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. [4]
Fundus photographs are also used to document abnormalities of disease process affecting the eye, and/or to follow up on the progress of the eye condition/disease such as diabetes, age-macular degeneration (AMD), glaucoma, multiple sclerosis, and neoplasm of the choroid, cranial nerves, retinal or eyeball.
Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes.Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).
The analyser will provide a lens strength and type (either spherical and/or cylindrical), if required for the test. In these instances, wire-rimmed trial lenses are generally used, with the cylindrical lens placed closest to the patient so the axis is easily read. The clinician can alter the fixation targets as per necessary (see Fixation ...
Photostress recovery time measurement procedure is known as photostress test. Normal recovery time is about 15–30 seconds. [1] The photostress test is a simple, easy and quick clinical technique that can differentiate between retinal and postretinal (e.g.optic nerve) disease. [2]
DxO ViewPoint's corrections are based on DxO's data created through a large volume of images produced using different lens and camera combinations in DxO's laboratory. [ 1 ] DxO ViewPoint's volume distortion correction can be used to attempt to recover the natural proportions of objects that have been distorted due to their proximity to the ...
Age-related macular degeneration: A common cause of central vision loss; early diagnosis via ophthalmologic examination may facilitate slower disease progression. The examiner will evaluate the macula for deposits of cellular debris called drusen , in particular their size, number, and distribution, as well as pigmentary changes, atrophy, and ...
Recently, central serous chorioretinopathy has been understood to be part of the pachychoroid spectrum. [5] [6] In pachychoroid spectrum disorders, of which CSR represents stage II, the choroid, the highly vascularized layer below the retina, is thickened and congested with increased blood vessel diameter, especially in the deep choroid (the so-called Haller's layer).
