Simultaneous angle closure in twins
Purpose:
This article reports identical twin sisters who were found to have acute angle-closure glaucoma at the same time.
Methods:
Two case reports.
Results:
Two 73-year-old identical twin sisters presented to the emergency room with a complaint of decreased vision and eye pain after having been in a fist fight with each other the previous night. One sister exhibited signs of angle-closure glaucoma with an intraocular pressure > 50 mmHg in the left eye, while her twin sister presented with bilateral angle-closure glaucoma and similar intraocular pressures. Both patients were treated with anti-glaucoma medications and bilateral laser iridotomies.
Conclusions:
Polygenetic factors influence the configuration of the anterior chamber, but other environmental factors contribute to the risk of developing primary angle-closure glaucoma. Potentially occludable angles are more common in individuals with a first-degree relative with acute angle closure. Screening of these patients (especially twins) for occludable angles is recommended.

Equivalent Couples
Two couples are considered to be equivalent if they produce the same rotational effect on a rigid body. In other words, the two couples have the same magnitude and act in the same direction, causing the same angular displacement or acceleration in the body.
For instance, consider two couples lying in the plane of the page, with one having a pair of equal...
