What is the mechanism for Subacute or Intermittent Angle Closure?
What is the correct treatment for Subacute Angle Closure? |
A partial angle closure that can seen in dim lighting which leads to pupil dilation and block
Subacute or Intermittent Angle Closure is mostly treated by surgery. Long term medical management is not appropriate. Treatment involves LPI first followed by Iridoplasty if necessary. Sometimes a Trabecultectomy (Filtering Surgery) is necessary. |

What is the mechanism for Chronic Angle Closure?
What is the correct treatment for Chronic Angle Closure? |
Chronic Angle Closure involves a slow zippering of the angle shut, especially in the superior angle. Mechanisms is more creeping angle instead of pupil block. Patient's are asymptomatic and is usually discovered on a routine exam.
Treatment involves LPI first, then medications followed by a Trabecultectomy (Filtering Surgery) if not controlled. Will require topical medications following LPI to control IOP due to chronic TM damage. Prostaglandins are drug of choice and work exceptionally well even in cases of complete angle closure with PAS. |

What is the treatment for Plateau Iris Syndrome?
|
Argon Laser Iridoplasty is quite effective and is treatable with Pilocarpine.
|

|
What is the mechanism for Ciliary Block Glaucoma?
What are the two there names given for CBG? What is the treatment for Ciliary Block Glaucoma? |
Anterior displacement of the iris and ciliary body which causes misdirection of aqueous into the vitreous and the posterior chamber with anterior displacement of the structure of the eye. This is most typically occurs folloeing ocular surgery for angle closure glaucoma (Trabecuectomy).
Malignant Glaucoma and Aqueous Misdirection Syndrome Best managed with Cycloplege and Steroids: - Atropine 1% BID - Topical Steroids - AQS --> Possible Diamox 1 gram PO QD (dehydrates and shrinks the vitreous (Eventually everything is tapered but Atropine.) Surgical options include: Vitrectomy and Lensectomy Chandler's Procedure |

What is the treatment for Acute Angle Closure secondary to Choroidal Expansion?
|
Topical Steroids
Atropine Beta Blockers Alpha-2 Agonists Discontinue precipitating medications No LPI |
|
|
What is the treatment for Acute Angle Closure secondary to Pupil Block?
|
AQS
Prostaglandins Pilocarpine Steroids LPI |
|
|
What is the treatment for ICE syndromes?
|
1) Trabeculectomy
2) Penetrating Keratectomy |
|
|
What is the treatment for Acute Primary Angle Closure?
What is the goal of this treatment? |
To relieve Corneal Edema:
1) Glycerin 2) Corneal Indentation AQS - Beta Blocker (1 DROP) - Iopidine or Alphagan (x2) - CAI - Diamox 500 mg Pilocarpine 2% (if <40mmHg) Prostaglandin (may not work fast enough in an acute situation) Pred Forte Q15min-Q30min Osmoglyn Surgical therapy: LPI Iridectomy with Trabeculectomy Argon Laser Iridoplasty Goal is not to reduce the IOP, but to change the Angle Anatomy. Pressure reduction is merely part of the process. |

|
What is the treatment for Primary Angle Closure Attack?
|
1) Medical therapy
2) LPI 3) Iridoplasty 4) Trabeculectomy |
