ABSTRACTHereditary hypophosphatemic rickets are a group of diseases characterized by renal loss of phosphates. They appear with disharmonic hypogrowth and bone deformities. The most common form is the X-chromosome-linked hypophosphatemic rickets which is caused by inactivating mutations in PHEX gene. The objective of our work was to describe the ocular alterations and the clinical evolution in a patient with hereditary hypophosphatemic rickets and previous uveitis. Here is the case of a 9 years-old boy diagnosed with hereditary hypophosphatemic rickets, who was seen at the Uveitis Service of “Ramon Pando Ferrer” Cuban Institute of Ophthalmology. He presented with ocular pain and feeling of discomfort to light in his right eye. The ophthalmological exam yielded anterior uveitis with hypopyon in his right eye and crystal depots in the whole corneal thickness and the iris of both eyes. Topical steroids were prescribed to treat the inflammatory process. The findings in the anterior segment of the patients indicated the presence of cystinosis in which the accumulation of crystals is the most typical corneal alteration among the ocular manifestations. Its incidence reaches 90 % in under one year-old children and the first affected organs are the kidneys. The hereditary hypophosphatemic rickets may appear with corneal crystal depots and inflammatory processes in the anterior uvea.
