conjunctivitis-causes, symptoms and treatment

Diagnostic center in Pimple Saudagar

Conjunctivitis, also named pink eye, is a delicacy of the conjunctiva, which is the slim, clear tissue that covers the white piece of the eye and lines within the eyelid. 

It can be triggered by numerous factors, including infections, allergies, and irritants.  Diagnostic center in Pimple Saudagar

Here’s an overview of the causes, symptoms, and treatment of conjunctivitis:


Bacterial Infection: Bacterial conjunctivitis is often caused by bacteria like Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenza. It can lead to yellow or green discharge from the eye. Diagnostic center in Pimple Saudagar

Viral Infection: Viral conjunctivitis is typically caused by viruses such as adenoviruses. It is highly contagious and often accompanies respiratory infections. Watery discharge and redness are common symptoms.

Allergic Reaction: Allergic conjunctivitis results from exposure to allergens like pollen, pet dander, dust mites, or certain chemicals. It can cause itching, redness, and watery discharge. Diagnostic center in Pimple Saudagar

Irritants: Exposure to irritants such as smoke, chemicals, fumes, or foreign objects can lead to irritant conjunctivitis. Symptoms may include redness, tearing, and discomfort.


Redness in the white of the eye and inner eyelids
Itchiness or burning sensation in the eyes
Excessive tearing or watery discharge
Swollen and puffy eyelids
Sensitivity to light (photophobia)
Blurred or hazy vision
Yellow or green discharge (more common in bacterial infections)
Crusty eyelids, especially upon waking (more common in bacterial infections)

The diagnosis of conjunctivitis typically involves a combination of medical history, physical examination, and sometimes additional tests. Diagnostic center in Pimple Saudagar

Here’s how the diagnosis procedure works:

Medical History: The healthcare provider will start by asking you about your symptoms, including when they started, the nature of the discomfort or discharge, and any potential triggers or exposures to irritants or allergens.

Physical Examination: The doctor will examine your eyes, eyelids, and surrounding areas. They will look for signs of redness, swelling, discharge, and other noticeable symptoms. The pattern and severity of these symptoms can often help in determining the type of conjunctivitis. Diagnostic center in Pimple Saudagar

Questioning for Differentiation: The doctor may ask specific questions to help differentiate between the various causes of conjunctivitis. For instance, they might inquire about recent exposure to sick individuals, allergic triggers, use of contact lenses, or recent irritant exposures.

Visual Acuity Test: If you’re experiencing vision changes, the doctor may perform a basic visual acuity test to assess your vision. Diagnostic center in Pimple Saudagar

Fluorescein Staining: In cases where the doctor suspects an injury to the cornea, they might use fluorescein staining. This involves putting a special dye in your eye to identify any irregularities on the surface of the eye.

Additional Tests (if necessary):

Bacterial Culture: If bacterial conjunctivitis is suspected, the doctor might take a sample of eye discharge for bacterial culture and sensitivity testing. This helps determine the specific bacteria causing the infection and its susceptibility to different antibiotics. Diagnostic center in Pimple Saudagar

Allergy Testing: If allergic conjunctivitis is suspected and the cause is unclear, the doctor might recommend allergy testing to identify potential allergens triggering your symptoms.

Viral Testing: In cases where the cause is uncertain, viral conjunctivitis can sometimes be confirmed through laboratory testing, such as polymerase chain reaction (PCR) tests that detect viral genetic material. Diagnostic center in Pimple Saudagar

Treatment: The treatment for conjunctivitis depends on its underlying cause:

Bacterial Conjunctivitis: Antibiotic eye drops or ointments are usually prescribed by a doctor to treat bacterial infections. It’s important to complete the full course of antibiotics to prevent recurrence.

Viral Conjunctivitis: Viral infections are generally self-limiting and do not respond to antibiotics. Lubricating eye drops or artificial tears can help relieve discomfort. Cold compresses may also provide relief from symptoms. Diagnostic center in Pimple Saudagar

Allergic Conjunctivitis: Avoiding allergens is the primary approach. Over-the-counter antihistamine eye drops or oral antihistamines can assist with overseeing side effects. Consult a doctor for severe cases.

Irritant Conjunctivitis: Identify and eliminate the source of irritation. Artificial tears can provide relief. If the irritation is due to chemicals, rinsing the eyes with clean water is important. Diagnostic center in Pimple Saudagar

In all cases, maintaining good hygiene, such as regularly washing hands and not touching the eyes, can help prevent the spread of conjunctivitis. 

If you suspect you have conjunctivitis, it’s recommended to consult a healthcare professional, especially if symptoms are severe, persistent, or accompanied by eye pain or vision changes. Diagnostic center in Pimple Saudagar
