RESUMEN
OBJECTIVE: To report the ocular manifestations in patients with leukaemia. METHODS: This is a retrospective, descriptive and observational study in patients with ocular manifestations of leukaemia. RESULTS: A total of 14 eyes were evaluated corresponding to 8 patients (5 women and 3 men) with ocular manifestations of leukaemia. The mean age at diagnosis was 43 years (31-76 years). Six eyes corresponded to patients with acute myeloid leukaemia (AML), four eyes to acute lymphoid leukaemia (ALL), two eyes to chronic myeloid leukaemia (CML), and the remaining two belonged to patients with hairy cell leukaemia (HCL). The primary ocular findings were choroidal invasion in 12 eyes (85.7%), retinal infiltration in 4 eyes (28.6%), and neuro-ophthalmic disorders in 4 eyes (28.6%). The mean visual acuity improved from 0.689 to 0.449 (logMAR) (P=.012) after the systemic and intrathecal chemotherapy. Of the eight patients, four died from systemic complications of the underlying disease. CONCLUSIONS: This is the first report of multiple ocular manifestations secondary to leukaemia in a Colombian population. It is important to keep in mind that this disease is included within the masquerade syndromes and that the ophthalmological findings that, while subtle, can also be devastating and be signs of a life-threatening disease.
RESUMEN
OBJECTIVE: To report the indocyanine green videoangiography (ICG-V) characteristics of optociliary veins (OV) in optic nerve sheath meningioma (ONSM). DESIGN: Case series. PARTICIPANTS: Four eyes (patients) with OV and ONSM were examined. INTERVENTION: Indocyanine green videoangiography and intravenous fluorescein angiography (IVFA) were prospectively performed. MAIN OUTCOME MEASURES: The course of OV in ONSM cases was observed with ICG-V and IVFA. RESULTS: On ICG-V, the course of OV was followed from their origin at small tributaries of the central retinal vein, their junction with choroidal veins, and finally to their drainage in the vortex venous system. The authors found an inverse relationship between the degree of optic disc edema and the development and ease of visualization of the optociliary veins and their draining course through the choroidal circulation. The mean time from the injection of indocyanine green to the visualization of OV's draining choroidal vessels was 35.4 seconds (range, 25.4-50 seconds). Intravenous fluorescein angiography allowed visualization of OV only at the margins of the optic disc in all cases. CONCLUSION: Indocyanine green videoangiography provides important and new information in cases with OV and ONSM that is not obtained with IVFA. Such information may provide important knowledge regarding the hemodynamics of the choroidal circulation in normal and pathologic states.
