Fast assessment of acetabular coverage using stereoscopic volume rendering.

Previous CT-based methods of measuring acetabular coverage of the femoral head have either been labor-intensive or have required extensive preprocessing of the data prior to visualization. We propose a method of measuring acetabular coverage using stereoscopic digitally reconstructed radiographs that required very little labor or image preprocessing time. Taking a craniocaudal view of the pelvis, we measured both preoperative and postoperative CTs of 10 patients treated with transtrochanteric periacetabular osteotomy. Measurements were then made in both monocular and stereoscopic rendering modes. Our method is fast, easy, and provides an intuitive means of visualizing an orthopedic parameter that is important in the progression of early hip arthritis.

[Adverse reaction after use of latanoprost in Japanese glaucoma patients].

PURPOSE: Although latanoprost has proven to have a strong hypotensive effect, some patients show adverse reactions such as eyelid pigmentation, iridial pigmentation, or hypertrichosis. We prospectively investigated these adverse reactions. SUBJECTS AND METHODS: One hundred and one Japanese glaucoma or ocular hypertension patients were included. Iridial, eyelid, and eyelash photographs were taken before and at 6 months after latanoprost treatment. Increased eyelid pigmentation, iridial pigmentation, eyelash pigmentation, vellus hair of the lid, and hypertrichosis were assessed from these photographs. The correlation between the incidence of these adverse reactions and the time of instillation, type of glaucoma, sex, age, or concomitantly used eye drops, and the overlap of these were evaluated. RESULTS: Increased pigmentation of the eyelid was found in 6 cases(5.9%), of the iris in 32 cases (31.7%), of the eyelashes in 29 cases (28.7%), vellus hair of the lid in 38 cases(37.6%), and hypertrichosis in 51 cases(50.5%). Pigmentation of the eyelid was more frequently observed in patients who used latanoprost concomitantly (16.7%) than in those who did not use anti-glaucomatous eye drops before latanoprost treatment (1.6%), or in those treated with latanoprost who had switched from other anti-glaucomatous eye drops (6.3%) (p= 0.03). CONCLUSIONS: The incidence of adverse reactions caused by latanoprost was higher in the eyelashes and iris than in the eyelid.

Corneal endothelial cell morphology in patients undergoing cataract surgery.

PURPOSE: To evaluate the effect of age, gender, axial length, and presence of type II diabetes on corneal endothelial cell morphology in patients undergoing cataract surgery. METHODS: The corneal endothelial cell morphology was investigated in 1,819 eyes of 1,394 patients before cataract surgery. The parameters examined include cell density, coefficient of variation of cell area, and percentage of hexagonal cells. The effects of age, gender, axial length, and presence of type II diabetes on these parameters were evaluated. RESULTS: The mean values in endothelial cell density, coefficient of variation of cell area, and percentage of hexagonal cells in all eyes, were 2,543 +/- 254 cells/mm2 (range, 1906-3,252), 0.64 +/- 0.10 (range, 0.34-1.00), and 37.9 +/- 7.1% (range, 17.6-61.7), respectively. Stepwise multiple regression analysis revealed that age was the only explanatory variable to be relevant to corneal endothelial cell density (R = -0.201, p < 0.0001), coefficient of variation of cell area (R = 0.066, p = 0.0046), and percentage of hexagonal cells (R = -0.086, p = 0.0002). The other variables, including gender, axial length, and presence of type II diabetes mellitus, were found to be irrelevant to any of the parameters of corneal endothelial cells. CONCLUSIONS: Age is the major relevant factor in corneal endothelial cell morphology in patients before cataract surgery.
