Giant secondary conjunctival inclusion cysts: a late complication of strabismus surgery.

Purpose: To present giant conjunctival inclusion cysts as a late complication of strabismus surgery.

Design: Retrospective case series of selected patients.

Participants: Four patients with a history of strabismus surgery who had developed giant conjunctival inclusion cysts.

High-frequency ultrasound of anterior segment retinoblastoma.

Purpose: To evaluate anterior segment retinoblastoma with high-frequency ultrasound.

Design: Interventional case report.

Methods: An 11-year-old boy with a total retinal detachment and multiple white anterior chamber nodules was examined with high-frequency ultrasound before enucleation of the globe.

Retinal artery embolization: a rare presentation of calcific aortic stenosis.

Retinal artery embolization is an unusual but serious complication of calcific aortic stenosis. However, it is rare for retinal embolization to be the presenting feature of aortic stenosis. This report describes a young patient who presented with an acute retinal artery occlusion secondary to calcific aortic valve disease, and discusses the rationale for early surgical intervention.

Origin of the foveal granular pattern in entoptic viewing.

Purpose: To investigate the controversial origin of the foveal granular pattern at the center of the entoptic Purkinje vessel shadows. Both phenomena may be vividly elicited by oscillating a focused spot of light across the scleral surface of the eye in a circumferential direction.

Methods: The site and pattern of oscillation of the light spot were varied and were correlated with the appearance of the foveal granular pattern.

Deteriorated accommodative esotropia.

Deteriorated accommodative esotropia is a residual esotropia with treatment in previously controlled esotropia. Hypothesized etiologies include occlusion, undercorrected hyperopia, increased AC/A ratio, increased or undetected hyperopia, microtropia, delay in treatment and poor compliance.

A comparison of the success rates of resident and attending strabismus surgery.

Residency training involves surgery by resident surgeons at various levels of experience and proficiency, supervised by an experienced attending physician. We reviewed the results of strabismus surgery performed at four institutions with two residency training programs. Five hundred twenty-two cases with follow up greater than 6 weeks were evaluated.

Rapid determination of intraocular lens tilt and decentration through the undilated pupil.

The apparent optical axis of an implanted intraocular lens (IOL) can be located by alignment of the examiner's hand light with the third and fourth Purkinje images from the front and back surfaces of the IOL. Tilt of the IOL can be estimated (or measured with an arc perimeter) by the angle between the apparent optical axis and the patient's line of sight (actual tilt approximately 0.85 x apparent tilt).

Standardization of computer systems for logging operative cases.

With the advent of extremely rapid, powerful, compact, and inexpensive microcomputers, a revolution in data manipulation is ongoing. We have customized and used for over two years prepackaged software to track residents' operative experiences in the Department of Otolaryngology at Jefferson Medical College of Thomas Jefferson University, Philadelphia. An attempt is presently being made to develop a similar system that might be utilized by all otolaryngology teaching programs and thus enable the collection and review of residents' operative experiences nationally.

Reoperation rate in adjustable strabismus surgery.

Adjustable suture strabismus surgery may reduce the frequency of reoperations by reducing immediate postoperative over- and undercorrections. We reviewed 290 strabismus procedures performed with an adjustable suture technique. Thirty-five patients required additional surgery, for a reoperation rate of 9.

The Wilmer Information System. A classification and retrieval system for information on diagnosis and therapy in ophthalmology.

The Wilmer Information System is a computerized medical information system used for the storage and retrieval of data pertaining to patient demographics, diagnosis, and therapy. The heart of the system is an expandable, hierarchical code based on International Classification of Diseases, 9th Revision (ICD-9) diagnosis codes and Physicians' Current Procedural Terminology procedure codes. Customized coding sheets containing highly specific diagnosis and procedure codes have been designed for each subspecialty area in ophthalmology.

Freezing increment in keratophakia.

In homoplastic keratomileusis, keratophakia, and epikeratophakia, the corneal tissue that provides the final refractive lenticule undergoes a conformational change when frozen. Because corneal tissue is composed primarily of water, an assumed value of 9.08% (approximate volumic percentage expansion of water when frozen) is frequently used for the increase in thickness, or freezing increment, rather than measuring it directly.
