Prevalence of visual impairment in people aged 75 years and older in Britain: results from the MRC trial of assessment and management of older people in the community. on behalf of the Opthalmic Communications Society, Inc.Įvans JR, Fletcher AE, Wormald RPL, et al. Ultrawidefield fundus images allow high detection and accurate quantification of macular hyperpigmentary changes in intermediate age-related macular degeneration compared with conventional CFP.Ĭopyright © 2020 The Author(s). There was a significant correlation between the presence of hyperpigmentary changes on both CFP and UWF images and hyperreflective foci on structural optical coherence tomography (P < 0.001). The total area of hyperpigmentation measured on UWF images was significantly higher than on CFP images (P < 0.001). At least one hyperpigmentary changes within the standardized grid was detected in 93% using CFP and 100% using UWF camera (P = 0.02). The intragraders and intergraders agreements were high for all measurements (P < 0.001). One hundred eyes of 50 patients had hyperpigmentary changes on funduscopic examination and were included. Structural and en face optical coherence tomography images were correlated with UWF and CFP images to determine spatial correspondence of pigment clumping on fundus images and hyperreflective foci on optical coherence tomography. The overall accuracy to visualize hyperpigmentation and its morphologic features was graded by two independent readers using a standardized grid.

All patients underwent Optos imaging and CFP. This retrospective study included 50 patients diagnosed with intermediate age-related macular degeneration.

To compare pseudocolor Optos ultrawidefield (UWF) retinal images with conventional real-color fundus photography (CFP) for detecting macular hyperpigmentary changes in intermediate age-related macular degeneration.
