“…However, END-DCR has some advantages over EXT-DCR such as limited invasiveness, shorter operative time, preservation of pump function, less bleeding, and absence of skin trauma that can lead to an external scar. 1 Recently, Ng et al 32 described a new surgical EXT-DCR technique in which the external cutaneous scar can be avoided, thanks to a periciliary incision, making the procedure more aesthetically desirable, with a functional success rate of 83.3%. Similar aesthetic external surgical approaches have been proposed by other authors with variable results.…”

Introduction: Endoscopic dacryocystorhinostomy is a well-known surgical practice used to treat nasolacrimal duct obstruction and widely considered as a valid alternative to external approaches. Purpose: We present a retrospective case series of 498 endoscopic dacryocystorhinostomies on 401 patients, from July 2004 to May 2018, at the Department of Otolaryngology, San Raffaele Hospital, Milan, Italy. Methods: Of the 498 procedures, 426 were unilateral and 72 were bilateral dacryocystorhinostomy. All patients underwent routine preoperative workup including fluorescein test (Jones test 1–2), probing and irrigation of the lacrimal way, nasal endoscopy, and maxilla-facial computed tomography scan. Surgical technique was based on nasal endoscopic dacryocystorhinostomy followed by positioning of a Catalano’s silicone stent, which was left in place for about 3 months. Anatomical success was defined as a patent ostium on irrigation, whereas functional success was defined as free lacrimal flow on functional test and resolution of epiphora. Results: Anatomic success was achieved in 91.54% cases in primary dacryocystorhinostomy and in 89.36% after revision, whereas functional success was obtained in 90.4% in primary and 85.1% in secondary dacryocystorhinostomies. After a second revision of endoscopic dacryocystorhinostomy, anatomical success was achieved in 90.1% and functional success in 88.7% of procedures. Conclusion: Our results confirm that endoscopic dacryocystorhinostomy can be considered as a valid surgical approach to primary nasolacrimal duct obstruction and revision cases. The key aspects in achieving functional and anatomical results are meticulous surgical procedure and precise follow-up.

“…The total protein concentration (TPC) of tear fluids is 7-fold lower than that of blood serum. 15 Therefore, highly sensitive molecular techniques including immunoassays, 16 electrophoresis, 17 and mass spectrometry 18 can be useful in tear fluid analysis. However, only small volumes of tear fluids can be obtained from normal, nonirritated eyes.…”

Label-Free Biochemical Analytic Method for the Early Detection of Adenoviral Conjunctivitis Using Human Tear Biofluids

et al. 2014

Cell culture and polymerase chain reaction are currently regarded as the gold standard for adenoviral conjunctivitis diagnosis. They maximize sensitivity and specificity but require several days to 3 weeks to get the results. The aim of this study is to determine the potential of Raman spectroscopy as a stand-alone analytical tool for clinical diagnosis of adenoviral conjunctivitis using human tear fluids. A drop-coating deposition surface enhanced Raman scattering (DCD-SERS) method was identified as the most effective method of proteomic analysis in tear biofluids. The proposed DCD-SERS method (using a 2-μL sample) led to Raman spectra with high reproducibility, noise-independence, and uniformity. Additionally, the spectra were independent of the volume of biofluids used and detection zones, including the ring, middle, and central zone, with the exception of the outer layer of the ring zone. Assessments with an intensity ratio of 1242-1342 cm(-1) achieved 100% sensitivity and 100% specificity in the central zone. Principal component analysis assessments achieved 0.9453 in the area under the receiver operating characteristic curve (AUC) as well as 93.3% sensitivity and 94.5% specificity in the central zone. Multi-Gaussian peak assessments showed that the differences between these two groups resulted from the reduction of the amide III α-helix structures of the proteins. The presence of adenovirus in tear fluids could be detected more accurately in the center of the sample than in the periphery. The DCD-SERS technique allowed for high chemical structure sensitivity without additional tagging or chemical modification, making it a good alternative for early clinical diagnosis of adenoviral conjunctivitis. Therefore, we are hopeful that the DCD-SERS method will be approved for use in ophthalmological clinics in the near future.

“…20 Some surgeons elect to apply topical mitomycin-C to the intranasal rhinostomy site. 8 Mitomycin-C is an antimetabolite that inhibits fibroblast function and has been used to modulate postsurgical fibrosis in a variety of applications. 17 However reports on the utility of mitomycin-C in prevention of postoperative mucosal fibrosis and rhinostomy closure have demonstrated mixed results.…”

“…steeper learning curve. 8 Endonasal techniques were also limited because they provided poor visualization of the lacrimal sac in the superior nasal cavity and lacked effective instrumentation to adequately open the sac. 15 This may result from fibrous occlusion of the rhinostomy site or the presence of synechiae between the lateral nasal wall and middle turbinate or nasal septum.…”

Background: Study conducted to know surgical outcome of combined endoscopic endonasal and subciliary approach in revision DCR cases and complications associated with the procedure.Methods: Prospective, single-blinded, randomized, interventional study is carried out in Tertiary level center from August 2009 to April 2016. Totally 18 patients (11 female and 7 male) were involved in the study who has undergone previous DCR (11 external DCR and 7 endoscopic DCR). The results were analyzed at end of the 3rd and 6th month both subjectively and objectively. Results: All the 18 patients who underwent combined approach were relived from epiphora. None of the patients developed any complications following surgery.Conclusions: The combination of endoscopic and external approach gives benefits of the both approaches giving huge advantages in revision cases. It gives excellent visualization of the surgical field, ability to correct internal nasal pathologies, make clear rhinostoma, workprecisely on fibrosed lacrimal sac and nearly no external scar. It provides good team work opportunity between otorhinologist and ophthalmologist.
