Abstract	Strabismus, the misalignment between the eyes, is a prevalent condition observed in the medical field. It is found in infants; patients affected by cerebral palsy and may also occur due to over usage of drugs. Nystagmus is a condition that causes involuntary, rapid movement of one or both eyes. The eye(s) may move from side to side, up and down, or in a circular motion. It is common for individuals with this condition to tilt their heads to compensate for their difficulty seeing. The individuals with these disorders are associated with difficulty in climbing stairs, reading or driving. The brain fails to take images from one of the eyes and the unused eye eventually turns blind. In the present eye examination system, to test for these disorders, manual analysis is done by a doctor or examiner. This includes the cover-uncover test where the person manually covers the affected eyes intermittently to observe the change in alignment. Also, caloric reflex test, in which warm or cold water or air is poured into one ear. Results of manual tests may vary for each patient depending on the eye examiner taking the test. To standardize the testing process, a novel real time electrooculography based system is proposed. Bio sensors are used in this system to acquire EOG to identify/track the difference in alignment of both the eyes. This can ensure the fast and accurate detection of strabismus or nystagmus affected eyes.
