Purpose: To evaluate the photoreceptor layer in eyes with branch retinal vein occlusion associated with macular ischemia, using a method of en face optical coherence tomography (OCT) representation of the ellipsoid zone.

Methods: Customized macular OCT scans of 9 patients (10 eyes) with branch retinal vein occlusion and macular ischemia were exported and subsequently postprocessed (removal of vascular and cystic spaces' shadows, segmentation, and alignment to the retinal pigment epithelium). The ellipsoid band was then isolated, aligned, and used to produce an en face OCT image.

Purpose: To evaluate the differences in the development of collateral vessels in patients with macular edema due to branch retinal vein occlusion (BRVO) after treatment with either grid laser or ranibizumab (RNB).

Methods: Comparative study including patients with macular edema due to acute BRVO and best-corrected visual acuity (BCVA) between 20/40 and 20/200. The sample was divided into two groups according to the treatment applied: laser group, including eyes treated with Argon laser when retinal hemorrhages were sufficiently absorbed to perform the treatment, and RNB group, including patients treated initially with one monthly intravitreal injection for a period of 3 months of RNB and more injections according to need thereafter.

Purpose: To evaluate the efficacy and safety of fluorescein angiography (FA)-guided photodynamic therapy (PDT) for the treatment of severe chronic central serous chorioretinopathy (CSC).

Methods: Patients presenting with chronic CSC with multiple areas of retinal pigment epithelium decompensation, with or without focal leaks, were treated with FA-guided full-fluence PDT. Best-corrected visual acuity (BCVA), optical coherence tomography (OCT), FA, indocyanine green angiography, and fundus autofluorescence were used to determine functional and anatomic outcomes.

Background: To compare the efficacy of thermal laser photocoagulation versus intravitreal ranibizumab for the treatment of extrafoveal classic choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).

Methods: We conducted a retrospective study on 24 eyes with extrafoveal classic CNV secondary to AMD, treated either with thermal laser photocoagulation (group 1) or with intravitreal ranibizumab (group 2). Visual acuity, number of injections/sessions and recurrence rate were assessed.

Purpose: To evaluate the efficacy of intravitreal ranibizumab in eyes with exudative age-related macular degeneration associated with retinal pigment epithelial tear.

Methods: In this retrospective case series, patients with active exudative age-related macular degeneration associated with retinal pigment epithelial tear were treated by repeated injections of intravitreal ranibizumab. The outcome measures were best-corrected visual acuity and the signs of lesion activity, as evaluated by optical coherence tomography, fluorescein angiography, and indocyanine green angiography.

Background: To report the rare association of peripheral retinal ischemia in a patient with Waldenström's macroglobulinemia.

Case Presentation: A 39-year old man with a recent diagnosis of asymptomatic Waldenström's macroglobulinemia (WM) was referred from his physician for ocular evaluation. The fundus examination in his right eye (RE) revealed very mild central vein dilation, while retinal hemorrhages associated with microaneurismal alterations of the vascular plexus were detected at the temporal periphery.

Background: To evaluate the efficacy of intravitreal injections of ranibizumab in patients with diabetic clinically significant macular edema (CSME), when further focal or grid laser was considered to be unsafe.

Methods: In this retrospective, interventional case study, intravitreal injections of ranibizumab were performed in 16 eyes (ten patients) suffering from diabetic retinopathy with CSME. All patients had been treated in the past with focal or grid laser.

Purpose: The purpose of this study was to evaluate the efficacy of intravitreal ranibizumab in eyes with macular choroidal neovascularization secondary to angioid streaks.

Methods: A prospective interventional case series was conducted on eyes with macular choroidal neovascularization, secondary to angioid streaks, treated by repeated injections of intravitreal ranibizumab (0.5 mg) and completing a follow-up time of 1 year.

Purpose: To compare the utility of fluorescein angiography (FA) and optical coherence tomography (OCT) as diagnostic adjuncts in evaluating symptomatic patients with choroidal neovascularisation (CNV) due to multifocal choroiditis (MFC).

Methods: Patients with CNV due to MFC were retrospectively evaluated in a consecutive fashion. Fundus photography, FA, OCT and biomicroscopy were used to establish the diagnosis.

Recent studies have shown the beneficial effect of intravitreal injections of Bevacizicumab in several ocular neovasular disorders, however, the possible adverse effects of this treatment have not been fully described. The authors report the development of a full thickness macular hole (FTMH) in a 44-year-old patient with cystoid macular edema secondary to central retinal vein occlusion after treatment with intravitreal injection of Bevacizicumab and describe its course after vitrectomy, internal limiting membrane peeling and gas tamponade.
