What is Glaukomflecken?
Glaukomflecken are small anterior subcapsular opacities secondary to lens epithelial necrosis resulting from acute angle closure glaucoma. These photographs from two different patients show central glaukomflecken and iris atrophy secondary to prior episodes of acute angle closure glaucoma.
Why is it called glaucoma?
The term “glaucoma” is derived from the ancient Greek glaukos (γλαυκóς), a nonspecific term connoting blue, green, or light gray. Although glaukos and related terms described the color of the pupil, there is some controversy regarding which of these colors was intended.
How does adrenaline treat glaucoma?
Adrenaline, the first nonselective agent to be used in glaucoma treatment, has a short half-life and causes vasodilation of the conjunctival blood vessels, resulting in eye redness.
What causes Buphthalmos?
Buphthalmos occurs most frequently due to primary congenital glaucoma. Other conditions which can cause raised IOP in early childhood, for example, Sturge-Weber syndrome, neurofibromatosis, aniridia, etc can also cause buphthalmos.
What vitamins are good for glaucoma?
Certain fruits and vegetables with higher vitamin A and C content have been shown to reduce glaucoma risk as well. Some of the most helpful fruits and vegetables for healthy vision are: collard greens, cabbage, kale, spinach, Brussels sprouts, celery, carrots, peaches, radishes, green beans, and beets.
Can glaucoma be fixed?
The damage caused by glaucoma can’t be reversed. But treatment and regular checkups can help slow or prevent vision loss, especially if you catch the disease in its early stages. Glaucoma is treated by lowering your eye pressure (intraocular pressure).
What is the action of adrenaline?
Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body’s metabolism, so as to maximise blood glucose levels (primarily for the brain).
What does adrenaline hormone do?
Adrenaline triggers the body’s fight-or-flight response. This reaction causes air passages to dilate to provide the muscles with the oxygen they need to either fight danger or flee. Adrenaline also triggers the blood vessels to contract to re-direct blood toward major muscle groups, including the heart and lungs.
What is Chalcosis?
Chalcosis or chalcosis bulbi refers to mild ocular inflammation due to an intraocular foreign body containing copper between about 70 to 85%.
