1/7. vitrectomy with internal limiting membrane peeling for macular retinoschisis and retinal detachment without macular hole in highly myopic eyes.

    PURPOSE: To report anatomic and visual improvement following vitrectomy with internal limiting membrane (ILM) peeling for two highly myopic patients with retinoschisis and/or retinal detachment without a macular hole. DESIGN: Two interventional case reports. methods: Two highly myopic patients who had retinoschisis and/or retinal detachment without a full-thickness macular hole underwent vitrectomy, internal limiting membrane peeling, and long-acting gas injection. Main outcome measures included best-corrected visual acuity, biomicroscopic appearance, and optical coherent tomography finding. RESULTS: vitrectomy with ILM peeling results in biomicroscopic, functional, and tomographic improvement in both patients, for follow-up periods of 12 months and 8 months, respectively.CONCLUSIONS: vitrectomy with ILM peeling and gas tamponade is an effective method for retinoschisis and/or retinal detachment without a macular hole in highly myopic patients.

2/7. retinal detachment 7 years after prophylactic schisis cavity excision in juvenile X-linked retinoschisis.

    A 7-year-old boy with X-linked juvenile retinoschisis developed a retinal detachment at the site of previous prophylactic excision of a schisis cavity. The patient underwent a scleral buckle procedure, pars plana vitrectomy, membrane peel, and silicone oil injection with successful reattachment. At last follow-up, the visual acuity was 20/400 and the retina was attached. Prophylactic excision of a schisis cavity may be complicated by retinal detachment several years after the surgery. Given the favorable natural history of schisis cavities in X-linked juvenile retinoschisis, the decision to perform prophylactic excision should be undertaken cautiously after full consideration of the potential complications.

3/7. Vitreal pathogenic role in optic pit foveolar retinoschisis and central serous retinopathy.

    PURPOSE: To expand on current theories concerning the vitreal-induced mechanism underlying the development of foveolar retinoschisis and macular sensory detachments associated with optic nerve head pits. To propose the notion that vitreal traction may contribute to the pathogenesis of serous detachments in central serous chorioretinopathy (CSC). REPORTS: We describe two patients, one with macular retinoschisis and the other with central serous detachment. The first patient, a 45-year-old Hispanic female, presented with a temporally located optic nerve head pit, foveolar retinoschisis and schisis retinal spaces extending to the surrounding macula and to the disc. The second patient, a 43-year-old Haitian male, developed a central serous retinal detachment OS with decreased visual acuity one day following in-office administration of Apraclonidine (0.5 per cent Iopidine, Alcon) and Dorzolamide-timolol Maleate (Cosopt, Merck) to lower elevated intraocular pressure (IOP). Macular retinal pigment mottling and epiretinal membrane sheen OU had been observed on his initial visit. visual acuity improved within a three-day period with resolution of the serous detachment. CONCLUSION: We suggest that the persistence of Cloquet's canal may permit fluid leakage into the proximal vitreous in cases of congenital optic nerve head pits. Tangential vitreal traction may promote the opening of a fistula at the optic pit and additionally thrust vitreal fluid into the pit and retinal space inducing the formation of schisis spaces, foveolar-schisis and underlying sensory serous detachment. We question whether a reduction in vitreous volume, induced by initial administration of anti-glaucoma medications, may contribute to the development and/or recurrence of central serous choroidopathy in predisposed individuals.

4/7. Posterior vitreous detachment and macular hole formation in myopic foveoschisis.

    PURPOSE: To report two cases of macular hole (MH) associated with myopic foveoschisis (MF). DESIGN: Interventional case report. methods: Two women presented with metamorphopsia. Preoperative optical coherence tomography (OCT) showed an MH and MF. We performed vitrectomy, internal limiting membrane (ILM) peeling and gas tamponade. RESULTS: Preoperative OCT examination and intraoperative microscopic observation revealed partial posterior vitreous detachment (PVD) at the posterior retina and vitreous strands adhering to the edge of the MHs. The MF resolved in both patients, but the MHs remained open postoperatively. CONCLUSIONS: Although the contribution of tangential traction cannot be excluded, the mechanism of MH formation in eyes with MF may be anteroposterior traction via abnormal vitreofoveal adhesion resulting from partial PVD.

5/7. STRATUS optical coherence tomography in unilateral colobomatous excavation of the optic disc and secondary retinoschisis.

    PURPOSE: To report the STRATUS optical coherence tomography (STRATUSOCT) findings in a patient with unilateral coloboma-like excavation of the optic disc without pit but secondary retinoschisis, as well as to discuss the possible involved pathophysiologic mechanisms. methods: Observational case report. STRATUSOCT findings in a 66-year-old woman with a coloboma-like excavation of the optic disc without pit but secondary retinoschisis encompassing the macular region, along with evidence of a mild epiretinal membrane superonasal to the disc were evaluated. RESULTS: STRATUSOCT showed signs of a connection between the perineural space and the inner retinal layers on the temporal optic disc border, as well as schisis-like changes extending from the disc to the macula, with cystoid degeneration and two lamellar holes in their nasal portion. CONCLUSION: The use of third generation OCT afforded an enhanced visualization of retinal structures, revealing signs of fluid at several distinct levels, as well as deep and superficial inner breaks apart from the schisis cavity. We are unaware of such previous reports, and could find no reference to them in a computerized search using medline. In addition, our study supports a common pathomechanism for the development of macular complications in optic pits and colobomas.

6/7. vitrectomy for myopic posterior retinoschisis or foveal detachment.

    PURPOSE: To evaluate the efficacy of vitrectomy for posterior retinoschisis (RS) or foveal detachment (FD) associated with posterior staphyloma in myopic eyes. methods: We reviewed the records of 14 consecutive patients (53-77 years of age; 16 eyes) with progressive visual impairment as a result of myopic RS or FD. Optical coherence tomography demonstrated the presence of a variety of RS and FD characteristics. Five eyes had RS alone, and 11 eyes had RS and FD. Two eyes with RS and severe FD developed retinal detachment in conjunction with a tiny macular hole. vitrectomy, including posterior vitreous separation in all eyes and internal limiting membrane (ILM) peeling in six eyes, had been performed. The patients were followed postoperatively for 6 to 66 months (mean, 24 months). The anatomical outcome and visual acuity were retrospectively analyzed in this study. RESULTS: Although the two eyes with RS and severe FD developed retinal detachment with a macular hole after an initial vitrectomy, final retinal reattachment was achieved in all 16 eyes. visual acuity improved in nine eyes and remained unchanged in seven eyes. CONCLUSIONS: vitrectomy with posterior vitreous separation is effective for reattaching the macula and preventing a deterioration of vision, although eyes with RS and severe FD may be at risk for the development of a macular hole after the initial vitrectomy.

7/7. reoperation for persistent myopic foveoschisis after primary vitrectomy.

    PURPOSE: We performed vitrectomy on two eyes for persistent myopic foveoschisis (MF) after primary surgery that did not include internal limiting membrane (ILM) peeling. DESIGN: Interventional case reports. methods: Two highly myopic eyes of two patients with persistent MF after primary vitrectomy and gas tamponade but without ILM peeling were treated with pars plana vitrectomy, residual vitreous cortex removal, ILM peeling, and long-term gas tamponade. RESULTS: Total foveal reattachment was achieved and best-corrected visual acuity (BCVA) improved in both eyes. CONCLUSIONS: reoperation including complete vitreous cortex removal and ILM peeling could be beneficial for patients with persistent MF after primary surgery, indicating that vitreous cortex removal and ILM peeling are critical in treating MF.
