ABSTRACT
Gas filled eye surgery is a part of treatment for vitreoretinal diseases such as retinal detachment and macular hole surgery. The patient compliance to maintain the correct position after treatment with gas filling procedure is one of key factor for successful of surgery treatment which helps to restore the vision. The objective of this study is to describe an innovation of eye shield that may improve the positioning compliance for gas filled eye patient and to demonstrate its reliability.The experiment was designed to assess the agreement of the different angles compared to a commercial inclinometer. The angulation was evaluated at 0°, 15°, 30°. 45°, 60°, 75°, 90°, 105°, 120°, 135°, 150°, 165° and 180°. The data analysis shows that the proposed devices have the same measurement as the standard measurement with an Intraclass correlation of >0.99.
