This is a common eyelid pump among adults, but the problem with this eyelid pump is that it can create complications if left untreated. This condition is otherwise called as meibomian cyst and it is a type of localized, fluid-filled bump on the lower or upper eyelid. These bumps are sometimes confused with that of styes. But, these two problems are different from each other.
A sty, which is otherwise called as hordeolum is a painful and red lump at the base of the eyelashes. This is generally caused due to bacterial infection on an eyelid oil gland. On the other hand, Chalazion, which is pronounced as Ka-Lay-Zee-Un is a firm and generally painless nodule that develops within the eyelid and it occurs when the oil gland becomes blocked or obstructed. But, a sty that is present inside the eyelid can turn into a chalazion, if it does not heal properly. Even, a meibomian cyst can become infected and can produce a sty. Even though, this condition is common, the actual prevalence of cyst in the eyelid is now known. It is generally common in adults between the age group of 30 and 50.
Causes of meibomian cyst:
There are sebaceous oil glands that are located within the eyelids of humans near their lashes and these glands are called as meibomian or tarsal glands. These glands generally produce a thin and oily lubricant that prevents the evaporation of the tear film of the human eyes. If the lubricant is not able to flow out of the gland, it will build up and form a bump in the eyelid. As the oily secretions gather, they may leak into the surrounding tissues, thereby causing the eyelid to swell.
Both chalazion and styes are generally complications caused in blepharitis, which is a chronic swelling of the eyelids. The other reasons that cause chalazion are conditions that cause the meibomian gland to secrete and become uncommonly thick and unable to exit the gland like acne rosacea and dysfunction of the gland. Apart from these reasons, people with the following conditions are at the higher risk of getting meibomian cyst:
• Viral infections
Symptoms and complications:
The fundamental symptom of this condition is a painless lump inside the upper eyelid and less commonly, it can develop inside the lower eyelid as well. It can also be accompanied by an increase in tears. In case, it develops to a point of causing swelling, it can lead to redness and painful swelling around the cyst. As it will create pressure on the cornea when it becomes large and present in the middle of the eyelid, it can temporarily cause astigmatism, thereby resulting in blurred vision.
When talking about the complications created by this condition, it can lead to hyperopia and it can easily induce vision problems, particularly in people, who underwent Lasik Surgery. The reason is that this surgery generally is known to thinness and weakness of cornea. The other complications associated with this condition are eyelid disfigurement, pyogenic granuloma and preseptal.
