Current Primary Outcome Measures
 (submitted: September 26, 2017)
  • Visual Function [ Time Frame: All assessments available before enrollment ]
    Visual function will include visual examination data from medical records.
  • The National Eye Institute Visual Function Questionnaire (VFQ)-25 [ Time Frame: Enrollment ]
    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) [ Time Frame: Enrollment ]
    The SF-36 surveys health status and quality of life
  • Child Health Questionnaire (CHQ) [ Time Frame: 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)-5L [ Time Frame: Enrollment ]
    The EuroQol-5 Dimension-5 Level (EQ-5D-5L) is a generic HRQoL instrument that is widely used as a PRO measure.

Descriptive Information
Brief Title REALITY LHON Registry
Official Title Observational Registry Study of Leber Hereditary Optic Neuropathy (LHON) Affected Patients
Brief Summary

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.

Study Type Observational [Patient Registry]
Study Design Observational Model: Cohort
Time Perspective: Cross-Sectional

Sampling Method Probability Sample
Study Population

The study will recruit at least 50 affected LHON subjects (both adult and pediatric) from global clinical sites at the following countries, but not limited to: Spain, Italy, France, United Kingdom, and the United States. Efforts will be done to maintain the population of at least 50 affected LHON subjects.

Recruitment efforts of recruiting approximately 75% of eligible subjects with 11778/ND4 mutation and 30% of eligible subjects under the age of 18 at the time of index date, wherever possible, will be done at the study level.
