Abstract
PURPOSE
To observe the shape of posterior vitreous spaces using swept-source optical coherence tomography (SS-OCT) in normal eyes. METHODS: The posterior vitreous of 80 eyes of 80 volunteers without ocular disease was imaged. The DRI OCT-1 Atlantis (Topcon, Oakland, NJ, USA) was used to acquire scans of the posterior vitreous over an 18 × 18-mm2 area using the 12-mm horizontal line scan protocol. The size of the premacularis bursa was measured by the aliper function of the OCT. RESULTS: A boat-shape bursa was found in most cases. The prevalence of detected bursa fell with further increases in the extent of posterior vitreous detachment. The mean width of the bursa premacularis was 7,679.1 µm and the mean depth was 471.4 µm. CONCLUSIONS: Deep range imaging optical coherence tomography will provide improvement for in vivo anatomic characterization of the cortical vitreous, and allow better visualization of the dimensions of the bursa premacularis.
