Abstract
PURPOSE
To compare optical coherence tomography measurements; central macular thickness, ganglion cell complex, and retinal nerve fiber layer thickness in patients with epilepsy versus healthy controls.
METHODS
We evaluated 28 eyes of 28 patients with epilepsy and 34 eyes of 34 healthy subjects. Central macular thickness, ganglion cell complex, and retinal nerve fiber layer thickness measurements were performed by spectral-domain optical coherence tomography.
RESULTS
Superior and superotemporal quadrant ganglion cell complex, average, and superior quadrant retinal nerve fiber layer thickness measurements were significantly lower in epilepsy group compared to healthy control subjects. Central macular thickness was significantly lower in polytherapy group compared to monotherapy group. Ganglion cell complex and retinal nerve fiber layer thickness measurements were not significantly different between polytherapy and monotherapy groups.
CONCLUSION
The present study shows that epileptic patients taking antiepileptic drugs have reduced ganglion cell complex and retinal nerve fiber layer thickness compared to healthy controls. This can be related to the epileptic process in the brain. Optical coherence tomography may be a useful tool for showing the neurodegeneration in patients with epilepsy.
