Increased intraocular pressure after ocular procedure

Increased intraocular pressure after an ocular procedure is an acute or subacute complication affecting the visual system, characterized by a pathologically elevated pressure within the eye following ophthalmic surgical or laser interventions such as cataract extraction, vitrectomy, trabeculoplasty, or capsulotomy It occurs primarily due to mechanical, inflammatory, or foreign-material obstruction of the trabecular meshwork, resulting in compromised aqueous humor outflow Defining pathophysiologi...

It occurs primarily due to mechanical, inflammatory, or foreign-material obstruction of the trabecular meshwork, resulting in compromised aqueous humor outflow Defining pathophysiologic mechanisms include mechanical blockage by retained ophthalmic viscosurgical devices, intraocular gas or silicone oil expansion, pigment or erythrocyte dispersion, and secondary corticosteroid response While often transient, these intraocular pressure spikes can cause corneal edema, ocular pain, and acute optic ne...

While often transient, these intraocular pressure spikes can cause corneal edema, ocular pain, and acute optic nerve ischemia, especially in vulnerable populations with preexisting glaucomatous neuropathy
