In Vivo Human Retinal Imaging by Optical Coherence Tomography

In the last decade retinal diseases have become prevalently in India and it is growing alarmingly. Fortunately, most of blindness are caused are preventable if treated at appropriate time. Early detection of such retinal diseases like diabetic retinopathy, macular degeneration, retinal detachment and glaucoma is very vital. Optical coherence tomography (OCT) is an In vivo imaging technique for cross sectional imaging of the retinal layers. An Image segmentation algorithm to analyze the thickness of the cross sectional of the retinal layers has been used. The changes in the thickness of the retinal layers in microns scale (10-20 microns) will have a significant impact in the vision if not detected and diagnosed early. The measurement of quantitative thickness of the retinal layer non-invasively using this objective method may facilitate the ophthalmologist to prescribe the diagnosis at the appropriate time that would more likely save the vision of the patient.
