Thank you for the information,
The dilation of pupil in dark or dimmer light is a normal phenomenon and is controlled by the brain. The pupil also constricts when you come in the bright sunlight.We are usually unware of this phenomenon.You should not worry about this.
The dilatation may also occur at the time of anxiety, fear, emotions, certain drugs,brain tumour etc. apart from being in darkness.
You should have the urine c/s and urine routine examination done to know the associated abnormality after consulting your doctor.The commonly prescribed antibiotics are ciprofloxacin, ofloxacin, nitrofurantoin, etc.for 5-7 days duration.
You may take the cranberry juice and a lot of vitamin c to treat the uti in a natural way.The drinking of a lot of water also helps in the symptoms and flushes the bacteria out.The antifungal may be needed in rare cases of suspected fungal infection.
