Graves' ophthalmopathy, also known as thyroid eye disease (TED), is an autoimmune inflammatory disorder of the orbit and periorbital tissues, characterized by upper eyelid retraction, lid lag, swelling, redness , conjunctivitis, and bulging eyes (exophthalmos). [1]
Diplopia (double vision) is common. [4] Limitation of eye movement (due to impairment of eye muscle function). Periorbital and conjunctival edema (accumulation of fluid beneath the skin around the eyes). In severe cases, the optic nerve may be compressed and acuity of vision impaired. [24] Occasionally loss of vision.
Micropsia is a condition affecting human visual perception in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema, macular degeneration, or central serous ...
Blurred vision: Those with nonexudative (dry) macular degeneration may be asymptomatic or notice a gradual loss of central vision, whereas those with exudative (wet) macular degeneration often notice a rapid onset of vision loss (often caused by leakage and bleeding of abnormal blood vessels).

Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception.In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking.

Peripheral (posterior) vitreous detachment occurs when the gel around the eye separates from the retina. This can naturally occur with age. However, if it occurs too rapidly, it can cause photopsia which manifests in flashes and floaters in the vision. Typically, the flashes and floaters go away in a few months.
Symptoms include blurred vision, loss of vision, and photopsia, but there may be no symptoms. [4] Tumors arise from the pigment cells that reside within the uvea and give color to the eye. These melanocytes are distinct from the retinal pigment epithelium cells underlying the retina that do not form melanomas. When eye melanoma is spread to ...
Keratoconus (KC) is a disorder of the eye that results in progressive thinning of the cornea. [3] This may result in blurry vision, double vision, nearsightedness, irregular astigmatism, [4] and light sensitivity leading to poor quality-of-life.
