Diplopia and strabismus following ocular surgeries.

Postoperative diplopia and strabismus may result from a variety of ocular surgical procedures. Common underlying mechanisms include sensory disturbance, scarring, direct extraocular muscle injury, myotoxicity from injections of local anesthesia or antibiotics, and malpositioning of extraocular muscles by implant materials. The most common patterns are vertical and horizontal motility disturbance.

Characterizing pseudoexfoliation syndrome through the use of ultrasound biomicroscopy.

Purpose: To determine the clinical utility of ultrasound biomicroscopy (UBM) in diagnosis of pseudoexfoliation (PEX) syndrome by characterizing the lens capsule and zonules before cataract surgery.

Setting: Veterans Administration Hospital, East Orange, and University of Medicine & Dentistry of New Jersey-New Jersey Medical School, Newark, New Jersey, USA.

Methods: Ultrasound biomicroscopy was performed on 10 patients clinically diagnosed with PEX syndrome.

Cataract surgery in the small adult eye.

Microphthalmos is a rare condition that is often associated with several other ocular abnormalities. Given the considerable differences between microphthalmic and anatomically normal eyes, cataract surgery is technically demanding in these patients, and special attention must be given to adequate preoperative planning of these procedures. Furthermore, the unique nature of these surgeries creates a particular subset of intraoperative and postoperative complications.
