⁵M.D. Professor, İstanbul University Faculty of Medicine, Department of Ophthalmology, İstanbul/TURKEY Purpose: To investigate the surgical results in patients with traumatic cataract and assess the prognostic factors on visual acuity.
Material and Methods: Files of patients with ocular trauma treated between 1993-2008 in Istanbul University, Istanbul Faculty of Medicine, Department of Ophthalmology were reviewed retrospectively. Patients were analysed according to epidemiological features, clinical findings and applied surgical techniques.
Results: 157 eyes of 158 patient were studied. 37 patients (23.5%) were women, 120 (76.5%) were men (p<0.001). The mean age of the patients was 24.9 (2-78). Following trauma, 62 patients in the first 6 hours, 25 patients between 6-24 hours, 20 patients after 24 hours and 50 patients within 1 week after the trauma were admitted to the clinic. Of 157 patients 62.7% had penetrating trauma and 37.2% had blunt trauma. Initial visual acuity was 0.3 and under in all patients. Visual acuity of two patients were I (-) initially. 21% of patients had uveal prolapsus, 18% of patients had hyphema, and 10% of patients had traumatic mydriasis. Four patients had intraocular foreign body, six patients had retinal detachment and one patient has choroidal detachment . 27.8% of traumatic cataract cases was treated primarily and 72.1% was treated secondarily. Five patients with follow-up <6 months were not evaluated. Best corrected visual acuity was ≤0.3 in 83 patients, 0.3-0.6 in 38 patients, and >0.6 in 31 patients at final examination. Patients with blunt trauma had better prognosis compared to patients with penetrating injury. Patients with worse initial visual acuity had worse prognosis.
Conclusions: One of the most important factors that affect final visual acuity in traumatic cataract patients is initial visual acuity. Traumatic cataract may be treated primarly or secondarly, but better surgical results can be achieved in secondary surgery due to good wound healing and regression of inflammation.
