Visual field testing provides with essential information about the diagnosis and progress of blindness causing diseases. Visual field testing is a primary tool in the diagnosis and monitoring of glaucoma.

When we do a visual field analysis we are testing the light sensitivity of the peripheral portions of the retina and the peripheral visual field. Abnormalities in the visual field may indicate optic nerve disease, multiple sclerosis, brain tumor in addition to many other neurological and systematic diseases.

We utilize the Computerized Visual Field Analyzer. This instrument has become the standard in the world for visual field testing.


A-scan ultrasound biometry, commonly referred to as an A-scan, is routine type of diagnostic test used in ophthalmology. The A-scan provides data on the length of the eye, which is a major determinant in common sight disorders. The most common use of the A-scan is to determine eye length for calculation of intraocular lens power. The other major use of the A-scan is to determine the size and ultrasound characteristics of masses in the eye, in order to determine the type of mass. This is often termed quantitative A-scan.


Sometimes after cataract surgery a thin membrane develops behind the intraocular lens implant. This is not a new cataract and can easily be dissolved with the aid of a YAG laser.

YAG lasers are used for peripheral iridotomy in patients with acute angle-closure glaucoma, where it has superseded surgical iridectomy. Frequency-doubled Nd:YAG lasers (wavelength 532 nm) are used for pan-retinal photocoagulation in patients with diabetic retinopathy
