Abstract

Vision is so important in one’s life. But it is likely to be lost by various diseases. One such disease is called glaucoma. If the intraocular pressure in the eye exceeds 10-20 mm of hg, it may result in glaucoma. The front part of the eye is filled with a clear fluid called intraocular fluid or aqueous humor made by the ciliary body. The fluid flows out through the canal of schelmm whose diameter is of micrometer range. It is then absorbed into the blood stream through the eye’s drainage system. The inner pressure of the eye (intraocular pressure or IOP) depends upon the amount of fluid in the eye. In glaucoma, the drainage system remains open or closed causing the IOP to increase or decrease. The purpose of this paper is to overcome this disorder.a nanosensor is implanted in the eyes. A micro sized relay switch is placed at the opening of the canal of schelmm. The pressure in the eyes is detected by the nanosensor. If the pressure of the aqueous fluid exceeds 20 mm of hg, the relay switch is opened and the fluid is allowed to drain through the canal of schelmm. If the pressure is below 10mm of hg, the relay switch is closed, so that the fluid does not drain into the canal of schelmm. Thus the pressure is maintained constant. So the patient with glaucoma never loses his/her vision.
