Abstract

AIM- To study the pattern of visual field defect and Retinal Nerve Fiber Layer thickness (RNFL) loss in Primary Angle Closure Glaucoma.

METHOD- 39 diagnosed cases of PACG underwent visual field analysis (VFA) and Optic nerve head analysis. Cases were classified into mild, moderate and severe based on Mean Deviation (MD) values. MD and RNFL thickness loss were compared and average MD of each hemifield was compared with corresponding RNFL loss. The pattern of VF defect was analyzed.

RESULTS- The most common type of VF defects in the mild and moderate groups was an arcuate field defect, whereas in severe PACG cases it was an advance field defect. Superior hemifield had worse MDs in mild and moderate cases. Both hemifields were equally affected in severe cases with corresponding RNFL loss.

CONCLUSION- In our study, superior hemifield was affected more in mild and moderate cases, and both hemifields were equally affected in severe cases with corresponding loss in RNFL thickness.
