Inclusion criteria
Inclusion criteria: 1) clinically diagnosed as RPE impaired disease on the diagnostic criteria 2) 20 years of age or older 3) Window defect is observed by FAG. 4) collected visual acuity is less than 0.3 or less, or visual field measured with Goldman dynamic quantitative visual field (target: V-4) is within 20 degrees, or Estherman static quantitative visual field is 70 points or less. 5) Capable of understanding the documents of the research context and of informed consent and is able to provide a written informed consent
