What is the primary cause of secondary glaucoma?

Secondary glaucoma occurs as a result of an underlying eye condition, which means that the primary cause stems from other disorders affecting the eye. Conditions such as uveitis, ocular tumors, or lens dislocation can lead to increased intraocular pressure, hence resulting in secondary glaucoma. The disease process related to these conditions disrupts normal fluid drainage from the eye, ultimately causing damage to the optic nerve if left untreated.

Understanding that secondary glaucoma is directly linked to these pre-existing eye issues is crucial for effective diagnosis and treatment. While genetic factors and systemic health issues may play a role in the overall spectrum of glaucoma or its risk factors, the defining characteristic of secondary glaucoma is that it is triggered by identifiable ocular conditions rather than being an independent disorder.
