Ophthalmology lecture

Lecture of the causes of red eyes, Lecture of the causes of blurred vision, Lecture of the vision of the eyes, Pathology of trachoma, Pathology of eye burns, Pathology of eye injuries.

Pathology of corneal ulcers

Superficial keratitis can also be found in acute or chronic diseases of the eyelids and conjunctiva such as tear secretion disorder (dry eye), cleft palate, poisoning.

Pathology of trachoma

Trachoma is a chronic inflammation of the conjunctiva and cornea. The causative agent is Chlamydia Trachomatis, but there are many other microbial agents involved in the disease.

Glaucoma pathology diseases

Glaucoma is one of the leading causes of blindness in our country as well as in the world, if not diagnosed and treated promptly, it can lead to permanent blindness.

Vision and vision examination

Objects viewed to correspond to a certain visual angle at the eye's node, the smallest visual angle that the eye can distinguish between two distinct points.

Pathology of conjunctivitis

Bacterial conjunctivitis can sometimes be severe and affect vision if it is caused by highly toxic bacteria.

Lecture causes red eyes

Treat according to the cause, if possible, it is recommended to do fresh microscopy, direct microscopy, bacterial culture and antibiotic.

Lecture of the cause of blurred vision

An eye examination can reveal a small cornea, a shallow anterior chamber, fundoscopy must adjust the convergence glasses to clearly see the fundus image, the small papillary image can be seen

Eye treatments

Eye treatments: In order to enhance the effectiveness of treatment, in addition to topical application, eye injection methods often have to be combined.

Pathology in children squint (strabismus)

Strabismus measurement involves many steps and is very important because it has a decisive influence on the diagnosis, treatment, and prognosis.

Commonly used eye drops

Disinfectants are nonspecific antibacterial agents with a wide spectrum of action and less local toxicity. In the past, antiseptics were used very widely to treat inflammatory diseases of the eyelids and cornea.

Pathology of uveitis

Uveitis is a fairly common eye disease with a complex aetiology, often severe clinical damage, many complications, or relapses that can lead to blindness.

Eye disease associated with blood disease

For many patients, an eye exam not only allows the detection of eye lesions caused by systemic disease but also helps to confirm diagnosis, prognosis or evaluate the results of systemic treatment.

Cataract pathology

A congenital cataract may be accompanied by strabismus, fibrillation of the eyeball and some manifestations of systemic diseases such as malformations of the skull, skeletal system, intellectual development disorder.

Ophthalmology lecture

When there is circulatory stasis in the venous area, in the head, face, and neck area such as the patient lying on the slope, the carotid vein is squeezed, ocular thrombophlebitis.

Outline of eye anatomy and physiology

The sclera is made up of many layers of thick, crisscrossed tape that are responsible for protecting the membranes and the internal environment.

Injury hit the eyeball

Trauma to the eye can cause dilated pupils or dilated (less common) pupils, and the pupil reflex may become sluggish.

Ocular side effects of some systemic medications

Phenothiazines, Chlorpromazine, and thioridazine can cause visual impairment, deposition in the front of the lens and cornea, altering the retinal pigment epithelium.

Pathology of eye injuries

Swollen and bruised eyelids, difficulty opening eyes, when eyelid hematoma occurs, attention should be paid to the time of appearance, which appears immediately after the impact.

Pathology of eye burns

Eye burns are a special emergency in ophthalmology. In many cases, the damage is very severe, even though urgent treatment does not prevent blindness.

Retinopathy of premature babies

Currently, the understanding of the pathogenesis mechanism as well as the proper regulation of the incubator oxygen level has significantly reduced the incidence of blindness caused by the disease.

Pathology of retinal cancer

If the tumour is large and life-threatening, surgery to remove the eyeball with long nerve vision is needed. The prognosis is good if the tumour has not grown out through the optic nerve.

Eye disease associated with viral disease

The shingles virus (H. zoster) mainly causes disease in the elderly and people with reduced immunity. The first manifestation is mild fever, lymphadenopathy, increasing pain and appearance of blisters on the forehead.

Eye disease associated with neuropathy

Systemic causes can cause pupil reflex disorders. The most common pupil signs are Claude-Bernard-Horner syndrome and Argyll-Robertson pupil.

Eye disease associated with autoimmune disease

Rheumatoid arthritis often causes damage to the tissues containing collagen, especially adrenalitis, scleritis.

Eye disease associated with cardiovascular disease

High blood pressure retinopathy is the most common cardiovascular disease that causes eye damage. Damage to the retina results from hardening of the vascular wall and vasoconstriction.
