Brief Summary:
This is a multi center, retrospective, chart review study to document the evolution of ocular disease progression in pediatric patients with CLN2.

Condition or disease
Late-infantile Neuronal Ceroid Lipofuscinosis Type 2 (CLN2)

Detailed Description:
CLN2 is a rare disease with limited available ocular natural history data. While current standard of care slows motor degeneration, it is not known to treat the ocular manifestations of disease. This study is planned to document, through retrospective data collection, ocular disease progression in children with a clinical presentation consistent with CLN2. No investigational product is administered in this retrospective, chart review study.

Primary Outcome Measures :
  1. Characterize retinal structural changes in children with CLN2 [ Time Frame: From first available medical chart through informed consent, an average of 10 years ]
    As assessed in by SD-OCT measures in ophthalmic records of children with CLN2


Secondary Outcome Measures :
  1. Characterize changes in visual function. [ Time Frame: From first available medical chart through informed consent, an average of 10 years ]
    As measured by changes in visual acuity over time in ophthalmic records of children with CLN2.
