ICD10CM code

#### Name of the Condition
- **Benign Neoplasm of Left Conjunctiva**  
- Technical term: **D31.02**

#### Summary
A benign neoplasm of the left conjunctiva is a non-cancerous growth occurring on the membrane lining the white part of the eye and the inner eyelids. These growths are typically not harmful and do not spread to other parts of the body.

#### Causes
The exact cause of benign neoplasms in the conjunctiva is not fully understood. However, factors such as genetic predisposition or environmental influences like sun exposure may contribute to their development.

#### Risk Factors
- **Age**: More common in aging populations.
- **Sun Exposure**: Chronic UV exposure can increase the risk.
- **Family History**: A history of benign eye growths in the family might elevate risk.

#### Symptoms
- Visible lump or mass on the surface of the eye
- Redness or irritation
- Watery eyes
- Occasionally, a sensation of having something in the eye

#### Diagnosis
- **Physical Examination**: Initial assessment by an eye care professional.
- **Slit-Lamp Exam**: Detailed examination of the conjunctiva.
- **Biopsy**: Rarely, a tissue sample may be needed to confirm the diagnosis.

#### Treatment Options
- **Observation**: Regular monitoring if the growth is small and not causing problems.
- **Surgical Removal**: Necessary if the growth affects vision or causes significant irritation.
- **Cryotherapy**: Freezing technique to remove the growth, used in some cases.

#### Prognosis and Follow-Up
- The condition is generally benign with a good outlook after treatment.
- Regular eye examinations are important to monitor for changes in the growth.

#### Complications
- Transformation to a malignant form is rare.
- Possible irritation or discomfort if left untreated.

#### Lifestyle & Prevention
- **Shield Eyes from UV Light**: Wearing sunglasses can help reduce risk.
- Regular eye check-ups to catch any growths early.

#### When to Seek Professional Help
- Sudden changes in size, shape, or symptoms of the growth.
- Persistent irritation or vision changes.
