Selective Laser Trabeculoplasty in the Era of OTC Blood Thinners: Hyphema and IOP Spikes Selective Laser Trabeculoplasty (SLT) and Argon Laser Trabeculoplasty (ALT) are laser treatments used to lower eye pressure in glaucoma. SLT uses a short, low-energy laser pulse to target just the pigmented cells of the eye’s drainage mesh (the trabecular meshwork) (pmc.ncbi.nlm.nih.gov), whereas ALT (older te...
Introduction High eye pressure in conditions like open-angle glaucoma or ocular hypertension can damage vision over time. Traditionally, doctors start treatment with daily medication drops to lower intraocular pressure (IOP). However, Selective Laser Trabeculoplasty (SLT) is a one-time laser treatment that safely opens the eye’s drainage angle to help fluid escape and lower IOP (pmc.ncbi.nlm.nih....
Selective Laser Trabeculoplasty (SLT) is a short, clinic-based laser procedure used to lower pressure inside the eye by helping fluid drain more easily through the eye’s natural drainage system. It works by delivering low-energy laser pulses to specific cells in the drainage tissue, which stimulates a biological response that improves outflow without causing widespread tissue damage. The treatment is usually done with numbing drops, takes only a few minutes, and patients can go home the same day. Many people experience a meaningful drop in intraocular pressure that can last months to years, and the procedure can often be repeated if the effect wears off. SLT can reduce or delay the need for daily eye drops, which helps some patients who have trouble with medication routines. Like any treatment, it has potential side effects: temporary inflammation, a brief spike in eye pressure, or rare bleeding inside the front of the eye; doctors weigh these risks especially when people are taking blood-thinning medicines. SLT is most commonly used for the common form of glaucoma where the drainage angle is open, and it may be offered as an initial treatment or as an addition to medications. Its relative simplicity, repeatability, and ability to improve adherence make it an important option in long-term eye care. Choosing SLT depends on the individual’s eye condition, other health issues, and treatment goals, so a discussion with an eye specialist helps determine whether it’s a good fit.
