“…It has been shown (Noell et a/., 1966;Kuwabara and Gorn, 1968;Lawwill, 1973; Ham et a/., 1976) that visible light may cause considerable damages to the retina. Noell and co-workers (1966) provided the initial evidence by observing visual cell death in rats left for 1 week under filtered fluorescent light.…”

Abstract. All trans‐retinal has been introduced (2 mol %) into artificial membranes made up of egg lecithin, cholesterol and dicetyl phosphate. Illumination of retinal‐enriched liposomes at 365 nm induced photodynamic damages; it triggered the sensitized oxidation of the lipids measured by the appearance of a 233 nm absorption band or by the formation of malonyl dialdehyde. Illumination produced an increase of the membrane fluidity detected with the spin label technique and led also to the lysis of the liposomes as revealed by the release of entrapped chromate ions or by changes in light scattering. Singlet oxygen is involved in these photodynamic effects. The results have been discussed in connection with the light damage phenomena which may afflict the rod outer segment membranes.

“…These studies have identified the primary sites of argon laser damage and also indicated that structural changes continued to develop after the laser application and may extend to non-coagulated areas. Expansion of laser damage to non-coagulated areas was also implicated from electroretinographic measurements from diabetic patients and laboratory animals that were treated with argon laser [7,11,16,17]. This suggestion was supported by a morphological study in the rabbit retina that demonstrated glial fibrillary acidic protein (GFAP) immunoreactivity in Müller cells located as far as 2±3 mm from the laser lesion [10].…”

The immediate laser damage is confined to the coagulated areas while secondary functional damage develops within 24 h and probably reflects serous retinal detachment between lesions. The serous retinal detachment completely resolves with time but may induce permanent structural abnormalities in non-coagulated retinal areas that is reflected in a functional deficit larger than the initial laser effect.

“…However, tests of peripheral visual function have revealed quite noticeable deficits in PRP-treated diabetic persons. Such tests of peripheral function include the EOG and scotopic ERG (Lawwill and O'Connor, 1972), perimetry (Frank, 1975) and dark adaptation (Frost-Larsen et al, 1981).…”

A “Hidden” Deficit in Central Vision in Diabetic Pan‐retinal Photocoagulation Patients

Adaptation ability in the center of vision was tested in diabetic patients treated with pan-retinal photocoagulation for diabetic retinopathy and in normal control subjects. This was accomplished with a specially designed contrast sensitivity testing regimen. Patients with retinopathy showed "hidden" deficits, losses in adaptation ability that could not be measured by standard clinical tests, such as visual acuity. This new test thus quantifies a previously unmeasured visual problem that affects the everyday visual function of these patients.
