Background & aim: Drug treatment, laser and surgery are among the treatments for reducing ocular pressure in glaucoma patients. Although laser is a safe treatment, some parameters may be affected. Therefore, the aim of the present study was to determine and evaluate laser trabeculoplasty in patients with primary wide-angle glaucoma and ocular hypertension.
Methods: In this prospective descriptive study that was performed in Farshchian Hospital in Hamadan in 2017-2018, 56 patients with primary open-angle glaucoma and hypertension diagnosed for the first time or did not have uncontrolled eye pressure despite receiving medical treatment, underwent Laser treatment of selective trabeculoplasty were selected. Intraocular pressure, anterior segment parameters and macular thickness were measured in the 5 upper, lower, foie, nasal and temporal regions before the laser and at intervals of 1, 3 and 6 months after the laser and were compared between the two groups. The collected data were analyzed using Chi-square and t-test.
Results: Intraocular pressure decreased in both groups in the follow-ups(p<0.05). The macula increased slightly in the 1st and 3rd months after the laser, and except in the temporal region in the wide-angle glaucoma group, in the sixth month the macular thickness reached baseline in all areas and in both groups. The central corneal thickness, despite a slight increase in the first month, had a downward trend in other follow-ups, the changes of which were significant in the ocular hypertension group (p<0.05). The volume and depth of the anterior chamber also decreased significantly in both groups (p<0.05).
Conclusion: Although trabeculoplasty laser is a good and safe treatment, it can make slight changes in the parameters of the anterior segment and macula.
