What is the use of conjunctival flap?

The conjunctival flap is an acknowledged surgery for the treatment of various corneal diseases with a chronically compromised ocular surface, such as severe dry eye, neurotrophic or neuroparalytic disease, or bullous keratopathy.

What is conjunctival hooding?

The procedure of using the conjunctiva to cover the entire cornea – Gundersen’s flap, can be performed using orbital infiltration anesthesia. A 6-0 silk or vicryl corneal suture is used to pull the globe in an inferior direction, to allow access to the superior bulbar conjunctiva.

What causes Conjunctivochalasis?

Conjunctivochalasis is not caused by any one particular thing, but it’s believed that the natural ageing process is the primary cause. As a person ages, the conjunctiva begins to thin out and stretch. Another common cause of conjunctivochalasis is prolonged exposure to contact lenses.

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].

What is the flap in Lasik surgery?

During LASIK surgery, a small flap is created in the frontal, topmost layer of the cornea. This layer is called the epithelium. Using this epithelial flap, the cornea can be reshaped and recontoured as needed to address refractive errors (i.e., myopia/nearsightedness, hyperopia/farsightedness, and astigmatism).

What is conjunctival retraction?

This suture retracts the conjunctiva, exposing the adjustable muscle-suture apparatus while simultaneously fixating the globe. A novel way of tying the noose around the pole sutures and preventing noose slippage is also presented.

What is amniotic membrane in eye?

Amniotic membrane is widely used in eye surgery as a biological bandage to heal or replace damaged eye tissue. It is thin, lightweight, elastic and almost transparent making it suitable for use on the surface of the eye. It can be sutured or glued into place with tissue glue.

How do you get rid of conjunctival concretions?

If concretions are causing symptoms, the optometrist may offer to remove them. After numbing the eye surface with an anaesthetic drop, the concretions can usually be teased out with the tip of a hypodermic needle. Rarely, antibiotic drops may be prescribed.

Why is the skin on my eyeball loose?

Conjunctivochalasis, or CCH, is a fairly common ocular condition that is characterized by excess folds of conjunctival skin that accumulate between the globe of the eye and the margins of the eyelid. This can cause the patient to experience unpleasant and uncomfortable symptoms.

How do you cure conjunctiva?

To help relieve some of the inflammation and dryness caused by conjunctivitis, you can use cold compresses and artificial tears, which you can purchase over the counter without a prescription. You should also stop wearing contact lenses until your eye doctor says it’s okay to start wearing them again.

What is difference between sclera and conjunctiva?

Select eye findings in conjunctival disorders Edema of the bulbar conjunctiva results in a diffusely translucent, bluish, thickened conjunctiva. Gross edema with ballooning of the conjunctiva, often leading to prolapse of conjunctiva, is known as chemosis.

How effective is conjunctival flap for ocular surface disease?

In specific situations, the conjunctival flap is effective and definitive treatment for persistent ocular surface disease.59–62 Patients are relieved of pain, frequent regimen of topical medication, as well as more invasive surgery or enucleation.

How do you fix a perforated conjunctival flap?

Nylon or Vicryl sutures may be used to fix the flap into place ( Fig. 36.8C,D ). Total conjunctival flaps should not be used in frank perforations. Once the flap is in place, the integrity of the anterior chamber cannot be monitored and, in general, a flap will not seal a perforation.

How is the conjunctival flap freed after A peritomy?

When the limbus is reached, the resultant flap is freed with a 360-degree peritomy. Bleeding in the dissection bed is controlled with cautery. The traction suture is released and the conjunctival flap is pulled down over the cornea ( Fig. 36.5F ). Relaxing incisions may help to release tension.

How is a corneal lesion in the superior bulbar conjunctiva treated?

Following appropriate measurements and marking in the superior bulbar conjunctiva, a thin flap is dissected from periphery to limbus, and released with a limited peritomy ( Fig. 36.6B ). The flap is then mobilized to cover the corneal lesion and fixed into place with Vicryl or nylon sutures ( Fig. 36.6C ).
