Photostress recovery time measurement procedure is known as photostress test. Normal recovery time is about 15–30 seconds. [1] The photostress test is a simple, easy and quick clinical technique that can differentiate between retinal and postretinal (e.g.optic nerve) disease. [2]
Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes.Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).
Macular pucker: Macular pucker also known as an epiretinal membrane cause metamorphopsia and distortions in central field of vision. Cystoid macular edema: Due to macular edema, micropsia may occur. [3] Glaucoma: Amsler grid is useful in detecting central field defects in moderate to severe glaucoma. [7]

They may also have eye pain or headaches. Vision impairment is usually in both eyes, but can be in just one. Impairment of a person with 20/20 vision usually ends up being about 20/40 ...

They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
Recovery of visual acuity usually follows. Treatment should be considered if resorption does not occur within 3–4 months, [ 19 ] spontaneously or as the result of counselling.

The sign test is a statistical test for consistent differences between pairs of observations, such as the weight of subjects before and after treatment. Given pairs of observations (such as weight pre- and post-treatment) for each subject, the sign test determines if one member of the pair (such as pre-treatment) tends to be greater than (or less than) the other member of the pair (such as ...
