H33.323 Round hole, bilateral

ICD10CM code

#### Name of the Condition
- Common Name: Bilateral Round Hole
- Technical Term: H33.323

#### Summary
- Bilateral round hole is a condition characterized by the presence of round-shaped holes in the retinas of both eyes, often leading to impaired vision. These holes can cause symptoms such as floaters or flashes and may require medical attention to prevent further complications.

#### Causes
- The condition is often caused by degenerative changes within the vitreous humor of the eye, leading to pulling or thinning of the retina.

#### Risk Factors
- Age (more common in older adults)
- Family history of retinal problems
- Previous eye injuries or surgeries
- Myopia (nearsightedness)

#### Symptoms
- Presence of floaters or flashes of light
- Blurred vision
- Peripheral vision loss
- Visual distortions

#### Diagnosis
- Comprehensive eye examination
- Ophthalmoscopy to view the retina
- Optical coherence tomography (OCT) for detailed imaging
- Fluorescein angiography to assess retinal circulation

#### Treatment Options
- Observation for minor cases with regular monitoring
- Laser photocoagulation to seal the holes and prevent retinal detachment
- Cryotherapy as an alternative treatment to laser photocoagulation
- Vitrectomy surgery in advanced or complicated cases

#### Prognosis and Follow-Up
- With timely treatment, the prognosis is generally good, and vision can stabilize.
- Regular follow-up is crucial to monitor the condition and prevent complications such as retinal detachment.

#### Complications
- Untreated round holes can lead to retinal detachment, which can cause permanent vision loss without prompt surgical intervention.

#### Lifestyle & Prevention
- Regular eye examinations, especially for high-risk individuals
- Protective eyewear in high-risk activities to prevent trauma
- Control of underlying health conditions like diabetes or hypertension

#### When to Seek Professional Help
- Sudden increase in floaters or flashes
- Sudden loss of vision or the appearance of a shadow or curtain over part of the visual field

#### Additional Resources
- American Optometric Association (AOA)
- American Academy of Ophthalmology (AAO)
- Retina patient support groups for peer support and information

#### Tips for Medical Coders
- Ensure bilateral specification is clear for accurate coding (ICD-10 code H33.323).
- Double-check the documentation to confirm the presence of unilateral vs. bilateral condition.
- Consider coding any adjunctive treatments or related procedures separately.
