Question 77

You're seeing a 64 year old female due to acute intraocular pressure (IOP) elevation OU that was noted by an outside optometrist. The IOP was 56 mmHg OD and 52 mmHg OS. She was started on timolol, latanoprost, and prednisolone gtts OU and referred to you (the expert!). Her IOP today in clinic is 18 mmHg OD and 16 mmHg OS. Pachymetry is normal, there are no keratic precipitates, the anterior chamber is quiet, cup to disc ratio is 0.4 OU. She is pseudophakic OU and vision is 20/25 OU. There is no retinal detachment. You deftly perform gonioscopy which shows gray precipitates in the trabecular meshwork of both eyes. Otherwise the angles are open and deep with no vessels crossing the angle. What is the most likely diagnosis?
