The eye is a fragile organ, and requires extreme care before, during, and after a surgical procedure. An eye surgeon is responsible for selecting the appropriate surgical procedure for the patient and for taking the necessary safety precautions.
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...
Physical examination and accessing the history and physical examination is focused on sites of infection. Indwelling line sites, areas of skin breakdown, sinuses, nasopharynx, bronchi and lungs, alimentary tract, and skin are assessed. [31] The diagnosis of neutropenia is done via the low neutrophil count detection on a complete blood count ...
Trabeculectomy is a surgical procedure used in the treatment of glaucoma to relieve intraocular pressure by removing part of the eye's trabecular meshwork and adjacent structures. It is the most common glaucoma surgery performed and allows drainage of aqueous humor from within the eye to underneath the conjunctiva where it is absorbed.
In this procedure aqueous humor from the anterior chamber of eyeball is drained out by using a tuberculin syringe, with or without a plunger attached to a hypodermic needle or a paracentesis incision. [1] Eye is anesthetized using proparacaine or tetracaine eye drops prior to ACP. [5] Paracentesis is performed through the clear cornea adjacent ...
An eye examination, commonly known as an eye test, [1] is a series of tests performed to assess vision and ability to focus on and discern objects. [2] It also includes other tests and examinations of the eyes. [2] Eye examinations are primarily performed by an optometrist, ophthalmologist, or an orthoptist.
The operation may occur on a stretcher or a reclining examination chair. The eyelids and surrounding skin are swabbed with a disinfectant, such as 10% povidone-iodine, and topical povidone-iodine is put in the eye. The face is covered with a cloth or sheet with an opening for the operative eye.
The pupil is a hole through which the eye's interior can be viewed. For better viewing, the pupil can be opened wider (dilated; mydriasis) before ophthalmoscopy using medicated eye drops (dilated fundus examination). However, undilated examination is more convenient (albeit not as comprehensive), and is the most common type in primary care.
