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.

Therefore optic disc area contains more detailed information that can be exploited in its identification.

Localizing Optic Disc in Retinal Image Automatically with Entropy Based Algorithm

Seed point was implanted inside optic disc area: all vessels are sprawling out from optic disk, so the same pixel intensity with blood vessel was determined as seed point and we performed region growing.

OCT can be used to analyze and measure not only the peripapillary RNFL thickness [3-5] but also topographic parameters of the ONH, including the disc area, neuroretinal rim area, and the cup-to-disc ratio [6].

Influence of Disc Size on the Diagnostic Accuracy of Cirrus Spectral-Domain Optical Coherence Tomography in Glaucoma

(23,24) NAION patients have small disc area, no or minimal physiological cupping, and characteristic disc structures such as "crowded disc", in which there is an excessive number of central retinal vein branches within the disc.

The following inclusion criteria were to be met for the study purposes: 1) eyes with best corrected visual acuity 0.2 or larger; 2) eyes with a refraction error less than 5 and astigmatism less than 3 diopters; 3) history of acute NAION occurrence no more than 4 months prior to the study; 4) eyes with normal disc area (1.69-2.82 [mm.sup.2]); and 5) subjects with reliable test results of visual field and HRT II.

COMPARISON OF OPTIC NERVE HEAD MORPHOLOGY IN PATIENTS WITH PRIMARY OPEN ANGLE GLAUCOMA AND NON-ARTERITIC ANTERIOR ISCHEMIC OPTIC NEUROPATHY

Superficial and deep retinal vascular density on macular and optic disc area were calculated as previously described in literature.[sup][17] Binary images of vascular networks were created using an automated thresholding algorithm.
