The pilot study of transscleral diode laser retinopexy by Haller et al,¹ published in the July 1993 issue of the ARCHIVES, showed the feasibility of transscleral retinopexy during retinal detachment surgery. The treatments were called effective and safe, yet the energies used were high and choroidal rupture occurred in 30% of eyes.

Effectivity.

If the target tissue is the pigment epithelium, then the transscleral radiation has to pass through choroid. However, the outer choroid is maximally pigmented and considerable absorption takes place before light reaches the pigment epithelium. Large amounts of energy are required to penetrate the choroid. The figures in the article by Haller et al¹ demonstrate the extensive choroidal necrosis and atrophy and Table 1 shows energies to be in the range of 74 to 1492 J, with a mean energy of 520 J.¹ It is of note that five of the eyes in the . . .
