In games, these quizzes are often unrelated to gameplay: gameplay can be viewed as a reward for answering quiz questions.

The retinal nerve fibre layer thickness in glaucomatous hydrophthalmic eyes assessed by scanning laser polarimetry with variable corneal compensation in comparison with age-matched healthy children.

Purpose: To compare the thickness of the retinal nerve fibre layer (RNFL) in hydrophthalmic glaucomatous eyes in children with age-matched healthy controls using scanning laser polarimetry with variable corneal compensation (GDxVCC).

Methods: Twenty hydrophthalmic eyes of 20 patients with the mean age of 10.64 ± 3.
