Scanning Electron Microscopic Features of Extubated Monoka Stents.

Purpose: The aim of this study was to examine the presence of surface and intraluminal biofilms and physical deposits on the extubated Monoka stents.

Methods: A prospective interventional study was performed on consecutive patients who underwent Monoka stents placement for varied indications. The patient samples were retrieved either at 6 weeks or 3 months after the surgery based on the indication for stent use.

Histopathology, Immunohistochemistry, and Electron Microscopic features of a Dacryocystorhinostomy Ostium Cicatrix.

Purpose: The aim of this study is to report the histopathological, Immunohistochemical, and ultrastructural features of a dacryocystorhinostomy ostium cicatrix.

Methods: A prospective histopathological study was performed in a tertiary eye care setting. Scarred nasal mucosal tissues obtained during endoscopic revisions of 10 previously failed dacryocystorhinostomies secondary to complete cicatricial closure of the ostia were studied.

Scanning Electron Microscopic Features of the External and Internal Surfaces of Normal Adult Lacrimal Drainage System.

Aim: The aim of this study was to examine the ultrastructural features of the external and internal surfaces of healthy lacrimal drainage systems.

Methods: A prospective interventional study was performed on the healthy adult lacrimal drainage systems obtained from fresh exenterated specimens. Exenteration was performed for malignancies unrelated to lacrimal system where preoperative lacrimal evaluation was normal.

Electron Microscopic Features of Intraluminal Portion of Nasolacrimal Silastic Stents Following Dacryocystorhinostomy: Is There a Need for Stents Without a Lumen?

Aim: The aim of this study was to examine the presence of biofilms and physical deposits within the lumen of silastic nasolacrimal duct stents inserted during dacryocystorhinostomy.

Methods: A prospective interventional study was performed on consecutive patients undergoing endoscopic dacryocystorhinostomy with Crawford stent insertion. All the patient samples were retrieved 4 weeks after the surgery.

Scanning Electron Microscopic Features of Nasolacrimal Silastic Stents Retained for Prolong Durations Following Dacryocystorhinostomy.

Purpose: The aims of this study were to examine the scanning electron microscopic features of silastic nasolacrimal duct stents retained for long durations following a dacryocystorhinostomy.

Methods: A prospective interventional study was performed on stents retrieved from patients who were lost to follow up after a dacryocystorhinostomy with Crawford stent insertion. Long duration was defined as stents retrieved at a minimum of 1 year following a dacryocystorhinostomy.

Biofilms and Physical Deposits on Nasolacrimal Silastic Stents Following Dacryocystorhinostomy: Is There a Difference Between Ocular and Nasal Segments?

Purpose: The aims of this study were to examine the presence of biofilms and physical deposits on ocular and nasal segments of silastic nasolacrimal duct stents inserted after dacryocystorhinostomy and to document any differences.

Methods: A prospective interventional study was performed on a series of patients undergoing dacryocystorhinostomy with Crawford stent insertion. All the patient samples were retrieved 4 weeks after an endoscopic dacryocystorhinostomy.

Electron microscopic features of nasal mucosa treated with topical and circumostial injection of mitomycin C: implications in dacryocystorhinostomy.

Purpose: To evaluate the ultrastructural effects of topical and circumostial injection of mitomycin C (COS-MMC) on nasal mucosa and compare them with the controls. The study also aimed at classifying the subcellular effects in detail.

Methods: The nasal mucosa of 6 patients were subjected to 0.

Punctal stenosis: histopathology, immunology, and electron microscopic features-a step toward unraveling the mysterious etiopathogenesis.

Purpose: To study the histologic, immunohistochemical, and electron microscopic features of puncta and proximal vertical canaliculi to understand the etiopathogenesis of punctal stenosis.

Methods: Prospective study of 26 stenosed punctae that were collected following a punctoplasty. Sixteen were from lower eyelid and 10 from upper eyelid.
