What is CCH (Conjunctival Chalasis)?

Conjunctivochalasis (CCh) is loosened, shortened and wrinkled conjunctiva, which interferes with the tear meniscus and diminishes the fornix or tear reservoir. This is caused by the underlying Tenon’s capsule being degenerated or dissolved by matrix metalloproteinase (MMPs). This wrinkled tissue occupies the tear reservoir and prevents the eye from holding tears, causing pain and irritation that feels similar to dry eye symptoms. Often, some of the wrinkled conjunctival tissue can disrupt the tear meniscus, at the edge of the eyelids. The tissue acts as the tip of an iceberg, which reflects only a portion of the underlying condition. When you blink, this wrinkled conjunctiva can rub against the eye, causing further irritation and redness to an already inflamed and dry eye. 

For CCh patients who do not respond to medical treatment, the Reservoir Restoration Procedure can resolve interference with the tear meniscus and using cryopreserved amniotic membrane will restore the tear reservoir to its normal state and expedite a patients’ recovery.

Pterygium is a benign vascular pink tissue that can grow from the conjunctiva onto the cornea.  If it grows into the line of vision, over the pupillary aperture, it can interfere with vision. Pterygium is most commonly found to originate from the inner, nasal, surface of the eye and extend toward the pupil.  They can also occur on the temporal side of the eye.  Pterygium is more common in countries or states closer to the equator, therefore long-term exposure to sunlight, particularly UV rays have been a suggested cause.

With pterygium, the primary goals are to achieve no recurrence, fast recovery, and excellent cosmetic outcome.
