Retinal Lattice Degeneration: Key Facts and Treatment Options
Lattice degeneration is a significant yet often overlooked condition affecting the retina. This degenerative disorder can lead to retinal tears or detachment if left untreated. Know the symptoms, risk factors, diagnosis and treatment options for lattice degeneration, as well as its potential connection to retinal tears.
What is Lattice Degeneration?
Lattice degeneration refers to a condition where the peripheral retina becomes thinned and develops a lattice-like pattern of crisscrossing white lines. These lines are often accompanied by pigmentary changes and small round holes. The condition is usually bilateral, meaning it affects both eyes, and is more prevalent in individuals with myopia (nearsightedness).

Lattice degeneration often presents without symptoms, making it difficult to diagnose without an eye examination. However, some individuals might experience:
- Flashes of light (photopsia)
- Floaters (small moving spots in the field of vision)
- Sudden loss of vision or shadow over the visual field (indicative of a retinal tear or detachment)
Causes of Lattice Degeneration
The exact cause of lattice degeneration remains unclear, but several factors contribute to its development:
- Genetic predisposition: A family history of lattice degeneration or retinal detachment increases the risk.
- Myopia: Individuals with higher degrees of nearsightedness are more susceptible.
- Age: The condition is more commonly diagnosed in individuals aged 20-40.
- Trauma: Previous eye injuries can exacerbate the thinning of the retina.
Lattice Degeneration Risk Factors
Understanding the risk factors associated with lattice degeneration is crucial for early diagnosis and intervention. Key risk factors include:
- Genetics: A family history of retinal disorders can increase susceptibility.
- Nearsightedness (Myopia): Individuals with high myopia are at a higher risk.
- Age: Younger adults, particularly those in their 20s and 30s, are more likely to develop lattice degeneration.
- Previous eye trauma: Injuries to the eye can contribute to retinal thinning and lattice formation.
Diagnosis of Lattice Degeneration
A comprehensive eye examination is essential for diagnosing lattice degeneration. The following diagnostic tools and procedures are commonly used:
- Dilated Fundus Examination: An ophthalmologist will use special drops to dilate the pupils and examine the retina using a slit lamp.
- Ocular Coherence Tomography (OCT): This imaging technique provides detailed cross-sectional images of the retina, allowing for the identification of thinning and lattice patterns.
- Fluorescein Angiography: A dye is injected into the bloodstream to highlight blood vessels in the retina, aiding in the detection of abnormal retinal conditions.
Treatment for Lattice Degeneration
Observation and Regular Monitoring
In many cases, lattice degeneration does not require immediate treatment but necessitates regular monitoring. Patients are advised to undergo routine eye examinations to detect any changes in the retina that might indicate progression toward retinal tears or detachment.
Laser Photocoagulation
Laser photocoagulation is a common preventive treatment for lattice degeneration. This procedure involves the use of laser energy to create small burns around the lattice areas, which helps to seal any potential retinal tears and reduce the risk of detachment. The laser burns create a scar that acts as a barrier, preventing further progression of the degeneration.
Cryotherapy
Cryotherapy involves the application of extreme cold to the lattice areas, creating a similar effect to laser photocoagulation. This procedure also aims to reinforce the retina and prevent the development of retinal tears or detachment.
Surgical Intervention
In severe cases where retinal tears or detachment occur, surgical intervention may be necessary. Procedures such as scleral buckling or vitrectomy are performed to reattach the retina and prevent further vision loss.

Lattice degeneration is strongly associated with an increased risk of retinal tears and detachment. The thinning of the retina in lattice degeneration makes it more vulnerable to tears, especially in areas of lattice formation. Early detection and treatment of lattice degeneration are critical in preventing these severe complications.
Preventive Measures and Lifestyle Modifications
While lattice degeneration cannot be entirely prevented, certain measures can reduce the risk of progression and complications:
- Regular Eye Examinations: Routine eye check-ups are essential for early detection and monitoring of lattice degeneration.
- Protective Eyewear: Wearing protective eyewear during activities that pose a risk of eye injury can help prevent trauma-related retinal damage.
- Managing Myopia: Controlling nearsightedness through corrective lenses or refractive surgery can reduce the risk of lattice degeneration.
- Healthy Lifestyle: Maintaining a healthy lifestyle, including a balanced diet rich in antioxidants, can support overall eye health.
Frequently Asked Questions
1. What causes lattice degeneration of the retina?
Lattice degeneration is caused by thinning and atrophy of the peripheral retina, which can increase the risk of retinal tears.
2. What are the symptoms of lattice degeneration?
Symptoms are often absent but can include flashes of light or floaters in the vision.
3. How is lattice degeneration diagnosed?
Diagnosis is made through a comprehensive eye exam and retinal imaging.
4. What treatments are available for lattice degeneration?
Treatment may include laser therapy to seal weak areas and prevent retinal detachment.
5. Can lattice degeneration lead to blindness?
While lattice degeneration can increase the risk of retinal detachment, early intervention can prevent vision loss.
