Small white bumps in the eyes of the elderly may be caused by pterygium or blepharospasm. In the event of damage and stimulation of the eye surface, or long-term exposure to wind, dust and sunlight, the fibers and blood vessels of the local bulbar conjunctiva proliferate and grow into the cornea, which is shaped like a pterygium, or can be manifested as a small white pimple in the eye, which can have a certain impact on the eyesight in severe cases. With age, long-term exposure of the cornea and conjunctiva of the eye surface to air or exposure to ultraviolet light can lead to the appearance of blepharospasm, which is mainly manifested as a yellowish-white plaque without blood vessels, and is generally more likely to occur on the nasal side than on the temporal side. When small white bumps in the eyes of the elderly occur repeatedly or have a serious impact on vision, it is necessary to go to the ophthalmology clinic in a timely manner, slit lamp microscopy and other auxiliary examinations to identify the cause of the disease and then targeted treatment.
