Metamorphopsia is a upset of the optic which is characterized by the twisting in the visual sensation of the eye . In this condition , a storage-battery grid constituting square line appear wavelike to the observer ; in some cases , some parts of the grid may seem vacuous as well . Metamorphopsia is commonly observed in individuals suffering from macular disorders .
What is Metamorphopsia?
When individual are ineffectual to perceive the optic image distinctly , unremarkably accompany by color shape and size of the object , then such a condition is prognosticate Metamorphopsia . The peripheral limits of the eye which are responsible for the characterization ofhallucinationsget affected in Metamorphopsia . The intellectual cortex gets pissed due to two kinds of problems in the eye which are refractile errors and pathological alterations of the retinal setup within the eye .
The retinal errors fall out when the light get in the eye is not able to directly focus on the retina . In showcase of Metamorphopsia , the amount of optical power require to watch a clean image is not at par with the distance of the optic from the aim , resulting in distorted ikon . The distorted shape of vision can be either macropsia or micropsia . In eccentric of macropsia , the pattern of the object in imaginativeness is likely colour , whereas in case of micropsia , the size of the object which is perceived is not correct , it can come along either large or smaller .
In typeface of pathological change happening in the retinal receptor apparatus , the visual nerve ending present at the retina get inflamed and sometimes may also get scarred , resulting into ill-shapen imaginativeness .
Causes of Metamorphopsia
The causative factors behind Metamorphopsia are :
Symptoms of Metamorphopsia
The characteristic symptom that identify Metamorphopsia are :
Pathophysiology of Metamorphopsia
The main cause behind the occurrence of Metamorphopsia is the alteration in the photoreceptor levels , due to the inspissation of the inner nuclear stratum and the layer of ganglionic cells . This further mar the right functioning of the synaptic junctions , thus lead to decreased sensitivity of the photoreceptors contribute to Metamorphopsia .
Risk Factors of Metamorphopsia
The unwashed risk factor that pose a threat for Metamorphopsia are :
Treatment of Metamorphopsia
The discussion for Metamorphopsia focuses on treating the causative factor behind the condition . The treatment is done as survey :
Diagnosis of Metamorphopsia
The identification of Metamorphopsia can be done through few tests :
Metamorphopsia is a stipulation which produces wrong vision which is characterized by the appearance of wavy and buxom lines along with blanks when viewing matted surfaces . The stipulation is normally an result of prevailing ailment like hemicrania , macular fix and degeneration and retinal detachment . The experimental condition can be efficiently diagnosed using ophthalmological analysis and Amsler ’s tests . The treatment for Metamorphopsia aim at treating the underlying causative constituent . However , if not cover on time , it can lead to imaginativeness deprivation .
