Macular holes

Ophthalmology Clinics of North America, 2002
Spontaneous closure of macular holes occurs in 3% to 9% of patients over 6 years [3,58]. Visual acuity can recover dramatically once the hole closes. The risk for hole development in the fellow eye in the absence of PVD is approximately 29%. The presence of vitreomacular separation reduces the risk to less than 5%.

Macular Holes

Albrecht von Graefe's Archive for Clinical and Experimental Ophthalmology, 1980
Twenty-four eyes with macular holes have been followed for periods ranging from one to four years. Each hole was demonstrated, clinically, to be full thickness and associated with a small, localized, retinal detachment and a posterior vitreous separation.

Black Holes

2009
Abstract A black hole is an object that is inside its event horizon at r=r*: a one-way surface that particles and light can only traverse inward. This chapter studies the spherically symmetric nonrotating Schwarzschild black hole. The metric elements change their respective signs when crossing from r>r∗ to r<r*, leading to ...
