PURPOSE: Juvenile CLN3 disease, the most prevalent form of Batten disease, is a progressive neurodegenerative disorder resulting from mutations in the CLN3 gene. The objective of this study was to design an ophthalmic rating scale for CLN3 disease in order to quantify disease progression. DESIGN: Retrospective, cross-sectional study. METHODS: Patients underwent ophthalmic evaluations including visual testing, optical coherence tomography and fundus imaging. Patients were also assessed using the Hamburg Juvenile Neuronal Ceroid Lipofuscinosis (JNCL) scoring system. Ophthalmic findings were divided into grades of severity ranging from 0 to 3, and the association between the extent of ocular disease and neurological function and age was assessed. RESULTS: Forty-two eyes of 21 patients were included. The mean age at the time of examination was 13.2 years (range, 5.3-21.9 years). The mean ophthalmic severity grade was 2.4 (range, 0-3). The mean neurological severity score was 9.9 (range, 4-14). Ophthalmic manifestations increased in severity with increasing age of the patients (r = -0.84; P < .001), and a strong correlation was found between the CLN3 ophthalmic rating scale score and the Hamburg JNCL score (r = 0.83; P < .001). CONCLUSIONS: Ophthalmic manifestations of CLN3 disease correlate closely with the severity of neurological symptoms and age of the patient. The newly established Hamburg CLN3 ophthalmic rating scale may serve as an objective marker of ocular disease severity and progression and may be valuable tool for the evaluation of novel therapeutic strategies for CLN3 disease.
