ICD-10: H31.113

Age-related choroidal atrophy, bilateral, is classified under the ICD-10 code H31.113. This condition is characterized by the progressive degeneration of the choroidal layer of the eye, which is essential for providing nutrients and oxygen to the outer retina. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description

Definition

Age-related choroidal atrophy refers to the thinning or loss of the choroidal tissue, which can occur as part of the aging process. This atrophy can lead to various visual disturbances due to its impact on the retinal pigment epithelium and photoreceptors.

Etiology

The exact cause of age-related choroidal atrophy is not fully understood, but it is believed to be associated with several factors, including:
- Aging: Natural degeneration of ocular tissues over time.
- Genetic predisposition: Family history may play a role in susceptibility.
- Environmental factors: Exposure to UV light, smoking, and diet may contribute to the risk.

Symptoms

Patients with bilateral age-related choroidal atrophy may experience:
- Visual disturbances: Such as blurred vision or difficulty seeing in low light.
- Scotomas: Areas of partial or complete loss of vision in the visual field.
- Decreased contrast sensitivity: Difficulty distinguishing between similar shades.

Diagnosis

Diagnosis typically involves:
- Comprehensive eye examination: Including visual acuity tests and dilated fundus examination.
- Imaging studies: Such as optical coherence tomography (OCT) and fluorescein angiography, which can help visualize the extent of choroidal atrophy and assess retinal health.

Differential Diagnosis

It is important to differentiate age-related choroidal atrophy from other retinal conditions, such as:
- Age-related macular degeneration (AMD): A more common condition that affects the macula and can lead to severe vision loss.
- Choroidal neovascularization: Abnormal blood vessel growth that can occur in various retinal diseases.

Management and Treatment

Currently, there is no specific treatment for age-related choroidal atrophy. Management focuses on:

Clinical Presentation

Overview

Age-related choroidal atrophy typically manifests in older adults, often as part of a broader spectrum of age-related macular degeneration (AMD). The bilateral nature of this condition indicates that both eyes are affected, which can lead to symmetrical visual changes.

Signs and Symptoms

Patients with bilateral age-related choroidal atrophy may present with a variety of signs and symptoms, including:

• Visual Disturbances: Patients often report gradual vision loss, particularly in central vision, which can affect activities such as reading and recognizing faces. This is due to the atrophy affecting the macula, the central part of the retina responsible for sharp vision[1].

• Scotomas: The presence of scotomas, or blind spots in the visual field, is common. These can be central or peripheral, depending on the extent of the atrophy[1].

• Difficulty with Low Light: Patients may experience increased difficulty seeing in low-light conditions, a condition known as night blindness, due to the compromised function of the retinal cells[1].

• Distorted Vision: Some patients may report metamorphopsia, where straight lines appear wavy or distorted, which can be particularly distressing[1].

Patient Characteristics

The demographic profile of patients with age-related choroidal atrophy typically includes:

• Age: Most commonly affects individuals aged 50 and older, with prevalence increasing significantly in those over 70 years[1][2].

• Gender: There may be a slight female predominance, although both genders are affected[2].

• Risk Factors:

• Genetic Predisposition: Family history of AMD or other retinal diseases can increase risk.
• Environmental Factors: Prolonged exposure to UV light, smoking, and poor diet (low in antioxidants) are associated with higher incidence rates[2].
• Comorbidities: Conditions such as hypertension, diabetes, and cardiovascular diseases may also contribute to the risk of developing choroidal atrophy[2].

Conclusion

Age-related choroidal atrophy, particularly in its bilateral form, presents a significant challenge for affected individuals, primarily due to its impact on vision. Understanding the clinical presentation, signs, symptoms, and patient characteristics is crucial for early diagnosis and management. Regular eye examinations and monitoring for those at risk can help in managing the condition and potentially slowing its progression. If you suspect you or someone you know may be experiencing symptoms related to this condition, consulting an ophthalmologist is essential for appropriate evaluation and intervention.
