Bilateral juvenile open-angle glaucoma with keratoconus: A rare association and literature review

Juvenile open-angle glaucoma (JOAG) is a subset of primary open-angle glaucoma, which affects individuals aged 5 to 35 years. Keratoconus is a bilateral progressive ectatic disorder of the cornea that results in a reduction of vision due to irregular astigmatism. The exact cause and the underlying pathological mechanism are unknown, but both environmental and genetic factors are thought to contribute to the development of the disorder. The association between keratoconus and normal-tension glaucoma has been widely published in literature, whereas the association between keratoconus and JOAG has been reported rarely. This is the third case report pointing toward the possible association of juvenile glaucoma with keratoconus, which emphasizes the importance of thorough glaucoma evaluation among keratoconus patients.
