OCT and Retinal Scans

The eyes are the window to your soul, and the retina is the window to your health. The retina is the portion of light sensitive tissue at the back of the eye where the image you see is projected and relayed to your brain. Since it contains both nerve tissue and a rich vascular network, it also offers insight into many other health issues, which don’t only affect vision.

Using cutting edge technology, we are able to scan your retina and yield a three dimensional digital image that provides a wealth of information about your eye health, as well as systemic conditions. Furthermore, because the images are stored in a computer, they can be objectively compared to future exams to determine the progression of diseases or the success of treatments.

OCT (optical coherence tomography) scans and Digital Imaging Technology can detect changes or early signs of many diseases and conditions, like:

  • Glaucoma
  • Macular degeneration
  • Diabetes and diabetic retinopathy
  • Retinoblastoma
  • Ocular melanoma
  • Other tumors

Digital retinal imaging technology offers many advantages. The procedure is non invasive, painless, and quick. The high resolution 3D image provides details about your retina and the surface behind your eyes, in real time. The images give a picture of your current eye health and are stored to be used as a baseline to be compared to future evaluations.

OCT, Optical Coherence Tomography is an advanced scan, which can be compared to a CT scan since it analyzes the structural layers behind the eye, however it is similar to ultrasound technology in that it does not expose the patient to radiation. OCT scans use a laser to provide cross sectional images of the layers of the retina and optic nerve using light waves. This technology can help screen for early signs of glaucoma, diabetic retinopathy and macular degeneration and retinal detachment.

The test is relatively quick, and completely pain-free and non-invasive.

OPTOS Retinal Exam

The Optomap® retinal exam can play an important role in your eye exam. It provides a unique image of the back of your eye and allows your eye care professional to examine the health of your retina. The retina is the back portion of the eye, which detects light passed through your pupil, and relays it to the brain’s visual center through the optic nerve.

Oftentimes, at the beginning stages of an eye disease, there are no symptoms. In fact, once a patient has experienced vision loss from macular degeneration, glaucoma or diabetic retinopathy, the damage is often not reversible. On the other hand, if the disease is caught early – using technologically advanced tools like OPTOS – the progression of these ocular diseases can often be slowed down or stopped.

Here are some advantages of an Optomap® Retinal Exam:

  • Views the retina with more detail than other methods provide
  • Allows you to see the results for yourself, so you can discuss diagnosis knowledgeably
  • Detects eye health
  • Provides a baseline for future comparisons
  • Results are immediate
  • Test is not uncomfortable

Corneal Mapping

Corneal topography is a non-invasive way to map the surface of your eye’s cornea, which is the rounded outer surface that protects the colored iris and dark pupil. It’s also called videokeratography or photokeratoscopy. Due to its shape, the cornea plays a significant role in bending – or refracting – the light that enters your eye, so its shape also determines how clearly you see. Astigmatism is one example of corneal irregularity that is involved in refractive errors and your prescription depends on it.

Corneal mapping is essential to diagnosing and treating a number of conditions. For example, contact lens fittings for some kinds of contact lenses, like the ones that actually change the shape of your cornea, Ortho-K, rely on this 3D technique. Preparing for refractive surgery or LASIK and the follow-up appointment might also include corneal mapping.

Corneal topography is actually a development of a more basic corneal map, keratoscopy. The advanced technology makes use of computers to provide a detailed map of the entire cornea. Corneal mapping is quick and painless.

Visual Field Testing

When we see, we don’t just take in the object we are focusing on; rather visual information is gathered from the periphery as well, and that makes up the visual field. Testing the visual field measures your side vision in an easy, painless eye exam. The patient just keeps their head still on the chinrest, focuses on an object seen through a viewfinder, and presses a button when there is a flash of light. This machine is called a Humphrey. A similar test, called a Goldman visual field test, is conducted manually.

In addition to the role visual field testing plays in a comprehensive eye exam, many drivers’ license eye exams include a visual field test, because peripheral vision is essential for safe driving. Other uses include evaluating vision loss from ocular diseases like glaucoma, which affect eyesight in peripheral parts of the visual field.
