Patients can experience solar retinopathy after viewing the eclipse without protection, but it also can occur from outdoor activities, including those mentioned. It can lead to symptoms that include blurry vision, vision loss at the center of a patient’s sight, and eye pain.
Waiting for the condition to pass may be one course of management for patients with solar retinopathy. You may also schedule follow-up examinations to monitor patients with symptoms, and educating patients that using protective eyewear is the best way to void this form of vision loss is key.
According to a study,1 eclipse viewing is the leading cause of solar retinopathy. Victims of solar retinopathy may complain of blurred vision, a central black spot, and metamorphopsia.
“After 6 months the visual acuity is usually in the range of 6/5 to 6/12 but frequently with a small central subjective scotoma,’ researchers said in a study. “Visual acuity does not always recover and has reportedly remained as low as 3/60 with permanent retinal damage in the form of retinal holes and pseudoholes.”
After a week the initial deep yellow exudate shrinks and may be surrounded by a red halo followed by retinal pigment epithelium hypopigmentation with surrounding pigment clumping at 6 weeks. The appearance of a lamellar macular hole at or adjacent to the foveal reflex may develop.2
Solar retinopathy occurs as a result of exposure to direct sunlight, and the most common cause is viewing a solar eclipse.
While some patients may see their symptoms clear up in weeks or months, other patients do not fully recover their sight after solar retinopathy. Patients may require the following:
- Optical coherence tomography to examine the surface of the retina;
- Slit lamp examination to view the patient’s retina;
- Photographs of the retina to monitor changes;
- Fluorescein dye tests to monitor blood vessels
The foveal cones can prove to be resilient and resist damage from the sun’s rays and resist photochemical damage. This is why patients may see symptoms ease over time.
Suffering solar retinopathy can lead to permanent damage, and patients may experience low vision, and, prevention may be the best approach, including:
