Examining Changes in Vision and Eye Health

Examining Changes in Your Vision and Eye Health

Our eyes provide a unique window into overall wellness. Subtle visual shifts can signal normal aging, underlying health conditions, or serious eye disease. Learning key symptoms provides vital clues to assess when changes seem harmless, need further evaluation, or require emergency care.

Knowing Your Baseline Vision

Routine eye exams help establish baseline vision and eye health. Report any new, different, or concerning symptoms you notice in between exams as well. Catching subtle early changes allows timely treatment to prevent permanent damage.

Those with pre-existing conditions like diabetes, hypertension, autoimmune disorders, or high prescription also need diligent monitoring to avoid vision threatening complications.

Floaters and Flashes

Small specks drifting across your field of vision are floaters. Lightning streaks or dark arcs are flashes. Most happen due to age-related changes and are harmless. But new persistent floaters or flashes may indicate:

• Posterior vitreous detachment - gel pulling away from retina
• Retinal tear - thin lining pulling away
• Retinal detachment - torn lining separating from back of eye

Seek prompt evaluation if accompanied by sudden increase in spots, dense haze, vision loss, or curtain-like obstruction which could signal urgent retinal detachment.

Halos and Starbursts

Seeing halos or starburst patterns around lights typically stems from corneal dryness or swelling. Other common causes include:

• Refractive error like nearsightedness/farsightedness
• Corneal injury or infection
• Cataracts
• Glaucoma

Schedule an eye exam to determine the cause, especially if symptoms seem to flare or worsen suddenly.

Light Sensitivity and Blurred Vision

Increased sensitivity to light, pain, and blurred vision can arise from:

• Dry eyes
• Allergies
• Pink eye
• Inflammation
• Migraine
• Medication side effects

Evaluate environments for factors aggravating symptoms. See an optometrist or ophthalmologist if no relief within 1-2 weeks.

Double Vision (Diplopia)

Diplopia, or ghosting of images, often results from eye misalignment issues like:

• Strabismus - crossed/wandering eye
• Amblyopia - lazy eye
• Astigmatism - blurred vision

But it can also signal:

• Mini-stroke
• Multiple sclerosis
• Brain tumor
• Nerve palsy

Promptly consult an ophthalmologist if double vision arises suddenly, is constant, affects central vision, or occurs without clear refractive cause.

Shadows, Missing Sections, and Color Loss

Any new shadows, blurry spots, missing sections within your visual field, or washed out color perception warrant urgent evaluation. Potential causes include:

• Retinal holes, tears, or detachments
• Vitreous detachment
• Scar tissue
• Macular degeneration
• Glaucoma
• Diabetic retinopathy
• Stroke
• Brain tumor

Catching these vision threatening conditions quickly maximizes chances of reversing damage before it becomes permanent.

When to Seek Emergency Care

Call 911 or visit an emergency room promptly for symptoms like:

• Sudden loss or severe decrease in vision
• Dramatic increase in floaters or flashes
• Veil or curtain appearing across vision
• One pupil larger than the other
• Persistent double vision
• Unremitting pain behind or around the eye

Rapid evaluation and treatment within hours is critical for best outcomes with acute vision threatening diagnoses. Don't delay seeking emergency medical care if experiencing these sight-stealing red flags.

Protect Your Sense of Sight

Attend annual eye exams, know your risk factors, and speak up about new or worsening symptoms to help safeguard vision. With vigilant monitoring and timely response, concerning changes can often be addressed effectively.
