Study of Platelet Rich Plasma Drops to Moderate Clinically Significant Dry Eye

July 14, 2026 updated by: University of Rochester
This is a single center double-masked study with up to four visits. Subjects who have been diagnosed with dry-eye syndrome at Flaum Eye Institute will be enrolled. The purpose of the study is to determine if using platelet rich plasma drops can improve clinically significant dry eye in patients and determine if there is a difference with using two different uses of the plasma tear drops: platelet rich plasma tears and plasma tears without platelets.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: Platelet Poor Plasma Tear
Other: Platelet Poor Plasma Tear Drops
Participant blood will be drawn and processed by the University of Rochester Transfusion Medicine and Blood Bank. Processing will isolate the platelet free fraction of the blood plasma. After processing, plasma should contain ≤ 5% concentration of white blood cells (WBC), red blood cells (RBC), and platelets when compared to the concentration before processing.
Experimental: Platelet Rich Plasma Tears
Other: Platelet Rich Plasma Tear Drops
Participant blood will be drawn and processed by the University of Rochester Transfusion Medicine and Blood Bank. Processing will isolate the platelet fraction of the blood plasma. After processing, plasma should contain ≤ 5% concentration of WBC and RBC and 100 x 10³ μl or ≥ 50% recovery of platelets when compared to the pre-platelet count.

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
Mean change in acuity
Time Frame: baseline to 3 months
Acuity will be measured using a Shack-Hartmann Wavefront Sensor. Subjects will be seated in front of the wavefront sensor. They will be asked to blink naturally fixate on the laser spot throughout the measurement protocol. While subjects fixate, the wavefront sensor delivers a brief flash of light to the subjects' retina. The light reflected out of the subjects' eye is collected to obtain measurements of wavefront aberrations of the eye. For optical quality assessments the measurements of wavefront aberrations will be acquired along the line-of-sight. The wavefront data acquired from the wavefront sensor will be described by Zernike coefficients, the most popular mathematical way to represent the ocular aberrations.
baseline to 3 months
Mean change in breakup pattern to appear
Time Frame: baseline to 3 months
This will be measured using a Placido Disk. The subject places their chin on a chin rest and look into the disk system. The system uses an incandescent or broad-band area LED for illumination.
baseline to 3 months
Mean change in lipid coverage of the cornea with blinking
Time Frame: baseline to 3 months
This will be measured using a Ellipsometer/Tearscope. This instrument uses a modified slit-lamp head restraint and an imaging system to visualize the surface of the subject's cornea. Structurally the system is a clinical slit-lamp system. However, the system uses an electronic camera instead of a human observer. The illumination system uses a diffuse ring illuminator instead of a slit-lamp. The data from this instrument identifies changes in the lipid thickness and the refractive index over the cornea.
baseline to 3 months
Mean change in consistency of lipid compensation
Time Frame: baseline to 3 months

Structurally the system is a clinical slit-lamp system. However, the system uses an electronic camera instead of a human observer. The illumination system uses a diffuse ring illuminator instead of a slit-lamp. The data from this instrument identifies changes in the lipid thickness and the refractive index over the cornea.
baseline to 3 months
Mean change in temperature over the optical service
Time Frame: baseline to 3 months
This will be measured using a Thermal Imaging System. A thermal imaging system will be used to provide spatially-resolved thermal maps of the subject's eyes and face adjacent to the eyes. This camera system is non-invasive and is mounted on a tripod about 12" from the subject's eyes. It images the heat that is emitted by the subject at frame rates from 2 to 10 Hz. The camera displays a spatially resolved map (approximately 0.2 x 0.2 mm pixel size) of the ocular surface temperature. IR detection is a convenient tool for instantaneous temperature measurement of the ocular surface and allows monitoring of time course change as well.
