    ABSTRACT: Purpose: To evaluate the efficacy of a sleeve technique during endoscopic dacryocystorhinostomy (DCR) in primary nasolacrimal duct obstruction (NLDO) patients with a high lacrimal sac. Materials and Methods: The medical records of 45 patients (49 cases) undergoing endoscopic DCR for primary NLDO with a high lacrimal sac were retrospectively reviewed. In 19 patients (21 cases), the thick maxilla covering the common canalicular opening was removed using a drill and a bicanalicular silicone tube was inserted (group 1). In 26 patients (28 cases), instead of removal of the thick maxilla, a sleeve was inserted into the bicanalicular silicone tube (group 2). At 6 months postoperatively, the success rate was evaluated and the size of the intranasal mucosal ostium was measured. Results: The success rates in group 1 and 2 was 90.5% and 96.4%, respectively (P =0.400). The intranasal mucosal ostium in group 1 and 2 measured 1.7 ± 0.7 mm and 3.1 ± 1.0 mm, respectively, and the difference was significant (P =0.042). Conclusions: In primary NLDO patients with a high lacrimal sac, DCR inserting a silicone tube and a sleeve together had a satisfactory success rate without using a drill. In comparison with traditional surgical methods, it helped enlarge the size of the intranasal mucosal ostium.

    ABSTRACT: The cause of central serous chorioretinopathy (CSC) is mostly idiopathic. Other cause such as stressful event or use of corticosteroid has been associated with severe form of CSC. Atypical presentation of CSC has widespread degeneration of retinal pigment epithelium (RPE) or bullous retinal detachment. In this report, we describe a case of bilateral CSC with RPE tear after epidural steroid injection.

    ABSTRACT: The authors report a caruncular abscess caused by actinomycosis. A 47-year-old woman was admitted with persistent purulent discharge from the caruncle of the left eye for a duration of six months. Excisional drainage was performed, and 'sulfur granules' were observed, consistent with actinomyces infection. Intraoperative lacrimal probing and irrigation were performed to confirm that the abscess and canaliculus were not connected. Oral and topical antibiotics were administered postoperatively; the lesion resolved with no evidence of recurrence, and the symptom improved.

    ABSTRACT: Duane syndrome is a dysinnervation disorder that frequently involves secondary anomalous eye movement, in particular, ocular retraction and the narrowing of the palpebral fissure on the adduction. Pseudo-Duane syndrome is caused by a mechanical restriction that produces clinical findings similar to those of Duane syndrome. Most patients with pseudo-Duane syndrome have restrictive pathologies on the medial side of the globe, such as entrapment of the medial rectus muscle. We report the case of a 44-year-old man with pseudo-Duane syndrome in whom we identified a lateral orbital wall fracture and entrapment of the soft tissue surrounding the lateral rectus muscle by computed tomography. To the best of our knowledge, this etiology of pseudo-Duane syndrome has not been previously reported.

    ABSTRACT: A mass that recurred after dacryocystectomy for benign squamous papilloma of the lacrimal sac was diagnosed as a high-grade mucoepidermoid carcinoma in a 53-year-old man on histopathology. Local excision to the orbital periosteum was performed and gave a margin free of invasion. Neither local recurrence nor systemic metastasis was found 3 years after local excision. Mucoepidermoid carcinoma of the lacrimal sac is extremely rare and spreads locally in an aggressive manner; a cure typically requires exenteration, radical resection, or adjuvant radiotherapy. In this rare case, despite the high malignancy, the patient underwent successful local excision, achieved an aesthetically satisfying result, and has had a long-term cancer-free period.

    ABSTRACT: Currently, many surgeons use bicanalicular silicone tubes as a stent to keep the intranasal mucosal ostium patent when they perform endoscopic dacryocystorhinostomy. The authors describe the sleeve technique using bicanalicular silicone tubes. After inserting the bicanalicular silicone tube, a sleeve is passed over it. The sleeve prevents the nasal mucosa from obstructing the intranasal mucosal ostium and enlarges the mucosal ostium. In primary acquired nasolacrimal duct obstruction, the sleeve technique was applied to 61 cases (group 1); the other 75 cases (group 2) were intubated by bicanalicular silicone tube only. The overall success rate was 95.1% in group 1 and 90.7% in group 2 (P = .51), and the average mucosal ostium at 6 months postoperatively was 3.2 ± 1.1 and 1.9 ± 1.0 mm (P = .04), respectively. The authors believe that the sleeve technique has the advantage of maintaining a larger intranasal mucosal ostium.
