قياس الحساسية الفيزيولوجية للتنبيه الكهربائي (الفسفين) لمرضى الساد

The method of measuring the threshold of the physiological electrical sensitivity (phosphen) in cataract patients through eye electrical stimulating device KNS 2 – 90 (phosphen) is used. The study showed that when the threshold of phosphen electrical sensitivity increases above the normal average (53) microampere in cataract patients before surgical operation - that the eye fundus is unscoped. This refers to the presence of additional illnesses (atrophy of optic nerve papilla, diabetic retinopathy, macular distrophy), and it helps in determining the prognosis of vision after operation and predicting the presence of such illnesses. This way completes other physiological electrical diagnostic methods.
