“…Nonaka A et al 48 studied residual angle closure after iridotomy and found in 38.6% of eyes; this was confirmed functionally by the dark room prone position test and morphologically by UBM. They found that cataract surgery was effective to resolve completely the residual angle closure after iridotomy and lower IOP.…”

UBM is a high-frequency ultrasound technology that provides exceptionally detailed two-dimensional gray-scale images of the various anterior segment structures and evaluates them both quantitatively and qualitatively. It allows noninvasive in vivo imaging of structural details of the anterior ocular segment at near microscopic resolution and thus, there are many other applications of this new imaging method.This review outlines the uses of UBM in diagnosis and management of glaucoma.

“…Other studies had already demonstrated the improvement in anterior chamber parameters after cataract surgery [22][23][24][25][26] but this, to our knowledge, has the longest follow-up, demonstrating the stability of these changes, as well as their effect in IOP control.…”

“…Patients who underwent cataract surgery presented a 2.8 mmHg additional reduction in IOP with similar corneal endothelial cell counts as compared to patients who underwent LPI alone. Nonaka et al [23] reported that cataract surgery subsequent to laser iridotomy was also effective for complete resolution of residual angle closure, with concomitant control of IOP. Therefore, LPI with subsequent cataract surgery is also a feasible strategy to manage chronic angle closure.…”

Phacoemulsification versus peripheral iridotomy in the management of chronic primary angle closure: long-term follow-up

et al. 2014

Primary angle closure occurs as a result of crowded anterior segment anatomy, causing appositional contact between the peripheral iris and trabecular meshwork, thereby obstructing aqueous outflow. Several studies highlight the role of the crystalline lens in its pathogenesis. The objective of this work is to compare the long-term efficacy of phacoemulsification versus laser peripheral iridotomy (LPI) in the management of chronic primary angle closure (CPAC). Prospective case-control study with 30 eyes of 30 patients randomly divided in two groups: 15 eyes in the LPI group and 15 eyes in the IOL group. Patients in the LPI group underwent LPI using argon and Nd:YAG laser. Patients in the IOL group underwent phacoemulsification with posterior chamber intraocular lens (IOL) implantation. Examinations before and after the procedure included gonioscopy, Goldmann applanation tonometry, and anterior chamber evaluation using the Pentacam rotating Scheimpflug camera. The mean follow-up time was 31.13 ± 4.97 months. There was a statistically significant reduction in the intraocular pressure (IOP) and number of anti-glaucoma medications (p \ 0.01) only in the IOL group. Anterior chamber depth, angle, and volume were all higher in the IOL group (p \ 0.01) at the end of the follow-up period. Phacoemulsification with posterior chamber IOL implantation results in a higher anterior chamber depth, angle, and volume, when compared to LPI. Consequently, phacoemulsification has greater efficacy in lowering IOP and preventing its long-term increase in patients with CPAC and cataract.

“…19 Desse modo, a presença do mecanismo de não bloqueio pupilar após a realização da iridotomia vêm sendo sistematicamente relatado como um achado bem mais comum do que previamente se imaginava. 6,19,25,26 O componente da íris em plateau, baseado na interpretação subjetiva da presença de processo ciliar anteriorizado nas imagens da UBM, seria o mecanismo fisiopatogênico mais freqüente nesses casos. 6,19,25,26 Além disso, outros mecanismos de não bloqueio pupilar que não apresentam a típica configuração da íris em plateau (sem processos ciliares anteriorizados que dão sustentação à periferia iriana contra o trabeculado) estão sendo descritos em pacientes asiáticos.…”
