Ophthalmic Imaging
Fluoroangiography: It is a special diagnostic test that uses a special camera, which takes pictures of the retina, at the bottom of the eye.
Mydriatic eye drops are instilled into the eyes, so that the pupils of the eyes are dilated.
A special solution of water and dye (fluorescein) is injected intravenously into the hand. The substance is transported through the veins to the arteries in the retina. As fluid passes through the vessels of the retina, a special camera takes pictures of the fluorescent retina.
Fluoroangiography helps the ophthalmic surgeon monitor the function of the retina and choroid, and diagnose possible lesions so that the most correct and effective treatment can be given. (Macular degeneration, diabetes, paleness, vascular diseases, etc.). What Are Some Rare, Side Effects Of Fluoroangiography?
If there is a leakage of pigment from the vein of the hand, a burning sensation will appear locally. The eyes will be photosensitive due to mydriasis. The use of sunglasses after the end of the examination is considered necessary. Vision will be blurred due to dilation eye drops temporarily, lasting about 3-4 hours. The presence of an escort is considered necessary. For a few hours after fluorescein injection, the skin color may show a slight yellow tinge. Urine stains (dark orange) for at least 24 hours after the test, as the kidneys remove fluorescein from the body. Allergic reactions to fluorescein are rare. They usually manifest in the form of a skin rash, with a strong itching sensation. Such reactions are treated with antihistamines or injections, depending on the severity of the symptoms. At the LaserVision Institute of Ophthalmology, fluoroangiographies are always performed in the presence of an anesthesiologist, in order to ensure the safety of patients, even in these rare cases.
Contraindications to fluoroangiography: Renal failure Liver failure Serious heart disease History of allergy to contrast agents Hertel eye examination: In many people, we see that the upper eyelid does not cover the upper part of the iris of the eye, and we are given the impression that this person is “rolling” the eyes. Ocular, is the abnormal projection of one or both eyes. The ocular measurement is the test with which we measure the presence or absence of the ocular. The ocular is found in diseases of the thyroid gland, but also in conditions such as bulb tumors, inflammation and vascular abnormalities. The ophthalmometer is a completely painless test, performed in a few minutes, with a special device called the Hertel Ophthalmometer. Orthopedic Study: Examines the function of the ocular muscles, and diagnoses possible strabismus and other abnormalities related to the function of the ocular muscles (eg convergence, esophagus, exophthalmos), or some neurological problems. Color perception test: It is done for the diagnosis of dyschromatopia, as well as for the quality assessment of optic nerve diseases (optic neuritis, etc.). Tear-tear layer assessment: Estimation of the quantity and quality of the tear layer. It is done mainly for contact lens users, in the preoperative examination of refractive surgeries, and in cases of dry eye, blepharitis, etc. Our scientific team has led the world in the use of 3D imaging of the corneal epithelium, as a means of assessing the lacrimal layer and dry eye.
