“Right eye showed old tractional retinal detachment involving the macular area and left eye had perivascular sheathing.”

“I FIRST used the YAG laser in vitreous disorders in 1987 where we described the successful lysing of tractional retinal detachments in sickle cell patients.”

“If the new blood vessels are extensive, they may cause scarring inside the eye, resulting in tractional retinal detachments, which is another cause of permanent vision loss.”

“The final drives were selected for heavy-duty work cycles and a high tractive effort.”

“And because the tractor unit is self-contained in a single unit, greater tractive effort can be applied to help move the unit through wet soils.”

“The tractive effort of the machine seems weak, especially in this deep snow that we have now.”
