Fatty particles in the inner corner of the eye can be observed without treatment if they are relatively small and do not affect the appearance, but can be surgically removed if the fat particles are large and affect the appearance. The formation of fat particles in the inner corner of the eye is usually caused by yellow tumors or fat deposits in the lacrimal caruncle. Yellow tumors are formed by fat deposits beneath the skin in the inner corner of the eye, while fat deposits in the lacrimal caruncle area are caused by the formation of adipose tissue under the mucous membrane in the lacrimal caruncle area. Both can usually be left untreated and closely monitored for changes when they are relatively small in size, or surgically removed if they are large enough to affect the patient’s appearance. Patients with fat particles in the inner corners of the eyes can go to the ophthalmology department of the hospital for a clear diagnosis and treatment under the guidance of the doctor.
