Geriatric Syndrome
Vision Impairment in Older Adults: Workup
Vision impairment affects roughly 1 in 4 adults over 70 and is a major contributor to falls, fractures, depression, social isolation, medication errors, driving cessation, and accelerated cognitive decline. The four leading causes — cataract, age-related macular degeneration (AMD), glaucoma, and diabetic retinopathy — are all detectable on routine screening and most are treatable when caught early. This guide covers in-clinic vision screening (Snellen chart, near vision card, Amsler grid), distinguishing the four major causes by symptom pattern, when to refer to ophthalmology urgently (sudden vision loss, painful red eye, halos, flashes, floaters) versus routinely, and the role of the optometrist for refractive error and low-vision evaluation. Includes home safety modifications for low vision (lighting, contrast, glare reduction), assistive technology, and connecting patients to state services for the visually impaired.

Assessment
How to identify in clinic
- Ask: "Do you have trouble reading, watching TV, or recognizing faces?"
- Snellen chart — screen at annual wellness visit
- Near vision card — test with usual reading glasses
- Observe: squinting, holding papers close, difficulty navigating office
Common causes in older adults
- Cataracts — most common, gradual onset, treatable with surgery
- Age-related macular degeneration (AMD) — central vision loss
- Glaucoma — peripheral vision loss, often asymptomatic until late
- Diabetic retinopathy — requires annual screening
- Refractive error — most easily corrected
Impact on geriatric syndromes
- Doubled fall risk
- Medication errors (can't read labels)
- Social isolation and depression
- Driving safety — assess fitness to drive
- Mistaken for cognitive impairment
Management
Non-pharmacologic
- Updated refraction / corrective lenses — first step
- Large-print materials, magnifying devices
- Adequate lighting in home — especially stairs, bathroom
- High-contrast labels on medications
- Occupational therapy for low vision rehabilitation
- Cataract surgery referral — safe and highly effective even in very old patients
Condition-specific treatments
- Cataracts → ophthalmology referral for surgery evaluation
- Wet AMD → intravitreal anti-VEGF injections (ophthalmology)
- Glaucoma → topical prostaglandin analogs (e.g., latanoprost)
- Diabetic retinopathy → optimize glucose + ophthalmology
Avoid
- Anticholinergics — worsen glaucoma (narrow-angle)
- Corticosteroids — can worsen cataracts and glaucoma
Refer & Document
When to refer
- Ophthalmology — any significant visual acuity change, cataracts, AMD, glaucoma
- Optometry — routine refraction if no pathology suspected
- OT — low vision rehabilitation for functional adaptation
- DMV notification — if vision impairs driving safety (state-dependent)
Documentation must include
- Visual acuity (Snellen result)
- Last eye exam date
- Known eye conditions
- Functional impact (reading, driving, medication management)
- Referral plan
- Driving safety assessment
Clinical Pearl
Bifocal and multifocal lenses increase fall risk in older adults by impairing depth perception when looking down (stairs, curbs). For patients with significant fall risk, consider single-vision lenses for walking and separate readers for close work.
