Abstract

Purpose: To describe clinical and para-clinical features of silicone sponge rejection after retinal detachment surgery. Materials and methods: The study was conducted on a data file of 21 patients (22 eyes) who were diagnosed with silicone sponge rejection. Results: Silicone extrusion registered the highest number with ten eyes (45.5%). The figures for eyes with pain and infection were six (27.3%) and four (18.2%). However, there was only one eye with erosion and intrusion; one eye with another cause (the fellow eye had erosion and intrusion before), and no eyes with anterior ischemic signs. In terms of the silicone removal time: only one case (5.0%) was classified early and required removal of the sponge within the first eight weeks following surgery, while twenty-one cases (95.0%) required sponge removal between five months and twenty years following surgery. In addition, the number of silicone sponges with non-blood staining was the highest, at 17 (77.3%). The figure for the sponge with blood staining was lower, at 5 (22.7%). After silicone sponge removal, two cases (9.1%) were recognized as retinal redetachment. Conclusion: Retinal detachment surgery with a silicone sponge has now been more and more prevalent due to its high effectiveness and success. Although silicone sponge rejection is at a quite low risk, it may also contribute to a number of severe consequences if left permanently. Silicone extrusion constitutes the highest figure in patients with silicone sponge rejection. Thus, regular follow-up and early detection of signs of silicone sponge rejection play a pivotal role in not only reducing the severe consequences but also attaining the anatomic function of the retina
