Our lab and others have shown that the ganglion cell complex (GCC) - the sum of the retinal nerve fiber, ganglion cell and inner plexiform layers - is reduced in patients affected with Leber’s Hereditary Optic Neuropathy [Balducci, 2015, and Akiyama, 2013]. The purpose of this study was to determine if this finding is consistent in all patients affected by mitochondrial optic neuropathies (MON).
A retrospective chart review was conducted to identify all patients with mitochondrial optic neuropathies who presented to our clinic over a 1-year period and had both a central scotoma demonstrated on visual field and who had undergone a macular cube scan for GCC analysis (HD-OCT (Zeiss Meditech)). Forty-five subjects affected with LHON (n1=41) or dominant optic atrophy (n2=4) were identified.
All patients affected with a MON had a reduction in the GCC layer in all quadrants of greater than 2 standard deviations when compared to age-matched controls. The average GCC thickness was 59.5±19.9µm. There was no significant difference between quadrants. Both LHON and DOA patients showed a similar decrease in GCC thickness.
The pattern of GCC loss and RNFL thinning appears to be a consistent finding in MON. This suggests that GCC may be a useful metric for patients with MON, particularly if used in conjunction with retinal nerve fiber layer thickness.
