“…The value of VEP lies in its ability to identify early problems in the anterior visual pathway, although it is non-specific as to the underlying aetiology and pathology. It is an objective and reproducible test of optic nerve function, and in craniofacial trauma VEPs have been reported as a useful adjunct in early detection of visual loss 30,50 . This complements imaging by determining the functional significance of any structural abnormalities found alongside the optic nerve 18 , and up to 90% of patients with positive VEPs have been reported to make a complete or partial visual recovery 70 .…”

Diabetic retinopathy is one of the common complications of diabetes. Unfortunately, in many cases the patient is not aware of any symptoms until it is too late for effective treatment. Through analysis of evoked potential response of the retina, the optical nerve, and the optical brain center, a way will be paved for early diagnosis of diabetic retinopathy and prognosis during the treatment process. In this paper, we present an artificial-neural-network-based method to classify diabetic retinopathy subjects according to changes in visual evoked potential spectral components and an anatomically realistic computer model of the human eye under normal and retinopathy conditions in a virtual environment using 3D Max Studio and Windows Movie Maker.

Aims: The aim of this study is to evaluate pattern visual evoked potentials as an objective electrophysiological method and to create reference values for Bulgarian population. Methods and Materials: Standardized four-channel equipment ‘Neuro-MEP 4’ produced by ‘Neurosoft’ Company was used. A group of 47 healthy individuals (94 eyes) was studied. The stimulation was monocular, with a contrast-reversing pattern from black to white and vice versa. The investigation was performed with a three-channel recording with equipment adjustments according to the latest published ISCEV standard for pattern visual evoked potentials (2016). Based on a comprehensive overview of the available literature, a protocol of stimulating, amplifying and recording the obtained potentials has been created. The values of pattern visual evoked potential wave components, P50, N75, P100, N145 and P200, were measured. Results: Based on a created protocol, latency and amplitudes of the individual wave components of pattern visual evoked potentials were obtained. The results were statistically processed to create reference values of all pattern visual evoked potentials components, which are used as reference of the laboratory for the Bulgarian population. Conclusion: Pattern visual evoked potentials are objective electrophysiological method which is used to diagnose and monitor numerous ophthalmological and neurological diseases as well as for objective study of visual acuity and visual field in children and aggravation. The creation of pattern visual evoked potentials reference values for the Bulgarian population and its implementation in clinical practice are of particular importance for studying the visual analyser function.
