The mechanism of accommodation in primates1☆

Presented in part at the American Academy of Ophthalmology Refractive Surgery Subspecialty Day Program, San Francisco, California, October 1997, and at the Association for Research in Vision and Ophthalmology annual meeting, Fort Lauderdale, Florida, May 1998.

Objective

To study the accommodative mechanism in primates using monkeys, in light of a recently proposed novel accommodative mechanism in primates and a concomitant controversial surgical procedure for the reversal of presbyopia,
Design

Experimental study.
Methods

Accommodation was induced by stimulation of an electrode surgically implanted in the midbrain and by topical ocular application of muscarinic agonists. Pharmacologic disaccommodation was achieved by topical application of a muscarinic antagonist. Movements of the lens equator and the ciliary body were imaged during accommodation and disaccommodation using ultrasound biomicroscopy and goniovideography, and the images were analyzed to determine the direction and the extent of the movements.
Results

Despite the systematic eye movements occurring with electrical stimulation and the nonsystematic eye movements occurring with pharmacologic stimulation, in all instances the ciliary body and the lens equator moved away from the sclera during accommodation.
Conclusions

Movement of the accommodative structures is consistent with the classic mechanism of accommodation described by Helmholtz, and contrary to that recently proposed by Schachar.

Ophthalmist,

Слишком обще, все это можно по полочкам разложить и задать 10-ть наводящих вопросов на которые ответов не будет. И вообще из этого текста ничего не следует.

Из этого - нет, для жаждущих подробностей - легко найти полный текст статьи. В основном этот текст - как пособие для фанатов работы глазных мышц как аккомодаторов. На счёт действия хориодеи - думаю можно поискать в полном тексте статьи.
