Abstract | ||||
Purpose: to compare between results of multifocal ERG and visual field in cases of primary open angle glaucoma. Methods:30 eyes with primary open angle glaucoma and 30 eyes of normal subjects were included in this study. Humpheray visual (SITA standard 24-2 strategy) and multifocal electroretinography were performed to all included patients and normal subjects. Results:the patients group showed increased latency of the N and P wave of the multifocal ERG when compared to the normal subjects. No difference in amplitude of waves was found between the two studied groups. when comparing different stages of glaucoma (mild, moderate, and severe) according to the mean deviation of the visual field no difference was found in amplitude or latency of the waves produced by the multifocal ERG. Conclusion:multifocal ERG was able to differentiate between patients with POAG and normal subjects in the form of prolonged latency of waves produced, but it was not able to differentiate between different grades of glaucoma. This makes it a good prognostic tool but not a diagnostic tool, where the automated visual field analyzer remains superior in diagnosing POAG. | ||||
