Dear Dr. Sutton,

Re: Urgent Referral for Mr. Charlie Lynn, DOB 14-1-1945I am referring Mr. Lynn, a 65 year Australian man who is a member of NSW parliament, and operates a Kokoda trekking expedition in PNG, for further management of presumed acanthamoeba vs bacterial keratitis in both eyes

Mr. Lynn presented to our clinic this morning with a two day history of severe pain, redness and poor vision in both eyes. He is a myope who uses extended wear ( monthly disposable) soft contact lenses when he comes up to Kokoda for the expeditions four times a year, for many years now and gives a history of bathing in the river without removing his contact lenses!

He reported that he developed severe pain in both eyes 2 days prior to presentation following his evening wash in the river. He had come into close contact with a local person with presumed “red eyes” the samaday_Unfortunately, he did not remove his contact lenses which he had been wearing for past 5 days, for another 24 hours until his symptorrs got worse.

He then removed the contact lenses and the eyes were patched with antibiotic eye ointment for a whole day before we saw him. He was started on Flucloxacillin and Nurofen by a doctor on the expedition.

His past ocular history is significant for excision of a left lower lid benign skin lesion . There is no history of “cold sores” or any eye infection or inflammation. He is otherwise in good health and has no known drug allergies.

On examination, his visual acuity was hand movement in the RE and counting fingers at½ m in the LE. He was in pain and was extremely photophobic. Pupils were normal. There was diffuse conjunctiva! hyperemia in both eyes. The corneas in both eyes were 80% denuded of their epithelium with large central epithelial defects about 8 mm in size. Corneal stroma was clear and compact. There were no infiltrates in the stroma in both eyes. The endothelium was coated with inflammatory exudates from hypopyon (20%) in the anterior chambers of both eyes. The anterior chamber was deep and the pupil was round. There was 2 + nuclear sclerosis in both lenses.

My clinical working diagnosis was of bilateral acanthmoeba keratitis or some form of severe epithelial bacterial keratitis. I did scrape some of the remaining corneal epithelium from both eyes which was sloughing off to make slides and culture the plates. The Giemsa and gram stain slides revealed plenty neutrophils and some lymphocytes but no organisms were seen. KOH prep was negative. I will inform you of any positive culture growths when the plates are read by our laboratory.

Meanwhile, I have started the patient on Brolene drops 0.1% q 30 mins during the day and q hourly during the night, Norfloxacin eye drops and Torbamycin eys drops q alternate hour in both eyes round the clock and Cyclopentolate 1 % tid. I have also started Ketoconazole 200 mg qd, as we do not have Voriconazole or ltraconazole available here in Moresby. He will be returning back to Sydney on tomorrow (Sunday) afternoon’s flight and has been advised to go straight to the emergency at SHE.

I believe you have a confocal microscope and PCR facility at you institution which may aid in more definitive diagnosis and proper treatment to salvage these eyes.

Thank you for accepting the patient and I look forward to receiving a follow-up on Mr. Lynn.

Regards
