Jeffrey W. Gregg, OD is an optometrist at Grossmont Center in La Mesa, practicing from Suite 210 on Grossmont Center Drive within the Grossmont medical and retail campus. The practice scope extends beyond routine refraction to include YAG laser capsulotomy for secondary cataracts, diabetic retinopathy screening, and glaucoma management — systemic conditions also flagged during periodontal evaluations at dental providers in the same complex such as Dentists of Grossmont. Comprehensive eye health examinations incorporate contact lens fitting, macular degeneration monitoring, and conjunctivitis treatment across pediatric through geriatric patient populations. Therapeutic pharmaceutical prescriptions for conditions including bacterial keratitis and allergic conjunctivitis fill at campus pharmacies such as Sharp Grossmont Hospital Pharmacy. The highest-complexity evaluations involve optical coherence tomography scanning of the retinal nerve fiber layer for pre-perimetric glaucoma detection at micron-level resolution.
