简要总结
The aim of this study is to develop a less risky, yet effective and more sustainable treatment for retinal vein occlusions than the current commonly used approach of repeated intravitreal triamcinolone acetonide (Kenalog) injections. The types of retinal vien occlusion that are being studied include central (CVRO), hemi-retinal (HRVO),and branch (BRVO) retinal vein occlusion. Niacin, (Nicotinic Acid, not Nicotinamide) a B-vitamin, has lipid lowering and vasodilating properties. The combination of Niacin and Prednisolone Acetate steroid eye drops as a non-invasive treatment approach was developed by the Principal Investigator. The Niacin dilates the retinal vessels, hopefully encouraging earlier collateral vessel formation aimed at bypassing the venous obstruction, thus restoring venous outflow. The Prednisolone Acetate steroid eye drops are aimed at reducing vascular leakage and therefore the macular edema in the eye while the Niacin is taking effect.
详细描述
A spontaneous improvement was noted in some patients who were experiencing deteriorating retinal vein occlusions. A chart review and questioning of the patients revealed that the addition of Niacin by the Internist seemed to be the factor that was bringing about the vision improvement.
The Niacin has vasodilating properties, and it is postulated that as the Niacin dilates the retinal vessels, it will encourage earlier collateral vessel formation that will bypass the venous obstruction, and restore venous outflow. The prednisolone steroid eye drops will hopefully reduce the macular edema in the eye.
This is a retrospective study conducted by chart review of up to 45 patients who have undergone treatment with 1500 mg per day of oral Niacin (Nicotinic acid) with or without topical steroid eye drops, Prednisolone acetate (Pred Forte) for the treatment of retinal vein occlusion central (CRVO), hemi-retinal (HRVO), branch (BRVO). The retrospective chart review of patients seen by Dr. Michael Gaynon will go back to 1998 and will continue through the present time. All patients with vision impairment caused by deteriorating retinal vein occlusion, and who were or will be prescribed the Niacin with or without Pred Forte treatment will be included.
