[Postoperative complications and management of filtration surgery.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Of the filtering procedures employed, trabeculectomy is the one most frequently used for surgical therapy in primary open angle glaucoma patients. Intra- and postoperative complications must be detected promptly and treated adequately. Many complications arise within the first weeks, such as bleb scaring, decreased flow beneath the scleral flap, extensive filtration with choroidal detachment and anterior chamber narrowing. Fibrin reaction, corneal dellen, iris prolapse, conjunctival leakage and ciliary body detachment are seen more rarely. With prophylactic pre- and perioperative application of antibiotics, wound infec...

[Effectiveness and relevance of laser trabeculoplasty : Treatment of open-angle glaucoma.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Laser trabeculoplasty is a common glaucoma therapy that is safe and effective for reducing intraocular pressure. It was developed as a treatment for open-angle glaucoma in the 1970s, and larger studies proved its effectiveness in the years that followed. In recent years, through the implementation of newer processes such as selective laser trabeculoplasty, laser trabeculoplasty has experienced further developments. Because it causes less damage to the trabecular meshwork, it should have fewer adverse effects, making it a repeatable treatment. Studies on the indications, contraindications, and effectiveness of this meth...

[Laser trabeculoplasty: therapeutic options and adverse effects.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Laser trabeculoplasty is a simple method for treating glaucoma and ocular hypertension and has few adverse effects. There are different laser systems for reducing the intraocular pressure of patients with glaucoma and ocular hypertension. Complications include transient intraocular pressure elevation, iritis, and anterior synechiae. PMID: 19844722 [PubMed - as supplied by publisher] (Source: Der Ophthalmologe)

[Available laser systems and mechanism of action in laser trabeculoplasty.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This article presents the currently most popular laser systems. These various laser procedures are based on the physical structure of the different lasers and on variable generation of laser light. They vary in their effect on the trabecular meshwork on a histopathological level, as well as in the active principles of intraocular pressure reduction. The mechanical, biological, and repopulation theories are currently used to explain the intraocular pressure-lowering effect of the different laser systems; these are discussed in detail.

[Volume calculations for current intravitreal injections of Lucentis(R).]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: The original aliquots of Lucentis(R) contain a full volume of 0.23 ml and are not suitable to be used to treat two patients. The volume can only be divided among several patients if several original aliquots are pooled and refilled. This however, presupposes a renewed filling of aliquots which represents a new potential source of contamination. Also legal aspects and the question of stability of the active ingredient have not been taken into consideration. PMID: 19838710 [PubMed - as supplied by publisher] (Source: Der Ophthalmologe)

[Acute retinal necrosis from the virologist's perspective.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Acute retinal necrosis occurs in approximately one per million persons per year and is caused in approximately 70% of the cases by the varicella zoster virus or in about 30% of the cases by herpes simplex virus. The early diagnosis is primarily based on virus-specific polymerase chain reaction in fluid from the anterior chamber or vitreous humor and can be supported by the determination of specific antibody titers from fluid and serum. Virus detection provides the basis for early causative therapy which limits disease progression and risk of complications. Retinal infections by varicella zoster virus or herpes simplex ...

[Acute retinal necrosis : Clinical features and therapy options.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Varicella zoster virus is the most frequent cause of acute retinal necrosis (ARN) followed by herpes simplex virus. Retinal ischemia and optic nerve atrophy are the main causes of the frequently poor final visual outcome in severe cases of ARN. The clinical diagnosis of ARN should be made as early as possible. Acyclovir should be administered intravenously due to its unreliable oral bioavailability. Systemic corticosteroids should be applied to suppress tissue damage caused by the host's inflammatory response. Severe cases of ARN should be treated by early vitrectomy with diagnostic vitreous biopsy, intravitreal aciclo...

For more than 10 years eye drops made from autologous serum have become an established therapy to support corneal wound healing in ocular surface diseases, such as persistent epithelial defects and dry eye. Serum eye drops can only be dispensed by institutions which have obtained a specific license from the appropriate local authorities and this applies to only a few institutes in Germany. The main protein component of serum is albumin which is commercially available as a quality controlled medical product from the pharmaceutical industry and could thus be used as an alternative to autologous serum eye drops.

[Intracameral moxifloxacin: a safe option for endophthalmitis prophylaxis? : In vitro safety profile for intraocular application.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSION: Vigamox(R) did not show significant toxicity on primary RPEs, TMCs, LECs, CECs, or human corneal endothelium at concentrations up to 150 microg/ml. The MIC90 of moxifloxacin for pathogens commonly encountered in endophthalmitis is known to be in the range of 0.25-2.5 microg/ml. Therefore, intracameral use of Vigamox(R) at concentrations up to 150 microg/ml may be safe and effective for preventing endophthalmitis after intraocular surgery.

[Subluxation of hydrophilic acrylate intraocular lenses due to massive capsular fibrosis.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: The pattern of lens opacification should receive attention when one is choosing an IOL type. Eyes showing pseudoexfoliation syndrome as well as post-uveitis eyes might require a hydrophilic IOL for less cellular reaction, whereas a posterior subcapsular cataract might need a hydrophobic IOL to prevent a massive capsular fibrosis. In the case of increased capsular contraction, unreflected YAG laser capsulotomy may result in IOL subluxation when the lens design cannot handle capsule shrinkage, as demonstrated here.

[Scanning electron microscopic characteristics of lamellar keratotomies using the Femtec femtosecond laser and the Zyoptix XP microkeratome : A comparison of quality.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: A comparison of the two systems shows that the microkeratome creates a more homogenous cut surface. The need for preparation after automated cutting with the femtosecond laser leads to irregularities on the cut surface. The cut edges of both systems tested here differ concerning their angles on entering the tissue. With regard to the sharpness of the cuts, the qualitative aspect is nearly similar, although the cut edges of the microkeratome are serrated. Because the microkeratome-cut edge has a flatter course, the wound area might be bigger. Cut edges with the steepness produced by the femtosecond laser could ...

Treatment with two cycles of vincristine, adriamycine and dexamethasone led to a regression of the papilledema and remission of the system disease.

[Bilateral panuveitis with papillary swelling.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Lues (syphilis) is a chronic cyclic infectious disease which can continue for decades if untreated. A simultaneous HIV infection can result in false negative results in serological tests for lues. The occurrence of neurolues has frequently been described in HIV positive patients. In the differential diagnosis an early ocular manifestion of lues should be considered. A 40-year-old homosexual patient presented in our hospital with bilateral pain-free increasing loss of vision. The ophthalmological examination revealed an intermediately expressed panuveitis with streaky opacity of the vitreous body and pronounced bilatera...

[New options of high resolution optical coherence tomography in glaucoma diagnostic.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
At present time domain optical coherence tomography (TD-OCT) plays a less important role in glaucoma diagnostics and is used mainly for macula diagnostics. The Fourier domain optical coherence tomography (FD-OCT) with enhanced resolution has new options to detect glaucoma changes. This new technology is referred as frequency domain or spectral domain OCT. This paper will present current and new options of OCT in glaucoma diagnostics. Measurements of the optic nerve head and the retinal nerve fiber layer thickness using this new technology have been shown to be reproducible. Devices which use TD-OCT (e.g. Stratus-OCT) h...

[Frequency-doubling technology : A new method for determining glaucomatous visual field defects.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Glaucoma is a disease in which death of retinal ganglion cells is associated with loss of visual function. The gold standard for visual field testing has been standard automated perimetry (SAP). However, up to 30-50% of retinal ganglion cells must be lost before a scotoma is detected with SAP. Therefore, investigators have been interested in finding diagnostic techniques that would allow earlier detection of visual field loss than that detected by standard white-on-white perimetry. Frequency-doubling technology (FDT) has been suggested as a promising technique that may detect glaucomatous ganglion cell damage earlier t...

[Glaucoma diagnosis using scanning laser polarimetry.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Scanning laser polarimetry (SLP) is another technology for early glaucoma diagnosis. This technique (represented in the GDx from Carl Zeiss Meditec, Jena, Germany) is based on polarimetry and measures the retinal nerve fiber layer (RNFL) thickness. Compared with previous instruments without customized corneal compensation, the variable corneal compensation technology enables improved differentiation between glaucoma and healthy eyes. Limitations are the atypical birefringence patterns that exist in some eyes, showing false high RNFL values. The newest software uses enhanced corneal compensation (ECC) technology to avoi...

[Retinal detachment in pediatrics : Etiology and risk factors.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: The study confirms ocular trauma and myopia as important risk factors for juvenile retinal detachment. Because of the high association with malformations as an endogenous background and their conspicuous frequency in patients with bilateral retinal detachment, a genetic background for retinal detachment may be concluded.

[Volume overload from hydrogel expander after treatment for enophthalmos.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In the subject of this case report, a self-inflating hydrogel expander was implanted as a treatment for posttraumatic enophthalmos in a fully sighted eye. The intervention caused hypertropia with diplopia, restriction of eye movements, visual field defects, and colour desaturation as a result of excessive swelling of the expander. Once the expander volume was adjusted, clinical signs regressed, and the aesthetic results were excellent. Following the implantation of self-inflating orbit expanders, it is advisable to carry out immediate follow-up during the expander's swelling period, and long-term follow-up is also advi...
