Effects of phacoemulsification time on the corneal endothelium using phacofracture and phaco chop techniques.
PURPOSE: To quantitatively assess early postoperative endothelial damage caused by two phacoemulsification techniques and to ascertain the effect of differences in phacoemulsification time. SETTING: Department of Ophthalmology, Umberto Hospital, Lugo, Italy. METHODS: This prospective study evaluated 100 patients who had phacoemulsification using one of two techniques: phaco chop (n = 50) or four-quadrant, divide and conquer phacofracture (n = 50). The endothelium of both groups was analyzed preoperatively and 8 weeks postoperatively by specular microscopy. RESULTS: Phaco chop led to significantly shorter phacoemulsification time and less endothelial damage. Mean equivalent phacoemulsification time was 25.53 seconds +/- 11.26 (SD) in the phaco chop group and 87.26 +/- 48.03 seconds in the phacofracture group. Endothelial cell loss was 4.72 +/- 1.2% and 13.80 +/- 4.3%, respectively. CONCLUSION: The phaco chop technique led to shorter phacoemulsification time and less endothelial cell loss.

Orbital cavernous angiomas: surgical experience on a series of 13 cases.
Cavernous angiomas of the orbit are benign vascular growths, commonly occurring in adults and usually causing a slowly progressive proptosis from their mass effect. These lesions have behavioural and radiological findings different from those of brain cavernous angiomas, probably due to their particular origin and structure. The authors present a surgical series of 13 patients with orbital cavernous angiomas. Complete excision of lesions, with histological diagnosis, was obtained in all the 13 cases. Results were good in 10 patients, while 2 remained clinically unchanged and another one showed acute visual deterioration after a period of postoperative clinical stabilization. The main clinical and radiological characteristics of orbital cavernous angiomas are analyzed, together with their surgical management.

Intracranial and orbital cavernous angiomas: a review of 74 surgical cases.
We present a surgical series of 74 patients (30 males and 44 females) with pathologically verified cavernous angiomas of the intracranial and orbital compartments. Patients were admitted between 1975 and 1991; six had a family history of cerebral cavernomas, and two had multiple (two) lesions. The 76 malformations were located as follows: 57 were in the cerebral hemispheres, four in the supratentorial ventricles, one was in the middle cranial fossa, two were in the brain stem, five in the cerebellum and seven in the orbits. Seizures and focal neurological deficits, and decrease of visual acuity with exophthalmus, were the main clinical signs observed in patients with intracranial and orbital cavernomas, respectively. Sixteen patients (21.6%) had a clinically significant haemorrhage attributable to the cavernous angioma. A number of these vascular malformations were misdiagnosed by computed tomography. In the last 10 years magnetic resonance imaging has been the most sensitive method for detecting these lesions. Seventy-four of the 76 diagnosed cavernomas were treated surgically: a complete excision was obtained in 68 patients; in two patients with multiple lesions only those causing symptoms were removed. Surgery for the 10 deep lesions was aided considerably by stereotactic localization. Two patients died in the immediate postoperative course. The overall outcome was good in 66 of the 72 remaining patients, resulting in improved seizure control or lessened neurological deficit.
