Abstract

Purpose : Juvenile CLN3 disease (Batten disease) is associated with progressive cerebral neurodegeneration of the retina and central nervous system, leading to rapid visual deterioration and subsequent neurological deterioation. We obtained SD-OCT based quantitative data on the progression of retinal thickness reduction, as well as the potential clinical relevance of ophthalmic imaging as a parameter of global neurodegeneration over time.

Methods : Analysis of retinal thickness in 15 patients with juvenile CLN3 disease as well as an age-matched control group was obtained by measuring 3 mm temporal and nasal of the fovea with the aid of SD-OCT and compared to an age matched control group. Further age-dependent subanalysis of the inner retinal layer (retinal nerve fiber layer - inner plexiform layer) and the outer retinal layer (inner nuclear layer - retinal pigment epithelium) was performed. Subsequently age-matched cortical grey substance MRI-volumetry was correlated with the obtained retinal thickness measurements.

Results : In patients with juvenile CLN3 disease mean nasal retinal thickness ( 255.67 μm ± 30.99 μm) as well as temporal retinal thickness (219,65 μm ± 27.82 μm) were significantly reduced compared to the age-matched control group (p ≤ 0.01). The mean nasal inner retinal thickness was 141.42 μm (± 18.70 μm), wereas the temporal inner retinal thickness was 123.27 μm (± 19.60 μm). Nasal outer retinal thickness was 105.88 (± 19.89 μm); the mean temporal outer retinal thickness was 96.57 μm (± 9.23 μm). Furthermore correlation of total cumulative nasal and temporal retinal thickness with cortical grey substance MRI-volumetry showed a strong correlation. ( r = 0.807; r2 = 0.651)

Conclusions : The presented study presents novel insight into the age-dependent retinal degeneration in patients with juvenile CLN3 disease. As continuous retinal degeneration can be non-invasively obtained by SD-OCT imaging and correlates well with cortical grey substance reduction, ophthalmic retinal imaging might become a valuable tool to assess global neurodegenerative progress in juvenile CLN3 disease and might establish as an outcome parameter of future therapeutic trials.
