[Contact lens-associated Paecilomyces lilacinus keratitis]. / Kontaktlinsenassoziierte Paecilomyces-lilacinus-Keratitis.

We present the case of a 23-year-old otherwise healthy female patient with contact lens-associated Paecilomyces lilacinus keratitis. The clinical findings stabilized after initial local antimycotic and antibacterial treatment; however, in the further course of local therapy an extensive relapse occurred which required treatment by perforating keratoplasty à chaud due to a penetrating corneal ulcer. The patient responded well to subsequent treatment with systemic and local antimycotic medication. After a few months HLA-matched keratoplasty was performed. During the follow-up time of 14 months there were no signs of recurrence of the infection.

[Traumatic Lacrimal Duct Stenosis: Demographics and Success Rate of Surgical Procedures for Secondary Treatment]. / Traumatische Tränenwegsstenosen: Epidemiologie und Erfolgsraten nach sekundärer operativer Intervention.

BACKGROUND: Traumatic lacrimal duct stenosis can be the result of sharp trauma of the eyelid, indirect trauma or surgery in the nasoorbital region, as well as burns, chemotherapy and radiation of the facial region. The aim of the study is to present the demographics, patient satisfaction, and course of different surgical procedures for secondary treatment of traumatic lacrimal duct stenosis. METHODS: We retrospectively reviewed the medical records of 50 patients who required surgery for traumatic lacrimal duct stenosis from 2009 to 2011 at the University Eye Hospital in Muenster. The evaluation included the following criteria: age, sex, duration of symptoms, complication rate and the rate of recurrence. We systematically evaluated the medical data and asked the patients about the recent symptoms via telephone questionnaire. RESULTS: 60 eyes of 50 patients were included (18 women; 32 men; age: 51.8 ± 17.1 years); 34 eyes (56.7 %) had already had operations of the lacrimal system. The success rate was 58.1 %. The mean postoperative follow-up was 52.3 ± 10.7 months. In 11 cases (18.3 %), a dakryocystorhinostomy (DCR) was necessary. CONCLUSION: Traumatic lacrimal stenosis is more common in men, and has a poorer prognosis than lacrimal duct stenosis from other causes.

[Microsurgical Treatment of Canalicular Stenosis: Long-Term Follow-Up]. / Verlauf von Kanalikulusstenosen nach mikroskopischer Kanalikuluschirurgie.

PURPOSE: Studies about the indication and the functional prognosis of microsurgical treatment of canalicular stenosis (CR) are rare. In this study we determined the cause, recurrence and success rates of CR and compared our results with the results in the literature. METHODS: We retrospectively reviewed the medical records of 22 patients who required a microsurgical treatment of canalicular stenosis (CR) from 2009 to 2011. We systematically evaluated the medical data and asked the patients about the recent symptoms via telephone questionnaire. RESULTS: 22 patients were included (73 % women; 27 % men; age: 52.8 ± 19.9 years), 12 (55 %) patients had already had operations. The mean postoperative follow-up was 45 ± 9.2 months. The patients were followed for a minimum of 30 months. The success rate was 58 %. CONCLUSION: In some cases like long localised canalicular stenosis and especially after traumatic lacerations of the lacrimal canaliculi, a microsurgical treatment of canalicular stenosis is required. The aim of this procedure is to restore the lacrimal mucosa continuity so that a spontaneous lacrimal drainage is possible. The success rate of CR in our study was 58 %.

[The German Acanthamoeba keratitis register: Initial results of a multicenter study]. / Das Deutsche Akanthamöbenkeratitis-Register : Erste Ergebnisse einer multizentrischen Erhebung.

BACKGROUND AND PURPOSE: In September 2011 the cornea section of the German Ophthalmological Society (DOG) established the first German Acanthamoeba keratitis registry. The data of this multicenter survey are being collected, compiled and evaluated at the Department of Ophthalmology at the Saarland University. The aim of this article is to present an intermediate report. PATIENTS AND METHODS: Data from 172 eyes with Acanthamoeba keratitis were collected during the last 10 years. For this interim report we actually evaluated 121 eyes (60.2 % female patients, average age 41.3 years) and collected the following data: date of onset of symptoms, date and method of diagnosis, initial diagnosis, anamnestic data, clinical symptoms and signs at diagnosis and during follow-up, conservative and surgical therapy. Criteria for inclusion in the Acanthamoeba registry was the established diagnosis of an Acanthamoeba keratitis with at least one of the methods described in this article. RESULTS: Acanthamoeba keratitis could be histologically proven in 55.3 % of the cases, via PCR in 25.6 %, with confocal microscopy in 20.4 % and using in vitro cultivation in 15.5 %. Clinical symptoms and signs in Acanthamoeba keratitis were pain in 67.0 %, ring infiltrates in 53.4 %, pseudodendritiform epitheliopathy in 11.7 % and keratoneuritis in 5.8 %. In 47.6 % of the cases the initial diagnosis was herpes simplex virus keratitis followed by bacterial keratitis in 25.2 % and fungal keratitis in 3.9 %. Acanthamoeba keratitis was the correct initial diagnosis in only 23.2 % of cases. The average time period between first symptoms and diagnosis was 2.8 ± 4.0 months (range 0-23 months). A triple therapy with Brolene® Lavasept® and antibiotic eye drops at least 5 ×/day was used in 54.5 % of eyes (n = 66). Penetrating keratoplasty was performed in 40.4 %, in 18 cases in combination with cryotherapy of the cornea. The mean graft diameter was 7.9 ± 1.1 mm (range 3.5-11.0 mm). The final visual acuity (Snellen visual acuity chart at 5 m) was comparable in the two groups of eyes with (5/40 ± 5/25) and without (5/32 ± 5/25) keratoplasty. CONCLUSION: Acanthamoeba keratitis is a rare and often very late diagnosed disease and two thirds of the cases were initially misdiagnosed. The early recognition of the typical symptoms is crucial for the prognosis of the disease. All ophthalmological departments in Germany are invited to submit further data of all confirmed cases (berthold.seitz@uks.eu), whether retrospectively or prospectively in order to generate an adequate standardized diagnostic and therapeutic approach for this potentially devastating disease.
