A lobectomy is the surgical removal of one of the five lung lobes (right upper, right middle, right lower, left upper and left lower lobes). [24] Lobectomies are the most common type of lung surgery and the standard operation for most NSCLC patients. [25] Though specific surgical techniques vary for each lobe, the general workflow is identical.
A pulmonary laceration can cause air to leak out of the lacerated lung [10] and into the pleural space, if the laceration goes through to it. [8] Pulmonary laceration invariably results in pneumothorax (due to torn airways ), hemothorax (due to torn blood vessels ), or a hemopneumothorax (with both blood and air in the chest cavity).

The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
Pneumothorax occurs when there is air trapped between the lung and the chest wall; this can leave the patient's lung unable to fully inflate ("collapsed lung"). A bronchopleural fistula is when there is a tube-like opening that allows air to escape. [9] Minimally invasive surgery is beneficial for patient outcome, with reduced risk of ...
Far-sighted vision on left, normal vision on right Human eye cross-section A diagnosis of far-sightedness is made by utilizing either a retinoscope or an automated refractor-objective refraction; or trial lenses in a trial frame or a phoropter to obtain a subjective examination.
Symptoms include eye pain, eye redness, floaters and blurred vision, and ophthalmic examination may show dilated ciliary blood vessels and the presence of cells in the anterior chamber. Uveitis may arise spontaneously, have a genetic component, or be associated with an autoimmune disease or infection .
Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
[14] [15] It most commonly infects the nose, sinuses, eyes and brain resulting in a runny nose, one-sided facial swelling and pain, headache, fever, blurred vision, bulging or displacement of the eye (proptosis), and tissue death. [1] [6] Other forms of disease may infect the lungs, stomach and intestines, and skin. [6] The fatality rate is ...
