Abstract
Purpose: :
Detections of the micro retinal tears in the posterior staphyloma are frequently difficult works. We evaluate the ability of three-dimensional optical coherence tomography (OCT) for the detection of the micro retinal tears in the posterior staphyloma.
Methods: :
We prospectively examined 3 eyes of 3 patients with the rhegmatogenous retinal detachments in the highly myopic eyes with the posterior staphylomas. In all eyes, the retinal tears could be hardly detected with the conventional fundus examinations. Three-dimensional OCT data sets were obtained using commercialized spectral domain OCT (Topcon 3D -1000, center wavelength 840 nm, 18000 Ascan/sec). We evaluate the areas with retinal detachments using the series of B-scan OCT images.
Results: :
The micro retinal tears could be easily detected using the series of B-scan OCT images. The micro retinal tears were existed adjacent to the retinal vessel or small chorioretinal strophy. Three-dimensional structures of the posterior hyaloid membranes and detached reitnas could be clearly detected, and the traction at the micro retinal tears could be also confirmed. The locations of the retinal tears were registered in the color fundus photography images, and compared with the findings in vitrectomy. The location of retinal tears corresponded well with the findings during vitrectomy.
Conclusions: :
Three-dimensional OCT is an effective tool to detect the micro retina tears, and useful for the vitrectomy for the rhegmatogenous retinal detachment in the area with posterior staphyloma
