Stye is a condition that can be diagnosed clinically by a qualified medical professional. The steps usually followed are:
- Symptoms of patient: What the patient feels and complains about help to differentiate between different eyelid diseases like stye, chalazion or blepharitis. (See Section on Similar Conditions)
- Examination of eyes: A complete examination of the area around the eye and conjunctiva (thin membrane inside the eyelid) is done by the medical professional. Careful inspection should be done of the eyelids to distinguish an external and internal hordeolum.
- Other tests: Tests such as Slit lamp and Fundoscopic examination may be required to rule out other pathology of eyelids.
