Dr Erasmus obtained his specialist degree through the Fellowship of the College of Ophthalmologists of South Africa in 2017. During this time Dr Erasmus also obtained his Masters in Medicine in Neuro-ophthalmology by research report in 2017 through the University of Witwatersrand. The MMED topic was titled: “A Contextual Analysis of Pupil-Involving Oculomotor Nerve Palsies in Two Tertiary Hospitals in South Africa”. This research highlighted the sensitivity of Computerized Tomographic Angiography (CTA) in ruling out posterior communicating artery aneurysms in patients presenting with pupil-involving third nerve palsy.
During registrar training he offered his surgical expertise to the Bureau for the Prevention of Blindness and has completed 10 "blind tours" all over South Africa helping to restore the sight of more than 300 patients in need of cataract surgery in the community.
