About This Presentation

Description : Check out this medical PowerPoint presentation titled "Acute Glaucoma Conditions” by Dr. Sonya Bennett.

This medical PowerPoint presentation is about Acute glaucoma, also known as acute angle-closure glaucoma, is a serious eye condition that can cause sudden and severe vision loss. It occurs when the fluid pressure inside the eye (intraocular pressure) increases rapidly and blocks the drainage of the fluid out of the eye.

Symptoms of acute glaucoma may include:

Severe eye pain
Blurred or hazy vision
Halos around lights
Redness in the eye
Headache
Nausea and vomiting

If you experience these symptoms, it is important to seek medical attention immediately as untreated acute glaucoma can cause permanent vision loss.

Treatment for acute glaucoma typically involves reducing the intraocular pressure as quickly as possible. This can be done with eye drops, oral medications, or in severe cases, with surgery. Your eye doctor will determine the best course of treatment based on the severity of your condition.

Acute Glaucoma Conditions Acute Eye Conditions Course Dr. Sonya Bennett
Slide 2-

Glaucoma isn’t usually thought of as an emergency condition........ unless it’s that bad one aka “acute glaucoma”

Slide 4-

Classification Primary angle closure ± glaucoma Secondary angle closure ± glaucoma Acute angle closure crisis Primary open angle glaucoma Secondary open angle glaucoma
Slide 5-

Primary Angle Closure drainage angle occludable from primary mechanism (iris trabecular meshwork contact in three or more quadrants), with either raised IOP and/or primary peripheral anterior synechiae and if optic nerve damage = glaucoma
Slide 6-

Slide 8-

Secondary Angle Closure similar clinical findings in angle/AC though caused by “posterior pushing mechanism”: secondary pupil block from uveitis (seclusio pupillae and iris bombe) lens induced - phacomorphic, anterior subluxation, traumatic lens dislocation malignant glaucoma
Slide 9-

Secondary Angle Closure Retinopathy of prematurity / PHPV Choroidal expansion from: drugs, posterior scleritis, AIDS, PRP, arteriovenous fistulas anterior neovascularisation
Slide 10-

Acute Angle Closure Crisis complete occlusion of drainage angle resulting in sudden elevation of intraocular pressure (IOP) Clinical signs: hazy cornea, fixed mid-dilated pupil, IOP >21mmHg, shallow anterior chamber Symptoms: blurred vision, nausea & vomiting, headache

Slide 12-

Acute Angle Closure Crisis Examination: VA, IOP, slit-lamp examination, gonioscopy, undilated optic disc viewing, fellow eye assessment think about and look for the mechanism of closure during the examination
Slide 13-

Acute Angle Closure Crisis Medical management Eyedrops: beta blockers, alpha agonists, carbonic anhydrase inhibitors and pilocarpine oral or intravenous acetazolamide oral hyperosmotic agent (glycerol) if safe for patient
Slide 14-

Acute Angle Closure Crisis Medical Management Intravenous hyperosmotic agents (mannitol) it safe for patient topical glycerin/glycerol eyedrops to improve the view topical steroids
Slide 15-

Acute Angle Closure Crisis Surgical treatment peripheral iridoplasty early if IOP not lowering AC paracentesis for temporary IOP lowering - usually reserved for cases where other treatment has failed Laser peripheral iridotomy: YAG, argon/diode. Treat fellow eye also!
Slide 16-

Acute Angle Closure Crisis Surgical treatment Lens extraction - often effective in refractory cases and/or if significant cataract present trabeculectomy not usually performed (50% failure rate)
Slide 17-

Acute Angle Closure Crisis if you are sure of a secondary non pupil block mechanism (especially if it is atypical and asymmetric) then use atropine

Case NM 91 yr old frail woman (double amputee)referred from rest-home with three week history of red aching eyes and reduced vision bilaterally seen at local private practice: VA HM, 3/60; IOP 68, 53 mmHg, hazy corneae and shallow ACs diagnosed with acute angle closure crisis: topical timolol, brimonidine, pred forte and oral diamox 250mg administered
Slide 20-

Case NM arrived at GCC A&E: IOP 54, 48. Bilateral YAG Laser peripheral iridotomy performed IOPs one hour later were 18, 14 discharged home on combigan BD and pred forte Q2hrly OU
Slide 21-

Case NM returned for review 2 days later: IOP 46,23 corneae a little clearer, difficult view of disc as very dense cataracts drainage angle closed synechially in 3/4 quadrants OD
Slide 22-

Case NM phaco/PCIOL OD 2 days later, subTenon’s anaesthesia generalised zonule weakness noted intraoperatively so capsular tension ring inserted corneal oedema gradually settled and UAVA 6/9 optic nerve OD 0.9
Slide 23-

Case NM IOPs 17, 14 on Latanoprost nocte, Combigan BD OU planning phaco/PCIOL OD in the next month or two - VA 6/18, angle very narrow but open in 2 quadrants, hazy view of disc 0.3
Slide 24-

Open Angle Glaucoma Emergencies If IOP > 40mmHg Primary: not common, but possible (younger) Secondary: trauma-related, steroid response, hyphaema, pigment dispersion syndrome, pseudoexfoliation, Posner-Schlossman syndrome, phacolytic glaucoma, ghost cell glaucoma
