Poor outcome:final visual acuity <20/200

 

Factors associated with a poor outcome in >= 80% of patients (univariate analysis):

(1) endophthalmitis (100%)

(2) retinal detachment (100%)

 

Factors associated with a poor outcome in 40 to 79% of patients (univariate analysis):

(1) relative afferent pupillary defect (RAPD, 72%)

(2) initial visual acuity < 20/200 (57%)

(3) entry site cornea (60%) or sclera (43%)

(4) lens injury (45%)

(5) retinal break (46%)

 

Factors associated with a final visual acuity >= 20/40:

(1) corneosclera as entry point (83%)
