Clinical Study of Indirect Traumatic Rupture of the Choroid

ABSTRACT

Indirect traumatic rupture of the choroid is a common sequela of contusion of the globe. Choroid is more prone to rupture than the other ocular coats because of the greater toughness of the sclera and the greater elasticity of the retina. Initially, a choroidal rupture may be obscured by a subretinal hemorrhage caused by tearing of the choriocapillaris. Later, after the blood has resorbed, a white curvilinear streak concentric to the optic disc is seen. Ophthalmoscopically, detection may be difficult, and fluorescein angiography may be required to reveal the presence or true extent of the choroidal rupture. The authors evaluated the clinical course of 34 cases of indirect rupture of the choroid at Department of Ophthalmology, Pusan Paik Hospital Inje University from January, 1984 to April, 1988. The results were as follows 1. The sex distribution revealed 28 male(82.4%) and 6 female(17.6%) but there was no significant difference in the laterality of affected eye. 2. The most prevalent age group was the twenties(35.3%). 3. The most common site of choroidal rupture was found in T group, which was the worst group in the final visual acuity.
