    Question:

    Is laser peripheral iridotomy the best treatment for "narrow angle" glaucoma?


    Answer:

    Having a "narrow angle" (when the colored part of your eye is pushed too far forward) can put one at risk for both an acute angle closure glaucoma attack and chronic angle closure glaucoma (where scarring causes damage to the drain). Treatment often begins with a laser peripheral iridotomy (LPI), since that can help to lessen pupillary block — one component of narrow angles where fluid gets trapped between the iris and the lens. Unfortunately, other structures in the back of the eye can also contribute to a narrow angle, so it is difficult to say that an LPI is the best treatment. I can comfortably say, however, that it is usually the first treatment.
