Recurrent corneal erosions related to an ocular injury 15 years before presentation.

Purpose: To report the case of a patient who presented with recurrent corneal erosions caused by an undetected plastic foreign body in the upper eyelid, which had remained asymptomatic for nearly 15 years following an ocular injury. Observations: A 39-year-old patient presented with recurrent corneal erosions and frontal headaches of unknown aetiology over the preceding eight months. The patient had previously been seen by twelve different ophthalmologists and had been treated over a 6-month period with a bandage contact lens, and therapeutic corneal scraping had been performed twice. However, the corneal erosion had repeatedly reappeared after removal of the bandage contact lens. On clinical examination prior to a planned phototherapeutic keratectomy, we extracted a 1.5 cm plastic foreign body, localised in the subtarsal area of the upper conjunctival fornix. Upon specific questioning, the patient denied any recent trauma, but reported a work-related accident with an accompanying eye injury 15 years before presentation. Conclusions and importance: Posttraumatic foreign bodies in the eye may remain asymptomatic for prolonged periods before giving rise to clinical signs such as recurrent corneal erosions. Hence, a thorough clinical examination with meticulous eyelid eversion should always be performed in such patients.

Effectiveness of immediate vitrectomy and intravitreal antibiotics for post-injection endophthalmitis.

PURPOSE: To show that an immediate vitrectomy with an intravitreal injection of antibiotics can be an effective approach for the treatment of acute endophthalmitis following intravitreal injections. METHODS: We reviewed all cases of clinical endophthalmitis caused by an intravitreal injection that were treated in our department between March 2012 and November 2019. Only patients that underwent a vitrectomy within 6 h after presentation to the clinic and with a documented visual acuity shortly before the causative event were included. Baseline best-corrected visual acuity (BCVA) before the causative event was compared to BCVA measured within a follow-up period of 8 months (up to 14 months). RESULTS: In total, 30 eyes of 30 patients were included. The BCVA before the intraocular infection was a mean value of 0.55 logMAR, and the BCVA on the day of the endophthalmitis decreased significantly to 1.66 logMAR. Within 2 months following the pars plana vitrectomy (PPV), the mean BCVA improved to 0.83 logMAR. Eight months following PPV (mean value, 8.20 months; SD, 3.59 months), the mean BCVA was 0.63 logMAR. In the last follow-up interval most of the eyes recovered, and the BCVA did not differ significantly from baseline. Two eyes underwent further pars plana surgery during the follow-up period. No enucleation was required. CONCLUSION: In this study, we have shown that an immediate vitrectomy with subsequent intravitreal injection of antibiotics is an effective option for treating post-injection endophthalmitis and frequently results in recovery of vision; thus, it should be performed as early as possible, where available.

[Microbiological and infectious disease aspects of postoperative endophthalmitis]. / Mikrobiologische und infektiologische Aspekte der postoperativen Endophthalmitis.

Infectious postoperative or postinjection endophthalmitis is a medical emergency. Gram-positive bacteria, such as staphylococci, streptococci and enterococci are the predominant causative agents, whereas Gram-negative pathogens (e.g. Klebsiella pneumoniae, Pseudomonas aeruginosa) and fungi account for a minority of cases. Using modern diagnostic tools, which include polymerase chain reaction-based assays in addition to Gram staining and agar culturing, a causal agent can be detected in the majority of cases, which enables a targeted treatment and estimation of the prognosis. Endophthalmitis is treated with intravitreal and often also intravenous administration of antibiotics, with the combination of vancomycin and ceftazidime being most commonly used. This article presents and summarizes recent developments in the microbiological etiology and diagnostics of endophthalmitis as well as treatment options and perioperative antibiotic prophylaxis in the light of emerging resistance patterns.

Feasibility of a Virtual Reality-Based Psychoeducational Tool (VRight) for Depressive Patients.

E-health is opening new prospects in the management of mental disorders. Virtual reality (VR)-based interventions, which provide a safe nonjudging environment, may improve symptoms awareness in patients with depressive disorders. This study aimed to explore the feasibility of a novel VR software, the VRight, in depressive patients. Adult outpatients with depressive disorders presenting to our mental health clinic during December 2018 were invited to participate in the study. Participants completed a satisfaction survey at the end of the session, including questions about user-friendliness and about usefulness of the software. The Patient Health Questionnaire-9 (PHQ-9) was administered to participants before and after the VR-based intervention to assess depressive symptoms severity. We explored the correlation between the score difference and the variables: age, gender, and initial score. Twenty-eight patients (71.4 percent women, mean age: 51.18 ± 16.13 years) were recruited. Thirteen subjects had major depressive disorder (46.4 percent). Most of the patients (n = 26) were satisfied with the VR experience, which they found to be helpful. PHQ-9 score difference and the initial score correlated positively at a significant level. There was no significant correlation between score difference and age or gender. VRight was well accepted among depressive patients, showing high levels of satisfaction. The VRight could contribute to increase depressive symptoms awareness, which is of clinical relevance given the association of greater insight with positive outcomes in depression. Further studies are needed to confirm the effectiveness of VRight as a psychoeducational tool in clinical practice.

Intra- and postoperative risks and complications of small-gauge (23-G) versus conventional (20-G) vitrectomy for macular surgery.

PURPOSE: To compare the complication spectrum and rate of 23-G and 20-G vitrectomy for macular surgery. METHODS: This was a retrospective comparative analysis of 20-G and 23-G vitrectomy (introduced in 2007) for macular surgery due to macular pucker or macular hole performed between 2006 and 2010 in 61 and 59 eyes, respectively, by 2 experienced surgeons and 2 trainees. We assessed the adjusted hazard ratio for vitrectomy 23-G vs 20-G with a Cox proportional hazard model. We counted retinal detachment, vitreous hemorrhage, endophthalmitis (as early postoperative complications), or cataract progression (as late postoperative complication) as endpoint. We adjusted for indication, surgeon, retinopexy method, and the endotamponade. RESULTS: Follow-up averaged 712 days. Median time to first event was 385 days in the 23-G group and 342 days in the 20-G group. Cox proportional hazard analysis showed no significant difference between vitrectomy 23-G vs 20-G with regard to postoperative complications (hazard ratio 0.79, 95% confidence interval 0.41-1.52). The other covariates did not exert a statistically significant effect on the risk of adverse events. Looking at individual complications, retinal detachment was exclusively found after 20-G. CONCLUSIONS: In this homogenous large cohort, we did not find a statistically significant difference in rates of complications between 23-G and 20-G vitrectomy techniques for macular surgery. Trainees performed equally well as experienced surgeons.
