) has postgraduate research-based master’s and doctorate qualifications in optometry with no clinical coursework qualifications in special interest fields. As a result, it hinders professional growth and career path for optometrists and further limits patients’ access to various care pathways from would-be upskilled optometrists.Aim: To explore optometrists’ perspectives on postgraduate programme development in special interest fields of optometry for SA.Setting: Study population of practicing optometrists registered with the Health Professions Council of South Africa (HPCSA).Methods: A quantitative cross-sectional descriptive design was employed, utilising an online questionnaire developed with the Evasys survey system v8.2. Non-probability sampling was used to access eligible participants.Results: From 424 survey responses, 83.5% had undergraduate qualifications and 95.5% worked in patient-facing environments. Participants responded positively (88%) to this need for educational expansion. Educational needs in Ocular Disease (75.6%), Paediatric Optometry (66.4%), Binocular Vision (65.1%) and sub-specialties of myopia control (41.2%) and Specialised Contact Lens Fitting (31%) were reported. With combined ‘highly important’ and ‘likely important’ responses, participants indicated that obtaining professional recognition (94.9%) and to improve patient care (98.8%) were the main drivers for pursuing additional education and training.Conclusion: A notable demand was found for coursework postgraduate programmes by the study populations from which professional recognition can be awarded in various special interest fields of optometry. The benefit of improved patient care from upskilled optometrists was expressed.Contribution: The findings would contribute towards the development of a conceptual framework for postgraduate education and training for optometrists in SA.","PeriodicalId":7694,"journal":{"name":"African Vision and Eye Health","volume":"105 27","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141666115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The EyeQue personal vision tracker (EPVT) was created as a convenient smartphone refractometer to be used at home and order spectacles online thereafter. However, its accuracy in diagnosing refractive error has not been fully established.Aim: This study aimed to determine the accuracy of the EPVT in measurement of refractive error and determine user perception on device use.Setting: University of KwaZulu-Natal optometry clinic, Westville campus.Methods: This was a comparative cross-sectional study using a double-blind design. Objective, non-cycloplegic refraction testing results using the EPVT were compared with gold standard ophthalmic subjective refraction (SR). Both eyes were considered for the analysis with comparisons being made between EPVT and gold subjective standard refraction for each eye. User perception was evaluated by means of a structured questionnaire.Results: The mean spherical equivalent refractive error was –0.18 ± 0.70 dioptre (D) and –1.12 ± 2.79 D for the gold standard ophthalmic SR and EPVT, respectively, with significant differences in visual acuities yielded by the two methods (p = 0.000). Participants preferred gold standard refraction testing over the EPVT.Conclusion: The EPVT was not accurate in measuring refractive error; therefore, the resultant prescription from EPVT alone should not be used to order spectacles. However, this digital tool presents promise as an autorefractor for screening refractive error rather than as a diagnostic device.Contribution: This study offered valuable insights into the prospective utility of home-based, self-administered smartphone refractive error testers as a tool for screening of refractive error. The study also provided cautions to the EPVTs limitations related to accuracy and limited ocular health assessment, which have broader implications for visual health and quality.","PeriodicalId":7694,"journal":{"name":"African Vision and Eye Health","volume":" 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140991897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meibomian gland dysfunction is a multifactorial and complex disorder of the ocular surface.Aim: This study aims to evaluate the characteristics of the meibomian glands in individuals living with HIV and AIDS undergoing antiretroviral therapy.Setting: The study was conducted at the antiretroviral (ARV) clinic, Mankweng Hospital.Methods: This was a prospective study conducted with 37 HIV and AIDS participants and 20 healthy controls. All participants were assessed using the Ocular Surface Diseases Index (OSDI) score and, tear break-up time and lid margin regularity (using the slit-lamp biomicroscopy). The loss of the meibomian glands was evaluated using the Marx’s line.
