title: [Automated perimetry analysis of optic nerve compression caused by orbital tumors and tumor-like lesions].
abstract: OBJECTIVE
  In order to evaluate the relationship between the orbital neoplasms and the resulting visual field damage.
  
  
  METHODS
  22 cases of orbital tumors and tumor-like lesions were examined with automated perimetry.
  
  
  RESULTS
  Visual field alterations varied from arcuate, inferior altitudinal, ceeocentral scotomas, to temporal hemianopsia and diffuse defect. The surgical removal of the tumor or steroid administration was followed by partial or full perimetric recovery.
  
  
  CONCLUSIONS
  Visual field alteration reflects the severity of the optic nerve damage. The impairment is reversible. Apical masses may cause severe optic neuropathy. Axonal and vascular factors are involved in the main pathological mechanisms of the disease.
