This can also present with redness, vision changes, and sensitivity to light. Blepharitis is commonly caused by a bacterial infection.


As the name suggests, this condition is caused by the inflammation of the conjunctiva. Conjunctiva is the clear membrane that lines the eyelid. This could be viral or bacterial and present with the symptoms of redness of the eye, itching, burning sensation, and discharge.


This is the inflammation of the colored part of the eye which is called iris. Its cause can be viral, bacterial, or fungal. This could also be associated with injuries, trauma, and auto-immune disorders. One of the symptoms of iritis is headaches which are usually ignored.


This is the infection of the cornea. As explained earlier, the corner is the dome-shaped covering of your pupil and iris. It is caused by viruses, bacteria, fungi, or parasite but, the most common source of this infection is contact lens contamination. A large percentage of people who present with keratitis wear contact lenses.
