The newly developed Ocular Pressure Blood Flow Analyzer -OPFA- makes it possible to examine ocular circulation on both eyes simultaneously in a non-invasive, quick and reliable manner. The examination is easy to perform and well tolerated by the patient and requires no dilatation of the pupillae. It is an objective registration method with automatic analysis and evaluation and provides comprehensive data in form of print-outs and graphs.

Fields of application

  • Early detection and management of primary open angle glaucoma (POAG) resulting from impaired autoregulation
  • Early diagnosis and management of normal-tension glaucoma (NTG) resulting from reduced perfusion reserve
  • Identification of reduced autoregulatory capacity as a sign of transition from ocular hypertension (OH) to primary open angle glaucoma and initiation of an appropriate therapy
  • Determination of ocular perfusion pressures, ocular arterial pressures and ocular pulse blood volumes as the basis of glaucoma diagnosis and treatment control
  • Examination of ocular perfusion of retinal arterial and venous blockages, occlusion of the arteria ophthalmica or choroidal vascular abnormalities
  • Diagnosis and therapy control of arteriitis temporalis (Mb. Horton)
  • Assessment of ocular perfusion in supra-aortic arterial occlusion processes, pre- and post-operative
  • Monitoring of ocular perfusion in hereditary and degenerative retinal and choroidal diseases to evaluate progression
  • Ocular perfusion in age-related macula degeneration and macular dystrophie
  • Monitoring of ocular perfusion in diabetes and in diabetic retinopathies
  • Monitoring and management of ocular perfusion for patients with hypertony or hypotony and with vascular disregulation

Examination procedure

The procedure takes about one minute simultaneously on both
eyes with special scleral suction cups after local drop anesthesia -
pupil dilation is not required.
The examination produces an ocular perfusion pressure pulse
blood volume graph for both eyes showing the healthy or
diseased characteristics of ocular circulation.

The system is in medical clearance at the moment.
