    Prednisolone glaucoma


    Several different drugs have the potential to cause the elevation of intraocular pressure (IOP), which can occur via an open-angle mechanism or a closed-angle mechanism. Steroid-induced glaucoma is a form of open-angle glaucoma that usually is associated with topical steroid use, but it may develop with inhaled, oral, intravenous, periocular, or intravitreal steroid administration. Medications prescribed for a variety of systemic conditions (eg, depression, allergies, Parkinson disease) can produce pupillary dilation and precipitate an attack of acute angle-closure glaucoma in anatomically predisposed eyes that have narrow angles. Drug-induced elevation of IOP is more common by an open-angle mechanism. Corticosteroids are a class of drugs that may produce IOP elevation by this mechanism. Not all patients taking corticosteroids will develop elevated IOP. Risk factors include preexisting primary open-angle glaucoma, a family history of glaucoma, high myopia, diabetes mellitus, and history of connective tissue disease (especially rheumatoid arthritis). Elevation of IOP has been associated with both ocular and systemic administration of steroids (e.g. topical application to the eye or eyelids, sub-Tenon’s injection, intra-vitreal injection [or implant], steroid by mouth) If the elevated IOP is of sufficient magnitude and duration, damage to the optic nerve can occur with resulting visual field loss (steroid glaucoma) The mechanism of elevated intraocular pressure is increased aqueous outflow resistance owing to an accumulation of extracellular matrix material in the trabecular meshwork With regard to this ‘steroid response’ the normal population can be divided into three groups: The higher the steroid potency, the greater the ocular hypertensive response. The ophthalmic steroids dexamethasone and prednisolone acetate are more likely to result in clinically significant increases in IOP when compared to fluorometholone and loteprednol. Primary open angle glaucoma (POAG) First degree relative with POAG Childhood High myopia Diabetes None in the early stages; visual loss later Raised intraocular pressure following use of topical steroid If optic neuropathy is present, the condition clinically resembles POAG (although higher IOP compared to POAG, resulting in more rapid visual field and optic disc changes) Can occur at any time (within weeks with potent drugs and after several months with weaker agents); onset rare with less than 3 weeks’ exposure POAG Ocular hypertension Secondary glaucoma (pigment dispersion, pseudo-exfoliation, neovascular, inflammatory [e.g. Posner-Schlossman syndrome or following anterior uveitis]) Practitioners should recognise their limitations and where necessary seek further advice or refer the patient elsewhere Level of evidence and strength of recommendation always relates to the statement(s) immediately above A baseline measurement of IOP should always be taken prior to commencement of steroid therapy. Patients newly begun on ocular steroid therapy should have their IOPs measured again after 2 weeks, then every 4 weeks for 2-3 months, then 6-monthly if therapy is to continue It has been recommended in patients receiving intravitreal steroids (injections or implants) to measure IOP at 30 minutes, at 1 week, 2 weeks and monthly for up to 6 months If a steroid response is detected, discuss with the prescribing clinician the possibility of discontinuing steroid therapy (the chronic steroid response usually resolves in 1-4 weeks, whilst the acute response may resolve within a few days of cessation of steroid therapy) Patient may need topical anti-glaucoma medication (discuss with prescribing clinician) A3: possible first aid measures followed by urgent referral to an ophthalmologist If the optometrist is the prescribing clinician, discontinue steroid or switch to ‘non-penetrating’ steroid and monitor IOP until it reaches an acceptable level. Patient may need short-term ocular hypotensive medication.

    Glaucoma or cataracts eye conditions. Prednisolone comes in various formulations, including a tablet, a solution, a syrup, a liquid, a suspension, and a disintegrating tablet. Mar 14, 2017. Many different drugs have the potential to elevate eye pressure and increase the risk of developing glaucoma. This article explores the classes. Open-Angle Glaucoma. Oral steroids are the most important medication that can affect open-angle glaucoma, the most common type of glaucoma, and can also raise eye pressure in patients with angle-closure glaucoma.

    There are hundreds of pills for which the FDA statements about the drug include a glaucoma caution, that is, they say that it may be dangerous for glaucoma patients to take them. Among these are the many medicines used for anxiety and psychological disorders, things like the serotonin reuptake inhibitors, the first of which was Prozac (fluoxetine). Apparently, there were reported examples of angle closure glaucoma that happened in those taking this pill. The same could occur with all the frequently used drugs that help with urinary incontinence and with some of the upper respiratory cold pills. For all of these, the risk is that the pupil might be dilated, and angle closure might result. But, for all those with open angles, these medications are perfectly fine. And, they’re fine for any angle closure person who has already had an iridotomy (see section ). Question submitted by Srinivas Iyengar, MD, second-year resident, Department of Ophthalmology, University of Kansas Medical Center, Kansas City. One third of the population may experience an increase in IOP in response to the local or systemic use of corticosteroids, but the response varies among individuals. Specifically, the IOP rose from a mean of 16.9 to 32.1 mm Hg in patients diagnosed with glaucoma, from a mean of 17.1 to 28.3 mm Hg in glaucoma suspects, and from a mean of 13.6 to only 18.2 mm Hg in control subjects without glaucoma. Comparison of in vitro potency of corticosteroids with ability to raise intraocular pressure. The increase in IOP noted with steroid therapy appears to be dose and time dependent. Most patients with elevated IOP in steroid-response glaucoma experience a return to pretreatment IOP levels within 10 days to 3 weeks after the discontinuation of steroid therapy. The recent increase in the use of intravitreal steroid injections for posterior segment conditions has led to a greater incidence of ocular hypertension due to the higher level of localized exposure to steroids. Intractable glaucoma following intravitreal triamcinolone in central retinal vein occlusion. These cases are difficult to manage, because the surgeon cannot remove the offending agent without performing a vitrectomy.

Steroid-induced glaucoma affects the trabecular meshwork of the eye, caused by the effects of corticosteroids - any of several steroid hormones secreted by the cortex of the adrenal glands, or any synthetic forms with similar properties. With this form of glaucoma, raised intraocular pressure is due to the reduced outflow facility of the. The higher the steroid potency, the greater the ocular hypertensive response. The ophthalmic steroids dexamethasone and prednisolone acetate are more likely.
