Massive Silicone Oil Migration into the Subconjunctival Space: A Leakage Mechanism Dilemma
Téllez J; Vela JI; Luna S; Delgado RCase Reports in Ophthalmology 2018; 9: 310-314
PURPOSE: To report a case in which an early, massive silicone oil migration into the subconjunctival space occurred in a patient after sutureless vitrectomy with the presence of a previously implanted pars plana glaucoma drainage device. CASE REPORT: An 80-year-old man presented with neovascular glaucoma secondary to a proliferative diabetic retinopathy in his left eye. After an intracamerular bevacizumab injection and panretinal photocoagulation, a 23-gauge pars plana vitrectomy (PPV) combined with a superotemporal Ahmed pars plana glaucoma valve implantation was performed. Afterwards, the patient underwent a new 23-gauge PPV for a dense vitreous hemorrhage. Intravitreal 1,000 centistokes silicone oil was placed to prevent recurrent intraocular bleeding. No sutures were performed. In the first postoperative month, a massive migration of silicone oil into the 360° subconjunctival space was noted until no intraocular silicone oil was observed. CONCLUSIONS: We discuss the possible leakage mechanisms in this particular case.
