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.

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.

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 present a case of the acquired Brown syndrome caused by scleral buckling. METHODS: A 58-year-old man presented with floaters in his right eye which had developed 20days before. Rhegmatogenous retinal detachment with a retinal tear at the location of 2 o' clock was diagnosed. Radial scleral buckling was performed. Ten days after surgery, he was unable to elevate his right eye in adduction, and right superior oblique muscle overaction was presented. RESULTS: Acquired Brown syndrome caused by scleral buckling has not been documented in Korea to our knowledge. Therefore, we report this case with review of related literatures.

There has been a series of reports indicating that scleral buckling[SB] surgery may induce high myopia in advanced retinopathy of prematurity. The mechanism of SB on refraction, however, has not been clearly known. We investigated the effects of SB on eyeball in young rabbits, including mechanism of refractive change. In 9 rabbits with 5 weeks old[Group A]and 11 rabbits with 8 weeks old[Group B], SB was performed for right eyes of all rabbits with encircling band, 2.5 mm in width.Left eyes of these were followed up for control group. Spherical equivalent, corneal power, and axial length were measured before SB and at 2, 4, and 8 weeks postoperatively. We compared these measures between experimental and control groups, and analyzed the influence of age at operation. In control group, corneal refractive power was decreased, axial length was increased, and spherical equivalent developed emmetropization in aging. High myopia was developed in all eyes with SB, and the increase of axial length was the major factor in myopia.These changes were greater in group A than group B.In experimental group, the degree of myopia was increased at 4 and 8 weeks postoperatively, but corneal power and axial length were not statistically changed. In conclusion, the SB in younger rabbits induced higher degree of axial myopia.These findings may suggest that SB in infant could induce significant axial myopia and secondary amblyopia, especially younger age.

By means of slit-lamp biomicroscopy of posterior segment of the eye specific indications for open-sky subtotal vitrectomy are (1) recently established massive periretinal proliferation where multiple scleral buckling procedures have failed. (2) adhesion of the retina to anterior segment structures and (3) extensive adhesion of vitreous strands and membranes to the detached retina. Seven cases were operated between June to December 1978 by open-sky technique which seemed incurable by conventional retinal surgery. The operations resulted success rate in 3 out of 7 cases, which have been followed for at least 10 months. The results appeared to justify an aggressive approach to open-sky vitrectomy.

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.

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.

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.
