Case Report: Complete tomographic resolution of focal choroidal excavation complicated with choroidal neovascularization after anti-VEGF treatment.

Purpose We report a case of focal choroidal excavation (FCE) that resolved after intravitreal injection of anti-vascular endothelial growth factor (VEGF) for choroidal neovascularization (CNV) and we describe its tomographic features. Case report A 43-year-old female presented with blurred vision and metamorphopsia in her left eye (LE) evolving for 10 years. The best corrected visual acuity (BCVA) was 20/20 in the right eye and 20/32 in the LE.

Peripapillary retinal neovascularization and vitreous hemorrhage secondary to peripapillary pachychoroid syndrome.

Purpose: To report a case of peripapillary pachychoroid syndrome (PPS) complicated with peripapillary retinal neovascularization causing vitreous hemorrhage.

Observation: A 42-year-old man, with a history of a visual loss of the right eye (RE) for 4 years, presented for ophthalmological examination. Best-corrected visual acuity was «counting fingers» in the RE and 20/25 in the left eye.

Attitudes and prevention towards malaria in the context of COVID-19 pandemic in urban community in Benin, West Africa.

Background: The COVID-19 pandemic and its damages have severely impacted the global healthcare system even in countries with the best systems. In sub-Saharan Africa (SSA), it could worsen the malaria situation in endemic countries such as Benin. This study was conducted to describe the potential effects of the pandemic on urban dwellers attitudes, prevention and treatment against malaria in four major cities of Benin.

Optical coherence tomography angiography analysis of microvascular abnormalities and vessel density in treatment-naïve eyes with diabetic macular edema.

Background: The aim of this study was to evaluate the structural retinal vascular integrity using optical coherence tomography angiography (OCTA) in treatment-naïve eyes with diabetic macular edema (DME) and to compare it with findings in diabetic eyes without DME.

Methods: In this prospective study, 70 eyes with diabetic retinopathy were included (37 eyes with DME and 33 eyes without DME). The medical records, including swept-source optical coherence tomography and 9 × 9 mm swept-source OCTA images were reviewed and compared between DME and non-DME groups.

Management of trauma White weapons penetrating Head and Neck in the anesthesia department of the national hospital of Zinder in Niger: About five reported cases.

We report five cases of craniocervical trauma with knives. The occurrence circumstances were common to all injuries. The trauma was caused by a knife during a fight or an intentional injury.

Evaluation of the effect of the severity of diabetic retinopathy on microvascular abnormalities and vascular density using optical coherence tomography angiography.

Purpose: To quantify and to study the relationship between retinal microvascular changes and different stages of diabetic retinopathy (DR) using optical coherence tomography angiography (OCTA).

Methods: This prospective observational study included the eyes of patients with different stages of DR. OCTA was performed in all eyes using a 9 × 9 mm protocol.

Bilateral diffuse uveal melanocytic proliferation: Report of a rare Ocular Paraneoplastic Syndrome.

Bilateral diffuse uveal melanocytic proliferation is a rare paraneoplastic disorder where bilateral blindness is caused by uveal thickening, serous retinal detachment, and rapid cataract formation. Several different malignancies have been associated with bilateral diffuse uveal melanocytic proliferation, but ovarian carcinoma in women and lung and pancreatic carcinoma in men are the most common. The underlying mechanism is thought to be related to a an endogenous factor wich regulates the proliferation of uveal melanocytes.

Perioperative management of gastrointestinal surgery in a resource-limited hospital in Niger: Cross-sectional study.

Background: Perioperative management in digestive surgery is a challenge in sub-Saharan Africa. Objective: To describe the process and outcomes of perioperative management in gastrointestinal surgery.

Materials And Methods: This was a single center cross-sectional study over a 4-month period from June 1 to September 30, 2017, in a Nigerien hospital (West Africa).
