Zahnfleischschwellung und Visusreduktion

Abstract

This case report describes the unilateral acute reduction of vision in the right eye of a 48-year-old woman. The patient was otherwise healthy but 2 days previously had suffered from dizziness and blurred vision. Secondary to this, the patient had already been under dental treatment for 1 week due to gingival swelling. At the first examination a macular branch retinal vein occlusion and Roth spots were found in the right eye by indirect ophthalmoscopy. The immediate diagnostic procedure identified aute amyeloid leukemia (AML) as the cause of the vascular pathology. The AML can be manifested in different ways and the retina is involved in approximately 50% of cases. Due to a secondary hyperviscosity syndrome, which is found in approx. 20% of acute leukaemias, symptomatic central vein occlusion or macular branch vein occlusion can occur. Ophthalmic symptoms can be the first and only signs to be detected. Therefore, ophthalmologists should also consider a systemic disease and initiate a clarification. A differential blood count is indispensable. The results usually improve by a rapidly arranged and suitable therapy. Ophthalmological follow-up examinations are imperative as an initiated chemotherapy can also produce ophthalmological side-effects.

Unilateral macular choroidal neovascularization—a rare manifestation in acute myelocytic leukemia

“…The proportion of cases with AML manifested in retina is high (approximately 50%), while ophthalmic manifestations could be the primary and only symptoms to be detected. [ 4 ] Besides, some ophthalmic symptoms have been documented as the signs of AML relapse, for example, choroidal effusion syndrome. [ 5 ] However, retinal neovascularizations are rarely observed and only saw in those with chronic disease.…”
