In addition to routine ophthalmic tests such as measuring tear production and fluorescein staining, the following specialized diagnostics are available:

  • Tonometry (measuring intraocular pressure)
  • Electroretinography (evaluates the health of the retina)
  • Ocular ultrasound
  • Gonioscopy (examination of the filtration angle in the eye for at-risk glaucoma patients)
  • Blood pressure measurement (for hypertensive retinal detachment)
  • Retinal imaging
  • Imaging of the orbit and surrounding tissues by computed tomography (CT) or magnetic resonance imaging (MRI)
  • Dacryocystorhinography (imaging of the nasolacrimal system)
  • Diagnostic intraocular aspirates including aqueous, iris, vitreous and subretinal
