[OS X TeX] \langle does not display as such in the Index

I am proofreading a bit and just noticed that: 

\langle displays correctly under showidx but under makeidx displays   hA   
and 
\rangle displays correctly under showidx but under makeidx  displays   A with a little cup on top followed by B

Similarly, 

\left \langle displays correctly with showidx but under makeidx displays CircleCross A
and
 \right \rangle displays correctly under showidx but under makeidx displays a dropped A with a little cup on top followed by B


I am using

			\let\oldopenparen\(%
			\let\oldcloseparen\)%
			\newcommand{\INDEX}[1]{\def\({\protect\oldopenparen}\def\){\protect\oldcloseparen}\index{#1}}

which works fine with every other symbols.

Puzzled regards
