Traumatische Tränenwegsstenosen: Epidemiologie und Erfolgsraten nach sekundärer operativer Intervention

Klinische Monatsblätter für Augenheilkunde (2015)

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.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.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.Traumatic lacrimal stenosis is more common in men, and has a poorer prognosis than lacrimal duct stenosis from other causes.

Corneal Densitometry, Central Corneal Thickness, and Corneal Central-to-Peripheral Thickness Ratio in Patients With Fuchs Endothelial Dystrophy

Cornea (2015)

Maged Alnawaiseh Lars Zumhagen G. Wirths Maria Eveslage Nicole Eter

Purpose: The aim of the study was to quantify Scheimpflug corneal densitometry in patients with Fuchs endothelial dystrophy (FED). Methods: In this study, we retrospectively reviewed the charts and anterior segment data of 49 patients with FED before posterior lamellar keratoplasty and 51 healthy controls. The patients were examined using the Scheimpflug-based Oculus Pentacam. Central corneal thickness (CCT), ring-averaged (on a circle of 2, 2.4–10 mm diameter) noncentral corneal thickness, and densitometry data in different corneal layers and in different annuli were extracted and analyzed. Results: The total corneal light backscatter at total corneal thickness (CT) and at total diameter was significantly higher in the FED group when compared with the control group (FED group: 28.8 ± 6.7; control group: 24.3 ± 4.1; P < 0.001). When the corneal surface was divided into concentric annular zones at total CT, the differences were significant only in the 2 central annuli (P < 0.001). The total corneal light backscatter at total CT in the central 0–2 mm annulus correlated moderately with the central corneal thickness (Pearson's correlation = 0.55, P < 0.001). Conclusions: Corneal light backscatter in the central cornea was greater in patients with FED than in normal subjects. Corneal densitometry enables us to evaluate the optical quality of the cornea in different corneal layers and in different annuli. It is a useful, objective method that, in combination with central corneal thickness and corneal central-to-peripheral thickness ratio, can help to quantify FED severity.

Optical coherence tomography (OCT) angiography findings in retinal arterial macroaneurysms

BMC Ophthalmology (2016)

Maged Alnawaiseh Friederike Schubert Pieter Nelis G. Wirths André Rosentreter

Optical coherence tomography angiography is a novel imaging technique that allows dyeless in vivo visualization of the retinal and choroidal vasculature. The purpose of this study was to describe optical coherence tomography (OCT) angiography findings in patients with retinal arterial macroaneurysms (RAMs). Three eyes of three patients with RAMs were retrospectively included. Fundus photography, OCT, fluorescein angiography (FA), and OCT angiography were performed. The entire imaging data was analyzed in detail. OCT angiography could detect the RAMs noninvasively without dye injection. By simultaneously observing the OCT scans, it was possible to determine the depth of the RAMs in the retina, to detect the exact localization in relation to the main vessel, and to determine the level of blood flow in the RAMs. OCT angiography can clearly visualize RAMs without use of a dye. It also allows layer-specific observation of blood flow in each layer of the RAM. OCT angiography provides additional dynamic information on RAMs, which is not obtained with FA and facilitates a better understanding of its morphology and activity. This information in combination with ICG and fluorescein angiography can help to optimize direct laser treatment.
