Abstract

Purpose: Retinal changes secondary to hypotony are usually described as wrinkling or folding of the inner portion of the choroid, the retinal pigment epithelium (RPE), and the outer retinal layers in the macular area due to scleral wall collapse. We describe a new retinal finding in children with suspected hypotony after implantation of Baerveldt Glaucoma Implant (BGI). Observations: Four patients in our series developed significant RPE defects after BGI implant. The RPE defects appeared as elongated white lines observed solely in the posterior pole, in no particular pattern, and seemed to be worse in infants with anterior segment dysgenesis and with collagen disorders. Conclusion and importance: Children have thinner and more elastic scleral walls than adults. This characteristic may cause the inward scleral wall to collapse when the eye is hypotonic. The resulting redundancy of the retina leads to wrinkling and RPE defects characterized by hypopigmented lines predominantly in the macular area. Such findings, to our knowledge, have not been previously reported in pediatric patients.
