Evaluation of En Face optical coherence tomography in the assessment of vitreoretinal interface disorders

Purpose The aim of this study was to assess the clinical value of En Face optical coherence tomography (OCT) in vitreoretinal (VR) interface disorders and how can we benefit from it when combined with B-scan OCT. Patients and methods This cross-sectional study included 20 eyes of 18 patients having VR interface disorders who attended Kasr El-Ainy Ophthalmology Outpatient Clinic during the period from January to December 2015. All patients were subjected to full ophthalmological examination followed by SD-OCT imaging using Optovue Rtvue machine. Results In this study, 20 eyes of 18 patients, including 10 females and eight males, were examined. Age ranged from 20 to 60 years. Unilateral pathology was present in 16 cases and bilateral pathology in two cases. Of the 20 eyes, eight had epiretinal membrane, four had full-thickness macular holes (one atrophic and three traumatic), and two had lamellar macular holes. En Face C-scan images when combined with B-scan images gave three-dimensional view of the retinal segment from superficial to deep as well as cross-sectional view allowing better diagnosis and management of the VR interface disorder. Conclusion En Face OCT can detect epicenters in epiretinal membranes and can detect full-thickness and lamellar macular holes. C-scan images are very useful when combined with B-scan images in viewing VR interface disorders.
