Project title: One-year Results of the Effect of Intravitreal Bevacizumab (Avastin) on Intraocular Pressure (IOP) in Patients with Neovascular Glaucoma
Human subjects IRB approved project number (where applicable): 092007-009
Animal subjects IRB approved project number (where applicable): N/A
Project Type (patient-based research, animal-based research, or basic research; this characterization is only to permit a general classification for grouping similar types of projects): Patient- based research
Brief Description of Project:
Bevacizumab is one of the first commercially available angiogenesis inhibitors
targeted against vascular endothelial growth factor (VEGF). Recently, its uses
have been broadened to include treatment of neovascular glaucoma (NVG). NVG
is an advanced manifestation of several eye diseases in which there is ischemia
of the retina causing abnormal and progressive blood vessel growth into the
anterior segment. The focus of this project is to determine the effect of Avastin
on intraocular pressure in patients with neovascular glaucoma and to determine
if the anterior chamber angle status (open or closed) is predictive of immediate
and long term IOP response. We anticipate the results will provide valuable
guidance in future clinical decisions regarding timing and optimal use of this
revolutionary treatment modality.
Based upon preliminary data we presented at Texas Ophthalmology Association and earned Best Poster Award for at the American Academy of Ophthalmology, we wish to carry this project to publication.
Under my direct guidance, the medical student will follow me in Glaucoma Clinic on a daily basis, interview and examine patients I select, collect designed information, obtain digitalized images of the anterior chamber angles and assist me in analyzing resultant clinical data. If the student demonstrates initiative, he will be encouraged to participate in presentation at the UTSW John Lynn Lectureship.
