Some processes can excite RNFL apoptosis. Harmful situations which can damage RNFL include high intraocular pressure, high fluctuation on phase of intraocular pressure, inflammation, vascular disease and any kind of hypoxia. Gede Pardianto (2009) reported 6 cases of RNFL thickness change after the procedures of phacoemulsification. [18]
The GDx nerve fiber analyzers measure the retinal nerve fiber layer (RNFL) thickness with a scanning laser polarimeter based on the birefringent properties of the RNFL. Measurement is obtained from a band 1.75 disc diameters concentric to the disc. It projects a polarized beam of a light into the eye.
peripapillary retinal nerve fiber layer (retinal surface height variation, thickness, asymmetry). These stereometric parameters are compared with extensive databases and thus enable the eye to be classified taking into account the individual papillae size and the patient's age.
the portion of the range of convergence that occurs in response to accommodation: Acc: Accommodation: process of changing optical power to maintain focus as distance changes Ad: Advised: Add: Addition AIT: After-image transfer ALT: Alternating ALT ET/SOT: Alternating esotropia: ALT XT/XOT: Alternating exotropia ARC: Anomalous retinal ...
Scanning laser ophthalmoscopy developed as a method to view a distinct layer of the living eye at the microscopic level. The use of confocal methods to diminish extra light by focusing detected light through a small pinhole made possible the imaging of individual layers of the retina with greater distinction than ever before.

Optical coherence tomogram of a fingertip. It is possible to observe the sweat glands, having "corkscrew appearance" Interferometric reflectometry of biological tissue, especially of the human eye using short-coherence-length light (also referred to as partially-coherent, low-coherence, or broadband, broad-spectrum, or white light) was investigated in parallel by multiple groups worldwide ...
Asymmetry in thickness of RNFL as indicator of optic neuritis in MS [ edit ] Asymmetry between the eyes in thickness of RNFL has been proposed as a strong indicator of optic neuritis in MS. [ 92 ] [ 93 ] [ 94 ] RNFL data may indicate the pace of future development of the MS. [ 95 ] [ 96 ]
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
