Old Age Vision Problems

With time, old age vision problems such as blurred or double vision, colour or night blindness, dry or watery eyes, redness or swelling of an eye are experienced by many. The following are brief descriptions of just some of the afflictions.

Presbyopia

This is the loss of the ability to see close objects, a normal effect of the aging process. Closer objects appear blurred due to the aging and hardening of the lens, usually occurring after the age of 40. Glasses help to correct the defect and a vitamin rich diet can prevent macular degeneration or a worsening of the problem.

Cataracts

These are cloudy spots that develop in the eye lenses with age, resulting in blurred vision. If the cataracts grow, they can cause pain and redness and may lead to a significant reduction in vision. The problem is normally corrected by cataract surgery.

Glaucoma

This is the result of too much fluid pressure within the eye, which can result in total vision loss if not treated swiftly. Fluid pressure inside the eye increases when the watery fluid between the cornea and the lens gets blocked. Eye drops, lasers or surgery may be the treatment options used.

Floaters

Floaters are one of the commonest vision problems due to aging. They are usually noticeable as small specks or cobweb type shapes that may disappear naturally, or risky surgery may be performed, with varying results.

Dry Eyes

Dryness is experienced when the tear glands malfunction, resulting in an itching or burning sensation. Women are more susceptible to the problem. Eye drops or ointments may be prescribed, but more severe bouts may require the use of special contact lenses.

Watery Eyes

Caused by constant tearing, that may be due to light, wind or temperature sensitivity. Goggles may prevent irritation but excessive tearing may be caused by an eye infection or blocked tear glands, so it is essential to seek medical advice.

Retinal Disorders

Regular check ups are the way to identify age-related retinal problems. A detached retina is a serious condition that requires immediate attention. A sudden increase in eye floaters or flashes should be the trigger to take professional advice.

This list is by no means exhaustive, but it is clear that eye care is vital, particularly with aging. A healthy diet and regular checkups can help prevent old age vision problems.

Eye problems or eye pain should never be neglected.

Retinal Detachment Symptoms

Located in the retina are cells that are sensitive to light and some that pass nerve impulses to the brain. If the retina detaches from the back of the eye, vision is severely affected. There are various reasons why detachment occurs such as injury to the eye, myopia (short-sightedness), eye surgery, diabetic retinopathy, glaucoma or eye tumours. Given that retinal detachments can seriously impair vision, it is vital that professional medical attention is provided immediately, if any of the following retinal detachment symptoms are experienced. Symptoms may include flashes, floaters, shadows that affect peripheral vision and a curtain effect across the field of vision.

Flashing Lights

Flashes are impressions of bright lights at the field of vision border, normally affecting one eye at a time. When the vitreous humour, the clear gel within the eyeball shrinks or tugs the retina, the resulting pressure applied to the retina nerve cells causes the flashes. If the pulling is strong enough, the retina can detach or tear. A visit to the relevant medical professionals is essential if these flashes increase in number or incidence.

Floaters

Floaters are tiny black dots, lines or cobweb-like shapes that may appear in the field of vision. This debris floats around in the vitreous humour. If the floaters increase in number or if floater numbers increase added to new flashes, an eye examination should be carried out immediately, as these symptoms indicate an increased chance of a retinal tear or detachment.

Field Of Vision Changes

If the retina detaches from the back of the eye, changes to the field of vision will occur that correspond to the area of the retina affected. This frequently will resemble a curtain or shadow moving into the field of vision, usually entering from the top or from the side. Once again, if these symptoms are experienced, an immediate eye assessment is vital.

Although rare, a retinal detachment may occur without warning, so any signs of sight impairment should be investigated.
