The Eye and Glaucoma Biology Essay
Quoted, viewed. Abstract. Glaucoma is an insidious group of eye diseases that cause optic nerve degeneration, progressive vision loss and irreversible blindness. The number of. Behind the anterior chamber is the iris of the eye, the colored part of the eye, and the dark hole in the center is called the pupil. Muscles in the iris dilate, dilate, or constrict the pupil to control its size. Glaucoma is one of the leading causes of irreversible blindness worldwide. Although intraocular pressure IOP represents an important risk factor, the underlying pathophysiology still remains largely unclear. The correlation between vascular abnormalities and glaucoma has been considered for decades. Evidence for a role that vascular factors play in congenital glaucoma. Congenital glaucoma is a genetically heterogeneous condition that is usually apparent at birth but may remain undiagnosed until the patient's age. Due to the flexibility of the sclera in infants, the increase in intraocular pressure associated with this condition causes buphthalmos. How the eyes work. All the different parts of your eyes work together to help you see. First the light passes through the cornea, the clear front layer of the eye. The cornea is shaped like a dome and bends light to help the eye focus. Some of this light enters the eye through an opening called the pupil PYOO-pul. Glaucoma is a group of eye diseases that can cause vision loss and blindness by damaging the nerve at the back of your eye, the optic nerve. Experts aren't sure what causes the most common forms of glaucoma, but people with high eye pressure are at greater risk for glaucoma. Your ophthalmologist can check for glaucoma. A biology essay is a type of academic paper that focuses on a particular topic of biology. It can discuss animal life, cycles in biology or a botanical topic. You must demonstrate your critical thinking skills and provide relevant evidence to support your perspective. On this page you will find examples of biology essays.
