Hyphema is the medical condition of bleeding in the anterior chamber of the eye between the iris and the cornea. [1] People usually first notice a loss or decrease in vision. [ 1 ] The eye may also appear to have a reddish tinge, or it may appear as a small pool of blood at the bottom of the iris in the cornea.
Hyphema, anterior uveitis and glaucoma are three main pathologies in this area. In hyphema, blood fills the anterior chamber as a result of a hemorrhage, most commonly after a blunt eye injury. Anterior uveitis is an inflammatory process affecting the iris and ciliary body, with resulting inflammatory signs in the anterior chamber.
Once an open globe has been ruled out, intraocular pressure should be checked and treated if greater than 21 mm Hg. All patients with hyphema require ophthalmology consultation. Any patient with a hyphema larger than grade II, elevated intraocular pressure, or sickle cell disease—or who is unable to comply with daily ophthalmology evaluations ...
The diagnosis of UGH Syndrome is mainly based on patient history and eye examination. Patient will have history of cataract surgery with intraocular lens implantation. Slit-lamp examination may reveal hyphaema, aqueous cells and flare, iris neovascularization, mispositioned IOL, iris-lens contact, iris transillumination defects etc. [2]
Patients are often asymptomatic and the disease is often discovered through investigation of the cause of the heterochromia or cataract. Neovascularisation (growth of new abnormal vessels) is possible and any eye surgery, such as cataract surgery, can cause bleeding from the fragile vessels in the atrophic iris causing accumulation of blood in ...
The surgeon should be seated temporally, and the patient's head tilted away by 30 degrees. The microscope should be set up by centering its head, confirming that the tilt knob is covered with a handle. The equipment is then tilted toward the surgeon by 30 degrees. The microscope should be manually lowered, bringing the limbus into focus.
Nd:YAG laser peripheral iridotomy (LPI) may be used in patients susceptible to or affected by angle closure glaucoma or pigment dispersion syndrome. During laser iridotomy, laser energy is used to make a small, full-thickness opening in the iris to equalize the pressure between the front and back of the iris, thus correcting any abnormal ...
Hypopyon is a medical condition involving inflammatory cells in the anterior chamber of the eye.. It is an exudate rich in white blood cells, seen in the anterior chamber, usually accompanied by redness of the conjunctiva and the underlying episclera.
