A guarded light pipe for direct visualization during primary scleral buckling on the Ngenuity platform [PDF]
Background Visualization during scleral buckling is traditionally achieved via indirect ophthalmoscopy. Recent advances have utilized the surgical microscope and a 25 gauge cannula-based endoillumination system, also known as a Chandelier lighting system.
