Glaucoma is a group of eye diseases ... The baseline glaucoma evaluation tests include intraocular ... This coincides with clinical practice of LPI where an iridotomy ...
The contrast threshold values needed for perceiving this physiological effect are used in frequency doubling technology perimetry for the detection of even early phases of glaucoma. [ 4 ] [ 5 ] [ 6 ] A more recent study's results argue against the hypothesis that spatially nonlinear retinal ganglion cells are the physiological substrate of the ...
Glaucoma is currently the principal cause of irreversible blindness in the world. [1] Therefore, The Van Herick technique is pertinent to the interests of all eye care practitioners as it permits for a quick and simple screening alternative to the conventional Gonioscopy examination. [ 2 ]
Secondary glaucoma indicated after congenital cataract surgery is found between 6 and 24% of the cases noted, whereas, secondary glaucoma caused by primary IOL implantation was observed as 9.5%. [5] Additionally, for patients with aphakia and secondary IOL implantation, 15.1% of the cases were determined. [ 5 ]
Primary congenital glaucoma is a rare eye condition that is present at birth or develops early in childhood. It occurs due to improper drainage of the eye's fluids, which leads to increased pressure inside the eye, known as intraocular pressure .
The patient indicates whether he sees the light by pushing a button. The use of a white background and lights of incremental brightness is called "white-on-white" perimetry. This type of perimetry is the most commonly used in clinical practice, and in research trials where loss of visual field must be measured. [4]
The Maklakoff tonometer was an early example of this method, while the Goldmann tonometer is the most widely used version in current practice. [3] Because the probe makes contact with the cornea, a topical anesthetic , such as proxymetacaine , is introduced on to the surface of the eye in the form of an eye drop .
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 ...
