to treat glaucoma and corneal neovascularization two of the world s leading eye diseases. The microneedles range in length from 400 to 700 microns
Glaucoma affects about 2. 2 million people in the United states and is the second leading cause of blindness worldwide.
Glaucoma results from elevated pressure inside the eye that can be treated by reducing production of the aqueous humor fluid in the eye increasing flow of the fluid from the eye or both.
Glaucoma is controlled now by the use of eye drops which must be applied daily. Studies show that as few as 56 percent of glaucoma patients follow the therapy protocol.
The first study shows that the microneedle therapy would inject drugs into space between two layers of the eye near the ciliary body
##The ultimate goal for us would be for glaucoma patients visiting the doctor to get an injection that would last for the next six months until the next time the patient needed to see the doctor##Prausnitz says.##
##If we can do away with the need for patients to use eye drops we could potentially have better control of intraocular pressure and better treatment of glaucoma.##
For the glaucoma drug for instance the needle is only about half a millimeter long which is long enough to penetrate through the sclera the outer layer of the eye to the supraciliary space.
#Electronic eye sensor watches out for glaucoma Researchers have designed a high-tech, low-power sensor that can be placed permanently in a person eye to track hard-to-measure changes in pressure
and monitor for diseases like glaucoma. The sensor would be embedded with an artificial lens during cataract surgery
The research team wanted to find an easy way to measure eye pressure for management of glaucoma,
At most, patients at risk for glaucoma may only get their pressure checked several times a year,
This increased intraocular pressure is the main factor in glaucoma, which causes vision loss and ultimately blindness. ftentimes damage to vision is noticed late in the game,
by the time they are diagnosed with glaucoma, Shen says. r, if medications are given, there no consistent way to check their effectiveness.
Both cataracts and glaucoma affect a similar aging population so it seems a natural pairing to place a pressure monitoring device in a new lens during cataract surgery.

System gives hope to those blinded by a rare genetic eye condition called advanced retinitis pigmentosa, which damages the light-sensitive cells that line the retina.

In people with a disease called retinitis pigmentosa, cones slowly atrophy, eventually causing blindness. Friedrich Miescher Institute scientists Botond Roska and Volker Busskamp have shown previously that some vision can be restored in mice by engineering those cone cells to express light-sensitive proteins.
making it potentially more useful for treating retinitis pigmentosa. This type of noninvasive approach to optogenetics could also represent a step toward developing optogenetic treatments for diseases such as epilepsy,
An encouraging new study published in Nano Letters describes a revolutionary novel device tested on animal-derived retinal models that has the potential to treat a number of eye diseases.
Their eyes have caused defects largely by refractive errors, cataract, or glaucoma. They don see the world as the rest of the seeing world does and, due to the high costs of healthcare or unavailability of medical facilities,
#Spot Glaucoma With Your Smartphone Researchers from the Indian Institute of Science, Bangalore, have developed a method to diagnose glaucoma from smartphone images.
Scientists at the Indian Institute of Science (IISC), Bangalore, have announced the development of a new and simple method to detect glaucoma early enough to prevent blindness.
Glaucoma is usually the result of increased pressure in the eye, resulting in damage to the optic nerve,
which carries information to the brain. Since the symptoms of glaucoma do not show up until very late stages,
early detection by a procedure called fundus imaging is advised. Fundus imaging involves taking photographs of the retina
professor of electrical engineering at the IISC and leader of the team that developed the new method. his pre-screening tool can detect glaucoma with 90 percent accuracy,
Net that currently available technologies for detection of glaucoma are expensive while the new method is not only cheap,
but will also help with mass-screening for glaucoma. About 12 percent of India 1. 2 billion people are estimated to be affected by glaucoma. amage to the optic nerve due to glaucoma is not reversible.
If we detect it early then it is possible to halt the progression of glaucoma by appropriate medications or surgery,
Pakrasi says. ision may be preserved at nearly normal levels if glaucoma is detected and treated early. c

Glaucoma is a neurodegenerative disease where patients lose seemingly random patches of vision in each eye.
Scientists have thought long that glaucoma progression is independent of or uncontrolled by the brain. Last year
researchers found evidence that the progression of glaucoma is not random and that the brain may be involved after all.
Specifically, they found patients with moderate to severe glaucoma maintained vision in one eye where it was lost in the other like two puzzle pieces fitting together (a igsaw Effect. his suggests some communication between the eyes must be going on
Sponsel and his research team found that the Jigsaw Effect begins at the earliest stages of glaucoma and discovered clues as to
which part of the brain is responsible for optimizing vision in the face of glaucoma slow destruction of sight.
which challenge longstanding assumptions about glaucoma, have been met with skepticism. Other glaucoma experts challenged the results in a letter to the TVST editor. f the brain controls the distribution of vision loss in glaucoma,
then a patient vision with their two eyes should be better than if you simply ix and matchthe vision of right and left eyes from different patients,
their letter analyzed a new cohort of glaucoma patients in which hat essentially what we did.
which have neurodegenerative biology similar to glaucoma, may also be mediated actively by the brain. ur work has illustrated that the brain will not let us lose control of the same function on both sides of the brain

Refined data analysis of paired Matrix visual fields confirms the existence of a natural optimization of binocular visual function in severe bilateral glaucoma via interlocking fields that could only be created by CNS involvement.
The paired eyes and brain are reaffirmed to function as a unified system in the progressive age-related neurodegenerative condition chronic open angle glaucoma,
