Perrla Eye Exam begins with attention to the eyelash and eyebrow distribution of the patient. Eyebrows should extend wide to meet the eyes and eyelashes will curl out over the eyes. You can look for loose eyelids at the bottom or top. You should pay attention to the color of the sclera or the white eye and look for defects. You can describe the swelling of the conjunctiva and the thin membrane that covers the eye.
You will draw the low cap and record the conjunctiva. You can check each slice and record the shape and size of the pupil. Pupils should have the same size, round, and without turbidity. You can use the penlight to give a bright light to the pupil. Pupils will respond to light and narrow. You should pay attention to the consensual and direct responders. You can hold your finger and place the finger a few inches from the patient’s eyes. You should ask the patient to look at your finger from a distance so that you can see the accommodation of the pupil. The normal pupil will widen for a distant gaze and narrow to see the object close. Patients with spherical pupils and can react to light have cranial nerves II and III. You can clean the pen rays and see the glow in the eyes of the patient. The luster should be symmetrical.
Eye Perrla Exam Confrontation
Both eyes have an overlapping visual field so each eye must be independently tested. Each patient should close his right eye with his right hand. The nurse sits across from the patient and directs her eyes to the examiner’s eyes. This test can be done using a moving object or stationery. The moving target starts outside the visual field and moves to a central position so that the patient can see the target. Stationary testing is done by the nurse will hold the fingers of the same distance in the patient. The patient will be asked to see the number of the finger. Four quadrants must get the right test. The target stationer can produce the better stimulus for the retina than the moving target. This target can be easily identified by the patient. Colored targets also become more sensitive than white targets.
Perrla Physical Exam
The first part of this examination is the assessment of visual acuity. This can be done by using a standard Snellen wall hanging chart that should be read by a patient standing at a distance of 20 feet. Eyes will be tested independently. Patients can use the glasses to see the object clearly. You do not need to assess the patient’s ability to read every row in the table. You must jump fast on small characters. The number at the end of the line is an indication of the patient’s sharpness compared to the normal subject. If the denominator is getting bigger, then the sharpness of the eyes is getting worse.

Patients have poor vision and cannot detect the number of fingers, motion or light in front of them. Pinhole testing can be performed to determine the sharpness. Possible sharpness problems may occur due to errors of refraction and other factors. The pinhole can make the light perpendicular to the lens so that the light does not need to be bent to get to the retina. The patient should look at the chart with holes above and below. If there is a deficit, then the problem of acuity is related to refraction. That is the process of Perrla Eye Exam.
