Abstract Details

Purpose:

To investigate the correlation between visual field (VF) sensitivity and retinal nerve fiber layer (RNFL) thickness, as measured by spectral domain OCT in primary open angle glaucoma patients

Setting:

Ophthalmology Outpatient Clinic, Suez Canal University Hospitals, Ismailia, Egypt

Methods:

A Cross-sectional study including 84 eyes of 42 POAG patients, controlled under medical treatment within period of 6 months were evaluated in Ophthlamology Department, Suez Canal University Hospitals, Ismailia, Egypt. The relationship between RNFL thickness measured by Optical Coherence Tomography , Topcon 3D OCT-2000 Series and VF sensitivity, expressed as mean deviation (MD) and pattern deviation (PD) measured by Optopol Technology pts 1000 Standard Automated Perimetry were evaluated

Results:

There was a strong correlation between MD of visual field & Average Thickness of NFL of OCT where any decrease in the thickness of the nerve fiber layer corresponds to decrease in the MD parameters. Otherwise, There is a correlation between PD of visual field & Average Thickness of NFL of OCT where any decrease in the thickness of the nerve fiber layer corresponds to increase in the PD parameters

Conclusions:

Our cross-sectional study has shown that the correlation between detectable structural and functional damage and change in early glaucoma is at best modest. It is important to include both structural and functional examinations for assessment of glaucoma at each stage of the disease
