Benign Idiopathic Haemorrhagic Retinopathy (Colour Photography Posterior Segement, FFA)

Netzhaut -> Vaskuläre Erkrankungen
Patient: 21 year old female university student, RE VA sc 10/10, LE VA sc 10/10 . IOP 12 12 mmHg. No RAPD. Ishihara Test 17/17 both eyes. Anterior Segment examination is within normal limits in both eyes. Ocular medical History: RE visual disturbances. General Medical History: a thorough workup reveals two abnormal values- Hb 11.2 g/dl and MCV 61.9 fl, no history of systemic illness to explain the event and no history of physical exertion, exposure to high attitude, Valsalva maneuver, or trauma. Methods: Colour Photography Posterior Segement, FFA. Findings: Colour Photography Posterior Segement: RE fundoscopy reveals multiple intraretinal haemorrhages in the posterior pole. Both the optic nerve and the retinal blood vessels are within normal limits. LE fundoscopy is within normal limits. Fluorescein Angiography: blockage because of the haemorrhages with no leakage. Colour Photography Posterior Segement: RE fundoscopy, at 1 month f/u patient reports complete resolution of visual disturbances. Most of the haemorrhages had cleared. Discussion: Hb 11.2 g/dl and MCV 61.9 fl are not considered low enough to cause significant effect on the blood rheology. Retinal haemorrhages due to anaemia usually occur when haemoglobin is lower than 8 g/dl and almost always affects both eyes. The importance of this diagnosis is that the patient can be reassured that treatment is not required and that a return to a good level of visual acuity can be expected. Literature: 1.

Das trockene Auge ist eine der häufigsten Erkrankungen. Die Hyperosmolarität des Tränenfilms ist z.T. für die Veränderungen der Augenoberfläche und des Tränenfilms verantwortlich. Eine verminderte Tränensekretion und eine erhöhte Tränenfilmverdunstung sind mögliche Ursachen.
