Abstract

Fundus Perimetry and mfERG with the SLO in Central Serous Retinopathy

Rohrschneider K., Bültmann S.
Heidelberg University, Dept. of Ophthalmology

Purpose: Central serous retinopathy (CSR) leads to impaired visual acuity accompanied by metamorphopsia and a wide variety of subjective impression. We wanted to evaluate the use of fundus perimetry and mfERG in diagnostics and follow-up in patients with CSR.
Method: 12 eyes of 12 patients were examined by automatic static fundus perimetry with Goldmann III targets as well as mfERG using the RETIscan system and the SLO 101 (Rodenstock) for stimulation. Follow-up examinations have been performed in 3 eyes of 3 patients.
Results: Initial visual acuity ranged from 0.2 to 0.8 and recovered to 1.25. Static fundus perimetry showed only minor reduction of threshold values in the area of macular edema in eyes with a history of disease less than 6 months and single occurrence. In these eyes mfERG was normal or only P1 amplitudes were reduced. Five patients with a prolonged history of CSR presented with significant reduction of thresholds as well as P1 reduction combined with signal-loss in mfERG.
Conclusions: Fundus perimetry in combination with mfERG using the SLO appears to be a suitable method for diagnostics and follow-up of CSR. Significantly reduced threshold values in combination with pathologic mfERG signals appear to have a predictive value towards a less favorable outcome while normal or slightly affected mfERG in combination with minimally reduced threshold values seems to go along with restitution.
