Basic Severity Score for Common Ocular Emergencies (Base Score): Posterior Segment

Description

Bourges et al reported the BAsic SEverity Score for Common OculaR Emergencies (BaSe SCOrE) to aid in initial triage of an ocular emergency based on the clinical severity. This can be helpful when an ophthalmologist is not readily available. The authors are from Paris Descartes School of Medicine, Universite Sorbonne and INSERM.

The scoring system recognized 4 categories: anterior segment, posterior segment, trauma and following ocular surgery.

Conditions affecting the anterior segment weighted in severity from 0 (least) to 6 (most) severe.

Category for Posterior Segment	Item	Median Severity Weight
acute binocular diplopia	without neurological symptoms	3
acute binocular diplopia	with neurological symptoms	5
choroidal new vessels (CNV) or direct complication	peripheral (exclusively)	2
choroidal new vessels (CNV) or direct complication	subfoveal	4
ischemic optic neuropathy	isolated	4
macula	macular edema	3
macula	macular hole	3
nonspecific visual symptoms	ophthalmic migraine	1
nonspecific visual symptoms	vitreous floaters	1
optic neuritis	without neurological symptoms	3
optic neuritis	with neurological symptoms	4
posterior segment inflammation	vitritis	3
posterior segment inflammation	retinal vasculitis	4
pupil disorder	no oculomotor disturbance	3
pupil disorder	with oculomotor disturbance	4
retinal artery occlusion	branch (BRAO)	4
retinal artery occlusion	central (CRAO)	5
retinal detachment	macula off	4
retinal detachment	macula on	5
retinal peripheral tear	detached edges, no retinal detachment	3
retinal peripheral tear	no detached edges, no retinal detachment	3
retinal vein occlusion	branch (BRVO)	3
retinal vein occlusion	central (CRVO)	4
toxoplasmosis, chorioretinal (active)	vitreous hemorrhage, isolated or unidentified cause	3
toxoplasmosis, chorioretinal (active)	foveal or peripapillary	4
toxoplasmosis, chorioretinal (active)	peripheral	3

Items not represented:

(1) ischemic optic neuropathy that is not isolated

(2) other forms of ocular toxoplasmosis
