PURPOSE: To determine the size of the superficial foveal avascular zone (FAZ) by optical coherence tomography angiography before and after surgery for an idiopathic macular hole. METHODS: A retrospective, observational case series, in which 16 eyes of 16 patients with an idiopathic macular hole were studied. Pars plana vitrectomy was performed with internal limiting membrane peeling. The foveal retinal vasculature was examined by optical coherence tomography angiography, and the area of the superficial FAZ was determined before, and at 1 and 3 months after the surgery...

Three patients with a history of previous pars-plana vitrectomy, 2 of them with perfluoropropane, and 1 with sulfur hexafluoride used, experienced eyelid swelling and pain after travelling to a higher altitude city. Gas was found in the orbit and periocular tissues, causing orbital compartment syndrome in 2 of the patients. The gas persisted on these patients despite surgical intervention, so hyperbaric oxygen therapy was advised. One patient refused, the other patient responded well to this therapy and the gas disappeared...

PURPOSE: Posterior hyaloid removal during pars plana vitrectomy and lensectomy for ectopia lentis is commonly performed, but may increase the risk of intraoperative retinal breaks and postoperative retinal detachment. This study evaluated outcomes after pars plana vitrectomy and lensectomy with or without posterior hyaloid removal. METHODS: This retrospective observational cohort study included ectopia lentis cases that underwent pars plana vitrectomy and lensectomy (2005-2014), with or without intraoperative induction of a posterior vitreous detachment (PVD)...

PURPOSE: Traditionally acceptable methods of anesthesia for vitrectomy surgery are quite varied. However, each of these methods has its own potential for complications that can range from minor to severe. The surgery procedure of vitrectomy for symptomatic vitreous floaters is much simpler, mainly reflecting in the nonuse of sclera indentation, photocoagulation, and the apparently short surgery duration. The use of 27-gauge cannulae makes the puncture of the sclera minimally invasive...

Hemoptysis is a common complication of pulmonary tuberculosis. Most of the cases of hemoptysis originate from hypertrophied bronchial arteries. Also, diabetes induces pulmonary vascular abnormalities such as endothelial dysfunction, inflammatory infiltration and pulmonary vascular remodeling. A 27-year-old male, with diabetes and a history of tuberculosis, underwent the procedure of pars plana vitrectomy under general anesthesia. After an uneventful intra-operative period, he had hemoptysis prior to extubation...

We report on the closure of a chronic posttraumatic giant macular hole. The patient presented with decreased vision in the left eye following blunt trauma 20 years prior. His dilated fundus examination revealed a 3000 um base-diameter full thickness macular hole. Surgical repair was performed with pars plana vitrectomy (PPV), internal limiting membrane peeling and autologous platelet concentrate (APC) injected over the macular hole. At one month follow-up, the macular hole had closed on exam and optical coherence tomography (OCT), and the patient reported subjective visual improvement...
