Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes of Schirmer's test
Time Frame: 8 weeks
Schirmer's test determines whether the eye produces enough tears to keep it moist. Units: mm (in 5minutes)
8 weeks
Changes of tear meniscus height
Time Frame: 8 weeks
Slit lamp Ocular Surface Analyzer is utilized to measure tear meniscus height. Units: mm
8 weeks
Changes of non-invasive tear break-up time (NITBUT)
Time Frame: 8 weeks
Ocular Surface Analyzer is utilized to measure non-invasive tear break-up time. Units: sec
8 weeks
Tear break-up time (TBUT)
Time Frame: 8 weeks
Slit lamp ocular Surface Analyzer is utilized to measure fist tear break-up time with slit lamp. Units: sec
8 weeks
Changes of accommodation
Time Frame: 8 weeks
Speedy-I is utilized to measure the accommodative micro fluctuation test of the ciliary muscle. Units: HFC
8 weeks
Ocular Surface Disease Index (OSDI)
Time Frame: 8 weeks
The Ocular Surface Disease Index (OSDI) is a 12-item scale for the assessment of symptoms related to dry eye disease and their effect on vision. Units: point
8 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes of eye pressure
Time Frame: 8 weeks
Eye pressure is measured in millimeters of mercury (mm Hg).
8 weeks
Changes of Intraocular pressure (IOP)
Time Frame: 8 weeks
Eye pressure is measured in millimeters of mercury (mm Hg). Units: mmHg
8 weeks
Changes of Near point of convergence (NPC)
Time Frame: 8 weeks
RAF rule were initiated in order to normalize NPC. Record as break/recovery. Units: cm
8 weeks
Changes of Stereo vision
Time Frame: 8 weeks
The Randot Stereotest is utilized to evaluate the depth perception. Units: sec
8 weeks
Changes of binocular motor fusion
Time Frame: 8 weeks
The test is utilized to evaluate to assess binocular motor fusion, specifically the extent to which a patient can maintain binocular single vision (BSV) in the presence of increasing vergence demands. Units: prism
8 weeks
Changes of Amplitude of accommodation (AA)
Time Frame: 8 weeks
The amplitude of accommodation is the maximum potential increase in optical power that an eye can achieve in adjusting its focus. It refers to a certain range of object distances for which the retinal image is as sharply focused as possible. Units: diopter
8 weeks
Changes of Amplitude of Flipper facility
Time Frame: 8 weeks
Vergence facility (VF) was measured by using a prism flipper to evaluate the ability of the fusional vergence at near with +/-2.00 flipper. Units: cpm
8 weeks
Changes of Fundus photography
Time Frame: 8 weeks
The fundus is the back of the eye and includes the retina, optic nerve, and retinal blood vessels.
