Pediatric traumatic cataract and surgery outcomes in eastern China: a hospital-based study

AIM: To evaluate the etiologies, management, and outcomes of pediatric traumatic cataract in eastern China. METHODS: Pediatric traumatic cataract were reviewed for demographic information, type of injury, mode of injury, time of injury, interval between injury and first visiting doctors, hospital of first visiting, surgeries, complications and prognosis. RESULTS: A total of 117 eyes of 117 patients (96 boys and 21 girls) with unilateral injuries (66 right and 51 left eyes) were included in the study. The mean (SEM) age at diagnosis was (6.6 +/- 3.2) years (range, 1.3-13.8 years). Each cataract was categorized according to the type of trauma: closed -globe (n=26) or open -globe (n=91) injuries. The most common injuring objects were sharp metal objects (37.61%). The most common complication in open -globe injuries was corneal laceration, whereas traumatic mydriasis was most common in closed -globe injuries. Of 68 eyes in patients with open-globe injuries who received cataract extraction, intraocular lens (IOLs) were primarily implanted in 47 eyes (68.12%), whereas 18 eyes with closed -globe injuries received cataract extraction, and IOLs were primarily implanted in 17 eyes (94.4%). The surgical procedures included reconstruction of the anterior segment, synechiolysis, excision of the membrane, lensectomy, vitrectomy and related techniques. Postoperative vision was significantly improved compared with preoperative vision. CONCLUSION: Pediatric traumatic cataract should be treated in time to attenuate the complications, and education on pediatric traumatic cataract and improvements in pediatric health care are needed for the early detection of cataract in children.
