Eye Concerns


Teary Eyes All the Time

My Eyes water/tear all the time??
Many of our patients present with a complaint of “teary/watery” eyes. A thorough eye examination is necessary for the evaluation of underlying causes. Anatomically, tears in our eyes are produced by 3 glands:
⦁    Lacrimal Gland – produce aqueous (watery) tears
⦁    Meibomian Glands – produce oily tears
⦁    Goblet cells – produce mucous tears

Tears drain the eyes through a channel called the lacrimal punctum into the lacrimal sac and further into the nasolacrimal duct. One can experience teary/watery eyes due to 4 main causes:
⦁    Blocked punctum – If the Punctum is blocked or has stenosis (narrowing), there will be decrease in drainage of tears, which would cause the tears to overflow
⦁    Dry Eye Syndrome – Inconsistent/insufficient oil layer on the front surface of the eye can cause eyes to excessively water/tear. Lack of oil layer causes dryness of the front surface of the eye, which overstimulates lacrimal gland’s production of watery tears.
⦁    Consistent irritation with an allergen – Work/home environment can have pollutants/irritants (example – dust, mold etc) that irritate the front surface of the eye causing it to tear.
⦁    Eyelid abnormality – Ectropion (eyelid turned out), entropion (eyelid turned in) and irritation to the front surface of the eye by eyelashes can cause the eyes to tear excessively.

Infants can sometimes experience teary eye. This symptom is most commonly due to obstruction at the end of nasolacrimal duct (valve of Hesner). As the tears stay stagnant in the nasolacrimal duct, potential for infections also remains. Most cases resolve with hydrostatic/lacrimal massage but some require minor surgical interventions.

It is strongly advised to get any of the eye symptoms evaluated by your eye care physician. Symptoms can overlap and hence it is important to diagnose the underlying cause.

Digital Screens and Vision

Effect on digital screens on our vision. Part 1
Latest research suggests more people are becoming shortsighted (myopia) now than they were a decade ago1. This comes as no surprise as it has been proved over and over again that excessive near work can promote myopia progression.
The direct link of digital screens and myopia progression has not been made yet, however, the progression is happening too quickly for it to be purely genetic or environmental 1. Most parents ask a consistent question about their child’s prescription increasing too quickly, and we believe there is a direct link to digital screen time (computers, laptops, tablets, smartphones, etc).
Other than myopia progression, we have also noted unstable tear film, Meibomian gland dysfunction and other eye surface conditions causing Dry Eye Syndrome at a very young age. The important thing to note is that children will not complaint of dry, irritated, red eyes or report of blur in most cases. Hence it is very important for the parents/guardians to be vigilant and get comprehensive eye examinations every year for the children.
