Retinitis pigmentosa is an eye disease that people are born  with that slowly leads to vision loss. The Argus II retinal implant is the only  treatment approved by Health Canada for retinitis pigmentosa. A device is implanted  in a patient’s eye and it works with a special set of glasses to restore some  vision to people with this disease.
				
				In 2016, Health Quality Ontario published a health  technology assessment of the Argus II system. Based on that assessment, the Ontario Health  Technology Advisory Committee recommended against publicly funding the Argus II  system for individuals with retinitis pigmentosa. OHTAC requested a re-evaluation  after 1 year.
				
				We have now updated our assessment based on evidence  published since 2016. We assessed the clinical benefits and harms of the Argus  II system, value for money, and the budget impact of publicly funding it. We  also interviewed people who have used it to learn more about their  experiences. 
				
				Based  on new evidence, the Argus II retinal prosthesis system improved visual  function and quality of life in patients with advanced retinitis pigmentosa. The  Argus II system is expensive, but the cost to publicly fund it would be low  because of the small number (4) of eligible patients. The Argus II  system can only enable perception of light/dark and shapes/objects, but these  advancements represent important gains for people with retinitis pigmentosa in  terms of mobility and quality of life.
				
				It would cost the  province $0.71 million to $0.78 million per year to fund the Argus II system,  assuming 4 implants per year.
				
			 
			
			
			
			
			
				
				
					
The Ministry of Health and Long-Term Care has accepted this recommendation.
				
				
				The Ministry of Health and Long-Term Care has provided the following response:  In 2018/19, the Ministry is providing funding for Argus II retinal prosthesis system implantations at the University Health Network.
