One of the most plebeian ophthalmic symptom in the middle and old - age people is increased pressure behind the eye , which is also promise as raise intraocular press in clinical terminology . This may pose augury ofheadache , vertigo , difficulty in vision , pulsate tactile sensation in the eye , etc . and guide to the disease of glaucoma . There are various factors lead to the development of this imperativeness and persistent raised intraocular insistency may result in some serious permanent hurt leading to complete loss of imaginativeness or blindness . So , it becomes imperative to know about the intraocular pressure or pressure behind the optic .
What is Intraocular Pressure?
The insistence felt by the stratum of the orb due to bearing of intraocular fluid is known as IOP or intraocular press . These fluid are release by the ciliary processes behind the sword lily and drained through the trabeculate flow and uveoscleral flow . Though the normal IOP ranges between 10 and 21 mmHg or 16 ± 2.5 mm of Hg yet , any upset in secretion or drain or tub can direct to additional accumulation of fluid inside the chamber resulting in increased intraocular pressure . This can be superintend medically as well as surgically but before that we have to sympathise what cause pressure to rise .
Causes of Increased Pressure behind the Eye
Local Factors
pace of fluid formation directly affects IOP . The constitution of aqueous humor also depends on other factor like permeability of capillaries and hemodynamic osmolarity .
Resistance in drain or outflow . Clinically , restricted effluence is the most important factor . more often than not , this resistance shape at the meshing of trabeculate net .
raise episcleral venous press is directly relative to increase intraocular force per unit area . This pressure can be increased temporarily by Valsalva maneuver .
Refractive errors such asmyopiamay raise the IOP due to relative obstruction of the iris compromise drainage of the fluid .
General Factors
How Do You Get Rid Of Pressure Behind Your Eye?
Proper direction should be done to diminish pressure behind the oculus ball . Before starting any clinical method acting of treatment it is necessary to consider some pre - medication profiling .
General Considerations
rank of severity and service line evaluation of glaucoma – Motive behind this intervention is to lower the intraocular imperativeness for prevent further loss of visual modality . It intend that treatment requires maintenance and has to be done under regular supervising of aesculapian practitioner . To secure the discourse is work , a baseline examination is carried before start the treatment . This admit : examination of anterior chamber , ocular visual acuity , thickness measurement of central cornea , tonometry , and rating of ocular disc , visual field charting and gonioscopy .
Grading can be done fit in to ( AAO ) .
Choices of Therapy
Medical Therapy
Single Drug Therapy . Drugs for glaucoma are used . These include-
Combination Therapy ( Topical ) . Timolol + β - blocker or brimonidine ( + lantanoprost or pilocarpine ) .
Carbonic Anhydrase Inhibitors ( unwritten ) . Acetazolamide ( 250 mg tds ) , Methazolamide . They are forbidden to recommend for long term consumption .
Hyperosmotic Agents . Mannitol ( 1 - 2 gm / kg of body weight ) .
Neuroprotective Agents . It is a method acting to cover damaged retinal ganglionic cells .
Laser Trabeculoplasty
Surgical intervention
