RETINAL BURNS IN PHOTIC RETINOPATHY: THREE CASE REPORTS

Area of Science:

• Ophthalmology
• Retinal Diseases
• Toxicology

Background:

• Photic retinopathy (PR) results from retinal phototoxicity, primarily impacting the macula.
• This condition stems from excessive exposure to intense light sources like the sun, lasers, and welding arcs.
• PR causes oxidative damage to the retinal pigment epithelium (RPE) and photoreceptors, threatening vision.

Purpose of the Study:

• To describe the principal types of retinal burns caused by photic retinopathy.
• To highlight the importance of early recognition and management of PR.
• To emphasize the need for preventing prolonged ocular light exposure.

Main Methods:

• Review and categorization of retinal burn types associated with photic retinopathy.
• Analysis of clinical presentations of solar retinopathy, laser pointer-induced maculopathy, and arc welding maculopathy.
• Discussion of the underlying mechanisms of oxidative damage.

Main Results:

• Identified three primary categories of retinal burns: solar retinopathy, laser pointer-induced maculopathy, and arc welding maculopathy.
• Confirmed that these conditions result from intense light exposure leading to RPE and photoreceptor damage.
• Emphasized the macula as the principal site of injury in PR.

Conclusions:

• Photic retinopathy is a significant cause of vision impairment due to light-induced retinal damage.
• Prompt diagnosis, monitoring lesion progression, and limiting light exposure are essential for managing PR.
• Understanding the distinct mechanisms of solar, laser, and welding-related retinal injuries is critical for prevention and treatment.
