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.
