Persistent pupillary membrane.
A five year-old boy was referred to our hospital by an optom-etrist because of low vision. Slit lamp examination revealed severe thick pigmented persistent pupillary membrane (PPM) in both eyes (Figure 1). There were some points of attachment between membranes and lens, concerning the risk of cataract formation in the case of surgical removal. His visual acuity (VA) was 20/100 and 20/50 without...
متن کاملPeeling the Persistent Pupillary Membrane.
A 6-year girl of Indian ethnicity was referred for poor vision. Examination showed bilateral persistent pupillary membrane covering the central pupil. When pupil was dilated, iris strands were connecting the central 1.5 mm diameter circular membrane with the pupillary margins (Figure 1). Homatropine 2% eye drops, 12-hourly, and spectacle correction of astigmatism failed to improve acuities bett...

During embryonic development the lens receives nourishment from the posterior and anterior tunica vasculosa lentis. During the fourth month of gestation, macrophages play a role in the regression of the tunica vasculosa lentis, revealing the pupillary aperture posteriorly. The persistent pupillary membrane (PPM) represents a congenital remnant of the anterior tunica vasculosa lentis. As in this...
متن کاملPersistent Pupillary Membrane or Accessory Iris Membrane?.
Frequently, in literature and curent practice, accessory iris membrane (AIM) and persistant pupillary membrane (PPM) are confused. Both AIM and PPM are congenital iris anomalies in which fine or thick iris strands arrise form the collarette and obscure the pupil. AIM, which is also called iris duplication, closely resembles the normal iris tissue in color and thickness and presents a virtual se...
متن کاملSpontaneous hyphema and pupillary block in a patient with a left ventricular assist device.
The left ventricular assist device (LVAD) has been a standard of care for the management of patients with advanced heart failure since the 1990s. An increased risk of spontaneous bleeding related to the device has been noted, ranging from minor epistaxis to major thoracic and mediastinal hemorrhages. To our knowledge, intraocular hemorrhage has not been previously reported. We report a 72-year-...
