Ocular manifestation of hand, foot, and mouth disease : A case series.

Virus-related illnesses are a common phenomenon, especially in the colder months of the year. They usually manifest with cough, cold, and other flu-associated symptoms. They affect people of all ages and genders. In recent years, also virus-associated ocular symptoms have been documented repeatedly. One of the viruses known to cause these is the Coxsackievirus A, which causes hand, foot, and mouth disease. Three cases of these virus-associated macular changes are described below. In all three cases, the symptoms occurred unilaterally and with little time delay to the virus-typical general changes. Complete functional remission occurred in all cases, whereby permanent changes in the pigment epithelium were observed.

Effect of intravitreal injections due to neovascular age-related macular degeneration on retinal nerve fiber layer thickness and minimum rim width: a cross sectional study.

PURPOSE: The present study tested the hypothesis that repeated anti-VEGF injections are associated with reduced retinal nerve fiber layer (RNFL) and minimum rim width (MRW) of the optic nerve head. PATIENTS AND METHODS: Sixty-six patients with a history of intravitreal injections due to neovascular age-related macular degeneration were included. RNFL and MRW were measured using optical coherence tomography (Spectralis OCT, Heidelberg Engineering, Heidelberg, Germany). RESULTS: Mean global RNFL was 90.62 µm and both RNFL as well as MRW significantly decreased with advanced age (p = 0.005 and p = 0.019, respectively). Correlating for the number of injections, no significant impact on RNFL was found globally (p = 0.642) or in any of the sectors. In contrast, however, global MRW was significantly reduced with increasing numbers of intravitreal injections (p = 0.012). The same holds true when adjusted for the confounding factor age (RNFL p = 0.566 and MRW p = 0.023). CONCLUSION: Our study shows that repeated intravitreal injections due to choroidal neovascularization seem to have a deleterious effect on MRW but not on RNFL. This suggests that MRW is a more sensitive marker than RNFL for evaluating the effect of frequent intravitreal injections on the optic nerve head since it seems to be the first structure affected.

Brolucizumab for pre-treated patients with choroidal neovascularization and signs of tachyphylaxis to aflibercept and bevacizumab.

PURPOSE: Treatment of choroidal neovascularization due to age-related macular degeneration is a challenging topic since an increasing number of patients show reduced morphological response to conventional treatment with intravitreal injections. The present study tested the hypothesis that the newly introduced anti-VEGF antibody brolucizumab does not only show promising results in pre-treated patients but is also a viable option in cases of tachyphylaxis to aflibercept or bevacizumab. METHODS: Thirty-six eyes of 34 patients with a history of at least 10 anti-VEGF injections as well as persistent retinal fluid following the past 5 monthly injections with aflibercept and bevacizumab prior to first treatment with brolucizumab were included in the study. Morphological and functional treatment response was compared before and after switching to brolucizumab. RESULTS: Mean best-corrected visual acuity did not significantly change after treatment with brolucizumab. In contrast, central retinal thickness significantly decreased 4 weeks after treatment with brolucizumab from 340.36 to 282.22 µm (p < 0.001) as well as pigment epithelial detachment from 346.73 to 280.47 µm (p < 0.001). In 24 eyes (66.67%), complete resolution of intra-and subretinal fluid was observed after a single dose of brolucizumab. No serious adverse events, such as intraocular inflammation and retinal vasculitis, were reported after a single injection of brolucizumab. CONCLUSION: Brolucizumab is not only effective in treatment-naïve patients as shown in the pivotal HAWK and Harrier trials, but also in pre-treated patients as seen in the present study. Our data also suggest that brolucizumab is potent in patients with signs of tachyphylaxis to other anti-VEGF agents and thus a viable treatment option.

Level of knowledge about glaucoma in Vienna.

BACKGROUND: Glaucoma is a chronic and serious disease calling for consistent lifelong therapy. The patient's compliance requires that he/she be well informed about the disease. The purpose of the present study was to determine the level of knowledge about glaucoma, and compare young patients with older ones as well as glaucoma patients with nonglaucoma ones. METHODS: A total of 1110 questionnaires were distributed to patients and their relatives at the outpatient eye clinic of Hietzing Hospital (Vienna), of which 1041 were returned. The questionnaire comprised 18 questions. Patients were divided into two groups: group 1 consisted of those aged 18-60 years, while group 2 consisted of those older than 61 years. RESULTS: In total, 941 questionnaires were evaluated; 72.8% of the respondents were older than 60 years, and one-half of the respondents had glaucoma (51%). The majority of patients had "moderate knowledge" of the disease (41.87%), followed by "poor knowledge" (32.52%). Glaucoma patients had considerably better knowledge of the disease (p < 0.01) than did nonglaucoma patients. Younger patients were significantly better informed than older ones (p < 0.01). Nonglaucoma patients with a positive diagnosis of glaucoma among their circle of friends or family were significantly better informed (p < 0.01) than those without such persons in their circle of friends. CONCLUSION: Persons with glaucoma are much better informed about the disease than nonglaucoma patients, but the general level of knowledge is very low. Notably, younger patients were better informed than older ones. The present study, comprising a large number of patients, revealed poor knowledge of glaucoma among patients with the disease and especially among nonglaucoma patients in Vienna.
