Workup
Laboratory Studies
- Depending on presentation, obtain specimens (eg, swab, vitreous wick, aqueous) from the external and internal eye for the following studies:
- Gram stain/Giemsa stain
- Cultures and sensitivities
- Calcofluor white (suspected fungal infection)
Other Tests
- Seidel test
- A strip of fluorescein is placed on the area that is suspected for leaks, then the dye color is observed in white light. If a leak is present, the dye will change from orange (concentrated) to green (diluted) and exhibit a waterfall-like effect at the leaking zone.
- The egress of fluid is noted best under blue light.
Procedures
- The vitreous wick may appear like a mucoid substance under slit lamp biomicroscopy. The wick may be teased with a cotton applicator or a cellulose sponge while taking note of synchronous movement of the iris or of the vitreous strand in the anterior chamber.
- A peaked pupil also may indicate a vitreous strand in the anterior chamber.
