Abstract

Purpose : The purpose of the study is to Identify risk factors for hypotony after silicone oil is removed from the vitreous cavity and to use these risk factors to develop a predictive model for hypotony in this patient population.

Methods : Methods: This was a retrospective, interventional case-series, which evaluated patients at a retinal referral center in the USA. A retrospective review of patients who had surgery from 2000 to 2019 with at least 3 months of followup was performed. Patients who had silicone oil removal were identified from medical records. Logistic regression was used to analyze our data and to identify risk factors predicting hypotony after silicone oil removal.

Results : Review of the records of 5,453 patients was performed to identify our study population. Currently, 109 patients and 121 eyes have been identified with silicone oil removal. Patients included 65 males, 44 females with age range of 27 to 64 years and mean of 52 years. Procedures performed included pars plana vitrectomy with each of the following: 112 tractional retinal detachments, 9 rhegmatogenous retinal detachments and 92 membrane peels. Out of the 121 eyes, 31 developed hypotony one week or longer after silicone oil removal. The logistic regression model, including number of previous pars plana vitrectomies, history of trauma, history of glaucoma, history of steroid response, preoperative intraocular pressure, presence of phakia, age, presence of proliferative vitreoretinopathy, performance of intraoperative retinectomy and axial length showed that only axial length was significantly associated with the development of postoperative transient hypotony (odds ratio = 1.354, P = 0.020).

Conclusions : Patients with a long axial length had an increased odds of developing transient hypotony after silicone oil removal
