INTRODUCTION Pseudo-Foster Kennedy syndrome is a triad consisting of ipsilateral optic atrophy, contralateral optic disc edema, and ipsilateral anosmia in the absence of an intracranial mass. Vitamin B12 plays an important role in DNA synthesis, and its deficiency causes peripheral neuropathy, myeloneuropathy, and, very rarely, optic neuropathy. CASE PRESENTATION In this study, we describe a ...

Випадки синусогенних пошкоджень зорового нерву складно піддаються статистичній обробці в силу різноманітності проявів початковий період та відмінностей перебігу, що не дає можливості своєчасно встановити діагноз, а також стандартизувати лікування.
 Мета дослідження полягала у вивченні ознак атрофії нерву, спричиненої вторинними невритами, поєднані з синуситами за допомогою оптико-когерентн...

Normative data were obtained in 52 volunteers to both transient and steady-state checkerboard pattern reversal. Two sizes of checks subtending 15' and 31' of visual angle were used. The simultaneous recording of pattern ERGs (P-ERGs) and visual evoked potentials (VEPs) permitted the determination of the retinocortical time. That is, the transit time expressed in milliseconds between the activat...
