CONTROVERSIES IN THE ROLE OF PARAPAPILLARY ATROPHY IN GLAUCOMA
Parapapillary atrophy (PPA) is a condition seen in around 70% of normal individuals. Classically divided into zone alpha and beta, recently, it has been further categorized into zone gamma and delta.

Some of these zones of parapapillary atrophy are more prevalent and larger in size in glaucoma patients.
Studies have also found the rate of progression of glaucomatous change to be faster in patients with this anomaly.
This condition is of clinical significance in glaucoma suspects, as it could be another pointer indicating potential risk of converting to glaucoma.
On the contrary, there are other studies which question the relevance of these clinical features in glaucoma patients. In the light of these conflicting reports, it becomes an interesting exercise to explore this controversial area further.
A review on the controversy of the role played by PPA in glaucoma diagnosis and management is being presented by Dr Shoeb and my colleagues from the Ajmal Khan Tibbiya College, AMU, Aligarh, India. The article is available ahead of print at the following link to the Taiwan Journal of Ophthalmology.
