| Research Abstract |
We developed the world's first three-dimensional optical coherence tomography (OCT) which enables non-invasive stereoscopic observation of the inner structures of the anterior eye segment. We have started clinical application of this instrument as the fastest anterior segment OCT with ability to perform minute examination of the ocular tissue with deeper penetration. Non-contact investigations were conducted in areas such as qualitative and quantitative analysis of the anterior chamber angle, observation of the inner structure of the conjunctival bleb after glaucoma filtering surgery, quantitative analysis of anterior chamber depth and volume parameters, and assessment of corneal topography.
