Use of Crossed Polarizers to Enhance Images of the Eyelids

Conclusions: The use of Crossed Polarizers in imaging the external eye reduces reflections and glare from the eyelid skin and margins, thereby allowing for a more detailed evaluation of underlying structures and analysis of images. These findings suggest that including Crossed Polarizers in clinical photography has informative applications for assessing eyelid disease.

Conclusions: Tsukamurella tyrosinosolvens and Tsukamurella pulmonis were found to be the predominant species that caused ocular infection. Ocular manifestation of Tsukamurella has a wider spectrum than that previously reported. A high-level of suspicion and a low threshold for microbiological sampling in cases with prolonged ocular surface infection are recommended to diagnose Tsukamurella infections.

AbstractPurpose of ReviewThe human body lives in a symbiotic relationship with the bacteria, viruses, fungi, and protozoa that make up the microbiome. In this review, we discuss the compositions of the gut and ocular surface microbiomes in relationship to health and disease.Recent FindingsThe gut microbiome is dominated by Firmicutes, whereas the ocular surface is dominated by Proteobacteria. The compositions of the microbiome are similar between individuals at the phyla level, but differ at the genus level. Alterations in the microbiome have been associated with disease. For example, ocular diseases such as uveitis, dry e...

CONCLUSION: Coagulase-negative Staphylococcus and Staphylococcus aureus were the most isolated bacteria in patients affected by blepharitis in our tertiary eye centre. Both bacteria were resistant to erythromycin. Through the years, it seems that coagulase-negative Staphylococcus gained resistance to penicillin, erythromycin, ciprofloxacin and rifampicin.

Demodex mites are commonly found on the periocular skin and eyelashes, with increasing rates observed with age. [1,2] However, these microscopic ectoparasites found on the skin of healthy asymptomatic humans have also been shown to have pathogenic potential [3,4]. Demodex have been associated with anterior and posterior blepharitis, disorders of the eyelashes, keratoconjunctivitis and contact lens wear. [1,5] Furthermore, ocular discomfort has been also been associated with higher Demodex counts.

CONCLUSION: We reported the efficiency of the different treatments of Demodex blepharitis. Because of less systemic side effects, local treatments seem promising molecules in the treatment of Demodex blepharitis. PMID: 31229586 [PubMed - as supplied by publisher]

Conclusion: Microbial keratitis can affect those with OSD. In our setting, CoNS were the main organisms identified. Furthermore, patients prescribed a combination therapy of fortified antibiotics had poorer outcomes compared to monotherapy fluoroquinolones. PMID: 31189397 [PubMed - as supplied by publisher]

ConclusionOcular manifestations are significant in patients with RA. The most common ocular manifestation is dry eye. Ocular manifestations are significantly associated with the disease duration and should be expected regardless of disease activity in RA patients.

Authors: Moris García V, Valenzuela Vargas G, Marín Cornuy M, Aguila Torres P Abstract Demodex folliculorum and Demodex brevis are ectoparasites that inhabit the skin of humans. They have been related to alterations in the ocular surface, such as, dysfunction of Meibomian glands, blepharitis, chalazion, etc. Ocular demodicosis is characterised by the pathognomonic presence of cylindrical dandruff at the base of the eyelashes, and various symptoms including, among others, itching, lacrimation, and hyperaemia. A bibliographic review was carried out on the role of Demodex spp. in ocular disease, includin...
