Acute angle-closure glaucoma occurs when the iris blocks the flow of fluid from the anterior chamber, leading to a rapid increase in intraocular pressure. Dilated pupils, narrow anterior chamber angle, and increased intraocular pressure are all contributing factors.

The immediate goal in treating acute angle-closure glaucoma is to reduce intraocular pressure as quickly as possible to prevent permanent vision loss. This can be achieved through medications, laser therapy, or surgery.

Uveitis is an inflammation of the uvea, the middle layer of the eye. Common symptoms include eye pain, blurred vision, floaters, and redness.

Autoimmune disorders, such as rheumatoid arthritis and ankylosing spondylitis, are the most common cause of uveitis. Infections and trauma can also lead to uveitis, but they are less common causes.

Uveitis can lead to a variety of complications, including cataracts, glaucoma, retinal detachment, and macular edema. Early diagnosis and treatment are essential to prevent these complications.

Corneal abrasions are usually caused by trauma, such as scratches from fingernails, tree branches, or other objects. Infections and chemical burns can also cause corneal abrasions, but they are less common.

The primary goal of treatment for corneal abrasions is to prevent infection, relieve pain, and promote healing. This can be achieved through antibiotics, pain relievers, and lubricating eye drops.

Retinal detachment occurs when the retina separates from the underlying choroid. Common symptoms include flashes of light, floaters, and a curtain-like shadow in the peripheral vision.

Posterior vitreous detachment, lattice degeneration, and retinal tears are all risk factors for retinal detachment. Posterior vitreous detachment is the most common cause, occurring when the vitreous gel separates from the retina.

Retinal detachment can lead to a variety of complications, including macular degeneration, glaucoma, cataracts, and permanent vision loss. Early diagnosis and treatment are essential to prevent these complications.

The primary goal of treatment for retinal detachment is to reattach the retina, prevent further detachment, and restore vision. This can be achieved through surgery, laser therapy, or a combination of both.

Chemical burns to the eye can be caused by acids, bases, solvents, and other corrosive substances. These substances can cause severe damage to the cornea, conjunctiva, and other parts of the eye.

The primary goal of treatment for chemical burns to the eye is to irrigate the eye, neutralize the chemical, prevent infection, and promote healing. This can be achieved through copious irrigation, topical medications, and antibiotics.

Orbital cellulitis is an infection of the tissues surrounding the eye. Common symptoms include eye pain, swelling around the eye, fever, and proptosis (forward displacement of the eye).

Orbital cellulitis can be caused by a variety of factors, including sinusitis, dental infections, trauma, and other infections. Sinusitis is the most common cause, as the infection can spread from the sinuses to the orbit.

Orbital cellulitis can lead to a variety of complications, including meningitis, cavernous sinus thrombosis, optic nerve damage, and permanent vision loss. Early diagnosis and treatment are essential to prevent these complications.
