<unk> s are extremely painful due to nerve exposure, and can cause tearing, squinting, and vision loss of the eye. There may also be signs of anterior uveitis, such as miosis (small pupil), aqueous flare (protein in the aqueous humour), and redness of the eye. An axon reflex may be responsible for uveitis formation—stimulation of pain receptors in the<unk> results in release inflammatory mediators such as prostaglandins, histamine, and acetylcholine. Sensitivity to light (photophobia) is also a common symptom of<unk> . Redness of the affected eye is common. Brow ache and head ache may be present. Drooping of eye lid may be present. Slit lamp examination shows loss of epithelium. The site of the<unk>  is studied and marked in case sheet. The edge of the<unk>  is studied. Whether satellite lesion is present or not is seen. Next, the<unk> is stained with 1% fluorescein. The<unk>  is stained green.
