Optical Coherence Tomography (OCT) enables high–resolution cross sectional images of the retina. The recent OCT/SLO presents a combined OCT and Confocal Scanning Ophthalmoscope, acquiring images either as longitudinal sections (B–scan ) or as a parallel section (C scan). The aim of our study was to compare OCT 3 and OCT /SLO in the visualization of the Epiretinal Membranes (EM).
: 30 consecutive patients (30 eyes) ( mean age 50 ±17 years), with idiopathic and secondary EM diagnosed by ophtalmoscope examination were submitted to OCT3 and OCT/SLO before surgical procedure. The different morphological aspects of the retina were recorded.
Both the instruments permit a correct diagnosis of EM . The principal differences between the two instruments were the following: using OCT/SLO we obtained 1) a better visualization of retinal contractions 2) a better visualization of the retina and vitreous relationship 3) a complete representation of EM extension 4 ) a better localization of the strongest traction of EM .
We believe that OCT/SLO, using its ability to overlap the retina simultaneously, may help the vitreo– retinal surgeon to find the best clivage plane where to pick up and peel the membrane overlaying the retina.
