The Patching Process
Patching of a child's eye must only be conducted after a full dilated examination by an Ophthalmologist (eye doctor). You will be instructed to patch the child's eye for a certain number of hours per day. The Ophthalmologist and Orthoptist will then monitor the patching treatment. It is vitally important that you do no more or less patching than has been prescribed by your clinician; they will be using an evidence based treatment plan. Never conduct patching yourself as you may damage your child's eyesight.
It is important you accurately record the patching time as the clinician needs to assess the vision achieved with the quantity of patching done to know how much more patching is required. There is evidence that up to 250 hours of patching is required, but the actual amount is to be determined by your Doctor and Orthoptist and may be more or less than 250 hours. (Ref.
