Objective: We report a case of a scleral buckle mimicking an orbital tumor 28 years after a retinal detachment repair. Methods: This is a case report. Results: A 75-year-old male consulted for progressive, painless blurred vision of the right eye. He had a history of scleral buckling surgery for retinal detachment on the right eye in 1990 that restored his vision. Examination showed right eye ophthalmoplegia and inferior displacement of the globe. Imaging revealed a right supero-temporal orbital mass. Excision of the encapsulated mass was performed. Histopathology revealed an acellular, amorphous, granular and eosinophilic material with no evidence of malignancy. These were consistent with a foreign body. Postoperatively, there were improvements in ocular motility and hypoglobus. Conclusion In patients who present with limited ocular motility and have undergone scleral buckling, hydrogel scleral buckle overexpansion should be considered. Excision of such implants is warranted to resolve the signs and symptoms and confirm the etiology.

Pars plana vitrectomy with encircling scleral buckling was performed for 30 eyes of 30 patients with complicated retinal disorders, and the changes of axial length, refractive power, and corneal curvature were analyzed. Significant axial length elongations were observed after encircling procedures. Mean elongation was 0.93+/-0.48mm after 3 months and 0.91+/-0.54mm after 6 months. These spherical equivalent of refraction showed myopic shift of -2.26+/-1.51 diopters(D) after 3 months and -2.19+/-1.39D after 6 months. These changes seem to be less prominent in the eyes with preoperative axial length of 24.50mm or longer(0.68+/-0.46mm after 3 months, 0.60+/-0.49mm after 6 months) than in the eyes with axial length of 24.49mm or shorter(1.18+/-0.35mm 1.23+/-0.38mm). Slight increase in astigmatism was observed, 0.80+/-1.35D after 3 months and 0.64+/-1.01D after 6 months. The mean keratometric readings showed no significant changes, 0.00+/-0.95D after 3 months and 0.26+/-0.95D after 6 months. The result of this study may give an important information when combined procedure of encircling scleral buckling and IOL implantation be planned.

PURPOSE: To evaluate the effect of scleral buckling and pars plana vitrectomy on accommodative power. METHODS: The study groups consisted of 30 eyes after buckling and 30 eyes after pars plana vitrectomy. Each control group comprised 30 eyes. Accommodative power, pupil diameter and anterior chamber depth were measured and the correlation coefficient to accommodative power was calculated. RESULTS: There was no statistical significance in the buckling group. In the pars plana vitrectomy and control groups, the accommodative powers were 4.03 +/- 2.30D and 2.26 +/- 2.70D (p<0.05), and the pupil diameters were 3.07 +/- 1.06 mm and 3.99 +/- 2.71 mm (p<0.05), respectively. Age and pupil diameter had a significant correlation coefficient in all groups (r>0.8 or r<-0.8). CONCLUSIONS: After pars plana vitrectomy, the accommodative power was increased, which suggested that the anatomical and structural change of the vitreous after pars plana vitrectomy influences the accommodative power.

We evaluated the degree of ptosis, the function of levator muscle, and postoperative interval to recovery of ptosis in 20 patients who underwent scleral buckling for retinal detachment. The MRD 1(Margin reflex distance 1), function of levator muscle by Berke method and interpalpebral fissure height were evaluated at preoperative day and 1, 3 days, 1, 2, 4, 6, 8, weeks, and 6 months after surgery. The results were compared according to age, gender, extent of buckling, location of buckle. All patients were reported to develop ptosis at postoperative day one, and 20% of them showed mild ptosis persistent until 8 weeks after surgery. The decrement of MRD 1 was statistically significant until postoperative 2 weeks, but impaired function of levator muscle was statistically significant until postoperative 6 weeks(P<0.05). The postoperative interval to recovery of MRD 1 was delayed in group of old age(order than 40 years), in male and when the buckle was located under the superior rectus muscle(P<0.05). The postoperative interval to recovery of function of levator muscle was delayed in group of female, when the buckle extent was more than 180 degrees and when the buckle was located under the superior rectus muscle(P<0.05).

PURPOSE: To investigate the postoperative changes and the mechanism of retinal reattachment, the geometric changes of the eye with an encircling scleral buckle was analyzed using a simplified eye model. METHODS: The simplified eye model is an inelastic sphere with an external diameter of 25 mm and an internal diameter of 23.6 millimeters. With an encircling scleral buckle, it was assumed that the circumference of the eyeball would decrease, and in particular with tightening of the buckle, the cross-section of eyeball would be deformed to an ellipsoid shape. The changes in radius, internal surface area, and volume of the eyeball in relationship to the changes in height and span of the silicone buckle were estimated. RESULTS: The radius of eyeball decreased by 0.19-0.90 mm with an encircling scleral buckle, and varied according to the increment of the tightening of the encircling band. The axial length of the eye increased and the volume of the eye decreased also with increased tightening of the band. The scleral arc of the buckle was shorter than the retinal arc of the buckle by 0.09-0.55 mm and the scleral surface area of the buckle was smaller than the retinal area of the buckle by 56-219 mm 2 ; therefore the retina would be redundant. CONCLUSIONS: An encircling scleral buckle changes the axial length and decreases the volume and internal surface area of the eye, making the retina redundant. This redundancy helps resolve or alleviate the problem of a foreshortened retina in retinal reattachment procedures.

Rarely, break in the non-pigmented epithelium in the pars plicata can occur and sometimes develop into retinal detachment. We experienced a case of retinal detachment associated with lens coloboma in 34-year-old male. A break in the non-pigmented epithelium in pars plicata was found with retinal detachment. We treated the break by cryoapplication, scleral buckling and encircling.

The hypotony with cyclodialysis after blunt trauma to the eye rarely happens and the cyclodialysis is diagnosed by finding the cleft in the anterior chamber anglel It is treated with cycloplegics conservatively or with surgery. In this study, the authors reviewed the hyphema, the onset of hypotony, the size of cyclodialysis cleft and transient scleral buckling that is one of the surgery in 7 eyes of 7 patients . The hyphema was seen in all cases after blunt trauma to the eyes and the duration between the trauma and the onset of hypotony was average 7.2 days. The traumatic cyclodialyses clefts were half an clock hour in 3 patients and 1 to 4 clock hours in 4 patients . Six patients had an initial conservative treatment, 3 patients required surgical treatment, scleral buckling, for 3 weeks for the full recovery of intraocular pressure.

12 cases of retinal detachment treated with scleral buckling Procedure of 4392 visitors the department of ophthalmology. Yonsei University medical school from Feb. 28th 1958 to April 30th 1959. 30 cases of retinal detachment were found 12 cases out of 30 received the scleral buckling procedure, and exhibited the following results. 1) a. Successful, b. Fair 3(25%), c. Failure 2(16.6%). 2) The shorter the duration of retinal detachment existed the better the resutls of the operation was. However in 2 cases of old retinal detachment lasted more than 7 months the results of the operation were also successful. 3) Results of the surgery were more favourable in the cases of having no definite hole. 4) In one case, retinal detachment was recurred a year after the first procedure and a secondary procedure was performed with fair results.

Pneumatic retinopexy is a recently described procedure to treat the uncomplicated retinal detachment. The procedure of pneumatic retinopexy is composed of cryotherapy (or laser photocoagulation), intraocular gas injection and postoperative positioning. The advantages of pneumatic retinopexy are less tissue trauma, no hospitalization and minimal complication. For these reasons it is more and more popular, but further studies are needed to assess its ultimate safety and efficacy. The authors experienced 7 cases of primary rhegmatogenous retinal detachment treated with pneumatic retinopexy, from September, 1987 to March, 1988. Four cases of the retinal detachment were successfully reattached after pneumatic retinopexy. In the other 3 cases, new retinal tear and detachment were found after pneumatic retinopexy, which were successfully repaired with the conventional scleral buckling procedure.

Scleral buckling used alone to treat retinal detachment with proliferative vitreoretinopathy(PVR) of grade C resulted in an overall anatomic reattachment rate of 86%(39/45); 96%(27/28) in stage C1, 83%(10/12) in stage C2, and 40%(2/5) in stage C3. The success rate declined with increasing severity of PVR. Stage C3 eyes showed a significantly lower rate of retinal reattachment than stage C1 and C2 eyes(p<.05). We currently recommend scleral buckling alone as the surgery of choice for stage C1 and C2 PVR; we reserve vitrectomy with preretinal membrane removal for the more advanced cases.
