Comparison of gonioscopy and anterior segment optical coherence tomography in detecting angle closure in different quadrants of the anterior chamber angle
Intraocular lens position and anterior chamber angle
changes after cataract extraction in eyes with primary angle-closure glaucoma.
Assessing the anterior chamber angle
(ACA) is an important role for the optometrist.
Once the disease is suspected, it is relatively easy to confirm it by the examination of the anterior chamber angle
of the eye using gonioscopy and by checking the IOP.
14) used anterior segment OCT to investigate ACD and anterior chamber angle
in angle-closure glaucoma and open-angle glaucoma patients after cataract surgery and found that cases with narrow angles in particular showed larger reduction in IOP.
The mechanism of increased intraocular pressure appeared to be involvement of the anterior chamber angle
by solid tumor or loose seeding of tumor cells or bleeding in the anterior chamber, causing obstruction of aqueous outflow.
d) Taking measurements away from the limbus will overestimate the width of the anterior chamber angle
A recent study by AS-OCT showed that PEX eyes had significantly smaller anterior chamber angle
, shallower ACD, greater iris convexity and thinner irises than their fellow eyes and controls.
Axenfeld-Rieger syndrome is a bilateral, heterogeneous condition and may include developmental abnormalities in the anterior chamber angle
, iris, and trabecular meshwork.
Nanophthalmos: quantitative analysis of anterior chamber angle
configuration before and after cataract surgery.
Lens dislocated in the anterior chamber can mechanically obstruct the anterior chamber angle
Anterior chamber angle
supported lenses such as the Alcon Cachet lens
Evaluation of Scanning Protocols For Imaging The Anterior Chamber Angle
With Anterior Segment- Optical Coherence Tomography.
On gonioscopy the anterior chamber angle
from 3'O clock to 8'O clock was obscured rest of the angle was wide open.
For a more hands-on approach, Dr Dan Rosser led an introductory session which took practitioners through the basics of measuring the anterior chamber angle
, with a beginner's guide to gonioscopy.
