Ocular Ascariasis: Ocular Ascariasis is an infectious disease caused by the larvae of canine or feline Ascaris lumbricoides invading the tissues of the eye. It is characterized by dark shadows in front of the eyes and loss of vision. It is treated by taking broad-spectrum anthelmintic drugs such as albendazole and mebendazole, which are contraindicated for people with severe liver, kidney and heart insufficiency. 2. Ocular porcine cysticercosis: Ocular porcine cysticercosis is a disease caused by porcine cysticercus parasites in the eye, and the patient is infected after swallowing food mixed with porcine tapeworm eggs or segments. Progressive, painless loss of vision and visual field defects in various areas may occur. It may be relieved by taking broad-spectrum anthelmintics such as praziquantel and thiabendazole, which are contraindicated in patients with ocular cysticercosis. There may also be other parasites in the eye, such as Toxoplasma gondii, etc. If there is a case of parasites in the eye, go to the hospital in time, take medication under the guidance of the doctor, and communicate with the doctor in time for surgical treatment if the medication is not satisfactory.
