Why is there a pressure feeling in my right eye?

Because the eyes are an organ exposed to the outside world, they are also very fragile. There are often many problems that arise, which makes patients very worried. It has a great impact on life and work. Some people always feel a sense of pressure in their right eye, and the first thing they think of is that they did not get enough rest. But no matter what, I still need to understand why I feel pressure in my right eye, so that I can feel at ease.

It is considered to be caused by conjunctivitis and high intraocular pressure.

Intraocular pressure is the pressure inside the eyeball, which is referred to as IOP. It can cause headaches, red and swollen eyes, halo vision, which means seeing colored halos when looking at lights, and decreased vision. Severe cases may cause nausea and vomiting.

Posture and food factors

For a normal person, the intraocular pressure may rise by six mmHg when changing from a sitting position to a lying position. If you stand upside down, your intraocular pressure may rise by more than ten millimeters of mercury. Therefore, if glaucoma patients do yoga, we will advise them to avoid inverted movements as much as possible. In addition, drinking a large amount of fluid (such as 500CC) in a short period of time can increase intraocular pressure. Some medicines can also cause the side effect of increased intraocular pressure, the most noteworthy of which are medicines containing steroids. Regardless of the route of administration, whether oral, skin application, nasal spray or eye drops, as long as it contains steroids, there is a chance of this side effect.

Disease factors

Eye diseases such as glaucoma, diabetes, cardiovascular disease, iridocyclitis, cataracts, and myopia can all cause high intraocular pressure, and trauma can also cause high intraocular pressure.

Factors in daily life

Staying in the dark for too long; looking down or reading for too long; not getting enough rest and overworking; overeating; seasonal changes.

Conjunctival congestion and increased secretions are common characteristics of various conjunctivitis. The inflammation can occur in one eye or both eyes simultaneously/sequentially.

Conjunctivitis:

1. Symptoms

The affected eye may experience a foreign body sensation, burning sensation, heavy eyelids, and increased secretions. When the lesion involves the cornea, photophobia, tearing, and varying degrees of vision loss may occur.

2. Physical signs

The signs of conjunctivitis are an important basis for the correct diagnosis of various conjunctivitis.

(1) Conjunctival congestion The characteristic of conjunctival vascular congestion is that the closer to the dome, the more obvious the congestion. The blood vessels are distributed in a reticular manner and are bright red in color. They can extend into the periphery of the cornea to form corneal pannus. The congestion disappears quickly after the application of epinephrine.

(2) Purulent discharge is common in gonococcal conjunctivitis; mucopurulent or catarrhal discharge is common in bacterial or chlamydial conjunctivitis, and often adheres firmly to the eyelashes, making it difficult to open the eyelids in the morning; watery discharge is usually seen in viral conjunctivitis.

(3) Conjunctival edema. Conjunctival inflammation causes conjunctival blood vessel dilation and exudation, leading to tissue edema. Because the bulbar conjunctiva and fornix conjunctiva tissues are loose, they bulge out significantly when edematous.

(4) Subconjunctival hemorrhage is mostly in the form of dots or small patches. Epidemic hemorrhagic conjunctivitis caused by viruses is often accompanied by subconjunctival hemorrhage.

(5) The papilla is a nonspecific sign of conjunctival inflammation and can be located on the palpebral conjunctiva or corneal limbus. It presents as a raised polygonal mosaic appearance with areas of hyperemia separated by pale grooves.

(6) Follicles Follicles are yellow-white, smooth, round protrusions with a diameter of 0.5 to 2.0 mm. However, in some cases, such as chlamydial conjunctivitis, larger follicles may also appear. Viral conjunctivitis and chlamydial conjunctivitis are often accompanied by obvious follicle formation and are called acute follicular conjunctivitis or chronic follicular conjunctivitis.

(7) Membrane and pseudomembrane Membrane is a cellulose exudate attached to the surface of the conjunctiva. Pseudomembrane is easy to peel off, while true membrane is not easy to separate. After forced peeling, the wound will bleed. The essential difference between the two lies in the difference in the degree of inflammatory response. The inflammatory response of true membrane is more severe. Corynebacterium diphtheriae causes severe membranous conjunctivitis; β-hemolytic streptococci, Klebsiella pneumoniae, gonococci, adenovirus, inclusion bodies, etc. can all cause membranous or pseudomembranous conjunctivitis.

(8) Damage to scar matrix tissue is the histological basis of conjunctival scar formation. Early manifestations of conjunctival scarring include narrowing of the conjunctival fornix and subepithelial fibrosis of the conjunctiva.

(9) Swollen preauricular lymph nodes Viral conjunctivitis is often accompanied by swollen preauricular lymph nodes.

(10) Pseudoptosis is caused by hypertrophy of the upper eyelid tissue due to cell infiltration or scar formation, resulting in mild ptosis, which is more common in the late stage of trachoma.

(11) Conjunctival granuloma is less common and can be seen in chronic inflammation caused by tuberculosis, leprosy, syphilis and rickettsia.

Because the eyes are one of the most important organs, we must pay attention to them once a problem occurs. The above article introduces some reasons why there is a feeling of pressure in the right eye. We also know that it may be caused by inflammation. No matter what, I hope that patients with problems can go to the hospital for a check-up so that they can receive timely treatment and ensure their health.
