Completed
Conditions
Leber Hereditary Optic Neuropathy

Other: Patient-reported outcomes (PROs)
Registration Number
NCT03295071
Lead Sponsor

Brief Summary

This study is a multi-country retrospective and cross-sectional observational study of affected LHON subjects, based on retrospective subjects' medical chart abstractions and cross-sectional administration of patient-reported outcomes (PROs).

Detailed Description

The purpose of this study is to understand the evolution of visual functional and structural changes and other associated symptoms in patients with LHON. The relation between genetic, lifestyle and/or environmental factors and the LHON disease will be described, and a better understanding of the natural history of LHON disease and the healthcare associated to with the disease will be sought.

In addition, we would also like to understand the economic burden for patients and their families with LHON resulting from direct and indirect costs they may have because of their disease.

Primary Outcome Measures
NameTimeMethod
Visual FunctionAll assessments available before enrollment

Visual function will include visual examination data from medical records.

The National Eye Institute Visual Function Questionnaire (VFQ)-25Enrollment

The National Eye Institute Visual Function Questionnaire (NEI-VFQ or VFQ)-25 is a valid and reliable 25-item version of the 51-item VFQ.

The 36-Item Short Form Health Survey (SF-36)Enrollment

The SF-36 surveys health status and quality of life

Child Health Questionnaire (CHQ)Enrollment

The CHQ uses the same structure and methodological approach as the SF-36 and is designed and normed for children from 5-to-18 years of age.

EuroQol-5 Dimension (EQ-5D)-5LEnrollment

The EuroQol-5 Dimension-5 Level (EQ-5D-5L) is a generic HRQoL instrument that is widely used as a PRO measure.

Secondary Outcome Measures
NameTimeMethod
Economic burden of diseaseEnrollment

Data will be gathered by questionnaire at cross-sectional survey. Direct costs and indirect costs resulting from LHON will be estimated by all enrolled subjects. Direct costs will include the medical and non-medical direct costs due to LHON
