Video transcript:
In glaucoma, aqueous humour is unable to drain from the eye freely, which cases intraocular pressure to rise. The main drainage pathway comprises three structures, situated near the base of the iris. Aqueous humour drains through the trabecular meshwork, into Schlemm's canal, and then into collector channels, to leave the eye. In August 2019 I published a comprehensive review of the eye's drainage pathways, and how they can best be enhanced using micro-invasive glaucoma surgery. This was published in Survey of Ophthalmology, the flagship review journal for Ophthalmology. This is the iTrack device, it's a flexible, hollow microcatheter, just 220um in diameter, with an illuminated fibre optic tip. The iTrack microcathere is inserted into Schlemm's canal, and then advanced circumferentially 360 degrees. The illuminated tip allows the surgeon to know exactly how far the microcather has travelled. A sterile surgical gel called ophthalmic viscosurgical device is then injected. This flushes out and dilates open Schlemm's canal and the downstream collector channels. This rejuvenates the outflow pathway, allowing aqueous humour to drain from the eye more easily, and intraocular pressure to fall. The iTrack microcatheter is then withdrawn from the eye. This completes the procedure.
