![]() The explanation of some of the causes is below All these things can lead to Neurological Problems. Some of the other reasons for this disorder may include Neuropathic Disorders, Trauma, Medications, Drugs, Poisoning and injury on Spinal Cord. ![]() The opposite of dilated Pupil is known as Miosis. The main reason seen behind the constant dilated Pupil is the release of Oxytocin. There are different causes which can lead to the dilated Pupil, these causes include natural, un-natural both.įollowing are the causes of dilated PupilĪttraction may fall under the category of natural causes of dilated Pupils.ĭilated Pupils Ecstasy is also a cause of overexcitement that an individual may experience while having a strong Libido. It enables an individual to see the objects even in the dim light. Pupils dilate to allow the more light to enter the Eyes. The dilated Pupil is caused due to the Stimulus to Light where the Pupils narrow when the Light brightens and dilates when the light gets dim. Life threatening cases of dilation can show serious problems like Coma, Muscle weakness and Shocks. Severe cases of dilated Pupil can cause inability to control the Bowel’s and Bladder, Numbness and Paralysis. This disorder is related to the Neurological problems so it can cause These symptoms are accompanied with the symptoms linked with the other symptoms of other factors that cause it. The symptoms of the dilated Pupils depend on the hidden causes of this disease. This condition is known as Unilateral Dilation of the Pupils. Patients may also suffer from 1 dilated Pupil. Image by : wikimedia Unilateral Dilation of Pupil Once these are systematically excluded, benign episodic unilateral mydriasis should be considered a possibility.Possible physical effects of lysergic acid diethylamide 1 Adies pupil and trauma are other common causes. These pupils can be identified by their refusal to constrict with 1% Pilocarpine. 4 Pharmacological blockade is the most common cause of such a presentation. 1 We found only one report of an intracranial aneurysm causing internal ophthalmoplegia without extraocular muscle involvement. 3 In the absence of any other ocular abnormality, unilateral mydriasis is rarely due to an intracranial cause. A systematic approach is required to examine and investigate this condition. The cataracts in our patient were an incidental finding.Īnisocoria is often viewed as a worrying sign. 2 The dilated pupil is the only ocular finding. 2 The episodes may be accompanied by blurred vision, orbital pain, headache, or photosensitivity. The features of our patient were consistent with a rare but innocuous condition termed ‘benign episodic unilateral mydriasis.’ 2 The affected individuals, usually women, often have a history of migraine. Each time there were no other significant findings and pharmacological tests were negative. Three of these episodes were accompanied by headache and two by ocular pain. Over the next 2 years, this patient presented four times with similar episodes of unilateral mydriasis, twice affecting the left eye ( Figure 1b). The anisocoria spontaneously disappeared in 3 days. It was observed that 0.125% Pilocarpine did not constrict the pupil, whereas 1% Pilocarpine constricted both pupils well. There was no other ocular abnormality, except for the previously noted cataracts. There was no ptosis and full ocular motility. Her vision was unchanged from her last visit to the department. A detailed history revealed no trauma and no possibility of pharmacological dilation. Six months later, she was referred to us with a dilated left pupil. This was interpreted as an abnormally prolonged response to tropicamide drops. The right pupil, however, remained dilated ( Figure 1a). The abrasion healed in 2 days with vision improving to 6/18. Examination revealed bilateral congenital cataracts. Vision was 6/12 in the right eye and 6/36 in the left. She was systemically well, except the occasional classical migraine. A 39-year-old lady presented to the casualty with a traumatic corneal abrasion to the left eye.
