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]
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 ]
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.
Proliferative vitreoretinopathy (PVR) is a disease that develops as a complication of rhegmatogenous retinal detachment.PVR occurs in about 8–10% of patients undergoing primary retinal detachment surgery and prevents the successful surgical repair of rhegmatogenous retinal detachment.
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]
The Heidelberg Retinal Tomography is a diagnostic procedure used in ophthalmology.The Heidelberg Retina Tomograph (HRT) is an ophthalmological confocal point scanning laser ophthalmoscope [1] for examining the cornea and certain areas of the retina using different diagnostic modules (HRT retina, HRT cornea, HRT glaucoma).
[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.

The visual pathway consists of structures that carry visual information from the retina to the brain.Lesions in that pathway cause a variety of visual field defects. In the visual system of human eye, the visual information processed by retinal photoreceptor cells travel in the following way:
