Cataracts, high myopia, and floaters?

Following up on question 198091, I feel that my vision is slightly dim in both eyes when looking individually.
Should I go to the hospital for further examination? What specific conditions would warrant a hospital visit? During my dilated eye exam on June 12, the doctor mentioned that my vision was acceptable, so I don't think surgery is necessary; I was advised to have regular check-ups instead.
Currently, I do not feel that my vision is blurry.
Could the dimming of my peripheral vision potentially indicate other symptoms?

Hello: Darkening of the visual field can be a symptom of various eye or systemic conditions.
Here are some possible situations that may lead to darkening of the visual field:
1.
Glaucoma: Glaucoma is an eye disease characterized by increased intraocular pressure that damages the optic nerve.
This can lead to a constricted visual field and a sensation of darkening.
2.
Cataracts: Cataracts refer to the clouding of the eye's lens.
If cataracts are severe, they may affect the passage of light through the lens into the eye, resulting in a darkened visual field.
3.
Macular degeneration: The macula is the area located at the back of the retina responsible for central vision.
Macular degeneration (such as age-related macular degeneration) can cause blurriness or weakening of central vision, often accompanied by a sensation of darkening in the visual field.
4.
Abnormal intraocular pressure: In addition to glaucoma, other abnormalities in intraocular pressure, whether too high or too low, can also lead to a sensation of darkening in the visual field.
5.
Retinal detachment: Retinal detachment refers to the separation of the retina from the inner layer of the eyeball.
This can lead to vision loss or darkening of the visual field.
Additionally, some systemic diseases and medication side effects may also cause darkening of the visual field, such as diabetes, hypertension, stroke, and drug toxicity.
These are just some possible causes; a specific diagnosis requires a detailed evaluation and examination by a physician.
If the physician has checked and found no issues, other conditions may have been ruled out.
It could be caused by cataracts.
However, if you are concerned, it is perfectly fine to get another check-up.

More Info

When it comes to changes in vision, particularly symptoms like darkening of the visual field or experiencing visual disturbances, it is essential to approach the situation with caution. Your description of perceiving a slight darkening in your visual field when viewing with each eye separately is noteworthy and warrants further attention.
Firstly, it is important to understand that any noticeable change in vision, even if it seems minor, should not be overlooked. Vision changes can be indicative of various underlying conditions, some of which may require prompt medical intervention. For instance, symptoms such as sudden vision loss, persistent visual disturbances (like flashes of light or floaters), or any significant changes in how you perceive light should prompt an immediate visit to an eye care professional.

In your case, since you mentioned that you have undergone a dilated eye exam (散瞳檢查) and your doctor indicated that your vision is still acceptable, it is reassuring. However, the fact that you are experiencing a darkening of the visual field could suggest a few possibilities. This symptom could be related to age-related changes in the eye, such as cataracts or retinal issues, or it could be associated with other systemic conditions that affect vision, such as hypertension or diabetes.

It is also worth noting that visual field changes can sometimes precede more serious conditions, such as glaucoma or retinal detachment. These conditions can lead to irreversible vision loss if not treated in a timely manner. Therefore, if you notice any additional symptoms, such as increased frequency of darkening, flashes of light, or if the darkening becomes more pronounced, it is crucial to seek further evaluation from an eye care specialist.

Regular check-ups are essential, especially if you have a history of eye issues or if you are at risk for conditions that can affect your vision. Your doctor’s recommendation for periodic examinations is wise, as it allows for monitoring of any changes over time. If you feel that your symptoms are worsening or if new symptoms arise, do not hesitate to reach out to your healthcare provider for further assessment.

In summary, while your current situation may not seem alarming, it is always better to err on the side of caution when it comes to eye health. If you experience any new or worsening symptoms, or if the darkening of your visual field persists, you should definitely seek further evaluation. Early detection and intervention can make a significant difference in preserving your vision and overall eye health.
