Eye infections

Ophthalmology is the area of medicine concerned with diagnosing and treating infections that impact eyes, such as bacteria, viruses or fungi. Eye infections can result from these microorganisms causing symptoms such as pain, blurred vision, itching watery eyes swelling around them thick mucus discharge. Unfortunately these infections are highly contagious spreading from person to person via direct contact.

Pink eye is one of the most common eye infections. It typically affects the clear mucous membrane lining the white part of an eyeball and inner side of eyelid. Pink eye infections typically come from either virus or bacteria infections but could also arise due to environmental or chemical irritants like air pollution or chemicals used for cleaning swimming pools.

Pink eye is an infection of the eyes which typically lasts two to seven days and is highly contagious, spreading via casual contact such as shaking hands, sharing cosmetics or towels or by rubbing or scratching eyes. Left untreated early it can perforate the cornea resulting in permanent loss of vision.

One of the more dangerous eye infections that can cause great discomfort is stye (chalazion). This condition involves pus accumulating in a sac on either lower or upper eyelid, and can be caused by improper contact wearer hygiene, extended wear, sleeping in them overnight, using dirty tissues to wipe the eyes, or by popping or rubbing styes or popping them (rubbing/popping them can lead to orbital cellulitis), and popping one can even worsen matters – leading to infection of orbital cellulitis which requires medical intervention immediately! Stye/chalazion should only be diagnosed by medical professional.

Eye allergies

Eye allergies are an overreaction of the eyes to environmental irritants like pollen, mold spores, dust or pet dander that come into contact with sensitive eye tissue such as cornea and conjunctiva, where allergic responses occur in response to histamine release from immune systems releasing histamine, leading to itchy, watery eyes, redness, swelling or swollen eyelids. They tend to affect more children than adults but individuals born via cesarean are especially prone to develop them.

Eye allergy sufferers frequently exhibit symptoms that include sneezing, runny nose and stuffy head congestion, as well as itchy, swollen or watery eyes. Seasonal allergies can also result in hay fever symptoms; however eye allergies can also be caused by fragrances, smoke, chemicals, food items, insect bites/stings/medication and more.

Eye allergies may manifest themselves through itchy, watery eyes, swollen eyelids and redness or swelling around the eyes. Contact with other substances containing preservatives can also irritate them further, interfering with one’s ability to perform at work or school. Though very common among us all, treating eye allergies with over-the-counter and prescription treatments is available to ease their symptoms.

Avoiding allergens that cause eye allergies is often the most effective form of treatment, including outdoor activities during high pollen seasons, closing windows and using air filters. If avoiding allergens does not work, over-the-counter antihistamine and decongestant eye drops or oral antihistamines/sterroid medications may provide some relief; immunotherapy (allergy shots) may provide longer term solutions – gradually desensitizing your body to them so they no longer cause itchy, watery eyes – eventually eliminating needing allergy drops altogether!

Eye cancer

Cancer of the eye is extremely rare but potentially life-threatening if left undetected for too long. They often start in the skin surrounding or glandular structure within an eyelid gland; however, it can also spread from other parts of the body including breasts, lungs and prostate gland. Some cancers such as melanomas originate within cells producing pigmentation called melanin; these cells then travel via lymphatic system to other parts of the body where lymph nodes transport these cells for distribution to nearby locations.

Factors that increase your chance of eye tumors include age, previous skin cancer history and certain inherited conditions like dysplastic nevus syndrome or BAP1 tumor predisposition syndrome. Other risk factors may include exposure to UV rays, smoking and family history.

Eye cancer often begins as a small nodule or bump on the eyelid that may be painful or itchy, growing over time into something larger and interfering with vision; at times they may even reach deep inside of the eye to affect nerve pathways from retina to brain – the two most frequently found forms being basal cell carcinoma and sebaceous gland carcinoma.

Choroidal melanomas, which start in pigment-producing cells known as melanocytes in the choroid layer of the eye, can affect people of any race or age; though more likely among light-skinned individuals. They often cause blurred vision, retinal detachments, and blindness as potential consequences.

Metastatic melanoma, which spreads from another part of the body via bloodstream to reach eye, is an uncommon but deadly eye cancer that is difficult to treat. Metastatic melanoma often spreads to liver and lungs making it an often deadly disease; early diagnosis allows most patients to be cured; treatment options vary depending on size and stage; they include surgery removal, radiation therapy or laser therapy as treatment methods.

Eye diseases with pictures

Individual’s eyes are their gateway to life; yet according to a recent study, many Americans fail to take eye health seriously enough, even though sight loss can have serious repercussions for everyday living. Luckily, there are ways that can protect vision such as getting regular checkups.

Some common eye diseases, if left untreated, can result in permanent blindness. Examples include age related macular degeneration which blurs an individual’s central vision, and glaucoma which increases eye pressure to damage optic nerves. Both conditions may be prevented or treated depending on their nature and severity.

Other serious eye problems arise due to abnormalities in their structure, such as strabismus. This condition occurs when both eyes don’t line up correctly – this may be congenital but also caused by trauma to the brain or eye disorders such as dry eye syndrome. Strabismus treatments include surgery, patching and glasses.

Retinal Atrophic Maculopathy can also be avoided; this eye disease affects older adults and, left untreated, can result in blindness. Its central portion gradually degenerates, leaving an individual with blurred central vision. Unfortunately, retinal Atrophic Maculopathy often goes undetected, potentially leading to blindness if left untreated.

An eye doctor can aid in the detection and treatment of eye conditions using imaging tools designed for medical diagnostics. Such imaging tools allow the doctor to show a patient how their various structures of the eye work together to form an informed opinion on their eye care plan, before offering advice about preventing or treating any problems they detect, as well as refer patients to specialists if needed. In addition, Baylor University chemistry professor and computer science professor developed a mobile app which scans baby photos for signs of retinoblastoma eye cancer which can potentially lead to blindness – using imaging tools specialized for diagnosis.
