简要总结
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.
详细描述
Eyes with loss of vision from retinal or optic nerve conditions generally considered irreversible will be treated with a combination of injections of autologous bone marrow derived stem cells isolated from the bone marrow using standard medical and surgical practices. Retinal conditions may include degenerative, ischemic or physical damage ( examples may include macular degeneration, hereditary retinal dystrophies such as retinitis pigmentosa, stargardt, non-perfusion retinopathies, post retinal detachment. Optic Nerve conditions may include degenerative, ischemic or physical damage ( examples may include optic nerve damage from glaucoma, compression, ischemic optic neuropathy, optic atrophy ). Injections may include retrobulbar, subtenon, intravitreal, intraocular, subretinal and intravenous. Patients will be followed for 12 months with serial comprehensive eye examinations including relevant imaging and diagnostic ophthalmic testing.

入选标准
- •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.
排除标准
- •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.

结局指标
主要结局
Visual Acuity
时间窗: 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.
次要结局
- Visual Fields(Change from pre-procedure to 12 months)
- Optical Coherence Tomography (OCT)(Change from pre-procedure to 12 months)
