PURPOSE: To evaluate the visual prognostic factors in children with perforating ocular injury. MATERIAL AND METHODS: One hundred and seven eyes of the 107 patients were evaluated prospectively. Visual acuity at last control examination was accepted as final vision. Presenting visual acuities were grouped as between no light perception to hand movement (poor), counting finger to 0.05 (moderate), 0.1 to 0.4 (good), 0.5 to 1.0 (excellent). The effects of age, initial visual acuity, type of injury, location and extent of perforating ocular injury, presence of lens damage, intraocular foreign body, retinal detachment, hyphema and iris prolapsus, and time interval between trauma and operation on final vision were evaluated. Chi-square test was used for statistical analysis. Correlation analyses among some parameters were performed with Spearman's rho test. RESULTS: Seventy-four (69%) cases were males, and 33 (31%) were females. Mean age was found as 7.5±3.4 (3-15) years. Age of the patient (five years$geq$), poor initial visual acuity, large and posteriorly located wound, firearm injury, presence of intraocular foreign body, retinal detachment, hyphema, and lens damage were determined as effective prognostic factors on final vision. Time interval between trauma and operation and iris prolapsus had no effects on visual prognosis. CONCLUSION: Severe ocular injuries have limited visual acuity potential due to abundance of negative prognostic factors affecting visual prognosis in children with perforating ocular injury. Therefore, protective measures from ocular injuries for children were should be taken seriously.
