    Endoscopy can aid treatment of pediatric nasolacrimal duct obstruction

    Cycloplegic refraction beneficial for patients at initial, follow-up exams


    The current literature shows an over a 94% success rate for endoscopic surgery in the treatment of PNLDO, Dr. Silkiss added.

    Importantly as well, PNLDO is associated with higher rates of anisometropia (8.6% versus 0.66% in the general population) and amblyopia (5.8% versus 1.6% to 3.6%). All children treated for PNLDO therefore should undergo a cycloplegic refraction at the initial and follow-up exams.

    “Endoscopic surgery for PNLDO has come into its own in the past few years,” she said. “I would highly encourage other ophthalmologists to use endoscopy. It is wonderful to be able to see anatomy that you have never been able to visualize before with such clarity and deal with difficult blockages with greater precision.”
