Eye pain laboratory tests

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

There are only few tests which help in prognosis of eye pain.

• Routine blood tests are done to evaluate systemic infection
• Rise in white blood cell count
• Rise in CRP signify systemic infection
• Evaluation of diabetes may be useful if immunosuppression is suspected
• Detection of thyroid disease may be useful if proptosis is suspected
• If any discharge is noticed that can be gram stained and cultured
• Intraocular fluids are cultured for cases of endophthalmitis
• Viral cultures can be used to confirm herpes zoster or herpes simplex if the diagnosis is not clear clinically.
