Abstract: There are currently detailed information on the retina because there in Optical Coherence Tomography (OCT), Nevertheless, use more in OCT depends on the qualitative analysis of the data. Although technological advances have provided a lot of time and effort in reaching speed data, the OCT did not reach for the full methods for image analysis, and thus there is an urgent need analytical tool for images that allow for the OCT to achieve its full potential as a diagnostic tool in the decadence in the early. The present were provides an introduction to processing and analysis of retinal images in OCT and taking samples from the Anterior Eye Segment. The following diseases have been invistegted using OCT images Astigmatism, Emmetrope, Myopia and Hypermetropia. The Angle Opening Distance (AOD) methods have been calculated for each case. Moreover, the Trabecular-Iris Angle (TIA) method and Trabecular-Iris-Space Area (TISA) method have been utilized to verify the decision process. Results have proved that the selected measures were efficient and the performance of the system was effective to facilitate the measurement process and saving time and effort.
