Lessons From Management: Perioperative Phacoemulsification Planning Following Resolution of Acute Angle Closure.

Cureus 2021 Apr 6;13(4):e14331. Epub 2021 Apr 6.

Faculty of Medicine, University of New South Wales, Sydney, AUS.

Patients with loose zonular apparatus after acute angle closure may require phacoemulsification cataract surgery. The authors' experience from management of such patients provides excellent instruction on the surgical intervention for their cataracts. This is because patients who have recovered from acute angle closure glaucoma may not have evident zonular laxity preoperatively, as the iris may be taut secondary to the effects of associated ischaemia.

Changes in peri-ocular anatomy and physiology in pseudoexfoliation syndrome (Review).

Exp Ther Med 2021 Jun 19;21(6):650. Epub 2021 Apr 19.

Laboratory of Clinical Virology, Medical School, University of Crete, Heraklion 71003, Greece.

Pseudoexfoliation syndrome (PEX) is characterized by the deposition of proteinaceous material in the anterior ocular segment (resulting in ophthalmic pathologies such as glaucoma and increased risk of complications in cataract surgery), but also by several systemic manifestations. The involvement of peri-ocular tissues in PEX, including the eyelid skin, lacrimal gland, conjunctiva, orbital fat and vessels, as well as the optic nerve, has been reported by several previous studies. The peri-ocular effects of PEX include the development of eyelid laxity, conjunctival chalasis, tear film abnormalities, pronounced orbital fat atrophy in response to the administration of prostaglandin analogues in pseudoexfoliative glaucoma, deficient orbital vascular supply and biomechanical changes in both the eyeball and the optic nerve.
