![]() These tears tend to be milky and may cause smoky vision after instillation. Lipid based emulsions are used to combat dysfunctions of the oil layer, often caused by meibomian gland dysfunction and blepharitis. Our favorite lubricants currently include Oasis Tears and Oasis Tears Plus (PF), Retaine MGD (PF), Theratears Xtra (P), Refresh Repair (TP), Refresh Mega-3 (PF), Celluvisc (PF) and Tears Again Liposome Spray. To combat these tear film dysfunctions, researchers have developed multiple artificial tear types aimed at the varying components of the tear. Dysfunction in any of these layers can begin the inflammatory cycle that is dry eye. Finally, the outer oil layer is comprised of lipids that slows evaporation. The middle aqueous layer provides moisture and antimicrobial enzymes. The inner mucosal layer helps the tear stick to the eye. Your tears are made of three main components, the inner mucous layer, the middle aqueous layer and the outer oil layer. Artificial tear technology has progressed dramatically in the last decade, seeing the introduction of several new types of tear replacements that aim to target specific tear components. Regardless, their correlation between low amounts of wetting and dry eye remains high.Īrtificial tears and lubricants have been the mainstay in dry eye treatment since the beginning. There does exist some controversy regarding both tests as to what they actually measure, be it tear volume, basal tear secretion, reflex tearing or a combination of the three. By placing one of these threads or strips in the eye it is possible to assess certain aspects of your dry eye. Phenol red threads and Schirmer’s strips are used to determine tear quantity. Lissamine Green stains dead cells due to desiccation and highlights conjunctival damage. Sodium Fluorescein (yellow) allows the doctors at the Visionary Eye Center to evaluate how quickly your tear film breaks apart and stains damaged areas of the eye, especially on the corneal surface. We know that factors like age, being female, prior refractive surgery like LASIK, certain medications like Accutane, conditions like Sjogren’s disease, excessive multivitamin use, radiation treatments and diets low in vitamin A and omega-3 fatty acids increase the risk that you will experience dry eye syndrome.ĭuring a dry eye care appointment at our Reno clinic, diagnostic dyes are used to assess tear film quality and surface damage. As many as 3.2 million women and 1.68 million men over 50 in America are affected by dry eye syndrome.
