Microglia, the principal resident immune cell in the retina, play constitutive roles in immune surveillance and synapse maintenance, and are also associated with retinal disease, including those occurring in the macula. Perspectives on retinal microglia function have derived largely from rodent models and how these relate to the macula-bearing primate retina is unclear. In this study, we examined microglial distribution and cellular morphology in the adult rhesus macaque retina, and performed comparative characterizations in three retinal locations along the center-to-periphery axis (parafoveal, macular, and the peripheral retina)...

PURPOSE: To report a family affected by familial exudative vitreoretinopathy (FEVR) in which more severe disease phenotypes segregated with digenic rather than monogenic variants in FEVR-related genes. METHODS: Phenotype was documented with high-resolution imaging of retinal structure and wide-field fundus photography. Next-generation sequencing (NGS) of known genes involved in FEVR was performed. RESULTS: Three affected individuals within a family with FEVR presented with variable disease severity...

Retinitis Pigmentosa (RP) has been reported to be associated with retinal hemangioma, retinal angiomatous proliferation, polypoidal choroidal vasculopathy and vasoproliferative tumours. However there is no previous report of choroidal nevus in an eye with RP. We describe such a case in which the eye with RP had a choroidal nevus at the macula. The coexistence of these two entities in the same eye emphasizes the need of careful examination of patients with RP. The presence of choroidal nevus warrants additional investigations such as B scan ultrasonography and a close follow-up to pick up changes in the nevus size and morphology...

Importance: Optical coherence tomographic angiography (OCT-A) is able to visualize retinal microvasculature without the need for injection of fluorescein contrast dye. Nevertheless, it is only able to capture a limited view of macula and does not show leakage. Objectives: To evaluate the retinal microvasculature using OCT-A in patients with type 2 diabetes as well as the association of OCT-A characteristics with diabetic retinopathy (DR) and systemic risk factors...

PURPOSE: To evaluate and compare the effect of silicone oil and gas on the thickness of all retinal layers in eyes with macula-on retinal detachment (RD). METHODS: Three hundred and sixty-seven eyes of 367 patients who received silicone oil tamponade and 310 eyes of 310 patients who received gas tamponade for the treatment of rhegmatogenous RD were initially reviewed. Automated retinal segmentation method using Spectralis optical coherence tomography was used for analysis...

Purpose. To report unusual presentation of type 1A idiopathic macular telangiectasia (IMT). Methods. Two middle-aged women with bilateral IMT were examined. Results. Both patients presented with a gradual vision loss in both eyes. Fundus examination was unremarkable in one case and showed small macular telangiectasia in both eyes in the other case. Fluorescein angiography (FA) revealed early bilateral macular punctuated hyperfluorescence corresponding to the dilated capillaries in both cases. FA and fundus examination confirmed also the absence of vascular abnormalities in the middle or anterior fundus periphery in one case...

PURPOSE: To report a case of atypical syphilitic uveitis complicated with retinal vasculitis, proliferative retinopathy, and vitreous hemorrhage in which vitreous surgery was useful for the diagnosis and treatment. CASE REPORT: A 38-year-old female was referred to our hospital after noticing visual disturbance in her right eye. Fundoscopy examination of that eye revealed retinal phlebitis accompanied by retinal hemorrhage and soft exudate, and remarkable exudative changes in the retinal vessels from the upper arcade to the macula region...

PURPOSE: We present an atypical case of submacular fluid leading to serous macular detachment. METHOD/PATIENT: A 69-year-old man was evaluated for metamorphopsia in the left eye. RESULTS: Best-corrected visual acuity was 20/25 in both eyes. He had undergone cataract surgeries in both eyes 12 years ago. The axial length was 25.93 mm (OD) and 24.12 mm (OS). Optical coherence tomography showed posterior staphylomas and subretinal fluid on the superior border of the staphylomas in both eyes; in the left eye, submacular fluid was noted extending up to the macula...

A 65-year-old Caucasian male presented to the eye emergency department with bilateral significant visual loss. He was otherwise healthy with no significant past medical history. Ophthalmic history was significant for chronic open-angle glaucoma, for which the patient was using latanoprost once daily to both eyes. There was no preceding history of trauma or ocular surgery and the patient was emmetropic. Two weeks prior to his presentation, he reported a headache, which settled spontaneously. Slit-lamp examination demonstrated bilateral keratic precipitates, bilateral significantly shallow anterior chamber, and bilaterally normal intraocular pressures of 16 mm Hg...

PURPOSE: To investigate the clinical features associated with early visual loss in patients with idiopathic epiretinal membrane. METHODS: Patients with idiopathic epiretinal membrane with visual acuity of ≥20/40, intact ellipsoid zone, and follow-up duration of at least 24 months were included in this retrospective age-matched control study. The disk-fovea-vascular (DFV) distance, central macular thickness, membrane configuration, and ellipsoid zone were assessed using fundus photography and spectral domain optical coherence tomography...

PURPOSE: To compare the visualization of the macula between spectral domain optical coherence tomography (SD-OCT) and swept-source OCT (SS-OCT) in gas-filled eyes. METHODS: Sixty-one patients with common indications of gas tamponade, including 27 with macular holes and 34 with rhegmatogenous retinal detachment, who were treated with vitrectomy and gas tamponade were imaged using both SD-OCT (3D-OCT 2000, Topcon, Tokyo, Japan) and SS-OCT (DRI-OCT, Topcon) at 1, 3, and 7 days after the surgery...

To identify the cause of a sudden binocular vision decrease in patients with retinitis pigmentosa and bilateral idiopathic demyelinating optic neuritis is difficult, but early diagnosis and treatment significantly improve the prognosis. Here, we report a 6-year-old boy with a progressive binocular vision decrease in 38 days. The patient had a history of night blindness, a mottled retina without pigmentation, extinguished electroretinographic response, tritanopia, and an absent ellipsoid zone outside the macula fovea by optical coherence tomography in both eyes...

BACKGROUND AND PURPOSE: To analyze treatment plan robustness and plan optimization strategies of (106)Ru eye plaque brachytherapy using a novel software tool. MATERIALS AND METHODS: A treatment planning software was developed that allows to calculate dose-volume metrics. Plaque misplacements were simulated and evaluated with respect to the effect on tumor coverage and dose changes in critical structures. Two treatment plan optimization approaches were analyzed: (a) reducing plaque size and (b) shifting the plaque away from organs-at-risk (OAR)...
