What is involved in retinal cryopexy in the case of retinal detachment?
irritating the tissue around each of the retinal tears. Cryopexy stimulates scar formation, sealing the edges of the tear. This is typically done by looking into the eye using the indirect ophthalmoscope
What is retinal cryopexy?
a procedure that uses intense cold to induce a chorioretinal scar and to destroy retinal or choroidal tissue
What conditions is retinal cryopexy used to treat?
retinal breaks or detachments; retinal ischemia (retinal tissue that lacks oxygen); neovascularization (proliferation of blood vessels in the retina); Coats' disease
What is the likelihood of success in retinal cryopexy?
For retinal reattachments, the retina can be repaired in about 90% of cases. Early treatment almost always improves the vision of most patients with retinal detachment.
What risks are associated with retinal cryopexy?
infection, perforation of the eye with the anesthetic needle, bleeding, double vision, and glaucoma.
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.
How may laser photocoagulation serve as an alternative to retinal cryopexy?
by destroying outer retinal tissue, thus reducing the oxygen requirements of the retina, and increasing oxygen delivery to the remaining retina through alterations in oxygen diffusion from the choroid.
What does cryopexy entail?
Cryopexy is a medical procedure used to treat retinal detachment. It involves applying freezing temperatures to create a scar that seals a retinal tear or hole, helping to reattach the retina to the back of the eye. This procedure is typically done in a doctor's office or outpatient setting using a specialized instrument.
What aftercare is prescribed for patients of joint replacement?
the patient will be catheterized so that he or she will not have to get out of bed to urinate. The patient will be monitored for infection. Antibiotics are continued and pain medication is prescribed.
What measures are prescribed as aftercare for trabeculectomy patients?
Antibiotic and anti-inflammatory eye drops must be used for at least six weeks after surgery. Additional medicines may be prescribed to reduce scarring.
What aftercare is prescribed for tube enterostomy?
Tube enterostomy requires monitoring the patient for infection or bleeding, and educating him or her on the proper use of the enterostomy
What aftercare is prescribed for sclerostomy patients?
They should apply eye drops prescribed by the ophthalmologist to prevent infection, manage pain, and reduce swelling. They should also avoid rubbing, bumping, or getting water into the operated eye.
