Abstract
Purpose: Multimodal imaging has not been documented for CABP4-related retinopathy. In this study, we describe optical coherence tomography (OCT) and fundus autofluorescence findings for five genetically confirmed cases. Methods: Retrospective case series. Results: Four patients with the previously described homozygous Saudi CABP4 founder mutation c.81_82insA (p.Pro28ThrfsX44) and one patient with the homozygous mutation c.1A>G (p.Met1?) in CABP4 were examined. The ages ranged between 9 and 16 years at last follow-up, and the duration of follow-up ranged from 2 to 12 years. Foveal thickness was reduced ranging between 175 and 212 micrometers. Wide field imaging including fundus autofluorescence was unremarkable. All patients presented with a negative electroretinogram, with a variable amount of cone and rod dysfunction. Over follow-up, there was no electroretinographic indication of any progressive retinal dysfunction. Conclusions: Foveal thinning is a feature of CABP4 retinopathy. Normal autofluorescence is consistent with inner retinal dysfunction and suggests the condition could be amenable to gene therapy. Retinal dysfunction was stable throughout follow-up.
