Ocular manifestations in the mucopolysaccharidoses - a review

Abstract: P>Ocular manifestations are very common in all types of mucopolysaccharidoses (MPS) and often lead to visual impairment. They arise as a result of the accumulation of glycosaminoglycans deposits in ocular tissues or secondary to increased intracranial pressure. Typical ocular features in MPS include corneal clouding, retinopathy, glaucoma, optic disc swelling, optic atrophy, and ocular motility and refractive error problems. This paper reviews the ocular features in patients with MPS, discusses the diagnosis of these ocular features and the diagnostic problems that may arise in patients (children) with MPS, and highlights the central role ophthalmologists may play in the diagnosis and follow-up of these patients.
