What happens during the disease - glaucoma, unspecified
Существует несколько теорий глаукомного повреждения:
- Механическая теория — глаукомное повреждение возникает из-за прямой компрессии (сдавлении) зрительного нерва в отверстиях решётчатой пластинки диска.
- Ишемическая теория — повышенное внутриглазное давление негативно сказывается на кровоснабжении зрительного нерва.
- Дисрегуляторная теория — нарушение саморегуляции сосудистого тонуса независимо от внутриглазного давления приводит к патологическим изменениям зрительного нерва и сетчатки.
Также имеется некая схожесть патогенеза первичной открытоугольной глаукомы и нейродегенеративных заболеваний, связанных с возрастом (болезнью Альцгеймера, болезнью Пика и др.).
В случае закрытоугольных форм глаукомы механизм развития заключается в нарушении оттока жидкости в глазу вследствие полного либо частичного закрытия радужкой угла оттока. Невозможность оттока жидкости приводит к быстрому (в течение нескольких часов) и сильному (более 40 мм рт. ст.) повышению внутриглазного давления, что делает клиническую картину более яркой.
Clinical Pattern
How does a doctor diagnose
- Comprehensive eye exam
- Tonometry to measure the pressure in the eyes
- Gonioscopy to examine the drainage angle of the eyes
- Ophthalmoscopy to examine the optic nerve
- Visual field testing to measure peripheral vision
- Optical coherence tomography (OCT) to measure the thickness of the optic nerve
- Pachymetry to measure the thickness of the cornea
Treatment and Medical Assistance
- Prescribe medications to reduce intraocular pressure
- Administer laser therapy to reduce intraocular pressure
- Perform surgery to reduce intraocular pressure
- Instruct patient on lifestyle modifications to reduce intraocular pressure
- Monitor patient's vision and intraocular pressure regularly
- Provide patient with educational materials on glaucoma
- Refer patient to a specialist for further evaluation and treatment

Main symptoms of the disease glaucoma, unspecified
Decreased vision
(Impaired vision, Blurred vision, Diminished vision, Reduced vision, Fuzzy vision, Clouded vision, Hazy vision, Poor vision, Weak vision, Low vision)
Decreased vision is a symptom of many underlying conditions. It can range from mild blurring of vision to complete loss of sight. It can develop gradually or suddenly, and may be accompanied by pain, headaches, or double vision. Depending on the underlying cause, it can be partial or complete, affec...
Photophobia
(Light sensitivity, Light intolerance, Light aversion, Light sensitivity disorder, Light-sensitive eyes, Sunlight sensitivity, Intolerance to light, Intolerance to bright light, Discomfort with bright light, Avoidance of light)
Photophobia is an extreme sensitivity to light. Symptoms include squinting, eye pain, and headaches. It can develop due to a variety of causes, including physical and mental health conditions, medications, and eye injuries. It can manifest as an aversion to bright light, or a feeling of discomfort a...
Lacrimation
(Watering eyes, Tearing eyes, Teary eyes, Excessive tearing, Eye watering, Crying eyes, Shedding tears, Lachrymation, Overflowing tears, Watery eyes)
Lacrimation is the excessive production of tears, either from the eyes or from the nose. It can be caused by a variety of conditions, such as allergies, infections, or irritants. Symptoms typically start with stinging, burning, and itching of the eyes, followed by excessive tearing. Redness and swel...
Increasing the size of the eyeball
(Enlarged eyeball, Bulging eyeball, Dilated eyeball, Swollen eyeball, Inflamed eyeball, Extended eyeball, Protruding eyeball, Puffy eyeball, Distended eyeball, Expanded eyeball)
The symptom of an enlarged eyeball, also known as proptosis, is characterized by the eyeball protruding out of its socket. It usually develops gradually and can be accompanied by redness, swelling, and pain. It can be caused by a variety of conditions, including inflammation, infection, trauma, and ...
Corneal edema
(Corneal swelling, Corneal oedema, Swollen cornea, Corneal waterlogging, Corneal clouding, Corneal engorgement, Corneal congestion, Corneal infiltration)
Corneal edema is a condition in which the cornea of the eye becomes swollen or cloudy due to the accumulation of fluid. It can be caused by trauma, infection, inflammation, or other eye diseases. Symptoms may include pain, blurred vision, sensitivity to light, and redness. In more severe cases, the ...
Decreased pupillary light reflex
(Diminished pupillary reflex, Impaired pupillary reflex, Abnormal pupillary reflex, Reduced pupillary reflex, Weak pupillary reflex, Slowed pupillary reflex, Blunted pupillary reflex, Lowered pupillary reflex, Lessened pupillary reflex, Subdued pupill...)
Decreased pupillary light reflex is a medical symptom characterized by reduced pupil constriction when exposed to light. It typically starts with a decrease in the size of the pupil when exposed to light, followed by a slower-than-normal return to its original size. It may also be accompanied by a d...
Eye inflammation
(Eye irritation, Red eyes, Swollen eyes, Itchy eyes, Teary eyes, Watery eyes, Sore eyes, Grainy eyes, Burning eyes, Dry eyes, Painful eyes, Inflammation of the eyes)
Eye inflammation is an inflammation or infection of the eye, which can cause redness, itching, swelling, pain, and discharge. It can develop over time due to allergies, bacterial or viral infections, or environmental irritants. Symptoms can range from mild to severe and may include blurry vision, ex...
Nausea
(Upset stomach, Queasiness, Queasy feeling, Stomach discomfort, Gastric unease, Stomach churning, Stomach upset, Stomachache, Feeling sick, Feeling queasy, Stomach queasiness, Feeling nauseous, Feeling nauseated, Nauseousness)
Nausea is an unpleasant feeling in the upper abdomen that may be accompanied by an urge to vomit. It can range from mild to severe and can be accompanied by symptoms such as sweating, dizziness, and increased salivation. Nausea can be caused by a variety of stimuli, including motion sickness, certai...

Matte white or gray rings around the edge of the cornea, known as Vogt's limbal girdle, is a symptom of corneal degeneration. It appears as a series of concentric circles around the outer edge of the cornea and can be associated with a decrease in vision. It can occur as a result of aging, inflammat...
