Fig 1.
The pictures compare an EDI-OCT scan where choroidal borders could be reliably identified (A) with another scan with ill-defined choroidal borders (B).
Fig 2.
The graphs show the CT values across different subgroups of age (A), disease duration (B), visual acuity (C), as well as with Fishman phenotype (D), visual field severity stage (E) and ERG alteration grade (F).
Fig 3.
The pictures outline the variability of choroidal thickness in STGD.
A) In this patient a thin choroid was associated with a Fishman phenotype 2, a relatively early onset (15 years) and a longer duration (11 years) of the disease. Visual acuity was 20/400, visual field loss consisted of paracentral scotomas and ERG photopic response was severely abnormal. B) In this patient a thick choroid was associated with a Fishman phenotype 1, a relatively late onset (25 years) and short duration (5 years) of the disease. Visual acuity was 20/200, visual field loss was limited to a central scotoma while ERG shows abnormal photopic response.
