Purpose: To objectively investigate retinal function using multifocal electroretinography in patients with choroidal hemangioma undergoing treatment with photodynamic therapy using verteporfin (PDT).
Method: 8 eyes of 8 patients with vision loss due to subfoveal exudation related to choroidal hemangioma underwent photodynamic therapy (light dose of 100 J/m² at 692 nm). Pre- and postinterventional conduction of 103 focal ERGs in the central 25° was performed using the VERIS multifocal electroretinography system (mfERG, EDI, California). Follow-up examinations were performed after 60–82 months.
Results: Central amplitudes of N1 and P1 mfERG responses revealed early increases with shortened implicit times corresponding to fluid resorption and vision gain after PDT.
Conclusion: mfERG long-term follow-up reveals sustainment after early improvement of retinal function and further underlines PDT efficacy and safety in patients with symptomatic circumscribed choroidal hemangioma.
