What is an OCT scan used for?
Optical Coherence Tomography (OCT) is a non-invasive diagnostic instrument used for imaging the retina. It is the technology for the future because it can enhance patient care. It has the ability to detect problems in the eye prior to any symptoms being present in the patient.
What causes macular dystrophy?
The Main Cause Of This Eye Disease Macular dystrophy is mainly associated with genetic mutations, unlike other eye diseases that can be the result of age, medication, or other reasons. The mutation of the genes can slowly breakdown the retinal cells and cause macular dystrophy.
Why is macular sparing?
Causes. The favored explanation for why the center visual field is preserved after large hemispheric lesions is that the macular regions of the cortex have a double vascular supply from the middle cerebral artery (MCA) and the posterior cerebral artery (PCA).
Is macula temporal or nasal?
The macula is a circular area of diameter 5.5 mm with a center located 17 degrees, or 4.0-5.0 mm, temporal, and 0.53 – 0.8mm inferior to the center of the optic disc. The normal central retinal artery (black arrow) is located nasal to the central retinal vein (green arrow) in the optic disc.
What is CCT test for eyes?
Abbreviations: OHT, ocular hypertension; POAG, primary open angle glaucoma; CCT, central corneal thickness. To evaluate central corneal thickness (CCT) in a black Cameroonian population of ocular hypertensive and glaucomatous subjects.
What is pneumatic retinopathy?
Pneumatic retinopexy is a procedure to repair a detached retina and restore vision. Unlike other procedures to treat a detached retina, it often takes place in an office setting. The retina is a layer of cells at the back of your eye. These cells use light to send visual information to your brain.
How is macular dystrophy treated?
There is no cure or known treatment to stop the progression of adult-onset vitelliform macular dystrophy. Management usually includes a comprehensive eye examination once or twice a year to monitor progression of the disease and for complications such as choroidal neovascularization ( CNV ).
What is another name for the macula in the eye?
For other uses of the term macula, see Macula (disambiguation). For Yellow Spot Irish whiskey, see Green Spot (whiskey). The macula sits near the centre of the retina of the human eye. The macula (/ˈmakjʊlə/) or macula lutea is an oval-shaped pigmented area near the center of the retina of the human eye and some other animalian eyes.
Why is the macula important for fine detail?
The fine detail we see is made possible by the macula. Because it is responsible for our central vision, diseases involving the macula, such as macular degeneration, cause loss of central vision. Damage to the macula results in the loss of the ability to see objects clearly in the center of vision.
What does PIL stand for in optical coherence tomography?
Spectral domain optical coherence tomography images revealed retinal pigment epithelium thinning and photoreceptor integrity line (PIL) thinning in each eye. The PIL was nonexistent temporally in each eye. The fovea was spared in each eye with normal retinal thickness of 256 microns in the right eye and 228 microns in the left eye.
What is the clinical significance of macular hole?
Clinical significance. The progressive destruction of the macula is a disease known as macular degeneration and can sometimes lead to the creation of a macular hole. Macular holes are rarely caused by trauma, but if a severe blow is delivered it can burst the blood vessels going to the macula, destroying it.
