Blunt ocular injuries

Blunt ocular injuries

Blunt injuries to the eye can give rise to several problems, which include the following: /uni25CF Iritis . Inflammation; treated with topical steroids. /uni25CF Hyphaema (blood in the anterior chamber) ( Figure 49.20 ). Rest and sedation, particularly in children, ), are advised because the main danger in this condition is secondary bleeding, resulting in an acute rise in intraocular pressure and blood staining of the cornea. The use of antifibrinolytic agents ( ε -aminocaproic acid) has been advocated; if the pressure rises, surgery to wash out the blood may be necessary . /uni25CF Subluxation of the lens . This is suspected if the iris, or part of the iris, ‘wobbles’ on movement (iridodonesis). /uni25CF Secondary glaucoma . This is often associated with recession of the iridocorneal drainage angle. /uni25CF Retinal and macular haemorrhages and chor- oidal tears ( Figure 49.21 ). /uni25CF Retinal dialysis . This may lead to a retinal detachment and permanent damage to vision ( Figure 49.22 ).
