[Viral Conjunctivitis: Findings, Therapy, and Prophylaxis]. / Virale Bindehautentzündungen: Befunde, Therapie und Prophylaxe.

Viral conjunctivitis is one of the most common acute eye diseases. The fall and winter months are known to be the main season for viral infections which is also reflected in the ophthalmological outpatient clinics. Viral conjunctivitis is often accompanied by symptoms of the upper and lower respiratory tract, fever, chills, arthralgia or skin lesions. The spectrum of pathogens comprises DNA viruses such as Adeno-, Herpes simplex and Molluscum contagiosum as well as RNA viruses. Symptoms caused by pandemic pathogens such as SARS-CoV-2 and mpox viruses can also cause ocular manifestation. Viral conjunctivitis is often self-limiting leaving no residual symptoms, however an ophthalmologist should be consulted if there are inflammatory symptoms of the anterior eye accompanied by visual disturbance. It is particularly important to recognize the affection of corneal or even intraocular structures early to initiate an adequate and effective therapy. Affection of the cornea, vitreus or retina can result in temporary or permanent impairment of the field of vision and visual acuity. The diagnosis is usually made without further tests on the basis of the typical clinical presentation. Rapid tests or PCR diagnostics are also available for confirmation. In most patients the treatment is symptomatically with artificial tears and antibiotic eye drops in cases accompanied by secondary bacterial infections, not prophylactically. If the cornea or other ocular structures are affected by certain viruses, local as well as systemic virostatic therapy is initiated. The most important prophylactic measure is meticulous and consistent hygiene.

Health Literacy in Patients Wearing Prosthetic Eyes: A Prospective Cross-Sectional Study.

PURPOSE: To investigate general and electronic health literacy (HL) levels in prosthetic eye wearing patients, to define factors associated with reduced HL, and to identify a potential healthcare gap. METHODS: In this prospective cross-sectional study 148 prosthetic eye wearers were screened using the 16-item European Health Literacy Survey Questionnaire (HLS-EU-Q16) and the 8-item electronic Health Literacy Scale (eHEALS). HLS-EU-16 and eHEALS scores were correlated to health levels, vision functioning, and sociodemographic factors. RESULTS: A total of 85 patients (57%) had adequate, 38 (26%) problematic, and 9 (6%) inadequate general HL, while 16 (11%) had no valid HLS-EU-Q16 score. General HL was positively correlated with physical health (p = 0.009) and negatively with a migration background (p = 0.023). There was a positive correlation between electronic HL and educational level (p < 0.001), social status (p = 0.048), and mental health (p = 0.013). Higher age was associated with lower electronic HL (p < 0.001). CONCLUSIONS: More than 30% of the prosthetic eye wearers had problematic or even inadequate general HL, suggesting a significant health care gap. To identify patients with reduced HL, a standardized screening tool should be implemented as part of routine clinical care. Within integrated care, patients with insufficient HL should be offered barrier-free advisory services and information brochures in various languages.

Short-term changes in Bruch's membrane opening-based morphometrics during the first week after trabeculectomy.

PURPOSE: To evaluate the dynamics of Bruch's membrane opening-based morphometrics of the optic nerve head (ONH) using spectral-domain optical coherence tomography (SD-OCT) during the first week after glaucoma surgery by trabeculectomy with mitomycin C. METHODS: Prospective, longitudinal analysis of 25 eyes of 25 patients treated by trabeculectomy. Twenty-four eyes had evaluable postoperative SD-OCT examinations. Bruch's membrane opening minimum rim width (BMO-MRW) and peripapillary retinal nerve fiber layer (RNFL) thickness were analyzed at baseline before surgery, 1 day, 2 to 3 days, and 1 week after surgery. Changes compared to baseline were correlated to intraocular pressure (IOP). RESULTS: One day after surgery, the mean BMO-MRW changed by + 26.17 µm, p = 0.001 (mean IOP reduction by 17.01 mmHg). This increase persisted on day 2-3 with a mean increase of BMO-MRW of + 25.33 µm, p = 0.001 (mean IOP reduction by 20.46 mmHg) and by week 1 with a mean BMO-MRW increase of + 33.17 µm, p < 0.001 (mean IOP reduction by 22.55 mmHg). The increase in BMO-MRW correlated significantly with the reduction of IOP on day 1 (Spearman's rho ρ = 0.656, p = 0.003) and d2-3 (Spearman's rho ρ = 0.479, p = 0.038). There was no statistically significant correlation found between the IOP and the increase in BMO-MRW in week 1. RNFL thickness showed no significant changes at day 1 as well as days 2-3 (p ≥ 0.078, respectively). It showed a small but significant increase in week 1 by 3.94 µm, p = 0.015. CONCLUSIONS: Structural reversal of disc cupping in BMO-MRW occurs as early as 1 day after trabeculectomy and correlates to the extent of the IOP reduction. During the whole first week after surgery, a strong increase in BMO-MRW can be noted. The changes in BMO-based parameters need to be considered when evaluating patients' longitudinal follow-up.

Dynamics of structural reversal in Bruch's membrane opening-based morphometrics after glaucoma drainage device surgery.

PURPOSE: Structural reversal of disc cupping is a known phenomenon after trabeculectomy. The aim of this retrospective, longitudinal, cross-sectional analysis was to evaluate the postoperative dynamics of Bruch's membrane opening-based morphometrics of the optic nerve head following glaucoma drainage device surgery. METHODS: Forty-three eyes, treated by glaucoma drainage device surgery, were included in the study. Individual changes in the spectral domain optic coherence tomography (SD-OCT) parameters Bruch's membrane opening minimum rim width (BMO-MRW), Bruch's membrane opening minimum rim area (BMO-MRA) and peripapillary retinal nerve fiber layer (RNFL) thickness as well as mean defect in 30-2 perimetry were analyzed. Changes were correlated to postoperative intraocular pressure levels over time. Available follow-up visits were aggregated and grouped into a short-term follow-up (20 to 180 days after surgery), a midterm follow-up (181 to 360 days after surgery) and a long-term follow-up (more than 360 days after surgery). RESULTS: In short-term follow-up, BMO-MRW and BMO-MRA increased significantly (p <= 0.034). This increase correlated negatively with the intraocular pressure at the time of the follow-up (Pearson's rho = - 0.49; p = 0.039). From 6 months after surgery on, there was no statistically significant change in BMO-MRW and BMO-MRA (p >= 0.207). RNFL thickness and mean defect of 30-2 perimetry showed no significant changes after GDD implantation (p >= 0.189). CONCLUSIONS: Lowering of intraocular pressure by glaucoma drainage device surgery leads to an increase of Bruch's membrane opening based parameters in the first 6 months after surgery. These changes have to be taken into account when evaluating patients' longitudinal follow-up after glaucoma drainage device implantation.

[Diversity in daily clinical practice of ophthalmology]. / Diversität im klinischen Alltag der Augenheilkunde.

BACKGROUND: People with an immigration background often encounter a multitude of barriers in the healthcare system, which may have negative impacts on medical care. Ophthalmology is also coming under ever-increasing pressure from this diversity issue in the clinical routine. OBJECTIVE: This review outlines the different aspects of diversity and their significance for the patient care in ophthalmology. METHODS: The study is based on a PubMed literature review and own experiences. RESULTS: Optimal implementation of intercultural expertise requires awareness of one's own values and norms in order to be able to relate these to the norms and values of migrants in an optimal manner. The goal of diversity in medicine includes a holistic approach to view each patient as a whole. It is crucial to adopt an empathetic attitude towards the individuality and cultural attitudes of patients. An enhanced well-being of the patients goes hand in hand with the willingness to incorporate cultural peculiarities as well as religious norms and values into the treatment within the framework of a good relationship between doctors, nursing staff and patients. This ultimately increases the positive basic attitude and supports active healing, also in the discipline of ophthalmology. CONCLUSION: Awareness and acceptance of the significance of diversity facilitate the clinical care of patients in ophthalmology.

Impact of ab-interno trabeculectomy on Bruch's membrane opening-based morphometry of the optic nerve head for glaucoma progression analysis.

PURPOSE: To analyze the longitudinal change in Bruch's membrane opening minimal rim width (BMO-MRW) and circumpapillary retinal nerve fiber layer (RNFL) thickness using spectral domain optical coherence tomography (SD-OCT) after glaucoma surgery via ab-interno trabeculectomy in adult glaucoma patients. METHODS: Retrospective audit of 65 eyes of 65 participants undergoing ab-interno trabeculectomy using electroablation of the trabecular meshwork. In 53 eyes, surgery was combined with phacoemulsification and posterior chamber lens implantation. Pre- and postoperative SD-OCT examinations of the optic nerve head (ONH), intraocular pressure (IOP), and visual field data were analyzed. Longitudinal change in morphometric SD-OCT parameters of the ONH was compared and correlated to change in IOP and visual field function. RESULTS: BMO-MRW increased significantly between baseline (BL) and follow-up (FU) within the first 6 months after surgery (BL = 167.85 ± 90 µm; FU = 175.59 ± 89 µm; p = 0.034). This increase correlated with postoperative lowering of IOP (rho = - 0.41; p = 0.016). Nine months after surgery (range, 7-12 months), there was no significant change in BMO-MRW (BL = 196.79 ± 79; FU = 196.47 ± 85 µm; p = 0.95), while in later follow-up, a decrease of BMO-MRW was found (BL = 175.18 ± 78; FU = 168.65 ± 72; p = 0.05). RNFL thickness was unchanged in early (p > 0.16) and significantly decreased in later follow-up (p = 0.009). Mean deviation (MD) of visual field function did not show a significant change before and after surgery. CONCLUSION: Electroablative ab-interno trabeculectomy leads to a significant transient mild increase in BMO-MRW. This increase was shown to correlate with IOP lowering. Significant loss of BMO-MRW in later follow-up may reflect insufficient IOP reduction by surgery. The parameters RNFL thickness and MD seem less impacted directly by surgery.

Structural Reversal of Disc Cupping After Trabeculectomy Alters Bruch Membrane Opening-Based Parameters to Assess Neuroretinal Rim.

OBJECTIVE: To assess the impact of trabeculectomy for glaucoma on morphometric neuroretinal parameters of the optic nerve head (ONH) using spectral-domain optical coherence tomography (SD-OCT). DESIGN: Retrospective, interventional case series. METHODS: Participants: Eighty-eight eyes of 88 patients who underwent trabeculectomy with mitomycin C in 2016. INTERVENTION: All patients underwent trabeculectomy in 1 eye (study eye) and had evaluable SD-OCT examinations of the ONH to measure neuroretinal tissue before and at least at 1 of the 3-, 6-, and 12-month follow-up time points after surgery. MAIN OUTCOME MEASURES: Longitudinal change in Bruch membrane opening minimum rim width (BMO-MRW), Bruch membrane opening minimum rim area (BMO-MRA), peripapillary retinal nerve fiber layer (RNFL) thickness, intraocular pressure (IOP), and mean deviation in perimetry. RESULTS: In study eyes, BMO-MRW significantly increased postsurgically comparing baseline and follow-up examinations at 3 months (P = .012), at 6 months (P = .007), and at 1 year (P = .010) after trabeculectomy. The increase in BMO-MRW 6 months after surgery correlated with IOP reduction (r = 0.48; P = .001). BMO-MRA showed an equal increase (P ≤ .034). RNFL thickness remained stable between baseline and follow-up at 3, 6, and 12 months and showed a moderate loss after 18 months (P = .021) of follow-up. CONCLUSIONS: Structural reversal of disc cupping after trabeculectomy markedly influences Bruch membrane opening-based parameters for up to more than 1 year. Improvement in morphometry seems to correlate with the reduction of IOP while visual field function appears not to be influenced. In longitudinal follow-up of glaucoma patients by SD-OCT, evaluation of BMO-based parameters necessitates to reflect bias caused by surgery.
