“…This situation is called blue light hazard. Acute damage to the retina by accidentally gazing at sun light, arc welding light, laser light from medical and industrial equipment, and light emission diodes used in toys has been reported [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. However, the harmfulness of chronic exposure to blue light of certain wavelengths is still controversial [23][24][25][26].…”

Purpose We previously reported that macular pigment optical density (MPOD) levels decreased during a long follow-up period after clear intraocular lens (IOL) implant surgery presumably due to excessive light exposure. We examined changes in MPOD levels in the eyes that received yellow-tinted IOL implant surgery. Subjects and methods This was a prospective, observational study. Fifty-five eyes of 35 patients were studied. MPOD levels were measured with a dual-wavelength autofluorescence technique on day 4; months 1, 3, and 6; and years 1 and 2 postoperatively. The average optical densities at 0°- 2° eccentricities (local MPODs) and total volumes of MPOD (MPOVs) in the area within 1.5° and 9° eccentricities were analyzed. Results The mean local MPOD at baseline (on day 4) was 0.79 at 0°, 0.71 at 0.5°, 0.68 at 0.9°, and 0.32 at 2°. The mean MPOV within 1.5° and 9° at baseline was 2950 and 18,897, respectively. Local MPOD at 0.9° and 2° and MPOVs were slightly decreased at month 1 and increased after that. The increase reached statistical significance in local MPOD at 0.5° and 2° and MPOVs (Tukey–Kramer test). The changes in MPOV within 9° at year 2 [(MPOV on year 2 − MPOV on day 4) / MPOV on day 4] were from −0.21 to 1.18 (mean and standard deviation: 1.14 ± 0.28). The MPOV of 15 eyes increased more than 10% from the initial value, was maintained within 10% in 21 eyes, and deteriorated more than 10% in only 3 eyes. Conclusions Local MPOD and MPOV tended to slightly decrease month 1 postoperatively and gradually increased after that, but the rates of increases in MPOD levels were small. Yellow-tinted IOLs that have a lower transmittance of blue light might be preferable for preserving MPOD levels after surgery.

“…This is probably why the photoreceptor outer segments regenerated and visual acuity subsequently returned to normal. Since the patient's central scotoma began while she was gazing at the display of a Smartphone and the ring-shaped yellowish foveal reflex resembled that of solar retinopathy [3], acute light damage to the photoreceptors was highly suspected. However, the mechanism by which the light energy from the visual display of a Smartphone causes an acute photoreceptor light damage is unclear.…”

“…No abnormal findings were found in the right eye. Because of the resemblance of these findings to those of solar retinopathy [3], we diagnosed her with mild photoreceptor light damage caused by Smartphone gazing in the left eye. Ten days later, her BCVA improved to 20/25 OS, and the abnormal ring-shaped reflex became obscured in the central fovea ( Figure 1B), although the defects in the EZ and IZ were still present ( Figure 2B).…”

A woman in her twenties experienced a central scotoma in her left eye while she was gazing at the visual display of a Smartphone. Her Best Corrected Visual Acuity (BCVA) the following day was 20/15 OD and 20/60 OS. A ringshaped yellowish reflex surrounding the central fovea was observed in the left eye on a fundus photograph, and the inner segment Ellipsoid and Interdigitation Zones (EZ and IZ, respectively) were defective at the foveola on Optical Coherence Tomography (OCT). Ten days later, her BCVA became 20/25 OS. Although defects in the EZ and IZ remained, the fundus abnormality became obscured. Forty days later, her BCVA returned to 20/20 OS, her fundus findings appeared normal, and both EZ and IZ demonstrated nearly normal appearances. Although transient macular damage has been reported in young Patients after prolonged gazing at a computer game display, to our knowledge, this is the first report presenting similar OCT-detectable macular damage that is likely related to Smartphone usage. Since Smartphone’s have become exclusively popular all over the world among not only adults but also younger population, ophthalmologists should be aware that macular damage can occur in Smartphone users, particularly after gazing at the display under dim background illumination. Although such cases are rare, the damage is usually transient and spontaneously recovers after reducing the duration of Smartphone usage.

“…The damage from such exposure can start about 1 to 4 hours after exposure to a light source, with the main symptoms being metamorphopsia, central and pericentral scotoma, photophobia and mild to moderate loss of vision, which are commonly bilateral [1,3,4]. Solar retinopathy is caused by the direct or indirect observation of intense light sources and occurs mainly in individuals with psychiatric disorders, at religious events or after using recreational illegal substances [2,3,5].…”

“…In the acute phases, foveolar lesions can be seen, usually single, which tend to turn yellow in the days following exposure, and may be surrounded by an area of gray pigmentation (Table 1) [1,2,4,5].…”

Aims: To describe a solar retinopathy. Presentation of Case: ALPN, 29 years old, male, with cognitive deficit that started after a car accident that occurred at the age of 6 years, attends the ophthalmology clinic of the University Hospital Antônio Pedro, Rio de Janeiro, Brazil with complaints of decreased visual acuity and metamorphopsia in both eyes (AO) started approximately 8 months ago. Family members reported that after the accident, the patient had the habit of spending mornings and afternoons looking at the sun. Discussion: Solar retinopathy is caused by the photochemical and thermal effects of ultraviolet radiation on retinal cells, especially in the outer retina and retinal pigment epithelium (RPE). Symptoms can start a few hours after direct observation of the sun, and in most cases a bilateral involvement, although asymmetrically with variable visual acuity. Conclusions: A Solar retinopathy has a multifactorial origin, as it is related to the exposure time and the susceptibility of each individual. The use of hats and sunglasses with protection against ultraviolet rays and anti-reflection are effective preventive measures to be adopted if there is a need for exposure and observation of sunlight.
