Blepharitis is a chronic condition of the eyelid in which they are inflamed and become scaly. This happens when the pores in the eyelids that secrete oil get blocked, or there is excessive secretion of oil through these glands. Dryness in the eyes can also be one of the causes of blepharitis. There are two types of blepharitis depending upon the location they occur in the eyes, anterior and posterior blepharitis. Anterior blepharitis occurs on the outer side of the eyelids while the posterior type of blepharitis occurs where the meibomian glands are present. The latter is mostly seen among people with rosacea type of skin condition, as there is abnormal oil secretion in these people from meibomian oil glands. There are several home remedies and medicinal treatments for blepharitis, but in chronic blepharitis when there are changes in the eyelashes, eye conditions, etc. then blepharitis surgery need to be done.
The first thing that comes into notice is the crusted debris in the eyelashes and at the corners of the eyelids. This is mainly noticed when you wake up early in the morning, your lids may get glued up and then it becomes difficult for your to open eyes. Thereafter, you will notice reddened, swollen, irritated eyelids. Inflammation and dryness in the eyes is also observed and there is sensitivity to light as well. In severe cases, lumps and abnormal growth of the eyelashes is also observed. Eyelashes may also fall down.
Ophthalmologist looks for the above symptoms examining the eyes. He uses magnifying devices so that he can identify the cause and severity of blepharitis. Sometimes certain allergic skin conditions such as eczema, lice infestation, bacterial infection and seborrheic dermatitis can cause blepharitis.
Laboratory tests may also be conducted to diagnose blepharitis. In laboratory tests, a sample of the debris from the eyelids is used to test in the laboratory. This sample is then tested for any bacteria or some other infections.
Some of the simple treatments at home and some over the counter medications can treat blepharitis: it rarely requires any severe surgical treatments. A surgical treatment is mostly opted if there are any changes in the eyelashes and condition of the eyes. Cleaning eyelids regularly for removing the debris on them, and opening the pores of the glands will help you. Regular cleaning is very essential in this case, or else this condition may occur repeatedly. This may require surgery.
Blepharitis can cause conditions such as chalazion and trichiasis. Chalazion is the small bump caused in the eyelids due to blockage of the meibomian glands. These glands are responsible for secreting oil and lubricating eyes. If a bump occurs in these glands, they get blocked and this interfaces secretion of lubricating oil. This condition can cause abnormal growth of eyelashes and dryness in the eyes.
In trichiasis, the eyelashes, instead of growing outwards grow inwards. You will have a poking sensation in your eyes due to this. This also causes pain and irritation. Surgical treatments carried out in this case are as given below.
Epilation: Epilation is the process of epilating or plucking the eyelashes. Special type of forceps is used to do this, and this process can be quiet painful but is inexpensive. The eyelashes, which have been plucked out, will grow back in three to five months. If the newly grown eyelashes are again awkwardly penetrating your eyes then you may need some other treatments.
Electrolysis: Electrolysis is the method of using a proper voltage electric current to destroy the hair follicles permanently. There is very less chance of the growth of the eyelashes in the same manner, only about 40% to 50% of the patients will experience such problem again.
Radio frequency: Radio frequency can also be used in destroying the hair follicles that are growing towards eyes due to blepharitis. It also prevents regrowth of the hair follicles.
Eyelid surgery: The doctor, to remove the chalazion and eliminating the conditions that is causing trichiasis may also perform an eyelid surgery.
The above blepharitis surgery and other treatments will help you in getting rid of this sticky, irritating and chronic condition.
