MEDICAL PROCEDURES
IRIDECTOMY:
Surgical procedure that involves partial removal of the iris. This technique is usually implemented when it is necessary to reduce the ocular pressure, enlarge an abnormally small pupil, or remove cataracts or a tumor. In patients with acute glaucoma, the surgery is performed with laser because it allows an extremely precise operation.
YAG CAPSULOTOMY
Outpatient procedure performed in patients who have previously undergone cataract surgery. Over time, residual cells may produce an epithelial layer after surgery, resulting in posterior capsular opacification of the eye and diminishing sight. In these cases, the growth can be corrected by laser surgery following an individualised assessment. In this case, the YAG type (most common for this procedure) is used. The laser beam is applied to the intraocular lens where an opening in made after dilating the pupil.
OCT
Optical coherence tomography (OCT) is one of the most modern and revolutionary techniques in ophthalmology available to achieve an accurate diagnosis of the interior of the eye. As its name indicates, the procedure consists of using a special apparatus to obtain information on the structure and shape of the various segments of the eyeball through two-dimensional images. At the present time, two types of apparatus can be used to carry out these kinds of tests/visualisations: one for retinal and optic nerve imaging (posterior pole), and another for corneal and lens imaging (anterior segment). The IOC is equipped with diagnostic apparatus for the optic nerve, macular area and corneal area.
ELECTROPHYSIOLOGICAL TESTS
A number of electrophysiology tests can be used to detect or diagnose potential retina or optic nerve disease. These examinations are performed using various visual stimuli that activate the segments being assessed, as projection of the stimuli will produce a response or reaction. The information is then evaluated to confirm the presence or absence of functional abnormalities in the eye.
Types of tests performed at the IOC:- VEP (visual evoked potentials)
- EOG (electro-oculogram)
- ERG (electroretinogram)
