Special Testing

Additional Tests include:

Color Vision – to detect type and extent of any color vision deficiency

Depth Perception – to determine the ability to see in 3D and perceive the distance of an object

OCT (Optical Coherence Tomography) – non-invasive optical signal method to obtain high resolution 3-D images within and posterior to the retina and optic nerve, very useful in the diagnosis and management of conditions such as glaucoma, diabetic retinopathy, and macular degeneration

Posterior or Anterior Segment Digital Photography - detailed digital images of the back or front of the eye useful in the management of conditions such as glaucoma, diabetic retinopathy, and macular degeneration

A-Scan Ultrasound – to determine the length of the eye for calculation of the intraocular lens implant used after removing a cataract

Keratometry – to measure the curvature of the cornea to help select proper contact lens or intraocular lens implant

Automated Perimetry (Visual Field Testing) – use of a computer-based program to detect defects in the field of vision that may indicate conditions affecting the visual pathway from the back of the eye to the back of the brain such as glaucoma, brain tumors, and strokes

Gonioscopy – use of a gonio lens and a slit lamp microscope to view the area between the cornea and iris to diagnose and monitor various eye conditions including glaucoma

Pachymetry – to measure the thickness of the cornea using ultrasound, an important test for glaucoma detection
