The function of Lid in our body is very composite and complex. It is one of the vital structures in our system. For proper functioning of lid requires both a constant flow of fluids, as well as physiological maintenance. Any disruption in its mechanism would result in disease, pain and the possibility of minor complications. The most important function of lid is to shield the eye from trauma. This function is mainly achieved through closing of the eye. During this mechanism the lashes also play a role as they catch waste, and notify us when something is too close to our eyes. Apart from these functionalities they also house many glands that secrete fluids that cleanse our eyes and keep them damp.

Infection in lid is mainly caused by the clogged gland of the lid often referred as stye. Generally, the infection is seen as a red tender bump in the lid. At times, it seems like a small pimple on the lid. Blepharitis is another lid infection which is an inflammation of the lid, and emerges as a red lid margin with debris on the surface. This infection often results in dryness or redness in the eye, in addition to general discomfort of the eye. To relieve from this illness you’ll require proper treatment.

Dacryocystitis is one of the serious conditions of the lid area which is caused by infection of the nasolacrimal sac. The section between the inner and outer corner of the eye lid and nose is where it lies. This condition is mainly caused by the blockage of the duct that permits tears to flow. The infection result in pain, redness, excessive tearing and at times even swelling of the inner most area of the lid. Often, the blocked tear duct becomes infected with bacteria like Staphylococcus aureus, Streptococcus pneumoriae and Pseudomonas.

Most patients suffering from lid infections feel very uncomfortable and present swollen red inner eye lid. During its treatment factors like the pain, redness and swelling as well as puss in the infected area are all taken into consideration.
