purpose: to compare anterior segment and ocular biometric parameters of unaffected fellow eyes of patients with a previous attack of acute angle closure (aac), primary angle closure suspect (pacs) eyes, and normal eyes; and to assess the risk of developing aac in pacs. methods: in this prospective comparative observational case series, 16 unaffected fellow eyes of patients with a previous attac...

purpose: to evaluate changes in anterior chamber (ac) parameters before and one month after nd:yag capsulotomy. methods: a total of 30 eyes from 27 patients with posterior capsule opacification graded 2-4 with surgical history of uneventful phacoemulsification and acrylic foldable iol implantation were included in this study. before capsulotomy and one month later, anterior chamber depth, volum...

PURPOSE To evaluate the association between baseline angle width and laser peripheral iridotomy (LPI)-induced opening of the anterior chamber angle. METHODS Anterior segment optical coherence tomography images captured before and after LPI were analyzed to determine the angle opening distance at 250 μm (AOD250), 500 μm (AOD500), and 750 μm (AOD750) from the scleral spur; trabecular-iris space...

background: it has been estimated that 67 million people worldwide are affected with a primary glaucoma and that one-third have primary angle closure glaucoma. we aimed to determine the biometric differences between the eyes of patients with acute attack of primary angle closure and their non-involved fellow eyes.   methods: twenty eight patients with acute attack of primary angle closure were ...

The anterior chamber angle is the actual anatomical angle created by the root of the iris and the peripheral corneal vault. Within it lie the structures involved in the outflow passage of the aqueous, namely the trabecular meshwork and the Schlemm’s canal (figure 1). The depth of the angle in a healthy eye is approximately 30°, with the superior part usually less deep than the inferior half. Ho...

PURPOSE Scheimpflug imaging allows quantitative analysis of the width of the anterior chamber angle. We report the population-based distribution of the anterior chamber angle width using this noncontact imaging technique and investigate associated factors. METHODS A population-based cross-sectional study was carried out in Germany. A comprehensive ophthalmologic examination including refracti...

Background: It has been estimated that 67 million people worldwide are affected with a primary glaucoma and that one-third have primary angle closure glaucoma. We aimed to determine the biometric differences between the eyes of patients with acute attack of primary angle closure and their non-involved fellow eyes. Methods: Twenty eight patients with acute attack of primary angle closure were re...

Primary angle-closure glaucoma (PACG) is a major form of glaucoma in Asia. It is a leading cause of blindness worldwide. Laser peripheral iridotomy (LPI) is the standard firstline intervention in both acute and chronic forms. It is successful in preventing recurrence of acute attacks and virtually eliminates the risk of an acute attack in the fellow eye. Peripheral iridotomy eliminates pupillar...

AIM To assess the value of slit lamp adapted optical coherence tomography (OCT) for the management of malignant glaucoma following filtration surgery. METHODS Two patients (three eyes) developed malignant glaucoma following filtration surgery for primary open angle glaucoma (POAG). With slit lamp adapted OCT it was possible to image non-invasively the anterior chamber angle structures during ...
