Peripheral retinal diseases encompass a diverse group of conditions that can impact visual health and function. While some of these conditions are asymptomatic and may have a benign course, others can progress to potentially sight-threatening complications, such as retinal detachment, especially in the context of visual symptoms. Careful clinical evaluation and timely intervention are essential in managing peripheral retinal diseases to prevent loss of visual acuity, particularly when predisposing risk factors are present. Obtaining a proper history may help identify some genetic conditions associated with higher incidence of retinal tears and detachment such as high myopia or Stickler syndrome. Other factors to consider include the new onset of symptoms of posterior vitreous detachment, prior history of trauma or relatively recent intraocular surgery such as cataract surgery, intravitreal injection or YAG capsulotomy.

Ravi Dookeran, MD, Department of Opthalmology, University of Manitoba, Winnipeg, MB

Dr. Dookeran has been working in Winnipeg since 2006 in the Misericordia Hospital and Winnipeg Clinic. He runs a surgical and medical Retinal practice serving all of Manitoba, Nunavut and western Ontario. After completing his medical school training at the University of Manitoba and ophthalmology residency in Edmonton at the University of Alberta, Dr. Dookeran went on to complete a 2-year surgical and medical Retina fellowship at McGill University. Dr. Dookeran is an Assistant Professor in the Department of Ophthalmology at the University of Manitoba and is actively involved in clinical research having authored numerous publications. He has served as Faculty Lead for the retina section of the ophthalmology residency program and on the Residency Program Committee for over 8 years. He received the “Teacher of the Year” award in 2017 for his excellence and commitment to teaching. As an active speaker, Dr. Dookeran has given lectures and spoken at conferences at a local, national and international level and even worked with The Learning Channel, participating in the medical educational series Doctorology with Canadian comedian Leslie Nielsen. Dr. Dookeran has served on the national board of the CNIB Patient Advocacy Committee for 3 years and continues to work with government to help create policies that benefit the lives of the visually impaired across Canada. Dr. Dookeran has been actively involved in developing a Teleophthalmology program and serves as the medical director of the Manitoba Retinal Screening and Vision Program (MRSVP). This service has been successfully running since 2004, covering much of Northern Manitoba and has become one of the largest across Canada.

Charbel Wahab, MD, University of Manitoba, Winnipeg, MB

Dr. Charbel Wahab is a surgical retina fellow at University of Manitoba – Misericordia Health Centre. He completed his medical degree as well as his Ophthalmology Residency at the University of Balamand in Lebanon. He has a Bachelor of Science in Biology from the University of Balamand. Dr. Wahab pursued his education and training by completing a Medical Retina Fellowship at the American University of Beirut in 2021-2022, followed by another Medical Retina and Uveitis Fellowship at the University of Toronto in 2022-2023. He has a clinical focus and interest in vitreoretinal diseases and retinal surgery. In addition, Dr. Wahab has a very keen interest in research and innovations in ophthalmology and has published several articles and presented at various meetings as well as participated in various extracurricular activities, committees, and volunteering.
