They point out that upon the petitioners repatriation, he was immediately referred to an ophthalmologist who scheduled him for observation and regular monitoring preparatory to possible vitrectomy. He was prescribed medication in the meantime.   On November 13, 2000, the petitioner underwent laser treatment of the right eye, which he tolerated well. His vitrectomy, scheduled on November 22, 2000, was deferred because he was noted to have accentuated bronchovascular marking on his chest x-ray, and mild chronic obstructive pulmonary disease as revealed by his pulmonary function test.
