Purpose: To analyze the presence of hyperreflective foci in Type 1 and Type 2 diabetic patients, separately, without clinically significant diabetic macular edema and visual impairment.
Methods: Noninvasive, observational prospective study. Seventeen and 19 consecutive Type 1 and Type 2 diabetic patients (33 and 38 eyes), respectively, were recruited.
Purpose: To study retinal function in asymptomatic Type 1 and Type 2 diabetic patients with nonproliferative diabetic retinopathy (NPDR) and no clinical signs of diabetic macular edema.
Methods: Thirty-six consecutive Type 1 and Type 2 diabetic patients with nonproliferative diabetic retinopathy and no diabetic macular edema and 28 healthy controls underwent a complete ophthalmologic examination, including spectral domain optical coherence tomography and microperimetry.
Results: Seventy-one eyes (17 patients with Type 1 and 19 with Type 2 diabetes) were tested, and data from 36 (17 Type 1 and 19 Type 2) eyes were analyzed.
Purpose: To compare and analyze differences and similarities between Japanese and French patients in subtype diagnosis of exudative age-related macular degeneration (AMD) as determined by fundus photography (FP) and fluorescein angiography (FA), and a multimodal imaging involving FP, FA, indocyanine green angiography (ICGA), and optical coherence tomography (OCT).
Design: Retrospective chart review.
Methods: We determined the subtype diagnosis for 99 consecutive Japanese eyes and 94 consecutive French eyes with exudative AMD.
Background: To report the morphological macular findings detected by spectral domain optical coherence tomography (SD-OCT) and to determine their prevalence in patients with retinitis pigmentosa (RP).
Methods: SD-OCT scans of 176 eyes from 90 patients affected by RP were reviewed. A careful evaluation was carried out on photoreceptor inner/outer segment (IS/OS) junction, external limiting membrane (ELM), inner limiting membrane thickening (ILMT), epiretinal membranes (ERMs), retinal micropseudocysts (MPCs), cystoid macular edema (CME), macular holes (MHs) and choroidal neovascularization (CNV).
Purpose: To assess the effects of intravitreal bevacizumab injections in the treatment of juxtafoveal choroidal neovascularization associated with multifocal choroiditis.
Methods: Prospective interventional case series. Fourteen patients (14 eyes) affected by juxtafoveal choroidal neovascularization secondary to multifocal choroiditis were examined.
Purpose: To report the effects of intravitreal bevacizumab injection (IVBI) in a patient affected by retinal neovascularizations (RNVs) associated with myelinated nerve fibers (MNF) and complicated by vitreous hemorrhage.
Methods: A 23-year-old female was referred because of sudden visual acuity deterioration in the left eye. Nine years earlier, the subject underwent retinal laser photocoagulation for recurrent vitreous hemorrhages related to the development of RNV associated with MNF.
High-resolution spectral-domain optical coherence tomography of a patient affected by acute macular edema secondary to preeclampsia is described. The particular optical coherence tomography pattern was characterized by bilateral macular edema with a tent-shaped organization, associated with massive neurosensorial retinal detachment. Many hyperreflective irregular dots were evident in the context of a subfoveal clear cystic lesion.

Nowadays, the introduction of new, powerful diagnostic tools, such as spectral domain optical coherence tomography, and the widespread diffusion of intravitreal drugs, such as vascular endothelial grow factor inhibitors or implantable steroids, have dramatically changed the management and prognosis of RVO. The authors aim to summarize and review the main clinical, diagnostic, and therapeutic aspects of this condition.

Methods: Interventional case report.
Purpose: Spectral-domain optical coherence tomography (SD-OCT) enables high-resolution analysis of retinal layers and previously unseen hyperreflective dots (HRD). HRD morphological characteristics, evolution, possible origin and prognostic value are discussed.
Methods: We conducted a prospective study of 100 patients with exudative age-related macular degeneration (AMD), who were treated and followed up with monthly imaging examinations.
Purpose: To investigate the relationship between type of intraocular tamponade and unintentional retinal displacement after vitrectomy for rhegmatogenous retinal detachment.
Methods: Twenty-three eyes of 23 consecutive patients affected by rhegmatogenous retinal detachment underwent 3-port pars plana vitrectomy with gas (C3F8) or silicone oil (polydimethylsiloxane) tamponade. Ophthalmologic examination and fundus autofluorescence were performed before surgery (baseline) and at the 7-day, 1-month, and 3-month postoperative visits.
Purpose: To evaluate choroid thickness (CT) with RTVue spectral domain optical coherence tomography (SD-OCT) and the effect of age and myopia in eyes without posterior complications.
Methods: In this multicenter cross-sectional study, all enrolled patients were over age 18 and divided them in 3 groups based on refraction: emmetropia (+1 D to -1 D), mild myopia (-1 D to -6 D), and high myopia (-6 D to -20 D) groups. Horizontal scans through the fovea were acquired with RTVue OCT (Optovue Inc.
Aim: To report on the rebound macular edema (ME) effect following dexamethasone implant for the treatment of nonischemic central retinal vein occlusion (CRVO).
Methods: Twenty-one patients affected by ME secondary to central retinal vein occlusion (CRVO) underwent an implant of dexamethasone (700 μg) in a compassionate use program. The patients were followed up monthly.
Primitive retinal vascular abnormalities are benign conditions of the retinal circulation that comprise vascular tumors and telangiectasias. The principal vascular tumors of the retina include retinal capillary hemangioma, cavernous hemangioma of the retina, racemose hemangiomatosis of the retina and retinal vasoproliferative tumor, while primary retinal telangiectasias include Coats' disease, Leber's miliary aneurysms and idiopathic juxtafoveal telangiectasias. In most cases, these alterations result in significant visual impairment due to exudation determined by the structural abnormalities of the retinal vasculature.

A 43 year-old woman presented with bilateral vitritis and chorioretinal lesions compatible with "birdshot lesions". The patient was initially diagnosed with birdshot retinochoroidopathy and later on, during follow up, the occurrence of neurologic involvement and the lack of response to systemic immunosuppression led us to re-evaluate the diagnosis.

Diabetic macular edema is the major cause of visual acuity impairment in diabetic patients. The exact etiopathogenesis is unknown and, currently, grid/focal retinal laser photocoagulation represents the recommended treatment. It has been demonstrated that vascular endothelial growth factor (VEGF) plays a key role in the pathogenesis of diabetic macular edema by mediating vascular permeability and accumulation of intracellular and extracellular fluid, and thereby represents an appealing candidate as a therapeutic target for the treatment of diabetic macular edema.
