  2. Occult macular dystrophy - Wikipedia

    en.wikipedia.org/wiki/Occult_macular_dystrophy

    Occult macular dystrophy (OMD) is a rare inherited degradation of the retina, characterized by progressive loss of function in the most sensitive part of the central retina , the location of the highest concentration of light-sensitive cells (photoreceptors) but presenting no visible abnormality.

  3. Scanning laser ophthalmoscopy - Wikipedia

    en.wikipedia.org/wiki/Scanning_laser_ophthalmoscopy

    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 photography - Wikipedia

    en.wikipedia.org/wiki/Fundus_photography

    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.

  5. Optical coherence tomography - Wikipedia

    en.wikipedia.org/wiki/Optical_coherence_tomography

    Ocular OCT retinal thickness map, right eye Time-domain OCT of the macular area of a retina at 800 nm, axial resolution 3 μm Spectral-domain OCT macula cross-section scan. Optical coherence tomography (OCT) is a technique for obtaining sub-surface images of translucent or opaque materials at a resolution equivalent to a low-power microscope.

  6. Optical coherence tomography angiography - Wikipedia

    en.wikipedia.org/wiki/Optical_Coherence...

    A short scan time prevents too much patient movement during signal acquisition. With the development of Fourier-domain OCT, spectral-domain OCT, and swept source signal acquisition time was greatly improved making OCTA possible. [40] OCTA scan time is now around three seconds, however, saccadic eye movement still causes a low signal-to-noise ratio.

  7. Epiretinal membrane - Wikipedia

    en.wikipedia.org/wiki/Epiretinal_membrane

    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).

  8. Heidelberg Retinal Tomography - Wikipedia

    en.wikipedia.org/wiki/Heidelberg_retinal_tomography

    The Heidelberg Retinal Tomography is a diagnostic procedure used in ophthalmology. The Heidelberg Retina Tomograph (HRT) is an ophthalmological confocal point scanning laser ophthalmoscope [ 1 ] for examining the cornea and certain areas of the retina using different diagnostic modules (HRT retina, HRT cornea, HRT glaucoma).

  9. Cotton wool spots - Wikipedia

    en.wikipedia.org/wiki/Cotton_wool_spots

    Another method of diagnosis or screening is through the use of spectral domain optical coherence tomography (SD-OCT) which follows the cotton wool spots and their progression. [1] The emergence of advanced technological tools like SD-OCT are providing new insight of neurosensory retinal health in vivo , especially in cases such as analysis of ...
