Vitreous opacities, also known as floaters, are a common phenomenon in most people’s lives. For those who suffer from a severe amount of these floaters, laser vitreolysis is one treatment option. There is however a significant risk of the laser being misguided into critical areas near the retina or lens due to the manual nature of the procedure. Moreover, the current procedure lacks an online success control. To enhance the safety for the patient and simplify the handling for the physician we introduce a method to visualize and segment vitreous opacities via optical coherence tomography for an improved computer-guided procedure.
