Predominantly Superior Retinal Tears Detected by B-Scan Ultrasonography.
INTRODUCTION: When fundus examination is not possible, ultrasonography (US) is an accurate tool for the diagnosis of retinal tears (RT). The aim of this study was to describe the predominant location of RT, the factors influencing their location, and the vitreous status of eyes with RT using US.
METHODS: A prospective study was conducted in all patients diagnosed with RT by B-scan US (Aviso, Quantel Médical, Clermont-Ferrand, France). The primary endpoint was to assess RT preferential location using US. Secondary endpoints were the rate of posterior vitreous detachment (PVD), number of eyes with multiple RT, and axial length (AL).
RESULTS: A total of 101 eyes of 100 patients with RT were included. RT main location was in the superior quadrants (either nasal superior, strictly superior, or temporal superior) in 71% of cases. All patients were diagnosed with PVD by US, and 79% had a vitreous hemorrhage. Twelve eyes (13%) were diagnosed with multiple RT. The mean AL was 24.62 ± 2 mm, and it was significantly longer in eyes without superior RT (25.52 mm versus 24.37 mm; p =0.004).
CONCLUSION: In this study, we showed a superior location of RT diagnosed by US in more than two-thirds of cases associated with a significantly shorter AL than in other locations. This finding could increase US sensitivity for RT detection and help to improve the US learning curve of ophthalmologists in training and surgical decision-making when the retina is inaccessible due to opacity media.
