Optical Coherence Tomography (OCT) images were taken using Cirrus HD-OCT (Carl Zeiss Meditec) with 5 line raster and high-definition 5 line raster modes. Images with signal strength weaker than 5/10 were excluded. Distinction of COST line and the integrity of COST line, external limiting membrane, and the photoreceptor inner segment and outer segment junction at the fovea were recorded. Demographic data, refractive error of the eyes, signal strengths of the OCT images were acquired for analysis.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '20 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Thirty-seven eyes of 37 individuals without eye diseases', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* individuals without eye diseases\n\nExclusion Criteria:\n\n* individuals with eye diseases'}, 'identificationModule': {'nctId': 'NCT01316003', 'briefTitle': 'Distinction of Cone Outer Segment Tips by Spectral-Domain Optical Coherence Tomography in Normal Eyes', 'organization': {'class': 'OTHER', 'fullName': 'Kyorin University'}, 'officialTitle': 'Distinction of Cone Outer Segment Tips by Spectral-Domain Optical Coherence Tomography in Normal Eyes', 'orgStudyIdInfo': {'id': 'KyorinEye004'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Normal subjects', 'description': 'Thirty-seven eyes of 37 individuals without eye diseases', 'interventionNames': ['Other: Optical coherence tomography']}], 'interventions': [{'name': 'Optical coherence tomography', 'type': 'OTHER', 'otherNames': ['Cirrus HD-OCT (Carl Zeiss Meditec)'], 'description': 'Optical coherence tomography', 'armGroupLabels': ['Normal subjects']}]}, 'contactsLocationsModule': {'locations': [{'zip': '181-8611', 'city': 'Mitaka', 'state': 'Tokyo', 'country': 'Japan', 'facility': 'Kyorin Eye Center', 'geoPoint': {'lat': 35.68361, 'lon': 139.56002}}], 'overallOfficials': [{'name': 'Makoto Inoue, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Kyorin Eye Center'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Kyorin University', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Associate professor', 'investigatorFullName': 'Makoto Inoue', 'investigatorAffiliation': 'Kyorin University'}}}}
