Secondary open up-angle kind glaucoma is due to injuries, eye sickness, and rarely eye surgical treatment leading to greater intraocular tension and, therefore, optic nerve injury much like the open up-angle sort of glaucoma. A person system of secondary open up-angle glaucoma is from laser surgical procedure, which might result in pigment release, inflammatory cells, debris, and mechanical deformation leading to blockage on the trabecular meshwork resulting in enhanced intraocular force. The commonest system for that secondary open up-angle variety is from disorders producing neovascularization. Neovascularization can possibly bodily block the outflow tracts.[10] Pseudoexfoliative sort is when flaky content peels off the outer lens capsule and collects within the angle, clogging the trabecular meshwork, leading to improved eye strain. Pigmentary sort is similar to click here exfoliative except the particles are pigment granules within the again on the iris that split off and clog the trabecular meshwork as a result of contact with the peripheral lens capsule and zonules in typically myopic, or near-sighted eyes.
