Basic Severity Score for Common Ocular Emergencies (Base Score): Anterior 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 Anterior Segment	Item	Median Severity Weight
anterior acute uveitis	first episode	2
anterior acute uveitis	iterative	3
conjunctivitis	noninfectious	1
conjunctivitis	viral	2
conjunctivitis	bacterial	2
contact lens	mechanical complication (dislocation, vacuum, etc)	1
contact lens	infectious keratitis without severity factor	3
contact lens	infectious with severity factors	4
corneal ulcer, not infected	unperforated with isolated epithelial defect	2
corneal ulcer, not infected	unperforated with stromal involvement	3
corneal ulcer, not infected	perforating	5
glaucoma	acute angle-closure	4
glaucoma	neovascular	4
keratitis	superficial punctate keratitis	1
keratitis	noninfectious interstitial keratitis	2
keratitis	infectious	3
lacrimal duct/gland	acute dacryocystitis	3
ocular surface burn	less than 9 clock hours of limbus and less than 75% of conjunctiva	3
pterygia	inflamed	1
scleral and episcleral inflammation	episcleritis	2
scleral and episcleral inflammation	scleritis	3

Items not represented:

(1) corneal ulcer, infected

(2) other forms of glaucoma

(3) ocular surface burn greater than limits given; this was included and set to grade 4

(4) fungal conjunctivitis
