RESUMEN
PURPOSE: To identify the predictive factors for anatomical and visual outcomes in posterior segment intraocular foreign body (IOFB) patients managed by pars plana vitrectomy (PPV). METHODS: A retrospective chart review was performed for 77 patients, who had PPV for IOFBs removal between January 2001 and July 2007. Univariate and multivariate analyses were conducted to evaluate the predictive factors. RESULTS: The mean age of the patients was 33.4 years. The nature of IOFBs was mainly metal, with injuries most commonly caused by an electric grass trimmer. The mean time interval between injury and IOFBs removal was 30.7 days. The mean preoperative visual acuity (VA) was 1.82 logarithm of the minimal angle of resolution (logMAR), and mean final was VA 1.10 logMAR. From multivariate analysis, good visual outcome was correlated with the corneoscleral entry site, and poor visual outcome was correlated with the presence of relative afferent pupillary defect. CONCLUSIONS: In noncombat IOFBs, most cases were work-related. Delayed IOFBs removal was acceptable when primary wounds were repaired appropriately and extensive antibiotics administered. Even though advancement in vitreoretinal surgery can reduce the frequency of blindness, further promotion and education on eye protection during work are needed.

PURPOSE: To determine the prevalence of pulmonary sarcoidosis in patients with uveitis from the University Referral Centre in Thailand and to report on their clinical characteristics. METHODS: We performed a retrospective review of results of radiological examinations of 209 consecutive new patients, diagnosed with uveitis. In patients with signs of pulmonary sarcoidosis, we reviewed clinical characteristics including age, gender, laterality and anatomical location of uveitis, and complications. RESULTS: From 209 chest X-ray (CXR) examinations, one patient exhibited radiological signs typical of stage 1 sarcoidosis. Chest CT of three patients with posterior multifocal chorioretinitis (PMC) revealed abnormalities suggesting the diagnosis of pulmonary sarcoidosis. All PMC patients were females older than 50 years; they had no pulmonary complaints and their CXRs were without abnormalities. CONCLUSION: Ocular sarcoidosis is prevalent in Thailand and our findings suggest that possibly more patients with sarcoidosis would be identified if diagnosis was thought of and ancillary tests were performed.
