Overview
Laboratory tests are not often required in patients with Blepharitis. In general, blepharitis is diagnosed based on typical patient history, skin and eye examination, and characteristic slit-lamp biomicroscopic findings. However, cultures of the eyelid margins and eyelid biopsy may be indicated for patients who have recurrent anterior blepharitis with severe inflammation, as well as for patients who are not responding to therapy.[1][2]
Laboratory Findings
In general, blepharitis is diagnosed based on clinical features alone. Laboratory studies for blepharitis should include the following:[1][2][3][4][5]
- Cultures of the eyelid margins may be indicated for patients who have recurrent anterior blepharitis with severe inflammation, as well as for patients who are not responding to therapy.
- A biopsy of the eyelid may be indicated to exclude the possibility of carcinoma in cases of marked asymmetry, resistance to therapy, or unifocal recurrent chalazia that do not respond well to therapy.
- Microscopic evaluation of eyelashes may reveal Demodex mites (indicated for patients who have chronic blepharoconjunctivitis)
