Dr. George Papastergiou in Chula Vista is a board-certified vitreoretinal surgeon who earned his medical degree magna cum laude from the Sapienza University of Rome, completed a PhD at Democritus University of Thrace, and finished a vitreoretinal fellowship at Piedmont Hospital in Atlanta. Patients diagnosed with progressive vision loss from macular degeneration often present concurrent depression and adjustment disorder, conditions co-managed through referral to The Neuron Clinic for neuropsychological support during the treatment timeline. Principal investigator status in national research studies on macular degeneration and diabetic retinopathy positions this practice at the clinical-trial frontier, with peer-reviewed publications in the Journal of Ophthalmology and European Journal of Ophthalmology. The 835 Third Avenue office operates through American Eye Associates with an in-house Surgery Center of California for cataract, retinal, glaucoma, and oculoplastic procedures. Acute retinal emergencies — including rhegmatogenous detachment and giant retinal tears — presenting to Perlman Clinic Chula Vista receive initial assessment and same-day transfer to this practice for vitreoretinal surgical intervention. Pars plana vitrectomy with 25-gauge trocar-cannula systems allows transconjunctival entry, internal limiting membrane peeling under indocyanine green staining, and endolaser retinopexy for complex tractional detachment repair.
