Following a series of inconclusive tests, experts at the institute's R.P. Eye Centre today conducted the Magnetic Resonance Imaging (MRI) scan of his eye to evaluate the extent of damage to the innermost structure.

``The further course of action will be decided only after the report comes in after four days,'' doctors attending to the boy said. The broken pieces of the lens of Nitin's spectacles pierced his eye after the duster hit him.According to the 12-year-old, it was his partner Kanhaiya who was not paying attention in class and was reading a comic book under the desk while the science teacher, R. Bali, was teaching. On noticing Kanhaiya, Bali threw the duster at him without any warning, but hit Nitin instead.

Meanwhile, Nitin's family is yet to receive the much-promised help from the Delhi Health Minister, Dr Harsh Vardhan, and the school authorities.

The boy's father, Vinod Kumar, rued: ``When the incident took place, the minister visited him in hospital and assured us of every possible help. Even the authorities of Preet Public School in Preet Vihar, where Nitin is a student of Class VII, had verbally assured us that they would bear the entire cost of treatment. But the help is yet to arrive.''

The family is now finding it difficult to shell out Rs 800 every day for the treatment at the expensive private ward. Though the boy seems composed, his father insists that the incident has left deep scars on his psyche. The teacher, who has since been suspended and is currently out on bail in the assault case, could not be contacted.

The school authorities, however, maintained that he had been teaching at the school for the past 12 years and there had never been a similar complaint against him.
