Geriatric Optometry: Ageing Eye Changes, Prescribing for Older Adults and Falls

Last updated: November 2026

RPC Rounds for Optometrists · B.Optom study guide

India's older population is growing fast, and most of them need regular eye care. Older adults have more eye disease, more medicines, more falls and more difficulty communicating. Good geriatric optometry means detecting disease early, prescribing in a way that keeps them safe, and adapting the examination to the person.

Normal ageing changes

Structure	Change	Effect
Lids	Laxity, dermatochalasis, ptosis, ectropion or entropion	Field restriction, watering, exposure
Tear film	Less tear production, meibomian gland dysfunction	Dry eye symptoms
Cornea	Arcus, reduced endothelial cell count	Usually harmless; arcus under 50 years needs lipid check
Pupil	Senile miosis	Less light reaches the retina: older eyes need about 2–3 times more light
Lens	Presbyopia, yellowing, cataract	Near blur, reduced contrast, glare, myopic shift (nuclear cataract)
Vitreous	Syneresis, posterior vitreous detachment	Floaters and flashes (check for tears)
Retina and optic nerve	Fewer photoreceptors and ganglion cells	Slower dark adaptation, reduced contrast sensitivity

Diseases to look for at every visit

Cataract, glaucoma (IOP, discs, fields), age-related macular degeneration (Amsler grid, macula), diabetic and hypertensive retinopathy, and vascular occlusions.
Giant cell arteritis in anyone over 50 with sudden vision loss, headache or jaw pain: same-day referral.
Medication effects: hydroxychloroquine, tamsulosin (floppy iris before cataract surgery), steroids, antihistamines and anticholinergics (dry eye, angle closure risk).

Prescribing and dispensing for older adults

Small, careful changes: older adults adapt slowly. Avoid large changes in cylinder axis or power and in lens form unless vision gains are clear.
Falls risk: multifocals (bifocals, progressives) blur the ground when walking and increase fall risk in frail people. Consider single-vision distance glasses for walking outdoors and separate reading glasses.
Lighting and contrast: advise brighter task lighting, anti-glare measures and high-contrast marking on steps.
Lightweight, easy-to-handle frames; larger reading zones; magnifiers for low vision.
Second eye cataract surgery and anisometropia: plan for temporary glasses or contact lenses between operations.

Adapting the examination

Allow more time; check hearing and speak clearly facing the patient; involve carers when helpful.
For people with dementia or after stroke, use objective methods (retinoscopy, autorefraction, fundus photographs) and simple tests; consider domiciliary (home) visits.
Ask about driving and recommend that vision meets licensing standards; check visual fields if glaucoma or stroke is present.

Practical pearls

For a frail older person who has fallen, ask "Do you wear varifocals when you go out walking?" and offer single-vision glasses for outdoors.
A sudden myopic shift in an older adult is usually nuclear cataract, but check blood sugar too.
Always check the second eye: patients with one blind eye from AMD or glaucoma need careful protection of the other.

Where students slip

Prescribing a big cylinder change to an 80-year-old who was happy with the old glasses.
Missing giant cell arteritis because the patient blamed "tired eyes".
Ignoring lighting advice, which often helps more than a new prescription.
