This type of diplopia can arise as a result of: light diffraction, metamorphopsia
, and cerebral polyopia.
It predominantly affects males between 20 to 50 years of age, with dimness of vision, metamorphopsia
and positive scotoma.
, micropsia, central scotoma, or impaired color vision may also occur.
Less common symptoms are metamorphopsia
, floaters and abnormal of colour vision.
Alleye is designed to detect and characterise central and paracentral metamorphopsia
(visual distortions) in risk groups (persons from the age of 55) and in patients with macular conditions including age-related macular degeneration (AMD), diabetic macular edema (DME) and central retinal vein occlusion (CRVO).
Anatomical changes of the fovea induced by VMT can lead to typical symptoms of reduced visual acuity, decreased reading vision, metamorphopsia
, and micropsia.
Visual recovery is generally rapid and of good visual acuity but can leave varying degrees of persistent metamorphopsia
and scotomas .
Tangential tractional force on the retina asserted by an ERM leads to distortion of normal retinal structure and layers, causing symptoms such as impairment of central vision, metamorphopsia
, macropsia, and monocular diplopia [1, 2].
From the history, the approximate distance between the laser device ranged from 0.1 to 2.0 m and symptoms on presentation included decreased visual acuity, central scotomas, and metamorphopsia
Acute CSCR was defined as cases with typical symptoms (decreased vision, metamorphopsia
) for <three months duration and diagnosis confirmed on the basis of clinical examination and OCT/FFA findings by an experienced ophthalmologist.
This semitransparent membrane located between the internal limiting membrane (ILM) and the vitreus causes macular dysfunction, such as macular distortion or edema, leading to a decrease in visual acuity and metamorphopsia
. Retinal surgery releases the tractional forces on the retinal surface.
