![]() ![]() Ask the patient to look at a near object (4-6 inches away from the eyes), and then move the object out to a distance of 12 inches. When light reaches a pupil there should be a normal direct and consensual response. IN MANY PATIENTS ABNORMAL PUPIL RESPONSE TO CHROMATIC STIMULI (RED AND BLUE LIGHT) IS THE VERY EARLY SIGNS OF RETINA OR OPTIC NERVE DISEASE, WHICH CAN. ![]() Convergence refers to the action of both eyes moving inward as they focus on a close object using near vision. Swing a light back and forth in front of the two pupils and compare the reaction to stimulation in both eyes. Recall that accommodation refers to the ability of the eye to adjust from near to far vision, with pupils constricting for near vision and dilating for far vision. Abnormal Pupil Shape-Dyscoria congenital misshapen pupil-e.g. In these cases, there are no other symptoms and both of the persons pupils react to changes in light. mydriasis-Probably part of the aniridia spectrum. This is called physiologic anisocoria and is normal. Test eye convergence and accommodation. Abnormalities of Pupil Structure Abnormal Pupil Size-Congenital miosis (microcorea)-Due to dilator absence/malformation, or fibrous contraction-Associated with multiple congenital.An unexpected finding is when one pupil is larger than the other or one pupil responds more slowly than the other to light, which is often referred to as a “sluggish response.” It is a skill required in eye casualty, clinics and perhaps most importantly, exams. \) for an image of a nurse assessing a patient’s pupillary reaction to light. Understanding pupillary reactions is vital in understanding basic neuro-opthalmology.
