Introduction
Although most forms of glaucoma occur with increased intraocular pressure, normal-pressure glaucoma* is a recognized entity.
* The pathophysiology is not well understood.
Etiology
- see specific form
- pharmaceuticals
- glucocorticoids (open-angle glaucoma)[8]
- certain antineoplastic agents (open-angle glaucoma)[8]
- NSAIDs (angle-closure glaucoma)[7]
- parasympatholytics (angle-closure glaucoma, pupillary block)[8]
- adrenergic agents (angle-closure glaucoma, pupillary block)[8]
- sulfa drugs (angle-closure glaucoma, non-pupillary block)[8]
Epidemiology
- prevalence: 2-5% age > 60, 10% age > 80
- risk factors:
- increased intraocular pressure
- age > 60
- most common cause of blindness in African-Americans
- family history - 40 % prevalence among 1st degree relatives
- diabetes mellitus
- myopia
- previous eye surgery or trauma
- history of cataracts
- alcohol consumption
- prolonged mechanical ventilation - uncommon
- glucocorticoids
Pathology
- increased pressure of the fluid in the eye
- damage to the small internal blood vessels &/or optic nerve fibers
- optic nerve fiber destruction & partial or complete loss of vision
- degeneration of retinal ganglion cells
- higher intraocular pressure variability may be associated with faster structural changes in patients with glaucoma[16]
Clinical manifestations
- onset is insidious & often not recognized by the patient until late in the course of the disease
- peripheral vision is lost 1st as the optic nerve degenerates
Diagnostic procedures
- ophthalmoscopy
- increases in cup/disk ratio of > 0.6 consistent with glaucoma
- asymmetry in size or contour of the cup is suspicious for glaucoma
- gonioscopy
- tonometry
- perimetry
- image analysis
- aids in evaluating optic disk to neuroretinal rim area changes seen before loss of vision
- diagnosis of low & normal tension glaucoma
- equipment is expensive
Complications
- no association between either prevalent or incident glaucoma & cognitive impairment[15]
- glaucoma, cataracts, & age-related macular degeneration may increase risk of falls in the elderly[17]
Management
- see more specific type
Clinical trials
- clinical trials of glaucoma therapy can be completed within 18 months[13]
