Congenital Ptosis: A Rare Condition

Congenital ptosis, also known as blepharoptosis or upper eyelid ptosis, is a rare condition characterized by an abnormal drooping of one or both upper eyelids that is present at birth or shortly after. This condition occurs when the muscle responsible for lifting the eyelid (the levator palpebrae superioris muscle) is weak or underdeveloped.

Causes and Symptoms

The exact cause of congenital ptosis is often unknown, but it can be associated with various factors such as genetic conditions, birth trauma, or other underlying medical conditions. The symptoms of congenital ptosis include:

• Drooping of one or both upper eyelids
• Weakness or paralysis of the levator palpebrae superioris muscle
• Difficulty lifting the eyelid
• Blurred vision due to the drooping eyelid

Types and Severity

Congenital ptosis can be classified into different types based on its severity, including:

• Mild: The eyelid droops slightly, but vision is not affected.
• Moderate: The eyelid droops significantly, affecting vision.
• Severe: The eyelid is severely drooped, causing significant vision impairment.

Treatment and Management

The treatment for congenital ptosis depends on the severity of the condition. Mild cases may not require any treatment, while moderate to severe cases may need surgical intervention to correct the muscle weakness or paralysis. In some cases, eye drops or other medications may be prescribed to help manage symptoms.

Congenital Ptosis Signs and Symptoms

Ptosis, or drooping eyelid, can be present at birth (congenital) in some cases. The signs and symptoms of congenital ptosis may vary depending on the severity of the condition.

• Drooping of one or both eyelids: This is a common symptom of congenital ptosis, where the upper eyelid falls to a position that is lower than normal.
• Increased tearing: Babies with congenital ptosis may experience excessive tearing due to the abnormal lid position.
• Blocked vision (from severe eyelid drooping): In some cases, the drooping eyelid can block the baby's vision, leading to difficulties in seeing.
• Difficulty closing the eye or blinking: Some babies with congenital ptosis may have trouble closing their eyes or blinking normally.

Monitoring and Treatment

Depending on the severity of the congenital ptosis, patients should be monitored every 3-12 months for signs of amblyopia (lazy eye) due to congenital ptosis [6]. Early detection and treatment can help prevent long-term vision problems.

Diagnosing Congenital Ptosis

Congenital ptosis, also known as droopy eyelid, can be diagnosed through a combination of medical history, physical examination, and various diagnostic tests.

• Visual Field Test: A visual field test is often performed to evaluate the superior vision and determine if ptosis is affecting it [1].
• Anterior Segment Exam: A complete anterior segment exam, including the tear lake, corneal surface integrity, and iris coloration, should be conducted to assess the eyelid's position and function [3].
• Imaging Studies: Imaging studies such as X-ray or brain and orbit CT/MRI scans may be necessary when pathology is suspected in the regions surrounding the eye [4].
• Electromyography (EMG): EMG tests, including single-fiber electromyography, can help diagnose conditions that cause ptosis, such as myasthenia gravis [5][6].

Additional Diagnostic Tests

Other diagnostic tests may be performed to rule out other conditions or to confirm the diagnosis of congenital ptosis. These include:

• Ice Test: The ice test involves placing ice on the ptotic eyelid for two minutes and then re-evaluating the ptosis [7].
• Eyelid Measurements: Accurate measurement of the eyelid's position is crucial in diagnosing ptosis, and can be performed as part of a comprehensive physical examination [8].

Surgical Procedures

Once diagnosed, congenital ptosis can be treated with various surgical procedures, including:

• Frontal Sling: A common procedure used to treat ptosis, where a sling is created using the frontalis muscle to lift the eyelid [9].
• Levator Resection: Another surgical option for treating ptosis, which involves resecting part of the levator muscle to improve eyelid function.
• Fasanella–Servat Procedure: A procedure that involves shortening the Müller's muscle and conjunctiva to treat mild to moderate ptosis.

Unfortunately, there is no medical treatment for congenital ptosis [7]. However, there are some medical treatments available for acquired ptosis.

• Apraclonidine ophthalmic drops can be considered as a medical treatment for acquired ptosis [10].
• Botulinum toxin injection has also been explored as a potential treatment option for acquired ptosis [10].

It's worth noting that these medical treatments may not be effective in treating congenital ptosis, and surgery is still the only treatment option available for this condition.

[10] - Jun 15, 2020 — ODs can consider one of three medical treatments for ptosis: apraclonidine ophthalmic drops, botulinum toxin injection and oxymetazoline.

Differential Diagnoses for Congenital Ptosis

Congenital ptosis, or blepharoptosis, can be caused by various factors, and it's essential to consider differential diagnoses when evaluating patients with this condition. Here are some possible causes:

• Anophthalmos: A rare congenital disorder where one eye is absent or underdeveloped.
• Corneal Abrasion: A superficial injury to the cornea that can cause ptosis in severe cases.
• Cellulitis: A bacterial infection of the eyelid or surrounding tissues that can lead to swelling and drooping of the eyelid.
• Blepharophimosis syndrome: A rare congenital disorder characterized by a small upper eyelid, a short eye opening, and other facial abnormalities.
• Congenital fibrosis of extraocular muscles: A rare condition where there is an abnormal development of the extraocular muscles, leading to ptosis and other eye movement problems.
• Marcus Gunn jaw winking syndrome: A rare congenital disorder characterized by drooping of the eyelid when the jaw is moved or opened.
• Stickler syndrome: A genetic disorder that can cause a range of symptoms, including ptosis, cleft palate, and hearing loss.
• Wagner syndrome: A rare genetic disorder that can cause ptosis, cataracts, and other eye problems.

These conditions should be ruled out and documented by healthcare professionals when diagnosing congenital ptosis. Early diagnosis and treatment are crucial to prevent long-term complications and ensure proper development of the eyes and surrounding tissues.
