ABSTRACT.Purpose: To report nine cases of external ophthalmomyiasis caused by Dermatobia hominis. Methods: Retrospective, non-comparative, interventional case series. Participants consisted of patients (n = 9) presenting at Cayenne Hospital between 1968 and 2003. The location and number of larvae, the larval stage, and the medical and surgical procedures applied were studied in each case. Results: Seven patients had palpebral myiasis (including one with three larvae) and two had conjunctival myiasis. Every patient had palpebral oedema. The larval respiratory pore was located on the palpebral skin or free margin or on the conjunctiva. Movements were present within the lesion in at least three patients. Petroleum ointment or ivermectine solution was used in at least four patients to smother or kill the larvae. Extraction under local anaesthesia was possible in six patients, while three required general anaesthesia. Conclusion: Several larvae may be present in a patient. Topical ivermectine may help to kill the larvae before extraction is attempted.

The worst ocular lesions are chemical burns caused by strong bases and acids. Associated with the destruction of limbal stem cells (LSCs), there are repeated epithelial ulcerations, chronic stromal ulcers, deep stromal neovascularisation, conjunctival invasion and even corneal perforations. The initial clinical examination is difficult because the symptomatology is severe, but nevertheless it helps to classify the lesions, to establish a prognosis and to guide the therapeutic care. The classification system used most is that implemented by Hughes and modified by Roper-Hall. It is now completed neatly by those proposed by Dua and Wagoner, which are based on the importance of the deficit of LSCs. Prognosis of severe forms has progressed significantly thanks to a better knowledge of the physiology of the cornea’s epithelium. Surgical techniques to repair destroyed LSCs have changed the prognosis of severe corneal burns significantly. To limit the incidence of burns, prevention, especially in the industrialised world, is essential.

We report the case of a 10-year-old boy with acute-onset diplopia and ptosis in the right eye. CR was positive for SARS-CoV-2. The patient was managed successfully with corticosteroids. We highlight the need for heightened suspicion of occult COVID-19 infection among children presenting with unusual III nerve palsy.
