Dry Eye and Visual Display Terminal-Related Symptoms among University Students during the Coronavirus Disease Pandemic.

Purpose: To evaluate dry eye (DE) and subjective visual display terminal (VDT)-related symptoms in university students who moved their classes online due to the COVID-19 pandemic.

Methods: Cross-sectional study of students who were taking online classes. In May 2020, the participants completed a Dry Eye Questionnaire (DEQ-5) and a self-report survey, which included demographics, medical history, information on the use of VDT and presence of VDT-related symptoms.

High frequency of digital eye strain and dry eye disease in teleworkers during the coronavirus disease (2019) pandemic.

This study aimed to evaluate visual display terminal (VDT)-related digital eye strain (ES) and dry eye disease (DED) symptoms in subjects whose work was changed to teleworking (TW) during the coronavirus pandemic. A digital self-reported survey was conducted on subjects in TW, including demographics, medical history, VDT time and ES-related symptoms before and during the pandemic and DED (dry eye questionnaire 5 [DEQ-5] questionnaire). A total of 1797 questionnaires were analyzed.

High prevalence of Demodex spp. infestation among patients with posterior blepharitis: correlation with age and cylindrical dandruff.

Objective: To determine prevalence of Demodex spp. and infestation index (II) by the parasite among patients of different ages with blepharitis and to assess association with occurrence of cylindrical dandruff (CC).

Materials And Methods: Prospective study including patients diagnosed with posterior blepharitis between 2013 and 2015, without previous acaricide treatment, was conducted by Fundación Oftalmológica Los Andes (Chile).

Algorithm approach for revision surgery following late-onset bleb complications after trabeculectomy: long-term follow-up.

Purpose:: The aim of this study was to introduce a reproducible algorithm for the surgical management of late-onset (>2 months) bleb complications after trabeculectomy with mitomycin C.

Methods:: We performed a retrospective review of eyes treated using a reproducible algorithm approach by a single surgeon for the surgical management of late-onset bleb complications from July 2006 to April 2014. Exclusion criteria were bleb revision with less than 3 months of follow-up or bleb revision combined with other glaucoma procedures at the time of surgery.

Zone I of Tear Microdesiccates Is a Lipid-Containing Structure.

Purpose: Morphological features of tear microdesiccates on glass surfaces have been associated with tear fluid status. Tear-film lipids play a critical role in the pathophysiology of some ocular surface disorders. Tear microdesiccates display 4 distinctive morphological domains (zones I, II, III, and transition band).
