Grading ocular symptoms in graft versus host disease (GVHD)

	GVHD score	Ocular symptom
Dry eye syndrome	0	No dry eye symptoms
	1	Dry eye symptoms not affecting activities of daily living (eye drops ≤3 per day) or asymptomatic signs of keratoconjunctivitis sicca
	2	Dry eye symptoms partially affecting activities of daily living (eye drops >3 per day or punctal plugs) without vision impairment
	3	Dry eye symptoms, significantly affecting activities of daily living (special eyewear to relieve pain) or unable to work because of ocular symptoms or loss of vision caused by keratoconjunctivitis sicca
Conjunctivitis	0	None
	1	Conjunctival hyperemia
	2	Conjunctival hyperemia with chemotic response and serosanguinous exudate
	3	Pseudomembranous conjunctivitis
	4	Pseudomembranous conjunctivitis with corneal epithelial sloughing and subsequent conjunctival scar and symblepharon formation
Cataract	1	Occasional subcapsular opacities and vacuoles in the central region of the lens
	2	Small clusters of subcapsular opacities remaining discrete
	3	Multiple clusters of subcapsular opacities that have mostly coalesced
