Is there an order of priority between conventional surgery and laser treatment? Conventional surgery in this case refers to trabeculectomy as a filtering procedure, and laser treatment in this case refers to YAG laser peripheral iridotomy (LPI). YAG laser peripheral iridotomy is primarily a good treatment for early stage closed-angle glaucoma of the pupillary block type. When laser treatment is ineffective, or in advanced closed-angle glaucoma, especially in those with a large range of atrial angle adhesions, other methods of treatment such as IOP-lowering medications or even trabeculectomy are usually required. However, in some foreign medical units, as long as the disease is not too advanced or the eye condition is suitable for laser treatment, laser treatment is started, and then medication and surgery are used if it is not effective. What are the effects of the different types of laser treatment? Will it stop recurring? In addition to the YAG laser peripheral iridotomy (LPI) described above, laser peripheral iridoplasty, selective laser trabeculoplasty (SLT), and diode laser transscleral ciliary photocoagulation are also available for glaucoma. Each method has specific indications. YAG laser peripheral iridotomy and laser peripheral iridoplasty generally do not recur as long as the indications are appropriate; SLT and ciliary body photocoagulation are more common postoperative recurrences. Can I keep my eye pressure normal for a long time after laser treatment? Can it delay vision loss? As mentioned above, as long as the indications are properly selected, IOP can remain normal for a long time after surgery, thus delaying the progression of visual impairment, including, of course, visual acuity. However, glaucoma is mostly in the elderly, and there are many cases of combined cataracts or other diseases, and the refractive status is changing, so vision loss sometimes needs to be analyzed through detailed examination. Can I have laser treatment in both eyes at the same time? Primary angle-closure glaucoma is a bilateral disease, and the anatomical patterns of both eyes are similar. ☆ Do I need laser treatment in one eye if I have an acute attack in the other eye? Yes. After an acute attack of primary angle-closure glaucoma, a detailed examination of the anterior segment of the eye and fundus of the other eye is required. The other eye is usually preclinical glaucoma and has a higher chance of having an attack within the next 5 years. What should I do if there is no significant decrease in IOP after laser treatment? Laser peripheral iridotomy is usually ineffective in non-pupillary blocked closed-angle glaucoma; it is also not effective in closed-angle glaucoma with a large range of atrial angle adhesions. Intraocular pressure may remain high after surgery, requiring further medication or surgical treatment. ☆ Do I still need long-term medication to lower IOP after laser treatment? How do I use them? If you use medication, you usually need to use it for a long time. After taking IOP-lowering medication, you need to observe the effect of the medication, including whether the IOP can be controlled to normal and whether the fundus damage progresses. The specific medication usage depends on the condition and the characteristics of the medication itself, etc. What happened when the pupil shrank very small after regular medication after laser treatment? What can I do about it? What should I do if I find that my pupil has become larger after surgery? The pupil shrinkage is due to the use of the pupil-shrinking agent Maurozine, which should not be used for as long as possible. Long-term use may cause post-iris adhesions and aggravation of cataracts, etc. Post-laser surgery pupil enlargement is caused by uncontrolled intraocular pressure, the use of pupil-dilating agents, and the manifestation of advanced glaucoma.
