To investigate the correlation between optic disc parameters (disc area and vertical cup disc ratio) and peripapillary retinal nerve fiber layer thickness and its value in evaluating glaucoma cases using optical coherence tomography.this study included 35 eyes of 20 patients, 9 males and 11 females. 17 eyes as glaucoma cases and 18 control eyes (age: 51.8±10.85years old) were recruited at ophthalmology department at Benha university hospital. Finish ophthalmic assessment, visual field Also oct optic nerve imaging were completed In the examination unit of the division. Circle range (DA) qualities (M±SD) were 2. 31± 0. 34 Furthermore 2. 69±0. 51 for cases Also control separately (P value: 0. 016). VCDR values (M±SD) were 0. 67±0. 16 What's more 0. 62 ±0. 14 to instances What's more control individually (p value: 0. 28). Da indicate main noteworthy connection should nasal PPRNFL thickness same time VCDR show main critical negative correspondence on Normal PPRNFL thickness. There may be critical sure relationship between VCDR What's more da. Roc bend Investigation trying legitimacy of da Also VCDR to foresee glaucoma demonstrate helter skelter affectability (82. 4%) Also low specificity (61. 1%) to da (p esteem 0. 009) Also low affectability (58. 8%) Also low specificity (44. 4%) for VCDR (p worth 0. 85). VCDR might be a uncaring technique for assessing alternately screening glaucomatous practical harm On POAG alternately classifying its seriousness. Circle zone altogether influences VCDR Also might need a part done foreseeing POAG instances.
