Dr. Sarah Ismail

Sarah Ismail is an ophthalmology researcher based in South Africa whose work spans clinical ophthalmology and global surgery. Affiliated with leading academic hospitals in Johannesburg, her research addresses eye disease in high-burden settings and broader questions of access to safe elective care worldwide. She collaborates in large international networks, contributing to multicountry studies published in prominent global health journals.

Her ophthalmic research focuses on retinal disease, HIV-related ocular manifestations, glaucoma diagnostics, and rare anatomical conditions such as nanophthalmos and microphthalmos. She has advanced understanding of population-specific retinal nerve fibre layer norms, evaluated cost-conscious anti-VEGF strategies for diabetic macular oedema, and examined evolving ocular patterns in the era of antiretroviral therapy, strengthening evidence for context-sensitive screening and management.

Beyond subspecialty ophthalmology, her work engages health systems research, including the impact of COVID-19 on surgical services in sub-Saharan Africa and global access to elective hernia care. This portfolio highlights strengths in multicentre collaboration, prospective cohort design, and systematic review methodology, with a consistent emphasis on equity, quality of care, and pragmatic solutions for resource-limited environments.
