“…YAG-laser iridotomy is considered the definitive treatment to reach the goal in case of acute PAC with pupillary block and can be performed as soon as the cornea is clear. Changes in anterior segment morphology such as a wider angle have been demonstrated in more than one study using UBM and AS-OCT (Gazzard et al, 2003b;How et al, 2012). Laser iridotomy could not be completely curative in angle closure or could not ensure a long-term efficacy, especially if different mechanisms are the basis of the acute attack .…”

The acute primary angle closure is an ophthalmological urgency which requires immediate treatment to prevent permanent damaged.The population studies reveal that more than a half of predispose individuals will not manifest the disease. This reality, the cost of laser prophylactic treatment, the risk of ocular complications and the low accessibility to the technology in some populations justify that proper investigations go on to define the morphological and/or functional factors that determine the acute presentation of the disease [1].The optical coherence tomography is a high resolution, non invasive technology that offers the possibility to

show abstract

“…Our study of static biometric findings before and after LPI, which showed that PD, lens vault, and anterior chamber depth did not change after LPI but that AOD 500 and trabecular-iris space area at 500 m from the scleral spur increased considerably, is consistent with previous studies. 17,28,[30][31][32][33] Therefore, LPI results in significant widening of the angle but without changes in the anterior segment dimensions.…”

“…23 Laser peripheral iridotomy is the recommended first-line treatment in the management of PACG. [24][25][26][27] After LPI, changes in morphologic anterior chamber angle in PACG eyes have been described in several studies 13,17,28 using ultrasonographic biomicroscopy and ASOCT. Although these anatomical characteristics were evaluated on 2-dimensional static images, dynamic changes have not been studied to date.…”
