Eligibility |
Inclusion Criteria: 1. Is at least 21 years of age and has full legal capacity to volunteer; 2. Has read and signed the information consent letter; 3. Is willing and able to follow instructions and maintain the appointment schedule; 4. Is diagnosed with dry eye syndrome (in at least one eye), indicated by current ocular examination, prior history (self-reported history of dry eye is acceptable) and current use of treatments for dry eye; 5. Has a minimum osmolarity reading of 316 mosm/kg at the baseline visit in at least one eye or a osmolarity reading of at least 308 (in worse eye) and at least an 8 point difference between the two eyes. Exclusion Criteria: 1. Has taken part in another research study within the last 30 days; 2. Planned contact lens wear during the course of the study; 3. Staff at the investigational site or family member of site staff or family member of currently enrolled participant; 4. Any subject that violates the washout period by using eye drops during the 72hrs washout period; 5. Has any known ocular disease* including active ocular infection, inflammation or allergy, especially Salzmann's nodular degeneration, symptomatic conjunctivochalasis, and fixation disparity syndrome; 6. Restasis use can be included if they have been on it for at least 3 months and are stable.Used Restasis (or similar topical medication) within the last 6 months; 7. Has a systemic condition that in the opinion of the investigator may affect the dry eye status of the subject, especially those newly diagnosed, newly prescribed and/or unstable; 8. Is pregnant, lactating or planning a pregnancy at the time of enrolment (verbal confirmation necessary); 9. Use of systemic anti-histamines, as long as they have been on them continuously for at least 1 month. Use of medications such as: Systemic Antihistamine (e.g., Allegra®, Benadryl®, Claritin®, Dimetapp®, Unisom®, Zyrtec®, etc.), Isotretinoin (e.g., Accutane®, Roaccutane®, Amnesteem®, Claravis®, Isotroin®, Sotret®) or similar medications; 10. Has known sensitivity to the diagnostic pharmaceuticals to be used in the study; 11. Has undergone ocular surgery(LASIK, Cataract, etc)within the last year; - For purposes of this study, ocular conditions that are typically associated with dry eye status, such as meibomian gland dysfunction, mild (i.e. not considered clinically relevant) blepharitis, corneal and conjunctival staining are not considered an exclusion. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in Tear Osmolarity | Osmolarity measures will be evaluated using the eye with the highest osmolarity reading at the washout/baseline visit. These baseline values will be compared to subsequent follow-up visits, to determine change from baseline at each visit as well as cumulative change in osmolarity over time. | 8 weeks | |
Secondary | Change in Visual Acuity | Visual acuity measures will be evaluated using the eye with the highest osmolarity reading at the washout/baseline visit. These baseline values will be compared to subsequent follow-up visits, to determine change from baseline at each visit as well as cumulative change in visual acuity over time. | 8 weeks | |
Secondary | Change in Tear Film Breakup Time | After instillation of fluorescein, the investigator will ask the participant blink three times and keep their eyes open for as long as they can while the investigator records the time at which the dark spots on the tear film begin to appear. | 8 Weeks | |
Secondary | Change in Corneal Staining | A fluorescein strip will be wetted with a few drops of saline, and applied to the inferior palpebral conjunctiva of both eyes. The eye will be illuminated by cobalt blue light, and viewed through a Wratten no. 12 barrier filter. Fluorescein staining will be assessed using the CCLRU8 scale (0 to 4). | 8 weeks | |
Secondary | Change in Conjunctiva Staining | A lissamine green strip will be wetted and applied to the inferior palpebral conjunctiva of both eyes to assess conjunctival staining. Lissamine conjunctival staining will be assessed using the Oxford scale. If lissamine strip is not available, fluorescein maybe used instead to assess all conjunctival staining. | 8 Weeks |
