Symptoms of Pink Eye(Conjunctivitis)

There are some common signs that you may experience if you have this condition.

• Redness: One of the most noticeable symptoms of conjunctivitis is redness in the affected eye. The white part of the eye may appear pink or red, and the blood vessels in the eye may be more visible than usual.
• Itching: Conjunctivitis can also cause itching or a sensation of something in the eye. You may feel the need to rub your eye frequently, which can further irritate the eye and spread the infection.
• Discharge: Another common symptom of conjunctivitis is discharge from the eye. The discharge may be watery or thick and yellow or green in color. If the discharge is thick and sticky, it may cause the eyelids to stick together, especially after sleeping.
• Sensitivity to light: Conjunctivitis can also cause sensitivity to light. This means that bright lights or sunlight may be uncomfortable or painful for your affected eye.
• Blurred vision: In some cases, conjunctivitis can cause blurred vision, especially if the discharge from the eye is blocking your vision.
• Swelling: Conjunctivitis can also cause swelling of the eyelids, making them feel heavy and uncomfortable. This can make it difficult to open or close your eyes.
• Foreign body sensation: Conjunctivitis can cause a sensation of having a foreign body or something stuck in the eye. This can be a sign of conjunctivitis caused by an allergic reaction.

Conjunctivitis can be caused by bacteria, viruses, allergies, or other irritants, and the treatment will depend on the underlying cause. In some cases, conjunctivitis can be highly contagious, so it is important to take precautions to prevent spreading the infection to others."

Causes and types of Pink Eye(Conjunctivitis)

There are several causes of conjunctivitis, including viral, bacterial, and allergic reactions. Understanding the different types of conjunctivitis and their causes can help you take the necessary steps to prevent and treat this condition.

(1) Viral Pink Eye(Conjunctivitis):

Viral conjunctivitis is the most common type of conjunctivitis and is caused by a virus. If tears or water from the eyes of an infected person enters the eyes of a healthy person, then he can also get this disease. This disease mostly spreads to the other eye within a few days after first being in one eye. Its symptoms include redness in the eyes, itching and discharge from the eyes. 

(2) Bacterial Pink Eye(Conjunctivitis):

Bacterial conjunctivitis is caused by bacteria and is often characterized by a thick discharge from the eye. It can be caused by a variety of bacteria, including staphylococcus and streptococcus.

 

(3) Allergic Pink Eye(Conjunctivitis):

Allergic conjunctivitis is caused by an allergic reaction to a substance, such as pollen, dust, or pet dander. Its symptoms include redness in the eyes, itching and discharge from the eyes.  Unlike viral and bacterial conjunctivitis, allergic conjunctivitis is not contagious.

(4) Other Causes:

Conjunctivitis can also be caused by other factors, such as exposure to irritants like smoke, chlorine, or pollution, as well as contact lens wear, and certain medications.

Treatment for Pink Eye(Conjunctivitis)

Conjunctivitis can be treated with a variety of methods, depending on the underlying cause. Here are some of the most common treatments for conjunctivitis:

1. Antibiotics: If the cause of conjunctivitis is bacterial, antibiotics may be prescribed to kill the bacteria. Antibiotic eye drops or ointments can be used to treat the condition. It is important to follow the prescribed dosage and frequency of use to ensure the effectiveness of the medication.
2. Antiviral medication: If the conjunctivitis is caused by a virus, antiviral medication may be prescribed. However, most cases of viral conjunctivitis will resolve on their own without the need for medication.
3. Allergy medication: If the cause of conjunctivitis is an allergy, antihistamines or mast cell stabilizers may be prescribed to reduce the allergic reaction. These medications can be taken orally or applied as eye drops.
4. Warm compresses: To relieve symptoms such as itching and swelling, warm compresses can be applied to the affected eye. This can be done by soaking a clean cloth in warm water and placing it over the closed eye for several minutes.
5. Artificial tears: Artificial tears can be used to lubricate the eye and relieve dryness and irritation caused by conjunctivitis. These eye drops can be purchased over-the-counter and can be used as needed throughout the day.

In severe cases, the doctor may conduct tests like blood test etc. of the patient.
