Acanthamoeba eye infections in contact lens wearers are rare but serious, and they often start because of improper lens handling and poor hygiene. Amblyopia also known as lazy eye, affects just two to three percent of the population. But, if left uncorrected, this vision problem can have a very big impact on those affected. Central vision fails to develop properly, usually in one eye, which is called amblyopic. A related condition, strabismus, sometimes causes amblyopia. Bell's palsy is a temporary weakness or paralysis of the facial nerve known as the seventh cranial nerve. This nerve controls facial expressions, eyelid movement and the muscles of the forehead and neck. Blepharitis is a common eyelid inflammation that is sometimes associated with a bacterial eye infection, symptoms of dry eyes or certain types of skin conditions such as acne rosacea. Blepharitis has two basic forms:
Anterior blepharitis, affecting the outside front of the eyelid where eyelashes are attached. Posterior blepharitis, linked to dysfunction of meibomian glands found in the inner eyelid where oily secretions are released to help lubricate the eye. A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil. The lens works much like a camera lens, focusing light onto the retina at the back of the eye. The lens also adjusts the eye's focus, letting us see things clearly both up close and far away. The lens is mostly made of water and protein. The protein is arranged in a precise way that keeps the lens clear and lets light pass through it. Eye Diseases
Cytomegalovirus (CMV) retinitis is a sight-threatening disease frequently associated with Acquired Immunodeficiency Syndrome (AIDS). In the past, about a quarter of active AIDS patients developed CMV retinitis. A pink eye is the most obvious symptom of conjunctivitis, so the term "pink eye" often is used for this common...
