![]() ![]() ![]() Your surgeon may instruct you to use antibiotic eye drops following the surgery. If the gas bubble were to rest against the lens of the eye, a cataract or high pressure within the eye may form. THE PATIENT MUST ALSO TAKE CARE NOT TO LIE IN THE FACE-UP (SUPINE) POSITION. High altitudes can cause the gas bubble to expand, increasing the pressure within the eye, which can lead to severe eye damage. The gas bubble in the vitreous cavity of the eye expands for several days and takes two to six weeks to disappear completely.ĭuring this time, the patient must AVOID AIRPLANE TRAVEL OR TRAVEL TO HIGH ALTITUDES. It is crucial for the success of the procedure that the patient maintains a specific position of their head (for several days up to a week) as instructed by their surgeon so that the retinal tear can be effectively sealed by the gas bubble pushing on the retina inside the eye. Using a needle, the surgeon then injects a gas bubble inside the vitreous cavity of the eye. The retinal tear is sealed with cryotherapy. Pneumatic retinopexy is effective only for superior retinal detachments and tears. Pneumatic retinopexy is performed under local anesthesia in our office as an outpatient procedure.Īn alternative to scleral buckling surgery, which is performed in an operating room, pneumatic retinopexy requires no hospitalization, general anesthesia, or cutting of the eye. Pneumatic retinopexy is an in-office procedure that can be performed to correct selected retinal detachments. Laser, or “hot” treatment to the retina, uses different wavelengths of light to seal leaking blood vessels (diabetes or wet macular degeneration) or to induce a biologic pigment seal around retinal tears that can be visualized through a special lens applied to the eye. Usually, patients often require local anesthesia before the cryotherapy and eye drops and an eyepatch following surgery. Surgeons often prefer using cryotherapy over laser treatment when problems arise with the far outside corners of the retina, especially when the patient has a vitreous hemorrhage or cataract obscure the passage of light into the eye, limiting the effectiveness of a laser.Ĭryotherapy is often performed in conjunction with surgical treatments for retinal detachment, such as pneumatic retinopexy or scleral buckle surgery. Similar to a laser’s heat, the intense cold stimulation of the retina can seal abnormal leaky retinal blood vessels or retinal tears by stimulating a biologic pigment seal. The sclera transmits the cold inward so the freezing temperature is effectively applied to the retina. With cryotherapy, an extremely cold probe is applied to the outside of the eye, or sclera. ![]() Visual field testing can be performed clinically by keeping the subject’s gaze fixed while presenting objects at various places within their visual field. ![]() Most important for your ophthalmologist and surgeon, fluorescein angiography provides a picture of exactly where the retinal blood vessels are leaking and can thus guide laser treatment with pinpoint accuracy, as well as monitoring response to treatment.Ī Goldmann visual field test is an eye examination that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such as glaucoma, stroke, pituitary disease, brain tumors, or other neurological deficits. Diabetes, the leading cause of blindness in patients UNDER the age of 65, can cause the blood vessels of the retina to leak fluid or blood and can cause new blood vessels to grow on the retinal surface.Īge-related macular degeneration is the leading cause of blindness in patients OVER the age of 65, and it can also be detected with and monitored by fluorescein angiography. Damage to the lining underneath the retina or the appearance of abnormal new blood vessels growing beneath or on the surface of the retina may also be revealed.įluorescein angiography is useful in detecting several diseases of the retina. If the blood vessels are abnormal, the dye may leak into the retina or stain the blood vessels. The dye travels throughout the body, and as it passes through the blood vessels of the retina, a special camera flashes a blue light into the eye and takes multiple photographs. Fluorescein Angiography Fluorescein angiography is a diagnostic procedure that uses a special camera to photograph the light-sensitive retina and more specifically, the blood vessels in the back of the eye.įirst, fluorescein, a water-soluble dye, is injected into a vein in the arm. ![]()
