The commonest causes of pain in the temple area with affected vision in the same side eye are -
- glaucoma - raised intraocular pressure of the eye
- uveitis - inflammation in the eye
- rarely migraine headache
- other problems can be a foreign body in the eye, dryness etc
Chlorsig is an ointment used for bacterial conjunctivitis or infection of the eye. Since you have no discharge in the affected eye, it would not be of much help. I would recommend you to consult an Ophthalmologist for a first hand evaluation as soon as possible to diagnose the exact cause and start treatment.
