Slit-lamp photographs of the right (A) and left (B) eye demonstrating moderate peripheral and central anterior chamber shallowing after recent ingestion of methazolamide. High-frequency (35 MHz) ultrasound biomicroscopy reveals anterior displacement of the lens-iris diaphragm due to ciliary body edema and supraciliary effusion (arrows) in the right (C) and left (D) eye. Anterior chamber depth measured 1.2 mm in each eye and lens thickness measured 4.8 mm and 4.9 mm in the right and left eye, respectively. B-scan ultrasonography revealed shallow posterior choroidal effusions (arrows) in the right (E) and left (F) eye.

Haag-Streit USA, Mason, OH, USA) revealed marked conjunctival chemosis, mild microcystic corneal edema, and shallow anterior chamber in each eye (Figure 1A and B). High-frequency (35 MHz) ultrasound biomicroscopy (UBM; Model P60, Paradigm Medical Industries, Salt Lake City, UT, USA) confirmed shallow anterior chambers and also revealed anterior displacement of the lens-iris diaphragm associated with ciliary body edema and a prominent ciliochoroidal effusion in each eye (Figure 1C and D). Posterior B-scan ultrasonography (Eye Cubed, Ellex, Inc., Minneapolis, MN, USA) revealed posterior choroidal effusions (Figure 1E and F).
Slit-lamp photographs of the right (A) and left (B) eye demonstrating relative deepening of the anterior chambers after discontinuation of methazolamide. High-frequency (35 MHz) ultrasound biomicroscopy reveals resolution of ciliary body edema and supraciliary effusion in the right eye (C) and near complete resolution (arrow) in the left eye (D). Anterior chamber depth measured 2.7 mm and 2.3 mm in the right and left eye, respectively. Lens thickness measured 4.7 mm and 4.9 mm in the right and left eye, respectively. B-scan ultrasonography reveals complete resolution of the posterior choroidal effusion in the right eye (E) and a small persistent effusion (arrow) in the left eye (F).

Slit-lamp examination revealed deepening of each anterior chamber (Figure 2A and B) and high-frequency UBM revealed posterior displacement of the lens-iris diaphragm with normal ciliary body architecture (Figure 2C and D). Posterior B-scan ultrasonography also revealed complete resolution of the posterior choroidal effusion in the right eye with a small choroidal effusion noted in the left eye (Figure 2E and F).
