Dr. Campbell is among the first vitreo-retinal specialists in South Texas to incorporate the OCT to practice. This minute long procedure is critical in early detection and treatment of retinal conditions such as macula edema, choroidal neovascular membrane, macular holes, and optic nerve atrophy. The OCT is an imagery technology which allows Dr. Campbell to study a cross sectional image of the retina. Dr. Campbell will often follow individual retinal conditions with a series of OCT’s. The comparision value is “invaluable” says Dr. Campbell.
