RESUMO
PURPOSE: To determine etiological factors in the development of, as well as anatomic success rate and visual outcome of a large consecutive series of macular hole surgeries. METHODS: Retrospective analysis of 300 consecutive cases of macular hole surgery by a single surgeon (RDB) between 1999 and 2003. Patients' medical and surgical histories were recorded and analysed for factors involved in aetiology and visual outcome. RESULTS: There were 8 (4.12%) women, on tamoxifen in the study, two of these women had bilateral macular holes. When this study prevalence of tamoxifen therapy (4.12%) was compared to the estimated percentage of women in the same age group in the Australian population on tamoxifen (0.82%), a statistically significant difference (p value 0.0001) was found. Analysis of the number of bilateral holes in the tamoxifen group compared to the non-tamoxifen group was suggestive of an increased incidence of bilateral holes but not to a significantly significant degree. CONCLUSION: Whilst no published reports link tamoxifen and macular holes, this may be due to the low incidence of the condition. Our study demonstrates a strong link between tamoxifen use and macular holes. Patients being commenced on tamoxifen should be advised of possible ocular complications and receive prompt ophthalmic review if symptoms develop.
