In May, Lily’s left eye and then her right eye appeared bloodshot. At first I put it down to the use of sunscreen. The strong summer sun means the girls and I were slapping on sun protection every time we go out walking, swimming or are doing outdoor chores. But when I thought about it, I realised that the redness in Lily’s eyes was not the same as that caused by sunscreen. For one, the sunscreen causes a general redness, like you get after swimming in a chlorinated swimming pool. Lily’s eyes had triangular redness starting at a point at her tear duct near her nose and fanning out to her iris. Lily, being at an age when she is conscious of her appearance, asked me frequently about this redness and when it would go away.
Her left eye gradually cleared of any redness, but then she developed it in her right eye. Then one day, seeing her in a different light, I noticed bumps on the edge of her iris, where the redness ended. There were two of these little bumps, and they looked liked blisters. She didn’t complain of any pain, but said her eyes often felt dry. I took her to the doctor the next day.
The doctor immediately diagnosed pterygium, also known as ‘surfer’s eye’. The redness was the immediately recognisable first symptom of tissue growth on the surface of the eyeball. The bumps on the edge of the iris are lesions and the growth and lesions may continue to grow until they eventually cover the pupil, leading to blurred vision, astigmatism and corneal scarring. It can affect one or both eyes. Laser surgery and replacement of eye tissue with amniotic membrane are two treatments, although these treatments are only necessary if vision becomes affected.
The cause is simple – excessive exposure to sun, wind and sand. Well, living the lifestyle we do, on a boat, in countries at lower latitudes, spending lots of time on beaches, my children are prime candidates for such eye damage. The problem is most common among people who live closer to the equator and among men aged 20 to 40 (because they are the ones who spend more time out of doors).
Our mission now is to prevent Lily’s pterygium from getting worse. The doctor prescribed the use of artificial tears (eye drops) and the wearing of sunglasses and a sunhat when outside. After using the eye drops for a couple of days the redness had disappeared and the doctor advised using the eye drops whenever the redness recurs. Julian, down in Vila Real a couple of days later, bought both girls good quality polarising sunglasses that provide both UVA and UVB protection. Now we insist they both wear sunglasses and sunhats when out during the day. Although Lily was quite upset by it all at first, she has grown used to wearing her sunglasses now, especially because Dad bought her such cool ones!
I wanted to share this as a word of warning. No matter where you live, but particularly if you live in a part of the world that gets prolonged and strong sunlight, protect your eyes and the eyes of your loved ones. Lily’s eye damage is the latest in a line of northern Europeans living here on the river dealing with the consequences of sun damage. Pre-cancerous moles and melanomas seem to be on the rise these days amongst our friends.
Also, a word of warning about the type of sunglasses you buy. Dark lenses don’t necessarily mean sun protection. Make sure your glasses and your kids’ glasses provide UVA and UVB protection. Dark lenses dilate the pupil and allow more light in, and without ultraviolet protection this leads to even greater sun damage. And, if like me, you wear glasses for short sightedness, pay that extra £10 on your new prescription for the ultraviolet filter.
We will continue to enjoy living in such a sun-kissed part of the world, but from now on we will do so with greater care, not just for our skin, but for our eyes too.
