Abnormal results fall into the following categories: benign fibrous nodule, complex cyst, suspicious lesion, and lesion highly suggestive of cancer. In cases where ultrasound shows the presence of a complex cyst or.
Because diagnostic ultrasound is generally used to investigate symptoms, the results of a scan will often be abnormal and they will detect evidence of an underlying condition.

An orbit is part of the facial bones. They area also called the eye sockets.
The thin bones that make up part of the orbit at the inner angle of the eye are called the lacrimal bones. They are small and delicate, and contribute to the formation of the tear ducts and the medial wall of the orbit.
The Lacrimal gland is located in the lateral part of the orbit.
This will depend upon what exactly you mean by "eye infection". Generally owners consider this to be any inflammatory process occurring in or around the orbit. Inflammation of the conjunctiva (the pink membrane around the inside of the orbit) is one of the more common "eye infections" people will describe. With conjunctivitis, the perimeter of the orbit becomes red and swollen, often partially or completely closing the eyelids. An exudate often accompanies this, resulting in crusty material around the orbit and sometimes sealing the eyelids closed. True eye infections, where the eye itself is experiencing an inflammatory event, will look different. The sclera (white part of the eye) often becomes injected, meaning the blood vessels enlarge and are more prominent, looking something like a red roap map over the white of the eye. The pupil may be dilated or constricted, depending upon the exact location of the infection, and the cornea is often cloudy or red.
A normal ultrasound scan would indicate a fully healthy eye. For therapeutic ultrasound, a normal result would be an improvement in the targeted condition, such as shrinking of a tumor or lessening of pressure inside the eye of a.
Ultrasound imaging equipment allows eye specialists (ophthalmologists) to "see" the eye in great detail without the pain and risk of exploratory surgery, or the limitations and uncertainty inherent to traditional visual examination.
Improperly focused, high-intensity ultrasound could burn and physically disrupt delicate eye tissue and cause injury. This risk is, however, slight and would arise only from improper use, or as a potential side effect of tumor or.
Ultrasound of the eye, properly performed by qualified personnel using appropriate equipment, has no risks. There is no evidence to suggest that the procedure itself poses any threat to a healthy eye, or worsens the condition.

There is no improvement, or the condition worsens 15-35% of the time. A second operation may rectify less-than-perfect outcomes.

Preparation by the patient is generally unnecessary, although under special circumstances an ophthalmologist may perform pretest procedures. The ophthalmologist and/or ultrasound technician will conduct all preparations.
Anatomically, the word 'orbit' means the space within the skull within which the eye sits and moves about.
Another name for the eye is oculus, which is Latin.
Patients may experience partial and temporary blurred vision, as well as "eye strain" headaches. These symptoms usually fade within an hour of the procedure, during which time patients should rest their eyes and avoid all activities.
