Conjunctivochalasis

Conjunctivochalasis, often abbreviated as CCh, is a relatively common yet frequently overlooked ocular condition. Characterized by redundant, loose, and non-edematous conjunctival tissue that often interferes with normal tear flow, conjunctivochalasis can lead to significant discomfort and visual disturbances. Let us look into the causes, risk factors, diagnosis, and treatments associated with conjunctivochalasis.

What is Conjunctivochalasis?

Conjunctivochalasis is derived from the Greek words "conjunctiva" and "chalasis," which mean "conjunctiva" and "relaxation" respectively. The condition is typified by the presence of redundant conjunctival folds, usually in the inferior bulbar conjunctiva, that can cause ocular surface irritation, epiphora (excessive tearing), and even interfere with vision. Although it is often considered a benign condition, its symptoms can significantly affect a patient’s quality of life.

Conjunctivochalasis Risk Factors

Several factors can predispose individuals to develop conjunctivochalasis. Understanding these risk factors is crucial for both prevention and early diagnosis.

Aging

Aging is one of the most significant risk factors for conjunctivochalasis. As we age, the conjunctival tissue loses its elasticity and turgor, resulting in the redundant folds characteristic of conjunctivochalasis. This age-related degeneration typically starts appearing in individuals over the age of 50.

Inflammatory Conditions

Chronic inflammatory conditions such as blepharitis, rosacea, and allergic conjunctivitis can exacerbate the development of conjunctivochalasis. Inflammation leads to tissue remodeling and degradation, which can contribute to the looseness of the conjunctiva.

Mechanical Factors

Mechanical factors such as eye rubbing and prolonged use of contact lenses can also predispose individuals to conjunctivochalasis. These activities cause repetitive trauma to the conjunctival tissue, leading to its laxity.

Dry Eye Disease

Dry eye disease is often associated with conjunctivochalasis. The redundant conjunctival folds can disrupt the tear film, exacerbating symptoms of dry eye and creating a vicious cycle of ocular surface irritation.

Causes of Conjunctivochalasis

While aging and inflammation are primary contributors, other underlying causes can also lead to the development of conjunctivochalasis.

Collagen Degradation

The conjunctiva is rich in collagen, a structural protein that maintains tissue integrity. Age-related changes and chronic inflammation can lead to collagen degradation, resulting in the characteristic laxity of the conjunctiva.

Matrix Metalloproteinases (MMPs)

Matrix metalloproteinases are enzymes involved in tissue remodeling and degradation. Elevated levels of MMPs have been found in the conjunctival tissue of patients with conjunctivochalasis, suggesting their role in the pathogenesis of the condition.

Genetic Predisposition

Although less understood, genetic factors may also play a role in the development of conjunctivochalasis. Studies have indicated a familial predisposition in some cases, suggesting that genetic factors may influence the structural integrity of the conjunctiva.

Diagnosis of Conjunctivochalasis

Accurate diagnosis of conjunctivochalasis is essential for effective management. The diagnostic process typically involves a combination of clinical examination and specialized tests.

Clinical Examination

A thorough clinical examination by an ophthalmologist is the first step in diagnosing conjunctivochalasis. The presence of redundant conjunctival folds, particularly in the inferior bulbar conjunctiva, is a key diagnostic sign. Slit-lamp biomicroscopy is often used to visualize these folds and assess their impact on the ocular surface.

Tear Film Assessment

Disruption of the tear film is a common feature of conjunctivochalasis. Tear film break-up time (TBUT) and Schirmer’s test are commonly used to evaluate tear film stability and production, respectively.

Imaging Techniques

Advanced imaging techniques such as anterior segment optical coherence tomography (AS-OCT) and confocal microscopy can provide detailed views of the conjunctival structure, aiding in the diagnosis and assessment of conjunctivochalasis.

Symptoms of Conjunctivochalasis

The symptoms of conjunctivochalasis can vary in severity and may often be mistaken for other ocular surface disorders. Common symptoms include:

Ocular Discomfort

Patients with conjunctivochalasis often experience chronic ocular discomfort, described as a sensation of grittiness or foreign body sensation.

Epiphora

Excessive tearing, or epiphora, is a hallmark symptom of conjunctivochalasis. The redundant conjunctival folds can obstruct the tear outflow pathways, leading to tear overflow.

Blurred Vision

In severe cases, the redundant conjunctival tissue can interfere with the visual axis, causing transient blurred vision.

Dry Eye Symptoms

Symptoms of dry eye, such as burning, stinging, and redness, are frequently reported by patients with conjunctivochalasis. The disruption of the tear film by the conjunctival folds exacerbates these symptoms.

Treatment for Conjunctivochalasis

Treatment options for conjunctivochalasis range from conservative management to surgical intervention, depending on the severity of the condition and the patient's symptoms.

Lubricating Eye Drops

Lubricating eye drops are often the first line of treatment for conjunctivochalasis. They help to stabilize the tear film and reduce ocular surface irritation.

Anti-inflammatory Medications

Topical anti-inflammatory medications, such as corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs), can help to reduce inflammation and alleviate symptoms.

Warm Compresses

Applying warm compresses to the eyes can help to improve tear flow and reduce symptoms of ocular discomfort.

Surgical Intervention

For patients with severe conjunctivochalasis that does not respond to conservative management, surgical intervention may be necessary.

Conjunctival Resection

Conjunctival resection involves the surgical removal of the redundant conjunctival tissue. This procedure can be performed using various techniques, including scissors, electrocautery, and laser.

Amniotic Membrane Transplantation

In some cases, amniotic membrane transplantation may be used to promote healing and restore the ocular surface. The amniotic membrane has anti-inflammatory and anti-scarring properties, making it an effective option for severe cases of conjunctivochalasis.
