Introduction- Macular function can be evaluated electrophysiologically in a steady condition of focal ERG.
Methods- 14 eyes of 14 normal subjects and 24 eyes of 24 patients affected by OAG were examined. All patient undergone Focal ERG and Glaucoma investigation as under the examination format.
Results- OAG patients showed a significant decrease in N1-P1 RADs and an increase in P1 IT in both R1 and R2 with respect to controls. The reduction in N1-P1 RADs was significantly correlated with HFA MD and CPSD. No other significant difference between OAG and controls were found.
Conclusion- OAG patients shows macular dysfunction detectable by the mfERG technique. Since the mfERG N1-P1 component is thought to be generated by preganglionic elements.
