I have been told by my ophthalmologist that a have extremely narrow angles and that I am at high risk of having acute angle closure glaucoma attack.
He says I should have iridotomy to both eyes but when I google I find literally hundreds of people saying that their vision has been severely affected by iridotomy ie. lines, glare, double vision, ghosting etc.
Some have been so severely affected that they can no longer work or drive. I am extremely worried and anxious and don't know what to do?
Thanks for your question
Laser Iridotomy for narrow angle glaucoma is very important, it prevents acute angle closure glaucoma which is an urgent condition that sometimes needs hospitalization and excessive treatment to reduce intraocular pressure. Acute angle closure glaucoma if not treated properly can damage the cornea, lens and also the optic nerve and to prevent that, iridotomy is the first line.
Intraocular pressure in narrow angle glaucoma is usually normal but when the pupil is diluted due to physiological conditions such as dim light,the angle can be closed causing high intraocular pressure.
Location of iridotomy is very important, it should be between 11 o'clock and 1 o'clock. At these locations the iridotomy will be covered by the eyelid and prevent the feeling of glare and double vision. Iridotomy in other locations can cause glare, double vision, photophobia and so on because it is not cover by the eyelid.
