The aim of this study is to describe the involvement of Epstein–Barr Virus (EBV) in the diseases of the ocular anterior segment. This is a narrative review designed using the PUBMED, SCOPE and Web of ...Science databases, searching for reported literature on findings in the anterior ocular segment related to EBV between 1990 and 2020. Epstein–Barr Virus (EBV) is implicated in the development of salmon‐coloured conjunctival masses in the context of acute mononucleosis and lymphoproliferative disorders. Moreover, EBV can cause haemorrhagic conjunctivitis and its corneal implications appear as different types of keratitis patterns. The involvement of EBV in the pathogenesis of anterior segment inflammation is not well‐defined. Current evidence regarding anterior segment disease caused by EBV infection has been proved by positive viral detection through polymerase chain reaction test in eyes with lymphoproliferative disorders known to be caused by EBV, as B‐ and NK/T‐cell lymphoid tumours. Antiviral treatment (oral Aciclovir or Valaciclovir) in anterior segment disease caused by EBV remains controversial.
Purpose
To measure the effects of Autologous serum (AS), Allogeneic Serum (HS) and Umbilical Cord serum (CS) eye drops in severe dry eye disease (DES), as well as to characterize and quantify several ...molecules in the three sera (albumin, fibronectin; Vitamin A and E; IgG, IgA and IgM; Transforming growth factor β; Epithelial growth factor).
Methods
Randomized, double‐blind, single‐centre, three‐arm (AS, HS and CS) clinical trial. Sixty‐three subjects were included with severe DES, 21 in each arm of the study. Visual acuity, Schirmer test, Breakup time (BUT), lissamine green, fluorescein staining measurements and a questionnaire were performed prior to treatment, and after one‐month and three‐month follow‐up.
Results
There was a significant main effect of time on visual acuities, Schirmer and BUT tests and fluorescein and lissamine green staining measurements and questionnaire scores (p = 0.015, p = 0.002, p < 0.001, p < 0.001, p = 0.031 and p < 0.001, respectively), although there was no significant interaction between time and serum type, nor between serum type and the test performed. Regarding the concentration of molecules, in our study AS contained significantly higher concentrations of IgA, IgG and fibronectin whereas HS contained significantly higher concentration of IgM, vitamins A and E, TGF and albumin. Contrary to previous reports, CS did not show higher concentration of any of the molecules analysed.
Conclusions and relevance
The three sera were effective in the treatment of severe DES. CS did not contain a higher proportion of molecules compared to AS/HS. More research is needed to assess the effect of AS in patients with DES and autoimmune diseases.
Purpose
To describe paediatric keratoconus (KC) patients by tomographic and aberrometric characteristics at first diagnosis, in a multicentre study.
Methods
We included 278 eyes from 139 paediatric ...patients, with a first tomographic diagnosis (Pentacam®) of KC prior to 18 years old. KC classification was based on the KC Index (≥ 1.07) and Topographic Keratoconus Classification (TKC ≥ 1). Patients were divided based on age ranges (14 and under and over 14 years) and gender. Statistical analysis was performed with SPSS statistics 25.0. ANOVA factor was carried out comparing to compare groups.
Results
278 eyes were screened, and 230 eyes were diagnosed with paediatric KC. Mean age was 15.48 ± 2.33 (6 to 18) years. We found differences in terms of TKC (2.08 ± 0.89 and 2.38 ± 0.82, p < 0.05) and spherical aberration (−0.71 ± 0.97 and −1.07 ± 1.36, p < 0.05) among the 14 years old or under and above 14 years old groups, respectively. Overall, female paediatric KC patients presented a more severe TKC, Belin Ambrosio Display, maximum keratometry, asphericity and primary and secondary coma aberrations compared to male KC patients. We observed a correlation between CDVA and asphericity (r = 0.71, p < 0.01), as well as between CDVA and spherical aberration (r = 0.69, p < 0.01).
Conclusion
Our findings revealed that the debut of KC is usually in a moderate to advanced stage in the paediatric population at first diagnosis, particularly in female patients. Corneal tomography should be systematically performed in children with recent onset of corneal astigmatism.

The incidence and impact of ocular side effects in patients treated with checkpoint inhibitors are not clearly defined.
We reviewed prospective phase III clinical trials of checkpoint inhibitors ...applied in lung cancer, renal cell cancer, and melanoma. Case reports of the occurrence of ocular toxicities in patients receiving immune checkpoint inhibitors were also included. Of the 35 articles corresponding to phase III clinical trials with checkpoint inhibitors, ocular toxicity was described in four. Forty-six clinical cases of ocular toxicity after therapy with checkpoint inhibitors have been reported. The most frequently described ocular toxicities are uveitis, inflammatory orbital disease, and alterations of the ocular surface. Ocular toxicity is underestimated in checkpoint inhibitors clinical trials. Early ophthalmic examination and treatment with corticosteroids may improve the visual prognosis in these patients.

Journal Article
Our objective is to analyze retinal changes using optical coherence tomography angiography (OCT-A) in patients with mild cognitive impairment (MCI) to characterize structural and vascular ...alterations. This cross-sectional study involved 117 eyes: 39 eyes from patients with MCI plus diabetes (DM-MCI), 39 eyes from patients with MCI but no diabetes (MCI); and 39 healthy control eyes (C). All patients underwent a visual acuity measurement, a structural OCT, an OCT-A, and a neuropsychological examination. Our study showed a thinning of retinal nerve fiber layer thickness (RNFL) and a decrease in macular thickness when comparing the MCI-DM group to the C group (p = 0.008 and p = 0.016, respectively). In addition, an increase in arteriolar thickness (p = 0.016), a reduction in superficial capillary plexus density (p = 0.002), and a decrease in ganglion cell thickness (p = 0.027) were found when comparing the MCI-DM group with the MCI group. Diabetes may exacerbate retinal vascular changes when combined with mild cognitive impairment.
To assess which signs and eye prosthesis care habits are related to subjective discomfort in patients with dry anophthalmic socket syndrome (DASS), using standardized tools from daily practice.
62 ...anophthalmic sockets were compared with their healthy fellow eye using the Standard Patient Evaluation of Eye Dryness (SPEED) score. The correlations between SPEED questionnaire and the prosthesis care, discharge characteristics score, conjunctival inflammation score, meibomian gland dysfunction (MGD) scores and Schirmer I test were studied.
The anophthalmic sockets group achieved a higher SPEED test score (p < 0.01), discharge score (p < 0.01), conjunctival inflammation score (p < 0.01), MGD scores (p < 0.01) and lower Schirmer I test (p < 0.01) compared with their fellow, healthy eye. Patients with a prosthesis replacement of one year or less, those with a current fit time of one year or less and those with a cleaning frequency above one month reported better SPEED, (p < 0.01), conjunctiva inflammation (p < 0.01) and MGD scores (p < 0.01).
Most anophthalmic patients suffer mild to severe DASS, which seems related to discharge, conjunctival inflammation and MGD. Moreover, certain practices related to the care of the prosthesis such as replacing with a frequency lower than yearly, current fitting time inferior to one year and a removing and cleaning regime above one month, were related to a lower discomfort sensation, conjunctival inflammation and MGD. Clinicians should consider the DASS when facing patients with anophthalmic socket and discomfort symptoms.
