“…In another study 29.4% of patients who had underwent a cataract operation developed cells/mm2, respectively. The endothelial cell loss found in our two cases is higher than the cell loss of 4-25 % reported after intracapsular cataract extraction (Drews & Waltman 1978;Olsen 1980b) and is closer to the values seen after intraocular lens implantation (Bourne et al 1981), but still far from the decompensation limit which may lie somewhere around 300 cells/mm2 (Waring et al 1982).…”

We studied the corneal endothelial cells in 14 patients (6 men and 8 women, ranging in age from 15 to 70 years) with unilateral Fuchs' heterochromic cyclitis (FHC) by means of specular microscopy. The healthy fellow eyes of the patients served as control material. Two affected eyes had undergone an intracapsular cataract extraction before specular microscopy. In one patient, the cyclitic eye also had glaucoma. Changes of the endothelium characterized by intra- and intercellular dark bodies, larger dark defects spanning several endothelial cells and bright irregular patchy areas crossing cell borders on the specular reflex were found in all eyes with FHC. Individual cell analysis did not reveal any significant differences in the endothelial cell density, cell area, coefficient of variation for cell area, cell perimeter, cell shape and in the number of endothelial cell apices between unoperated cyclitic and healthy fellow eyes. The mean cell density was 4.9% lower in the unoperated eyes with FHC than in the control eyes. A significant negative correlation was observed between the patients' age and the cell density both in the healthy and the cyclitic eyes. On the other hand, the correlation between follow-up period and cell density was not statistically significant in the cyclitic eyes. Although FHC does not seem to accelerate significantly the age-related cell density reduction, the magnitude of the cell loss found in the two operated eyes (45.5% and 49.8%) and in the eye with glaucoma (45.2%) may indicate altered tolerance against endothelial traumas in this disease.

“…At one month cell loss would reflect intraoperative factors. Although cell loss was significantly greater with the EC group, it was only 16.3%, and, with the mean loss of 10-7 and 10*9% respectively in the other groups, the results are within current claims, 14 '" which suggests that the surgery has been competently carried out. It is, however, a little surprising that the loss in the IC group with a twoplane iris supported lens was significantly less than in the EC group, which suggests that it is technically possible to execute the manoeuvres of implanting an iris-supported lens without undue trauma.…”

“…Anterior segment surgery causes endothelial cell loss and changes in the morphology of endothelial cells [10,[12][13][14][15][16][17]38]. Many authors have studied endothelial cell loss after cataract surgery, but very few after trabeculectomy [19][20][21].…”

“…Cataract surgery [9,[12][13][14][15][16][17][18], trabeculectomy [19][20][21] and combined phacoemulsification, intraocular lens implantation and trabeculectomy [22][23][24][25] cause endothelial cell loss; however, there are very few studies on this subject, and none has compared the effects of the combined method when the one-or two-step procedures are used.…”
