Low Vision

Low vision means sight that remains reduced even with the right glasses, contact lenses, medicine or surgery, to a degree that interferes with daily tasks such as reading, recognising faces or getting around. It is not total blindness: most people with low vision have useful sight that can be put to better use.

Low vision is the result of another eye or brain condition, so care has two strands. The first is making sure the underlying disease is treated as well as it can be. The second is rehabilitation: magnification, lighting, contrast, technology and training that help you do what matters to you. Rehabilitation improves function; it does not restore the lost sight.

Symptome

• Difficulty reading ordinary print even with glasses
• Trouble recognising faces across a room
• A blurred or missing patch in the centre of vision
• Loss of side vision, bumping into things
• Problems with glare and with moving between light and dark
• Colours looking faded and steps or kerbs hard to judge
• Seeing patterns or figures that are not there (Charles Bonnet syndrome), which is a recognised effect of sight loss and not a mental illness

Ursachen und Risikofaktoren

In adults the leading causes are age-related macular degeneration, diabetic retinopathy, glaucoma, untreated cataract, inherited retinal diseases such as retinitis pigmentosa, optic nerve disease, severe short-sightedness with retinal damage and stroke affecting the visual pathway. In children, causes include albinism, congenital cataract, retinopathy of prematurity, optic nerve underdevelopment and brain-related visual impairment. Central loss mainly affects reading and faces; peripheral loss mainly affects mobility.

Wie es diagnostiziert wird

• Full eye examination: Confirms the cause and checks whether anything treatable, such as cataract or macular swelling, has been missed.
• Careful refraction: Even a modest improvement from updated glasses can matter a great deal when vision is limited.
• Functional vision assessment: Measures reading speed, print size, contrast sensitivity and glare, rather than only letters on a chart.
• Visual field testing: Maps blind spots and shows whether the loss is central or peripheral, which guides the choice of aids.
• OCT and retinal imaging: Documents the state of the macula and optic nerve and monitors the underlying disease.

Behandlungsmöglichkeiten

• Treating the underlying disease: Injections for wet macular degeneration and diabetic macular swelling, pressure control in glaucoma, and cataract surgery where it would help.
• Optical magnifiers: Hand and stand magnifiers, high-power reading glasses and small telescopes, chosen and trialled for a specific task.
• Electronic magnification: Video magnifiers, tablets and phone apps that enlarge, change contrast and read text aloud.
• Lighting, contrast and glare control: Task lamps, tinted filters, large-print and high-contrast marking at home.
• Eccentric viewing and scanning training: Teaches you to use a healthier part of the retina or to scan into a blind area.
• Orientation and mobility training: Long cane skills and route learning for people with significant field loss.
• Emotional support: Sight loss commonly brings low mood and anxiety. Counselling and peer groups are part of proper care.

Wenn es dringend ist

Sudden loss of vision, a curtain or shadow, new distortion of straight lines, or sudden flashes and floaters are emergencies and need an eye examination locally the same day. They are not part of stable low vision and should not be left for a planned visit.

A visit can provide a thorough review of the diagnosis, a check that nothing treatable has been overlooked, and a low vision assessment where devices are tried and prescribed over 2 to 3 appointments. Training, home adaptations, registration for local benefits and schooling support for children depend on services where you live. Be cautious of any offer of stem cell or other regenerative treatment for retinal or optic nerve disease: outside regulated clinical trials these are unproven.
