  • Toxic Keratopathy Following the Use of Alcohol-Containing Antiseptics in Nonocular Surgery
    Research Brief Report Toxic Keratopathy Following the Use of Alcohol-Containing Antiseptics in Nonocular Surgery Hsin-Yu Liu, MD; Po-Ting Yeh, MD; Kuan-Ting Kuo, MD; Jen-Yu Huang, MD; Chang-Ping Lin, MD; Yu-Chih Hou, MD IMPORTANCE Corneal abrasion is the most common ocular complication associated with nonocular surgery, but toxic keratopathy is rare. OBSERVATION Three patients developed severe toxic keratopathy after orofacial surgery on the left side with general anesthesia. All patients underwent surgery in the right lateral tilt position with ocular protection but reported irritation and redness in their right eyes after the operation. Alcohol-containing antiseptic solutions were used for presurgical preparation. Ophthalmic examination showed decreased visual acuity ranging from 20/100 to 20/400, corneal edema and opacity, anterior chamber reaction, or stromal neovascularization in the patients’ right eyes. Confocal microscopy showed moderate to severe loss of corneal endothelial cells in all patients.

  • Overflow Tearing in Infants
    The Tearing Patient: Diagnosis and Management Written By: Kristina M. Price, MD, and Michael J. Richard, MD Edited by Ingrid U. Scott, MD, MPH, and Sharon Fekrat, MD Excessive tearing, also known as epiphora, is due to a disruption in the balance between tear production and tear loss. Numerous etiologies lead to an excess of tears, and there are a number of ways to diagnose and treat this condition. Currently, there is not a firm consensus on the best way to evaluate the tearing patient. However, a simple algorithm may aid the general ophthalmologist in the evaluation and management of this common condition. Anatomy and Physiology of the Lacrimal System The main lacrimal gland, the accessory lacrimal glands and the conjunctival epithelium are responsible for producing tears. Tears are spread over the surface of the eye by blinking to establish the precorneal tear film. Each contraction of the orbicularis muscle helps move the tears across the ocular surface toward the lacrimal drainage system. Ideally, the basal tear secretion rate equals the rate of tear drainage and evaporation. Basal tear secretion occurs at a rate of about 1.2 µl/minute, although reflexive tear secretion can increase this up to 100-fold. Tears enter the puncta at a rate of 0.6 µl/min; about 90 percent are reabsorbed through the nasolacrimal duct mucosa and 10 percent drain into the floor of the nasal cavity. Tears evaporate from the ocular surface at a variable rate, but ideally tear evaporation roughly equals the difference between basal secretion and drainage. The ocular surface (including the lacrimal lakes in the conjunctival fornices, the marginal tear strip and the precorneal tear film) can hold only 8 µl of tears at any time.
