RESUMEN
A new technique for retrieval or repositioning of migrated or malpositioned silicone punctal plugs is described. Malposition is known to occur secondary to either spontaneous migration or forceful insertion. This technique offers considerable advantages over current treatment options including simplicity and minimal trauma to both the plug and the nasolacrimal system.

PURPOSE: To photographically document venous collateral development, remodeling, and regression in a patient with traumatic glaucoma. METHODS: Consecutive fundus photographs were evaluated, labeled, and correlated with the clinical history of a patient with unilateral posttraumatic glaucoma. RESULTS: This report photographically documents the appearance, remodeling, and subsequent disappearance of collateral vessels from venous occlusion on the surface of the optic disk in an eye with increased intraocular pressure and progressive glaucomatous cupping. CONCLUSIONS: Asymptomatic chronic obstruction of a branch retinal vein on the optic disk may cause venous collaterals to develop in the absence of retinal hemorrhages or other signs of venous occlusive disease. Increased intraocular pressure, arteriolarsclerosis, and glaucomatous cupping are risk factors for these occlusions.

An 80-year-old monocular man with long-standing primary open angle glaucoma underwent successful filtering surgery in his sighted right eye in 1980. He subsequently developed a cataract and had an uncomplicated clear cornea phacoemulsification with posterior chamber intraocular lens in 1996. Post-operatively, the filtration bleb remained very avascular but shallowed; the intraocular pressure increased and remained uncontrolled despite maximally tolerated medical therapy. His vision improved to 6/7.5 and automated perimetry revealed a less than 5 degrees small central island of vision. His left eye was phthisical with no light perception.

Patients who suffer from epiphora can benefit from reconstructive surgery in many cases of obstructive and nonobstructive lesions of the lacrimal apparatus. We describe our technique of digital subtraction macrodacryocystography (DSM) and discuss its efficacy in the evaluation of various abnormalities involving the lacrimal drainage pathway. A variety of pathologic conditions of the lacrimal apparatus are portrayed. DSM is an accurate, easy to perform, but relatively unrecognized method of anatomic localization of obstructive lesions within the lacrimal drainage system.
