What is the purpose of photocoagulation therapy?
The purpose of photocoagulation therapy is to reattach a torn or detached portion of the retina and/or prevent further growth of abnormal blood vessels in the retina that can cause a detachment.
What risks exist for the patient who has undergone photocoagulation therapy?
The most common risks of laser photocoagulation therapy are mild discomfort at the beginning of the procedure and the possibility that a second laser treatment will be needed to reattach the retina securely.
How should patients be prepared for photocoagulation therapy?
Preparation for photocoagulation therapy consists of eye drops that dilate the pupil of the eye and numb the eye itself. The laser treatment is painless, although some patients require additional anesthetic for sensitivity to the laser light.
What does laser photocoagulation accomplish?
The procedure stops leakage of abnormal blood vessels by burning them to slow the progress of the disease.
What characteristics does a successful photocoagulation therapy have?
Over 90% of retinal detachments can be repaired with prompt treatment, although sometimes a second procedure is needed. About 40% of patients treated for retinal detachment will have good vision within six months of surgery.
Laser photocoagulation treats what ocular disorder?
Laser photocoagulation is commonly used to treat diabetic retinopathy, a serious eye condition that can lead to vision loss or blindness. The procedure helps to seal leaking blood vessels and reduce abnormal blood vessel growth in the retina.
What is photocoagulation therapy?
Photocoagulation therapy is a method of treating detachments (tears) of the retina (the layer of light-sensitive cells at the back of the eye) with an argon laser. The high-intensity beam of light from the laser is converted into heat.
What is photocoagulation?
Surgical coagulation of tissue by means of intense light energy, such as a laser, performed to destroy abnormal tissues or to form http://www.answers.com/topic/adhesive scars, especially in http://www.answers.com/topic/ophthalmology
What characteristics does an abnormal fetal hemoglobin test have?
Greater than 2% of total hemoglobin is abnormal.
What is a description of how gene therapy works?
Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein.
What characteristics does an abnormal external sphincter electromyography have?
A diseased external sphincter muscle will produce an abnormal pattern of electrical activity.
What alternatives exist to photocoagulation therapy?
One alternative for the treatment of small areas of detachment is cryopexy, which is performed as an outpatient procedure under local anesthesia. In cryopexy, the ophthalmologist uses nitrous oxide to freeze the tissue underneath the retinal tear.
