Diagnostic Instruments in Optometry

In ophthalmology, diagnosis is the major important part for deciding the treatment for the patients. Only through the proper instrumentation technique, this is achieved. The posterior part of the organ of sight consists of vitreous humour, retina, choroid, and optic nerve. These are viewed using the proper Instruments. Mostly for retinal analysis, optical coherence tomography (OCT) is used. OCT is an imaging technique used for viewing the organ of sight in Two- and Three- Dimensions and for capturing the micrometre resolutions. This is the most important and emerging technologies in the diagnosis because of its easy prediction, Non-invasive technique, less strain and time consumption technique. There are many instruments specially designed for the detection of the organ of sight problems and for the rectification.
