Orbit, 2012
A right orbit was exenterated from a male cadaver that was 85 years of age at death. It was microscopically shown for the first time that the lacrimal sac septum divided the lumen into two spaces. It consisted of fibrous tissue with a cavernous structure and was lined with stratified columnar epithelium similar to the lacrimal sac wall.

Color Doppler Imaging Features of the Lacrimal Sac in Health and Diseased States
Current Eye Research, 2020Purpose The objective of this study is to present Color Doppler imaging (CDI) features of the lacrimal sac in normal and diseased states. Methods Prospective study was performed on 20 lacrimal sacs of 20 eyes of 10 patients who underwent Color Doppler ...

This is a clinicopathologic study of 115 lacrimal sac neoplasms in adults (mean 52 years). The most common presenting signs and symptoms were epiphora (53%), recurrent dacryocystitis (38%), and/or lacrimal sac mass (36%). The tumors were divided into epithelial (82 cases) and nonepithelial (33 cases) neoplasms.

Poorly differentiated primary adenocarcinoma of the lacrimal sac and the nasolacrimal duct
Orbit, 2020Primary adenocarcinoma of the lacrimal drainage system is a rare malignancy. Poorly differentiated subtypes of this tumor demonstrate aggressive behaviors, and metastasis is not uncommon.

This report details the presentation, workup, and treatment of the largest lacrimal duct cyst ever reported in the ophthalmic literature. Included in this report is the first computed tomographic (CT) image of this unusual lesion. Typical and atypical clinical features of this lacrimal sac cyst are emphasized.

Silver deposition in the wall of the lacrimal sac after prolonged application of mild silver protein (Argyrol) eye drops is documented at the light and electron microscopical level. Silver granules were found in the extracellular matrix predominantly on elastic fibres and within cells forming conglomerates in secondary lysosomes.
