Standardizatlon of Vitreal inflammatory Activity in Intermediate and Posterior Uveitis

Standardization of observations is recognized as fundamental to clinical research. The methodology for the evaluation of anterior segment inflammatory disease has become well accepted, while the ocular inflammatory standardization of the posterior segment has not been so well described or accepted. A system for the evaluation of vitreal inflammatory activity in patients with intermediate and posterior uveitis is presented. A series of photographs representing various degrees of fundus vitreal haze is depicted. The observer examines the eye with an indirect ophthalmoscope, then chooses the photograph which most closely simulates what is being seen. This technique is rapid and its reproducibility is helpful in standardizing clinical observations.
