Purpose

– to study the application of multifocal electroretinography in the detection of functional changes in different macular pathologies.

Setting/Venue

The study included six patients (6 eyes) aged 35-75. years.

Visual acuity fluctuated in the range of 0.02-0.6.

Methods

The study included patients with diabetic macular edema, tractional retinal detachment, subretinal neovascular membrane, central serous chorioretinopathy, Stargardt’s disease, and retinitis pigmentosa.

In addition to standard examinations, the patients underwent multifocal electroretinography (mfERG), color fundus image of the fundus and optical coherence tomography (OCT). During mfERG examination, P1 amplitudes and latencies were measured in concentric rings.

Results

Amplitudes decreased in all patients according to the pathological changes. Correspondence between the degree of pathological change and the amplitude was determined. Except for central serous chorioretinopathy, no significant correlation between latency and amplitude and pathological change was observed in other pathologies.

Conclusions

MfERG is a crucial diagnostic method in the assessment of functional changes in various pathologies of the macula.
