Final answer:
Chronic lipogranulomatous inflammation of the eyelid caused by the blockage of the meibomian gland is referred to as blepharitis, which can lead to redness, irritation, and in severe cases, vision impairment.
Step-by-step explanation:
The chronic lipogranulomatous inflammation of the eyelid caused by the blockage of the meibomian gland is known as blepharitis. Blepharitis can lead to swelling, itching, and irritation of the eyelids, and if left untreated, can contribute to more serious ocular conditions. When the meibomian gland is blocked, it can result in the growth of bacteria, leading to inflammation that is typically chronic. Although this condition mainly involves the eyelid itself, complications can extend to the conjunctiva and cornea, creating the potential for keratoconjunctivitis or conjunctivitis.Infections leading to blepharitis may have various causes including bacteria, viruses, allergens, or exposure to chemicals and pollutants. Depending on the cause and severity, symptoms may range from redness and irritation to more severe outcomes like corneal scarring, which, without proper medical intervention, can escalate to vision impairment or even blindness.
