Purpose: To evaluate a limbal stem cell deficiency (LSCD) diagnosis method based on the detection of the MUC5AC transcript by reverse transcription-polymerase chain reaction (RT-PCR) in comparison with the standard diagnostic method based on goblet cell detection by periodic acid-Schiff (PAS)-hematoxylin staining, using samples obtained from corneal epithelium impression cytology (IC). Design: Transversal, comparative case series. Participants: We studied 59 eyes from 43 patients clinically diagnosed with LSCD. Methods: Impression cytology was used to gather cells from corneal and conjunctival epithelium from the same eye. The presence of goblet cells in the cornea was determined by PAS-hematoxylin staining, whereas the presence of the MUC5AC transcript was detected by RT-PCR using a custom-designed primer pair. Main Outcome Measures: Goblet cells in the corneal epithelium were detected by light microscopy, and the MUC5AC transcript was detected as the corresponding PCR amplicon in agarose gels. Results: Our study included 59 corneal samples, together with their respective conjunctival samples for RT-PCR assays. Of these, 47 samples were also available for comparative PAS-hematoxylin staining. The MUC5AC amplicon was detected in 56 of 59 (94.9%) corneal epithelium samples. In contrast, conventional IC staining detected goblet cells in only 17 of
