For fellowship-trained glaucoma and cataract surgery in Encinitas, Quang Nguyen, MD serves as Division Head of Ophthalmology and Optometry at Scripps Clinic on Santa Fe Drive near Encinitas Community Park. Diabetic retinopathy screening and glaucoma intervention require longitudinal coordination with endocrine management, a referral loop the practice shares with San Diego Coastal Endocrinology for patients whose glycemic control directly impacts posterior segment health. The MD from the University of Southern California School of Medicine in 1992 was followed by fellowship training in glaucoma surgery and a principal investigator role in multiple national clinical trials testing new medical and surgical glaucoma treatments. Micro-invasive glaucoma surgery implant procedures, trabeculectomy, and glaucoma drainage implant placement address the full severity spectrum from early open-angle disease to refractory cases unresponsive to maximum medical therapy. Ocular allergy workups that present alongside elevated intraocular pressure intersect with the allergen immunotherapy protocols at Allergy & Asthma Medical Group when conjunctival inflammation compounds glaucoma management. The highest-complexity procedures combine femtosecond laser-assisted cataract extraction with concurrent iStent inject W trabecular micro-bypass implantation to lower intraocular pressure and remove the cataract in a single surgical session.
