Kanhaiya Mittal, Rohan Chawla
A 21-year-old male presented with a chief complaint of night blindness since early childhood. The patient had no history of hemeralopia or photophobia, and no family history of such illness or use of glasses. On examination, his visual acuity was 6/6 in both eyes. Pupils were reacting normally. Dilated fundus examination revealed diffuse golden-yellow sheen throughout the fundus with prominent retinal vasculature, but arteries and veins were less distinguishable. Choroidal vessels were not visible. The patient was then patched and dark adapted for 6 hours...

Haiyan Wang, Fenge Chen, Hui Cao
The authors report a case of optical coherence tomography angiography (OCTA) features of retina and choriocapillaris before and after the surgical removal of a subfoveal perfluorocarbon liquid (PFCL) bubble. Before the surgery, the fovea avascular zone (FAZ) of both superficial and deep inner retinal layers (SRL/DRL) dramatically enlarged. However, after the removal, the FAZ continually decreased in both layers, even becoming close to normal in size. The abnormal choriocapillaris dark areas were also undetectable...

The ophthalmic manifestations of dengue fever include a visually impairing maculopathy, where patients are left with a central or paracentral relative scotoma. The authors present a case of a 26-year-old female patient returning from Thailand with unilateral reduction in visual acuity and a central scotoma associated with dengue fever. The authors report the use of the optical coherence tomography angiography (OCTA) as a noninvasive imaging platform to demonstrate its value in showing the persistent changes corresponding to the functional central scotoma in dengue-related maculopathy, which often cannot be visualized clinically or by standard OCT and fundus fluorescein angiography...

Giant cell arteritis (GCA) can present with cotton-wool spots in the retina and usually affects medium and large vessels. The authors present herein a 75-year-old man with GCA manifesting with cotton-wool spots and widespread retinal vasculitis affecting small-size retinal arterioles. The retinal vasculitis and the cotton-wool spots resolved after initiation of systemic corticosteroids and his vision returned to normal. GCA can uncommonly present with retinal vasculitis affecting small-size arterioles. [Ophthalmic Surg Lasers Imaging Retina...

Hsin-Ting Lin, Yun-Hsiang Chang
Von Willebrand disease (VWD) is characterized by bleeding symptoms that result in easy bruising, skin bleeding, prolonged bleeding from mucosal surfaces, heavy menstrual bleeding, and serious bleeding from the gastrointestinal tract. Early diagnosis and treatment are life-saving. This report is on a 47-year-old Taiwanese male with spontaneous, unilateral, droplet-shaped deep intraretinal hemorrhage. The patient presented in this case had no prior history of trauma, bleeding tendency, or coagulopathy. A diagnosis of VWD type 1 was made after von Willebrand multimer analysis...

Congenital retinal macrovessels (CRM) are rarely reported, aberrant, large branches of retinal vessels that can be both arteries and veins; however, they are more commonly veins that cross the horizontal raphe to either supply or drain the macula. In this brief report, the authors discuss optical coherence tomography angiography features of CRM in a 12-year-old male patient presenting with low visual acuity in the right eye since childhood. To the authors' knowledge, this is the first such report published in the literature...
