Objective: To observe the ocular histopathological changes aftereyeball enucleation induced by ceal trauma.Methods: Light microscopic examination was done on 117 eyeball specimens enucleated after ceal trauma (18 with ceal fissure and 99 with ceal perforating trauma).Results: Acute, subacute or chronic inflammatory changes, and fibrous membrane formation were observed in well-closed ceal wounds, whereas inflammation, atrophy and scar were observed in the focal tissues. But at the late period, secondary glaucoma, retinal detachment, endophthalmitis and eyeball atrophy resulted in blindness. Ceal fistula was observed in those with inadequate cure of wounds caused by ingrowth of ceal epithelium, embedment of iris and vitreous body, and large area of centrally located tissue deficiency of the ceal. A high incidence of endophthalmitis was noted due to the presence of ceal fistula. Severe inflammation was observed in the anterior segmental tissues with fibrous infiltration in the anterior chamber, which might result in rapid destruction of the eyeballs.Conclusions: Ocular pathology varies with the difference of the position, form, size and closing conditions of the ceal laceration after trauma.
