Purpose:.To interpret the incidence of optic-nerve maldevel-opment in postoperative pediatric cataract patients, and evalu-ate the clinical efficacy of administration of murine nerve growth factor (mNGF) in such patients.
Methods: Pattern visual evoked potential (P-VEP) was used to measure the visual pathway function in 28 cases (56 eyes) with bilateral congenital cataract and 13 cases (13 eyes) with unilateral congenital cataract who underwent cataract extrac-tion and intraocular lens implantation surgeries..The results were compared with 25 age-sex-matched healthy children (50 eyes)..mNGF was administered in 13 cases (23 eyes) who had visual pathway disorder..The efficacy of mNGF injection was observed. P100 latencies, which were used as a main parame-ter in P-VEP measurement, were analyzed statistically.
Results:.When compared with normal children, the P100 la-tency was significantly prolonged in the congenital cataract group (P<0.05). A significant improvement was noted in the visual pathway of subjects treated with mNGF (P<0.05).
Conclusion: Compared with normal children, the congenital cataract patients are more vulnerable to optic-nerve maldevel-opment. Murine NGF likely plays a protective and nutritive role in the development of optic nerve in cases of optic-nerve maldevelopment followed by congenital cataract surgery.
