Dr Ganga obtained his degrees from Madras Medical College, Chennai, India and advanced sub-specialty training from the Henry Ford Hospital, Detroit, USA. He specialises in the diseases and surgery of the eyelids, lacrimal system, orbit and oculofacial diseases. Committed to clinical and surgical excellence, he is a regional and international expert in disorders such as orbital trauma, ophthalmic oncology, congenital and acquired eyelid disorders, lacrimal system disorders, anophthalmic sockets, thyroid eye disease, facial palsy, etc. Some of his special interests include minimally invasive surgery (eg. endoluminal duct recanalisation(ELDR)), complex orbital trauma reconstructions (navigation surgery, bioresorbable implants and customized implants), medical and surgical rehabilitation of thyroid eye disease, and vascular lesions of the orbit.
Dr Ganga is part of the core faculty of the Department of Ophthalmology and heads the Orbit & Oculofacial Surgery Service at the National University Hospital (NUH). Dr Ganga was instrumental in starting various multidisciplinary services including the NUH Retinoblastoma service (with paediatric oncologists, neuro-interventional radiologists and pathologists), NUH Thyroid Eye Disease Service (with Endocrinologists & immunologists) and the NUH Lacrimal Service (with Rhinologists). He has trained Fellows from Singapore, Malaysia, Myanmar, Philippines, India, Thailand, Iran, Syria, the United Kingdom and Nepal.
Dr Ganga has won many awards for his work, including the American Academy of Ophthalmology Achievement Award, Asia Pacific Academy of Ophthalmology Senior Achievement Award, Ocular Trauma Excellence Award, Best Teacher Award as well as several International Orations and named lectureships.
Dr Ganga travels widely as a regional and international faculty at various orbital and craniomaxillofacial conferences, symposia and courses raising the level of care of orbital and orbitofacial disorder and has contributed chapters to several textbooks in his field. He serves in several leadership capacities in various national, regional and international professional societies. In addition to several scientific peer reviewed publications he has authored a book on 'Orbital Fractures – Principles, Concepts & Management' and co-authored a book on 'Ocular Adnexal Lesions – A clinical, pathological and radiologic correlation'.
