Introduction: Valsalva retinopathy is a unilateral or bilateral condition that occurs when increased intra-thoracic or intra-abdominal pressure transmitted to the eye causes a sharp rise in the intraocular venous pressure, and rupture of superficial retinal capillaries. The patient often gives a history of a recent strenuous physical act, which could have increased the intra-thoracic pressure. ...

PURPOSE Ablating and cutting vitreoretinal membranes using a 193-nm excimer laser-based microsurgical system. METHODS A 193-nm microsurgical system enables delivery of the beam into a fluid medium to cut preretinal and subretinal membranes. Two patients with proliferative diabetic retinopathy and one patient with proliferative vitreoretinopathy were treated with this new device. RESULTS Gen...

PURPOSE. Light microscopic and ultrastructural studies were perfomed in the human epiretinal membranes secondary to proliferative vitreoretinopathy (PVR).HETRODS.Humanpreretinal membranes from 5 eyes with PVR were obtained by vitrectomy. These membranes were processed for inmunohistochemical (GFAP) and electron microscopy studies to study the morphology and the cell composition. RESULTS. Light ...

We report a case of complete surgical resolution of Valsalva retinopathy that manifested as a premacular hemorrhage involving a membrane followed by a macular hole (MH) resulting from the first vitrectomy. A 20-year-old female patient was referred to our hospital due to sudden vision loss in the left eye. Her best-corrected visual acuity (BCVA) in the left eye was hand motion. Fundus photograph...

Parafalcine subdural hemorrhage was first described by Arring and Evans in 1940 as an atypical localization. On the other hand, it has become more recognized due to widespread availability of computed tomography since that day. Hemorrhages parafalcine region constitute 9-15% all blunt trauma-induced intracranial hemorrhages. Although small amounts hemorrhages are benign, mortality is high with ...
