BACKGROUNDIt was well known that tangential vitreoretinal traction and epiretinal membrane play important roles during the formation of macular hole (MH) associated with retinal detachment (RD) in highly myopic eyes. But it was not clear about the correlations between anteroposterior traction, posterior vitreous cortex (PVC) and MH-RD. The vitreous status in highly myopic eyes were analyzed to explore the effect of PVC in the role of MH-RD formation.

METHODSSixteen consecutive highly myopic eyes with RD due to MH were retrospectively analyzed from January 2009 to April 2009. The preoperative examinations for detecting posterior vitreous detachment (PVD) and vitreoretinal traction included B-mode ultrasonography and optical coherence tomography (OCT). The residual PVC and PVD were confirmed intraoperatively during triamcinolone acetonide (TA) assisted vitrectomy.

RESULTSUnder ultrasonography, the preoperative PVD patterns were stratified as: complete PVD in three (19%) eyes, partial PVD in eight (50%) eyes, and no PVD in five (31%) eyes. OCT confirmed vitreoretinal traction and no complete PVD in 10 (63%) eyes, including anteroposterior traction in four eyes and tangential traction in six eyes. During TA-assisted vitrectomy, it was confirmed that no complete PVD existed in 16 eyes, including six eyes (38%) finally diagnosed of partial PVD, and five (31%) eyes with vitreoschisis. Anteroposterior vitreoretinal traction around MH is always in conjunction with partial PVD (67%), and high proportion (80%) of vitreoschisis is associated with tangential vitreoretinal traction. Comparing with the precision of TA staining of PVD diagnosis, the coincidence rate of ultrasonography was 69% (P = 0.02), and that of OCT was 63% (P < 0.01).

CONCLUSIONSThe residual PVC due to partial PVD or vitreoschisis may cause the anteroposterior or tangential traction of macular area, which contributes to the formation of MH and subsequent RD in highly myopic eyes. And it is necessary to realize the vitreoretinal relationship and assess the status of PVC synthetically for surgery by combined ultrasonography and OCT preoperatively and TA staining intraoperatively.

The occurrence of a retinal detachment in a patient with a macular hole is quite rare unless the patient is a high myope or has experienced ocular trauma. The incidence of spontaneous reattachment of retinal detachment with a macular hole is not uncommon in the highly myopic patients. However, data on nonmyopic cases are lacking. I herein describe two nonmyopic cases of retinal detachment with a macular hole, of which retinas reattached spontaneously.

OBJECTIVESTo explore the changes of multifocal electroretinograms (mfERG) before and after retinal detachment surgery and to evaluate its clinical significance.

METHODSTwenty-three patients (23 eyes) with rhegmatogenous retinal detachment underwent mfERG before and after surgery. The latencies and average response densities of N(1)-wave and P(1)-wave of mfERGs in detached areas, attached areas, fovea and the entire tested area were compared before and after surgery.

RESULTSPreoperatively, the average response densities of N(1)-wave and P(1)-wave in the detached area were significantly smaller than those in attached areas (t = 3.68, t = 4.26, P < 0.01), and the latencies of N(1)-wave and P(1)-wave in detached areas were significantly longer than those in attached areas (t = 3.07, t = 3.89, P < 0.01). Postoperatively, the average response densities of N(1)-wave and P(1)-wave in detached areas, fovea and the entire tested area increased, and there were significant differences pre- and postoperatively (P < 0.05). However, the latencies of N(1)-wave and P(1)-wave before and after surgery showed no significant differences (P > 0.05).

CONCLUSIONSThe mfERG is a useful tool to evaluate the recovery of posterior retinal function after retinal detachment surgery. The response density is a more sensitive index than latency to evaluate retinal function of retinal detachment.

Changes in the scotopic electroretinogram (ERG) and oscillatory potentials (Ops) were examined in patients who had rhegmatogenous retinal detachment within 3 days before and also at regular intervals after a successful reattachment operation. Electroretinograms were recorded in 38 patients (age 10 to 62 years) for the recent 5 year period. The amplitudes of the scotopic a-wave and b-wave in the detached eye were significantly decreased compared to the fellow normal eye preoperatively. Statistically significant differences were found between the preoperative and the postoperative recordings of the diseased eye. However, postoperative interocular differences in the amplitude of the a-wave between the reattached and normal fellow eye were not statistically significant. The amplitudes of the a-wave and b-wave were inversely related to the extent of the retinal detachment area, the duration of the detachment, and the extent of the buckles that were applied. Significant interocular differences in the b/a wave amplitude ratio and the Ops amplitude were observed. These results strongly suggest that the retinal function, even after successful reattachment surgery, might be compromised mainly by an inner retinal malfunction rather than from a photoreceptor dysfunction.

This retrospective observational case series on eyes from three patients was done to elucidate the developmental mechanism of spontaneous reattachment of rhegmatogenous retinal detachment (SRRRD). The study eyes of each patients showed evidence of retinal break and diffuse retinal pigmentary change. Ultrasound biomicroscopic examination revealed vitreous fibers attached to the area around the retinal break. Posterior vitreous attachment was confirmed in each eye. A thin fibrovascular membrane incompletely sealing the retinal break was noted in one case. We suggest that the vitreous attachment around the retinal break and the sealing of the break with adjacent vitreous fibers seem to be involved in the developmental mechanism of SRRRD.

PURPOSE: To investigate correlated factors on final visual acuity in conjunction with fluorescein angiography (FA) and optical coherence tomography (OCT) findings of chronic central serous chorioretinopathy (CSCR). METHODS: Twenty-four patients (36 eyes) with typical findings of chronic CSCR based on medical records, FA and OCT results were enrolled in this study. We investigated demographic findings, initial and final visual acuity (VA), and some typical findings of FA including the type of leakage pattern, the existence of a gravitational tract and an abnormal hyperfluorescent area centered on the fovea. We also investigated OCT findings to examine serous retinal detachment, outer photoreceptor layer (OPRL) preservation, continuity of the inner segment (IS) and the outer segment (OS) of the photoreceptor layer in case of macular attachment, and other typical findings. The converted logarithm of the minimum angle of resolution VA was used to investigate the statistical correlation with these FA and OCT findings. RESULTS: An abnormal hyperfluorescent area within 1 macular photocoagulation study disc area on FA and cystoid degeneration on OCT were correlated with poor final VA of less than 20 / 40. However, the preserved OPRL and the continuity of IS / OS junction were correlated with a good final VA of 0.5 or more. CONCLUSIONS: These specific findings could be associated with recurrent or persistent subretinal fluid and could be important parameters of decision for treatment.

PURPOSE: To evaluate the clinical features and surgical outcomes for primary rhegmatogenous retinal detachments (RDs) in patients with pseudophakia after phacoemulsification. METHODS: The medical records of patients with pseudophakia after phacoemulsification and intraocular lens implantation who had undergone surgery for primary rhegmatogenous RDs with a minimum duration of follow-up of 12 months were reviewed retrospectively. RESULTS: A total of 104 patients were enrolled in this study and 106 eyes were analyzed. Post-operative retinal attachment was achieved in 87 of the eyes (82.1%) and the final visual acuities (logarithm of the minimum angle of resolution) were improved to 0.65 +/- 0.49 from the baseline measurement of 1.51 +/- 1.14 (p < 0.001). Re-operations were performed in 24 of the eyes (22.6%) and there were no visible retinal breaks in 30 of the eyes (28.3%). The failure to identify a retinal break during surgery was associated with a lower rate of retinal reattachment, worse final visual acuity, and a higher rate of re-operation (p = 0.002, p = 0.02, and p = 0.002, respectively). The location of the identified retinal break was more common in the superotemporal quadrant than in the other quadrants. CONCLUSIONS: The inability to identify a retinal break during surgery was associated with a poor final outcome. Other factors were less important for the functional and anatomic success in patients with pseudophakic RDs.

OBJECTIVETo investigate corneal refractive changes after scleral buckling surgery.

METHODSIn a prospective self-controlled clinical study, we investigated the changes of refractive power, astigmatic power, astigmatic axis, and irregular astigmatic power of anterior corneal surface following scleral buckling surgery for retinal detachment in 30 patients (30 eyes). The corneal shapes were detected by Orbscan II topography at 1 day before surgery, and 1 week, 1 month, and 3 months after surgery. The effects of some surgical factors on the anterior corneal refractive changes were analyzed.

RESULTSAfter surgery, refractive power on corneal anterior surface decreased significantly in peripheral zone at 1 week (P < 0.01). Astigmatic power increased obviously in central zone. The direction of astigmatic axis matched the direction of the buckle, and changed obviously in central zone after 1 week (P < 0.05). Irregular astigmatic power did not change significantly. There was a significant correlation between the encircling length/the buckle width and the refractive changes of corneal anterior surface.

CONCLUSIONRefractive changes of corneal anterior surface following scleral buckling surgery was mainly temporary. Changes in the shape of corneal should be minimized to ensure a favorable postoperative visual acuity.
