From: Macular structural integrity estimates are associated with Parkinson’s disease genetic risk
The phenotypic variance explained (R2) by the Parkinson’s disease polygenic risk score for changes in retinal thickness from 20 to 28 years of age. The macular grid of the GCIPL layer is reported. Subfields are described as inferior (I), nasal (N), superior (S), temporal (T), inner (1), and outer (2)
