Sarcoid uveitis is the major complaint of ocular sarcoidosis. The detection of epithelioid granuloma (EG) requires histological biopsy of the uvea for the precise diagnosis of sarcoid uveitis, because it is challenging to diagnose sarcoid uveitis without a history of systemic sarcoidosis. To diagnose sarcoid uveitis, we have established novel methods.Patients and Methods: In this study, we included 30 eyes of 21 patients with granulomatous uveitis diagnosed via slit-lamp examinations, gonioscopy, fundus photography, and fluorescein angiography. Vitrectomy was performed to remove the vitreous opacity with vision loss. To examine vitreous cell components, we used liquid-based cytology (LBC). To detect EG in an intraocular irrigating solution, we collected vitreous cell components, and then the cell pellets were embedded in the cell block procedure.Results: Here, we demonstrated the usefulness of the histological detection of EG and epithelioid cells (ECs) in LBC from vitreous body specimens and in the cell block procedure from vitreous cell components in an intraocular irrigating solution. Our results showed that the detection rates of EG were 6.3% (1/16) in LBC and 9.1% (1/11) in the cell block procedure in the sarcoid uveitis-suspected group and 7.7% (1/13) in LBC and 28.6% (2/7) in the cell block procedure in the sarcoidosis group. We would discuss the specificity of the EG/EC detection of ocular sarcoidosis.Conclusion: Our methods are helpful in the precise diagnosis of ocular sarcoidosis and the control of the development of systemic sarcoidosis.Keywords: uveitis, sarcoidosis, vitrectomy, liquid-based cytology, cell block procedure |
