centre are a very important part of our body and essential for our right functioning . It is only through them that we can see and perceive the world and live a meaningful life . Without our sense of construe , we are nothing . The disease of the eye affects its normal functions and cook our life unmanageable . Hence , we require to be watchful about the dissimilar eye diseases and take good care of them . Among the various heart disease , occurrence of Pigment dissemination syndrome ( PDS ) , which is an eye disorder , is very rare .
What is Pigment Dispersion Syndrome?
The colour of the middle is due to the presence of a paint in the sword lily . In case of Pigment diffusion syndrome , this paint is exhaust from iris and it swim in the sedimentary humour and clogs the trabecular mesh . This prevent the flow of aqueous humor and construct pressure inside the optic which affects the ocular nerve leading to pain in center and blurring of vision .
Signs and Symptoms of Pigment Dispersion Syndrome
The early stages of Pigment dispersion syndrome are asymptomatic ; therefore it is unmanageable to get it on if the person is affected . Later there is personnel casualty of peripheral vision and in in advance stages there is loss of central sight . During these stages :
Signs of Pigment Dispersion Syndrome
Epidemiology of Pigment Dispersion Syndrome
The incidence of pigment dispersion syndrome is thought to be 4.8 per 100,000 of the universe . It has increased incidence in the Caucasian universe . Mostly men are affect , but it is also observed in women . The onslaught of pigment dispersion syndrome is between 20 - 40 years . Most of these patients havemyopiaor near sighted . A distinctive pigment dispersion syndrome patient is a young white nearsighted male . It is bilateral and there is no typical hereditary pattern noticed . Most of the case are sporadic . It is an autosomal prevailing upset with genic mark establish on chromosome 7q35 - 36 .
Prognosis of Pigment Dispersion Syndrome
If untreated , pigment dissemination syndrome may leave in Pigmentary Glaucoma which leads to blindness . If diagnosed in early stages then controlling pigment dispersion syndrome is much better than in later phase .
Causes of Pigment Dispersion Syndrome
paint dispersion syndrome is a rare condition . Hence , the exact cause for this disease is still unknown . Most of the typesetter’s case are sporadic and the genetic linkage or inheritance shape has not yet been clearly show .
One of the possible cause due to which pigment dispersion syndrome develops is that some people have alone build of optic which cause the lens zonule ( fibres ) to scratch against the back of the iris . This releases the pigment from iris which lead to pigment diffusion syndrome . It has been hypothecate that athlete who play basketball or are in excessive physical activity have an increased incidence of paint dispersion syndrome .
Pathophysiology of Pigment Dispersion Syndrome
Pigment dispersion solvent due to handout of paint from the iris which floats to the aqueous humour . Over the prison term , with child amounts of this pigment gather in different parts of the prior chamber such as corneal endothelium , iris surface , trabecular meshwork ( TM ) , lens surface and zonula . Aqueous fluid which is unceasingly produced by the optic normally flows out of the eye through its drain system called trabecular meshwork . The pigment congest the ok trabecular meshwork and forbid the draining of aqueous humour . This leads to increase in intraocular pressure and starts regard the optic nerve fibres . When the pressure is high-pitched enough to damage theoptic nerveit is name as pigmentary glaucoma . In the long term , this conduct to irreversible loss of the vision .
Risk Factors of Pigment Dispersion Syndrome
Some of the hazard factors for paint diffusion syndrome are :
Complications of Pigment Dispersion Syndrome
paint diffusion syndrome is not fatal . However , when the pressure inside the eye continue to increase , it starts affecting the optic nerve which leads to a experimental condition called pigmentary glaucoma . The pigmentaryglaucomathen progresses to irreversible loss of vision . The probability of rebirth of pigment diffusion syndrome to pigmentary glaucoma is 10 % in 5 year and 15 % in 15 year .
Diagnosis of Pigment Dispersion Syndrome
Diagnosis of paint dispersion syndrome is done by the eye doctor and optometrist in two to three visits . They examine the eyes , cornea and iris . They perform visual testing and measurements of ocular field and eye insistency .
Treatment of Pigment Dispersion Syndrome
The proper management of pigment dispersion syndrome is done as conform to :
Prevention of Pigment Dispersion Syndrome
Pigment dispersion syndrome is a rarefied disorder of the eye . If diagnosed ahead of time , then to some extent , it is treatable . With further research about its pathophysiology and with improved discussion modalities , the affected role with pigment dispersion syndrome will have good caliber of life .
