Dry Eye Consultation
Dry eye is caused by either a patient not secreting enough water into their tears (often a problem post-menopause or associated with certain inflammatory conditions), or excessive evaporation of the watery component of the tears (often due to blocked oily glands on the lid margin).
Dry Eye signs and symptoms can include:
· Dryness of the eye
· Mucous discharge
· Redness
· Sandy or gritty feeling
· crusty or salty lid margins
· Itching
· Burning
· Constant or occasional tearing
· Watery eyes
· Light sensitivity
· Eye pain or soreness
· Lid infections
· Styes
· Tired eyes
· Contact lens discomfort
About 85% of dry eye patients have a significant underlying evaporative component. The openings of the Meibomian glands on the lid margin get narrower as we get older and the lipids in the glands tend to stagnate and become more viscous. This means that secretions are reduced and can solidify, effectively plugging the openings.
These blocked glands often become inflamed and infected. This is called blepharitis which can make your eyelids red, itchy, burning, sore or sting. In severe cases, your lashes may fall out, the eyelids become swollen and you can develop corneal ulcers and styes. The symptoms can often be worse in the morning and when you wake up you may find your lids are stuck together.
Paradoxically, watery eyes are often caused by the release of reflex tears due to the irritation caused by dry eye damage to the cornea. Reflex tears don’t provide a good, balanced tear film (unlike background tears). Often the eye is less well lubricated after a period of reflex tearing.
When dry or watery eye symptoms are experienced for the first time or increase significantly, we recommend an assessment by our optometrists. At Eyecare Specialists we offer consultations to discuss the management of your dry eye symptoms. This examination involves assessing both the quality and the quantity of the tears as well as investigating the wider health of the ocular surface and eyelids. We can then make personalised recommendations based on your specific symptoms.
At Eyecare Specialists, we also offer in-practice treatments for moderate to severe dry eye - for example Intense Pulsed Light (IPL) and punctal occlusion. IPL treatment reduces inflammation and stimulates the lipid glands by PhotoBioModulation. This enables better secretions whilst also killing mites and bacteria living in the oily glands. Punctal plugs can reduce the speed the tears drain away, usually by occluding the larger lower duct. This can be helpful when a very low tear volume is present. In more severe, aqueous deficient dry eye the upper puncta are often occluded as well. In cases where totally occluding a puncta is too much, a perforated plug can be fitted, which reduces drainage though the puncta, rather than arresting it completely.
