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...

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...

A 74-year-old man presented with right eye pain, swelling, photophobia, and vision loss 1 month following placement of an intravitreal dexamethasone implant (Ozurdex; Allergan, Irvine, CA) for intraocular inflammation refractory to topical therapy. Clinical examination showed visual acuity of 20/400, anterior chamber cell, vitritis, retinal vasculitis, and extensive retinitis. A vitreous biopsy was performed followed by intravitreal injections of vancomycin, ceftazidime, ganciclovir, and clindamycin. Polymerase chain-reaction testing was positive for Toxoplasma gondii...

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...

This prospective retinal imaging case series was designed to establish feasibility of plenoptic ophthalmoscopy (PO), a novel mydriatic fundus imaging technique. A custom variable intensity LED array light source adapter was created for the Lytro Gen1 light-field camera (Lytro, Mountain View, CA). Initial PO testing was performed on a model eye and rabbit fundi. PO image acquisition was then performed on dilated human subjects with a variety of retinal pathology and images were subjected to computational enhancement...

BACKGROUND AND OBJECTIVE: Submacular fluid (SMF) can persist for months to years following rhegmatogenous retinal detachment (RD) repair. The authors' objective was to describe fundus autofluorescence (FAF) and optical coherence tomography (OCT) findings associated with the absorption of persistent submacular fluid (SMF) following RD repair. PATIENTS AND METHODS: Retrospective review of clinical data and FAF and OCT imaging from sequential postoperative visits in a cohort of patients with persistent SMF following RD repair...

BACKGROUND AND OBJECTIVE: To compare the visualization of microaneurysms (MA) and the foveal avascular zone (FAZ) area using optical coherence tomography angiography (OCTA) versus fluorescein angiography (FA) in patients with diabetic macular edema (DME). PATIENTS AND METHODS: Patients were prospectively recruited for same-day imaging on spectral-domain OCTA and FA. OCTA images were automatically segmented into superficial (sOCTA) and deep (dOCTA) capillary plexuses...

BACKGROUND AND OBJECTIVE: To identify characteristic choroidal changes of patients with Vogt-Koyanagi-Harada (VKH) disease at different stages. PATIENTS AND METHODS: Fifty-four patients with VKH in the acute uveitic or convalescent stages, 24 patients with central serous chorioretinopathy (CSC), and 54 normal participants were enrolled in this prospective, observational study. Enhanced depth imaging spectral-domain optical coherence tomography scans were captured for all subjects to allow for comparison of choroidal morphological findings...

BACKGROUND AND OBJECTIVE: Optimal placement of the Argus II Retinal Prosthesis System (Second Sight Medical Products, Sylmar, CA) is critical. Intraoperative optical coherence tomography (OCT) allows for intrasurgical visualization and confirmation of array placement. In this study, two different OCT systems were evaluated to assess the feasibility and utility of this technology during Argus II surgery. PATIENTS AND METHODS: Intraoperative OCT was performed on five patients undergoing Argus II implantation at Cole Eye Institute from June 2015 to July 2016...

BACKGROUND AND OBJECTIVE: To evaluate predictors of visual outcomes and microbial profile in endophthalmitis. PATIENTS AND METHODS: This was a prospective, interventional case series at a tertiary eye care center. Of the 207 patients included, 83 had post-cataract surgery endophthalmitis (PCE), 84 had post-traumatic endophthalmitis (PTE), and 16 had endogenous endophthalmitis. Vitreous samples were evaluated for microbial profile, and all patients received similar empirical antibiotic therapy...

BACKGROUND AND OBJECTIVE: To evaluate the safety and efficacy of 0.3 mg ranibizumab (Lucentis; Genentech, South San Francisco, CA) in eyes with persistent diabetic macular edema (DME) after recent, chronic, and frequent bevacizumab (Avastin; Genentech, South San Francisco, CA). PATIENTS AND METHODS: Open-label, prospective study of 0.3 mg ranibizumab for eyes with persistent DME after bevacizumab. Thirty eyes randomized to a sustained group or a pro re nata (PRN) dosing group...

The authors present an incidentally noted pigmented anterior vitreous cyst in an asymptomatic male adult. Observation was elected. Stability during the course of 2 years and mobility of the vitreous cyst using dynamic imaging are demonstrated. [Ophthalmic Surg Lasers Imaging Retina. 2016;47:975-977.].

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...

The authors report the use of optical coherence tomography angiography (OCTA) (DRI OCT Triton; Topcon, Tokyo, Japan) to localize, characterize, and confirm the presence of a choroidal neovascular membrane in a patient of focal choroidal excavation (FCE) with recent-onset metamorphopsia and visual blurring. En face OCTA images just above the level of the retinal pigment epithelium-Bruch's membrane complex typically showed the presence of a glomerulus-like neovascular network with an adjacent dark area suggestive of a Type 2 choroidal neovascularization (CNV)...

Portable, hand-held optical coherence tomography (OCT) revealed three clinically relevant yet not ophthalmoscopically detected or confirmed manifestations of retinoblastoma in a single patient with familial bilateral disease. Specifically, OCT showed new retinal tumors, new vitreous seeds, and tumor recurrence before they could be detected or confirmed by ophthalmoscopy.
