Exclusion Criteria:
Multifocal Electroretinogram Amplitudes
Amplitude at first annular ring at multifocal electroretinogram RETIscan (Roland Consult, Wiesbaden, Germany) is used for multifocal retinogram. The recording protocol was chosen according to the International Society for Clinical Electro-physiology of Vision (ISCEV) guidelines.
Time frame: baseline, 1 month, 3 months, 6 months
Best Corrected Visual Acuity
Best-corrected visual acuities were obtained with Snellen charts. Snellen's visual acuity was converted logarithm of the minimum angle of resolution (logMAR) for statistical analysis.
Time frame: baseline, 1 month, 3 months, 6 months
