ABSTRACT
Caso Clínico: Paciente varón de 28 años, que tras traumatismo contuso en su ojo izquierdo, presenta una hipotonía ocular persistente (presión ocular 4 mmHg) acompañada de pérdida de agudeza visual (0,4), edema de papila y pliegues coriorretinianos a nivel macular. El grosor foveal, medido con tomografía de coherencia óptica, era de 326 micras. Mediante biomicroscopia ultrasónica se aprecia una desinserción de iris nasal y un desprendimiento coroideo de 360°. El cuadro no cede con tratamiento conservador, por lo que 10 meses tras el traumatismo se le realiza una ciclopexia transescleral con láser diodo de contacto. Un año tras la aplicación del láser, la agudeza visual era 1, la presión ocular 14 mmHg y el grosor foveal 240 micras. Discusión: La ciclopexia transescleral con láser diodo puede ser una alternativa eficaz para la resolución de ciclodiálisis postraumáticas que no responden a tratamiento médico
Case report: A 28-year-old man who received a blunt trauma in his left eye, presented with persistent ocular hypotony (intraocular pressure: 4 mmHg) as well as loss of visual acuity (0.4), optic disc edema and chorioretinal folds in the macula. The foveal thickness, measured by optic coherence tomography, was 326 microns. Using ultrasound biomicroscopy, a desinsertion of the nasal iris and a 360º choroidal detachment was observed. The hypotony did not respond to conservative treatment and 10 months after the trauma he underwent a transscleral cyclopexy with contact diode laser. One year after the laser treatment the visual acuity was 1.0, the intraocular pressure 14 mmHg and the foveal thickness 240 microns. Discussion: Transscleral cyclopexy with diode laser may be an effective alternative treatment to resolve post-traumatic cyclodialysis that does not respond to medical treatment (Arch Soc Esp Oftalmol 2009; 84: 47-50)

Focal gamma irradiation was used to limit the intraocular extension of scar tissue which typically occurs after posterior perforating injury to the eye. Standard posterior perforating injuries were created in the right eye of forty-eight rabbits, half of which had the site of perforation focally irradiated using a Cobalt 60 ophthalmic plaque. Non-irradiated wounds healed with profuse formation of highly cellular and vascularised granulation tissue which invaded the vitreous to form contractile vitreo-retinal membranes. In irradiated eyes vitreo-retinal membrane formation was infrequent; the wounds showing only sparse granulation tissue with little or no extension into the vitreous cavity. Autoradiographic studies carried out in a second group of 40 animals showed that the episclera was the main source of the proliferating fibroblasts, and cell counts confirmed that the inflammatory and repair responses in irradiated wounds were both delayed and attenuated.
