This project will develop a technique for detecting blind spots in the human field of vision by using virtual reality goggles to present a stimulus to the eye and then recording the tiny electrical signals from the brain that are generated in response to this. It will overcome many of the limitations of current subjective visual field testing and expand the potential market for the objective perimeter that we have developed.

It will overcome many of the limitations of current subjective visual field testing and expand the potential market for the objective perimeter that we have developed. By recording from both eyes simultaneously it will halve the recording time and improve the ability to do inter-eye comparisons to look for early signs of glaucoma.Read moreRead less
A ROBOTIC MICRO DRAINAGE SURGERY FOR GLAUCOMA (A BIOLOGICAL MICROFISTULA AND IMPLANTATION METHOD AND APPARATUS)

Summary
Glaucoma is a major cause of blindness in our community. We are developing a new surgical procedure to treat glaucoma. The technique is based on the implantation of a tiny drainage tube inside the eye. This allows the eye's natural fluid to escape at the required rate. Insufficient drainage, or over production of fluid in the eye's of glaucoma patients is responsible for the high pressures inside the eye that characterise this disease. A simple, safe, and reliable surgical procedure to lower int ....Glaucoma is a major cause of blindness in our community. We are developing a new surgical procedure to treat glaucoma.

Insufficient drainage, or over production of fluid in the eye's of glaucoma patients is responsible for the high pressures inside the eye that characterise this disease. A simple, safe, and reliable surgical procedure to lower intraocular pressure would be a major benefit to the almost 67 million glaucoma patients worldwide, and would relieve the current need for lifelong medication.Read moreRead less

Summary
Glaucoma is a major cause of blindness in our community. The biggest risk factor for glaucoma is raised intraocular pressure. However, the exact cause of the disease remains unknown. Through our basic science studies in animals we have discovered that changes in blood flow in the vessels at the optic disk may be involved in the disease process.

The biggest risk factor for glaucoma is raised intraocular pressure. However, the exact cause of the disease remains unknown. Through our basic science studies in animals we have discovered that changes in blood flow in the vessels at the optic disk may be involved in the disease process. In recent clinical trials we discovered that the presence or absence of pulsations in the retinal veins at the disk was both an indicator of severity and progression of glaucoma. This is a major breakthrough because there is no other means of predicting in which glaucoma patients vision loss will develop most rapidly. This information will be very helpful in deciding which patients should have the most agressive treatment to restore normal intraocular pressure. This project seeks to develop a new commercial device to make such an examination easy for any clinical ophthalmologist. The device allows the doctor to examine the vessels at the disk whilst applying slight pressure to the eye to temporarily raise intraocular pressure. A footswitch is pressed when the doctor sees the vessels pulsate. The required force is recorded by a laptop computer and the data stored along with the patients details. Now we have confirmed the ability of such a measurement to predict the rate of visual field loss in glaucoma, such a measurement will become much more widespread in clinical ophthalmology, offering a new and large scale opportunity for such instrumentation. Our device will be easy to operate, more comfortable for the patient, and will be of major diagnostic value in glaucoma clinics worldwide.Read moreRead less
