Evaluation of the main methods of diagnostics for detecting the optic nerves atrophy

摘要

Aim of research. To study the specificity and sensitivity, diagnostic efficiency of the different methods of diagnostics at ascending and descending ONA (optic nerves atrophy).Methods. There was carried out an evaluation of sensitivity, specificity and exactness (diagnostic efficiency). There were evaluated the data of examinations of patients who consulted the department of neuroophtalmology of PI “A. P. Romodanov Institute of neurosurgery, NAMS of Ukraine”.Results. There was detected that the maximal indicators of studied parameters at ascending ONA was noticed in HRT (Heidelberg retinal tomography) study. At descending ONA the most resultant parameters were detected in computer perimetry and OEP (optic evoked potentials).Discussions. Diagnostics of ascending and descending ONA has its special features at first stages of atrophic process development. And if diagnostics of ascending ONA is based mainly on the methods of visualization of the head of optic nerve (HRT, OCT) at descending one the more important are OEP and perimetry, methods that define functions of an optic analyzer.Conclusions. There was carried out an analysis of the main methods of diagnostics of ascending and descending forms of ONA. The cited data allow to carry out the more exact and differentiated diagnostics of ONA
