Loss of visual acuity or sharpness of vision can have serious repercussions for daily activities, affecting ones ability to complete them efficiently and safely. Although some cases of this condition are irreversible, in other cases improvement can be achieved with regular screening and discontinuing medications as well as nutritional supplement use. It may also be beneficial to seek medical advice.

A 67-year-old female with systemic lupus erythematous on therapeutic doses of Plaquenil for 30 years developed progressive macular damage over time. Fundus photos revealed depigmented areas on either side of her fovea bilaterally consistent with bull’s eye maculopathy.

Risk factors

Age-related macular degeneration (AMD) is a progressive condition that deteriorates the clear, central vision that’s necessary for everyday tasks like driving and reading, leading to blindness among people over 50 and impacting over 10 million Americans. Early-on AMD may not cause noticeable symptoms; as the disease advances it may result in vision loss in one or both eyes; further symptoms may include wavy or blurred vision, difficulty reading, color changes and missing spots or shadows near the center of your vision.

Plaquenil macular toxicity risk can be minimized by closely managing and overseeing its use, such as scheduling regular eye exams, taking only what is prescribed, screening for other risk factors like preexisting retinal disease and renal or liver dysfunction, using lower dosage, discontinuing it immediately if symptoms arise, and discontinuing altogether if damage becomes permanent – however this cannot always be reversed by discontinuing medications like Plaquenil altogether.

Wet AMD occurs when abnormal blood vessels form below the macula and bleed or leak, leading to swelling of the retina and eventually vision loss. Although less common than dry AMD, its impact can be more serious; available treatments for wet macular degeneration include nutritional supplements that contain antioxidant vitamins such as lutein and zeaxanthin, as well as new types of therapy known as anti-angiogenic drugs injected directly into eye to prevent formation of new vessels that damage macula.

Risk factors associated with wet macular degeneration increase with age, family history, smoking, high cholesterol levels and obesity; it’s more prevalent among Caucasians and females. Diagnosing AMD can be difficult; early symptoms often have no noticeable manifestations; but viewing an Amsler grid test can help identify whether there are symptoms present that indicate AMD.

Symptoms

Macular degeneration is a disease that primarily impacts the central portion of your visual field, often leading to blurry or distorted vision and eventually leading to blindness. It is caused by damage to the macula, which sends signals from the retina to your brain about color and detail perception. Aging is generally the leading cause, while smoking, high blood pressure, lighter eye color, farsightedness or diet low in vitamins may increase risk factors and hasten this process further.

Macular degeneration typically manifests with distortion or missing parts of straight objects in your central vision and a dark spot near its center, as well as difficulty with activities like driving or reading. Macular degeneration typically progresses slowly over time and may go undetected until being seen by an eye doctor for another reason – though even then many do not recognize they are losing central vision until seeing an ophthalmologist for another purpose.

Hydroxychloroquine (plaquenil) can occasionally cause retinal toxicity by damaging cells that detect light and transmit visual signals to your brain. Unfortunately, its side effects often remain undetected until significant vision loss has taken place; symptoms include changes in color vision, shadowed or missing spots in central vision, distortion or blurriness of straight lines as well as distortion or blurriness in certain lines.

Diagnoses of plaquenil retinal toxicity typically take the form of eye exams conducted by your physician, including an extensive history review, slit lamp examination of both eyes, vision testing, and any special tests of the retina such as fluorescein angiography.

When detected early, discontinuing hydroxychloroquine can help stop further retinal damage and in some cases allow for recovery of visual function. Other treatments for macular degeneration include visual aids and nutritional supplements like lutein and zeaxanthin that support retinal health; new anti-angiogenic drugs have also been developed specifically to slow progression; they target and destroy abnormally leaking blood vessels associated with wet macular degeneration.

Diagnosis

Macular degeneration’s symptoms include reduced visual acuity and blurred or distorted central vision, which may impact your ability to see fine details or complete daily tasks. Left untreated, macular degeneration could eventually lead to severe vision loss or blindness.

Age-related macular degeneration (AMD), which affects the retina of the eye, is a prevalent and serious condition among older people, which often leads to blindness. AMD typically arises from blood vessel breakdown at the back of the eye which then allows fluid or blood leakage into the macula from newly formed vessels, eventually blurring or disappearing altogether while other parts of retina called peripheral retina continue to function normally allowing you to retain side (peripheral) vision such as seeing clock numbers and hands when viewing an angle etc.

Macular degeneration comes in two varieties, dry and wet. Dry macular degeneration is the more prevalent form, often manifesting as gradual vision loss in its wake. Wet AMD differs by producing new blood vessels beneath the retina known as choroidal neovascularization (CNV), which leak fluid and blood, blurring or distorting central vision and can quickly result in rapid vision loss. Wet AMD should always be taken more seriously than dry AMD as rapid vision loss may occur from it.

If you have wet macular degeneration, your doctor may suggest laser treatment to slow or stop the development of abnormal blood vessels. This treatment involves painlessly targeting an area on the retina where these abnormal vessels have sprouted to provide targeted laser light treatment that targets these abnormal vessels for destruction – though this won’t restore vision that has already been lost from wet macular degeneration.

Anti-angiogenesis agents such as bevacizumab, ranibizumab and pegaptanib can be administered intraocularly to combat the proliferative growth of new blood vessels that contribute to wet macular degeneration. They should be given every four weeks in order to combat it more effectively and slow its progress for some patients.

Treatment

Plaquenil toxicity treatment depends on how much retinal tissue has been affected by it, with various symptoms including blurred vision, changes in color perception and loss of central vision as a possible side effect. If left untreated, plaquenil poisoning could even lead to permanent blindness.

Although its exact mechanism remains elusive, we know that medication accumulates in the retina over time and damages cells that detect light and transmit visual signals to the brain. Retinal pigment epithelium (RPE) cells are especially sensitive to medication accumulation, with increased amounts causing these cells to degenerate leading to macular toxicity and possibly macular degeneration.

However, early stage patients may not show any symptoms, which makes regular eye exams imperative to monitoring the condition. Exam frequency will depend on each individual patient’s risk factors and needs; it is recommended that a baseline exam be scheduled within 6-12 months of beginning Plaquenil therapy in order to detect potential issues prior to their occurrence and provide opportunities for early intervention.

Whenever symptoms of macular toxicity appear, patients should immediately discontinue use of any drug that might contribute to them. Doing so will help stop further progression and damage to retinal tissue; an ophthalmologist can evaluate and prescribe appropriate therapies.

An ophthalmologist may prescribe nutritional supplements or injections to restore vision. These may include vitamins C and E, lutein and zeaxanthin; these nutrients have been suggested to counteract plaquenil’s harmful effects while improving RPE cell health. In combination with other treatments (e.g. anti-VEGF therapy), such as anti-VEGF therapy can also be effective against macular degeneration progression.
