Context:
Frozen sections for ophthalmic tissues require very precise indications.
Objective:
To describe indications and procedures for frozen sections in ophthalmic pathology based on review of my experience and reports in the literature.
Design:
Frozen sections received by the ophthalmic pathology service at The Methodist Hospital from 1996 to 2004 were reviewed. A review of the literature also was performed.
Results:
Of the 277 specimens received, most were eyelid lesions (138, 49.8%), followed by orbital (106, 38.3%), temporal artery (17, 6.1%), optic nerve (9, 3.2%), and conjunctival (7, 2.5%) lesions. A review of appropriate indications for intraoperative diagnosis is presented and a description of tissue handling and procedures to obtain better results in ophthalmic pathologic lesion cases is discussed.
Conclusions:
The most frequent indications for frozen sections in ophthalmic abnormalities are for margin control in eyelid and orbital lesions. At my institution, the second most frequent indications for ophthalmic frozen sections are the evaluation of adequacy of tissue sampling and triaging for flow cytometry and molecular techniques, especially in childhood malignancies.
