Pneumatic retinopexy is known as one of the treatment options for a specific type of retinal detachment. It is done in an office setting and may be the most cost-effective means of retinal reattachment surgery. Location and size of the retinal break remain as the major criteria for a successful outcome. We describe a case that fulfilled all except one major criteria for pneumatic retinopexy and underwent multiple procedures but failed. Fluctuation in the resolution of the retinal detachment such as in this particular case suggested possibility of early treatment failure.

Retinal detachment is one of the common complications of pathological myopia due to presence of retinal break. However, retinal break commonly occurs in the peripheral retina. This case report illustrates the rare incidence of retinal break adjacent to the optic disc, highlights the possible causes of poor visual outcome following surgical repair as well as the possible measures to treat the complications.

The study was carried out on children aged under 15 (male 64.44% and female 35.56%) suffering from endophthalmitis with 45 eyes. Three opening on the eye ball were made through pars plan area for inserting the water nail, the vitrectome and the ocular endoscope with the help of a coaxial surgical microscope and a lense, the target part of vitreous body was precisely located by the ocular endoscope. Pathological tissues of vitreous body was removed and replaced with ringer lactate solution. Antibiotics and Depersolon were injected into the pathologic eye ball to end the operation. 12 months after the surgery, among the operated eyes 12.83% showed clearly visible fondus, 15.38% slightly turbid, 7.69% reached a visual acuity of 0.4-0.7 and 17.95% of 0.1-0.3. Results showed that with the children suffering from endophthalmitis, this surgical treatment is an efficient approach.

Although there have recently been much advances in cataract surgery including cryoextraction, vitreous loss still remains as one of the major complications of cataract surgery and there is no completely effective method for its prevention and management. It is important to explain before surgery to the patient that such complications as vitreous loss and so on are occasionally inevitable. All methods which may be helpful to the prevention of vitreous loss should be undertaken before and during surgery. It is believed that vitreous aspiration with vitrectomy has been the preferred technique for the management of vitreous loss.

The results of diabetic vitrectomy on eyes with severe proliferative fibrovascular membranes are often disappointing, because of difficulties in removing the membranes. But we sometimes observe the regression of the proliferative fibrovascular membranes when the antero-posterior tractional force become released. Hence we compared the surgical prognosis of proliferative diabetic retmopathy according to the severity of proliferation and whether removal of antero-posterior vitreoretinal traction was complete or not. The results showed that the anatomic success rate and final visual acuities(VA) were significantly better in less-severe proliferation group(LSPG) than in severe prolif era tion group(SPG). In SPG, the anatomic success rate and VA tended to be better when we were able to remove the antero-posterior vitreoretinal adhesion completely whether the removal of preretinal membranes was complete or not. When complete removal of the diabetic fibrovascular membrane is difficult due to severe proliferation and broad adhesion, complete removal of anter-posterior traction only could be an alternative in diabetic vitrectomy.

Illumination and access of instruments to peripheral fundus are limited by lens in phakic vitrectomy. The purpose of this study was to determine if curved endoilluminator could enhance visibility of peripheral fundus in phakic virectomy. Ten consecutive cases of pars plana vitrectomy were done for vitreous opacity. Indirect laser photocoagluation was done to make four reference points of distance from optic disc to nasal ora serrata. We evaluated the respective extent of nasal peripheral view with the use of curved or straight endoilluminator which was inserted through temporal scleral port. When compared with the straight endoilluminator, the curved endoilluminator enhanced the visualization of peripheral fundus(p<0.05). A curved endoilluminator may be a useful surgical adjunct during the phakic vitrectomy and other advantages and disadvantages of its use are discussed.

PURPOSE: To describe a transconjunctival sutureless technique for pars plana vitrectomy using conventional 20-gauge instruments. METHODS: We performed transconjunctival sutureless pars plana vitrectomy (TSV) using conventional 20-gauge instruments in 36 eyes of 35 patients. We made 20-gauge transconjunctival beveled sclerotomies using microvitreoretinal (MVR) blades and used traditional 20-gauge instruments for the operations. RESULTS: Eighty-three (81.4%) of 102 sclerotomies self-sealed without the need for sutures. The sutureless rate was even higher in the last one-third of the patients: 32 (94.1%) of 34 sclerotomy sites were sutureless. No serious complications were observed in our series, including postoperative hypotony, wound leakage, or endophthalmitis. CONCLUSIONS: The 20-gauge TSV technique is safe and can be utilized for almost all vitreoretinal diseases, without incurring additional cost for new instruments.

To find out the optimal temperature of infusion fluid during vitrectomy, five rabbit eyes were infused with body temperature (37C) Balanced Salt Solution Plus (BSS Plus, Alcon Laboratories) and the other five eyes with room temperature (22C) BSS Plus. We recorded the ERGs before operation and 2 days, 7 days and 28 days after operation and each recording was plotted on paper with automatically measured amplitude. The a-wave amplitude, b-wave amplitude and b/a ratio showed no significant difference between 22C and 37C groups before operation and 2 days, 7 days and 28 days after operation. The a-wave amplitudes were decreased, b/a ratios were increased and b-wave amplitudes was not changed after operation in both 22C and 37C group. We suggest that there is no difference in the effects of infusion fluid to retinal function whether we use room temperature or body temperature infusion fluid.
