[Clinical effectiveness of bio-micro-ophthalmoscopy using aspherical high-diopter lenses]
Abstract:
The author presents an optimized method of bio-ophthalmoscopy using new Russian aspherical high-diopter lenses +60.0, +75.0, and +90.0 diopters, supplied with photoprotective filters. Excellent characteristics of the lenses ensure a perfect stereoscopic picture of a large site of the fundus oculi and of the intraocular cavity making use of slit lamps of any design. Various chorioretinal abnormalities, including the very initial changes, are easily diagnosed. The method is rather simple and ergonomic. An appreciable advantage of high-diopter aspherical lenses is the possibility of using them in coagulative contact-free laser interventions on the fundus oculi, which may be performed, primarily, in cases with peripheral abnormalities which are difficult to examine using the traditional Goldman's type lenses. Methods of working with the new optical elements are described in brief and recommendations on their practical use are offered.
