Ambrisentan (Letairis; Gilead Sciences, Foster City, CA) is an endothelin receptor antagonist approved by the U.S. Food and Drug Administration for the treatment of pulmonary arterial hypertension. The authors describe the occurrence of bilateral cotton wool spots soon after initiation of ambrisentan treatment in a 29-year-old woman. Fluorescein angiography, optical coherence tomography, and fundus autofluorescence were performed. After discontinuation of ambrisentan, the cotton wool spots resolved without recurrence. To the authors' knowledge, this is the first report of retinopathy in the form of cotton wool spots associated with the use of an endothelin receptor antagonist.

Hypertensive retinopathy is well known, but choroidopathy is uncommon and associated with acute increases in blood pressure. Nonperfused areas of the choriocapillaris lead to changes of overlying retinal pigment epithelium (RPE), resulting in neurosensory or RPE detachments. The authors describe two patients with serous retinal detachments associated with acute arterial hypertension in pre-eclampsia and HELLP (hemolysis, elevated liver enzyme levels, and low platelet count) syndrome. Subretinal fluid was demonstrated on ultra-widefield fundus imaging and optical coherence tomography. Fluorescein angiography and indocyanine green angiography enabled imaging of the choroidal hypoperfusion. All signs and symptoms resolved after 1 and 3 months, respectively, with persistent macular pigmentary changes in both patients.

A 55-year-old male presented with serous retinal detachment over 3 months in his right eye. His left eye was blind due to retinal pigment epithelium detachment since 1997 with atrophy of the neurosensory retina. Fluorescein angiography had previously shown bilateral polypoidal choroidal vasculopathy (PCV). Optical coherence tomography (OCT) confirmed PCV with central involvement. The patient underwent intravitreal injections of 6x Lucentis, 4x Avastin and one injection of aflibercept. PCV recurred from 1 to 4 months after each treatment. The patient had history of stroke, hypertension, and atrial fibrillation and was started on oral eplerenone 25 mg/day in October 2014, which resulted in a long-term ongoing complete retinal reattachment. OCT ganglion cell and inner plexiform layers showed full recovery of the fovea in the right eye and irreversible in the left eye. Low-dose eplerenone may resolve recalcitrant PCV with central involvement. The duration of treatment remains uncertain.

A 61-year-old woman visited us with recent onset right-side weakness. Magnetic resonance imaging showed ischemic changes at the left internal border zone due to occlusive disease affecting the left proximal internal carotid artery. Prompt oral dual antiplatelet therapy and intravenous fluid were administered with subsequent induced hypertension and without reperfusion therapy. Although the hemiparesis was improved, she complained of a new-onset transient left-side monocular visual loss. Fluorescein angiography confirmed delayed perfusion in the left eye. We performed extracranial-intracranial bypass for flow augmentation. After bypass, the amaurosis fugax resolved. Follow-up retinal fluorescein angiography also showed improved retinal perfusion.
