Dry Eye FAQ's

What is Dry Eye?
- In medical terms,
  Dry Eye is lovingly known as "KERATOCONJUNCTIVITIS SICCA".
  The tear film consists of 3 layers: A superficial lipid (oily) layer which decreases evaporation, a middle aqueous layer which contributes 90% of the tear film, and a deep mucin layer which facilitates spreading of the tears over the cornea.

How do you treat Dry Eye?
- (1) Stimulation of tear production. Tear production is best stimulated by the topical administration of drops or ointments to the eye to the eyes. Usually 4-6 weeks (sometimes longer) is required for tear production to improve. Usually treatment must be continued for life to maintain tear production, but it is possible in some cases to reduce usage. This is true if KCS is detected early before severe drying is present.
  
  (2) Control of ocular inflammation and infection through the topical application of an antibiotic-steroid preparation. Occasionally antibiotics may be given orally

Can Watery Eyes Be a Symptom of Dry Eye?
- Yes. As odd as it sounds, many Dry Eye sufferers experience â€˜wet eyesâ€™ due to the tear glands overproducing watery or reflex tears to compensate for a lack of a balanced tear film.

Can reading & TV or computer viewing cause Dry Eye?
- During reading and TV or computer viewing, the rate of eyelids blinking reduces significantly. This causes the tear film to evaporate leading to dryness of the eyes. This may happen in some people, more when they are tired, or have spent long hours watching TV or computers. Computer Users tend to blink much less frequently (about 7 times per minute vs. a normal rate of around 22 times/minute).
  
  This leads to increased evaporation along with the fatigue and eye strain associated with staring at a computer monitor. Ideally, computer users should take short breaks about every 20 minutes to reduce this factor. Also, adjusting the monitor so that it is below eye level will allow the upper lid to be positioned lower and cover more of the eyeâ€™s surface, again to reduce evaporation..

What are the warning signs and how is it detected?
- People with Dry Eye have sandy-gritty irritation or burning in their eyes. Initially people may have symptoms only after particularly long days, or when driving, or with contact lens wear, or when exposed to extremely dry environments such as that seen in airplane cabins.
  
  Eventually symptoms become more consistent, and if someone has sandy-gritty irritation or burning that gets worse as the day goes on, and if they have had these symptoms for more than a few days, Dry Eye should be ruled out by an eye doctor.
  
  We will review your history and examine your eyes to make sure you do not have any other problems, and determine the cause for your Dry Eyes.

Can Dry Eye syndrome come and go?
- Dry Eye syndrome does not truly come and go, but in the early stages of the condition, or with mild Dry Eye, you may only have symptoms after long days, or with environmental conditions that decrease your blink rate (i.e. computer use) or under conditions that increase evaporation from your tear film (i.e. wind, dry air, etc.).
  
  Some patients may notice discomfort only when they wear their contact lenses. Some people may develop symptoms only when they are dehydrated--just like your mouth becomes dry, your eyes can become dry in this way.

What if I don't treat Dry Eye. Can I lose sight?
- If untreated, Dry Eye can progress to a more irritable, troublesome condition called chronic conjunctivitis. It can cause considerable trouble, and Dry Eye can lead to loss of sight due to corneal scarring, so delaying treatment is not recommended.

Is there treatment for corneal scarring caused by Dry Eye
- When patients experience corneal scarring from Dry Eye, sight may be restored by corneal transplants. However, the original cause of the scarring should be addressed to prevent a recurrence of vision loss.

What can I do to prevent or control Dry Eye syndrome?
- Have annual eye exams.
