Dry Eyes

ROLE OF TEARS

INCREASED EYE PRESSURE:
Elevated intraocular pressure (I0P) is a primary risk factor for glaucoma. When the fluid inside the eye fails to drain properly, pressure builds up, damaging the optic nerve over time.


AGE:
Advancing age is a significant risk factor for glaucoma. Individuals over the age of 60 are at a higher risk of developing the condition, with the risk increasing with each decade of life.


FAMILY HISTORY:
Genetics play a crucial role in glaucoma. If you have a family history of the condition, you may be at a higher risk of developing it yourself.


ETHNICITY:
Certain ethnic groups, such as African Americans and Hispanics, have a higher predisposition to glaucoma and are more likely to experience severe vision loss from the disease.

EYE AND YOU

OFFICE GOERS

Indoor humidity is increased due to air conditioning ceiling fans and forced air heating leading to rapid tear evaporation, which contributes to dry eye problems

CHILDREN

Medicines like anti-allergic can decrease tear production leading to dry eyes

WOMEN (POST-MENOPAUSE)

The natural ageing process is associated with dry eyes, especially women undergoing menopause

ELDERLY

Certain medicines, including anti-allergics, antidepressants, medications for anxiety, Parkinson’s disease, and high blood pressure have been associated with dry eye.

POST-SURGERY DRY EYES

Eye surgery sometimes leads to less production of tears

COMPUTER VISION SYNDROME

Computer vision syndrome is a complex eye problem related to the eye stress experienced in relation, or during, the use of computer. 

Simple ways to prevent and manage computer vision syndrome

  • Adjust your computer display settings
  • Minimize screen glare. Consider computer eye wear
  • Follow the 20-20-20 rule. After every 20 minutes look at 20 feet away for 20 seconds
  • Consult eye specialist if there is grittiness, burning or foreign body sensation in eyes
  • Use artificial tears as prescribed by the doctor
Are small screens causing bigger vision problems?

Some common symptoms of eye strain are blurry vision, sensitivity to light, headaches, and watery, itchy or burning eyes. These group of symptoms is known as Computer Vision Syndrome. It happens to be a contributing factor for dry eyes.

SYMPTOMS OF DRY EYES

PREVENTION OF DRY EYES

MEDICATION
After complete eye examination, ophthalmologists will prescribe the suitable medication.

SURGERY
Laser surgery such as trabeculoplasty or iridotomy is done to reduce the fluid blockage and eye pressure using lasers. .

Conventional surgery such as microsurgery is done to drain the fluid and ease pressure by creating a new channel near the drainage canal.

DRY EYE TEST

Why is Schirmer’s test done?
Schirmer’s test is done to detect production of tears. An abnormal result will signify dry eyes.

How is Schirmer’s test done?
Schirmer’s test is done in an eye clinic/hospital.

 Step 1
To be seated in a comfortable upright position.

 Step 2
The Schirmer’s test strip will be placed in the lower eye lid.

 Step 3
After 5 minutes the Schirmer’s strip will be removed from the eye. After removing the schirmer’s strip from the eye, the reading is recorded

WHAT IS DRY EYE?

Dry eye is a condition in which a person does not have enough quality/quantity of tears to lubricate and nourish the eye.

HOW DO DOCTORS DIAGNOSE DRY EYES?

A complete eye examination includes:

  • An initial eye examination to determine the overall health of the eyes and reach a diagnosis with presenting symptoms.
  • Schirmer’s test will measure tear production.
  • In certain cases, special tests may be recommended to determine the surface condition of the eyes, which include, use of special dyes in eye drops to determine the surface condition of the eyes.

HOW TO MANAGE DRY EYES?

  1. Blink regularly when using a computer, watching TV and/or using a smartphone.
  2. Frequent breaks from screen can relax the accommodative system of the eyes and prevent ocular strain and visual fatigue. 
  3. Follow the 20-20-20 rule. After every 20 minutes look at 20 feet away for 20 seconds. 
  4.  Consider wearing sunglasses for protection from wind and hot air.
  5. Contact lens wearers should use artificial tears recommended by their doctor to keep their eyes lubricated.
  6. Use artificial tears or tear substitutes, which can help lubricate dry eyes. 
  7. Consume nutrition rich food such as nuts, flax seed, green leafy vegetable, fish etc. and prevent ocular strain and visual fatigue.

WHAT CAUSES DRY EYES?

 There are many factors that can cause dry eyes, it includes the following:-

Age : With advancing age, tear production reduces and there is a gradual loss of tears.

Gender : Women are more likely to develop dry eyes due to hormonal changes such as pregnancy, the use of oral contraceptives and conditions like menopause 

Medication: Certain medicines, including anti-allergic, antidepressants, medications for anxiety, Parkinson’s disease and high blood pressure have been associated with dry eye

What makes it worse?

  • Prolonged reading or digital device use
  • Overexposure to dry environment such as air-conditioned rooms
  • Prolonged contact lens wear
  • Lack of certain nutrients in the diet such as essential fatty acids
  • Certain health conditions such as diabetes, thyroid-associated diseases, rheumatoid arthritis, etc.
