Purpose: To report clinical and optical coherence tomography (OCT) features in patients with idiopathicmacular hole and extensive subretinal fluid (extending at least 1 disk diameter from the center of the hole). Design: Retrospective, consecutive, noncomparative case series. Methods: The case records of two patients with idiopathic macular holes with extensive subretinal fluid were reviewed. Results: Both patients presented with reduced visual acuity (20/200 and 20/400). OCT demonstrated attachment of the posterior hyaloid to the inner retina, a fullthickness macular hole, cystoid macular edema (CME), and extensive subretinal fluid. After surgery, both patients achieved macular hole closure and improvement in visual acuity (20/60 and 20/30). Postoperatively, OCT sh.w.d a normal foveal contour, complete hole closure, and resolution of the CME and subretinal fluid. Conclusions: In patients with macular hole and extensive subretinal fluid, improved visual acuity and hole closure can be achieved. Preoperative OCT in these patients demonstrates vitreoretinal interface abnormalities, CME, and extensive subretinal fluid. These changes resolve postoperatively.

Purpose To report pseudohypopyon after intravitreal triamcinolone acetonide in jection for cystoid macular edema. Design Retrospective, noncomparative, consecu tive case series. Methods Records were reviewed of all patients who developed ps eudohypopyon after intravitreal triamcinolone acetonide injection at Bascom Palm er Eye Institute between January 1, 2002 and February 1, 2004. Results A total o f 828 intravitreal triamcinolone acetonide injections were administered to 686 p atients during the study period. A pseudohypopyon (fine white crystalline opacit ies in the inferior anterior chamber angle) and suspended white crystalline opac ities in the aqueous humor developed after 7 of the 828 injections (0.8%); all pseudohypopyons occurred within 3 days of injection and resolved completely with in 2 weeks. None of the 686 patients developed clinically suspected infectious e ndophthalmitis. Conclusions A transient pseudohypopyon may occur in the early po stinjection period after intravitreal triamcinolone acetonide injection. Unless progressive intraocular inflammation occurs, close observational management is i ndicated.

To investigate the clinical settings, management strategies, antibiotic sensit ivities, and visual acuity outcomes for eyes with endophthalmitis caused by haem ophilus influenzae. Retrospective, noncomparative, consecutive case series. The medical records were reviewed of all patients treated for culture proven h. inf luenzae endophthalmitis at a single institution between January 1, 1980, and Dec ember 31, 2002. Visual acuity and antibiotic sensitivities. The study included 1 6 eyes of 16 patients with a median age of 68 years (range, 6 months-83 years) and a median follow up of 26 months (range, 2 months-15 years). Clinical setti ngs included post trabeculectomy (n=7), postcataract surgery (n=6), post pars plana vitrectomy (n=1), post secondary intraocular lens insertion (n=1), and po stsuture removal from an extracapsular cataract wound (n=1). Eleven (69%) cases were of delayed onset ( > 6 weeks from surgery/event), with a median interval b etween surgery/event and presentation with endophthalmitis of 18 months (range, 44 days-21 years); 5 (31%) cases were of acute onset (median, 6 days; range, 2 -14 days). Presenting visual acuity was hand movements or better in 7 (44%) ey es. A vitreous tap and inject was performed initially in 9 (56%) eyes, and a vi trectomy was performed initially in the remaining 7 (44%) eyes. All eyes receiv ed intravitreal antibiotics on the day of presentation, and 11 (69%) received i ntravitreal dexamethasone. In vitro testing of the h. influenzae isolates reveal ed that 14 of 16 (88%) were sensitive to vancomycin, ampicillin, and trimethopr im/sulfa methoxazole; 15 of 16 (94%) were sensitive to aminoglycosides (1 isol a te was resistant to gentamicin); and all were sensitive to cephalosporins, fluor oquinolones, and carbapenems. The organisms were sensitive to at least 1 of the initial antibiotics administered in all cases. Final visual acuity was 5/200 or better in 6 (38%) eyes, and 6 (38%) eyes had a final visual acuity of no light pe

黄斑裂孔成功修补后持续性外侧视网膜缺损

To report two cases of a persistent outer retinal defect evident by optical coherence tomography (OCT) after clinically successful macular hole surgery. Retrospective case series. A retrospective case series of two patients who had a persistent outer retinal defect by OCT and excellent visual acuity after clinically successful macular hole surgery. Two patients with stage 2 macular holes and preoperative visual acuity of 20/70 and 20/60, respectively, underwent macular hole surgery. Although the macular holes were closed on clinical evaluation, a persistent outer retinal defect was identified by OCT in both patients. At 5 to 6 months postoperatively, the outer retinal defect became less prominent and the visual acuity remained at 20/20 in both patients. An outer retinal defect by OCT may occur in the early postoperative period after macular hole surgery. Despite this defect, good visual acuity is possible.

BACKGROUND AND OBJECTIVE: To compare outcomes of macular hole surgery using silicone oil with C3F8 gas tamponade. PATIENTS AND METhODS: A retrospective case-control study of patients who underwent macular hole surgery for stage 2, 3, or 4 macular holes. RESULTS: Forty-six eyes of 44 patients underwent macular hole surgery involving injection of silicone oil (23 cases) or gas tamponade (23 controls). Anatomic closure occurred in 19 (82.6%) cases and 20 (86.9%) controls. Visual acuity improved to 20/70 or better in 4 (17.3%) of the cases and in 17 (73%) of the controls. CONCLUSION: In the current study of macular hole surgery, outcomes were better among patients with gas tamponade.

Background: The Slender-billed Parakeet(Enicognathus leptorhynchus) is a psittacine endemic to southern Chile and an obligate secondary cavity-nester. In the central valley of southern Chile, most(94%) of the known Slender-billed Parakeet nests have occurred in large, mature southern beech(Lophozonia obliqua) trees(locally known as "pellines"). As relicts of the original old-growth forests of southern Chile, most pellines have been lost due to extensive landclearing throughout the region, potentially threatening long-term persistence of the Slender-billed ***: we conducted our study in the central valley of southern Chile, near the city of Osorno during three consecutive nesting seasons(November–January, 2008–2011). Nest trees used by Slender-billed Parakeets were located by direct observation of parakeet activities and through interviews with local residents, some of whom were former parrot nest poachers. Nest cavities were accessed, inspected and measured using single-rope climbing techniques. we report means, standard errors, 95% confidence intervals and ranges for 11 cavity-related variables. we also report clutch sizes encountered in active nests, and age estimates of nest trees based on known growth rates of Lophozonia trees in southern Chile. Linear regressions were used to evaluate potential relationships between cavity-related variables and clutch ***: we located and measured 38 Lophozonia tree cavities used for nesting by Slender-billed Parakeets. Compared to those used by other psittacines, nest trees were relatively large, averaging 30.4 breast height of 134.5 ter ± 1.1 m in height with a mean diameter at ± 4.7 cm. Based on estimated annual diameincrement, ages of nest trees ranged from approximately 209–485 years. Nest cavities entrances averaged 12.5 ± 0.9 m in height above ground level. Cavity entrance widths averaged 51.0 ± 13.3 cm(vertical) by 11.5 ± 0.7 cm(horizontal). Cavity entrance orientations were apparently random, with

This paper is devoted to the study of a nonlinear evolution eddy current model of the type δtB（h）＋ △↓× （ △↓ × h） =0 subject to homogeneous Dirichlet boundary conditions h × v = 0 and a given initial datum. here, the magnetic properties of a soft ferromagnet are linked by a nonlinear material law described by B（h）. we apply the backward Euler method for the time discretization and we derive the error estimates in suitable function spaces. The results depend on the nonlinearity of B（h）.

In this short note we revisit the convex integration approach to constructing very weak solutions to the 2D Monge-Ampére equation with h?lder-continuous ?rst derivatives of exponent β h is based on combining the approach of Lewicka and Pakzad(2017) with a new diagonalization procedure which avoids the use of conformal coordinates, which.w.s introduced by De Lellis et al.(2018) for the isometric immersion problem.
