Care Philosophy

This content was provided by Dr. Maggiano "I am an expert witness for many types of macular, retinal and optic nerve problems, including malpractice. I work for you, not your insurance company. I investigate loss of vision when no one can figure out what is going on. We have a retinal and macular function laboratory with an outstanding reputation. We accept all reasonable insurance payments. Please phone if question. We are an academically oriented private practice with 5 retinal specialists. My CV is available at WWW.OCRETINA.NET."

Be careful!! I saw Dr. Maggiano for 3 months and he performed 2 detached retina surgeries for me (same eye). I went to UCLA for a 2nd opinion...they found 1). I had detached again in that eye 2). That I could detach at ANY MOMENT in my other eye AND 3). That I had glaucoma in BOTH eyes! How could this be??? How could I see him 1-2 times a week - and he didn't find this...AND never told me!!! They performed retina surgery and put a valve in one eye for the glaucoma! PLEASE be careful!!

I had a retinal tear, saw another doc in this office on Friday AM who said, I'm going to visit my daughter at school this weekend, so I'll do your surgery on Monday. Don't move your head around too much. By the afternoon I was completely blind in that eye. I called back in a panic; Dr. Maggiano set up my surgery for 6AM Saturday morning, re-attached the retina and saved my sight. He's a little gruff sometimes. And he saved my sight.
