Gonioscopy with lens haptic (Video)

This gonioscopy video shows an interesting finding: the blue line is a haptic from an intraocular lens that has poked through the iris into the anterior chamber. Fortunately, the eye pressure was not affected, and there does not appear to be any inflammatory response (ie. you don’t see any PAS in this video).

Gonioscopy is difficult to photograph secondary to the magnification and large depth-of-field required. Hopefully, this video demonstrates the stereoscopic appearance of the trabecular meshwork.

Gonio Angle lens
This gonioscopy photo shows a haptic from a three-piece cataract lens that has poked through the iris and is sitting in the iris-cornea angle. The haptic is blue and you can see it in the angle overlaying the trabecular meshwork.
