Illusory palinopsia is often worse with high stimulus intensity and contrast ratio in a dark adapted state.Multiple types of illusory palinopsia often co-exist in a patient and occur with other diffuse, persistent illusory symptoms such as halos around objects, dysmetropsia (micropsia, macropsia, pelopsia, or teleopsia), Alice in Wonderland Syndrome, visual snow, and oscillopsia.
Conjunctival concretions can be seen easily by everting the eyelid. The projecting concretions can be removed if they are causing concerning symptoms. Removal can be performed by an eye doctor. Sometimes just a needle or a scalpel is used to remove the concretion under local light anesthesia of the conjunctiva in adults.

If the patient's eyelids feel stuck to the cornea on waking and no intense pain is present, use a fingertip to press firmly on the eyelid to push the eye's natural lubricants onto the affected area. This procedure frees the eyelid from the cornea and prevents tearing of the cornea. [5]
Entoptic images have a physical basis in the image cast upon the retina. Hence, they are different from optical illusions, which are caused by the visual system and characterized by a visual percept that (loosely said) appears to differ from reality.
Artificial tear eye-drops or ointments may be a suitable treatment for mild cases. Low-dosage steroidal eye-drops, such as prednisone, fluorometholone, loteprednol (Lotemax 0.5%) or rimexolone. Steroidal drops should be used with caution [5] and the eye pressure should be regularly checked during treatment. Soft contact lenses.
[1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4] Retinal detachment is a medical emergency that requires surgery. [2] [3] The retina is a thin layer at the back of the eye that processes visual information and sends it to the ...
The cornea is a clear part of the eye which controls and focuses the entry of light into the eye. Damage to the cornea due to corneal perforation can cause decreased visual acuity. Damage to the cornea due to corneal perforation can cause decreased visual acuity.
