A Pennsylvania College of Optometry graduate who interned at Johns Hopkins Eye Clinic, Ryan Hosn opened his Lake Murray Boulevard practice in La Mesa in 2018 after managing over fifty optometrists across thirty LensCrafters locations as a regional director. The practice's comprehensive diabetic eye-screening protocol generates referral coordination with primary-care physicians including Andrew Brown, MD at SharpCare Grossmont, where dilated-fundus findings feed back into each patient's metabolic management plan. Bausch + Lomb Lens Consultant and Speaker credentials supplement advisory-board positions at both Alvarado Eye Clinic and NVISION Laser Center, providing a surgical referral pathway for patients diagnosed with cataracts, glaucoma, or corneal disease beyond optometric scope. Bilingual service in Arabic and English and geriatric vision-screening capability extend the Lake Murray corridor's preventive-care reach to aging populations coordinated through La Mesa residential facilities such as Arbor Hills Nursing Center. The practice's highest-acuity diagnostic cases involve retinal imaging for early-stage macular degeneration detection, where optical coherence tomography differentiates drusen deposits from neovascular membrane formation to determine the urgency of ophthalmologic referral.
