Ultrasonic diagnosis of retinal detachment in eyes with silicone oil tamponade

Abstract

Objective: To examine the features and values of ultrasonic diagnosis for retinal detachment in eyes with silicone oil tamponade (SOT). Methods: A prospective study. A total of 257 eyes (257 patients) were filled with silicone oil between December 1, 2015 and August 1, 2016 in the Department of Ophthalmology at a hospital in Beijing. All of the patients underwent a color Doppler ultrasound examination in the supine and sitting positions a week prior to surgery. The pre-surgery conditions were compared with the subsequent observations during the surgery to analyze the features and values of ultrasonic diagnosis for retinal detachment in eyes with SOT. Results: Ultrasound manifestations of eyes with SOT included pseudo extension of the ocular axis and an arc-shaped echo between the eye wall and silicone oil. Diagnostic accuracy was 85.6% in the supine position and 93.8% in the sitting position. Conclusion: Ultrasound diagnosis for retinal detachment in eyes with SOT manifests itself in certain patterns. Compared with the traditional ultrasound examination in the supine position, the sitting position examination can be used to further increase the diagnostic accuracy in the ultrasound diagnosis for retinal detachment in eyes with SOT, providing reliable evidence for clinical and differential diagnosis.
