Signs Your Eye Infection Needs Urgent Attention

Most eye infections are harmless in the long run, but that doesn’t mean they should be ignored. Getting the right diagnosis from an eye doctor can speed up healing, stop the spread to others, and, most importantly, prevent serious complications including vision loss in severe cases. At ReFocus Eye Health in Philadelphia, we provide expert emergency eye care for patients from Meriden, Southington, Wallingford, and nearby communities, ensuring you get the prompt treatment your eyes deserve.

Eye Infections from Contact Lenses: What You Need to Know

Contact lens wearers are at a higher risk of developing certain types of eye infections, particularly bacterial and parasitic keratitis. Improper lens hygiene, sleeping in contacts, and exposure to contaminated water sources can all introduce harmful microbes that infect the cornea. These contact lens-related eye infections can progress rapidly, causing severe pain, vision loss, and even blindness if not treated promptly by an eye doctor. Following strict contact lens cleaning and replacement protocols, avoiding risky behaviors like swimming in contacts, and seeking immediate medical attention for any eye irritation or changes in vision are crucial for contact lens wearers to prevent these sight-threatening conditions.

Eye Infections in Babies & Young Children: Signs, Risks, and Care

Eye infections are particularly concerning in young children, who may be unable to effectively communicate their symptoms or refrain from touching or rubbing their eyes. Common pediatric eye infections include bacterial and viral conjunctivitis (pink eye), which can spread easily in daycares and schools. Children with compromised immune systems or those who have recently undergone eye surgery are also at higher risk for more serious infections. Parents should be watchful for signs of eye redness, discharge, pain, or light sensitivity in their children and promptly consult an eye doctor, as timely treatment is essential to prevent complications like vision loss or permanent eye damage in this vulnerable population.

What Causes Eye Infections & Who’s at Risk?


Why Early Diagnosis Matters

Timely diagnosis and treatment by an eye doctor is crucial to prevent complications and vision loss from eye infections. An eye doctor will:

  • Take a detailed medical history
  • Examine the eyes with a slit lamp microscope
  • Evaluate the cornea, tear film, eyelids and more
  • Test visual acuity and eye pressure
  • Culture discharge samples to identify infectious agents
  • Perform corneal scrapings or biopsies if needed
  • Use special dyes or imaging to check for eye damage

Effective Treatment for Faster Healing

Treatment depends on the specific type of eye infection diagnosed, but may include:

  • Prescription antibiotic, antiviral or antifungal drops
  • Oral medications to fight infection
  • Frequent artificial tears to flush microbes
  • Steroid drops to quell inflammation
  • Removing contact lenses until healed
  • Surgical procedures to repair corneal ulcers or perforations

Close monitoring by an eye doctor is essential to ensure the infection improves as expected. In resistant or severe cases, treatment may require multiple medications or prolonged therapy.

What Happens If an Eye Infection Goes Untreated?

Eye infections can progress rapidly, leading to sight-threatening complications:

  • Corneal ulcers and scarring
  • Chronic or recurrent infections
  • Perforated cornea requiring transplant
  • Inflammation inside the eye (uveitis or endophthalmitis)
  • Irreversible vision loss or blindness

This underscores the importance of seeking prompt care from an eye doctor at the first signs of infection. With proper treatment, most people recover fully.

  • Avoid sharing personal items like towels, makeup, or eye drops to reduce contamination.
  • Follow proper contact lens care clean them as directed and replace them on schedule.
  • Never sleep in your contacts unless specifically approved by your doctor.
  • Toss out old eye makeup, especially if you’ve had an eye infection.
  • Protect your eyes in water wear goggles in pools and hot tubs, and avoid swimming in contacts.
  • Shield your eyes from harm with sunglasses or protective eyewear when needed.
  • Stay on top of your eye health with regular check-ups from your eye doctor.

When to Refer a Patient to an Eye Specialist

As a healthcare professional, knowing when to refer a patient to an eye doctor can make all the difference in preventing serious complications. Consider referral if a patient has:

  • Eye symptoms that don’t improve within 24 hours of treatment
  • Heavy discharge or eyelids stuck shut
  • Corneal ulcers, lesions, or other signs of corneal involvement
  • Intense pain, significant redness, or noticeable swelling
  • Blurry vision, double vision, or visual field changes
  • Signs of infection after recent eye surgery or trauma
  • Possible orbital cellulitis or shingles affecting the eye
  • A newborn with conjunctivitis, which can lead to blindness if untreated

Collaborating with an eye specialist ensures timely and appropriate care for infections and urgent eye conditions. Early referral can be the key to preventing long-term damage and preserving vision.
