View original scientific description
This study will evaluate the use of autologous bone marrow derived stem cells (BMSC) for the treatment of retinal and optic nerve damage or disease.
Interventions
PROCEDURE
Arm 1
Procedure/ Surgery: RB (Retrobulbar) Retrobulbar injection of Bone Marrow Derived Stem Cells (BMSC) Procedure/Surgery: ST (Subtenon) Subtenon injection of Bone Marrow Derived Stem Cells (BMSC) Procedure/Surgery: IV (Intravenous) Intravenous injection of Bone Marrow Derived Stem Cells (BMSC)
Primary outcome measures
Visual Acuity
Time frame: Change from pre-procedure to 12 months
Best corrected visual acuity will be measured with Snellen Eye Chart and the ETDRS (Early Treatment Diabetic Retinopathy Study)Eye Chart when available at each post- procedure visit. Intervals at minimum will be first post- procedure day,then 3 months, 6 months and 12 months post-procedure day. Recommended visit 1 month post -procedure day.
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
- Have objective, documented damage to the retina or optic nerve unlikely to improve OR
- Have objective, documented damage to the retina or optic nerve that is progressive AND have less than or equal to 20/30 best corrected central visual acuity in one or both eyes AND/OR an abnormal visual field in one or both eyes.
- Be at least 3 months post-surgical treatment intended to treat any ophthalmologic disease and stable.
- If under current medical therapy ( pharmacologic treatment) for a retinal or optic nerve disease be considered stable on that treatment and unlikely to have visual function improvement ( for example, glaucoma with intraocular pressure stable on topical medications but visual field damage ).
- Have the potential for improvement with BMSC treatment and be at minimal risk of any potential harm from the procedure.
- Be over the age of 18
- Be medically stable and able to be medically cleared by their primary care physician or a licensed primary care practitioner for the procedure.
- Medical clearance means that in the estimation of the primary care practitioner, the patient can reasonably be expected to undergo the procedure without significant medical risk to health.
Exclusion criteria
- Patients who are not capable of an adequate ophthalmologic examination or evaluation to document the pathology.
- Patients who are not capable or not willing to undergo follow up eye exams with the principle investigator or their ophthalmologist or optometrist as outlined in the protocol.
- Patients who are not capable of providing informed consent.
- Patients who may be at significant risk to general health or to the eyes and visual function should they undergo the procedure.

- Westport, Connecticut

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.
