Purpureocillium lilacinum is an emerging pathogen that can cause severe ocular infections. This study aimed to investigate the risk factors, clinical manifestations, antifungal susceptibilities, and outcomes of ocular infections caused by P. lilacinum at a large ophthalmic center in Southern China. This retrospective study reviewed the medical records of 34 patients with culture-proven P. lilacinum oculomycosis treated at the Zhongshan Ophthalmic Center from January 2020 to December 2024. The study included 34 patients (17 males, 17 females). The most common risk factor was ocular trauma (38.2%). In vitro susceptibility testing revealed high resistance to fluconazole and caspofungin, but general susceptibility to voriconazole (median MIC 0.25 mg/L). Despite 97.1% of patients receiving voriconazole therapy, outcomes were generally poor, with 54.5% of patients experiencing a poor outcome (vision worse than counting fingers). A significantly shorter time to microbiological diagnosis was associated with a favorable outcome (median 26 days vs. 65 days, p = 0.007). In conclusion, the visual outcomes of this infection remain generally poor, with the major clinical challenge being the delay in diagnosis. Therefore, prompt microbiological investigation is recommended for patients with suspected intraocular infection. Voriconazole remains the first-line therapeutic choice, the therapeutic potential of newer triazoles warrants further investigation. Full article
