“…After discontinuation of the ointments, there was no recurrence of dermatitis. A previously reported case demonstrated severe Paederus -associated keratitis requiring corneal transplantation, with poor prognosis (6/60) [ 4 ]. Thus, an accurate initial diagnosis and proper usage of steroids with adequate clinical examinations and investigations are necessary for achieving a better visual outcome, as steroid use may inhibit corneal epithelization.…”

“…Symptoms typically appear after a moderate interval of 12-48 h from contact with pederin, making it challenging for doctors to identify the underlying cause of a patients' dermatitis [1]. Many cases of contact dermatitis caused by P. fuscipes have been reported because of its broad prevalence [2][3][4][5]. However, few reports have described the ocular toxicity of the Paederus species, which presents as conjunctivitis and keratitis [6][7][8][9].…”

Toxicity of Paederus species to eyes has scarcely been reported. This report presents a case of chemical blepharokeratoconjunctivitis with delayed re-epithelialization caused by Paederus fuscipes in a patient with dry eye after laser-assisted in situ keratomileusis (LASIK). A 47-year-old woman who had undergone LASIK for myopia 10 years prior experienced visual disturbance and pain in her left eye after being hit by a P. fuscipes insect in her eye 1 day prior to evaluation. At the initial presentation, dermatitis around the patient’s left eye, eyelid oedema, conjunctival chemosis, corneal epithelial defects, and a best corrected visual acuity (BCVA) of 20/200 were noted. No gram-positive/negative bacteria or indication of cellulitis/elevated inflammation was detected. Administration of topical steroids (betamethasone) and antibiotics (topical: cefmenoxime and levofloxacin; intravenous: ceftriaxone) improved the non-infectious chemical blepharokeratoconjunctivitis; however, the large corneal epithelial defect remained for 10 days. Switching from betamethasone to a preservative-free form facilitated re-epithelialization, and the patient’s BCVA improved to 20/16 after 2 months. Ophthalmologists should consider the toxicity of the Paederus species on the ocular surface and eyelid.

“…Several authors have reported cases of Paederus dermatitis, with ocular involvement in the form of Nairobi eye in various percentages [ 9 , 10 , 11 , 12 ]. Tiwari et al [ 13 ] described a case of a peripheral ulcerative keratitis after the removal of a corneal foreign body, which seemed to be the shell of an insect; the patient's condition worsened to a total corneal abscess and ended as penetrating keratoplasty.…”

We report a case of ocular injury caused by a bombardier beetle in a young boy. Ocular injuries due to this coleoptera have not previously been reported. An 11-year-old boy experienced an eye injury while trying to place a bombardier beetle inside an anthill. The boy was diagnosed with a second-degree burn on the skin of the upper right eyelid and conjunctival and corneal erosion in the right eye. The condition resolved completely after 2 weeks of appropriate treatment. Education about the dangers of playing with insects is crucial to prevent this type of lesions.

Purpose: To report an uncommon case in which an insect foreign body (FB) in the cornea induced severe marginal ulcerative keratitis. Methods: The insect body was removed during an eye examination. A shaped deep lamellar keratoplasty was then performed on the ulcerous corneal tissue and pseudopterygium. The insect FB was identified as a member of the nontoxic Diptera insect order, belonging to either the Chloropidae or Sphaeroceridae family. Results: The patient recovered well after the keratoplasty, and her corneal graft was clear with significantly improved visual acuity after 2 months. Conclusions: Long-time retention of a nontoxic insect FB in the cornea could induce severe noninfectious keratitis. Individually designed deep lamellar keratoplasty successfully restored the transparency of the cornea and visual function.
