A small bump has developed on the upper eyelid.

Under normal circumstances, a small bump on the upper eyelid may be related to factors such as milia, conjunctival concretions, hordeolum (stye), folliculitis, or blepharitis. It is recommended that patients receive symptomatic treatment under medical guidance. Specific analyses are as follows:

1. Milia

The skin around the eyes is relatively thin and contains numerous sebaceous glands. When oily skincare products are applied, or when glandular secretions are excessive, accumulated oils may form small bumps on the upper eyelid. It is recommended to visit a reputable hospital where a qualified physician can use a sterile needle to puncture the surface of the milia and extract its contents, thereby improving symptoms.

2. Conjunctival Concretions

If metabolic waste in the conjunctival tissue fails to be properly eliminated, it may accumulate in the eye area, forming small white particles. Patients may use medications such as chloramphenicol eye drops or levofloxacin eye drops under a doctor's supervision.

3. Hordeolum (Stye)

If a bump appears on the upper eyelid accompanied by redness, swelling, heat, and pain, it is likely due to hordeolum. Under medical guidance, patients may use medications such as tobramycin eye drops or levofloxacin eye drops for treatment.

4. Folliculitis

When hair follicles around the eyes are irritated by sweat or infected by pathogens, one or more small bumps may develop centered around the follicles. It is advisable to use topical medications such as mupirocin ointment or erythromycin ointment under a doctor’s direction.

5. Blepharitis

Rubbing the eyes with dirty hands or poor hygiene around the eye area can lead to staphylococcal infection of the inner eyelid. Inflammatory stimulation may then cause small bumps on the eyelid. Under medical advice, using erythromycin eye ointment or levofloxacin eye drops can help control the infection and improve symptoms.

In addition, other possible causes include dyshidrotic eczema or chalazion. If patients experience any discomfort, they should seek timely medical evaluation at a hospital to avoid delays in diagnosis and treatment.
