Abstract Details


To determine how the magnitude of myopia influences the visual field as measured by multifocal visual evoked potential (M-VEP).


Ophthalmology Departments, Mansoura University and Benha University Hospitals, Egypt.


The study included 180 eyes of normal and myopic volunteers with best corrected visual acuity (BCVA) of 6/6 or better. The subjects were divided into four groups: emmetropia with refractive error of ±0.25diopter (D), low myopia of -0.25D to -4.00D, moderate myopia of-4.25D to -8.00D, and high myopia of >-8.00D (45, 44, 48, 43 eyes , respectively). All subjects were tested by M-VEP to determine positive peak wave (p) amplitude and latency, and by static automated perimetry (SAP) to determine mean deviation (MD) and corrected pattern standard deviation (CPSD).


In high myopic group 4, there were statistically significant correlations between mean M-VEP amplitude and both spherical equivalent for myopia (R=0.52, P=0.001), and with MD of SAP (R=0.6, P=0.00). M-VEP latencies showed prolongations only in group 4 (not significant). While M-VEP P wave amplitude and latency in mild and moderate myopia were similar to emmetropia.


High myopia could alter the visual field obtained by M-VEP , while low and moderate myopia do not alter the M-VEP parameters.
