“…This corresponds to the cases recently analyzed by Wolfe ( 1985 ) . He found that out of 23 cases collected from the literature (Balashevich et al 1981;Boldrey et al 1981;Curtin and Boyden 1968;Fowler 1983;Gayday Bleckmann and Zorn 1981; Prammer et al 1980). The factors between the actual energy entering the eye and the maximum permissible exposure calculated from the published data were in the same range as the cases reported here (while for the two cw lasers this factor is much less, i.e.…”

During the last decade, five patients with laser injuries were examined at the University of Munich Eye Clinic, in addition to one laser-injury patient at the University of Erlangen Eye Clinic. From a review of these cases, it is possible to gain an insight into factors that led to the eye injuries and to predict the clinical sequelae of laser retinal injury. A possible means of treatment, using an ophthalmic Q-switched Nd:YAG laser, is suggested for some types of retinal injury involving vitreal hemorrhage.

“…Accidental laser-induced injury to the human eye has been documented since the introduction of lasers (1,2,3,4,5). Retinal scarring, retinal traction, holes, and large scale photoreceptors loss can occur, depending on the characteristics of the laser beam, such as wavelength, pulse duration and energy, or beam power.…”

In vivo visualizing the dynamics of bone marrow stem cells in mouse retina and choroidal-retinal circulation

It has recently been shown that bone marrow cells can differentiate into various lineage cells including neural cells in vitro and in vivo.Therefore it is an attractive therapeutic intervention to apply autologous bone marrow-derived stem cells that may offer neuroprotection to laser-induced retinal injuries. The purpose of this study is to develop a method with which to visualize bone marrow stem cells dynamics in mouse retinal circulation. We have used a physiological method, confocal scanning laser ophthalmoscope (SLO), to track the highly enriched stem/progenitor cells circulating in the retina. Stem cells were enriched by immunomagnetic depletion of cells committed to the T-and B lymphocytic, myeloid and erythorid lineages. CellTracker TM Green-labeled stem cells were injected into the tail veins of mice with laser-induced focal retinal injuries. Bone marrow stem cells labeled with CellTracker TM Green were visible in the retinal circulation for as long as 1 hour and 30 minutes. These studies suggest that stem cell-enriched bone marrow cells may have the ability to mobilize into laser-induced retinal injuries and possibly further proliferate, differentiate and functionally integrate into the retina.

“…The minimum total intraocular energy needed to cause a macular hole is usually on the order of 1-3 millijoules (based on data from this laboratory and accident reports). 2,[5][6][7][8] Injury may also occur to adjacent retinal layers, with resultant fibrovascular scar formation. [9][10] Choroidal neovascularization may develop early or late in the wound healing process.…”

“…[11][12] Laser-induced macular holes typically result in varying degrees of permanent central visual loss. 2,[5][6][7][8] We have examined patients with accidental laser-induced macular holes and found decreased choriocapillaris perfusion on indocyanine green angiography. We sought to determine if this is common feature of laser induced macular holes.…”

Choroidal perfusion was evaluated following the creation of a laser induced macular hole in a nonhuman primate model. Two Rhesus monkeys underwent macular exposures delivered by a Q-switched Nd:YAG laser. The lesions were evaluated with fluorescein angiography and indocyanine green (ICG) angiography . Each lesion produced vitreous hemorrhage and progressed to a full thickness macular hole. ICG angiography revealed no perfusion of the choriocapillaris beneath the lesion centers. Histopathologic evaluation showed replacement of the choriocapillaris with fibroblasts and connective tissue. Nd:YAG, laser-induced macular holes result in long term impairment of choroidal perfusion at the base of the hole due to choroidal scarring and obliteration of the choriocapillaris.
