macular pucker

macular pucker

A wrinkling and eventual scarring of the retina in the macular area, resulting in visual distortion.
Synonym: premacular fibrosis; cellophane maculopathy

fibrosis, preretinal macular

Proliferation of glial cells over the surface of the internal limiting membrane of the macular region of the retina. Ophthalmoscopically the retina presents a glinting reflex. The condition may occur after trauma, eye surgery, retinal vascular disease (e.g. branch retinal vein occlusion) and inflammation and with any of the causes of retinitis proliferans and most commonly in elderly patients. Initially the patient is asymptomatic or reports some distortion of vision (metamorphopsia). This stage is often called cellophane maculopathy. As the condition develops, visual acuity diminishes, there is retinal wrinkling and the preretinal membrane becomes denser obscuring some retinal vessels in ophthalmoscopy. Some patients may also develop a macular hole and posterior vitreous detachment. If vision is significantly reduced, the main treatment is by vitreous surgery with removal of the layer of preretinal proliferative tissue. Syn. epiretinal membrane; macular epiretinal membrane; macular pucker; premacular fibrosis; preretinal membrane; preretinal vitreous membrane; surface wrinkling retinopathy. See proliferative retinopathy.

The multicolour image is made up of three reflectance images which can be viewed separately to enable the ophthalmologist to study the details of different layers of the retina and detect pathologies associated with the structures irrespective of each other.16 Muftuoglu et al, in his study of visualization of macular pucker by multicolour imaging, showed that 56.2% ERM was better visualized by using multicolour imaging than CFP.17 Similar results, in favor of multicolour OCT in detection of ERM was also demonstrated by L Reznicek et al.18 Similarly, a study was conducted by Ben Moussa N et al, which stated that multicolour OCT have proved to be an excellent tool for measurement of geographic atrophy.19
Some examples are: macular degeneration; diabetic eye disease; retinal detachment; retinoblastoma; macular pucker; macular hole; and floaters (https:// medlineplus.gov/retinaldisorders.html).
(13) used preoperative slit-lamp biomicroscopy, B-scan USG, and OCT to evaluate the presence of PVD in 30 eyes scheduled for vitrectomy due to MH or macular pucker. They reported that slit-lamp biomicroscopy and USG provided more accurate diagnostic results based on intraoperative findings.

As the membrane thickens and contracts it creates retinal folds and is known as 'macular pucker'.
Maculopathy (macular scar, macular pucker), corneal decompensation, corneal opacity and raised intraocular pressure were the major complications associated with compromised visual outcome.
Complication of Laser Photocoagulation (11, 12, 13) These include accidental foveal burns, macular edema and macular pucker, pre-retinal fibrosis, hemorrhage from retina and choroid, tractional retinal detachment, retinal hole formation, ischaemic papillitis.
Other applications of OCT in ophthalmology include retinal pigment epithelial detachment, epiretinal membranes (ERM)/ Macular pucker (cellophane maculopathy), vitreomacular traction, rhegmatogenous retinal detachment, macular pseudoholes, lamellar holes, full thickness holes, retinoschisis, age related macular degeneration, choroidal neovascular membranes, retinal angiomatosis, and disciform scars / subretinal fibrosis, etc.
"Macular pucker, or wrinkling of the macula, is an entirely different problem in which thin membrane-like scar tissue forms on the macula and distorts it, leading to blurred and sometimes wavy central vision.
