Risk	Guideline	Clinician
Low	Family history only/no glaucoma	Discharge
	OHT < 24 mmHg
	Glaucoma suspect unchanged over 3+ years
Low	Stable OHT and glaucoma suspect	COGS
	On/off treatment
	Once baseline imaging completed in HES
	Includes PDS/PXF
	POAG (MD < 12 dB), stable on 2 consecutive occasions. Can include post-trabeculectomy > 24 months
	No dense lens opacity
	Not on hospital transport or limited mobility
	Does not require OCT for definitive management
Low	As for community low risk but requires transport/community not possible due to mobility issues/if regular OCT required	Virtual hospital clinic
Low	Community returns for consideration of discharge	Consultant
Moderate	Secondary glaucoma or OHT	COGS
	Angle closure patients
	Stable moderate to advanced glaucoma (MD > 12 dB), stable on 2 occasions, can include post-trabeculectomy > 12 months
	Only eye any diagnosis
	No dense lens opacity
	Not on hospital transport or limited mobility
	Does not require OCT for definitive management
Moderate	Post-laser or medication change	AGC: nurse led
Moderate	Glaucoma progression is suspected	AGC: doctor or optometrist clinics
	Pre- and post-cataract assessments in glaucoma patients
	Post-op trabeculectomy < 12 months but >2 months
High	Unstable advanced glaucoma	AGC: consultant slot
	For consideration of surgery
	Post-op trabeculectomy/tube/other (<2 months)
