The primary strategy involves ‘burning’ holes in various areas within the eyes, including the ciliary and the pigmented trabecular meshwork cells.[88]\nArgon laser trabeculoplasty (ALT) targets trabecular meshwork, where it allows the aqueous fluid to leave the eye more efficiently. The procedure requires 10-20 minutes and 80% of the patients respond well to it and may eventually discontinue glaucoma medications.[89]\nThe Nd : YAG (neodymium-doped yttrium aluminium garnet) laser can also be used in closed-angle glaucoma to make a small peripheral hole in the iris, to allow the aqueous fluid to flow easily. Selective laser trabeculoplasty (SLT) delivers energy to pigmented trabecular meshwork cells in a process called photo-thermolysis. The advantage of SLT is that nonpigmented trabecular meshwork (TM) cells may sustain less damage compared with ALT.[90]"}
