There's a definite market for it drops is normally the first option for Glaucoma but the disease is progressive & as mentioned compliance is poor & it does require a certain amount of manual dexterity which may be absent in some older patients.
Next is stents which I had when I had the cataracts done as it's an easy option. They worked really well until I had a detached retina then they stopped working no idea why maybe they got blocked or something. Anyway back on eye drops & SLT which worked really well, there is a Medicare code for SLT & it's done in the specialists surgery (not hospital) no sedation required & it can be repeated every year with multiple claims to Medicare. It's not pleasant but tolerable.
Canaloplasty seems like the way forward but I get seen every 6/12 & nobody has even mentioned it so it clearly needs more publicity
