Primary angle closure (PAC) encompasses a wide variety of conditions with different severity (narrow angles to severe glaucoma) and presentations (acute, subacute, and chronic). The evaluation of the anterior chamber (AC) angle is critical in diagnosis and treatment of PAC. Gonioscopy remains the gold standard diagnostic test, anterior segment OCT and ultrasound biomicroscopy (UBM) are also important diagnostic modalities in the evaluation of the AC angle. Laser peripheral iridotomy is the most common therapy for PAC. Due to the Eagle study and other studies, lens extraction with or without a glaucoma procedure (i.e. goniosynechiolysis, endocyclophotocoagulatio, or trabeculectomy) are becoming more popular and accepted for treatment of PAC.
