Tear protein analysis in patients with primary acquired nasolacrimal duct obstruction treated with lacrimal passage intubation.

Purpose: The pathophysiology of nasolacrimal duct obstruction (NLDO) may involve quantitative as well as qualitative changes in tears. We measured tear protein concentrations in patients with primary acquired NLDO and compared them with the tear proteins in healthy individuals and patients with dry eye disease.

Study Design: Case-control study.

[Recent outcomes of vitreous surgery for diabetic retinopathy].

Purpose: To investigate background, surgical method, complications, prognosis, and prognostic factors in patients undergoing vitrectomy for diabetic retinopathy.

Subjects And Methods: Three hundred and forty eyes of 261 patients undergoing vitrectomy for diabetic retinopathy in five recent years were studied regarding background, surgical method, complications, and visual prognosis. Factors influencing postoperative visual acuity and complications were also examined using univariate and multivariate analyses.

Membranous proliferation on the posterior surface of an intraocular lens after Nd:YAG laser capsulotomy.

Background: We report on three patients who showed a rare complication, centripetal membranous proliferation from the posterior capsulotomy edge onto the posterior surface of an intraocular lens (IOL), 3 to 6 months after neodymium:YAG (Nd:YAG) capsulotomy.

Cases: These three patients had juvenile rheumatoid arthritis, retinitis pigmentosa, and sarcoidosis, respectively, prior to cataract surgery.

Observations: Elschnig's pearls developed in the eyes of all three patients after cataract surgery, and were treated by Nd:YAG laser.
