Tear meniscus measurement in nasolacrimal duct obstruction patients with Fourier-domain optical coherence tomography: novel three-point capture method.
Summary of "Tear meniscus measurement in nasolacrimal duct obstruction patients with Fourier-domain optical coherence tomography: novel three-point capture method."
Purpose:  Fourier-domain optical coherence tomography (FD ODT) for the evaluation of marginal tear film has not been performed in patients with watery eye or in a controlled study. We used FD OCT to evaluate the height of the lower lid tear film at three points in normal adults and compared it with two watery eye groups. Methods:  We prospectively evaluated with FD OCT 25 normal subjects and 44 patients with a watery eye. Twenty-three patients with primary acquired nasolacrimal duct obstruction (PANDO) and 21 patients with functional nasolacrimal duct obstruction (FNLDO) were enrolled. Three images were obtained by three vertical FD OCT scans centred on the lower eyelid and inferior cornea, the medial limbus and the lateral limbus. The tear meniscus height (TMH), tear meniscus depth (TMD) and tear meniscus area (TMA) were measured with computer calipers and compared at three points between the two groups. Results:  Watery eyes have significantly greater median TMHs at three points (medial: 584 μm, central: 592 μm, lateral: 470 μm) than controls (274, 291, 205 μm, p < 0.001). Medial and central TMHs were higher than lateral TMH in controls and watery eyes. TMD and TMA also increased significantly in watery eyes (p < 0.001). There was a significant increase in central TMH compared to medial TMH in FNLDOs than in PANDOs (p < 0.05). Conclusion:  Fourier-domain OCT is a valuable clinical tool in the evaluation of TMH in normal and watery eyes. TMH at three points can be a useful clinical parameter that investigates changes of lower tear meniscus pattern in both PANDO and FNLDO groups.

Lacrimal Duct Obstruction
Interference with the secretion of tears by the lacrimal glands. Obstruction of the lacrimal sac or nasolacrimal duct causing acute or chronic inflammation of the lacrimal sac (DACRYOCYSTITIS). It is caused also in infants by failure of the nasolacrimal duct to open into the inferior meatus and occurs about the third week of life. In adults occlusion may occur spontaneously or after injury or nasal disease. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p250)
Dacryocystorhinostomy
Surgical fistulization of the lacrimal sac for external drainage of an obstructed nasolacrimal duct.
Lacrimal Apparatus
The tear-forming and tear-conducting system which includes the lacrimal glands, eyelid margins, conjunctival sac, and the tear drainage system.
Uterine Rupture
A complete separation or tear in the wall of the UTERUS with or without expulsion of the FETUS. It may be due to injuries, multiple pregnancies, large fetus, previous scarring, or obstruction.

Introduction: Acquired nasolacrimal duct obstruction is a common disorder affecting adults. Its pathogenesis is not known. We hypothesize that facial and bony asymmetry can contribute to the unilatera...
