          As already mentioned, vision that has been lost due to glaucoma
        
        
          is irreversible. Considering that glaucoma is a progressive disease,
        
        
          treatment must commence immediately as soon as it is diagnosed.
        
        
          The therapeutic approach for glaucoma primarily aims at lowering
        
        
          intraocular pressure. This can be done either by medication, laser, or
        
        
          surgical intervention.
        
        
          Treating glaucoma
        
        
          The new digital photography techniques allow an exact three-
        
        
          dimensional portrayal of the optic disc. Consequently the anatomical
        
        
          changes in glaucoma can be studied more precisely than with a simple
        
        
          fundoscopy.
        
        
          These photographs are kept in a patient’s files for future reference.

          Moreover, patients that already suffer from glaucoma can be
        
        
          monitored over time for the development of the disease and the
        
        
          effectiveness of the treatment.
