A long-term (> 9 yr on average) study of choroid ruptures after accidents in 9 patients proved that healing of choroid ruptures took place in 2 stages. The early stage, which takes about 1/2 yr after the injury, is characterized by the presence of fast absorbing, usually massive preretinal hemorrhages and the development of the rupture . Soon pigment and/or proliferation can be seen in ruptures, whose course and shape can vary. The ruptures can remain, even permanently, without any pigmentation. The early stage includes dilatation of venous trunks and formation of half-transparent loops spanning the venous walls without changing its width. If the trauma simultaneously involved the retina, retinal changes disappeared considerably more slowly. The late stage takes place several years after an accident and includes gradual subsiding of pigmentation, slight changes in shape and course of ruptures, or even disappearance of the rupture. Visual functions in this type of injury are more endangered than those in the eye fundus; possible complications include secondary glaucoma, changes in lens position and traumatic cataract. Visual acuity in less complicated cases remains, in spite of the changes in the eye fundus, surprisingly good. A rare case of traumatic cataract regression, with the restoration of central vision, was observed. Oral administration of glycerin can accelerate absorption, especially in cases where a vitreous hemorrhage occurs. Careful examinations of intraocular pressure and retinal periphery should be performed.
