Description
Summary:Background To report emulsified particles and related complications after removal of silicone oil (SO) by spectral domain-optical coherence tomography (SD-OCT) and fluorescein angiography (FA). Methods A prospective, single-center investigation was performed using SD-OCT, FA and flare cell photometry measurements to evaluate in a cohort of eyes with emulsified silicone particles after removal of long-term SO tamponade. Results Nineteen eyes of the 19 patients with emulsified silicone particles detected in ophthalmoscopic exam were included in the study: 13 (68%) were male, and 6 (31.6%) were female, and their mean age was 52.75 ± 16.06 years. Preoperative diagnoses were rhegmatogenous retinal detachment in all eyes. The mean duration of the silicone oil’s presence in the eye was found as 12.63 ± 4.87 (7–26) months. SD-OCT examination postoperatively showed small, round and hyper-reflective structures compatible with emulsified silicone particles on preretinal surface in 7 (36.8%) eyes, intraretinally in 6 (31.6%) eyes and in the vitreous in 12 (63%) eyes. FA imaging demonstrated pearl-like hyper-fluorescence at early and late phases on the large blood vessels in 9 (47.4%) eyes. Late phase hyper-fluorescence due to leakage on the macula was observed in 17 (89.5%) eyes. Diffuse peripheral leakage and hyper-fluorescence was detected in 11 (57.9%) eyes. Flare levels were higher in eyes with emulsified SO compared to unaffected fellow eyes ( p
