How do you assess for ptosis?
Proper evaluation for ptosis is essential in identifying any asymmetry and can help elucidate the etiology of the ptosis. Proper evaluation involves taking accurate measurements of the eyelids, which includes the margin to reflex distance (MRD), levator function, palpebral fissure, and the superior lid crease.
How do you describe ptosis?
Ptosis, also referred to as blepharoptosis, is defined as an abnormal low-lying upper eyelid margin with the eye in primary gaze. The normal adult upper lid lies 1.5 mm below the superior corneal limbus and is highest just nasal to the pupil.
How do you rule out Pseudoptosis?
Pseudoptosis was confirmed–and true ptosis ruled out–by taping the excess eyelid skin up and out of the way so that the normal height of the upper eyelids was demonstrated (B) and the patient’s superior and lateral visual fields significantly improved in both eyes.
What is the purpose of ptosis test for preclinical evaluation?
 This test is very important in determining the surgical procedure of choice for ptosis correction. Margin-reflex distance: Patient fixates on torchlight held by the examiner and the distance between its corneal reflection and the upper lid margin is measured.
Who do you see about ptosis?
Your ophthalmologist determines the type of ptosis based on your medical history and the results of the comprehensive eye exam the doctor may have performed. You may then be referred to an oculoplastic specialist—an ophthalmologist with advanced training in plastic surgery of the eyes and surrounding areas.
How is the levator function test performed?
Levator function is measured by having the patient look down, and with a hand on the patient’s forehead to prevent any brow action, asking the patient to look upward as far as possible without a change in head position. The distance the upper lid margin elevates in millimeters is the levator muscle function.
How can you tell the difference between ptosis and Pseudoptosis?
Characteristically, pseudoptosis patients with orbicularis spasm have a depressed eyebrow with variable ability to elevate the frontalis muscle, compared to organic ptosis patients who generally exhibit frontalis muscle overactivity to compensate for true ptosis.
What is ptosis correction?
Ptosis surgery is an operation to tighten the muscle that lifts your upper eyelid. As you get older, the levator muscle that lifts your upper eyelid stretches and weakens, causing your eyelid to sag.
What are the side effects of ptosis?
- Drooping eyelids. Drooping of the upper eyelids is the most common symptom recognized in ptosis.
- Crossed eyes.
- Double vision.
- Tilting head back in order to see.
- Eye and forehead fatigue.
- Difficulty closing the eye or blinking.
- Dry or watery eyes.
What are the types of ptosis according to cause?
Types of Acquired Ptosis
- Aponeurotic ptosis. Senescent slippage of the aponeurosis is the most common cause of mild to moderate ptosis in the elderly.
- Myogenic ptosis. Dysfunction of the levator muscle prohibits the eyelid from being elevated into proper position.
- Neurogenic ptosis.
- Mechanical ptosis.
- Traumatic ptosis.
