Examination of the anterior chamber angle
is an important part of diagnosing and managing several ocular conditions.
Treatment is by surgical opening of the anterior chamber angle
and IPO lowering drugs.
The anterior OCT scan allows visualisation of the anterior chamber angle
and also provides measurements of corneal thickness, allowing the diagnosis of narrow angles and keratoconus.
The angular separation seen at the limbal corneal junction is an estimation of the anterior chamber angle
depth in degrees (Figure 5 and Table 2).
However, in this condition there is no photophobia or corneal swelling, no break in Descemet's membrane, no abnormality detectable in the anterior chamber angle
, no cupping of the optic disc, and no significant increase in IOP.
Practical tools enable detailed planning and measurement of anterior segment structures, including anterior chamber depth (ACD), anterior chamber angles
and the angle-to-angle distance (anterior chamber diameter).
