Conjunctivitis (Pink Eye) Treatment in the Bay Area – Causes, Symptoms & Relief Options
Conjunctivitis, commonly known as pink eye, is an inflammation or infection of the conjunctiva – the thin, transparent tissue that lines the inside of the eyelid and covers the white part of the eye.
It is a very common eye condition, especially in children, and can affect one or both eyes. While many cases are mild, some forms are highly contagious and can spread easily in schools, households, and workplaces.
What Causes Conjunctivitis?
Conjunctivitis can develop from several different causes, and identifying the type is key to proper treatment. The three main categories include:
Allergic Conjunctivitis
Triggered by allergens such as pollen, smoke, or environmental irritants. It is more common in individuals with seasonal allergies. A subtype, giant papillary conjunctivitis, can occur in contact lens wearers or from chronic eye irritation.
Infectious Conjunctivitis
- Bacterial – caused by bacteria such as staphylococcus or streptococcus, often spread through contact or poor hygiene
- Viral – commonly associated with colds or respiratory infections and spreads through coughing, sneezing, or direct contact
Chemical Conjunctivitis
Caused by exposure to irritants such as chlorine, air pollution, or harsh chemicals.
Symptoms of Pink Eye
Symptoms can vary depending on the cause but often include:
- Pink or red appearance in the white of the eye
- Itching, burning, or gritty sensation
- Excessive tearing
- Discharge from one or both eyes
- Swollen eyelids
- Sensitivity to light
Because symptoms can overlap between types, an accurate diagnosis is important.
How Conjunctivitis Is Diagnosed
Conjunctivitis is diagnosed through a comprehensive eye examination, which may include:
- Review of symptoms and medical history
- Visual acuity testing
- Examination of the conjunctiva and surrounding eye structures
- Evaluation under magnification
In more persistent or unclear cases, additional testing such as cultures may be performed to identify the cause.
Conjunctivitis Treatment Options
Treatment depends on the underlying cause and focuses on relieving symptoms, resolving infection or inflammation, and preventing spread.
Allergic Conjunctivitis
- Avoiding triggers when possible
- Cool compresses and artificial tears
- Antihistamine or anti-inflammatory eye drops
- Prescription medications for more severe cases
Bacterial Conjunctivitis
- Antibiotic eye drops or ointments
- Symptoms often improve within a few days, but the full course should be completed
Viral Conjunctivitis
- No direct cure; the infection typically runs its course over 1-3 weeks
- Supportive care such as artificial tears and cool compresses
- In some cases, medicated drops may be used to reduce inflammation
Chemical Conjunctivitis
- Immediate flushing of the eye
- Medical evaluation, especially for more serious exposures
Contact Lens Considerations
If you wear contact lenses, you may need to stop wearing them temporarily during treatment. Your doctor may also recommend changes to your lens type or cleaning routine to prevent recurrence.
Preventing the Spread
Good hygiene is essential, especially for contagious forms:
- Wash hands frequently
- Avoid touching or rubbing the eyes
- Do not share towels, makeup, or eye products
- Replace eye cosmetics such as mascara
- Follow proper contact lens care
