What does trabecular thickening mean?
Thickening of the trabecular means that the iliac crest has thickened over time. Studies have shown this is common in older women due to age, or trauma.
What is the correct direction of aqueous humor flow?
The flow of the aqueous humor flows in the following manner: 1) Ciliary body --> Posterior Chamber 2) Posterior Chamber --> Anterior Chamber 3) Anterior chamber --> Canal of Schlemm Aqueous humour is produced behind the iris by the ciliary body. It flows through the pupil and drains away at the angle between the cornea and iris (the drainage angle). Within the drainage angle, the aqueous humour passes through a porous tissue - the trabecular meshwork - into a collector channel (Schlemm's canal), which empties into veins under the conjunctiva and thus back into the bloodstream. Most of the aqueous humour leaves the eye through the trabecular meshwork. This is called the conventional outflow pathway. There is however another "pathway" if you wish; some aqueous humour also leaves the eye through the ciliary body. This is called the uveo-scleral or non-conventional outflow pathway.
What is the function of corneal scissors?
corneal scissors are used as follows: 1). to enlarge the corneal and corneoscleral incision in cataract surgery and keratoplasty. 2). trabeculectomy (cutting trabecular tissues)
Wards's triangle concerning the trabecule and femoral neck?
The medical definition of the Wards triangle is "an area of diminished density in the trabecular pattern of the neck of the femur evident by x-ray. If the hips have a healthy density and the femur neck score is exceptionally low (or strikingly different than the previous score) then the technician may have reported density of the Wards Triangle.
If a researcher was interested in slowing down the movement of amoebas by disrupting their cell membranes which protein filaments should she be studying?
Considering that Amoeba sp., among other animal cells, possesses the capacity of dynamic surface extensions containing actin filaments. These filaments produce pseudopodia-stubby distensions of the actin cortex-with which they walked over surfaces. Therefore if there is an interest in slowing down the movement we would have to be interested in fibroblast cells that regularly extend a thin, sheetlike process known as lamellipodium, which contains a dense meshwork of actin filaments. Moreover, actin filaments can form the so-called microspikes, which are about 0.1 um wide and 5 to 10 um long and contain a loose bundle of about 20 actin filaments oriented with their plus ends pointing outward. In conclusion, it will be a good idea to look at the actin protein in order to make a research in amoeba's locomotion processes.
Does the trabecular meshwork become blocked in closed-angle glaucoma?
Nope, Only in Open-Angel Glaucoma
What causes angle closure in the eye?
An angle closure occurs when ocular anomalies (abnormalities) temporarily or permanently block the trabecular meshwork,
Is Aqueous fluid is drained through the canal of Schlemn?
yes. it is constantly filtered and drained through the trabecular meshwork and the canal of schlemm.
What is used to treat open-angle glaucoma by creating openings in the trabecular meshwork to allow fluid to drain properly?
Laser Trabeculoplasty
What is plateau iris?
The irises of individuals with plateau iris is bunched up in the anterior chamber, and it is malpositioned along the trabecular meshwork.
What procedure is performed before having a goniotomy?
Before the surgeon begins the procedure, the patient is given miotics, which are drugs that cause the pupil to contract. This partial closure improves the surgeon's view of and access to the trabecular meshwork;
What drains the aqueous humor from eye?
Ciliary body ---posterior chamber-pupil---anterior chamber---anterior chamber angle---trabecular meshwork---canal of Schlemm-collector channels
What has the author Adolfs Zorgevics written?
Taras Juzkiw has written: 'Biomechanical testing of human trabecular meshwork cells and Schlemm's canal endothelial cells'
Can blows to the head cause glaucoma?
Technically it is possible, but very unlikely. They type of Glaucoma would be Pigmentary glaucoma which can be (it is thought) caused by pigment granules being broken off from the iris and being deposited in the trabecular meshwork. This is technically possible, but so is winning the lottery and I'd expect to win the lottery before this happening...
