Allergic conjunctivitis is an increasingly frequent condition with a higher prevalence in children. It can be debilitating and is responsible for a great economic burden. These guidelines were developed on the basis of the medical literature (PubMed/Medline database) and the experience of an Expert Committee composed of members of the Brazilian Society of Pediatric Ophthalmology, the Brazilian Council of Ophthalmology, the Brazilian Society of Pediatrics, and the Brazilian Association of Allergy and Immunology. Allergic conjunctivitis is considered to be controlled when the ocular symptoms are not uncomfortable or are present, at most, on 2 days a week; the visual analog scale score is below 5; and the degree of conjunctival hyperemia is graded 0 or 1 on the Efron scale. Allergic conjunctivitis should be classified as mild, moderate, severe, and vision-threatening for adequate treatment and monitoring of frequency. The present document is a guideline for diagnosing, treating, and monitoring pediatric allergic conjunctivitis considering the clinical and demographic aspects of allergic conditions in Brazil.

The aim of this study was to evaluate the corneal posterior curvature changes after phacoemulsification cataract surgery, with intraocular lens implantation, with a temporal limbal self-sealing 2.75 millimeters (mm) corneal incision, using a Placido-dual rotating Scheimpflug device. In this prospective intervention study, corneal posterior curvature changes were evaluated in fifty-six patients (56 eyes). All patients underwent corneal tomography using the Galilei G2 (Ziemer Ophthalmic System AG, Port, Switzerland) preoperatively (PRE) and with two weeks (RP15), one month (RP30), and three months (RP90) after phacoemulsification cataract surgery with a temporal limbal self-sealing 2.75 mm incision. Tomographic parameters analyzed in the posterior cornea were the steep curvature (K2), flat curvature (K1), mean curvature (average K), and posterior corneal astigmatism. We did not observe any statistically significant change in the K2, K1, average K, and posterior corneal astigmatism in any postoperative follow-up measurements (RP15, RP30, RP90), showing that the postoperative values tend to be the same as the preoperative ones when measured with the Galilei G2 tomography. In conclusion, the 2.75 mm temporal limbal self-sealing corneal incision in phacoemulsification cataract surgery does not induce significant changes in the posterior corneal curvature parameters of K2, K1, average K, and astigmatism., Competing Interests: Ethical issues have been completely observed by the authors.
