Glaucoma is a common diagnosis that refers to a condition of the optic nerve located in the back of the eye. The optic nerve is responsible for transmitting information from the retina to the brain. In patients with glaucoma, the optic nerve degenerates in a characteristic pattern that is related to the pressure inside the eye. This pattern causes a loss of peripheral, or side, vision first. Undiagnosed and untreated, glaucoma is an irreversible, blinding disease. We are proud to offer the latest technology to detect and manage glaucoma.
Visual Field Testing
In order to test and measure the peripheral or side vision, a visual field test is performed. This is a sophisticated computerized evaluation of the function of the optic nerve. The visual field test can detect loss of peripheral vision before it is noticed by patients. Visual field tests are also performed in a serial fashion, year to year, to monitor patients with glaucoma. Visual fields are also utilized to measure field loss from droopy eyelids (ptosis), diseases of the optic nerve and visual pathways, and macular disease.
OCT (Optical Coherence Tomography)
The OCT test analyzes and measures the anatomy of the optic nerve. It is also useful in the diagnosis and monitoring of glaucoma. OCT tests are compared to visual fields to look for a correlation of structure to function of the optic nerve. An OCT can also be looked at in a serial fashion to look for progression indicative of glaucoma.
High resolution digital photography documents the anatomy of the optic nerve. Images can be magnified and enhanced. Stereo images are also used to capture a three dimensional picture of the optic nerve. Digital photography can establish a baseline for patients that are being watched carefully for the development of glaucoma (glaucoma suspects). We also use digital photography in patients with advanced glaucoma to look for subtle changes in the optic nerve.
