Conjunctival Biopsy - Assessment of Conjunctival Crystals

Conjunctival crystals may be seen in gout, cystinosis, hypergammaglobulinemias and other conditions.

Formalin is not an appropriate fixative for many types of conjunctival crystals. Urate and cystine should be fixed (and processed) in absolute alcohol (without contact by any aqueous medium). Please contact your pathologist or us for information before taking biopsy samples for conjunctival crystals.
