Deaner-Harring Sherry D OD practices optometry at Chula Vista's Eye Physicians Medical Surgical Center on Third Avenue, a comprehensive eye care facility serving the community since 1957 alongside board-certified ophthalmologists. The optometric scope covers routine refractive exams, contact lens prescriptions, and preliminary diagnostic workups that feed into the surgical pipeline for cataract, glaucoma, and retinal procedures, complementing the Third Avenue Village health corridor where Naples Dental on Third Avenue addresses the oral health side of systemic conditions that simultaneously affect ocular vasculature. Dry eye syndrome evaluations include Schirmer strip tear production measurement and fluorescein staining to grade corneal epithelial compromise before initiating cyclosporine or lifitegrast therapy. Patients experiencing chronic eye strain compounded by upper-trapezius and suboccipital tension from screen-intensive work may coordinate complementary acupuncture treatment at Urban Sage Acupuncture + Wellness to address the musculoskeletal component of their visual fatigue. Visual field perimetry using Humphrey automated threshold testing maps scotoma boundaries and nerve fiber bundle defects to stage glaucoma severity before the center's surgeons determine intervention timing.
