      Optical Coherence Tomography and Wide-Field Fluorescein Angiography in Retinopathy of Prematurity (Book Chapter)
      The advent and adaptation of many imaging modalities promise to revolutionize our understanding of retinopathy of prematurity (ROP) by improving the detection, diagnosis, and monitoring of response to treatment of this disease. Diagnosis and classification of ROP traditionally relies on an eye exam by an ophthalmologist expert in this area who characterizes extent and character of retinal vascularization via indirect ophthalmoscopy. Many tools now exist that allow for data acquisition ...

      Microscope-Integrated Optical Coherence Tomography Angiography in the Operating Room in Young Children With Retinal Vascular Disease
      Importance Intraoperative optical coherence tomography (OCT) has gained traction as an important adjunct for clinical decision making during vitreoretinal surgery, and OCT angiography (OCTA) has provided novel insights in clinical evaluation of retinal diseases. To date, these two technologies have not been applied in combination to evaluate retinal vascular disease in the operating suite. Objective To conduct microscope-integrated, swept-source OCTA (MIOCTA) in children with retinal vascular disease. Design, Setting, and ...

      Review of intraoperative optical coherence tomography: technology and applications [Invited]
      During microsurgery, en face imaging of the surgical field through the operating microscope limits the surgeons depth perception and visualization of instruments and sub-surface anatomy. Surgical procedures outside microsurgery, such as breast tumor resections, may also benefit from visualization of the sub-surface tissue structures. The widespread clinical adoption of optical coherence tomography (OCT) in ophthalmology and its growing prominence in other fields, such as cancer imaging, has motivated the development ...

    4. One benefit of SD-OCT is the creation of the summed voxel projection [SVP], which is helpful for orientation of individual OCT scans. One can collapse three-dimensional OCT volumes along the depth axis to form a two-dimensional plane, summing pixels to calculate one representative pixel intensity alone each line in the projection.
