Diagnostic Tests to Evaluate Ocular Surface

As with other diseases, early detection and treatment of this disease is more likely to achieve better patient outcomes. Dr. Jackson checks for the signs and symptoms of Ocular Surface/Dry Eye disease using several quick and painless tests to measure visual clarity, tear production, ocular surface dryness and damage to the cornea or conjunctiva, and these tests will help determine the severity of the dry eye and determine the appropriate treatment option customized for you. Below are the tests typically performed by Dr. Jackson and our dry eye specialists:

  • Tear Secretion:Schirmer strips typically used in clinical dry eye studies only
  • Corneal/Conjunctival Stains: vital dyes (fluorescein/lissamine) assess surface damage to the eye, are safe , have been used for years
  • Tear Breakup Time (TBUT): assesses evaporation effect of the oil layer
  • Tear Osmolarity: measures the dehydration status of the eye and is used to measure the response to therapy over time; more accurate than blood sugar tests used by diabetics on a daily basis
  • InflammaDry: quantitative inflammation marker of the ocular surface
  • Lipiview: quantifies the oil layer of the tear film, partial blinking, and meibomian gland structure and atrophy
  • Doctor’s Allergy: in-office allergy skin scratch test applied to both sides of inner arms skin; must stop all antihistamine treatment for 5 days before testing and it quantitates the 60 most common allergens in the Midwest region of the US
  • Patient questionnaires (SPEED, OSDI): real life assessment on how ocular surface disease affects activities of daily life
  • Sjo Finger Stick or Blood Draw: detects early immune titers to help diagnose Sjogren’s Syndrome

Sjogren’s Syndrome is an autoimmune disease that affects approximately 1 in 10 dry eye patients. There are about 3-4 million undiagnosed dry eye patients with Sjogren’s Syndrome. Early symptoms are classified by dry eye and dry mouth, the latter typically with frequent cavities and oral hygiene issues. The morbidity is high if Sjogren’s is not detected early because late disease is characterized by interstitial lund and/or kidney disease and up to 5% of patients developing lymphomas. Sjo blood test detects early antibody titers versus the traditional antibody titers used in the past that are only positive late stage disease and make it very difficult to treat at that point. Dr. Jackson has partnered with several Rheumatologists who specialize in Sjogrens treatment.
