Optic disc drusen

Abstract

Purpose: We analyze and discuss the way how we manage the problems in differential diagnosis emerging from the occurence of optica disc druses with the advent of the new imaging technique of computerized tomography, ultrasonography and fluorescein angiography. Patients and metohods: We present three patients with optic disc drusen. The first patient is 48 years old female presenting with episodes of transient amaurosis but with enough fundus findings to set the suspicions of optic disk drusen. The other two cases are pediatric patients who were hospitalized for arthritis and fever of unknown origin, and in which routine fundoscopic examination reveled unilateral oedema of the optic disc. Fluorescein angiography, CT scan and B ultrasonography was done in all the the above patients. Results and conclusion: Deep sited optic disk drusen are often a problem in the differential diagnosis of the optic disc edema. THe newest imaging techniques of CT-scan and B-ultrasonography are valuable tools in solving the problem.
