Allergic conjunctivitis is the direct exposure of ocular mucosal surfaces to the environment that causes an immediate hypersensitivity reaction in which triggering antigens couple to reaginic antibodies (IgE) on the cell surface of mast cells and basophils, leading to the release of histamines that causes capillary dilation and increased permeability and thus conjunctival injection and swelling.
Nerve endings are also stimulated causing pain and itching.
Seasonal allergic conjunctivitis is the most common form in temperate climates. It usually occurs and recurs at a certain period of the year and subjectively more severe than perennial allergic conjunctivitis.
Perennial allergic conjunctivitis manifests and recurs throughout the year with no seasonal predilection. It is most common in tropical climates.
During the Kuala Lumpur International Neonatology Conference held in conjunction with the World Prematurity Day 2017, Dato Dr Musa Mohd Nordin spoke on the importance of immunizing children with the diphtheria-tetanus-acellular pertussis-inactivated poliovirus-Haemophilus influenzae type b (DTaP-IPV-Hib) vaccine. He highlighted the role of Hexaxim® as a fully liquid, ready-to-use, 6-in-1 (including hepatitis B) vaccine for the primary and booster vaccinations of infants and toddlers. Meanwhile, Dr Yong Junina Fadzil discussed the benefits of quadrivalent influenza vaccines (QIVs) in providing children with broader protection against influenza B viruses.
