Rhegmatogenous retinal detachment is caused by a tear or break in the retina. [6] [9] This allows vitreous humor, the fluid that normally sits in the center of the eye, to build up behind the retina. [6] [9] As a result, the retina can eventually separate from the tissues underneath it. [6] [9] [10] This is the most common type of retinal ...
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.
Rhegmatogenous retinal detachment, when the retina breaks allowing vitreous fluid to leak into the subretinal space, resulting from intravitreal injection is rare, occurring at most in 0.67% of people. [6] This fluid can cause sensory tissues to detach from the retina, thus losing their source of nutrition, and slowly killing the cells. [8]
Rheumatism [2] / ˈ r uː m ə t ɪ z əm / or rheumatic disorders are conditions causing chronic, often intermittent pain affecting the joints or connective tissue. [3] Rheumatism does not designate any specific disorder, but covers at least 200 different conditions, including arthritis and "non-articular rheumatism", also known as "regional pain syndrome" or "soft tissue rheumatism".
Retinal tufts can classified into three subtypes: cystic, non-cystic, and zonular traction retinal tufts. [5] Cystic tufts are usually larger than 0.1mm in length. [5] Non-cystic retinal tufts are usually shorter, less than 0.1mm in length and are often clustered together in a series of projections within the vitreous base. [5]
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 detachment.
Intravitreal injection was first mentioned in a study in 1911, in which the injection of air was used to repair a detached retina. [6] [7] [8] There were also investigations evaluating intravitreal antibiotics injection using sulfanilamide and penicillin to treat endophthalmitis in the 1940s, yet due to the inconsistency of results and safety concerns, this form of drug delivery was only for ...
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 ...
