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.

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.

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.
