Glaucoma and retinal detachment. 1977

C D Phelps, and T C Burton

In a survey of 817 patients undergoing primary operations for retinal detachment, glaucoma was present in 9.5%. Ocular hypertension (intraocular pressure [IOP] greater than 21 mm Hg) was present in an additional 6.5%. Primary open-angle glaucoma; the type of glaucoma most frequently encountered, occurred in 4% of the patients. Aphakic eyes and eyes with peripheral anterior synechiae had high prevalences of glaucoma. A high percentage of eyes with posttraumatic angle recessions had either glaucoma or elevated IOPs. Miotics used in the treatment of glaucoma could not be definitely implicated as a cause of retinal detachment. The rate of successful retinal reattachment was the same, whether or not glaucoma was present. However, a good visual result occurred less frequently in patients with glaucoma.

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
D008916	Miotics	Agents causing contraction of the pupil of the eye. Some sources use the term miotics only for the parasympathomimetics but any drug used to induce miosis is included here.	Miotic Effect,Miotic Effects,Effect, Miotic,Effects, Miotic
D012163	Retinal Detachment	Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery.

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.
