Perimetric probability maps to separate change caused by glaucoma from that caused by cataract.

We describe a new method for analysis of change in glaucomatous visual fields with the object to differentiate between changes caused by glaucoma from those caused by cataract. New pattern deviation change probability maps were developed from a prospectively collected glaucoma material and designed to be sensitive to changes in localized field loss, but to be unaffected by media-induced perimetric change. We compared the new change probability maps with the commercially available total deviation change probability maps in series of Humphrey perimetric tests in a glaucoma material of 43 eyes of 35 patients, who had undergone cataract surgery. When using the total deviation maps, considerable differences were seen between fields obtained before and after cataract surgery. Much smaller differences were seen when using the new change probability maps, that almost eliminated the common and disturbing effect of increasing cataract. This new tool could be of considerable help in differentiation between progressive glaucomatous visual field loss and deterioration caused by increasing media opacities.

Laparoscopy in the diagnosis of primary carcinoma of the gallbladder. A study of 98 cases.

Ninety-eight cases of carcinoma of the gallbladder were studied by laparoscopy from 1968 to 1982. The gallbladder was completely explored in 48 patients. Hard white plaques of the gallbladder wall were noted in 30 patients. Local metastases were found in 89 patients. A diagnosis of malignancy by biopsy was made in 90% of cases although only three biopsies were taken from the gallbladder itself. Laparoscopy is useful in identifying those rare cases where radical surgical intervention may improve survival.

Laparoscopic splenic biopsy.

The authors report their experiences with 1243 laparoscopic splenic biopsies performed between 1968 and 1982 at the Laparoscopy Center of the Regional Hospital in Padua. We may conclude that: The risk of laparoscopic splenic biopsy in minimal and fears regarding its performance are unjustified. The diagnostic value of splenic biopsy is evident if a comparison is made, in the different groups, between the percentage and the accuracy of the diagnoses made with the single macroscopic and the histological examinations, respectively. As well as the staging and follow-up of malignant lymphomas, examination of the spleen in clinically suspected splenopathy is a new and interesting indication for laparoscopy, for it is now possible to take one or more biopsies.
