Valsalva maculopathy: To treat or not to treat
To discuss diagnostic strategies and management options in cases with suspected valsalva maculopathy (VM), to optimize visual outcome. We describe six cases with suspected VM. The preretinal hemorrhage resolved spontaneously in four out of six patients, without any intervention. One patient underwent neodymium-doped yttrium aluminum garnet hyaloidotomy and the other proceeded to have a vitrecto...
متن کاملThe Valsalva Manoeuvre a Critical Review
The Valsalva manoeuvre is commonly used in diving to equalise middle ear pressures during descent. A forceful expiration with the nostrils and mouth held shut results in an increased nasopharyngeal pressure and opening of the Eustachian tubes. The correctly performed manoeuvre is easily taught, effective and usually without complications. When performed incorrectly, prolonged periods of raised ...
متن کاملInfluence of posture on the Valsalva manoeuvre.
The objective of the present study was to evaluate the influence of posture on the responses of blood pressure (BP) and heart rate (HR) to the Valsalva manoeuvre (VM). Neurohumoral activation, as well as changes in intravascular and intracardiac volumes and pressures, are well known effects of orthostatic stress. These changes are likely to have significant effects on cardiovascular reflexes, s...
متن کاملThe Valsalva manoeuvre: physiology and clinical examples.
The Valsalva manoeuvre (VM), a forced expiratory effort against a closed airway, has a wide range of applications in several medical disciplines, including diagnosing heart problems or autonomic nervous system deficiencies. The changes of the intrathoracic and intra-abdominal pressure associated with the manoeuvre result in a complex cardiovascular response with a concomitant action of several ...
متن کامل[Valsalva maculopathy in a medical employee working in the hyperbaric chamber--a case report].
We discuss the influence of increased pressure (compression and decompression in the hyperbaric chamber) on the human body, in particular the organ of vision. An extraordinary, quite rare case of painless loss of vision connected with retinal hemorrhage, followed by scarring in the person who performed the Valsalva maneuver working inside the hyperbaric chamber. The lesion was determined with h...
