Study for Remote Investigation of Evaporative Dry Eye Disease
(I CRIED)
What this study is about
Dry eye disease is a common problem that can make your eyes feel uncomfortable and affect your vision, making daily tasks harder. Many past studies on dry eye treatments haven't worked well because they didn't include enough people or different types of people.
View original scientific description
Dry eye disease is a common problem that can make your eyes feel uncomfortable and affect your vision, making daily tasks harder. Many past studies on dry eye treatments haven't worked well because they didn't include enough people or different types of people. Doing studies at home instead of at the doctor's office can help more people join and make it easier to find out which treatments really work.
Primary outcome measures
Completion of Surveys and Receipt of Samples
Time frame: 4 weeks
The primary outcome is the rate of successful completion of the OSDI and SPEED surveys at two time points and the receipt of two clinical samples from two time points.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Evaporative loss dry eye disease will be confirmed by screening clinical examination. Patients with evaporative loss dry eye disease will have minimal to no corneal staining and have normal aqueous (water) tear production. Eligible patients with evaporative loss dry eye disease over the age of 18 will be offered study participation.
- There will be no ethnic restrictions on enrollment. All adults (18 years of age or older) with evaporative loss dry eye disease regardless of race or ethnicity will be recruited for participation.
- All adults (18 years of age or older) with evaporative loss dry eye disease , regardless of sex/gender are eligible for recruitment. Women will not be excluded if they are pregnant or breastfeeding.
- All adults age 18 or older with evaporative loss dry eye disease will be recruited for participation. Dry eye disease is not common in the pediatric population and younger children would require assistance with electronic symptom logging and self-performed ocular surface sample collection. Therefore, this study of feasibility of decentralized dry eye disease study will exclude children.
- No treatment is administered in this non-interventional feasibility trial, therefore if pregnant women have dry eye they can participate with no risk to the fetus.
Exclusion criteria
- Patients with keratoconjunctivitis sicca (clinically significant decrease in aqueous production) will not be included. This is because the population with this dry eye disease subtype is at higher risk for corneal epithelial breakdown and ocular surface infection.
- Patients unwilling to measure their own tear production at home will be excluded.
- Patients without internet access or reasonable proximity/access to a post box will be excluded.
- Eyedrop use is not an exclusion criterion.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
