Abstract

Background and objective: To evaluate the clinical characteristics of discrete margins of different retinal reflectivity (DMDRR) in ultra-widefield fundus photography.

Patients and methods: This DMDRR comprises a discrete border, with differing patterns of reflectivity on either side. Spectral-domain optical coherence tomography was performed on both the macula and the margin. The incidences of epiretinal membrane (ERM) and peripheral retinal pathologies of patients with a DMDRR (n = 36) were compared with a control group (n = 41).

Results: An ellipsoid zone (EZ) defect at the DMDRR was detected in 34 eyes (92.2%), and vitreous traction was detected in 20 eyes (55.6%). A significantly higher proportion of eyes in the DMDRR group had an ERM, retinal hole, and cystic retinal tuft compared with the control group (P = .022, P = .010, and P < .001, respectively).

Conclusions: The DMDRR indicates EZ disruption that may originate from vitreous traction. Meticulous observation for vitreoretinal interface diseases is mandatory for these patients. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:273-280.].
