Comparative Assessment of Widefield Fundus Autofluorescence Patterns in Retinoschisis and Retinal Detachment.

This article characterizes widefield fundus autofluorescence (WF-FAF) patterns in retinoschisis (RS), retinal detachment (RD), and combined retinoschisis-detachment (RS/RD), and to correlate them with spectral-domain optical coherence tomography (SD-OCT) findings. A retrospective case series of 13 eyes with senile RS, RD, or RS/RD is presented. One eye underwent imaging of 2 areas within the retina, resulting in 14 data points. Independent, masked graders classified pathology on SD-OCT as RS, RD, or RS/RD and graded WF-FAF images for either hypoautofluorescent areas or mixed autofluorescence (AF) (hyper-AF, iso-AF, hyper-AF with hypo-AF, hyper-AF with iso-AF, or hypo-AF with iso-AF). There was no statistically significant correlation between the autofluorescence pattern and the type of retinal abnormality (P = .74). High variability was found in the characterization of WF-FAF in patients with RS and RD. SD-OCT remains the criterion-standard imaging modality in distinguishing RS from RD in clinically ambiguous cases.
