Abstract
Heparin has been used extensively as an antithrombotic and anticoagulant for close to 100 years. This anticoagulant activity is attributed mainly to the pentasaccharide sequence, which potentiates the inhibitory action of antithrombin, a major inhibitor of the coagulation cascade. More recently it has been elucidated that heparin exhibits anti-inflammatory effect via interference of the formation of neutrophil extracellular traps and this may also contribute to heparin's antithrombotic activity. This illustrates that heparin interacts with a broad range of biomolecules, exerting both anticoagulant and nonanticoagulant actions. Since our previous review, there has been an increased interest in these nonanticoagulant effects of heparin, with the beneficial role in patients infected with SARS2-coronavirus a highly topical example. This article provides an update on our previous review with more recent developments and observations made for these novel uses of heparin and an overview of the development status of heparin-based drugs. SIGNIFICANCE STATEMENT: This state-of-the-art review covers recent developments in the use of heparin and heparin-like materials as anticoagulant, now including immunothrombosis observations, and as nonanticoagulant including a role in the treatment of SARS-coronavirus and inflammatory conditions.

Ocul Surf 2021; 21:66-77. [PMID: 34000363 DOI: 10.1016/j.jtos.2021.05.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 05/11/2021] [Accepted: 05/12/2021] [Indexed: 11/30/2022]
Abstract
Conjunctival hyperemia is one of the most common causes for visits to primary care physicians, optometrists, ophthalmologists, and emergency rooms. Despite its high incidence, the treatment options for patients with conjunctival hyperemia are restricted to over-the-counter drugs that provide symptomatic relief due to short duration of action, tachyphylaxis and rebound redness. As our understanding of the immunopathological pathways causing conjunctival hyperemia expands, newer therapeutic targets are being discovered. These insights have also contributed to the development of animal models for mimicking the pathogenic changes in microvasculature causing hyperemia. Furthermore, this progress has catalyzed the development of novel therapeutics that provide efficacious, long-term relief from conjunctival hyperemia with minimal adverse effects.

Abstract
PURPOSE To report a case of amiodarone-induced vortex keratopathy-associated anatomical findings and subjective visual perception before and after treatment with topical heparin eye drops. METHODS Case report. RESULTS A 76-year-old man complained of halos in his vision in both his eyes due to prominent bilateral cornea verticillata. For treatment of cornea verticillata, we prescribed unpreserved eye drops of a sterile, phosphate-free solution of 0.1% sodium hyaluronate with 1300 IU/mL heparin sodium 3 times daily to the left eye, whereas the other side served as the control. The area of corneal deposits was measured by 2 examiners before and at the 1- and 3-month examination. At last follow-up, cornea verticillata had been reduced from 6 to 2 mm in area by approximately 66% from grade-III to grade-II amiodarone keratopathy. CONCLUSIONS In patients using amiodarone, clearing of cornea verticillata may be achieved by topical use of unpreserved eye drops of a sterile, phosphate-free solution of 0.1% sodium hyaluronate with 1300 IU/mL heparin sodium.
