It can occur at any age but people over 40 are at a higher risk.
Men are more prone to it than women.
People who are extremely nearsighted.
People with a family history of retinal detachment.
People with other eye diseases or injuries.
What is computer vision syndrome?
A number of professionals using computers experience vision and eye-related problems especially due to poorly designed work stations and prolonged usage. These vision-related problems are grouped as Computer Vision syndrome in short "CVS".
What are its symptoms?
The primary symptoms are :
Eye strain
Blurred vision
Dry and irritated tired eyes
Headaches
Neck and backaches
Who is affected? How?
Computer Vision Syndrome ( CVS ) affects 75% of computer users, most markedly those who work more than 3 to 4 hours with computers. Computer users' productivity is affected.
What are the reasons?
Uncorrected refractive error
Decreased blink rate
Glare and reflection from the monitor
Poor Ergonomics
What does a computer vision clinic do?
Evaluate at simulated computer environment ( Questionnaire + Executive Vision check + Orthoptics + Tear function )
Management
Glass
Artificial tears
Vision therapy
Recommendations about ergonomics
What are the symptoms of cataract?
Cloudy or blurry vision.
Problems with light, such as headlights that seem too bright, glare from lamps, or very bright sunlight.
Colors that seem faded.
Poor night vision.
Frequent changes in glasses or contact lenses.
What is Cataract?
Cataract is the clouding of the eye's lens leading to blurred vision and blindness.
Who gets cataract?
People over 60 years, Infants with congenital cataracts due to mother having infectious diseases during pregnancy.
How is cataract treated?
Cataracts are removed through surgery which lasts about 10-20 minutes. The natural lens is removed under local anaesthesia and replaced with an intraocular lens.
How effective is the surgery?
The surgery has an over 98% success record resulting in better vision.
What is the cost of cataract surgery?
The cost depends upon the lens used. It varies between Rs. 20,000/- and Rs. 50,000/- per eye.
What is glaucoma?
The fluid within the eye called the aqueous humor usually exerts a pressure between 12 to 18 millimetres of mercury. The abnormal rise of this pressure is called Glaucoma. This pressure damages the nerve fibres and causes irreparable damage resulting in gradual loss of vision leading to blindness. Can Glaucoma be cured? No. It can only be controlled. The lost vision can not be regained.
Who gets Glaucoma?
Over 40 years of age
Have a family history of glaucoma
Diabetic
Abnormally high IOP
Nearsighted
Regular, long-term use of steroids/cortisone
Previous Eye injury
How can IOP be measured?
IOP can be measured using a tonometer which could be used in the diagnosis and treatment of glaucoma. Causes of high IOP: The clogging of the paths and chambers in the eye which traps the aqueous humor results in a pressure buildup leading to high IOP.
How is glaucoma treated?
Glaucoma is a chronic disease and requires constant medication to lower the IOP levels. Surgical procedures are used if the medication is unsuccessful.
What is corneal grafting?
When the cornea is damaged beyond repair it is removed either fully or partly and replaced by a donated cornea.
What is the cornea?
The cornea is the clear outer layer covering the eye. It helps focus and transmit light as it passes through the lens onto to retina.
Who will require corneal graft?
People with congenital abnormalities that inhibit normal vision.
People with clouded corneas through childhood diseases, trauma, or infections.
People with degenerative eye diseases that cause loss of vision.
Who can donate corneas?
Anyone with no infectious diseases.
What should we do after the surgery?
Avoid rubbing the eye. Use only the prescribed medicines and eye drops. Report to the doctor immediately if there is sudden pain, redness, decrease in vision, or excessive discharge.
What is diabetic retinopathy?
Diabetic retinopathy is the damage caused to the retina (the inner layer of the eye) due to diabetes. It is a leading cause of blindness in adults.
How is it treated?
It is treated with laser photocoagulation and vitreoretinal surgery.
What is a squint?
A squint, also called strabismus, is a condition in which the eyes do not line up in the same direction. As a result, both eyes are not looking at the same object at the same time.
What causes squint?
Refractive errors
Muscle imbalance
Long-sightedness (hyperopia)
Neurological problems
How is squint treated?
Squint can be treated with glasses, patching of the stronger eye, surgery, or a combination of all three.
