[Psychosomatic aspects of dry eye syndrome]. / Psychosomatische Aspekte beim trockenen Auge.

BACKGROUND: Patients with dry eye syndrome are known to suffer from anxiety and depression. OBJECTIVES: Analysis of psychological disorders in therapy-resistant dry eye syndrome. MATERIAL AND METHODS: A retrospective analysis of the training for interactive psychiatric screening (TRIPS) questionnaire from 110 patients with therapy-resistant dry eye syndrome was carried out. The results of the questionnaire allow the diagnosis of psychological disorders and vegetative disorders. Patients were divided into groups with anxiety, depression, mixed diagnoses, vegetative disorders and no diagnosis. A sicca score was used for assessment of dryness comprising the Schirmer test, measurement of tear meniscus, break up time, lipid layer thickness, the use of fluorescein and rose bengal staining tests and the subjective visual analogue scale. The diagnosis of dry eye syndrome was compared with the psychological disorders of anxiety and depression. RESULTS: Of the patients 52.7 % had psychological disorders with anxiety in 21.8 %, depression in 15.3 %, mixed diagnoses in 14.5 %, dystonia in 25.4 % and in 22.7 % no psychological disorders were diagnosed. General anxiety was frequent and panic disorders were often associated with other kinds of anxiety. Severe depression, such as bipolar disorder was rare. Dry eye scores were highest in the mixed group (0.59), and lowest in the group with mild anxiety (0.38). No single sicca phase disorder could be correlated with any of the psychological diagnoses. CONCLUSION: Patients with therapy-resistant dry eye syndrome often suffer from anxiety and depression. The psychological stress acts on the nervous system to suppress lacrimal gland function. Further investigation of the correlation between the lacrimal tear film phase and psychological disorders is recommended. Knowledge of personality disorders may allow psychological support that would improve the treatment options for dry eye syndrome.

Significantly worse survival of patients with NIH-defined chronic graft-versus-host disease and thrombocytopenia or progressive onset type: results of a prospective study.

Chronic graft-versus-host disease (GVHD) remains a serious complication after allogeneic hematopoietic stem cell transplantation (HCT). In 2005 the National Institutes of Health (NIH) established new criteria for chronic GVHD based on retrospective data and expert recommendations. We prospectively evaluated the incidence of NIH-defined chronic GVHD and its prognostic impact in 178 consecutive patients. The cumulative incidence of chronic GVHD at 3 years was 64, 48 and 16% for chronic classic GVHD and overlap syndrome. Prior acute GVHD and myeloablative conditioning were significantly associated with increased risk of chronic GVHD. Three-year survival (overall survival (OS)) for late-acute GVHD, chronic classic and overlap chronic GVHD when assigned on day 100 were 69, 83 and 73%. OS was significantly worse for patients with platelet counts below 100 g/l at onset of chronic GVHD (35% versus 86%, P<0.0001) and progressive as compared with de novo and quiescent onset of chronic GVHD (54.5% versus 89.5% versus 84%, P = 0.022 and 0.001). Peak severity of chronic GVHD had no impact on non-relapse mortality (NRM) and OS. Recurrent acute GVHD, platelet counts below 100 g/l at diagnosis of chronic GVHD, progressive onset of chronic GVHD and advanced disease stage prior to HCT were significantly associated with increased NRM. This prospective analysis provides for the first-time data on the incidence rates of NIH-defined chronic GVHD categories and identified risk factors for the occurrence of chronic GVHD. A prognostic value of thrombocytopenia and progressive onset type of chronic GVHD for survival after HCT was observed in NIH-defined chronic GVHD.

The triple classification of dry eye for practical clinical use.

PURPOSE: "Dry Eye is a condition produced by the inadequate interrelation between lacrimal film and ocular surface epithelium, and is caused by quantitative and qualitative deficits in one or both of them. It can be produced by one or combined etiologic causes, affecting one or several of the secretions of the glands serving the ocular surface, and producing secondary manifestations of different grades of severity". Clinicians need a practical classification to face diagnosis, prognosis and treatment. Dry eyes have many etiologies and pathogenesis, different affectation of the various dacryoglands and ocular surface epithelium, and diverse grades of severity. The specialists in xero-dacryology must know these three parameters to evaluate any case of dry eye, and to establish an adequate treatment. METHODS: To facilitate this, an open session in the 8th congress of the International Society of Dacryology and Dry Eye (Madrid, April, 2005) proposed modifying the Triple Classification of dry eye approved in the XIV congress of the European Society of Ophthalmology (Madrid, June, 2003). There was consensus of all conclusions. CONCLUSIONS: The following classification has been established: First, a classification of the etio-pathogenesis, distributed in ten groups: age-related, hormonal, pharmacologic, immunopathic, hyponutritional, dysgenic, infectious/inflammatory, traumatic, neurologic and tantalic. Second, a classification of the affected glands and tissues, which under the acronym of ALMEN includes the Aqueo-serousdeficient, Lipodeficient, Mucindeficient and Epitheliopatic dry eyes, and the Non dacryological affected exocrine glands (saliva, nasal secretion, tracheo-pharyngeal secretion, etc). And thirdly, a classification of severity, in three grades: Grade 1 or mild (symptoms without slitlamp signs), grade 2 or moderate (symptoms with reversible signs), and grade 3 or severe (symptoms with permanent signs).

The clinical use of viscoelastic artificial tears and sodium chloride in dry-eye syndrome.

This study was performed to test viscoelastic artificial tears (VAT) based on both subjective and clinical parameters in patients with keratoconjunctivitis sicca (KCS). Twenty-eight patients were evaluated in a randomized double-blind study. Sodium hyaluronate was used in two different concentrations (0.4%, 0.25%) and in combination with chondroitin sulfate. Each preparation was used for one week preceded by another weekly cycle using a sodium chloride solution. Before and after each cycle, clinical examinations were performed: tear film break-up time, Schirmer's test, lipid-layer thickness and fluorescein staining. Patients kept a record of the drop-frequency, subjective response and side effects. After the study, they were asked to give a rating of the various preparations. The severity of KCS was expressed based on a sicca score and correlated with response to viscoelastic treatment. Both the subjective and the clinical parameters revealed no statistically significant differences between the various viscoelastic agents or between the viscoelastics and the sodium chloride solutions. Severe side effects did not occur. There was a positive correlation of response to viscoelastic treatment with severe KCS (+ 0.36) but not with mild KCS (-0.07). The VAT seems to be indicated in severe cases of dry-eye syndrome. Sodium chloride solutions may be a useful short-term alternative to other tear formulations.

[Excimer laser versus diamond fraise: equal short-term outcome of corneal smoothing in pterygium operations]. / Excimer-Laser versus Diamantschleifer: Gleichwertige Kurzzeitergebnisse bei Hornhautglättung nach Pterygiumoperationen.

BACKGROUND: The treatment of pterygia often results in irregular astigmatism. Corneal smoothing at the end of surgery plays a major role in the development of astigmatism. The aim of our study was to compare the efficiency of corneal smoothing performed by phototherapeutic keratectomy compared with the conventional method performed by a diamond fraise. The effect of postoperative excimer laser smoothing on refraction, visual acuity and irregular astigmatism was investigated. PATIENTS AND METHODS: 32 eyes underwent pterygium excision using a standardized surgical procedure. In addition 9 eyes underwent postoperative phototherapeutic keratectomy of the wound region with an excimer laser, 23 eyes were treated with a diamond fraise for corneal smoothing. The postoperative examination was performed 7, 14 and 30 days after surgery. Corneal topography was performed by a computer-assisted videokeratoscope (TMS-1). The results were evaluated by the Fourier transform analysis. RESULTS: Both methods showed similar results concerning refraction and visual acuity postoperatively. Preoperatively all patients had an irregular flattening of the corneal topography in the area of the pterygium. Postoperatively a small irregular flattening was left in eyes treated with a diamond fraise. In the excimer laser treated group a steepening in the corneal topography could be observed. CONCLUSIONS: The phototherapeutic keratectomy with excimer laser in the treatment of pterygia suggests to be a gentle alternative creating a smooth wound surface. Despite of this advantage the treatment with the excimer laser effects a remarkable increase in administration and expense.

Inflammation after phacoemulsification in diabetic retinopathy. Foldable acrylic versus heparin-surface-modified poly(methyl methacrylate) intraocular lenses.

PURPOSE: To evaluate inflammation after cataract surgery in patients with nonproliferative diabetic retinopathy (NPDR) and compare results with 2 intraocular lenses (IOLs): a foldable hydrophobic acrylic and a heparin-surface-modified (HSM) poly(methyl methacrylate) (PMMA). SETTING: Department of Ophthalmology, University of Vienna, Vienna, Austria. METHODS: Patients with NPDR were randomized for implantation of an HSM PMMA IOL (811C, Pharmacia) through a 6.0 mm sclerocorneal incision (30 patients) or a foldable hydrophobic acrylic IOL (AcrySof, Alcon) through a 4.0 mm sclerocorneal incision (32 patients). Both IOLs had 6.0 mm optics. All patients were treated according to a standardized protocol. The degree of flare in the anterior chamber was measured with the Kowa 1000 laser flare-cell meter 1 day preoperatively and 1 day, 1 week, and 1 and 3 months postoperatively. RESULTS: In both IOL groups, flare was highest on the first postoperative day and decreased to preoperative levels by 3 months after surgery. There was no statistically significant difference in relative flare values between the 2 groups. CONCLUSION: There was no difference in postoperative inflammation in eyes with a foldable hydrophobic acrylic IOL implanted through a small incision and those with a rigid HSM PMMA IOL. Postoperative inflammation results indicate that the lenses are equally suitable for the use in patients with diabetic retinopathy.

Treatment of keratoconjunctivitis sicca with topical androgen.

OBJECTIVE: Androgens have been reported to influence lipid production of sebaceous glands and even many ocular tissues. The effect of topical androgen therapy on a 54-year-old patient with keratoconjunctivitis sicca (KCS) and decreased lipid phase of the tear film is reported. METHODS: For assessment of the lipid phase of the tear film, break up time (BUT) and lipid layer thickness (LLT) were monitored during 6 months before treatment as well as 3 months while using a daily topical androgen therapy. RESULTS: During the topical androgen therapy the pathological lipid phase of the tear film was completely restored indicated by the normalisation of the values of BUT and LLT. CONCLUSION: These findings are consistent with animal experiments indicating that topical administered androgen can restore the decreased lipid phase of the tear film. This may open up new therapeutic strategies for KCS.

Psychiatric disorders in patients with blepharospasm - a reactive pattern?

OBJECTIVE: The purpose of this study was to assess the life-time prevalence of all major psychiatric disorders in patients suffering from blepharospasm. METHOD: A total of 31 consecutive patients with blepharospasm attending the Department of Neurology were interviewed at the Department of Psychiatry at the University of Vienna. Patients had been submitted to standard neurological diagnostic procedures, psychiatric diagnoses were made with the help of the SCID, functional impairment was assessed by the General Assessment of Functioning Scale (GAF). RESULTS: A current or life-time psychiatric diagnosis was made for 22 patients (71%). The most frequent disorders were depressive disorders, mainly major depression (five patients, 16.1%), secondary dysthymia (six patients, 19.3%), and recurrent major depression (five patients, 16.1%). A diagnosis of simple phobia was made for seven patients (22.5%), for obsessive-compulsive disorder in three patients (9.6%). The mean GAF score of our sample was 63.1%. CONCLUSION: In contrast to previously published results, we did not find a high rate of a single specific disorder or patterns in our study sample, though by the inclusion of life-time diagnostic criteria, the majority of patients fulfilled criteria for at least one diagnosis. This might indicate the considerable negative impact of blepharospasm on the patients' lives.

Is there a correlation between the severity of diabetic retinopathy and keratoconjunctivitis sicca?

PURPOSE: Patients with diabetic retinopathy (DRP) seldom report symptoms of ocular surface irritation, but evaluations of dryness are pathologic. This study was designed to evaluate the correlation between the severity of DRP and dry eyes. METHODS: We included 144 eyes of 72 patients. Severity of retinopathy was graded according to the Early Treatment Diabetic Retinopathy Study. The examinations for dry eyes included Schirmer's test, break-up time, lipid layer thickness, fluorescein and rose bengal staining of the cornea, impression cytology, and a questionnaire. A sicca severity score was calculated using a point system of the results of these tests. Patients were divided into three groups: postpanretinal laser coagulation (PPL), postcentral laser coagulation (PCL), and those with no laser treatment (0-L). For statistics, we used the correlation coefficient to determine relationships and the unpaired Student t test for statistical difference. RESULTS: The correlation (c) of keratoconjunctivitis sicca (KCS) and DRP after laser treatment was c = 0.24 and after central laser treatment was c = 0.22; the correlation without laser treatment was 0.54. The best correlation is 1 or -1, the worst was 0. The score of those patients with mild to moderate retinopathy was compared to that of patients with severe to proliferative disease. There was a significant statistical difference in the sicca severity score between both groups, (p < 0.006. Student t test). CONCLUSION: KCS represents another manifestation of diabetes mellitus and its severity--measured by a many-membered score--correlates with the severity of the DRP.

Tolosa Hunt Syndrome--intractable pain treatment with acupuncture?

PURPOSE: The Tolosa Hunt Syndrome (THS) is a painful granular inflammation of the cerebral vessels followed by pain and disorders of the extrabulbar muscles. The therapy consists of corticosteroids and analgetics. There was a 70 year old woman who suffered from painful paresis of the abducent and oculomotor nerves following an infection with Borrelia Burgdorferi--but without ocular symptoms. The treatment with corticosteroids reduced the palsy but she complained of excessively painful attacks in the region of the first branch of the trigeminal nerve. Opiold analgetic therapy did not bring about any relief. Acupuncture is an irritative method with a physical effect on the nervous system: its pain-reducing effect is caused by the activation of transmitters like endorphins in thalamus and brain stem. Knowing this effect, the THS patient, after informed consent, was treated with acupuncture. To measure the extent of pain, a visual analog scale (0: no pain - 10: maximum pain) was used. Acupuncture was performed according to the empirical rules of the Traditional Chinese Medicine (TCM), during a period of 10 weeks and 12 weeks. There was a significant pain relief after acupuncture from VAS 10 to VAS 5. The effect vanished during the next four months. After a second series of 12 sessions pain reduction was reported from VAS 10 to 4. One year after the last Tolosa Hunt Syndrome - intractable pain pain strength ranged between VAS 4 - 6. Therefore acupuncture seems to be a good additional method for reduction of intractable pain.

[Effect of acupuncture in keratoconjunctivitis sicca]. / Akupunktureffekt bei Keratoconjunctivitis sicca.

BACKGROUND: Conjunctivitis sicca is a chronic disease of the ocular surface. The substitution of tear deficiency with artificial tears is not satisfying in many patients. In a series of patients successfully treated with acupuncture we observed very different effects on each patient. In this study we evaluate the correlation between the effect of acupuncture and the etiology of the dry eyes treated. PATIENTS AND METHODS: 102 patients (87 women, 15 men) with dry-eye syndrome have been needed 10 sessions, once per week, for 30 minutes. We recorded causal factors according to the traditional chinese medicine (TCM): external and internal factors. External factors were: toxic, allergic, drug-induced, ocular surface inflammation and infection, contact lens and generally external irritations. Internal factors were disorders of hormones, immune system, psychic, and vitamin-A deficiency. Ophthalmologic observation included the slit-lamp examination, Schirmers test II, break-up time of tear film (BUT) and a drop-frequency protocol--before and 1 week after acupuncture treatment. RESULTS: There was a statistically significant difference (p < 0.001) in Schirmers test, BUT and drop frequency between before and after acupuncture. There was no significant difference between internal and external factors, but the effect on external induced sicca was better. The best effect of acupuncture was found in external factors after inflammation and in patients with imbalance of the autonomic nervous system, the least effects in Sjögren Syndrome. The effect was better in younger then in patients over 50 years. CONCLUSION: The study demonstrate, according DeLa Fuye that the best effect of acupuncture is seen on functionally disorders.

Penetration and decay of meropenem into the human aqueous humor and vitreous.

The aim of this study was to determine the penetration of intravenously administered meropenem into the human aqueous humor and vitreous. Thirty patients about to undergo cataract surgery and fourteen patients about to undergo vitrectomy received a 2 g dose of meropenem before surgery. Specimens of aqueous humor or vitreous and blood were obtained intraoperatively and analyzed by high performance liquid chromatography (HPLC). The study was designed as a non-randomized prospective trial. Thirty min to 12 hr after administration, mean aqueous humor levels of 13.4 and 1.1 mg/l and vitreous levels between 8.94 and 1.08 mg/l were found, respectively. The peak concentrations are distinctly above the in vitro measured minimum inhibitory concentration of meropenem for 90% (MIC90) of almost all relevant gram-positive and gram-negative organisms, including Pseudomonas aeruginosa and Enterobacteriaceae. With regard to its broad spectrum, high antibacterial activity, and good penetration into ocular fluids, meropenem seems to be an alternative to currently used systemic drugs. Its usefulness in perioperative prophylaxis, as initial therapy after perforating or penetrating injuries, or in the therapy of bacterial endophthalmitis has yet to be proved.

[Etiology of non-penetrating corneal injuries]. / Atiologie nicht penetrierender Hornhautverletzungen.

BACKGROUND: Non-penetrating injuries of the cornea are frequent. Complications like corneal infiltrations, or corneal ulcera, may follow. MATERIAL AND METHODS: This prospective study included 144 patients with non-penetrating corneal injuries. Records contained epidemiological data, field of activity, profession, cause of the injury, and stress during the trauma. RESULTS: 97% of the patients were men, 78% of the injuries occurred during working hours, 41% of the patients were from metal working professions, 73% of the accidents happened with grinding machines and drilling machines. Only 6.9% of patients weared adequate glasses. The cause of trauma was deflection and working without glasses. In 32% of patients stress played a role in the cause of injuries. CONCLUSIONS: Most of the corneal, non penetrating injuries happened during the working hours by deflection, and by neglecting safety glasses. With the use of safety glasses the number of corneal non-penetrating injuries could definitely be reduced.

[Blepharospasm and acupuncture--initial results of a treatment trial]. / Blepharospasmus und Akupunktur--erste Ergebnisse eines Behandlungsversuches.

Blepharospasm is a dystonia of the orbicularis muscle. The background is still unknown, but it appears together with organic and psychic diseases. The therapy with botulinum toxine is symptomatically but efficient. Because of the relaxing effect on the psychological and autonomous nervous disorders we performed a pilot study with acupuncture. There was a neurological observation first, then a ophthalmologic examination of the ocular surface. Blepharospasm was measured by the Visual Analogue Scale (VAS), the social disorders by the Elston-Score. We performed acupuncture treatment 10 times once weekly. The used points were local points with higher sensitivity, and points with empiric relaxation effect. 5 patients were included. The mean of Elston score was 3 before acupuncture and 4 after acupuncture. The VAS increased from 33.3 to 69/100 points. But there were fluctuations of dystonias. In conclusion acupuncture maybe a good method for this difficult disease additionally.

Intraoperative and postoperative complications of high-frequency capsulotomy and continuous curvilinear capsulorhexis.

PURPOSE: To compare the intraoperative complications and postoperative blood-aqueous barrier (BAB) disturbance after high-frequency capsulotomy and continuous curvilinear capsulorhexis (CCC). SETTING: Vienna General Hospital, Vienna, Austria. METHODS: This prospective, randomized clinical study evaluated 53 eyes with senile cataract. Patients were divided into two groups: high-frequency capsulotomy (n = 27) or CCC (n = 26). The surgical procedure and postoperative therapy were standardized for both groups. The intraoperative course was documented, and postoperative complications were examined by biomicroscopy 3 months postoperatively. Without the pupil dilated, BAB disturbance was evaluated with a laser flare-cell meter at 1, 3, 7, and 14 days postoperatively. The findings were analyzed statistically. RESULTS: Intraoperatively, the high-frequency capsulotomy group had a significantly higher rate of radial tears in the anterior lens capsule. Postoperatively, this resulted in a higher incidence of postoperative false positioning of the intraocular lens. At no time were the flare-cell meter results between groups statistically significant. CONCLUSION: High-frequency capsulotomy resulted in no more trauma than CCC. It can be a good alternative to conventional techniques, particularly in eyes with no red reflex. However, the technique is associated with less mechanical stability.
