Visual Fields

visualfieldsA Visual Fields test subjects a Patient to no physical discomfort, but sit comfortably! This test may take some time to complete.

A Patient stares at a central target in a concave dome. A computer program projects a point of light at a location on the dome’s surface. If the Patient can see the point of light, they press a button on a handheld control.

The magic: Each point of light the computer projects on the dome’s surface corresponds to somewhere within a Patient’s ideal field of view. How wide — or narrow — the Patient’s field of view really is, is what the computer and visual fields test helps to determine.

Slit Lamp

slitlampThe Slit lamp is an instrument consisting of a high-intensity light source that can be focused to shine as a slit. It is used in conjunction with a microscope. The lamp facilitates an examination which looks at anterior segment of the human eye, which includes the eyelid, sclera, conjunctiva, iris, natural crystalline lens, and cornea.

The binocular slit-lamp examination provides a stereoscopic magnified view of the eye structures in striking detail, enabling exact anatomical diagnoses to be made for a variety of eye conditions, such as cataracts, corneal injuries, keratoconus, macular degeneration, presbyopia and retinal detachment.

Corneal Topography

mmapper-01Magellan MapperCorneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye.
mmapper-02Magellan MapperMultiple light concentric rings are projected on to the cornea. The reflected image is captured on a charge-coupled device (CCD) camera. Computer software analyzes the data and displays the results in various formats.
mmapper-03Since the cornea is normally responsible for some 70% of the eye’s refractive power, its topology is of critical importance in determining the quality of vision. The three-dimensional map is therefore a valuable aid to the examining Ophthalmologist or Optometrist.

Retinal Imaging

cr-dgi-01Retinal Imaging: the CR-DGi uses a combination of optics designed specifically for retinal imaging and Canon’s renowned SLR digital camera technology. As a result, we are able to capture extremely refined images of the retina for detecting or monitoring diabetes, glaucoma, and other serious conditions.

The CR-DGi captures images that can be viewed immediately, making procedures more efficient. Because the images are digital, they can be used with many different applications, such as telemedicine and electronic filing.

Optical Coherance Tomography

octOptical coherence tomography (OCT) of the cornea and anterior segment is an optical method of cross-sectional scanning based on reflection and scattering of light from the structures within the cornea. Measuring different reflectivity from structures within the cornea by a method of optical interferometry produces the cross-section image of the cornea and other anterior segment structures.
