Imaging Studies

A-mode ultrasound is used to measure axial length.

B-mode ultrasound can discover occult choroidal effusions or hemorrhages or vitreous hemorrhage.

Ultrasound biomicroscopy (UBM) is used to obtain cross-sectional images of the anterior segment, cornea, iris, lens, and ciliary body at 25-50 µm resolution with a tissue penetration of 5 mm. UBM can help to differentiate the anatomic mechanisms responsible for different forms of glaucoma. [18]

OCT anterior segment imaging may be used to evaluate anterior chamber depth and corneal thickness. [19] Structures behind the iris are not clearly seen because the iris pigment epithelium acts as a barrier to the OCT laser beam.

Other Tests

The Seidel Test is used to evaluate the existence of anterior chamber leakage in the cornea.

Electronic indentation tonometry, such as the Tono-Pen (Reichert, Inc) or AccuPen (Accutome, Inc), can be used to measure intraocular pressure.

Procedures

Bleb or wound leaks should be identified and treated first.

Because of its simplicity, a new laser iridotomy should be performed if suspicion of pupillary block exists.
