Clouding of the lens capsule, or posterior capsule opacification, only occurs as a side effect of cataract surgery. This is a good thing for both patients and surgeons alike. Topical ophthalmic prostaglandin analogs work by increasing aqueous outflow. The anterior chamber depth is usually normal. The chronic form may develop after acute angle closure where synechial closure of the angle persists, or it may develop over time as the angle closes from prolonged or repeated contact between the peripheral iris and the TM, which often leads to peripheral anterior synechiae (PAS) and functional damage to the angle.

With control of the IOP, progressive visual deterioration can be controlled. Systemic carbonic anhydrase inhibitor chronic therapy is uncommonly used because of the many adverse effects of systemic use, and should be reserved for patients with glaucoma refractory to other medical treatment. Blown pupils are fixed, dilated pupils that do not react to light. Acute: abrupt onset of symptomatic elevation of IOP (>21mmHg), resulting from total closure of the angle, which is not self-limiting. These agents cause pupil constriction with thinning of the iris and its pulling away from the inner eye wall and TM, thus opening the angle. The highest rates are reported in Inuit and Asian populations, and lowest rates are reported in African and European populations. Half of cases leading to blindness are estimated to result from PACG. We employ a Mask R-CNN architecture as a segmentation algorithm to segment the pupil and iris with pixel-based accuracy and then track their sizes across the entire video.

The optic nerve head should be investigated by slit-lamp examination or funduscopy, and may show typical changes of glaucoma such as a large optic cup and nerve fiber loss. Patients with primary angle-closure glaucoma (PACG) often present with higher IOP and more advanced visual field loss than those with primary open-angle glaucoma (POAG). What causes an unresponsive pupil after cataract surgery? Immediately following cataract surgery, people may experience impaired vision, such as blurry or double vision.
