Retinal photography

A retinal photograph is a detailed image of the back of the eye. The photograph creates a visual record of your current eye health and will allow your optometrist to do a direct comparison from one year to the next, monitoring changes over time.

At QOC, we recommend retinal photographs annually, although they may be required more frequently for patients diagnosed with diabetes, macular degeneration, or other diseases of the eye.

Optical Coherence Tomography (OCT)

The OCT is a noninvasive imaging test that uses light waves to take crosssection pictures of your retina, the lightsensitive tissue lining the back of the eye.

Each of the retina’s distinctive layers can be seen, allowing your optometrist to map and measure their thickness. These measurements help with early detection, diagnosis and treatment guidance for retinal diseases and conditions, including age related macular degeneration, diabetic eye disease, and glaucoma.

At QOC, your optometrist will recommend OCT imaging when required to best monitor your eye health.

Pachymetry

Pachymetry is the measurement of corneal thickness and is accomplished using a digital ultrasound instrument. Pachymetry is important for determining candidacy for laser eye surgery and in glaucoma diagnosis.

Visual Field Assessments

A visual field is the measurement of the sensitivity of peripheral vision. This is used most commonly for diagnosing glaucoma, but is also used after a stroke, for optic nerve disease, or any conditions affecting the visual pathway to the brain.
