Equipment



The Department of Ophthalmology offers state-of the art technology for research and clinical applications.

A well-equipped cell culture laboratory was established in the new medical research facility and operates with the continuing support of the Ohio Lions Eye Research Foundation. Currently, trabecular meshwork endothelial cells are harvested and grown in this lab for use in a custom-designed flow system for testing cellular response to treatments for glaucoma.

Electroretinogram (ERG)

Electroretinography measures the electrical responses of various cell types in the retina, including the photoreceptors (rods and cones), inner retinal cells (bipolar and amacrine cells), and the ganglion cells. Electrodes are usually placed on the cornea and the skin near the eye, although it is possible to record the ERG from skin electrodes.


Optos Ultra-Widefield Imaging

Optos introduced retinal imaging with ultra-widefield scanning laser technology to support practitioners diagnosing, analyzing, documenting and monitoring ocular pathology that may first present in the periphery, and otherwise may go undetected using traditional examination techniques and equipment. Several ultra-widefield high resolution imaging devices are available with simultaneous non-contact pole-to-periphery views of more than 80% or 200 degrees of the retina in a single capture.


Heidelberg Retina Tomograph (HRT)

The HRT is superior to other optic nerve head analyzers for accuracy in 3-dimensional optic nerve head topography. The HRT uses scanning laser tomography to produce the 3-dimensional image, which allow precise measurements of the optic nerve head parameters. This technology enhances the probability of differentiating between normal eyes and glaucomatous eyes even before visual field defects are present. The optic CUP, RIM and RNFL assessment are essential elements of detecting and assessing the damage caused by glaucoma. The advanced imaging of the HRT is proven to measure all three elements and to detect glaucoma at a better level than stereo fundus photography with expert interpretation.


Fundus Retinal Photography

A fundus camera or retinal camera is a specialized low power microscope with an attached camera designed for fundus photography, that is, creating a photograph of the interior surface of the eye, including the retina, optic disc, macula, and posterior pole (i.e. the fundus).


Optical Coherence Tomography (OCT)

The OCT3 is being used to diagnose and monitor optic nerve disorders by determining the degree of retinal ganglion cell-axonal loss resulting in thinning of the retinal nerve fiber layer. Thinning is monitored most frequently in glaucoma, since there are a number of patients with early glaucoma who have normal visual field results, but pathologic thinning of the retinal nerve fiber layer, compared to age-matched normals. The OCT3 works much like an ultrasound, except that it uses light rather than sound and thereby achieves ten times better resolution. A typical test takes less than 10 minutes making it possible for everyone to undergo a rigorous retinal screening without discomfort.


8 Tesla Magnetic Resonance Imaging (MRI)

The world's first 8 Tesla human MRI scanner was assembled at The Ohio State University Medical Center. Developed by an Ohio State University physicist, this scanner uses the world’s most powerful magnet. The 8 Tesla is currently the most powerful human MRI in the world. It has field strength of eight, more than seven times greater than the usual 1.5 Tesla MRI scanners. The images that are produce show superior contrast and spatial resolution resulting in better diagnosis and treatment.


YAG Laser

A YAG Laser is used to remove the haze of a membrane situated behind the intraocular lens (IOL) that can develop after cataract surgery. Usually the patient's eye is dilated before the procedure. The procedure only takes a few minutes and is completely painless. Following the procedure there is no discomfort and most ophthalmologists will recommend an anti-inflammatory eye drop medication. Most patients may expect their vision to improve within a day following the procedure and may resume normal activities immediately. Patients should anticipate some “floaters” following this procedure, however, these will likely resolve within a few weeks.


Coherent Novus Omni Diode Laser

A Diode Laser is used to treat glaucoma. It is an outpatient procedure that is done in the office. The eye is anesthetized, and a laser probe, which looks like a small pen, is then placed on the eye, just peripheral to the iris. The laser energy is directed into the eye towards the ciliary body, which is partially destroyed. The whole procedure takes only a minute or two. Most people experience only minor discomfort during the procedure. Some patients may experience blurry vision or slight discomfort, but this tends to resolve within a few days. Follow-up visits are scheduled for the day after the procedure and the following week. This procedure is intended to reduce the amount of fluid produced in the eye thus decreasing the need for glaucoma eye drops.
