Doctor insights on:
Can some of the iridotomy risks be predicted based on the eye tests pre surgery? Read about retinal detachment after the procedure in some cases.
Glaucoma: If the iridotomies are open and functioning there should be no problem.
Not difficult: You will receive eye drops to shrink the pupil, prevent pressure rise, resist inflammation and numb your eye. A special lens will placed against the eye and the laser used to make one or more tiny holes in the iris. The procedure is not uncomfortable and takes only a few minutes to perform.
Your ophthalmologist: Ask your surgeon! This is one area that laser treatment is fabulous for, and ophthalmologists have extensive laser training (i'm a plastic surgeon, but my dad was an optometrist, and my sister is a board-certified ophthalmologist.) in expert hands you should do splendidly. Good luck!
Hole in the iris: This procedure is done in order to lower the risk of angle closure in patients with anatomically narrow angles. If the iris and the cornea are in close proximity they may touch and by doing so, block the drainage pathway of the eye. The hole made by the yag laser serves to provide a pathway for fluid to move between the front and back of the eye.
Excellent: This is a curative procedure for narrow angle glaucoma and works very well. It is usually done in both eyes.
Maybe: All surgical and laser procedures have risk. It is possible to irritate or even damage the cornea when doing a laser iridotomy. The reason to do an iridotomy is usually to treat or prevent episodes of very high eye pressure. These episodes can cause permanent eye damage, so if you have a condition that merits an iridotomy the risks of not doing the laser could be worse than the laser itself.
YAG iridotomy at 12 o'clock position. Have ghost images in lower field of vision. Looks kind of like a line/crescent of light Will these resolve?
Most often yes: Sometimes no, if it does not, please look into a corneal tattoo (rarely needed but works very well to block the extra light coming through or colored contact lens.
Cataract?: A prophylactic laser peripheral iridotomy is performed when a person has narrow and occludable iridocorneal angles, which can cause acute angle closure glaucoma and profound to total vision loss. The hole in the iris is a "pressure release valve" to prevent angle closure, but the inflammation or treatment following the procedure can increase the pace of cataract formation. Check your glasses too.
Iridotomy: An Iridotomy is performed in patients who have a narrow angle (narrow internal eye drain area: see eyedoc2020@blogspot. Com for more info). The laser makes a microscopic hole in the peripheral iris to help fluid get into drain easier. Creating the hole can make vision blurry from inflammation in eye. Halos can happen due to hole depending on location. What clock hour did they make the hole & when?
I'm getting laser iridotomy soon in both eyes. Is it true that positioning the hole at 3 or 9 o'clock is better to avoid light aberrations? Thanks!
Iridotomy: First, make sure you need the procedure. Then to prevent light aberration the best location would be between 11 and 1 o'clock where the upper lid would block incoming light.See 1 more doctor answer
No: No this procedure should not damage the cornea but can cause some short term irritation of the cornea.
Is there a safe sinus relief medication for a person with narrow angle glaucoma? I have had bilateral iridotomy
It depends: Sometimes, despite iridotomies, the angle may remain narrow and any drugs that cause pupil dilation, either systemic or nasal spray, can increase angle closure and cause elevated pressure. I will sometimes recommend a mild nasal steroid if there is no evidence of infection. You need to consult with your eye surgeon as to the severity of your narrow angles and weigh risks/benefits of treatment.See 2 more doctor answers
Are you supposed to have a small pupil (unequal to the unaffected eye) after iridotomy and, if so, for how long?
Frequently: Iridotomy is done to protect your eye from an acute attack of glaucoma due to narrow angles (the space between the edge of the iris and the cornea). Usually a laser is applied to the iris to create a hole which by passes the normal fluid pathway preventing the problem. Your surgeon might have put into your eye a pupillary constrictor to aid in this and this makes the pupil smaller on that side.See 1 more doctor answer
My mom has Glaucoma. She has effectively controlled the pressure with drops, Iridotomy and SLT surgery 2 times about 3 years apart.
