Pachychoroid disorders of the macula represent a group of diseases affecting the central part of the retina of the eye, the macula. Due to thickening and congestion of the highly vascularized layer underneath the macula, the choroid, damage to the retinal pigment epithelium and the retinal photoreceptor cells ensues. This leads to impaired vision.
Other names: Inherited retinal dystrophy/diseases: Back of the eye of a person with mid-stage retinitis pigmentosa. Note pigment deposits in the mid periphery along with retinal atrophy. While the macula is preserved there is some loss of pigmentation around it. Specialty: Ophthalmology, Optometry: Symptoms
Retinal detachment: Detachment of retinal pigment epithelium (H35.8) Other specified retinal disorders (H35.81) Macular edema — distorted central vision, due to a swollen macula (H35.9) Retinal disorder, unspecified [1]

It is described as an exudative maculopathy, characterised by multiple recurrent serosanguineous retinal pigment epithelial detachments. [3] Elevated reddish to orange lesions on fundus examination, dilated inner choroidal vessels, and polypoidal vascular structures beneath the retinal detachment are other features of PCV. [4]
This is a shortened version of the sixth chapter of the ICD-9: Diseases of the Nervous System and Sense Organs.It covers ICD codes 320 to 389.The full chapter can be found on pages 215 to 258 of Volume 1, which contains all (sub)categories of the ICD-9.
The pathogenesis of cone dystrophy has yet to be elucidated. It appears that the dystrophy is primary, since subjective and objective abnormalities of cone function are found before ophthalmoscopic changes can be seen. However, the retinal pigment epithelium (RPE) rapidly becomes involved, leading to a retinal dystrophy primarily involving the ...
An Amsler grid, as it might be viewed by a person with very severe macular pucker.Most cases of epiretinal membrane are milder and show much smoother curved lines. The source of the cells in epiretinal membranes (ERM) has been found to comprise glial cells, retinal pigment epithelial (RPE) cells, macrophages, fibrocytes, and collagen cells.
