Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Increased Intraocular Pressure
Elevated pressure inside the eye that can damage the optic nerve and lead to glaucoma.
Seek immediate medical attention if experiencing severe eye pain, vision loss, or seeing halos around lights.
Sudden Vision Loss
Rapid loss of vision function that may occur due to severe structural abnormalities or complications.
This is a medical emergency. Seek immediate emergency care if experiencing sudden vision loss.
Blurred Vision
(ophthalmologic)Vision becomes unclear or fuzzy due to structural abnormalities in the cornea, lens, or iris affecting light refraction.
Frequency: 70-80% of patients
Photophobia
(ophthalmologic)Increased sensitivity to light causing discomfort or pain when exposed to bright light sources.
Frequency: 60-70% of patients
Corneal Opacity
(ophthalmologic)Clouding or scarring of the clear front window of the eye, affecting vision clarity.
Frequency: 40-50% of patients
Iris Abnormality
(ophthalmologic)Structural defects in the colored part of the eye, including missing segments or irregular pupil shape.
Frequency: 35-45% of patients
Eye Pain
(ophthalmologic)Discomfort or aching sensation in or around the eye, often associated with structural abnormalities or pressure changes.
Frequency: 10-15% of patients
Diplopia
(ophthalmologic)Double vision occurring when abnormal eye structure affects proper visual alignment.
Frequency: 8-12% of patients
Headache
(neurologic)Persistent headache often associated with eye strain from visual abnormalities or increased intraocular pressure.
Frequency: 15-20% of patients
Nausea with Vomiting
(gastrointestinal)Feeling sick to the stomach with vomiting, which may occur with acute angle-closure or severe eye pressure.
Frequency: 2-5% of patients
