To report the surgical outcome of full-thickness sclerotomy in five cases of uveal effusion syndrome (UES). Full-thickness sclerotomy without sclerectomy was performed on five eyes of four patients with UES with or without nanophthalmos. In four of the eyes, exudative retinal detachment associated with UES resolved after the sclerotomy. The subretinal fluid in one eye, which had a normal axial length, was relieved after undergoing three sclerotomy procedures. Full-thickness sclerotomy without vortex vein decompression or sclerectomy is an effective surgical option for the management of significant UES.

PURPOSE: To investigate serial changes in photoreceptor status and associated visual outcome in patients with persistent submacular fluid after successful scleral buckle surgery for macula-off rhegmatogenous retinal detachment. METHODS: This was a prospective observational case series including 76 consecutive patients who underwent successful scleral buckle surgery for macula-off rhegmatogenous retinal detachment with symptom duration < or =90 days at a single tertiary hospital. Optical coherence tomography (OCT) and visual acuity examination were performed at one month and three months postoperatively and at three-month intervals until the submacular fluid disappeared. Main outcome measures were postoperative photoreceptor status on OCT and visual acuity. RESULTS: Forty-two patients (55.3%) showed persistent submacular fluid at postoperative one month. Of 42 patients with persistent submacular fluid, three (7.1%) showed photoreceptor disruption on OCT. None of the 34 patients without persistent submacular fluid showed photoreceptor disruption. Two patients (4.8%) had progressive photoreceptor disruption, and one patient (2.4%) had early photoreceptor disruption. All three patients showed photoreceptor reappearance and limited visual restoration after absorption of submacular fluid. Final visual acuities were significantly worse in these three patients (20 / 1000, 20 / 133, and 20 / 133) compared to those of the other patients (mean, 20 / 30) with persistent submacular fluid and intact photoreceptors. CONCLUSIONS: Even after successful scleral buckle surgery for rhegmatogenous retinal detachment, photoreceptor disruption can occur related to persistent submacular fluid and may be a cause of poor visual outcome.

OBJECTIVE: To demonstrate the mechanism of positive effects of the sequential air-fluid exchange on the use of complicated vitroretinal microsurgery. METHODS: Seventy-one patients who underwent vitreoretinal microsurgery were performed 2 or 3 times sequential air-fluid exchange. The regenerated fliud in vitreous cavity at various periods was collected to act on cultured human retinal pigment epithelial (RPE) cells,and then the secretion of bFGF and the expressions of bcl-2 and ki-67 by RPE cells were observed. RESULTS: The expressions of bcl-2 and ki-67 were up-regulated and the secretion of bFGF significantly increased after RPE cells was acted with the regenerated fluid in the vitreous cavity. CONCLUSION The sequential air-fluid exchange can mechanically reduce intraocular growth factors after the vitreoretinal microsurgery, indirectly restrain the proliferation of RPE cell, and improve the successful rate of vitreoretinal microsurgery.
