Exophthalamos of the left eye due to voluminous orbital cancer
Partial atrophy of the ocular muscles, partial sight still present in left eye. Right eye still functional. Cancer originated from superior levator muscle and grew back into other muscular tissues of the orbit. 
This kind of cancer is much more common in adults than in children, who tend to get retinoblastomas (in the ocular nerve) more than anything.

Deformation of kidneys following obstruction of left ureter.
The atrophy of the left kidney would only have been caused if the obstruction of the ureter was a chronic condition. An acute obstruction would have most likely caused a condition called “hydronephrosis” - the swelling of a kidney due to backup of urine.
Long-term swelling can cause permanent kidney damage (such as atrophy), but if it only affects one kidney, the body can generally function without severe complications.
