Improving optometry as a profession leads to a PhD

Dr Nashua Naicker, lecturer and Chairperson: Learning and Teaching Committee (SoHRS) in the Department of Optometry, UFS School of Health and Rehabilitation Sciences, graduated on Thursday (April 18) with the degree Doctor of Philosophy in Health Professions Education.

A strong need to improve the general standing of optometry as a profession and to create lifelong learning opportunities for locally trained optometrists beyond what currently exists, is what led Dr Nashua Naicker to pursue a PhD in this field.

Dr Naicker, lecturer, and Chairperson: Learning and Teaching Committee (SoHRS) in the Department of Optometry, UFS School of Health and Rehabilitation Sciences, says he feels an overwhelming sense of relief with a keen sense accomplishment by achieving what he set out to through persistence in the face of adversity.

He graduated on Thursday (18 April) at the Faculty of Health Sciences April graduation ceremony with the degree Doctor of Philosophy in Health Professions Education through the Division of Health Sciences Education. “I am pleased and hope to change the narrative on this new path as an accredited researcher from ‘how long are you going to take to finish?’ to ‘what have you learnt in this journey?’. We are far too focused on chasing a timeline rather than focusing on the contribution that one makes and the self-development in this journey of discovery,” says Dr Naicker.

His supervisor was Prof Alvin J Munsamy from University of KwaZulu-Natal (UKZN) and co-supervisor Dr CB Written from the UFS.

Need for educational expansion

His research was focused on establishing a framework for postgraduate programmes in specialty fields of optometry for South Africa. The investigation was carried out with practising optometrists as the primary stakeholders and with optometric academics as the custodians for education and training in the country.

“With an overwhelming need for educational expansion found in this investigation, a conceptual framework was proposed as the innovation to take the profession forward in South Africa. Improving patient care from being upskilled and receiving professional recognition for the additional competencies and proficiencies that would be gained, was the motivating factors identified by optometrists to consider further education and training,” says Dr Naicker.

According to him, being in the educational fraternity for almost two decades and as a former education committee member of the professional board of optometry, he was able to see where the shortcomings were in the profession which set him on this path to pursue this research. With most optometrists in clinical practice and no clinical postgraduate qualifications available except pure research-based qualifications in SA, Dr Naicker explains that this hindered optometrists’ professional trajectory and career path opportunities into various special interest areas.

“By developing a framework for horizontal articulation pathways towards coursework postgraduate qualifications in various clinical specialty fields, this would be the contribution in addressing the educational gap that would guide higher education institutions in their programme development process. The beneficiaries of this expansion would not only be the health professionals but the patients who access optometric care from the optometrists who would have advanced skills and competencies to deliver comprehensive eye care services.”

Stayed motivated

Dr Naicker says the journey to his PhD was challenging from the outset as the country went into hard lockdown due the COVID-19 pandemic just five weeks after he registered for his PhD. Working on a PhD was not a priority at the time when your survival and that of your loved ones was uncertain as thousands of people fell victim to the coronavirus. Further to this, he continues, multiple changes to his supervisory team and the overhaul and revitalisation of the administration and management of the UFS Division of Health Sciences Education, also impacted his progress in his doctoral research at that time. He had felt despondent after a year of being registered when stability arrived with supervisory assistance that re-ignited his drive to pick up the slack and keep moving forward.

“The words ‘push through it’ were verbalised to me by a stranger I met in passing. While chatting about research I found those three words to be so profound and with such depth that they resonated with my experience of facing adversity but remaining vigilant to preservere and not drop the baton in the race against time to conclude my research. Gaslighting yourself and questioning your potential to complete a PhD only compounds your procrastination which was all too apparent. The goal is to rise above the self-doubt, brush off the devil with the fork sitting on your shoulder and just ‘push through it’.”

Dr Naicker, who is currently supervising four master’s of optometry students in their research undertaking, as well as undergraduate research projects, says he is in the process of publishing the research manuscripts generated from his PhD and is also part of a task team with the professional Board of Optometry for setting up the board exams for foreign-qualified optometrists. He would also like to work on research involving educating the educators of visually impaired learners.

Africa's Black Rhino conservation strategy must change

The conservation strategy of the black rhino in Africa needs to change in order to protect the species from extinction, a group of international researchers has found. The study that was published in the Nature Scientific Reports reveals that the species has lost an astonishing 69% of its genetic variation.

South African researchers took part
The researchers, which included local researchers from the National Zoological Gardens of South Africa (NZG), have highlighted the fact that this means the black rhino is on the brink of extinction. "We have found that there is a decline in genetic diversity, with 44 of 64 genetic lineages no longer existing," said Prof Antoinette Kotze, the Manager of Research and Scientific Services at the Zoo in Pretoria. She is also affiliate Professor in the Department of Genetics at the University of the Free State and has been involved in rhino research in South Africa since the early 2000s.

DNA from museums and the wild
The study compared DNA from specimens in museums around the world, which originated in the different regions of Africa, to the DNA of live wild animals. The DNA was extracted from the skin of museum specimen and from tissue and faecal samples from animals in the wild. The research used the mitochondrial genome.

"The rhino poaching ‘pandemic’
needs to be defeated, because
it puts further strain on the genetic
diversity of the black rhino.”

Ability to adapt
Dr Desire Dalton, one of the collaborators in the paper and a senior researcher at the NZG, said the loss of genetic diversity may compromise the rhinos’ ability to adapt to climate change. The study further underlined that two distinct populations now exists on either side of the Zambezi River. Dr Dalton said these definite populations need to be managed separately in order to conserve their genetic diversity. The study found that although the data suggests that the future is bleak for the black rhinoceros, the researchers did identify populations of priority for conservation, which might offer a better chance of preventing the species from total extinction. However, it stressed that the rhino poaching ‘pandemic’ needs to be defeated, because it puts further strain on the genetic diversity of the black rhino.

Extinct in many African countries
The research report further said that black rhino had been hunted and poached to extinction in many parts of Africa, such as Nigeria, Chad, Cameroon, Sudan, and Ethiopia. These rhino are now only found in five African countries. They are Tanzania, Zimbabwe, Kenya, Namibia, and South Africa, where the majority of the animals can be found.
