To describe multimodal imaging findings using spectral domain optical coherence tomography (SD-OCT), near-infrared and short-wave fundus autofluorescence (NIR-FAF and SW-FAF) in eyes with rhegmatogenous retinal detachment treated with vitrectomy and gas or silicone oil tamponade and evaluate presence or signs of sticky silicon oil phenomenon.
Prospective case series.
We studied 78 consecutive patients affected by rhegmatogenous retinal detachment underwent 3-port pars plana vitrectomy with gas or silicone oil tamponade from January 2010 to September 2013. Ophthalmologic examination, SD-OCT and FAF were performed before (when the anatomical situation made it possible) and after surgery (always). SD-OCT analysis was performed by mean of Spectralis-OCT Blue Peack (Heidelberg Engineering, Germany) and NIR-FAF / SW-FAF was analysed with spectralis HRA (Heidelberg Engineering, Germany). In vitro Autofluorescence analysis was carried out also to all the liquid substances used.
Presence of silicon oil in camera vitrea creates an image of ‘‘level’’ on the OCT and masks physiologic autofluoresence and reflectivity with a blurred image. Epiretinal sticky oil gives hiper reflective spots that are hyper autofluorescent in NIR and SW-FAF. Cases with complete retinal detachment underwent to multiple tamponades present hyper autofluorescent spots in NIR-AF that was associated with chronic retinal edema.
SD-OCT and FAF can be usefull to reveal intravitreal or epiretinal presence of tamponades. Hyperautofluorescence in NIR-AF can be associated with presence of tamponades under the retina that causes chronic inflammation of the retina associated with macular edema. Multimodal retina imaging can be useful to evaluate presence of the sticky oil phenomenon and consequent inflammation.
