Retrospective case series of high-density silicone oil (Oxane HD) in severe proliferative vitreorretinal retinal detachment patients.

Background: Describe complications and clinical outcomes of heavy silicone oil (HSO) Oxane HD® use as an alternative to overcome the challenges of performing vitrectomy to treat tractional and rhegmatogenous retinal detachments with proliferative vitreoretinopathy (PVR).

Methods: A retrospective, observational study was performed on patients from one center from August 2014 to Aug 2023. It was included patients who underwent surgery using HSO Oxane HD® to treat rhegmatogenous retinal detachment with PVR or mixed tractional and rhegmatogenous diabetic retinal detachment.

Surgical technique for removal of high-density silicone oil (Oxane HD).

The main drawback for the use of heavy silicone oil (HSO) Oxane HD is the difficulties it presents during removal. It differs from conventional silicone oil removal because it progressively concentrates in the posterior pole during the removal because of its heavier than water density. We describe a technique to facilitate proper HSO Oxane HD removal and minimize residual posterior bubbles and intraoperative complications.

Bartonella hanselae retinitis patient evaluated with multimodal retinal exams.

Background: Cat scratch disease is a systemic infectious illness caused by the bacterium Bartonella henselae. The most common ophthalmological involvement due to infection by Bartonella is Parinaud oculoglandular syndrome, whereas the most common posterior segment findings are neuroretinitis and subsequent late macular star. Moreover, other findings, such as retinal or subretinal lesions, intermediate uveitis and angiomatous lesions, may be present.

VALUE OF CLINICAL, LABORATORY PARAMETERS AND ANALYSIS OF RETINAL VASCULARIZATION IN PEDIATRIC PATIENTS WITH PORTAL HYPERTENSION.

Background: Portal hypertension is one of the complications of cirrhosis and is associated with numerous systemic manifestations, including renal, brain, pulmonary, cardiac and vascular changes. In routine ophthalmological examinations performed at our service, we observed that some children diagnosed with portal hypertension had increased retinal vascular tortuosity.

Objective: 1.

PURTSCHER-LIKE RETINOPATHY AND PARACENTRAL ACUTE MIDDLE MACULOPATHY CAUSED BY INDUSTRIAL SILICONE EMBOLISM.

Purpose: This article describes a rare occurrence of acute vision loss in a healthy young patient after a cosmetic procedure.

Methods: Findings on clinical examination, color fundus photography, and swept-source optical coherence tomography angiography.

Results: A previously healthy 26-year-old male-to-female transsexual presented with dyspnea, fever, and hypoxemia 1 day after cosmetic injection of industrial silicone for buttock augmentation.

Six-year epidemiological analysis of post traumatic endophthalmitis in a Brazilian hospital.

Background: To evaluate the epidemiology of endophthalmitis cases related to ocular trauma, including visual acuity during and 1 year after trauma, source of trauma and method of treatment.

Methods: A retrospective study analyzed the epidemiological data of patients with a clinical presentation of endophthalmitis after ocular penetrating trauma between January 2012 and January 2017 at Escola Paulista de Medicina/UNIFESP, a hospital in São Paulo, SP, Brazil.

Results: A total of 453 patients with antecedent open globe trauma were evaluated, among these, 30 patients with suspected endophthalmitis.

The retinal foveal avascular zone as a systemic biomarker to evaluate inflammatory bowel disease control.

Background: Inflammatory bowel disease (IBD) is a systemic inflammatory disease and is classified as Crohn's disease (CD) or ulcerative colitis (UC) depending on the extent of gastrointestinal tract involvement. IBD can be associated with extraintestinal findings, such as fever, weight loss, arthralgia, and mucocutaneous lesions, as well as hepatic, renal and ophthalmological involvement. Clinical parameters and colonoscopy are used to establish the criteria for controlled or non-controlled disease and subsequent definition of treatment.

FREQUENCY OF OPHTHALMOLOGICAL POSTERIOR SEGMENT FINDINGS IN PATIENTS WITH INFLAMMATORY BOWEL DISEASE.

Background: Inflammatory bowel disease is a systemic inflammatory disease classified as Crohn disease or ulcerative colitis. It could present extra intestinal findings, such as fever, weight loss, arthralgia, mucocutaneous lesions, hepatic, renal and ophthalmological involvement. Among ophthalmological findings, posterior segment findings are present in less than 1% of patients with inflammatory bowel disease, however, these findings could bring definitive visual impairment.

Aqueous misdirection syndrome in persistent fetal vasculature (PFV).

We report a case of a 5-year-old girl with persistent fetal vasculature who presented with unilateral acute angle closure caused by aqueous misdirection syndrome that was apparently associated with regression of cycloplegia. Initial treatment with topical steroids, anti-glaucomatous drops, and atropine showed insufficient control of the intraocular pressure (IOP). Surgical treatment with lensectomy and vitrectomy resulted in satisfactory IOP control and no complications at the 6-month follow-up.
