An anterior cruciate ligament injury occurs when the anterior cruciate ligament (ACL) is either stretched, partially torn, or completely torn. [1] The most common injury is a complete tear. [ 1 ] Symptoms include pain, an audible cracking sound during injury, instability of the knee, and joint swelling . [ 1 ]
Additionally, certain symptoms, including elevated swelling, paleness, narrower arteries, and hemorrhages, were more common in NAION than in optic neuritis. [ 49 ] The natural progression of NAION following acute vision loss typically includes an improvement in visual acuity by 3 or more lines on the Early Treatment Diabetic Retinopathy Study ...
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
Involutional stenosis is probably the most common cause of nasolacrimal duct obstruction in older people. It affects women twice as frequently as men. Although the inciting event in this process is unknown, clinicopathologic study suggests that compression of the lumen of the nasolacrimal duct is caused by inflammatory infiltrates and edema.
NAION is the most common cause of sudden optic nerve-related vision loss, affecting more than 10,000 Americans every year, often bilaterally. No clinically effective treatments exist, largely because little is known about its pathophysiology, and there are few histopathological studies of the acute condition.
Treatment for ACL injuries typically involves a combination of rehabilitation and surgery, depending on the severity of the tear. Recovery can take anywhere from several months to over a year.
The most common cause of dry eye is increased evaporation of the tear film, typically as a result of meibomian gland dysfunction (MGD). The meibomian glands are two sets of oil glands that line the upper and lower eyelids and secrete the oily outer layer of the tear film—the lipid layer.
Eye injuries, most often occurring in people under 30, are the leading cause of monocular blindness (vision loss in one eye) throughout the United States. Injuries and cataracts affect the eye itself, while abnormalities such as optic nerve hypoplasia affect the nerve bundle that sends signals from the eye to the back of the brain, which can ...
