Here is a reminder to turn the foveal sensitivity “on” for your perimeter. Patient with a “normal” visual field test but with a macular hole with 20/150 visual acuity. Only the foveal sensitivity will flag this meaningful abnormality on standard automated perimetry.

Just did a laser iridoplasty to pull incarcerated iris out of a tube tip. Wish I could have filmed it! I used a 532nm laser, longish duration (0.3s), 400mw. Best part was watching the CO2 bubbles escape into the tube lumen as flow was reestablished.

Hope you guys can appreciate the detached retina and also a retinal hole.

I had the honor of speaking Vision Expo this AM with Justin Schweitzer on the topic of corneal biomechanics/hysteresis and IOP. It’s my favorite glaucoma rabbit hole. We also presented Sean McCafferty, MD FACS data on the CATS tonometer.

One thing that blows my mind is how frequently patients will have central corneal thicknesses that equal, e.g. 534 microns - bilaterally. The fellow eyes developed separately, but with enough precision to match each other within a micron.

There s a touch of irony in the fact that I am a glaucoma specialist and take diamox when I ski at altitude, pilocarpine for presbyopia and occasional brimonidine for eye redness or to improve contrast sensitivity/night vision w my large pupils. And beta blocker for HTN lol.

This OCT artifact took me a second. The first image is an inverted (captured too close) RNFL. The segmentation mostly worked (upside down) but the acquisition image w the upside down nerve and the lack of a cup give it away. 2nd image is the correct acquisition.

Not an easy photograph to take, but I did manage to snap this photo of an Ahmed valve with a Xen resting just in the tip of the Ahmed.

My smart friend Sean gives a nice overview of the shortcomings of Goldmann Tonometry.

Behold the splotchy RNFL map of a patient w (usually severe) NPDR. I never hear folks talk about this sign but I use it clinically every day.

Remarkable start to glaucoma day at the Royal Hawaiian Eye Meeting!! Do you use home tonometry?!?!?
