Normal Vision Vision with Photopsias
Photopsias are called the "glares or “flashes”" that appear in our visual field, especially in the dark or in low-light conditions. These photopsias are caused by tractions of the vitreous on the retina. Those flashes can disappear or reappear for weeks or months.
Since those same symptoms can hide other more serious conditions, like retinal detachment or tear, it is advisable to visit our ophthalmologist urgently for early diagnosis and possible treatment.

Normal Vision Vision with Metamorphopsia
Metamorphopsia is called the change of the shape of the reflection we're looking at. This condition results in the deformation of our central vision. Reflection deformation, which is usually perceived during reading, is caused by a pathology of the macula. The macula is the central area of the retina, responsible for our clear vision. The ability to recognize objects, e.g. a person's face or the written page, is dependent on its integrity. When the macula malfunctions, the central vision is decreased and often appears deformed (metamorphopsia).
Age-related macular degeneration is probably the most common cause of our patients' central vision deformation. It is usually the wet (exudative) degeneration that indicates fluid accumulation under the macula which is followed by metamorphopsia.
Other disorders that deform central vision are:
Macular hole
Epiretinal membrane
Macular edema (e.g. due to diabetes, or retinal vein occlusion)
Central serous chorioretinopathy.
Normal Vision Vision with Scintillating Scotoma
Some people with migraines (less than one in four) may present “aura”, which sometimes precedes the headaches. Usually, people with migraines falsely call “aura” an indistinct and non specific sense that a migraine crisis is coming. The term “aura”, however, refers to something completely different: “Aura” in migraines is some particular neurological symptoms (of the vision, the senses, movement or speech) that usually precede pain.
The most common aura consists of visual symptoms (visual aura). The person with visual aura might often see bright lines, lights that flicker or blurry segments in his visual field (these symptoms are merely indicative, since there are many types of visual aura). It is usual that the symptoms coexist: a line, bright or not, that may flicker has on one of its sides an area that is not clear (this is called “scintillating scotoma”). The symptoms of visual aura can be found in part of the visual field (right or left), something that makes the person who has them think that they are in one eye (right or left). The visual aura symptoms move within the visual field, more often from the center to the outside. If they can be found in half the visual field, it is often described as “faces and objects seem half”. This lasts less than an hour and often for only 15 or 20 minutes. Migraine headache usually follows the aura, but in some cases it may come before or at the same time.
Besides visual symptoms, some people have sensory aura (“pins and needles”) in one part of the body. Sensory aura usually includes the hand and the head on the same side. Other people experience speech problems as part of their aura (they can't find words or even speak).Even though the aura symptoms can be (at least, initially) scary for some people, they are generally harmless and people with migraines and aura may experience them many times in the course of their lives. However, such symptoms should be reported, in any case, to a neurologist to make sure that they are not caused by something else.
Normal Vision Vision with Glaucoma
Glaucoma is a serious, chronic, progressive disorder of the optic nerve and the nerve fibers of the eye, which leads to morphological damage to the optic nerve and the visual field.
It is an insidious disease, because it has no symptoms (with the exception of some types, like acute glaucoma) and when the first symptoms appear, the damage has advanced and is unfortunately irreversible.
No one should rest easy regarding glaucoma and its consequences. It is very important for all, from children to adults, to examine our eyes thoroughly, because the only way to treat loss of vision and blindness due to glaucoma is to diagnose and treat it early. There are, however, certain conditions linked to the disease, which tend to put the people who have them in higher risk.
Increased intraocular pressure (>21mmHg)) does not necessarily mean glaucoma, just as low intraocular pressure (<21mmHg) does not exclude glaucoma (normal tension glaucoma).

Normal Vision Vision with Daltonism
Daltonism or Color Blindness is the visual disorder in which the patient cannot distinguish certain colors like green and red.
Daltonism is rarely caused by injuries and in these cases it can be treated. In most cases it is inherited and therefore untreatable.
It is not a severe disorder, but it prevents the patient from exercising certain professions, like wherever red and green signals are used (railway driver, sailor, driver etc.) Quite often the person doesn't even know he suffers from daltonism. Diagnosis is done with reams of colored strands or colored tables. Besides the red and green daltonism there is also the cyan eye disorder (acyanopsia).
Depending on the severity degree, there are various abnormalities:
Chromatic abnormalities, protanomaly (red color), deuteranomaly (green color), tritanomaly (cyan)
Dichromacy
Color Blindness, that is total blindness for all colors.
The word daltonism came from Dalton, the English physicist and chemist. He described the disorder, from which he also suffered.
