Intraocular trimming of Ahmed glaucoma tube

Trim Ahmed GV tube

This aphakic patient presented with elevated intra-ocular pressure many years after Ahmed Glaucoma Valve implantation performed by a colleague of mine. Some vitreous had found its way into the tip of the tip that extended beyond the pupillary margin. As these glaucoma tubes are, as Dale Heuer has referred to them, divining rods for vitreous, it is not surprising that this happened. Watch this video to see how I ended up dealing with this.

Now 3 weeks since this surgery and her pressure is 18 mmHg on only the prednisolone drops for inflammation whereas it was 54 prior to surgery on glaucoma medications.
