Before the removal of foreign body, all eyes with slit lamp microscope showed no significant ocular surface damage.Ultrasound slit lamp  microscope combined with fluorescein staining found that ocular surface occult foreign body There were characteristic changes, including "fluorescein staining" and "fluorescein edge set", in which the percentage of "fluorescein staining" was 44.4% and the percentage of "fluorescein" was 92.6% 4 cases with microscopic tweezers out, the remaining 8 cases using a combination of foreign body removal method.After the removal of foreign body, the slit lamp microscope combined with fluorescein staining results showed that 4 eyes showed no significant staining, 2 eyes Coloring flake, 21 eye-like or linear coloring.

All patients were See eye infections caused by foreign matter. Conclusion by finding characteristic changes, slit lamp microscope and corneal fluorescein staining test for the diagnosis and treatment of ocular surface helps occult foreign bodies.
