RESUMEN
PURPOSE: To determine the role of the choroidal vasculature in the pathogenesis of exudative retinal detachments in preeclampsia using indocyanine green angiography. METHODS: We reviewed both fluorescein and indocyanine green angiographic findings for four patients with preeclampsia. RESULTS: Indocyanine green angiographic findings in patients with preeclampsia include nonperfusion in the early phases of the angiogram and staining of the choroidal vasculature with subretinal leakage in the late phases of the angiogram and multiple punctate areas of blocked fluorescence. CONCLUSION: Indocyanine green angiography indicates that damage to the choroidal vasculature leads to many of the retinal changes seen in preeclampsia.

Between July 1963 and December 1974, we surgically treated 207 patients who had severe scoliosis (curves greater than 90 degrees), 196 of whom were eligible for inclusion in this study. No patient was treated preoperatively with a cast or traction. Upon statistical analysis, age and preoperative curve magnitude proved to be significant variables relative to the amount of surgical correction obtained and the maintenance of that correction; sex and etiology of the scoliosis were not shown to affect either surgical outcome or maintenance of correction. A comparative analysis showed our results to be as good as those reported by others using various preoperative regimens of casting or traction or both. Therefore, we find that the preoperative application of traction to patients with severe scoliosis yields no better correction than the use of Harrington instrumentation and fusion alone.
