To analyse retinal pigment epithelium (RPE) and neuroretinal (NR) changes on Wide-Field Fundus Autofluorescence (WF-FAF) and Swept-Source Optical Coherence Tomography (SS-OCT) imaging after succesful rhegmatogenous retinal detachment (RD) surgery.
Retrospective, non-interventional study. We analysed the images of 15 patients (8 male, 7 female) who underwent RD surgery. All patients were post-operatively imaged using wide-field colour and fundus autofluorescence (200TX®, Optos plc.) and 1,050nm SS-OCT (Atlantis Deep Range Imaging OCT1®, Topcon Inc.). All images were analysed by two independent observers.
Mean age was 59 years (Range: 26-82). The macula was preoperatively detached in 8 eyes and attached in 7. Eleven patients (73%) underwent 23G pars plana vitrectomy (PPV) surgery with endolaser and intraocular injection of gas; cryotherapy was also used in 6 (55%) of these patients. Four patients (27%) underwent cryobuckle surgery. Post-operative vision improved in all patients. Reported post-operative sympthoms were: metamorphopsia (1) and central blurred vision (8). Macular relative hypo-fluorescence was present postoperatively in 4 patients with pre-operative macula OFF RD and postoperative blurred vision and in 1 patient with pre-operative macular ON and post-operative improvement of vision. Relative macular hyper-autofluorescence was present postoperatively in 9 patients . A pattern of “patchy” relative autofluorescence was present in one eye with postoperative metamorphopsia. SS-OCT showed discontinuation at the junction of the inner and outer sgment of the photoreceptor (IS-OS) line in 7 patients. (SEE TABLE)
Wide-Field Fundus Autofluorescence and Swept-Source OCT imaging following RD surgery can be useful for evaluating RPE function and changes in the neuroretina, thus explaining visual outcome. Further studies are required to look for pre-operative markers of post-operative improvement in vision.
