TABLE 2.

European Union directive visual field requirements and comparison of the requirements among selected European countries according to the degree of deviation.

	EU directive (2006/123/EC)	Horizon at a visual field of at least 120°, the extension must be at least 50° to the left and right and 20° up and down. There must be no scotomas in the radius of the central 20°
Countries with a small	Slovenia	Same requirements
derogation or the same	Italy	Same requirements
conditions as the EU directive	Hungary	Same requirements
	Austria	Same requirements
	Switzerland	Same requirements
	France	Same requirements
	Denmark	Same requirements
Countries with a major	Croatia	Mentions only the criteria that there should be no scotomas in the radius of the central 20°
deviation -in less strict direction:	The Netherlands	The field of vision is examined only if there are deviations in the questionnaire, otherwise not (in case the person needs an extended ophthalmology examination, the same criteria as in the EU directive are observed)
	Germany	Visual field is tested only if the candidate does not have adequate acuity on the initial vision test (then the same criteria as in the EU directive are observed)
	United Kingdom	Visual field is tested only if the candidates have to undergo an extended examination because they failed to read the license plate (then the same criteria as the in the EU directive are observed)
	Iceland	Opportunity to self-certify that no visual impairment is present. If not, visual functions are not tested. If there are problems, the same criteria as in the EU directive.
Countries with a major	Norway	If there is suspection of visual field deficit, Esterman perimetry is performed. No more than four missed test points within 20° are allowed.
deviation -in stricter direction:	Sweden	In threshold perimetry, all corresponding test points within 20° need to be at least 10 dB and all corresponding test points within 10° need to be 20 dB or more. Not more than two adjacent missed points within 120° horizontally and 40° vertically in Esterman perimetry.
