The effectiveness of simultaneous medial spindle and/or lateral tarsal strip procedure in East Asian patients who need endonasal dacryocystorhinostomy.

BACKGROUNDS: To evaluate the effectiveness of simultaneous medial spindle procedure (MS) and/or lateral tarsal strip procedure (TS) with an endonasal dacryocystorhinostomy (DCR) for treatment of involutional medial punctal ectropion, horizontal eyelid laxity, and nasolacrimal duct obstruction. METHODS: We conducted a retrospective, interventional study of DCR performed from March 2009 to July 2011 by a single surgeon (Baek SH). Patient age, sex, results of medial and lateral distraction test, surgical procedure, time of tube removal, duration of follow-up, functional and anatomical success rate, and causes of failed surgeries were recorded. Lateral lower eyelid laxity was evaluated by a medial distraction test, and medial lid laxity was evaluated by a lateral distraction test. RESULTS: A total of 241 eyes in 175 patients were included in this study. The proportion of combined surgeries to total DCR was 24.5% (59 of 241 eyes). DCR and MS (D + M) were performed on 23 eyes in 17 patients (9.5%) and DCR and TS (D + T) on 29 eyes in 17 patients (12.0%). Concurrent DCR, MS and TS (D + M + T) were performed on seven eyes in four patients (2.9%). Mean age was significantly higher in the combined surgery groups (63.8 ± 10.0 years) than in the DCR group (56.2 ± 10.6 years; p = 0.01, by Mann-Whitney U test). The anatomical success rates were 84.2% in D, 86.9% in D + M, 89.5% in D + T, and 85.7% in D + M + T (p = 0.61 by Kruskal-Wallis test). Functional success rates were 82.4% in D, 86.9% in D + M, 86.2% in D + T, and 85.7% in D + M + T (p = 0.91 by Kruskal-Wallis test). CONCLUSIONS: MS and TS performed concurrently with a DCR may be an effective tool to deal with epiphora due to complex clinical situations such as nasolacrimal duct obstruction, lid laxity, and involutional medial ectropion. It is recommended to examine punctum and lid laxity carefully using slit-lamp biomicroscopy and lid distraction test in patients with epiphora, especially in elderly patients.

Age-based comparison of successful probing in Nepalese children with nasolacrimal duct obstruction.

PURPOSE: To compare the success rates of probing in Nepalese children younger than 2 years versus children older than 2 years with nasolacrimal duct obstruction (NLDO), and to identify factors associated with successful probing. MATERIALS AND METHODS: Data was collected and analyzed retrospectively on children who underwent probing under general anesthesia for NLDO at Tilganga Eye Centre, Nepal, from May 2004 to October 2008. We compared successful probing rates in children less than or equal to 2 years old (group 1) versus children greater than 2 years old (group 2), and analyzed whether various clinical factors were associated with successful probing. Successful probing was defined as complete resolution of all clinical signs (discharge, epiphora or increased tear lake) at the outcome visit one month following surgery. RESULTS: Data on 84 children (109 eyes) was reviewed. The mean age of children in group 1 and group 2 was 15.3 months and 37.3 months, respectively. The success rate of probing for the overall sample was 82.6% (90/109 eyes). The success rate in group 1 was 90.2% (55/61 eyes), and 72.9% (35/48 eyes) in group 2 (p=0.018). Increased age at time of probing (p=0.031) and duration of symptoms (p=0.027) were associated with decreased probing success. CONCLUSION: Early treatment of NLDO with probing, ideally prior to 2 years, is associated with better outcomes. Age appropriate intervention may reduce the incidence of complications from NLDO, which is highly prevalent in the low-lying areas of Nepal, including Kathmandu.

The diameter of the nasolacrimal canal measured by computed tomography: gender and racial differences.

BACKGROUND: The incidence of dacryocystorhinostomy surgery among Pacific People is greater than would be expected given their proportion in the population. Some have suggested that racial and sex differences in facial skull dimensions produce narrower nasolacrimal canals and therefore differences in the incidence of primary acquired nasolacrimal duct obstruction (PANDO). We measured the minimum diameter of the canal in those not known to have PANDO. METHOD: A retrospective review of the digital computed tomography (CT) database was performed. Minimum diameter of the nasolacrimal canal on axial cuts of a sinus series CT scan was measured. Sex and racial origin were recorded. All series on the database were included. Absence of axial images and pathology distorting the canal excluded a patient. This was carried out in the Department of Radiology and Ophthalmology, Greenlane Medical Centre, Auckland. RESULTS: A total of 178 CT scans were included. Men had a mean diameter of 3.9 mm (95% confidence interval [95%CI]: 3.8-4.1) versus women 3.6 mm (95%CI: 3.5-3.8) P = 0.01. Both Caucasian and New Zealand Maori had mean diameters of 3.7 mm (95%CI: 3.5-3.9) whereas Pacific People were 4.1 mm (95%CI: 3.9-4.3) P = 0.01. CONCLUSIONS: As in other studies women had narrower canals than men. Surprisingly we found no difference between New Zealand Maori and Caucasian. Unexpected was the larger diameter in Pacific People, as they have a higher incidence of dacryocystorhinostomy surgery. PANDO is likely to be of multifactorial aetiology and nasolacrimal canal diameter may not be a significant factor. Our described method of measuring canal diameter by CT scan is comparable to a cadaver study.

Eyelid incision for dacryocystorhinostomy in Asians.

PURPOSE: Dacryocystorhinostomy via an eyelid incision has been described in Western literature. This study was undertaken to confirm that eyelid incision for dacryocystorhinostomy is suitable in Asians, because Asians have anatomic features that differ from those of Westerners. METHODS: We performed dacryocystorhinostomy with an eyelid incision along skin wrinkles or relaxed skin tension lines in 57 eyelids of 49 patients from July 2003 to December 2004. The medical records of the patients were reviewed retrospectively. RESULTS: Postoperative scars were easily camouflaged by wrinkles or relaxed skin tension lines of the eyelid without major complications. CONCLUSIONS: An eyelid incision can be used for dacryocystorhinostomy in Asians, regardless of the lack of a definite lower eyelid crease and the presence of epicanthus.
