Track: Optometry:

Optometry is a health care profession which involves examining the eyes and applicable visual systems for defects or abnormalities as well as the medical diagnosis and management of eye disease. Traditionally, the field of optometry began with the primary focus of correcting refractive error through the use of spectacles. Modern day optometry, however, has evolved through time so that the education curriculum additionally includes intensive medical training in the diagnosis and management of ocular disease in countries where the profession is established and regulated. Optometrists (also known as Doctors of Optometry in the US and Canada for those holding the O.D. degreeor Ophthalmic Opticians in the UK are medical professionals who provide primary eye care through comprehensive eye examinations to detect and treat various visual abnormalities and eye diseases. Being a regulated profession, an optometrist's scope of practice may differ depending on the location. Thus, disorders or diseases detected outside the treatment scope of optometry are referred out to relevant medical professionals for proper care, more commonly to ophthalmologists who are physicians that specialize in tertiary medical and surgical care of the eye. Optometrists typically work closely together with other eye care professionals such as ophthalmologists and opticians to deliver quality and efficient eye care to the general public.

Track: 1: Glaucoma:

Glaucoma is a confused ailment in which harm to the optic nerve prompts dynamic, irreversible vision misfortune. Glaucoma is the second driving reason for visual impairment. Glaucoma is an illness of the eye in which liquid weight inside the eye rises - if left untreated the patient may lose vision, and even end up plainly visually impaired. The sickness for the most part influences the two eyes, albeit one may have more serious signs and indications than the other. There is a little space in the front of the eye called the "foremost chamber". A clear fluid stream all through the foremost chamber, this liquid sustains and washes adjacent tissues. In the event that a patient has glaucoma,the liquid does not deplete legitimately - it empties too gradually - from the eye. This prompts liquid develop, and weight inside the eye rises. Unless this weight is cut down and controlled, the optic nerve and different parts of the eye may end up plainly harmed, prompting loss of vision. There are two principle sorts of glaucoma, open edge and shut point (edge conclusion) glaucoma. The liquid in the eye courses through a range between the iris and cornea, where it escapes by means of the trabecular meshwork - "edge" alludes to this zone. The trabecular meshwork is made of sponky tissue lined by trabeculocytes. Liquid channels into s set of tubes, known as Schlemm's trench, from which they stream into the blood framework

Track 12: Clinical Optometry:

Clinical optometry defines the practice of examining and treating disorders occurs to the eye to improve. Doctors of optometry use special instruments to measure defects in vision and prescribe contact lenses or eyeglasses to correct deficiencies. They may also perform minor surgeries to remove foreign bodies from an eye and suggest exercises to improve the way eyes function. In a clinical optometry examination, doctor measures the patient’s ability to see objects at various distances, along with the ability to see color and light. An optometrist also looks disease that might be linked to declining eyesight. He or she typically measures pressure in the eye to detect glaucoma, a common disorder as people age, where too much pressure occurs in the eye. If left untreated, glaucoma could cause permanent blindness.

Clinical optometry also includes observation for cataracts, a condition marked by clouded lenses. Cataracts might cause vision loss and is also related to aging. If this disorder is discovered, the optometrist commonly refers patients to an ophthalmologist for surgery to remove cataracts. An optometrist also refers patients to medical doctors and specialists for other diseases or injuries that affect vision.

Major Eye Health Issues:

Many eye diseases have no early adverse effects. They might be basic, easy and you may see circumstances in your vision until the disease has become quite extreme. The best way to protect your vision is through usual professional eye check-ups. During check-ups if you think your eye may get injured, immediately contact your eye care professional. Eye disease victim may face various eye conditions such as-

Absence of eye or eyes (anophthalmos), Frequent Blinking (cranial nerve palsy, blepharospasm, Parkinson's disease eye), Bloodshot eye, Blurred vision (myopia/hyperopia), Bump on eye (papilloma, sty, milia), Cloud shape in vision, Crossed eyes, Distorted vision, Discharge, Floater in vision, Iris defect, Lazy eye and many more. The most common causes are –

• Presbyopia – because of hardening of lens of the eye there is difficulty in focusing on objects that are close. This is type of refractive error that focuses light behind rather than on the retina.
•  Cataracts - clouding or darkness of the lens in the eye which leads to a loss of vision. Cataracts often develop slowly and can affect one or both eyes.  Poor vision caused by cataracts may also result in risk of falling and depression.
• Glaucoma - harms the eye’s optic nerve. Main cause is extra fluid pressure build up in the eye. 
• Macular degeneration - also known as AMD (age-related macular degeneration) that causes the graduate loss of sight because of blurring or loss of central vision. Victim face distorted vision (straight line may appear wavy).
• Diabetic eye disease.
• Aging is the main cause of blindness in people.
• Eye infection, inflammation, or injury.
• Night blindness- also called “nyctalopia.” People experience poor vision at night or in dimly lit environments.
• Retinal detachment – the retina separates from the layer underneath. Common symptoms include number of floaters and glances or flashes of light.
• Optic Neuritis -also known as optic papillitis. Symptoms include inflammation of the optic nerve from infection or multiple sclerosis.
• Stroke.
• Brain tumour.

Treatments:

• On the basis of condition and lifestyle, you may be able to choose from corrective lenses, contact lenses, or surgery to improve your vision.
• In case of cataract the surgeon will take out your lens and replace it with a man-made (artificial) one.
• Eye drops lessen the formation of fluid in the eye or increase its outflow. Aftereffects may include allergies, redness, stinging, blurred vision, and irritated eyes. 
• Laser surgery or LASIK is a surgical procedure that uses a laser to correct near-sightedness, farsightedness, and/or astigmatism. In LASIK, a delicate flap in the cornea is set up using either a microkeratome blade or a femtosecond laser. 
• Trabeculectomy the doctor creates a new duct or cannal to pool the fluid and ease eye pressure.
•  Intravenous steroid therapy might speed vision recovery, but it doesn't appear to affect the extent of vision you'll restore. 
• Lucentis works by repressing proteins called vascular endothelial growth factor (VEGF), which encourage the growth of new blood vessels in the body. VEGF may count out to development of macular degeneration by encouraging the growth of abnormal blood vessels in the retina.
• A potential asset of Eylea, also known as VEGF Trap-Eye, is that its recommended dosage is an injection into the eye at an interval of eight weeks.
