Left
optic disc edema and hyperemia drastically decreased together with a marked reduction of the juxtapapillary retinochoroiditis.
Oedema, optic neuropathy and
optic disc pallor in later stages.
Many risk factors for NAION have been reported, such as old age, crowded
optic discs, hypertension, hyperlipidemia, diabetes mellitus, hypercoagulability, and protein S.
Both nocturnal raptors showed the highest RGC density in the ventral retinal field: while in the tawny owl, the RGC density was at the level of the ora serrata (level 1), and in the little owl it was at the level of the
optic disc (level 3).
The aim of this study was to utilize the FoDi software to investigate interindividual differences in the angle between the axis connecting the fovea center and
optic disc center and the horizontal meridian through the OHN center among patients with suspected or diagnosed glaucoma.
RNFL thickness was measured by scanning three consecutive 360 [degrees] circular scans with a diameter of 3.4 mm centered on the
optic disc. Mean RNFL thickness and average RNFL thickness in four quadrants (superior, nasal, inferior, and temporal) were calculated automatically.
Radial optic neutotomy for pars plana
optic disc surgery for central retinal vein occulusion.
Polymorphism rs7916697 in ATOH7 was reported to be an important genetic determinant of
optic disc size in a meta-analysis consisting of UK and Australian cohort (p=1.3x[10.sup.-10]) that explained 1.7% variation in the
optic disc area in the UK cohort [6], implicating its pathophysiological role in POAG.
Li and Chutatape [5] presented an algorithm that uses the clustering of image according to the bright pixel and the candidate regions are passed through principal component analysis (PCA) in order to locate the center of
optic disc region.
Recently, many
optic disc detection studies have been presented.
Doctors can classify and check
optic disc types using these features along with their contribution values and not just by reading the color fundus images.
Using dedicated software, RNFL thickness was automatically measured at a diameter of 3.45 mm around the center of the
optic disc. A total of 775 A-scans were obtained at this circumference.
