Electrooculogram (EOG) findings in a case of acute exudative polymorphous vitelliform maculopathy (AEPVM) detected following trauma

Purpose The purpose of this study was to monitor a case of acute exudative polymorphous vitelliform maculopathy detected following trauma. Methods Clinical examination included fundus photographs, optical coherence tomography (OCT) and fluorescein angiography. Pattern and full-field electroretinograms (PERG; ERG) and serial electrooculograms (EOG) were performed, incorporating the international standards. Results A 45-year-old Caucasian woman developed blurring of vision in both eyes 5 days after a serious road traffic accident. On examination, bilateral serous macular detachments and multiple small yellow subretinal lesions were observed in both eyes associated with areas of serous retinal detachment superior and inferior to the yellow lesions in the left eye. OCT showed retinal elevation with a band of high reflectance on the outer retina but no intra-retinal fluid or elevation of the retinal pigment epithelium (RPE). There was bilateral EOG reduction in keeping with generalised RPE dysfunction and pattern ERG evidence of left macular involvement. After 9 months, the patient reported spontaneous improvement in vision with gravitational settling and coalescence of the subretinal yellow deposits. At 37 months, there was improvement in the EOG and visual acuity. Conclusions A rare case of AEPVM is described that was detected following trauma and which gradually improved over 37 months. The EOG showed evidence of generalised RPE dysfunction that resolved and may be useful in the monitoring of AEPVM.
