Figure 2. Preoperative, immediate post-surgery and follow-up assessment in a patient with retinal detachment (Case 6) using exo-illumination MIOCT technique.

A: External view showing the position of the endoilluminator and the viewing system; B: the surgeon’s view during the procedure showing the optic disc and surrounding retina being visualised through the viewing system with the external light source and a 3x3 mm scan size cube scan of the MIOCT focused just temporal to the optic disc; C upper image: MIOCT horizontal cross-sectional OCT scan showing retinal detachment and optic disc at one end while; F lower image: the vertical OCT shows superior retinal detachment with attached juxtapapillary inferior retina; D: MIOCT cube scan cross-hair of 8x8 mm scan size centred just above fovea; E upper image: the horizontal cross-sectional OCT scan showing retinal detachment while; E lower image: vertical OCT through fovea shows retinal detachment; F: surgeon’s view showing scleral band and creation of sclerotomy for subretinal fluid drainage; G: MIOCT cube scan cross-hair of 8x8 mm scan size centred just on the fovea; H upper image and lower image: the horizontal and vertical cross-sectional OCT scan showing a reduction in neurosensory detachment height at the end of surgery; I: 3 months post-operative, MIOCT cube scan cross-hair of 4x4 mm size, at the fovea; J upper and lower image: showing attached retina with normal foveal architecture in both horizontal and vertical scan.
