OCULAR MANIFESTATIONS OF PRIMARY MYELOFIBROSIS.

To report ocular manifestations of idiopathic primary myelofibrosis in a patient with relapsed primary myelofibrosis. Observational case report. A 57-year-old African American male with history of primary myelofibrosis, diagnosed by bone marrow aspirate and biopsy, believed to be in remission was referred to us for bilateral angle-closure glaucoma refractory to medical treatment and laser peripheral iridotomy. His fundus examination revealed serous retinal detachments, choroidal effusions, and Roth spots, and B-scan revealed his angle closure was due to annular anterior ciliochoroidal effusions. The patient was taken to surgery for a pars plana vitrectomy with radial sclerotomies performed to relieve the patient's eye pressure in the left eye. Cytologic analysis of the choroidal effusions revealed neutrophilic infiltrates with immature forms and erythroid precursors, suggesting a neoplastic infiltration from the patient's primary myelofibrosis. The patient's vision and ocular symptoms significantly improved after chemotherapy. Repeat bone marrow aspiration and biopsy confirmed the patient's primary myelofibrosis with no progression to acute leukemia despite his high leukocyte count. Neoplastic infiltration of primary idiopathic myelofibrosis into the eye and surrounding structures, which is scantly described in the current literature, may be an early sign of new onset or relapsing primary myelofibrosis. Chemotherapy can be very effective in the ultimate treatment and remission of these ocular symptoms.
