Summary
Risk factors for elevated intraocular pressure (IOP) after cataract surgery include higher baseline IOP, male sex, glaucoma, Black race, and older age. Diabetes and postoperative aphakia appear protective against IOP spikes.
Area of Science:
- Ophthalmology
- Clinical Research
- Surgical Outcomes
Background:
- Elevated intraocular pressure (IOP) post-cataract surgery can lead to complications.
- Identifying risk factors is crucial for patient management and mitigating adverse events.
Purpose of the Study:
- To evaluate risk factors associated with intraocular pressure (IOP) spikes following cataract surgery.
- Utilize the IRIS® Registry (Intelligent Research in Sight) for comprehensive data analysis.
Main Methods:
- Retrospective cohort study analyzing data from the IRIS Registry.
- Included adults undergoing stand-alone phacoemulsification between January 2013 and September 2019.
- Defined IOP spike as postoperative IOP > 30 mmHg and > 10 mmHg from baseline within the first week; calculated odds ratios (ORs) using logistic regression.
Main Results:
- An IOP spike occurred in 3.7% of 1,191,034 analyzed eyes.
- Increased risk associated with higher baseline IOP, male sex, glaucoma, Black race, older age, and complex surgery coding.
- Diabetes and postoperative aphakia showed protective effects; specific glaucoma subtypes presented varied risk profiles.
Conclusions:
- Higher baseline IOP, male sex, glaucoma, Black race, older age, and complex cataract coding are linked to early postoperative IOP spikes.
- Diabetes and postoperative aphakia may be protective.
- Understanding these factors aids surgeons in stratifying and managing the risk of IOP spikes.

01:25Glaucoma: Overview
574
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:28Angle Closure Glaucoma: Treatment
500
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:27Open Angle Glaucoma: Treatment
453
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
