Introduction: Anterior ischemic optic neuropathy (AION) is an ischemic disorder of the optic nerve and a common cause of acute, painless, permanent vision loss. It is divided into two types: arteritic AION (AAION) and non-arteritic anterior ischemic optic neuropathy (NAION). Although subretinal fluid associated with optic disc edema has been reported in cases of NAION, it is rarely described in AAION. Case Presentation: An 86-year-old female with a history of polymyalgia rheumatica presented with sudden vision loss in the left eye. Initial examination revealed left pallid optic disc edema with peripapillary hemorrhages. Optical coherence tomography (OCT) of the left macula showed intraretinal and submacular fluid. The patient was started on 50 mg of oral prednisone daily. The diagnosis of giant cell arteritis (GCA) was later confirmed with a positive temporal artery biopsy. Three weeks after presentation, an OCT was completed which demonstrated complete resolution of the intraretinal and submacular fluid. Although the presence of both intraretinal and subretinal fluid has been previously documented in cases of NAION, it is rarely reported in a patient with GCA. Conclusion: This is a newly described case of subretinal and intraretinal fluid in a patient with AAION. We postulate that the pathophysiology behind this is mediated by associated choroidal ischemia leading to altered permeability. OCT is an important imaging modality allowing for signs of GCA to be better characterized.

Central serous chorioretinopathy (CSCR) is a retinal disease that may be complicated by the development of serous retinal pigment epithelial detachment (PED). The exact molecular mechanisms of CSCR have remained uncertain as well as there is no effective medical therapy. Herein, we describe a case of a 43-year-old male suffering from chronic CSCR with PED and visual acuity reduction (20/40) that showed improvement in visual acuity (20/25) and metamorphopsia 2 weeks after daily intake of 20 mg sildenafil tablets. Optical coherence tomography (OCT) scan showed resolution of PED with residual degeneration of the photoreceptor inner and outer segment layer and retinal pigmented epithelium. The patient continued treatment with sildenafil 20 mg for 2 months. Six months after the discontinuation of therapy, visual acuity was maintained, with absence of PED at OCT. Our case supports the hypothesis that phosphodiesterase type 5 (PDE-5) inhibitors may be an alternative in the treatment of patients with CSCR, alone or combined with other medications.
