Treatment and Service Offerings
Medical Retina Care
Macular degeneration care: manages dry AMD through monitoring and risk-reduction guidance and wet AMD through anti-VEGF injection therapy when indicated.
Diabetic retinopathy care: manages early and advanced disease through systemic-risk coordination, laser therapy, anti-VEGF injections, and vitrectomy when necessary.
Branch retinal vein occlusion care: treats retinal swelling and abnormal vascular growth through injected medications, focal laser, panretinal photocoagulation, or other individualized treatment.
Central retinal artery occlusion care: provides urgent diagnosis and management for sudden arterial blockage and coordinates care for associated vascular risks.
Floaters and flashes evaluation: provides prompt dilated examination to distinguish benign vitreous changes from retinal tears or detachments.
Retinal Surgery
Retinal-detachment repair: performs vitrectomy, scleral buckling, pneumatic retinopexy, laser treatment, or cryotherapy according to the detachment’s characteristics.
Macular-hole surgery: performs vitrectomy with placement of an intraocular gas bubble to support closure and healing.
Diabetic vitreous surgery: performs vitrectomy for non-clearing vitreous hemorrhage or retinal detachment associated with advanced diabetic retinopathy.
Complex retinal surgery: provides operative care through two dedicated surgical facilities for conditions requiring hospital or ambulatory-surgery-center treatment.
Injections, Laser, and Office Procedures
Intravitreal injections: provides anti-VEGF and other indicated retinal medications for wet AMD, diabetic macular edema, and retinal vascular disease.
Retinal laser photocoagulation: performs treatment for leaking or abnormal retinal vessels, proliferative diabetic retinopathy, and selected vascular conditions.
Laser retinopexy: performs barrier laser around suitable retinal tears to reduce progression to retinal detachment.
Cryopexy: performs freezing treatment around selected retinal tears to create a protective adhesion.
Pneumatic retinopexy: performs gas-bubble treatment for selected retinal detachments, combined with laser or cryotherapy to seal the tear.
Diagnostic Retina Services
Dilated retinal examination: provides vision testing, intraocular-pressure measurement, pupil dilation, and specialist examination of the retina and vitreous.
Optical coherence tomography: provides cross-sectional retinal imaging for macular degeneration, macular holes, diabetic retinopathy, vein occlusion, swelling, and epiretinal membranes.
Fluorescein angiography: provides dye-based imaging of retinal circulation, leakage, vessel damage, and abnormal blood-vessel activity.
Indocyanine green angiography: provides infrared imaging of deeper choroidal blood vessels and structures beneath the retina.
Fundus photography: documents the retina, macula, optic nerve, blood vessels, and vitreous for comparison over time.
Research and Referral Services
