OBJECTIVE To summarize the recent advances in the management of patients with coexisting cataract and glaucoma. RESULTS Although some evidence suggests that cataract surgery may be useful in the clinical management of eyes with angle closure glaucoma, recent studies show that the decrease in intraocular pressure (IOP) following cataract surgery alone in eyes with open angle glaucoma may be limited and transient. Combining cataract surgery with a trabeculectomy remains the preferred option. However, when IOP lowering is indicated, newer surgical techniques to lower IOP to be performed along with cataract extraction offer a promising alternative in patients with uncontrolled glaucoma and a visually significant cataract. CONCLUSIONS Cataract surgery alone or combined with trabeculectomy should be considered in the treatment of angle closure glaucoma. However, in eyes with open angle glaucoma, cataract surgery alone may be of limited clinical benefit in lowering IOP. Surgical alternatives to be combined with cataract extraction may be utilized to achieve a more significant IOP reduction. The appropriate treatment should be tailored based on patient's characteristics and the target IOP to be achieved.

UI MeSH Term Description Entries
D007429 Intraocular Pressure The pressure of the fluids in the eye. Ocular Tension,Intraocular Pressures,Ocular Tensions,Pressure, Intraocular,Pressures, Intraocular,Tension, Ocular,Tensions, Ocular
D002386 Cataract Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence).

D005901 Glaucoma An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.

D014130 Trabeculectomy Any surgical procedure for treatment of glaucoma by means of puncture or reshaping of the trabecular meshwork. It includes goniotomy, trabeculectomy, and laser perforation. Goniotomy,Trabeculoplasty,Trabeculotomy,Goniotomies,Trabeculectomies,Trabeculoplasties,Trabeculotomies
D018918 Phacoemulsification A procedure for removal of the crystalline lens in cataract surgery in which an anterior capsulectomy is performed by means of a needle inserted through a small incision at the temporal limbus, allowing the lens contents to fall through the dilated pupil into the anterior chamber where they are broken up by the use of ultrasound and aspirated out of the eye through the incision.
