On average, esotropia and ductions tend to worsen with decompression surgery. This result supports the clinical dictum to avoid strabismus surgery until after decompression. The improvement in lower eyelid retraction suggests that at least lower eyelid-lengthening surgery should be reserved for after decompression, as there may be significant spontaneous improvement, while the same may not be true for upper eyelid retraction, which does not tend to change with decompression.
Objective. To compare pre- and postoperative characteristics and surgical success rates of patients with and without previous episodes of dacryocystitis, who underwent external dacryocystorhinostomy (DCR) for nasolacrimal duct obstruction (NLDO). Methods. The medical files of all patients who underwent external DCR between 2006 and 2011 in our institution were reviewed. The retrieved data of patients with and without previous episodes of dacryocystitis were compared. Surgical success was determined by postoperative followup of at least 6 months. Results. A total of 185 patients with NLDO underwent external DCR of whom 152 (100 females and 52 males, mean age 67 ± 15 years) met the inclusion criteria. Sixty had previous episodes of dacryocystitis and 92 did not. Left-side obstruction was more common than right-side obstruction among patients with previous episodes of dacryocystitis (48.3% versus 31.7%, resp., P = 0.031). Glaucoma patients were significantly more likely to develop dacryocystitis than patients without glaucoma (P = 0.002). The success rate of external DCR was 94.4% for patients with previous episodes of dacryocystitis and 86.7% for patients without (P = 0.337). Conclusions. The surgical outcomes of external DCR in patients with or without a previous episode of dacryocystitis were similar. Patients with glaucoma and NLDO had a significantly higher risk of developing dacryocystitis.
The leading etiology of endophthalmitis changed from postoperative endophthalmitis to endophthalmitis after IVT injection from 2003 to 2010, and the incidence of the infection as a complication of those procedures decreased.
To our knowledge, this is the first study to describe the correlation of anterior chamber bleeding after laser peripheral iridotomy (LPI) and antiplatelet therapy.Objective: To determine the incidence and amount of anterior chamber bleeding after laser peripheral iridotomy in patients whose condition is suggestive of primary angle-closure glaucoma (PACS) who continued their antiplatelet or anticoagulant treatment before undergoing LPI compared with when they discontinued treatment.Design and Setting: A prospective controlled trial.Patients: Patients with suspected bilateral primary angleclosure and no other ocular disease who take antiplatelet or anticoagulant medications regularly (from January 2010-October 2011) were enrolled.Main Outcome and Measure: The incidence of anterior chamber bleeding with and without antiplatelet and anticoagulant therapy.Results: A total of 104 patients (208 eyes) participated in the study. Thirty-six eyes (34.6%) in the treated and untreated arms bled. The amount of bleeding did not differ significantly when the patient was on or off antiplatelet or anticoagulant treatment, nor did the immediate postprocedure mean intraocular pressure (P =.13). The type of antiplatelet or anticoagulant, total laser energy, age, sex, or color of irides were not risk factors for increased bleeding (P=.156 for all parameters).
Conclusions:No indication was noted for discontinuing these medications before a high-powered pulsed laser peripheral iridotomy.

The objective of this study is to describe a series of patients with different pathologies mimicking nasolacrimal duct obstruction (NLDO), diagnosed with the use of a computed tomography (CT) scan prior to a scheduled endoscopic dacryocystorhinostomy (DCR). This study is a retrospective report. We reviewed the medical records of 47 consecutive patients (57 sides) with long-standing epiphora between 2007 and 2012. All patients were referred to our tertiary Medical Center with a diagnosis of NLDO and were expected to undergo endoscopic dacryocystorhinostomy (DCR). They all underwent routine sinus CT scan prior to surgery. All scans, as well as the demographic and medical characteristics of these patients were reviewed. Of all 47 patients enrolled, in 4 patients (7 % of all sides), unexpected pathologies, other than nasolacrimal system distention, inflammation or infection were identified preoperatively. These included squamous cell carcinoma of the lacrimal sac and nasolacrimal duct, rhinoscleroma at Hasner's valve region, a compressing ethmoidal mucocele and a case of dacryocystocele. These unusual pathologies mandated a different management and surgical approach. In all four cases, a preoperative CT scan helped in identifying the pathology and in localizing the lacrimal apparatus in relation to the paranasal sinuses. Different nasal, paranasal and lacrimal pathologies may mimic primary acquired NLDO. A high index of suspicion, a thorough clinical evaluation and utilizing preoperative imaging may lead to an alteration of patient management and to a completely different surgical approach.
We compared the intraocular pressure (IOP)-lowering effect and safety profile of latanoprost (Xalatan) with its generic variant, Glautan (Unipharm, Tel Aviv, Israel). After 1 and 4 weeks of treatment, a randomized, prospective, cross-over comparison was carried out that included patients with open-angle glaucoma or ocular hypertension, either naïve or treated and well-controlled, who were attending the Department of Ophthalmology, Tel Aviv Medical Centre, Tel Aviv, Israel, between May 2010 and November 2012. After a 3-week washout period for the medicated subjects, the participants were randomized to 4 weeks of treatment with either Xalatan or Glautan once every evening and then, after a 3-week washout period, crossed-over to the other treatment for an additional 4 weeks. Efficacy was expressed by a change in intraocular pressure at three designated hours of the day after 1 week and 1 month of treatment, and tolerability was determined by ocular side-effects as reported by the patient in a questionnaire. A total of 19 patients (mean age at initial diagnosis 66 ± 9 years, 14 females) were enrolled, of whom 17 had bilateral open-angle glaucoma and two had unilateral disease. Both drugs lowered intraocular pressure after 1 week and 1 month (P = 0.06 and P = 0.04, respectively) of treatment. Xalatan had a tendency of greater efficacy than Glautan both after 1 week and 1 month, but the difference was not statistically significant (P = 0.69 and P = 0.34, respectively). Drug safety was similar for Xalatan or Glautan, but more ocular side-effects were reported after treatment with Glautan (21 vs 12 for Xalatan, P = 0.06).
