The Therapeutic Effect of Combination of Orbital Decompression Surgery and Methylprednisolone Pulse Therapy on Patients with Bilateral Dysthyroid Optic Neuropathy

Figure 3

Visual evoked potentials (VEP) testing showed latencies and amplitudes before and after orbital decompression on the left eye combined with methylprednisolone pulse therapy (MPT). (a) Prolonged latencies and reduced amplitudes were shown in both eyes before orbital decompression on the left eye combined with MPT. (b) Latencies and amplitudes restored in operated eyes after orbital decompression on the left eye combined with MPT.
