WHAT IS LASER IRIDOTOMY?

Laser Iridotomy is the prophylaxis treatment for narrow angles and treatment for acute closure glaucoma.

WHO IS A CANDIDATE FOR LASER IRIDOTOMY

Patients with narrow angle glaucoma and acute angle glaucoma are candidates for laser iridotomy.

WHAT ARE NARROW ANGLE AND ACUTE ANGLE GLAUCOMA?

There is an angle formed between the iris and posterior cornea. When this angle is narrow, this is referred to as narrow angle glaucoma. With narrow angle glaucoma, the iris is appositional against the trabecular meshwork (TM), which is the drainage system of the eye, usually for 180 degrees.

Patients with narrow angle glaucoma are at risk for acute angle closure glaucoma. Acute angle closure occurs when there is sudden angle closure (usually from pupillary block) and the iris is covering the trabecular meshwork (TM).

After angle closure, there is a rapid rise in eye pressure which is a medical emergency!

WHAT ARE THE SYMPTOMS OF ACUTE ANGLE CLOSURE GLAUCOMA?

With acute angle closure glaucoma, patients experience acute/sudden

  • eye pain,
  • red eye,
  • headaches (usually one-sided),
  • nausea and/or vomiting,
  • decreased vision, loss of vision, decreased vision, blurred vision, photophobia (light sensitivity), tenders (ocular).

Narrow angle patients are at risk of pupillary block and acute angle closure patients suffered pupillary block. Pupillary block occurs when your iris is stuck against the anterior lens at the pupil border in your eye. This blocks the natural pathway and drainage of aqueous humor (intraocular fluid).

Pupillary block can lead to further narrow angling and appositional closure of the iris against the Trabecular meshwork (TM) leading to extremely high eye pressures which is a medical emergency.

Laser iridotomy creates a hole in the peripheral iris, which allows an alternate route for aqueous humor therefore bypassing the pupil. When aqueous is able to enter the anterior chamber the iris move back to its natural position (not against the TM) and aqueous can drain out of the eye.

Laser iridotomy is an outpatient procedure that can be performed in the office.

Laser Trabeculoplasty (LTP) is a outpatient office procedure for patients with open angle glaucoma. It serves as a primary (first-line) therapy or adjunctive therapy (used with topical glaucoma medication, eye drops).

LTP can lower eye pressure (IOP) up to 30%. The effect of LTP is temporary (lasts month to years) and not permeant (not curative) therefore patients need to follow up with their providers for future treatment options.

LTP has the potential to last 3 to 5 years for some patients but has decreased efficiency after each passing year after initial treatment.

The laser targets the pigmented drainage system of the eye, the trabecular meshwork (TM). The laser treatment is usually performed with argon, diode, double-frequency neodymium: yttrium-aluminum-garnet (Nd:YAG).

This laser procedure is usually recommend if patients cannot tolerate some eye drops, never used topical medication, inconsistent use of topical medication, or are on maximum topical treatment for glaucoma.

YAG capsulotomy is a specialized laser procedure that aims to address a common occurrence following cataract surgery called posterior capsule opacification (PCO). PCO can lead to a gradual clouding of the vision, resembling the symptoms of cataracts. At Peachtree Ophthalmology, we offer YAG capsulotomy as an effective solution to restore clarity and enhance visual acuity.

HOW YAG CAPSULOTOMY WORKS?

After cataract surgery, a clear artificial lens, known as an intraocular lens (IOL), is implanted to replace the cloudy natural lens. Over time, some patients may experience PCO, where the capsule behind the IOL becomes thickened and cloudy. This can cause a decline in vision, similar to the initial symptoms of cataracts.

During YAG capsulotomy, a laser is used to create a small, painless opening in the cloudy posterior capsule. This opening allows light to pass through and reach the retina, restoring clear vision. The procedure is quick, typically lasting only a few minutes, and patients often notice an immediate improvement in their vision.

BENEFITS OF YAG CAPSULOTOMY:

  • Improved Vision: YAG capsulotomy effectively addresses the clouding that can occur after cataract surgery, providing patients with clearer and sharper vision.
  • Non-Invasive Procedure: The laser procedure is non-invasive and does not require surgical incisions. It is performed in an outpatient setting, and patients can return to their normal activities shortly after.
  • Quick and Painless: YAG capsulotomy is a quick and painless procedure. Most patients experience minimal discomfort, and anesthesia is not typically needed.
  • Long-Lasting Results: Once the cloudy capsule is treated with YAG capsulotomy, the results are generally long-lasting, with no need for further interventions.

If you are experiencing vision changes after cataract surgery or suspect you may have PCO, contact Peachtree Ophthalmology at 770-285-7910 to schedule a consultation.  Don’t let cloudy vision persist – explore the benefits of YAG capsulotomy and regain the clarity you deserve.
