What is blebitis?
The term blebitis was introduced in 1994 by Brown et al. to describe a presumed infection in or around a filtering bleb without vitreous involvement; it could be associated with mild to moderate anterior chamber (AC) reaction.
What is bleb dysesthesia?
Bleb dysesthesia is an uncommon complication of glaucoma filtration surgery in which a well-functioning, but large filtering bleb with adequate intraocular pressure (IOP) control causes ocular discomfort [2–4] due to the effect of interrupted tear film distribution over the bleb and cornea [5].
What is bleb failure?
Blebs can fail because the internal ostium is blocked by the iris, a membrane or fibrin and vitreous. Episcleral fibrosis can cause closure of the flap margins lining the bleb and can cause an encapsulation. Collagen within the bleb occurs in 10% to 14% of cases. “The problem is how to manage these blebs,” Dr.
What is needling in glaucoma?
Needling involves breaking down the wall of the scar using a fine needle to improve the drainage of fluid inside your eye. A jelly like material and an anti-scarring medicine is then injected to try to prevent further scar formation.
How is Blebitis treated?
Blebitis can usually be treated with intensive topical antibiotics (such as fortified gentamicin and cefazolin) alone 2….
- Hospitalization.
- Intravenous antibiotic therapy.
- Hourly topical fortified antibiotics.
- Cycloplegicss.
- Topical or intravitreal steroids.
- Vitrectomy in cases of worsening despite aggressive therapy.
What is bleb?
Definition of bleb 1 : a small blister. 2 : bubble also : a small particle. 3 : something resembling a bleb especially : a vesicular outgrowth of a plasma or nuclear membrane.
What does an eye bleb feel like?
In general, you can think of it as a spectrum of symptoms, including ocular discomfort, that patients may feel after filtering surgery. Those symptoms include tearing, pain, ocular surface irritation (for example, foreign-body sensation) and/or persistently fluctuating vision—especially when the patient blinks.
What is the difference between Trabeculotomy and trabeculectomy?
The basic indications for the surgery were as follows: Trabeculectomy was indicated for the cases with moderate to severe visual field loss or need of lower postoperative intraocular pressure, and trabeculotomy indicated for those with early stage of POAG.
What does an eye bleb look like?
The bleb typically has a milky-white appearance with loss of clarity, and you may observe a pseudohypopyon within the bleb. A positive Seidel’s test is common. Some pa-tients may have hypotony, and even a flat anterior chamber.
What is a bleb needling?
Bleb needling is an alternative to surgically revising the bleb, repeating trabeculectomy, or implanting a tube shunt. HISTORY. In 1941, Ferrer1 described conjunctival dialysis, which consisted of incising the scar tissue and then separating the conjunctiva from the sclera with a spatula.
What is needling after trabeculectomy?
Trabeculectomy is generally a successful procedure for reducing intraocular pressure (IOP) in glaucoma patients. However, failure of the filtering bleb may occur. Needling is a minimally invasive procedure used to re-establish aqueous flow in the eye in the event of bleb failure.
