Glaucoma may be a contributory factor in the aetiology of retinal vein occlusion or may result from this condition. When glaucoma occurs secondary to retinal vein occlusion, it is usually considered to be due to vascularization of the anterior chamber angle and closure of the angle by goniosynechiae (Duke-Elder and Dobree, I967; Ballantyne and Michaelson, 1970). The two cases of retinal vein oc...

Purpose To report cases of glaucomatocyclitic crises and discuss the possibility of occurrence in patients with narrow or closed angles. Background The prevalence of angle closure is much higher among Asians than among the Western population. Currently, there is no evidence for a direct relationship between the etiology and angle structure. Design A retrospective and observational case seri...

OBJECTIVE To determine the association of changes in anterior chamber angle and anterior chamber depth (ACD) with intraocular pressure (IOP) reduction after uncomplicated phacoemulsification. METHODS In this prospective study, subjects underwent phacoemulsification with foldable lens implantation. Anterior chamber angle grading of 2 or less (Shaffer grading) in 3 or all quadrants was consider...

PURPOSE To assess efficacy of the Pentacam (PTC) and the anterior segment optical coherence tomography (AOCT) for detection of occludable angles. MATERIALS AND METHODS Fourty-one eyes with gonioscopically diagnosed occludable angles and 32 normal open-angle eyes were included. Anterior chamber angle (ACA) and anterior chamber depth (ACD) were measured with PTC and AOCT. Receiver operating cha...

PURPOSE To compare conventional laser peripheral iridotomy (LPI) and LPI combined with laser peripheral iridoplasty in eyes with primary angle closure suspect (PACS) by assessment of anterior chamber dimensional changes using a Pentacam. METHODS Forty-eight eyes of 24 subjects with bilateral PACS were recruited consecutively. Each eye was randomly allocated to treatment with conventional LPI,...

PURPOSE The iridocorneal angle in the mammalian eye including the trabecular meshwork (TM) develops from undifferentiated mesenchyme/neural crest between the iris root and cornea. The precise mechanisms underlying anterior angle development are unclear, and the contribution of cell death and phagocytic resorption by macrophages in angle development is controversial. In this study, we examined t...

PURPOSE To evaluate changes in anterior chamber (AC) morphology induced by cataract extraction using anterior segment optical coherence tomography (OCT). DESIGN Prospective comparative observational case series. METHODS Thirty-two eyes of 32 patients underwent OCT imaging of the angle before and after cataract surgery. Anterior chamber depth (ACD), angle opening distance at 500 microm (AOD(...
