Vitreoretinal Surgery

An evidence-based approach to new retina surgery techniques.

We utilize state-of-the art surgical techniques and diagnostics, many of which we developed in our laboratory. We have a special interest in retina surgeries for hard to fix conditions like retinal detachment, epiretinal membranes, macular holes, optic pits, diabetic retinopathy, uveitis, proliferative vitreoretinopathy, and macular degeneration.

We routinely publish our advanced surgical methods and findings in peer-reviewed journals. Using a unique surgical database, we are able to rapidly identify the cause of surgical complications and modify techniques to fix and avoid them. This rigorous, evidence-based approach to surgery has enormous benefits to our patients.

In the laboratory, we have developed and tested novel wound construction for vitreoretinal surgery in infants and adults. We have also identified key molecules and gene variations that contribute to vitreoretinal disease.

We received grant support from the Fight for Sight organization to study an inherited form of inherited retinal detachment. In this family, children develop severe retinal detachments. Our genetic analysis suggests that a novel gene variant may be the cause, and efforts to identify the variant are...

ADNIV is an inherited autoimmune disease of the eye. We performed a study to determine the benefit of Retisert, an implant that delivers steroids within the eye for several years. In a study published in the journal, Archives of Ophthalmology, we found that the implant inhibited specific features...

Endophthalmitis is a sight-threatening intraocular inflammatory disorder resulting from infection of the vitreous cavity. Following introduction of pars plana vitrectomy (PPV), the role of this treatment modality for endophthalmitis was controversial. Our laboratory is studying whether new surgical...

Whether vitrectomy surgery for age-related macular degeneration (AMD) is harmful or helpful is not known. A study we co-authored suggests there may be some benefit for certain types of AMD. In our study 2009, published in Ophthalmology, we did not detect that vitrectomy surgery increased the...

The vitreous gel normally displays a graded density at different anatomical locations. Although it is estimated to be nearly 90% water, the vitreous gel contains diverse proteins, proteoglycans, and small molecules that originate from within and outside the eye. In specific vitreoretinal diseases,...
