Aqueous cells without the signs of uveitis, elevated intraocular pressure and rhegmatogenous retinal detachment with tears around the ora serrata are the main signs of Schwartz–Matsuo syndrome. [1] Intra ocular pressure can be as high as 60–70 mm Hg and is responsive to aqueous suppressants. [ 3 ]
During rhegmatogenous retinal detachment, fluid from the vitreous humor enters a retinal hole. The mechanisms by which retinal holes or tears form are not fully understood yet. The accumulation of fluid in the subretinal space and the tractional force of the vitreous on the retina result in rhegmatogenous retinal detachment.
Retinal detachment is a condition where the retina pulls away from the tissue underneath it. [1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4] Retinal detachment is a medical emergency that requires surgery. [2] [3]
Vitreomacular traction syndrome (VTS) is a medical condition in the eye that is the result of tractional forces (pulling) being placed on the retina. [1] [2] VTS is common in people who have an incomplete posterior vitreous detachment, a type of retinal detachment at the periphery of the retina. [1]
[18] [19] This has allowed OCTA to obtain detailed images of retinal vasculature in the human retina [20] and become widely used clinically to diagnose a variety of eye diseases, such as age related macular degeneration (AMD), [21] diabetic retinopathy (DR), [22] [23] artery and vein occlusions, and glaucoma. [24] [18]
Ocular OCT retinal thickness map, right eye Time-domain OCT of the macular area of a retina at 800 nm, axial resolution 3 μm Spectral-domain OCT macula cross-section scan. Optical coherence tomography (OCT) is a technique for obtaining sub-surface images of translucent or opaque materials at a resolution equivalent to a low-power microscope.
Those areas infected by cytomegalovirus have cells evolve to necrosis, though inflammation within the retina is not great. Rhegmatogenous retinal detachments can occur following the development of holes in areas of healed retinitis (retina may be atrophic). [11] [12] Proliferative vitreoretinopathy has been observed in cases of retinal ...
These two images are later used together to create a 3D image. In this way the image can be analysed giving better information about surface characteristics of the retina. [19] Fundus photography in animals: Fundus photography is a useful tool utilised for veterinary research, veterinary ophthalmology, as well as education. [20]
