What Could Be the Cause of a Small White Spot Appearing on My Eye?
The appearance of a small white spot on the eye is a common phenomenon. In such cases, there is no need for excessive worry or blind treatment. Specific judgments should be made based on the location of the white spot. If the white spot appears on the surface of the conjunctiva, it may be a pinguecula, which is often caused by wind and sun exposure. If the white spot appears on the eyeball, it may be a pterygium. What exactly causes a small white spot on the eye? Let's take a look below.
If a small white spot appears on the eyelid and there are no obvious abnormalities in the surrounding skin of the eye, and the white spot is needle-like in size, it is initially considered to be a fat granule. Most patients may have this condition due to blockage of hair follicle secretions, and no treatment is required for the time being. However, some patients may gradually increase in size, and if it affects their appearance, they can consider removing it. If there is local redness and swelling on the eyelid skin, and there is a palpable hard nodule with obvious tenderness when touched, it is usually considered to be an external hordeolum. If the abscess has become mature, it is recommended to incision and drainage. If there are small white spots on the edge of the eyelid, accompanied by symptoms such as a foreign body sensation, it may be caused by blockage of the meibomian glands. Some patients may also experience dryness and soreness. It is recommended to observe first, and some patients may improve spontaneously or choose to puncture with a sterilized needle.
The appearance of a small white spot on the eyeball should generally be judged based on the shape and location of the white spot. If the white spot is located at the inner canthus of the eyeball, it is generally considered to be the early stage of a pterygium. If there is no discomfort, no treatment is required. If the white spot is located above or below the eyeball or beside the iris, it is more likely to be a cyst of the eyeball, which usually requires surgical removal. Additionally, if the white spot is located at the incision site after eye surgery, it is more likely to be a postoperative conjunctival scar reaction. If there is no discomfort, no treatment is required. Furthermore, the white spot can also be considered as an inflammatory reaction of the sclera, which is often accompanied by eye congestion. For specific details, it is recommended to undergo a detailed examination under an ophthalmoscope.
