Purpose

Persistence of the pupillary membrane (PPM) is a congenital pathology characterized by the persistence of Tunica vasculosa lentis anterior, which normally resolves during the third trimester by the apoptotic phenomena

Setting

Surgical resection of the pupillary membrane is the technique of choice in thick pupillary membranes that completely cover the visual axis, because of the major risk of amblyopia.

Methods

We report the case of a girl referred for an esotropia, at the ophthalmologic examination we found a dense bilateral pupillary membrane blocking the visual axis, 

Results

The persistence of the pupillary membrane (PPM) is a congenital disease, due to the persistence of the Tunica vasculosa lentis anterior, this vascular layer completely disappearss at the 8th month of embryonic life thanks to apoptotic mechanisms.

Most membranes are asymptomatic and require monitoring given the risk of amblyopia which must be managed early. The use of mydriatic eye drops in some patients allows the release of adhesions of the iris collar and their detachment from the anterior capsule

Surgical resection of the pupillary membrane is the technique of choice in thick pupillary membranes completely covering the visual axis with the risk of amblyopia.

Complications of this surgical technique are hyphema and cataracts when the membrane is vascularized adherent to the anterior crystalloid 

Conclusion

The persistence of the pupillary membrane obturating form is a severe pathology that requires rapid surgical management to avoid amblyopia, which must be systematically managed after the surgery.
