Abstract: Purpose: To evaluate the role and sensitivity of multifocal electroretinogram in patients with retinitis pigmentosa (RP). Subjects and Method:The study included 75 subjects (150 eyes); 25 subjects (50 eyes) were normal, 25 patients (50 eyes) suffered from retinitis pigmentosa without macular edema; 25 retintis pigmentosa patients (50 eyes) with macular edema.All patients underwent full ophthalmological examination, full field electroretinogram (ERG) and multifocal electroretinogram (MF-ERG).MFERG is repeated twice in the same day and in the next day.Results: The amplitudes of P1in all rings were reduced in retinitis pigmentosa compared with normal .The amplitude of P1 was reduced in ring 1,2,3 more with RP associated with macular adema compared with patients without macular edema.There were delay in rings4,5 only in RP without macular edema compared with normal, Whereas there were delay in all rings in retintis pigmentosa associated with edema.Conclusion: MFERG is simple easy objective tool valuable for evaluating the macula in RP
