The vitreous causes most diseases of the retina. Retinal tears, retinal detachments, macular holes, epiretinal membranes, macular edema, vitreomacular traction, diabetic retinopathy, diabetic macular edema and diabetic retinal detachments are all related to the vitreous. We suspect even wet macular degeneration may play a role as well, but there is no conclusive evidence. Even floaters, … [Read more...]
Part 2: Stem Cells to be Safe, Too
February 8, 2012 By 6 Comments
Last week we celebrated the announcement of improved vision in the first two patients receiving stem cells transplantation. Truly exciting and encouraging news, but also due to the fact that the methods used seem safe, too. New medical discoveries, treatments, drugs, devices, etc. must all be shown (proven) to be both safe and effective for the patients. Last week, the "results" of these … [Read more...]
Stem Cells Reported to Improve Vision
January 31, 2012 By 25 Comments
Two patients receiving embryonic stem cells for their blinding retinal diseases reported improvement in their vision. The results were released just last week online in the medical journal Lancet. Each patient received retinal epithelial pigment cells (aka RPE cells) grown from human embryonic stem cells. RPE cells are the faulty cells in macular diseases such as ARMD and Stargardt's Disease. … [Read more...]
Retinal Detachment Surgery
January 19, 2012 By 6 Comments
This is my latest recording of surgery for a retinal detachment. This is the second of (what I hope) to be a series of "videos" on the surgical aspects of retinal eye disease. This is a recording of two procedures often combined to repair, or fix, a retinal detachment. Anesthesia Now, this video is quite graphic. Believe it or not, however, the patient is completely … [Read more...]

Silicone Oil for Retinal Detachments
December 20, 2011 By 23 Comments
Silicone oil is used for recurrent retinal detachments or complicated retinal detachments including PVR (proliferative vitreoretinopathy). It can be a valuable tool to prevent blindness. Most retinal detachments are caused by a retinal tear, or hole, in the retina. In either case, this allows for communication between the vitreous cavity and the potential space underneath the retina. … [Read more...]
Retinal Tears and Vitreous Hemorrhage
December 14, 2011 By 11 Comments
A vitreous hemorrhage may be caused by a retinal tear. Sometimes there is so much blood in the eye that direct examination is impossible and we can only guess at the most likely cause. It is the most difficult situation for me to handle as a doctor. Patients lose significant vision as the blood in the middle of the eye physically blocks all light from hitting the retina. While this is … [Read more...]
Eylea As Good As Lucentis
December 6, 2011 By 13 Comments
Last month, the FDA approved Eylea (VEGF-Trap, aflibercept) for the treatment of wet macular degeneration. The new drug does not need to be injected as often as Lucentis, yet it seems that the visual improvement is the same; that is, fewer injections yield similar improvement in vision...for the first year of therapy. Keep in mind that we are always interested in a drug's ability to improve … [Read more...]
