Overview
Retinal vein occlusion is the second leading cause of vision loss, occurring at a rate of 100,000 cases annually. Current methods do not address the source of the occlusion, namely, the blood clot that has become trapped in the small (~100µm) retinal blood vessel. Due to the small vessel size, fragility of the surrounding tissue, and difficulty in reaching the site of occlusion, free-hand surgical procedures have proven impossible. Preliminary work done with the steady hand robot has shown that robot-assisted retinal vessel cannulation is possible and may be the solution. This procedure would involve puncturing the small vessel upstream of the clot and delivering a clot dissolving medicine – all with the assistance of a steady hand robot to provide the precision and tremor-free stability that is required. We propose to determine the feasibility of robot assisted retinal vessel cannulation surgical procedure using bent tip pipette in a realistically simulated surgical environment.
