Abstract
Background: Sequential Argon-Nd:YAG Laser iridotomy is effective and reduces complications, especially in patients with dark irides. A review of relevant studies comparing Nd:YAG Laser iridotomy with Sequential Argon-Nd:YAG Laser iridotomy has found that there are differences between studies in different populations (races).
Objective: To compare the outcomes between Nd:YAG Laser iridotomy and Sequential Nd:YAG Laser iridotomy for PACS patients in terms of visual acuity, changes in intraocular pressure, pain score, Iris haemorrhage and the duration of the procedure.
Method: The research design was a prospective experimental study. Data were collected from patients with primary angle closure suspects (PACS) who received services at the Division of Ophthalmology of Nopparat Rajathanee Hospital from January 1st, 2022, until July 1st, 2022.
Result: There was no statistically significant difference in Logmar Visual acuity change, intraocular pressure change (mmHg), or pain, but a statistically significant difference in iris hemorrhage. Iris haemorrhage in the Sequential Argon-Nd:YAG group was significantly lower (p-value 0.016), and it was found that the duration of the procedure in the Sequential Argon-Nd:YAG group was significantly greater than the Nd:YAG Laser group (p-value 0.007).
Conclusions: Sequential Argon-Nd:YAG has advantages over Nd:YAG Laser in patients with primary angle closure suspect and dark irides (Thais) because of less Iris haemorrhage, but the procedure duration is more prolonged.
