To compare the prevalence of angle closure among siblings of patients with open angles (OAs), suspect angle closure (PACS), and either primary angle closure (PAC) or PAC glaucoma (PACG).
To assess the immediate effect of laser peripheral iridotomy (LPI) and mechanisms of angle closure in a population-based study of primary angle closure (PAC) suspects.
We examined 7-week-old Vav2−/−Vav3−/− mice with non-elevated IOP who had either open angles or who displayed evidence of angle closure.
Over half of the Vav2/Vav3-deficient mice already showed evidence of angle closure by 7 weeks of age, increasing to nearly 80% in 12-week-old mice (Figure 4B).
There is also a link to the corresponding DCG classification page and the DynDom page for that domain movement which gives details on the residues comprising the domains, the location of the hinge axis, the hinge-bending residues, the angle of rotation, percentage closure, as well as many other details.
To determine the prevalence and determinants of angle closure in the Kandy District of central Sri Lanka.
Gonioscopy may show the presence of PAS causing variable degrees of angle closure and consequent intraocular pressure increase.
Nanophthalmos is traditionally associated with a high prevalence of angle closure glaucoma 1 13 and both nanophthalmos and primary angle closure glaucoma have similar ocular phenotypes including a short AL, shallow anterior chamber, hyperopia, small radius of corneal curvature and a thick crystalline lens.
Both chronic and acute closed-angle glaucomas present structural similarities: pupil-blocking force, status of angle synechia closure, and shallow depth of the anterior chamber; however, the former is asymptomatic, whereas the latter is symptomatic.
The inconsistent results are due to the definition of poor vision chosen by the authors (the BCVA cut-off ranged from ≤ 6/60 to < 3/60), the variability in the last follow up visit which was from six months to over six years, the ethnic differences of angle closure mechanism and the continuous improvement in the management of this disease.
Vav2−/−Vav3−/− mice with elevated IOP showed evidence of angle closure by histological analysis, while Vav2−/−Vav3−/− mice with non-elevated IOP displayed either open angles or evidence of early angle closure (PAS) and angle closure.
