Does elevated intraocular pressure cause retinal detachment?

No. These are two unrelated conditions. Elevated pressure in the eye can cause permanent blindness, but does not in any way cause the retina to detach.
No. Glaucoma doesn't cause a retinal detachment, but a retinal detachment can cause high eye pressure and glaucoma (i.e. Schwartz syndrome, also hemorrhagic rd, other). However, usually the eye pressure is low if there is a large retinal detachment.

Can an increase in eye pressure lead to retinal detachment?

No. Retinal detachment and glaucoma are independent variables. Neither causes the other. In the course of evaluation for suspected retinal detachment, the eye pressure is always measured so sometimes glaucoma will be detected by the retinal surgeon. Read more...
