The first glaucoma drainage implant was developed in 1966. [2] Following on the success of the Molteno implant, several varieties of device have been developed from the original, the Baerveldt tube shunt, or the valved implants, such as the Ahmed glaucoma valve implant and the later generation pressure ridge Molteno implants.
Reoperation after failed trabeculectomy or tube shunt is very challenging. Trabectome surgery is a minimally invasive alternative to a repeat filter or shunt. Studies of patients undergoing trabectome surgery after a failed tube shunt have shown a statistically significant reduction in intraocular pressure after one year [42].
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...
George Baerveldt, M.B.Ch.B., was a Professor in the Department of Ophthalmology at the University of California, Irvine. Baerveldt developed [ 1 ] and held four patents related to the Baerveldt Glaucoma Implant , a device for the drainage of excess fluid from the eye in complex cases of glaucoma .

After two years researchers found that vision and quality of life are similar in both treatments. At the same time eye pressure was lower in people who underwent surgery and in the long-run surgery is more cost-effective. [114] [115] The LiGHT trial compared the effectiveness of eye drops and selective laser trabeculoplasty for open angle glaucoma.

Glaucoma in a dog. Canine glaucoma refers to a group of diseases in dogs that affect the optic nerve and involve a loss of retinal ganglion cells in a characteristic pattern. . An intraocular pressure greater than 22 mmHg (2.9 kPa) is a significant risk factor for the development of glauco
