Overview
Goiter
Goiter is an enlargement of the thyroid gland, which is located at the front of the neck and produces hormones that regulate metabolism. A goiter may involve the entire thyroid gland or may occur with one or more thyroid nodules. Some people have no symptoms other than visible or palpable enlargement of the neck. A large goiter can sometimes press on the windpipe or esophagus and cause breathing, coughing, hoarseness, or swallowing problems.
Cataract
A cataract is a clouding of the normally clear lens inside the eye. As the lens becomes cloudy, less light reaches the retina and vision may become blurred, dim, or less sharp. Cataracts usually develop gradually and are most common with increasing age, although they can also occur after eye injury, surgery, certain diseases, or prolonged exposure to factors that damage the lens. Cataracts may affect one or both eyes but do not spread from one eye to the other.

Diagnosis
Goiter
Evaluation of a goiter begins with examination of the neck and thyroid gland. Blood tests can measure thyroid-stimulating hormone and thyroid hormones such as free T4. Thyroid ultrasound can identify enlargement and examine nodules or other structural changes. A thyroid scan and radioactive iodine uptake study may be used in selected cases to assess thyroid function. If a nodule has suspicious features, a biopsy may be recommended to determine whether cancer is present.
Cataract
Cataracts are diagnosed through an eye examination and assessment of vision. An eye care professional may test visual acuity and examine the lens and other structures of the eye using a slit lamp or other instruments. The pupils may be dilated so that the back of the eye can be examined and other causes of vision loss can be assessed. Additional tests may be used when another eye condition is suspected or when surgery is being planned.
Prevention
Goiter
Adequate iodine intake can prevent many cases of simple goiter caused by iodine deficiency. Using iodized salt appropriately is an established way to maintain adequate iodine intake in populations where deficiency is a concern. Other causes, such as autoimmune thyroid disease or genetic susceptibility, cannot always be prevented. Avoiding unnecessary exposure to factors that affect thyroid function and obtaining medical evaluation for persistent neck swelling can help identify thyroid disorders early.
Cataract
Not all cataracts can be prevented, especially those related to aging. Measures that may help reduce risk include protecting the eyes from ultraviolet light with appropriate sunglasses and a wide-brimmed hat, avoiding smoking, protecting the eyes from injury, and controlling medical conditions such as diabetes. A healthy diet containing fruits, vegetables, leafy greens, nuts, and whole grains may support overall eye health. Regular eye examinations can help detect cataracts and other causes of vision changes.
Risk Factors
Goiter
Risk factors vary according to the underlying cause. Being over age 40, having a family history of goiter, and living or having grown up in an area where iodine deficiency occurs can increase risk of some types. Women are more frequently affected by simple goiter. Autoimmune thyroid disease, certain medicines, smoking, and conditions that cause thyroid nodules or abnormal thyroid hormone production can also increase the likelihood of thyroid enlargement.
Cataract
Older age is the most important risk factor for cataracts. Other factors include diabetes, a family history of cataracts, previous eye injury or eye surgery, long-term use of corticosteroids or certain other medicines, smoking, radiation exposure, and prolonged ultraviolet light exposure. Some inflammatory eye diseases and other medical conditions can also increase risk. Risk generally increases as the lens is exposed to these factors over time.
