Choroidal rupture and optic atrophy.

Abstract

The association between post-traumatic optic disc pallor and traumatic choroidal rupture is poorly understood. To further define this relationship, nine cases of indirect traumatic choroidal rupture and post-traumatic optic disc pallor were compared with cases of indirect choroidal rupture without disc pallor in terms of severity of ocular injury, fundus findings, and visual outcome. The type and severity ofthe injury did not appear to influence the risk of optic disc pallor. Optic disc pallor was associated with a slightly poorer long term visual acuity than eyes without pallor (p=0059). The presence of a relative afferent pupillary defect was strongly associated with optic disc pallor (p=0016). Peripapillary retinal pigment epithelial abnormalities were a common finding, suggesting peripapillary trauma as a cause for optic disc pallor.

“…Choroidal ruptures are breaks in the retinal pigment epithelium, Bruch's membrane, and choroid that occur in 5% of blunt ocular trauma [4]. CR may be complicated with haemorrhagic or serous macular detachment, optic disc pallor, and choroidal neovascularization [1]. The formation of CNV must consider the distance of the CR from the fovea and the length of the break [2].…”

“…Choroidal rupture is a break in the choroid, Bruch membrane, retinal pigment epithelium (RPE) that results from blunt ocular trauma. In most cases choroidal ruptures are secondary to indirect trauma, non-penetrating closed-globe blunt trauma [1]. After blunt trauma, the ocular globe undergoes mechanical compression and then sudden hyperextension.…”

Multimodal Imaging in a Patient with Traumatic Choroidal Ruptures

“…In this latter case, it is supposed that the trauma causes an anteroposterior globe compression and, thus, a sudden increase of IOP following an equatorial plane producing a shear force concentric to the optic disc, which results in peripapillary curved ruptures. Choroidal ruptures may be complicated by subretinal hemorrhage, macular damage, choroidal neovascularization (CNV), and optic disc pallor (3).…”

“…Blunt ocular trauma is the most common eye injury seen in emergency rooms. Acute complications of such a trauma are optic neuropathy and choroidal rupture (1), while secondary complications include choroidal neovascularization. All patients presenting with blunt ocular trauma should undergo a fundus examination after pupillary dilation to exclude damage to the optic nerve, retina, and choroid, and need close followup to manage the development of secondary complications.…”

Choroidal Rupture

“…Larger than expected scotomas may be due to overlying nerve fiber layers-for example, an inferior altitudinal defect from a rupture superior to the disc 34 -or due to an associated traumatic optic neuropathy. 35 In many cases, the etiology of the visual field defect is unclear.…”
