No prior preparation is required on the part of the patient for this kind of study, which is entirely painless and has no side effects. The patient was treated medically with hypotensive eyedrops, with significant reduction of intraocular pressure on the left eye, but not enough, evolving to trabeculectomy. Measuring episcleral venous pressure is unpractical, with no commercially-available instruments to this end 3.

COMB Medical license number: In the six patients with unilateral involvement, the IOP was higher in those eyes with dilated conjunctival vessels.

These imaging tests are important because they can exclude other conditions.
