What is conjunctival redundancy?
What is conjunctival redundancy?
Redundancy of conjunctiva typically occurs at the inferior temporal limbus. Many patients with this finding are asymptomatic, but this redundancy often leads to subconjunctival hemorrhages and painful “capturing” of the conjunctiva at the limbus with eyelid movement.
What is conjunctival excision?
Conjunctival resection is an effective therapeutic modality for the treatment of a marginal furrow associated with rheumatoid arthritis. Rapid reepithelialization was observed following this procedure for the treatment of five such stromal ulcers that occurred in three rheumatoid patients.
What causes redundant conjunctiva?
Conjunctival chalasis is characterized by loose or redundant conjunctival tissue. Conditions that may cause conjunctival chemosis include longstanding allergic conjunctivitis; dry eye; trauma and inflammatory conditions, such as episcleritis.
What is conjunctival tissue?
Answer. The conjunctiva is a loose connective tissue that covers the surface of the eyeball (bulbar conjunctiva) and reflects back upon itself to form the inner layer of the eyelid (palpebral conjunctiva). This tissue firmly adheres to the sclera at the limbus, where it meets the cornea.
Can you go blind from conjunctivochalasis?
The conjunctiva is the tissue found on the surface of the eyeball, and people with conjunctivochalasis will have a thin layer of skin beneath their lower eyelids. As the skin droops, it can cover a person’s cornea and lead to vision impairment.
Does conjunctiva heal itself?
The infection will usually clear up in 7 to 14 days without treatment and without any long-term consequences. However, in some cases, viral conjunctivitis can take 2 to 3 weeks or more to clear up. A doctor can prescribe antiviral medication to treat more serious forms of conjunctivitis.
How are conjunctival lesions treated?
The traditional treatment of CIN is excision with margins of 1mm to 5mm, depending on the extent and history of primary and recurrent lesions. Corneal involvement is debrided with a surgical blade, and cryotherapy is applied to the bed and conjunctival edges.
How do you perform a conjunctival biopsy?
The palpebral conjunctival is exposed and a specimen is taken from the area between the inferior border of the tarsus and the fornix. This biopsy can be taken with toothed forceps and Westcott scissors.
How do you fix a conjunctiva?
There are many possible surgical procedures to treat conjunctivochalasis, all of which involve excising the excess tissue, tightening the loose tissue, or replacing the abnormal conjunctival tissue. Conjunctival cautery can be used to create superficial scarring and tightening of the tissue.
What causes changes in conjunctiva tissue?
A pinguecula is caused by changes in your conjunctiva tissue. These changes have been linked to irritation caused by sun exposure, dust, and wind, and are more common as we age. These bumps or growths may contain a combination of protein, fat, or calcium, or a combination of the three.
Does the conjunctiva regenerate?
The epithelial tissues of the ocular surface (cornea and conjunctiva) are regenerated from stem cells. The junction of the conjunctiva and the cornea, the limbus, is the major source of stem cells that replaces the epithelium of the cornea [12–14].
How do you get rid of conjunctivochalasis?
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.
