Moving Backward Is Not Retreating: Management of Pigment Dispersion Syndrome (PDS) Post Photorefractive Keratectomy (PRK)

Pigment dispersion syndrome (PDS) is a type of open-angle glaucoma characterized by the presence of pigments in the angle, on the trabecular meshwork as well as corneal endothelium. It remains underdiagnosed due to the lack of routine gonioscopy. Refractive surgeries such as laser vision correction can be complicated by this disorder and can lead to vision-threatening complications if left unchecked. In the following chapter we describe one such case of a young myopic male patient who underwent photorefractive keratectomy (PRK) at our center but then later went on to develop pigment dispersion syndrome. The management of the case and the clinical insights are discussed.
