Abstract
Both cataract and vitreous opacity are affected on vision. With ultrasonography “traction”, “contraction”, “organization”, “opacity” of the vitreous is standardized nomenclature in respect of both nature and location, and surgical techniques have been applied as necessary. With 3 degrees of vitreous opacity classification by ultrasonography, a cross- sectional case-control hospital-based study of the relationship of vitreous opacity in two groups: cataract and no cataract, subgroup operated cataract and un-operated cataract are primarily carried out on people who were 50 and over year-old. The relationship of vitreous opacity between un-operated cataract and operated cataract is different in statistics (p<0.05) and the prevalence of vitreous opacity by ultrasonography was confirmed and some results are reported herein.
