Abstract

Abstract: : Purpose: To describe the episodic association of elevated intraocular pressure with the bilateral appearance of blood in Schlemm's Canal. Methods: Clinical case report Results: We describe a case of intermittent spikes in intraocular pressure corresponding to the presence of blood in varying quadrants of schlemm's canal in both eyes (gonioscopic examination performed using the Zeiss goniolens). When the intraocular pressure (IOP) was normalized (with or without medical therapy), no blood was seen in Schlemm's Canal. Whenever blood was seen in Schlemm's Canal, the IOP was elevated. Conclusion: The clinical scenario described does not fit any known cause of blood in Schlemm's Canal. We propose a previously unreported correspondance between a pathologic deep arterial anastamosis and episodic fluctuations in IOP.
