A small white grain of rice growing on the inside of the eye may be a case of conjunctivitis, conjunctival stone or chalazion. 1. Conjunctivitis: Conjunctivitis caused by infection or immune factors can cause dilatation of conjunctival blood vessels, increased exudate and cellular infiltration, which leads to the formation of papillary hyperplasia or follicles of the eyelid conjunctiva, which looks like white grains of rice in the inner side of the eye, and is usually accompanied by redness of the eye and increased secretion, and other clinical manifestations of conjunctivitis. 2. Conjunctival stones: Conjunctival stones occurring on the inner side of the eyelid can also appear as a white grain of rice growing on the inner side of the eye, and there may be no obvious symptoms when the stones are small. 3. Chalazion: Blepharophalangeal cysts, caused by the secretions of the blepharophalangeal glands accumulating at the root of the eyelashes or protruding from the inner eyelid due to blockage of the opening of the blepharophalangeal glands, can also have the above manifestations. In order to clarify the specific cause of the growth of a small white grain of rice on the inner side of the eye, it is recommended to go to the ophthalmology department to improve the slit lamp microscope and other auxiliary examination, combined with the relevant medical history to make a judgment, and under the guidance of the doctor targeted treatment.
