Induction of posterior vitreous separation using LASIK suction ring may have a potential role in the management of diabetic macular edema.
A significant percentage of patients with diabetic macular edema respond poorly to conventional laser photocoagulation. One associated factor in such patients with refractory diabetic macular edema is the absence of posterior vitreous detachment (PVD). Several invasive methods, such as surgical induction of PVD result in resolution of macular edema and improvement in visual acuity. Being invasive such modalities may have important surgical risks, such as retinal detachment and endophthalmitis. Recently, laser in situ keratomeilusis (LASIK), a well-accepted refractive procedure, has been reported to produce posterior vitreous detachment in patients with myopia. We herein hypothesize that application of LASIK suction ring, an external procedure, may be useful in the induction of PVD in patients with refractory diabetic macular edema and may have a better safety profile.
