RESUMEN
To evaluate the color vision of patients with macular diseases after implanting a blue light-filtering intraocular lens (IOL) during vitrectomy. Twenty-seven patients had a blue light-filtering IOL implanted during vitrectomy for macular diseases (macular disease group), and 40 patients without macular disease had the same type of IOL implanted (non-macular disease group). The postoperative best-corrected visual acuity (BCVA) was ≥ 16/20 in all patients. The Farnsworth-Munsell 100-hue test was used to determine total error scores (TES) and mean error scores under photopic and mesopic conditions in both groups. The TES under mesopic conditions was significantly higher than that under photopic conditions in both groups (P < 0.05). However, the TES in the macular disease group was not significantly different from that of the non-macular disease group under both photopic and mesopic conditions. The mean error scores under photopic conditions for hues 11, 14, 16, 17, 18, and 20 (yellowish-red to yellow) were significantly higher in the macular disease group than in the non-macular disease group. The mean error scores for hues 7 and 85 (red) were significantly higher in the non-macular disease group than in the macular disease group. Under mesopic conditions, the mean error scores for hues 30, 60, and 61 were significantly higher in the non-macular disease group than in the macular disease group (P < 0.05). Our results indicate that blue light-filtering IOLs do not alter color discrimination in eyes with macular diseases, and these patients had good postoperative BCVA even under mesopic conditions.

We report a case of simultaneous occurrence of thymic epithelial hyperplasia and Hodgkin's disease. A computed tomographic scan of the chest revealed a tumor in the anterior mediastinum and conspicuous swelling of lymph nodes in the upper and lower mediastinum. The anterior mediastinal tumor was histologically diagnosed as thymic epithelial hyperplasia, while the lymph nodes were nodular sclerosis Hodgkin's disease. Our findings suggest that thymic hyperplasia might be directly involved in the pathology of at least some cases of Hodgkin's disease.
