Top-ten of the First Meeting of the Asian Angle-Closure Glaucoma Club (AACGC)
November 7-8, 2002, Seoul, Korea
Chul Hong
The significance of the meeting was that topics and hot issues regarding angle-closure glaucoma, which is highly prevalent in Asians, were presented and discussed during a meeting of a specific interest group, the AACGC. The creation of a new classification for angle-closure glaucoma was also proposed. The second meeting will take place in Bangkok in November 2003, and the third in Beijing in 2004. Top-ten issues presented at the meeting were as follows:
- Chinese eyes have been recognized to be prone to the development of creeping angle closure, and there has been some direct evidence to support that creeping angle closure is caused by a multi-mechanism.
- There was little change in central anterior chamber depth and movement of lens position after both laser iridotomy and trabeculectomy in angle-closure glaucoma patients
- In narrow-angle eyes with peripheral anterior synechiae, appositional angle closure frequently occurs, particularly where PAS exists.
- Ultrasound biomicroscopic evaluation of the angle recess area in normal Japanese subjects showed that the angle recess area decreases with age.
- Gonioscopy with infrared light can be useful for studying the anterior chamber angle in dim light or total darkness.
- Measurement of mid-peripheral anterior chamber depth was a useful tool for evaluating the anterior chamber angle and predicting the possibility of elevation of the intraocular pressure by angle closure.
- In chronic angle-closure glaucoma, optic disc cupping is increased in all directions including depth, predominantly in the inferotemporal and superotemporal directions.
- Image analysis, including biometry, chamber angle analysis, and optic nerve head analysis, is an important tool for detecting and evaluating primary angle-closure glaucoma.
- Occludable angles should be carefully examined and followed up, especially in Asians because of their high incidence in these patients and their potential to develop toward angle-closure glaucoma.
- A postoperative, shallow anterior chamber was a significant risk factor for surgical failure in primary angle-closure glaucoma
