Conjunctival Stones: Causes, Symptoms, and Treatment Options - Ophthalmology

More Info

---

Understanding conjunctival stones, also known as "concretions," is essential for anyone experiencing symptoms related to eye discomfort or visual disturbances. Conjunctival stones are small, yellowish-white deposits that can form on the conjunctiva, the clear membrane covering the white part of the eye and the inner eyelids. They are typically composed of calcium and other mineral deposits and can occur due to various factors, including chronic irritation, inflammation, or dryness of the eyes.


Causes of Conjunctival Stones
1. Chronic Irritation: Frequent exposure to irritants, such as smoke, dust, or oil fumes, can lead to inflammation and the formation of conjunctival stones. In your case, working in a kitchen may expose your eyes to oil and other irritants, which could contribute to the development of these deposits.

2. Dry Eyes: Insufficient tear production can lead to dryness, which may cause irritation and the formation of conjunctival stones. Wearing contact lenses, especially for extended periods, can exacerbate this condition.

3. Age: As people age, the likelihood of developing conjunctival stones increases due to changes in the conjunctiva and tear film.

4. Underlying Conditions: Certain medical conditions, such as chronic conjunctivitis or blepharitis, can predispose individuals to develop conjunctival stones.


Symptoms
While conjunctival stones can be asymptomatic, they may cause the following issues:
- Blurred vision, particularly if the stones are large or located in a position that interferes with the visual axis.

- Mild irritation or discomfort, although significant pain or redness is uncommon.

- Increased tearing or discharge from the eye.


Treatment Options
1. Observation: If the conjunctival stones are small and not causing significant discomfort or visual disturbances, observation may be sufficient. Your doctor has indicated that surgery is not necessary at this time, which is a common approach for asymptomatic cases.

2. Medications: The use of lubricating eye drops, such as artificial tears, can help alleviate dryness and irritation. If your doctor has prescribed eye drops, continue using them as directed. You may also inquire about using artificial tears to help with dryness, especially if you are concerned about your eyes becoming dry from reduced contact lens wear.

3. Surgical Removal: If the stones become symptomatic or interfere with vision, surgical removal may be considered. However, this is typically reserved for cases where the stones cause significant discomfort or visual impairment.


Addressing Your Concerns
1. Difference in Eye Prescription: It is possible that if you are straining your right eye more due to the left eye's blurriness, it could lead to changes in the prescription over time. However, this is not a guaranteed outcome. Regular eye examinations can help monitor any changes in your vision.

2. Need for Surgery: Based on your doctor's assessment, if the conjunctival stones are not causing significant discomfort or visual impairment, surgery may not be necessary. It is essential to follow up with your eye care provider to monitor the condition.

3. Additional Eye Drops: You can use artificial tears to help with dryness, but it is advisable to consult your eye doctor before adding any new medications to ensure they are appropriate for your situation.


Conclusion
In summary, conjunctival stones are generally benign and can often be managed with observation and symptomatic treatment. It is crucial to maintain regular follow-ups with your eye care provider to monitor your condition and address any changes in your vision or discomfort. If you experience any worsening symptoms, such as increased pain, redness, or significant changes in vision, seek medical attention promptly. Taking care of your eye health, especially while wearing contact lenses, is vital to prevent further complications.
