3%) with calcium score greater than 0, p = 0.75. Ionomycin However, occlusion was more frequent in patients with calcium, whereas wall thickening was in those without calcium.
Aortic calcification in TA is related to age, evolution time, and abnormalities in lipid profile and occlusion and, inversely with some activity scores. Identification of calcification could be useful in identifying patients that even without significant lesions might have accelerated atherosclerosis, and who might be benefited with specific treatment.

To report a case of microsporidia (Encephalitozoon hellem) keratoconjunctivitis acquired through avian transmission in an immunocompetent adult, diagnosed by metagenomic deep sequencing (MDS), and confirmed by polymerase chain reaction.
A case report.
An 18-year-old woman was referred with unilateral keratoconjunctivitis unresponsive to topical and systemic therapy after exposure to birdcage debris. Slit-lamp examination of the left eye revealed a follicular papillary reaction of the palpebral conjunctiva and multiple corneal punctate epithelial opacities that stained minimally with fluorescein. In vivo confocal microscopy revealed bright double-walled structures and smaller bright round structures in the superficial epithelial debris and epithelium. Molecular diagnosis with MDS of E. hellem was confirmed by polymerase chain reaction. Clinical resolution and normalization of in vivo confocal microscopy was observed after a 6-week course of topical azithromycin. The patient elected a 3-week course of topical voriconazole 1% for definitive antimicrosporidial treatment, with no evidence of persistent infection 1 month later.
Microsporidial (E. hellem) keratoconjunctivitis can occur through avian transmission in immunocompetent hosts. Topical azithromycin may be effective against this pathogen. MDS has utility in the diagnosis of atypical keratoconjunctivitis.

To confirm the ocular tropism of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by evaluating the expression of viral entry factors in human ocular tissues using immunohistochemistry.
Fresh donor corneas and primary explant cultures of corneal, limbal, and conjunctival epithelial cells were evaluated for the expression of viral entry factors. Using immunohistochemistry, the samples were tested for the expression of angiotension-converting enzyme 2 (ACE2), dendritic cell-specific intracellular adhesion molecule 3-grabbing nonintegrin (DC-SIGN), DC-SIGN-related protein (DC-SIGNR), and transmembrane serine protease 2 (TMPRSS2).
In total, 5 donor corneas were evaluated for the expression of viral entry factors. In all specimens, both ACE2 and TMPRSS2 were expressed throughout the surface epithelium (corneal, limbal, and conjunctival) and corneal endothelium. In corneal stromal cells, ACE2 was sporadically expressed, whereas TMPRSS2 was absent. DC-SIGN/DC-SIGNR expression varied between donor sal transplantation cannot be ruled out, given the presence of ACE2 in corneal epithelium and endothelium. Cultured corneal, limbal, and conjunctival epithelial cells mimic the expression of viral entry factors in fresh donor tissue and may be useful for future in vitro SARS-CoV-2 infection studies.
A consecutive case series of patients with dupilumab-associated ocular surface disease (DAOSD) that describes common ocular symptoms and signs, proposes a symptom disease severity grading system, and describes treatment strategies of DAOSD patients was evaluated.
A retrospective chart review of patients with concomitant dupilumab-treated atopic dermatitis and DAOSD with ophthalmic evaluation between January 2014 and May 2019 was conducted.
Twenty-nine patients (mean age 46 years, M/F 12/17) with 57 ophthalmic exams were identified. The most common ocular symptoms included irritation/pain (n = 28, 97%), redness (n = 24, 83%), pruritus (n = 18, 62%), discharge (n = 18, 62%), and light sensitivity (n = 6, 21%). The most frequent signs included conjunctival injection (n = 18, 62%), superficial punctate keratitis (n = 16, 55%), and papillary reaction (n = 8, 28%). Topical corticosteroids (TCS) (n = 23, 79%), tacrolimus (n = 6, 21%), and artificial tears (n = 7, 24%) were the most commonly used therapies. Of se a symptom-based grading system that can guide nonophthalmic physicians regarding ophthalmology consult.
Meibomian glands are subject to regulation by sex hormones. We have now investigated the possible relation between benign prostate hyperplasia (BPH) and meibomian gland dysfunction (MGD).
Men diagnosed with BPH and receiving treatment with tamsulosin and age-matched male control subjects who attended Itoh Clinic, Saitama, Japan, were enrolled. An ocular symptom score, lid margin abnormality score, and superficial punctate keratopathy score as well as the meiboscore (0-6), meibum grade, breakup time of the tear film, and Schirmer test values were evaluated. Male pattern baldness was also graded according to the Hamilton-Norwood scale.
Forty-four eyes of 44 men with BPH (mean age ± SD, 76.1 ± 2.2 years) and 46 eyes of 46 control subjects (mean age ± SD, 75.3 ± 6.2 years) were enrolled. The meiboscore in the BPH group (4.5 ± 1.4) was significantly higher than that in the control group (1.8 ± 1.5, P < 0.0001). Breakup time of the tear film was significantly shorter (3.6 ± 1.7 vs. 5.6 ± 2.5 seconds, P < 0.0001), and Schirmer test value was significantly smaller (9.8 ± 4.8 vs. 13.3 ± 8.0 mm, P = 0.048) in the BPH group than that in the control group. Other ocular parameters did not differ significantly between the 2 groups. The proportion of men with androgenic alopecia was also higher in the BPH group than that in the control group.
BPH was associated with meibomian gland loss and instability of the tear film as well as with the presence of androgenic alopecia.

To evaluate the safety and efficacy of corneal minimized-volume ablation with accelerated cross-linking in improving visual function in keratoconus eyes.
Through a pilot study, 25 eyes of 25 consecutive patients with keratoconus grade I-III were recruited that underwent corneal transepithelial photorefractive keratectomy with "minimized volume" ablation profile and accelerated corneal cross-linking in the same session. Corrected and uncorrected distance visual acuities, manifest refraction, corneal curvature and higher-order aberrations, endothelial cells, and the ocular modulation transfer function were assessed preoperatively and postoperatively, with a minimum follow-up of 6 months. A P value < 0.05 was the threshold of statistical significance.
At 8.2 ± 3.6 months postoperatively, the mean corrected and uncorrected distance visual acuities (LogMAR) were 0.07 ± 0.15 and 0.45 ± 0.39, significantly improving from the baseline of 0.24 ± 0.24 (P8m-before = 0.005) and 1.12 ± 0.33 (P8m-before < 0.001rovement of visual function in patients with keratoconus.
Corneal minimized-volume ablation with accelerated cross-linking was an effective and safe option for correction of mild refractive error, leading to significant improvement of visual function in patients with keratoconus.
To describe a simple finding that can be used to determine donor tissue orientation in Descemet membrane endothelial keratoplasty (DMEK). This involves the appearance of a highly reflective round curved line from an overlapping graft edge within the anterior chamber using light from an endoilluminator. We here name this Kobayashi sign (K-sign).
Twelve consecutive eyes from 12 patients who underwent DMEK were evaluated for the presence of a K-sign. The presence of Berrospi sign (B-sign), a double-line reflection from the peripheral curls of the Descemet membrane (DM) roll that has been reported to be useful for correct graft orientation, was also evaluated.
Of 12 cases, 3 donors showed a loosely scrolled roll soon after DM donor insertion; all 3 of these showed a positive B-sign only when the endoilluminator was used. Nine donors showed a tightly scrolled DM roll without a B-sign; among these 9 donors, a K-sign was visible in 7 cases only when the endoilluminator was used. The remaining 2 cases with a tight scroll configuration showed no K-sign even with the use of endoillumination, indicating that the roll edge was located completely downward; rotation of the roll using a small jet of fluid from paracentesis revealed K-sign in these cases.
This technique is useful for determining the correct orientation of a tightly scrolled DM roll, subsequently enabling rapid DMEK surgery. For loosely scrolled DM roll, endoillumination enhanced B-sing is proven useful.

The safety of KPI-121 0.25%, an ophthalmic nanoparticle suspension of loteprednol etabonate, was evaluated in subjects with dry eye disease (DED) in one phase 2 and three phase 3 randomized trials of similar design.
Adults with DED received KPI-121 0.25% or vehicle drops 4 times daily (QID) for ≥2 weeks; 1430 subjects received KPI-121 0.25% and 1438 subjects received vehicle drops. Main safety assessments were adverse events (AEs) and intraocular pressure (IOP). As a common side effect associated with the use of ocular corticosteroids is elevated IOP, subjects with a history of or current diagnosis of glaucoma were excluded.
Instillation site pain was the most common AE, reported by 5.2% of subjects in the KPI-121 0.25% group and 4.4% of subjects in the vehicle group; other AEs were reported by ≤0.8% of subjects in the KPI-121 group. IOP elevations, a side effect associated with the use of ophthalmic corticosteroids, were observed with low incidence 0.6% and 0.2% of subjects in the KPI-121 and vehicle groups, respectively. An IOP elevation was defined as an increase from baseline of >5 mm Hg that resulted in an IOP of ≥21 mm Hg in either eye during use of the study product.
KPI-121 ophthalmic suspension 0.25% seemed to be safe and well tolerated when dosed QID for 2 to 4 weeks in those DED subjects included in the 4 trials.

To describe a case of nivolumab-induced ulcerative keratitis rapidly recovering on topical steroid treatment and to determine changes in cytokine levels in the tear fluid caused by nivolumab.
We report a 34-year-old man receiving nivolumab for metastasized melanoma with severe dry eye symptoms and a persistent corneal epithelial defect. Levels of cytokine and matrix metalloproteinase in tear fluid were measured by multiplex immunoassays.
The corneal epithelial defect failed to recover for antiviral and lubrication therapy but resolved within 48 hours after topical steroid therapy was initiated. No recurrence of corneal ulceration was observed with intermittent topical steroid therapy during the remaining period of nivolumab treatment. No Sjögren disease-related autoantibodies were detected in the patient's serum. The levels of inflammatory cytokines and matrix metalloproteinases in the tear fluid were markedly elevated after nivolumab treatment.
Our observations suggest that nivolumab treatment induces a local autoimmune ocular surface disorder resulting in corneal ulceration that promptly resolves using steroid eye drops.
