[Diagnostic and therapeutic value of the panfundoscope in diseases of the posterior eye segment].

The scope of this work is to evaluate the diagnostic and therapeutic value of using Schlegel's panfundoscope with respect to the three mirror lens on the basis of a double-blind comparative study. This method is especially rewarding for the follow-up of fundus lesions, their detection through opaque media and/or a poorly dilated pupil, as well as through an intraocular lens. Panretinal photocoagulation, prophylactic annular photocoagulation of peripheral retina and vitrectomy can be performed more easily through this lay-out.
