title: [Analysis of optic nerve head by confocal scanning laser ophthalmoscope in ocular hypertension].
abstract: OBJECTIVE
  To analyze optic nerve head topography using confocal the scanning laser ophthalmoscope (CSLO) in ocular hypertension in comparison to normal eyes.
  
  
  METHODS
  We examined 25 patients with ocular hypertension and 27 normal controls. All of them had a complete ophthalmic examination. Optic nerve head analysis was performed by using a CSLO-type Heidelberg retina tomograph (HRT). The following stereometric parameters were evaluated: disc area, area and volume of cup, cup/disc ratio, area and volume of neuroretinal rim, mean and maximal cup depth, cup shape measure, height variation contour, mean retinal nerve fiber layer thickness, and retinal nerve fiber layer (RNFL) cross-section area.
  
  
  RESULTS
  In ocular hypertension eyes, rim volume, height variation contour and RNFL thickness showed a statistically significant reduction compared to normal eyes.
  
  
  CONCLUSIONS
  HRT appears to be an important tool in detecting early damage of retinal nerve fiber layer in ocular hypertension.
