Gonorrhea in the eye is conjunctivitis caused by the bacterium Neisseria gonorrhoeae reaching the eye, usually when a person touches genital fluids and then their eye (autoinoculation), or when a newborn passes through an infected birth canal. It causes thick discharge, swelling, and redness, needs prompt antibiotic treatment, and can threaten sight if ignored.

The essentials: how gonorrhea gets into an eye
Gonococcal conjunctivitis is the same organism that causes genital, rectal, and throat infection, lodged in the conjunctiva, the thin membrane lining the eyelid and covering the white of the eye. In adults it most often happens by autoinoculation: someone with a genital, rectal, or throat infection gets infected fluid on a finger and rubs an eye. Many people with gonorrhea have no symptoms, so they may not know they're carrying it when it spreads to the eye CDC.
In newborns the route is different. A baby born to a mother with untreated cervical gonorrhea can pick up the bacteria during delivery, producing ophthalmia neonatorum, a severe eye infection that appears in the first days of life. This is why every newborn in the US routinely gets antibiotic eye ointment at birth, and why prenatal screening for the infection matters.
Gonococcal eye infection is more aggressive than ordinary pink eye. The bacterium can invade the cornea, and untreated infection can scar or perforate it. Get same-day care.
Symptoms of gonorrhea in the eye
The hallmark is a copious, thick, pus-like discharge, often described as hyperacute (fast-moving) conjunctivitis. Symptoms tend to come on quickly and look more dramatic than viral or allergic pink eye.
- Heavy yellow-green discharge that keeps returning within minutes of being wiped away.
- Marked redness of the white of the eye and the inner eyelid.
- Swelling of the eyelids, sometimes severe enough that the eye is hard to open.
- A gritty, foreign-body sensation, watering, and sensitivity to light.
- Pain or blurred vision can signal corneal involvement and needs urgent eye care.
In a newborn, watch for red, swollen lids and thick discharge in the first days after birth. Because the same organism causes infection elsewhere, an adult with eye symptoms often has, or recently had, a urogenital, rectal, or throat infection too, even without noticing it. For context on the underlying infection's genital and throat symptoms, see our gonorrhea overview.
Testing: confirming it's gonorrhea, not ordinary pink eye
Hyperacute purulent conjunctivitis is treated as gonococcal until proven otherwise, but laboratory confirmation guides care. A clinician swabs the discharge for testing. The nucleic acid amplification test (NAAT) is the preferred method, with sensitivity usually above 90% and specificity around 99% CDC STI guidelines. Culture is also valuable here because it allows antibiotic-susceptibility testing, useful given rising resistance.
Because eye infection usually means the bacterium is somewhere else too, a thorough workup also tests every site of sexual exposure: a first-catch urine or vaginal swab, plus throat and rectal swabs if you've had oral or anal sex. Ask for each exposed site by name, since an untested site is a missed infection. Patient-collected swabs are acceptable. If you're unsure how soon a test turns positive, read when to test after exposure, and you can get tested at a clinic that handles all anatomic sites.
The urine sample is simple, and the swabs are quick. The bigger mistake is forgetting to mention oral or anal sex, which leaves a throat or rectal infection undiagnosed along with the source of the eye infection.
Treatment: how gonococcal eye infection is cured
Gonorrhea is curable, but medicine can't reverse damage already done to the cornea, so speed matters. The backbone of treatment is ceftriaxone given by injection. For uncomplicated infection, the CDC recommends ceftriaxone 500 mg in a single intramuscular dose for people under 150 kg, and 1 g for those 150 kg or more MMWR, 2020. Eye infection is treated as more than uncomplicated; clinicians often add saline irrigation to flush the discharge and may use higher or repeated dosing under specialist guidance. This is managed in person, not with take-home pills.
If a chlamydial infection hasn't been ruled out, doxycycline 100 mg twice daily for 7 days is added, because the two infections travel together. The 2020 guidelines moved gonorrhea from dual therapy (ceftriaxone plus azithromycin) to ceftriaxone alone, with the dose raised from 250 mg to 500 mg. Azithromycin was dropped over antimicrobial-stewardship concerns and rising reduced susceptibility, with isolates showing elevated azithromycin MICs climbing from 0.6% in 2013 to 4.6% in 2018.
For a documented cephalosporin allergy, the alternative is gentamicin 240 mg IM plus azithromycin 2 g orally, both single doses. If ceftriaxone simply isn't available, cefixime 800 mg orally is an option for urogenital and anorectal infection only; it doesn't reliably clear the throat, and a test-of-cure is advised after it. Two oral antibiotics from entirely new classes, zoliflodacin (Nuzolvence) and gepotidacin (Blujepa), were FDA-approved on December 12, 2025 for uncomplicated urogenital gonorrhea FDA. Neither replaces ceftriaxone as first-line; they're held in reserve for resistance. Full regimens and doses live on our gonorrhea page.
After treatment, partners from the prior 60 days should be notified and treated, and you abstain from sex for 7 days after the shot so you don't pass it back and forth. Retest about 3 months later, because reinfection is common. If you also had throat infection, a test-of-cure 7–14 days after treatment is recommended, since the pharynx is harder to clear than other sites.
Standard of care vs. reserve options
| Regimen | Route | When it's used |
|---|---|---|
| Ceftriaxone (500 mg, or 1 g if ≥150 kg) | Injection (IM) | First-line for all sites |
| + Doxycycline (100 mg twice daily, 7 days) | Oral | Added if chlamydia not excluded |
| Gentamicin + azithromycin | Injection + oral | Cephalosporin allergy |
| Cefixime (800 mg) | Oral | If ceftriaxone unavailable; not for throat; needs test-of-cure |
| Zoliflodacin / gepotidacin | Oral | Reserve for resistance; not first-line |
Prevention
Since adult eye infection comes from fluid reaching the eye, hand hygiene matters: don't touch your eyes after contact with genital fluids, and wash your hands. Preventing the genital infection prevents the eye infection. Correct, consistent condom use; mutual monogamy with a tested partner; and regular screening of every exposed site are the proven tools, covered in how to prevent gonorrhea.
DoxyPEP, a dose of doxycycline taken within 72 hours of sex, cuts chlamydia and syphilis by more than 70%, but it's much less effective against gonorrhea, and the CDC does not recommend it specifically for gonorrhea prevention, partly out of concern about driving tetracycline resistance CDC DoxyPEP, 2024. For newborns, routine antibiotic eye ointment at birth plus prenatal screening and treatment of the mother prevent ophthalmia neonatorum.
When to see a clinician
Treat sudden, heavy, pus-like eye discharge as urgent, with same-day care, ideally an eye specialist, because corneal involvement can threaten sight. Other reasons not to wait:
- Eye pain, blurred vision, or light sensitivity alongside discharge.
- A newborn with red, swollen lids or thick discharge in the first days of life.
- A swollen, painful testicle, which can mean epididymitis (inflammation of the tube behind the testicle that can affect fertility) and needs prompt care.
- Fever, joint pain, or skin sores, which can signal disseminated gonorrhea, bacteria spreading through the bloodstream.
Care is widely accessible: gonorrhea testing and treatment are free or low-cost at public clinics, and the injection is given on-site.
