Sažetak

We measured the tamponading effect of silicone oil, saline and air after vitrectomy,
on intraocular pressure and aqueous humor outflow in 85 patients with highly proliferative
retina and vitreous changes. Silicone oil as retinal tamponading agent after
vitrectomy was used in 45 patients, and saline or air in 39 patients. The mean intraocular
pressure measured at one month after treatment was greatly elevated in patients
with silicone oil tamponade as compared to those with saline or air tamponade. At 6
and 12 months examinations, mean intraocular pressures were compared in these two
groups of patients. Gonioscopy revealed silicone oil emulsification and presence of emulsified
bubbles in the anterior chamber in 22.22% of patients, and narrowing of the
chamber angle in several patients with silicone oil tamponade. Intraocular pressure elevation
following vitrectomy with silicone oil tamponade was found to be of transient
rather than permanent nature, since it regressed after silicone oil removal. This transient
elevation was due to silicone oil tendency to emulsify. Silicone oil bubbles changed
the morphology of the anterior chamber angle and fine trabecular structures by creating
a barrier to aqueous humor outflow.
