Abstract

Introduction

Vitreous hemorrhage is defined as extravasation of blood into one of the several potential spaces formed within and around the vitreous body¹.  Vitreous hemorrhage can be caused by the pathological mechanisms like disruption of normal retinal vessels, bleeding from diseased retinal vessels or abnormal new vessels, and extension of hemorrhage through the retina from other sources². Vitreous hemorrhage presents clinically as a shower of floaters with blurring of vision. B-scan ultrasound is an important part of ophthalmic diagnosis because of its ability to detect, outline and characterize the nature of soft tissue of eyeball and orbit, regardless the degree of ocular media transparency.

We conducted a prospective study of the underlying causes of dense vitreous hemorrhage. The clinical findings were determined after the vitreous hemorrhage was reabsorbed (after 6 weeks) or following vitreous surgery, and were compared with the B-scan ultrasound findings.
