Introduction
MRI of the eye can examine the vitreous body, ocular blood vessels, and extraocular muscles. Specifically, as a medical imaging technique, ocular MRI can penetrate superficial tissues to visualize the vitreous body and detect whether there is any vitreous opacity. If opacity is present, the patient may experience decreased vision.
Ocular magnetic resonance imaging (MRI) can examine the vitreous body, ocular blood vessels, extraocular muscles, and other structures. The specific analysis is as follows:
1. Vitreous Body
As a type of medical imaging examination, ocular MRI can penetrate superficial tissues to visualize the vitreous body and detect whether turbidity exists. If turbidity is present, patients may experience decreased vision, in which case vitrectomy at a qualified medical institution may be required.
2. Ocular Blood Vessels
Ocular MRI can also reveal the detailed distribution of ocular blood vessels, identifying any abnormal dilation or rupture, thus providing critical information for diagnosing eye diseases.
3. Extraocular Muscles
The primary function of the extraocular muscles is to control eye movement and eyelid motion. Ocular MRI can detect abnormalities such as muscle tears and assess whether these have impaired normal eye function.
In addition, ocular MRI can evaluate other structures including the sclera, optic nerve, and retina. It is recommended that patients actively cooperate during the examination.
