a disease that causes the conjunctiva to appear white is
A type of severe headache accompanied by various visual symptoms. Pinquecula. An abnormal growth of tissue on the conjunctiva, the clear membrane that covers the white of the eye. Presbyopia. An age-related vision condition in which there is a gradual loss of the eye’s ability to focus on near objects. Pterygium. An abnormal growth of tissue on the conjuctiva, the clear membrane that covers the white of the eye, and the adjacent cornea, the clear front surface of the eye. Ptosis. An inflammation or infection of the conjunctiva, the thin transparent layer of tissue that lines the inner surface of the eyelid and covers the white part of the eye. Convergence Insufficiency. An eye coordination problem in which the eyes have a tendency to drift outward when reading or doing close work. Pink eye (conjunctivitis) is an inflammation or infection of the transparent membrane (conjunctiva) that lines your eyelid and covers the white part of your eyeball. When small blood vessels in the conjunctiva become inflamed, they're more visible. This is what causes the whites of your eyes to appear reddish or pink. Pink eye is commonly caused by a bacterial or viral infection or an allergic reaction. It may affect one or both eyes. Pink eye can be irritating, but it rarely affects your vision. Treatments can help ease the discomfort of pink eye. Other causes include trauma, medications such as steroids, systemic diseases such as diabetes, and prolonged exposure to ultraviolet light. Occasionally, babies are born with a cataract. Cataracts typically develop slowly and progressively, causing a gradual and painless decrease in vision. Conditions that affect the liver’s functioning can lead to yellow eyes. Liver scarring (cirrhosis) commonly causes this to occur. Conditions that can cause cirrhosis include: 1  alcohol abuse. 2  hepatitis, a viral infection of types A, B, C, D, and E. 3  liver cancer. 4  liver infection.

It is important to differentiate whether the engorged blood vessels that cause an eye to appear red are superficial or deep. 2  Red eye due to conjunctivitis is relatively common and does not require emergency treatment. This could be due to gallstones. Gallstones are the most common cause of bile duct obstruction. Other causes include cysts, tumors, or gallbladder inflammation. In addition to yellow eyes, gallbladder obstruction causes symptoms such as: 1  bloody-appearing stool. 2  chills. 3  fever. 4  stomach pain. Certain conditions can cause the eyes and even the skin to appear yellow. Yellowing of the eyes is typically a result of dysfunction of the liver, gallbladder, or pancreas. In some instances yellow eyes can involve multiple organs. Yellowing eyes are a symptom of a condition called jaundice. Finally, not all cases of pink eye are caused by conjunctivitis. Sometimes more serious conditions, such as infections, damage to the cornea, very severe glaucoma, or inflammation inside the eye will cause the conjunctiva to become inflamed and pink. Red eye is a non-specific sign of inflammation or infection. It may be seen with diseases of the external eyelids, third eyelid, conjunctiva, cornea, and sclera. It may also occur with inflammation of the structures inside the eye, with glaucoma (high pressure within the eye) or with certain diseases of the orbit (eye socket). Either one or both eyes can become red, depending upon the cause of the problem. Eyes become reddened when blood vessels of the conjunctiva (the pink lining of the eyeball and eyelids), sclera (white covering of the eye), or cornea (clear surface of the eye) become enlarged or more numerous.
