          Abstract

          The use of endotamponade agents has gained a major role in the management of macular complications of high myopia. Myopic foveoschisis and macular hole are the main macular complication of pathologic myopia, this growing condition that is a main cause of visual loss, especially in patients at a younger age. We discuss the physical properties and advantages and disadvantages of the main ocular tamponade agents used in the treatment of these diseases.

          Foveal retinoschisis and retinal detachment in severely myopic eyes with posterior staphyloma.

          To evaluate the tomographic features of the retina in patients with severe myopia and posterior staphyloma. In a prospective study of 32 eyes of 19 consecutive patients with severe myopia and posterior staphyloma, we performed complete ophthalmic examinations and studied cross-sectional images of the macula with optical coherence tomography. Patients' age ranged from 41 to 83 years (average, 62.7 years). Best-corrected visual acuity ranged from 20/500 to 20/40 (average, 20/120). The study included 26 phakic and six pseudophakic eyes. The refractive errors of 26 phakic eyes ranged from -8 to -31 diopters (average, -16.7 diopters). Although refractive errors were within -8 diopters in six pseudophakic eyes, the eyes had apparent posterior staphyloma. The axial lengths measured by A-mode ultrasonography ranged from 25.7 to 32.7 mm (average, 29.2 mm). Slit-lamp examination with contact lens showed that none of the eyes had a macular hole. In nine eyes with shallow retinal elevation on slit-lamp examination, optical coherence tomography disclosed a foveal retinal detachment with retinoschisis in eight eyes and a foveal retinal detachment in one eye. Two of the remaining 23 eyes had retinoschisis. Foveal retinal detachment and retinoschisis are common features in severely myopic eyes with posterior staphyloma. Retinal detachment may precede the formation of a macular hole in severely myopic eyes.

            Vitreous surgery for highly myopic eyes with foveal detachment and retinoschisis.

            To evaluate the efficacy of vitreous surgery for highly myopic eyes with foveal detachment and retinoschisis. Retrospective comparative interventional case series. Seven patients (nine highly myopic eyes) with posterior staphyloma with foveal detachment and retinoschisis without macular hole. Preoperative best-corrected visual acuity in nine eyes ranged from 0.02 to 0.4 (average, 0.17). Vitreous surgery performed on all nine eyes consisted of core vitrectomy, surgically induced posterior vitreous detachment (three eyes), removal of the premacular vitreous cortex and internal limiting membrane in the posterior staphyloma, and 30% SF(6) gas tamponade. Patients were instructed to maintain a prone position for at least 1 day after surgery. The postoperative follow-up period ranged from 6 to 42.5 months (average, 20.4 months). Visual acuity, retinal tomography monitored by optical coherence tomography. In eight of the nine eyes, foveal detachment and retinoschisis gradually decreased in height, and these eyes finally attained foveal attachment and visual improvement within 6 months postoperatively. The postoperative best-corrected visual acuity of these eight eyes ranged from 0.4 to 0.6 (average, 0.48). One eye developed a full-thickness macular hole during vitreous surgery, and its postoperative best-corrected visual acuity was 0.08. Foveal detachment and retinoschisis in highly myopic eyes resolved after vitrectomy. Vitreous surgery might have a rationale as prophylactic treatment for highly myopic eyes at high risk of macular hole development.
