Also, I did come across a research paper that said the constricting effect of Pilocarpine is proportional to its strength, and did try diluting mine without much success - but that was a very amateur attempt involving salt water, so maybe that's why it didn't work. So to my question: are there other pupil-constricting drugs out there I could try? A glaucoma website I visited lists quite a few drugs with a pupil-constricting effect, but I'm not sure if people without glaucoma can take them. Sure enough, I looked up Alphagan, and found that asthmatics shouldn't take it, as it increases attacks. Unfortunately, I'm an asthmatic, and suddenly noticed I was having far more attacks. And so I asked my general doc to try me on Alphagan, and this has been much more successful: it constricts the pupil just enough to take away the glare, and its effects last longer. Also, I've read that if you use them for long enough, the pupil constriction is permanent, making eye examinations and other surgical procedures difficult (the surgeon never told me THAT). His solution was to prescribe Pilocarpine eye drops to constrict the pupils, and although they were very effective, they had three disadvantages: (1) they gave me 'brow ache', (2) the effect wasn't long-lasting and worst of all, (3) they contricted my pupil way down to pinhead size, meaning that my night vision was almost gone. But despite this, I've suffered terribly from glare and halos, and despite what the surgeon said, I haven't neuroadapted at all. At these moments when your pet is ill or maybe needs surgery, you want to be protected for the unexpected and high veterinarian costs.Last May I had cataract surgery on both eyes, and in order to minimise the possibility of complications, I chose single-vision IOLs (Tecnis silicone). During its lifetime your pet is exposed to many illnesses and diseases and some breeds are affected by a congenital disease which is a condition existing at birth. When adding a dog or cat to your family you want to make sure your pet is happy, healthy and protected. Your veterinarian will use an Ultrasound to search for any possible trauma and an MRI or CT scan to look for a growth that could be the cause of the constriction. Causes of Constriction Of The PupilĬonstriction of the pupil may be due to inflammation, increased pressure or built up scar tissue in the eye, cancer or a tumor, or an eye disease. If one or both pupils appear smaller than usual or do not dilate in the light, it can be a sign of an underlying issue. It is advised to consult a veterinarian in case of constriction of the eye to determine the cause. Issues with the eye can have a great impact on your pet's vision, which is why you should never wait with taking action. If your dog or cat has a reduced size of the eye pupil, or constriction of the pupil, it's possible it can be caused by a trauma to the eye or a systematic disease.
