COMPARISON OF BIORETINOMETRIC INDICATORS OF OPTIC NERVE HEAD AND RETINAL NERVE FIBER LAYER THICKNESS IN HEALTHY, OCULAR HYPERTENSION AND NORMAL TENSION GLAUCOMA EYES

Xülasə

Purpose – to assess and compare optic nerve head and retinal nerve fiber layer thickness measurements in healthy, ocular hypertension (OHT) and normal tension glaucoma (NTG) subjects using OCT.

Material and methods
The study included a total retrospectively (195 eyes) 98 participants from to 16 to 71 age of the same Azerbaijan ethnicity. I – control group, 25 healthy persons (50 eyes) 16-71 years old (52.2±3.0); II group – 40 persons with normal tension glaucoma (80 eyes) 30-74 years old (56.6±1.8) and III study group-33 participants (65 eyes) 14-80 years old (51.3±2.8) with ocular hypertension.

Results
The thinning of TRNFL OHT group when compared to the control: in the inferior quadrant – 8.2% (р¹˂0,01) and nasal – 9.1% (р¹˂0,05), RNFL aver – 6.4% (р¹˂0,01), I max – 6.4% (р¹˂0,05) and to the NTG group: the inferior – 8.7% (р²˂0,05) and superior quadrants – 8.3 (р²˂0,05); RNFL aver – 6.6% (р²˂0,05), I max – 7.1% (р²˂0,05). Hourly analysis of OHT group when compared to the control showed the thinning of TRNFL at the superior quadrant clock: 1:00 by 19.4%; nasal: 4:00 – 13.2% (р¹˂0,01) and at 5:00 of the inferior quadrant – 11.7% (р¹˂0,01). And comparing with the NTG group at the superior quadrant clock: 12:00 – 12.1% (р²˂0,01), inferior 5:00 – 11.0% (р²˂0,05); 6:00 – 10.2% (р²˂0,05). The bioretinometric indicators of ONH, when compared to the control, was a 38.6% increase in the cup area (р¹˂0,01), cup/disk area ratio – 25.1% (р¹˂0,05); II group: vert inteq rim area (vol) a 31,2% increase (р²˂0,05).

Conclusion
A significant difference in the group's OHT was revealed in the quadrantly, hourly study of TRNFL and bioretinometric parameters. No gender differences were found.
