What are the symptoms and treatment options for retinal issues?

Symptoms and Treatment Options for Retinal Issues

The most common retinal issues include posterior vitreous detachment (PVD), retinal breaks, and retinal detachment, which require prompt evaluation by an ophthalmologist to prevent vision loss and preserve quality of life. 1

Common Symptoms of Retinal Issues

• Flashes (photopsias) - Light flashes that are most noticeable in dark environments, caused by vitreous traction on the retina during PVD 1
• Floaters (myodesopias) - May be due to blood from torn retinal vessels, condensations of vitreous collagen, or epipapillary glial tissue 1
• Peripheral visual field loss - May indicate progression to retinal detachment 2
• Blurred vision - Common with more advanced retinal issues 2
• Distorted vision (metamorphopsia) - Particularly common in macular disorders like age-related macular degeneration 3
• Central vision loss - Occurs in advanced cases, especially with macular involvement 3

Diagnostic Approach

• Dilated fundoscopic examination is essential for all patients with acute onset of flashes or floaters to detect retinal breaks 1, 4
• Examination of peripheral fundus using scleral depression is crucial to detect retinal breaks that may lead to detachment 1, 5
• B-scan ultrasonography should be performed when media opacity prevents adequate examination 5
• Optical coherence tomography is indicated if vitreomacular traction is present 1
• Wide-field photography may be helpful but does not replace careful ophthalmoscopy 1

Treatment Options Based on Condition

1. Posterior Vitreous Detachment (PVD)

• Observation is appropriate for uncomplicated PVD without retinal breaks 1
• Follow-up examination within 6 weeks is recommended for patients with acute PVD, particularly those with vitreous pigment, hemorrhage, or visible vitreoretinal traction 1
• Pars plana vitrectomy may be considered if symptomatic floaters remain bothersome after several months 1, 5

2. Retinal Breaks and Tears

• Laser photocoagulation or cryotherapy should be applied promptly to symptomatic retinal tears to create a chorioretinal adhesion and prevent progression to retinal detachment 1
• Treatment should extend to the ora serrata for horseshoe tears if they cannot be completely surrounded 1
• Prompt treatment reduces the risk of retinal detachment from over 50% to less than 5% for symptomatic tears 1

3. Retinal Detachment

• Immediate referral to an ophthalmologist is required for suspected retinal detachment 1, 2
• Surgical intervention is necessary for nearly all symptomatic rhegmatogenous retinal detachments (RRD) 1
• Early diagnosis and treatment are crucial as more than 95% of uncomplicated RRDs can be successfully repaired, with better visual outcomes when repaired before macular involvement 1

Special Considerations

• Risk factors for retinal detachment include advancing age, previous cataract surgery, myopia, and trauma 2
• Patients with lattice degeneration require regular follow-up visits, especially younger myopic patients with holes 1
• Pseudophakic patients are more likely to require retreatment or develop new breaks 1
• 10-16% of patients will develop additional breaks during long-term follow-up 1

Follow-up Recommendations

• Patients with no positive findings at initial examination should follow standard comprehensive eye evaluation schedules 1
• Treated patients should be seen at 1-2 weeks post-treatment, then at 2-6 weeks to assess the adequacy of the chorioretinal scar 1
• All patients with risk factors should be advised to contact their ophthalmologist promptly if new symptoms develop 1

Warning Signs Requiring Immediate Attention

• Sudden increase in floaters or flashes 4
• Curtain-like shadow in peripheral vision 6
• Rapid deterioration of vision 1
• New onset of distorted vision 3

Remember that early intervention facilitates prevention of retinal detachment and improves visual outcomes of retinal detachment surgery 2.
