RESUMEN
A 63-year-old female with a history of retinal detachment repair with scleral buckle from 28 years prior presented with exposure of the buckle in her right eye. After removing the buckle and anchoring sutures, the operation field was washed with 0.25% polyvinyl alcohol-iodine, vancomycin, and ceftazidime. Cultures revealed Mycobacterium chelonae. Systemic meropenem was discontinued on postoperative day 5. The retina remained attached, and there was no recurrence over a 1-year follow-up. We report a case of NTM buckle infection that responded well to thorough washings with polyvinyl alcohol-iodine and antibiotic solutions instead of using a prolonged course of systemic antibiotics.
RESUMEN
PURPOSE: To report the clinical course of a sub-tenon injection of triamcinolone acetonide for treatment of an asymptomatic choroidal mass in sarcoidosis. METHODS: This was a retrospective, non-comparative interventional case study. RESULTS: A 36-year-old Japanese man with sarcoidosis presented with an asymptomatic choroidal mass lesion associated with subretinal fluid accumulation in his left eye, but without any other sign of intraocular inflammation in either of his eyes. He had started systemic steroid administration for thrombocytopenia 2 days prior to being examined. After a single sub-tenon injection of triamcinolone acetonide (20 mg) the subretinal fluid was completely absorbed and the choroidal granuloma began to shrink in size. After the injection, the granuloma became a scar without any complication or recurrence over the next 34 months. CONCLUSION: Sub-tenon injection of triamcinolone acetonide might be an effective treatment for choroidal granuloma in sarcoidosis.
RESUMEN
A 49-year-old male with untreated diabetes mellitus type 2 experienced eyesight deterioration and general malaise, and was treated for uveitis and orbital cellulitis. Later, he was taken to a local hospital via ambulance for a consciousness disorder and was diagnosed with bilateral infectious endophthalmitis, a right ureteral stone, and emphysematous pyelonephritis. He was then referred to our hospital for further examination and treatment. We immediately initiated intravenous antibiotic therapy with meropenem and glycemic control with continuous subcutaneous insulin infusion, and placed a ureteral and percutaneous drain tube into the right ureter and the emphysema, respectively. We performed a diagnostic and therapeutic vitrectomy on the patient's left eye. Urinary, blood, and vitreous cultures were positive for Klebsiella aerogenes. Abdominal contrast-enhanced computed tomography showed bilaterally comparable renal contrast enhancement. On the 60th hospital day, we performed endoscopic combined intrarenal surgery (ECIRS) and completely removed the urinary stone. Although he lost light sensitivity in his right eye, his left eyesight improved, and his blood glucose level was adequately managed by oral medication. Three months after the surgery, he was discharged from our hospital and he showed no sign of recurrence of the infection at ten months after surgery.

PURPOSE: To introduce a new three-dimensional (3D) endoscope system for vitrectomy. SUBJECTS AND METHODS: We report a single-center, retrospective, consecutive surgical case series of 391 eyes that underwent 25G hybrid vitrectomy. To create 3D endoscopic images, a 3D converter HD-3D-A was connected to a monocular endoscopic system. RESULTS: The 3D endoscope system was successfully used to perform hybrid vitrectomy. No intra- or postoperative complications related to this system were encountered in any of the cases. CONCLUSION: This 3D endoscope system appears to be a valuable and promising tool for use in vitrectomy.
RESUMEN
PURPOSE: To assess the updated chandelier illumination-assisted scleral buckle procedures using a 3D visualization system. SUBJECTS AND METHODS: We report a single-center, retrospective, consecutive surgical case series of 18 eyes of 16 patients that underwent scleral buckle procedures combining the use of chandelier endoillumination, a noncontact wide-angle viewing system, an anti-drying contact lens, and a recently developed 3D visualization system. The mean age of the patients was 30.2 years, and the mean follow-up time was 11.3 months. RESULTS: Retinal reattachment was achieved after the first surgery in all cases. There were no cases that required conversion of the 3D visualization to a conventional microscopic view. This updated chandelier-assisted scleral buckle procedure was successfully performed without any intraoperative or postoperative complications, except for the occurrence of postoperative diplopia in one case in which a supplementary radial buckle was used for a deep tear. CONCLUSION: The updated chandelier illumination-assisted scleral buckling surgery using a 3D visualization system appears to be a valuable and promising method for managing rhegmatogenous retinal detachment due to atrophic holes in lattice degeneration or ciliary tears in younger cases.
RESUMEN
PURPOSE: To introduce a hybrid wide-angle viewing-endoscopic vitrectomy, which we have reported, using a 3D visualization system developed recently. SUBJECTS AND METHODS: We report a single center, retrospective, consecutive surgical case series of 113 eyes that underwent 25 G vitrectomy (rhegmatogenous retinal detachment or proliferative vitreoretinopathy, 49 eyes; epiretinal membrane, 18 eyes; proliferative diabetic retinopathy, 17 eyes; vitreous opacity or vitreous hemorrhage, 11 eyes; macular hole, 11 eyes; vitreomacular traction syndrome, 4 eyes; and luxation of intraocular lens, 3 eyes). RESULTS: This system was successfully used to perform hybrid vitrectomy in the difficult cases, such as proliferative vitreoretinopathy and proliferative diabetic retinopathy. CONCLUSION: Hybrid wide-angle viewing-endoscopic vitrectomy using a 3D visualization system appears to be a valuable and promising method for managing various types of vitreo-retinal disease.
RESUMEN
PURPOSE: To report 4 cases undergoing 25-gauge endoscopic vitrectomy for the treatment of proliferative vitreoretinopathy with severe corneal opacity in which a transpupillary view of the fundus was not possible. STUDY DESIGN: A retrospective interventional case series. METHODS: The main outcomes measured were postoperative anatomic status of the retina and subjective improvement of vision. RESULTS: Postoperative reattachment of the retina and subjective improvement of vision were achieved in all 4 eyes. CONCLUSION: Twenty five-gauge endoscopic vitrectomy provides a clear view making it possible conduct pars plana vitrectomy in order to reattach the retina in cases of proliferative vitreoretinopathy with severe corneal opacity.

Drying of the cornea during surgery, which causes poor visibility of the fundus, is one of the most serious problems when using a noncontact-type wide-angle viewing system. This study used a newly commercialized lens for observing the fundus with a noncontact wide-angle viewing system. The lens used has a very thin meniscus made of polymethyl methacrylate and a large outer diameter. Following the application of viscoelastic material, the lens can be put on the cornea without using a contact lens fixation ring. The larger diameter and lightweight characteristics of the new lens contributed to the overall stabilization. The smooth surface of this lens was able to achieve an intraoperative view of good quality not only during vitrectomy but also during scleral buckling procedures.
RESUMEN
OBJECTIVES: Behçet's disease (BD) is a systemic inflammatory disorder polarised to the Th1 and Th17 immune systems. Allergic diseases are polarised to the Th2 immune system. The aim of the present study is to investigate the prevalence of allergic diseases in patients who have BD. METHODS: The study involved a large-scale interview survey of Japanese patients with BD at 21 institutes of ophthalmology; 353 patients (255 males and 98 females) were recruited for this study. We analysed the history of allergic diseases such as atopic dermatitis (AD), allergic rhinitis (AR), bronchial asthma (BA) and drug/food allergies (FA). RESULTS: Oral aphthous ulcers, ocular lesions, skin lesions, genital ulcers, arthritis, neurological lesions, intestinal lesions, deep vein thrombosis and epididymitis were reported in 95.8%, 98.6%, 72.5%, 44.8%, 13.9%, 6.8%, 6.2%, 3.7% and 1.4% of the patients, respectively. It was also reported that 73 patients (20.7%) had histories of allergic diseases: AD (5 cases, 1.4%), AR (36 cases, 10.2%), BA (19 cases, 5.4%) and FA (30 cases, 8.5%). This percentage was significantly lower than in a survey that Japan's Ministry of Health, Labour and Welfare conducted for healthy population (47.6%) (odds ratio = 0.29, 95% confidence interval = 0.22-0.38, p=4.9×10-22). Frequencies of posterior/pan-uveitis, relatively severe ocular findings, and visual prognosis were not affected by a history of allergic diseases in BD. CONCLUSIONS: Patients with BD had fewer complications from allergic diseases than did the entire population of Japan.

PURPOSE: To compare the effect of photodynamic therapy (PDT) and intravitreal ranibizumab in patients with polypoidal choroidal vasculopathy (PCV). DESIGN: Randomized clinical trial. SETTING: Multicenter. STUDY POPULATION: Total of 93 patients with treatment-naïve PCV. INTERVENTION: Patients were randomized to 2 arms. Patients in the PDT arm underwent a single session of PDT with verteporfin, and patients in the ranibizumab arm received 3 monthly ranibizumab injections at baseline. Additional treatment was performed as needed in each arm. MAIN OUTCOME MEASURES: Primary outcome measurement was the proportion of patients gaining or losing more than 0.2 logarithm of minimal angle of resolution (logMAR) units from baseline. Mean change of logMAR and central retinal thickness (CRT) were also evaluated. RESULTS: In the PDT arm (n = 47), 17.0% achieved visual acuity gain, 55.3% had no change, and 27.7% experienced visual acuity loss. The results were 30.4%, 60.9%, and 8.7%, respectively, in the ranibizumab arm (n = 46), significantly better than the PDT arm (P = .039). In the PDT arm, mean CRT improved (366.8 ± 113.6 µm to 289.1 ± 202.3 µm, P < .001), but logMAR was unchanged (0.57 ± 0.31 to 0.62 ± 0.40). The ranibizumab arm demonstrated improvement in both CRT (418.9 ± 168.6 µm to 311.2 ± 146.9 µm, P < .001) and logMAR (0.48 ± 0.27 to 0.39 ± 0.26, P = .003). Mean change of logMAR was also greater in the ranibizumab arm (P = .011). CONCLUSION: Intravitreal injection of ranibizumab is more effective than PDT for treatment-naïve PCV.

RESUMEN
PURPOSE: To evaluate the long-term effects of photodynamic therapy (PDT) on typical neovascular age-related macular degeneration (tAMD) and polypoidal choroidal vasculopathy (PCV). METHODS: This was a multicenter prospective study of 139 eyes from 136 patients (tAMD: 74 eyes; PCV: 65 eyes) who underwent PDT as the initial treatment. The change in best-corrected visual acuity (BCVA), predictive factors for the BCVA at 60 months, frequency of recurrence, and mean recurrence period were analyzed. RESULTS: The pre-PDT BCVA and greatest linear dimension (GLD) did not differ between the two groups. The mean BCVA (logMAR) was significantly improved at 6 months post-initial PDT (post-PDT) in the PCV group (-0.11, P = 0.0091). However, at 60 months post-PDT, the mean BCVA was significantly worse than baseline in the tAMD (+0.21, P = 0.0035) and PCV (+0.21, P = 0.0076) groups. Pre-PDT BCVA, age, and GLD were the factors significantly associated with the BCVA at 60 months post-PDT. Although the frequency of recurrence did not significantly differ between the two phenotype groups, the mean recurrence period was significantly longer in the PCV group than in the tAMD group (15.7 vs. 8.6 months, P = 0.0020). CONCLUSIONS: PDT may not have benefits for visual acuity in cases of tAMD and PCV over 5 years of follow-up.

Drying of the cornea during surgery, which causes poor visibility of the fundus, is one of the more serious problems when using a noncontact type wide-angle viewing system. We developed an antidrying corneal contact lens for use with this type of viewing system. The lens has a very thin meniscus made of polymethyl methacrylate with a large outer diameter. Following application of the viscoelastic material, the lens can be put on the cornea without using a contact lens fixation ring. The larger diameter and lightweight characteristics of our lens contributed to its overall stability. The smooth surface of this prototype lens was able to achieve an intraoperative view of good quality, not only by preventing the cornea from drying, but also by providing a smooth surface over the entire cornea.
RESUMEN
Endogenous endophthalmitis may be a rare condition in acute meningo-encephalitis. A 69-year-old compromised adult abruptly developed septic bacteremia and meningo-encephalitis by Klebsiella pneumoniae. After an improvement from initial conscious disturbance and systemic inflammatory unstable vital conditions by treatment of intensive antibiotic medications, severe unilateral endogenous endophthalmitis with impaired visual acuity was diagnosed by detailed ophthalmological assessments and it deteriorated rapidly. After early vitreous surgery with anti-biotic direct injection, the patient successfully regained visual acuity of 20/200. Among the organisms of endogenous bacterial endophthalmitis, Klebsiella pneumoniae is the worst pathogen mostly resulting in vision loss or enucleation despite any aggressive treatments. The neuro-physicians should recognize the presence of refractory endophthalmitis by Klebsiella pneumoniae, even if clinically asymptomatic, because prompt ophthalmologic diagnosis and managements may improve the outcome.

BACKGROUND: We report a case of an endoscope-assisted vitrectomy for the treatment of retinal detachment associated with microcornea in a normal size globe. SUBJECTS: A 26-year-old Japanese man was referred after complaining of visual acuity loss OD. Both eyes became aphakic because of surgery for congenital cataracts in infancy. The visual acuity was 0.02 OD. The corneal diameter was 7.5 × 7.0 mm and axial length was 23.89 mm. Retinal detachment was suspected, although the details were obscure because of nystagmus and small pupils. Endoscope-assisted, 23-gauge pars plana vitrectomy and encircling buckling were performed, and reattachment of the retina was achieved. OBSERVATIONS: Retinal breaks were identified, and peripheral parts of the retina were observed by endoscopy. CONCLUSIONS: Endoscope-assisted vitrectomy may be advantageous for the management of detachment in an eye with microcornea.

BACKGROUND: The purpose of this work was to compare the efficacy of photodynamic therapy (PDT) with or without posterior subtenon injections of triamcinolone acetonide (STA) or intravitreal injections of ranibizumab (IVR) for retinal angiomatous proliferation (RAP). METHODS: Thirty-seven eyes from 33 consecutive patients with RAP were treated by PDT monotherapy (Group 1), PDT combined with STA (Group 2), or PDT combined with IVR (Group 3). The best-corrected visual acuity, greatest linear dimension, central retinal thickness, and number of treatments were compared among the three groups. RESULTS: The change in mean best-corrected visual acuity (logMAR) at month 3, 6, and 12 after the initial treatment was better in Group 2 (-0.13, -0.23, and -0.21, respectively) and Group 3 (-0.018, 0.0028, and -0.0067, respectively) than in Group 1 (0.13, 0.19, and 0.23, respectively); Group 1 versus Group 2 was statistically significant (P = 0.018). The mean central retinal thickness was reduced from baseline in all groups, but the reduction amplitude was significantly greater in Group 2 than in Group 1 and Group 3. The mean number of treatments was significantly lower in Group 2 (1.1 ± 0.4) and Group 3 (1.5 ± 0.5) than in Group 1 (2.9 ± 0.9) in the 12 months after the initial treatment. CONCLUSION: Treatment with STA + PDT may be an effective therapy for RAP lesions over 12 months of follow-up.
RESUMEN
PURPOSE: This paper reports a young patient with a traumatic rhegmatogenous retinal detachment and massive vitreous gel incarceration into the subretinal space, who was successfully treated with 23-gauge transconjunctival vitrectomy. CASE REPORT: An 11-year-old boy was referred to the authors' clinic with traumatic retinal detachment in the right eye, 2 weeks after ocular contusion in a baseball accident. At the time of the injury, emergency fundus examination by his local doctor had revealed vitreous hemorrhage in the inferior quadrant of the right eye. Visual acuity was 1.5. He had continued to play baseball as usual for 2 weeks after the injury. At his first visit to the authors' clinic, fundus examination showed a highly bullous retinal detachment involving the inferior two quadrants, associated with multiple irregular retinal breaks. There was an oval hole in the inferior quadrant which was 10-disc diameter × 5-disc diameter in size and was surrounded by edematous and hemorrhagic retina. The macula remained attached. Absolute rest for 4 hours in the supine position with binocular occlusion did not diminish the height of the retinal detachment. A 23-gauge three-port pars plana vitrectomy combined with 360° circumferential buckling was performed under general anesthesia. The lens was retained. Incarceration of massive vitreous gel, including vitreous hemorrhage into the subretinal space through the largest break, was observed during vitrectomy. Reattachment of the retina was achieved by fluid-air exchange and internal tamponade using SF(6) gas. At follow-up at 9 months, the retina remained attached and visual acuity in the right eye was 1.2.
RESUMEN
PURPOSE: To demonstrate the efficacy of endoscope-assisted pars plana vitrectomy in treating patients with retinal detachments with no retinal breaks detected preoperatively. METHODS: Medical records of 20 consecutive eyes with pseudophakic and aphakic rhegmatogenous retinal detachments but without retinal breaks detected preoperatively were reviewed. In each case, endoscope-assisted pars plana vitrectomy was performed. RESULTS: In 19 of 20 eyes, breaks were identified with the help of an endoscope during surgery. To treat breaks, transscleral cryopexy or endolaser was performed under the endoscopic vision. The retina was reattached after a single surgery in all cases. No serious complication related to the operation was experienced. CONCLUSION: Endoscope-assisted vitrectomy is useful in the management of pseudophakic and aphakic retinal detachments with undetected retinal breaks preoperatively.

PURPOSE: To evaluate the geographic pattern of central retinal sensitivity and its resolution shortly after intravitreal injection of triamcinolone acetonide (IVTA) for diabetic macular edema (DME). METHODS: Twenty eyes of 20 patients who underwent IVTA for the treatment of DME were reviewed retrospectively. Early changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), photoreceptor inner and outer segments (IS/OS) line and central retinal sensitivity were analyzed. Retinal sensitivity was measured at 40 points within the central 10 degrees of the macula with the Micro Perimeter 1 before treatment, and at 1 week and 1 month after IVTA. RESULTS: Mean BCVA and CMT improved significantly at 1 week and 1 month after IVTA. Mean retinal sensitivity, however, showed no significant improvement at 1 week (P = 0.238), but did show significant improvement at 1 month (P = 0.0003). Mean retinal sensitivity of the points at the central 2 degrees, which was significantly lower than that at 6 and 10 degrees before treatment, showed improvement similar to those of 6 and 10 degrees after IVTA. Mean retinal sensitivity in the nasal quadrant of the macular area had the best sensitivity at all time points, and improved more than it did in the other quadrants. Mean retinal sensitivity in the central 2 degrees was better in the eyes with complete IS/OS line (P < 0.0001). CONCLUSIONS: BCVA and CMT improved significantly after IVTA for DME. Retinal sensitivity also showed significant, albeit relatively slow, improvement. The nasal quadrant of the macular area showed more improvement than did any other quadrant.
