If the front chamber angle of the eye is too closed, there is a risk of acute increased pressure on the eye (acute glaucoma). This development occurs more in small eyes (hypermetropia) or if lens swelling occurs within the context of cataract formation.
This form of glaucoma, too, is more common in certain families.
Eye fundus examination is used to establish the extent to which the optic nerve shows a cavity. This can also be seen by taking photographs. Increasing cavity at successive visits is a sign of glaucoma.
- Eye pressure reading with non-contact or contact method.
- Field of vision examination or perimetry is done using a perimeter to trace premature blind zones long before the patient notices them himself or herself.
- Examination of the front chamber angle (gonioscopy) to establish which form of glaucoma is present.
- Examination of the cornea thickness (pachymetry) as a correction factor for the recorded eye pressure reading.
- Examination of the front chamber (angle): ‘Scheimpflug’ analysis.
What is the treatment?
Medication (eye collyres), laser (yag iridotomy), surgery (iridectomy or lens extraction).
