Pupillary block associated with posterior chamber lenses
Ophthalmic Surgery
|February 1, 1985
Summary
Pupillary block glaucoma can occur after cataract surgery without peripheral iridectomies. Laser iridotomy effectively controlled intraocular pressure in two patients, avoiding long-term medication.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Glaucoma Research
Background:
- Extracapsular cataract extraction (ECCE) with posterior chamber lens (PCL) implantation is a common procedure.
- Peripheral iridectomies are often performed concurrently to prevent pupillary block.
- The necessity of peripheral iridectomies in all ECCE cases is debated.
Observation:
- Two patients developed acute pupillary block glaucoma post-ECCE with PCL implantation.
- These patients did not undergo prophylactic peripheral iridectomies.
- Elevated intraocular pressure (IOP) was noted in both cases.
Findings:
- Laser iridotomy was performed on the affected eyes.
- Successful IOP control was achieved in both patients following laser treatment.
- No long-term ocular hypotensive medication was required.
Implications:
- Laser iridotomy is a viable and effective treatment for acute pupillary block glaucoma after ECCE.
- Peripheral iridectomies may not be mandatory in all ECCE procedures.
- This approach can prevent the need for chronic glaucoma medication.
