Eye Infection Care at Monarch Medicine Urgent Care in Carmel, IN
Eye infections—particularly pink eye (conjunctivitis)—are among the most common reasons patients walk into Monarch Medicine, and one of the most important reasons to seek same-day care rather than waiting. Pink eye spreads rapidly in households, classrooms, and workplaces. Getting the right diagnosis matters because bacterial, viral, and allergic conjunctivitis each require completely different treatment—and prescribing the wrong one wastes time and delays recovery.
Our illness treatment services include same-day eye infection evaluation and treatment for patients of all ages in Carmel, IN. Walk-ins always welcome—no appointment needed.
I’m Dr. Lisa Clay, MD, FAAFP, board-certified family physician and Medical Director at Monarch Medicine. In our clinic, we see pink eye spread through families within 48 hours of the first case. Parents often come in with a child diagnosed at school and ask us to check the siblings at the same visit. That’s exactly the right call— early treatment shortens the contagious period and gets kids back to school faster.
Types of Eye Infections: How to Tell Them Apart
The treatment for an eye infection depends entirely on the cause. According to the CDC, conjunctivitis is one of the most common eye conditions in the United States, affecting millions of Americans each year. The table below shows how Dr. Clay differentiates the most common presentations during evaluation:
| Type | Key Symptoms | Contagious? | Treatment |
|---|---|---|---|
| Bacterial Conjunctivitis | Yellow or green discharge, crusting on lashes especially in the morning, red eye | Yes — highly contagious | Prescription antibiotic eye drops or ointment |
| Viral Conjunctivitis | Watery discharge, red eye, often associated with cold symptoms, may affect both eyes | Yes — highly contagious | Supportive care; antibiotics do not work for viral pink eye |
| Allergic Conjunctivitis | Intense itching, watery discharge, both eyes affected, often seasonal | No | Antihistamine drops, oral antihistamines, allergen avoidance |
| Stye (Hordeolum) | Painful red lump on the eyelid, localized tenderness, swelling | No | Warm compresses, antibiotic ointment if spreading, incision if needed |
| Keratitis (Corneal Infection) | Eye pain, blurred vision, light sensitivity, redness—often contact lens related | Varies by cause | Prescription drops, discontinue contact lens use, ophthalmology referral |
The single most important clinical distinction is bacterial vs. viral conjunctivitis. Antibiotics are effective and appropriate for bacterial pink eye—and ineffective for viral. In our experience, many patients who have been prescribed antibiotic drops for viral conjunctivitis see no improvement because the diagnosis was wrong, not because the treatment failed. A physician evaluation makes that distinction accurately.
Eye Infection Symptoms: When to Come In Same Day
Come to Monarch Medicine same day if you or your child experience:
- Yellow or green discharge from the eye—this almost always indicates bacterial infection requiring prescription treatment
- Significant redness with crusting on the eyelashes, especially after waking
- Eyelid swelling beyond mild puffiness
- Pain inside the eye (as opposed to surface irritation)
- Any change in vision, including blurring or light sensitivity
- Symptoms not improving after 24–48 hours of home care
- Contact lens wearer with any of the above—keratitis in contact lens users can progress to corneal scarring quickly
Go to the ER immediately if: You experience sudden severe eye pain, significant vision loss, chemical splash into the eye, or eye trauma with a foreign object that cannot be safely flushed. These are ophthalmic emergencies requiring specialist-level care.
How We Diagnose and Treat Eye Infections at Monarch Medicine
Dr. Clay performs a thorough external eye examination to assess discharge character, eyelid involvement, corneal clarity, and pupillary response. This clinical picture—combined with symptom history, contact lens use, and any associated illness—guides the diagnosis and treatment decision.
Treatment options available on-site at our Carmel clinic include:
- Prescription antibiotic eye drops or ointment — for confirmed or clinically suspected bacterial conjunctivitis. Ointment is often preferred for infants and young children; drops for older patients.
- Antihistamine or mast cell stabilizer drops — for allergic conjunctivitis, particularly during Indiana’s pollen seasons
- Warm compress guidance and antibiotic ointment — for styes; most resolve within 1–2 weeks with consistent warm compress application 4–5 times daily
- Contact lens discontinuation and specialist referral — any suspected keratitis requires stopping contact lens use immediately and ophthalmology follow-up, which we facilitate
- School clearance documentation — we provide written documentation for children to return to school once they are no longer contagious, typically after 24 hours of antibiotic treatment for bacterial conjunctivitis
Pink Eye in Children: What Carmel Parents Should Know
Pink eye spreads rapidly in schools, daycares, and among siblings. Our pediatric urgent care team sees children of all ages for eye infection evaluation and treatment— including infants, where eye discharge in the first weeks of life requires prompt evaluation to rule out neonatal conjunctivitis.
Per the American Academy of Pediatrics, most children with bacterial conjunctivitis can return to school 24 hours after starting antibiotic treatment. We provide school clearance letters at the time of visit—so you’re not making a separate call to get documentation that your child’s school requires.
Practical advice for preventing spread within your household once a child is diagnosed: separate towels and washcloths immediately, avoid eye touching and reinforce hand washing with younger children, and wash pillowcases daily during the infection. If a sibling develops symptoms within 24–48 hours, bring them in—pink eye moves through families quickly.
Contact Lens Wearers: Higher Risk, Faster Action Required
Contact lens wearers who develop any eye redness, pain, or discharge should remove their lenses immediately and come in for evaluation the same day. Keratitis—infection of the cornea—is significantly more common in contact lens users and can progress to permanent corneal scarring without prompt treatment.
Do not reinsert contact lenses until cleared by a physician. Bring your lens case to your visit—in some cases, culturing the case helps identify the causative organism. Dr. Clay recommends that contact lens wearers who have had keratitis switch to daily disposable lenses going forward to minimize future risk.
Preventing Eye Infections: Dr. Clay’s Recommendations
The majority of bacterial and viral conjunctivitis cases are preventable with consistent hygiene habits:
- Wash hands frequently — particularly before touching your face or eyes, and always before inserting or removing contact lenses
- Never share eye makeup, contact lenses, or eye drops — these are direct transmission vectors for bacterial and viral eye infections
- Replace eye makeup regularly — mascara and eyeliner should be replaced every 3 months; replace immediately after any eye infection
- Follow contact lens hygiene strictly — never sleep in lenses unless specifically prescribed for overnight wear, replace cases monthly, and never rinse lenses with tap water
- Use protective eyewear — during outdoor activities, yard work, or any exposure to dust, chemicals, or debris
- Avoid touching or rubbing eyes — particularly during cold and flu season when respiratory viruses that cause viral conjunctivitis are circulating

Frequently Asked Questions About Eye Infections
The most reliable indicator of bacterial conjunctivitis is thick yellow or green discharge with significant morning crusting that causes the eye to be stuck shut. Viral conjunctivitis typically produces watery discharge and is more likely to be associated with cold symptoms or recent illness. Allergic conjunctivitis is characterized by intense itching and usually affects both eyes simultaneously. A physician exam reliably differentiates these—which matters because antibiotics only work for bacterial pink eye.
Bacterial conjunctivitis is typically no longer contagious after 24 hours of antibiotic treatment. Viral conjunctivitis remains contagious for as long as symptoms are present—often 7–14 days. Most schools require 24 hours of antibiotic treatment before return for bacterial conjunctivitis. We provide school clearance documentation at the time of visit. If your child has viral pink eye, follow your school’s guidance on return timing.
Mild viral conjunctivitis and allergic conjunctivitis can sometimes be managed at home with cool compresses and OTC antihistamine drops. However, if you have yellow or green discharge, significant pain, eyelid swelling, vision changes, or symptoms not improving after 48 hours—come in. Bacterial conjunctivitis will not resolve without prescription antibiotic drops. Attempting to treat bacterial pink eye with OTC remedies delays recovery and extends the contagious period.
Yes. We provide written school clearance documentation at the time of visit for children diagnosed with conjunctivitis. For bacterial pink eye, most schools accept clearance after 24 hours of antibiotic treatment has begun. We write the documentation to match the requirements schools in the Carmel and Hamilton County area typically request so you’re not making follow-up calls to get additional paperwork.
Remove your contact lenses immediately and do not reinsert them until cleared by a physician. Contact lens wearers are at higher risk for keratitis—a corneal infection that can cause permanent vision damage if not treated promptly. Come in same day. Bring your lens case if possible. Do not wear contacts during the infection or until you’ve completed treatment and been cleared.
Yes—we’re open Saturday and Sunday 9am–12pm, and walk-ins are always welcome. Eye infections don’t wait for Monday, and getting treatment started over the weekend means your child can often return to school by Tuesday rather than missing additional days.
