Inflammatory infiltration scoring rubric

Ocular region	Scoring system
Retina	Based on thickness of infiltration around blood vessels
	0: no infiltration
	1: 1–2 cell layers thick
	2: 3–4 cell layers thick
	3: 5+ cell layers thick
Subretinal space	0: no infiltration
	1: scattered individual cells
	2: moderate number of cells with some aggregates
	3: large numbers of cells causing expansion of the subretinal space
Choroid and episclera	0: no infiltration
	1: scattered individual cells
	2: moderate number of cells with some aggregates
	3: large numbers of cells causing expansion of the choroid space
Ciliary body	0: no infiltration
	1: scattered individual cells
	2: moderate number of cells with some aggregates
	3: large numbers of cells
Total infiltration score sum of all scores above (possible range 0–12)
