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
