A recently filed patent (Publication Number: US20230363941A1) outlines a method and apparatus for delivering medication into the eye of a patient. The method involves inserting a hollow conduit into the eye until it reaches a specific reference location, confirming its positioning, and then extending it further into the injection region of the eye to convey the medicament. The confirmation of the conduit’s placement can be done by measuring pressure or light emissivity gradient within the eye. Additionally, the apparatus described in the patent includes a housing with an actuator, a hollow conduit, a measurement device, and an injection controller to deliver the medication effectively.

Furthermore, the patent details a method that involves inserting a hollow conduit and a catheter into the eye to deliver medication into a specific region between the sclera and the retina. By inflating a balloon attached to the catheter, a space is created or expanded within the region, allowing for the injection of the medicament. The method also includes steps to ensure the conduit is in the correct position within the eye, with the option to hydrodissect the sclera and choroid for separation. The patent also introduces a method using optical fiber and a detector to identify the conduit’s location in the eye, enabling precise delivery of the medication into the target injection region. The use of Optical Coherence Tomography (OCT) is also mentioned as part of the measurement device in the apparatus.
