Acute zonal occult outer retinopathy (AZOOR) is an inflammatory retinopathy in the category of white dot syndromes typified by acute loss of one or more zones of outer retinal function associated with photopsia, minimal funduscopic changes and abnormal electroretinography findings.
Gass described the 'AZOOR complex' which consists of multiple evanescent white dot syndrome, nultifocal choroiditis, punctate inner choroiditis, acute idiopathic blind spot enlargement, acute macular neuroretinopathy, acute annular outer retinopathy, and acute zonal occult outer retinopathy. He suggested these diseases represent one disease due ...
Autoimmune retinopathies such as cancer associated retinopathy (CAR), melanoma associated retinopathy (MAR), and acute zonal occult outer retinopathy (AZOOR) Retinal detachment; Assessment of retinal function after trauma, especially in vitreous hemorrhage, dense cataracts, and other conditions where the fundus cannot be visualized.
Photopsia; This is an approximation of the zig-zag visual of a scintillating scotoma as a migraine aura. It moves and vibrates, expanding and slowly fading away over the course of about 20 minutes.
The Marcus Gunn pupil is a relative afferent pupillary defect indicating a decreased pupillary response to light in the affected eye. [3]In the swinging flashlight test, a light is alternately shone into the left and right eyes.
Recently, central serous chorioretinopathy has been understood to be part of the pachychoroid spectrum. [5] [6] In pachychoroid spectrum disorders, of which CSR represents stage II, the choroid, the highly vascularized layer below the retina, is thickened and congested with increased blood vessel diameter, especially in the deep choroid (the so-called Haller's layer).
Many ophthalmic imaging techniques are used in detecting hypotony maculopathy. Indocyanine green angiography or fluorescein angiography can help in early detection of choroidal disturbances and choroidal folds.
Aniseikonia is an ocular condition where there is a significant difference in the perceived size of images. It can occur as an overall difference between the two eyes, or as a difference in a particular meridian. [1]
