 =====Dry eye syndrome===== =====Dry eye syndrome=====
  
-Dry eye syndrome is a condition in which the eyes do not produce enough tears or the tears evaporate too quickly. Tears are necessary to keep the eyes moist, comfortable, and healthy. Without enough tears, the eyes can become dry, itchy, and red, and vision can become blurry.+Dry eye syndrome[(DES)] is a condition in which the eyes do not produce enough tears or the tears evaporate too quickly. Tears are necessary to keep the eyes moist, comfortable, and healthy. Without enough tears, the eyes can become dry, itchy, and red, and vision can become blurry.
  
 There are several causes of dry eye syndrome, including aging, certain medical conditions, medications, and environmental factors such as dry air and wind. Women are more likely to develop dry eye syndrome than men, especially during menopause. There are several causes of dry eye syndrome, including aging, certain medical conditions, medications, and environmental factors such as dry air and wind.

-Conjunctivitis, also known as "pink eye," is an inflammation of the conjunctiva, the clear membrane that covers the white part of the eye and the inner surface of the eyelids.+Conjunctivitis[(Conjunctivitis)], also known as "pink eye," is an inflammation of the conjunctiva, the clear membrane that covers the white part of the eye and the inner surface of the eyelids.
  
 Conjunctivitis can be caused by a number of things, including bacterial or viral infections, allergies, or irritants. The most common symptoms include redness, itching, and discharge in one or both eyes. The discharge can make the eyelashes stick together, especially upon waking up. Bacterial conjunctivitis is usually treated with antibiotic eye drops or ointment, while viral conjunctivitis is usually self-limiting and will resolve on its own within 7-14 days. Allergic conjunctivitis is treated with antihistamine drops or oral medication, and irritant conjunctivitis can be treated by avoiding the irritant and using lubricating drops. Conjunctivitis can be caused by a number of things, including bacterial or viral infections, allergies, or irritants.

 =====Refractive errors (nearsightedness, farsightedness, astigmatism)===== =====Refractive errors (nearsightedness, farsightedness, astigmatism)=====
  
-Refractive errors are common eye conditions that occur when the eye is unable to properly focus light onto the retina. The three most common types of refractive errors are myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.+Refractive errors[(myopia)][(hyperopia)][(Astigmatism)] are common eye conditions that occur when the eye is unable to properly focus light onto the retina. The three most common types of refractive errors are myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
  
 Myopia, or nearsightedness, occurs when the eye is too long or the cornea is too curved, causing light to focus in front of the retina instead of on it. This results in difficulty seeing objects that are far away, but objects that are close can be seen clearly. Myopia, or nearsightedness, occurs when the eye is too long or the cornea is too curved, causing light to focus in front of the retina instead of on it.

 =====Strabismus (crossed eyes)===== =====Strabismus (crossed eyes)=====
  
-Strabismus, also known as "crossed eyes," is a condition in which the eyes are not properly aligned with each other. This can cause one eye to turn in, out, up, or down while the other eye is looking straight ahead. This can lead to double vision, eye strain, and loss of depth perception.+Strabismus[(Strabismus)], also known as "crossed eyes," is a condition in which the eyes are not properly aligned with each other. This can cause one eye to turn in, out, up, or down while the other eye is looking straight ahead. This can lead to double vision, eye strain, and loss of depth perception.
  
 Strabismus can occur at any age and can be caused by a variety of factors, including eye muscle weakness, nerve damage, or a problem with the brain's ability to control eye movement. It can be present at birth or develop later in life. Strabismus can occur at any age and can be caused by a variety of factors, including eye muscle weakness, nerve damage, or a problem with the brain's ability to control eye movement.

 =====Amblyopia (lazy eye)====== =====Amblyopia (lazy eye)======
  
-Amblyopia, also known as "lazy eye," is a condition in which the vision in one eye is weaker than the other. This can occur when the eye and the brain are not working together correctly. This can happen for several reasons such as strabismus (crossed eyes), unequal refractive error (one eye is more nearsighted, farsighted, or has more astigmatism), or obstruction of one eye's visual axis.+Amblyopia[(Amblyopia)], also known as "lazy eye," is a condition in which the vision in one eye is weaker than the other.

 Amblyopia can affect children and adults, but it is most commonly diagnosed in childhood. The weaker eye may appear normal, but the brain is not receiving or suppressing the visual information from that eye, leading to poor vision in that eye. Amblyopia can affect children and adults, but it is most commonly diagnosed in childhood.

 =====Keratoconus====== =====Keratoconus======
  
-Keratoconus is a condition in which the cornea, the clear front part of the eye, becomes thin and irregular in shape. This can cause the cornea to bulge into a cone-like shape, which can cause distorted and blurry vision.+Keratoconus[(Keratoconus)] is a condition in which the cornea, the clear front part of the eye, becomes thin and irregular in shape. This can cause the cornea to bulge into a cone-like shape, which can cause distorted and blurry vision.
  
 Keratoconus usually starts to develop in the teenage years and progresses in the early adult years. The exact cause is not known, but it is thought to be a combination of genetic and environmental factors. Keratoconus usually starts to develop in the teenage years and progresses in the early adult years.

 =====Uveitis====== =====Uveitis======
  
-Uveitis is a group of inflammatory conditions that affect the uvea, the middle layer of the eye, which is composed of the iris, ciliary body, and choroid. When the uvea becomes inflamed, it can cause a variety of symptoms including eye pain, redness, sensitivity to light, and vision loss.+Uveitis[(Uveitis)] is a group of inflammatory conditions that affect the uvea, the middle layer of the eye, which is composed of the iris, ciliary body, and choroid.

 =====Blepharitis====== =====Blepharitis======
  
-Blepharitis is a condition in which the eyelids become inflamed, causing redness, itching, and a burning sensation in the eyes. The condition is caused by a combination of factors, including bacterial infection, clogged oil glands, and skin conditions such as seborrheic dermatitis or eczema. It is more common for people working in hot and dusty environments.+Blepharitis[(Blepharochalasis)] is a condition in which the eyelids become inflamed, causing redness, itching, and a burning sensation in the eyes. The condition is caused by a combination of factors, including bacterial infection, clogged oil glands, and skin conditions such as seborrheic dermatitis or eczema. It is more common for people working in hot and dusty environments.
  
 Symptoms of blepharitis can include red, swollen, or itchy eyelids, a burning or stinging sensation in the eyes, crusting or flaking of the skin on the eyelids, and a gritty or foreign body sensation in the eyes. In some cases, blepharitis can also cause eyelash loss or misdirection and can lead to recurrent styes or chalazion, which are small, painless bumps that develop on the eyelids. Symptoms of blepharitis can include red, swollen, or itchy eyelids, a burning or stinging sensation in the eyes, crusting or flaking of the skin on the eyelids, and a gritty or foreign body sensation in the eyes.

 =====Retinal detachment===== =====Retinal detachment=====
  
-Retinal detachment is a serious eye condition that occurs when the retina, the light-sensitive layer at the back of the eye, becomes separated from its underlying layer of support tissue. This can cause vision loss or blindness if left untreated.+Retinal detachment[(Retinaldetachment)] is a serious eye condition that occurs when the retina, the light-sensitive layer at the back of the eye, becomes separated from its underlying layer of support tissue. This can cause vision loss or blindness if left untreated.
  
 The retina is a thin layer of tissue that lines the back of the eye and converts light into electrical signals that are sent to the brain. Retinal detachment occurs when the retina is pulled away from the back of the eye, usually as a result of a tear or hole in the retina. The retina is a thin layer of tissue that lines the back of the eye and converts light into electrical signals that are sent to the brain.

 =====Optic neuritis===== =====Optic neuritis=====
  
-Optic neuritis is an inflammation of the optic nerve, which is the bundle of nerve fibers that carries visual information from the eye to the brain. Optic neuritis can cause a sudden loss of vision, usually in one eye, and can be a symptom of multiple sclerosis (MS) or other neurological disorders.+Optic neuritis[(neuritis)] is an inflammation of the optic nerve, which is the bundle of nerve fibers that carries visual information from the eye to the brain. Optic neuritis can cause a sudden loss of vision, usually in one eye, and can be a symptom of multiple sclerosis (MS) or other neurological disorders.
  
 The symptoms of optic neuritis can include a sudden or gradual loss of vision, usually in one eye, eye pain, especially with eye movement, and color vision loss. The affected eye may also appear reddish and swollen, and the vision may be blurry or distorted. Loss of vision can range from mild to severe, and in some cases, it can lead to blindness. The symptoms of optic neuritis can include a sudden or gradual loss of vision, usually in one eye, eye pain, especially with eye movement, and color vision loss.
