Abstract
PURPOSE: To assess the effect of cataract on the glaucomatous visual field. METHODS: We prospective y assessed the visual field indices of mean deviation (MD), pattern standard deviation (PSD), short-term fluctuation (SF) and corrected pattern standard deviation (CPSD) before and after cataract extraction with posterior chamber intra-ocular lens in a consecutive series of 40 patients (51 eyes) age 75.0 +/- 6.0 years with varying degrees of field oss or suspect field loss. RESULTS: After cataract operation, statistical analysis showed a very significant fall in the absolute magnitude of MD and a significant rise n PSD. There was considerable individual variation in results. CONCLUSION: Taking these changes into account, the indices gave a good prediction of the glaucomatous field status following cataract operation, which itself results in some increase in the underlying field defect.
