Mild-Severe Conjunctivochalasis

Conjunctivochalasis (CCH) is defined as a loose, redundant, nonedematous conjunctiva that is considered to occur secondary to normal aging. At times CCH may be asymptomatic and, therefore, is sometimes overlooked by the physician. However, CCH can be a possible origin of ocular surface irritation and tearing. When severe, CCH can also lead to blurred vision, mucous discharge, dryness, ocular fatigue, and subconjunctival hemorrhage.

CCH is usually bilateral and most commonly involves the inferotemporal conjunctiva.

Etiology is uncertain but is likely associated with age or eye rubbing (i.e. allergic conjunctivitis).

Risk Factors

Risk factors for CCH include age, eye rubbing, ocular surface disease, allergic conjunctivitis, dry eye, contact lens wear, hyperopia, pinguecula, UV exposure, eyelid disorders, and thyroid disease. [1]

General Pathology


The etiology of conjunctivochalasis has not been completely elucidated. In a prospective clinical and histopathological study of 29 patients, 22 showed demonstrated normal conjunctival histology, while 4 specimens revealed inflammatory changes, and 3 specimens showed elastosis. The authors concluded and hypothesized that the etiology is multifactorial, including local trauma, UV radiation and delayed tear clearance as triggers of the disease. [2]

Watanabe et al. demonstrated subconjunctival microscopic telangiectasia in 4 of 39 specimens taken from patients with severe conjunctivochalasis, with no evidence of inflammation. They also noted fragmented elastic fibers and sparse assemblages of collagen fibers in 44 specimens. They concluded that mechanical forces between the lower eyelid and conjunctiva gradually impaired lymphatic flow, resulting in lymphatic dilation and clinically redundant conjunctiva. [3] Even though there is little to no histopathologic evidence to support inflammation as a major contributor to conjunctivochalasis, mechanistic evidence suggests a shift in the normal balance of the conjunctival matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs).

Li et al. showed overexpression of MMP-1 and MMP-3 mRNA in tissue cultured conjunctivochalasis fibroblasts, versus normal human conjunctival fibroblasts. Further studies showed that inflammatory mediators TNF-å and IL-1ß may increase the expression of MMP-1 and MMP-3 in conjunctivochalasis fibroblasts. Other inflammatory cytokines were also found in increased amounts in tear film of patients with conjunctivochalasis (IL6 and IL8). After these observations, the authors concluded that the disrupted interaction of MMPs and their inhibitors may lead to a manifestation of a redundant and lax conjunctiva. [4]

Huang et al. studied whether conjunctivochalasis interferes with tear flow from the fornix to the tear meniscus and depletes the fornix tear reservoir. In this study of 24 patients with conjunctivochalasis (8 asymptomatic and 16 symptomatic), 9 pateints underwent operative correction.[5] The study found that the recovery rate of the tear meniscus was significantly slower in symptomatic than asymptomatic patients when compared to normal subjects. Deepening of the inferior fornix by removing degenerated Tenon’s and performing a fornix reconstruction with amniotic membrane improved the recovery rate in symptomatic patients. The authors concluded that the tear reservoir in the fornix rapidly replenishes the meniscus under normal circumstances, so in patients with conjunctivochalasis, there is impaired formation of the normal tear meniscus as well as limitations in normal tear movement from the fornix.

Primary prevention

Patients may avoid eye rubbing and UV exposure and can treat any underlying ocular surface issues. CCH occurs largely secondary to age, however, so preventative strategies are limited.




Patients often describe insidious onset of ocular discomfort, foreign body sensation, dryness, and tearing. Some patients have been treated for dry eye with limited improvement.

Physical examination

Slit lamp biomiocroscopy reveals a prolapse of the conjunctiva over the lower lid margin in temporal, medial or nasal regions, in some cases occluding the inferior puncta resulting in epiphora and even blurred vision.


Signs on examination include redundant conjunctiva that overlaps eyelid margin, especially over the inferior temporal region. Also, the conjunctiva is easily mobilized by pressing on the eyelid and moving the loose conjunctiva up and down.


Symptom onset can be insidious, and patients may be misdiagnosed with dry eye or other ocular surface conditions. Symptoms include foreign body sensation, burning, dry eyes and discomfort, many of which result from a disruption of the inferior tear meniscus and, thus, an unstable tear film.

Clinical diagnosis

The diagnosis is clinical.

Diagnostic procedures

OCT images from the anterior segment may be helpful to evaluate the tear meniscus and gross anatomy of the lateral canthus.

Laboratory testing

As a result of disrupted tear circulation, changes in tear osmolarity may be observed but are not necessary for the diagnosis.

Differential diagnosis

Dry eye syndrome, Sjögren syndrome, meibomian gland dysfunction, blepharitis, allergic conjunctivitis


General treatment

Management should be individualized according to the severity and symptoms of each patient. No treatment is needed if the patient is asymptomatic.

Medical therapy

Mild symptoms can be addressed with topical lubrication, blinking exercises, topical antihistamines, and topical corticosteroids.


Surgical therapy most commonly involves conjunctival excision, typically a semilunar portion of conjunctiva 5 mm posterior to the limbus. The conjunctiva can be closed with absorbable suture or with fibrin glue. Amniotic membrane can also be used to fill in the conjunctival defect.

Thermal cautery can also be performed to tighten loose or redundant conjunctiva. Under topical subconjunctival anesthesia, the redundant conjunctiva is grasped gently with a forceps and thermal cautery is applied over this redundant conjunctiva to cause a contraction of the tissue.

Forniceal reconstruction with amniotic membrane (discussed above) is another option for severe conjunctivochalasis in order to re-establish the forniceal tear reservoir.


Conjunctivochalasis can be complicated by dry eye symptoms and pain when severe.


Prognosis is good with proper diagnosis and treatment.
