Efficacy of Intravitreal Injection of Filtered Modified Low-Dose Triamcinolone Acetonide and Ranibizumab on Pseudophakic Cystoid Macular Edema.

PurposeTo compare the visual and morphological effects between intravitreal injection of filtered modified 2 mg triamcinolone acetonide (TA) and 0. 5 mg ranibizumab in patients with pseudophakic cystoid macular edema (PCME).MethodsA retrospective, interventional study was conducted from January 2015 to February 2020 involving patients with PCME after uneventful cataract surgery. A total of 25 patients (25 eyes) with PCME received an intravitreal injection of 0.22 μm filtered modified 2 mg TA, while 15 patients (15 eyes) received 0.5 mg ranibizumab injection. Central macular thickness (CMT), best-corrected visual acuity (BCVA), intraocular pressure (IOP), times of repeated injections, and other side effects were observed at 2 weeks, 1 month, 3 months, and 6 months after injection; then, the data were compared with preinjection information in each group and between the two groups.ResultsBoth the TA and ranibizumab intravitreal injection can achieve improved BCVA and reduced CMT in patients with PCME (P < 0.05), with a trend toward greater improvement in the TA group, but the difference was only significant at 3 months (P < 0.05). IOP was in the normal range without any significant difference (P > 0.05). Thirty-three percent of patients in the ranibizumab group required repeated intravitreal injection compared to 4% in the TA group. Further stratified analysis showed that the better therapeutic effect of the TA group at 3 months after injection only existed in patients with diabetes mellitus (DM), while not in patients without DM. There was no repeat injection in the TA group and 12.5% in the ranibizumab group for patients without DM, while 16.7% in the TA group and 57.1% in the ranibizumab group required repeated injection for patients with DM, which had a significant difference (P < 0.05).ConclusionIntravitreal injection of filtered modified 2 mg TA is safe, effective, and an inexpensive alternative to antivascular endothelial growth factor (anti-VEGF) agents for patients with PCME, especially for patients concurrently with DM. A large number of clinical randomized controlled studies along with long-term follow-up observations are needed.

Refractive Outcomes of Uneventful Cataract Surgery in Pseudoexfoliation Syndrome and Pseudoexfoliation Glaucoma.

PurposeTo compare the refractive outcomes after cataract surgery between patients with and without pseudoexfoliation, and to evaluate the risk factors of refractive error.MethodsRetrospective review of 210 eyes with pseudoexfoliation (study group) and 510 normal eyes (control group) that underwent uneventful phacoemulsification with intraocular lens implantation. The study group included pseudoexfoliation syndrome and pseudoexfoliation glaucoma (PXG) subgroups. The main outcome measure was refractive error, defined as the difference between the target refraction and postoperative refraction in diopter (D). A refractive error >±1.0 D was identified as a large-magnitude refractive error. The frequency of the large-magnitude refractive error was compared between study and control groups, and also between each subgroup and normal eyes. The factors influencing refractive error were analyzed by logistic regression.ResultsThere was a significantly higher frequency of a refractive error >± 1.0 D and hyperopic error >1.0 D in the study group than in the control group (p = 0.001 and p = 0.003, respectively). In the multivariate logistic regression analysis, PXG and poor preoperative visual acuity were related with a large-magnitude refractive error (p = 0.001 and p = 0.02, respectively) Refractive error >± 1.0 D and hyperopic error >1.0 D were noted more often in PXG eyes that had an intraocular pressure spike >25 mmHg at postoperative first 24 hours (p = 0.01 and p=0.03, respectively).ConclusionsThe eyes with pseudoexfoliation were at a high risk for refractive error, especially in the presence of glaucoma. In PXG, the only significant risk factor for refractive error was observed to be the presence of an intraocular pressure spike.

Incidence of postoperative week 1 management changes after resident-performed phacoemulsification cataract surgery

BackgroundThe goal of this study was to investigate the incidence of departures from routine care at the postoperative week 1 (POW1) visit following uneventful resident-performed cataract surgery in asymptomatic patients who had a normal postoperative day 1 (POD1) examination.MethodsA retrospective chart review of phacoemulsification surgeries performed by the senior resident class at Montefiore Medical Center between June 20, 2018 and April 1, 2019 was performed. The most recent preoperative visit note, operative report, POD1 visit note, and POW1 visit note were evaluated and variables were recorded. Exclusion criteria consisted of any complications that would have necessitated close follow-up and a POW1 visit, whether discovered preoperatively, intraoperatively, at the POD1 visit, or leading up to the POW1 visit. The primary outcome measure was the incidence of unanticipated management changes at the POW1 visit following resident-performed cataract surgery.ResultsThe charts of 292 surgical cases of 234 patients that underwent phacoemulsification with intraocular lens implantation were reviewed. 226 cases (77%) had an uncomplicated pseudophakic fellow-eye history, with a routine surgery, and POD1 examination. 19 of these patients had symptomatic presentations at the POW1 timepoint, and an additional 30 had no POW1 visit at all. In total, 177 cases were included in the study, and only 4 of these cases (2.3%) had an unexpected management change at the POW1 visit.ConclusionsAsymptomatic patients who underwent uncomplicated cataract surgeries performed by resident surgeons followed by a routine POD1 visit had a low incidence of unexpected management changes at the POW1 visit. These results suggest that regularly scheduled POW1 visits could potentially be omitted for patients deemed to be at low risk for complications, and instead performed on an as-needed basis.

Accuracy of Barrett versus third-generation intraocular lens formula across all axial lengths

The purpose of this study is to evaluate and compare the accuracy of Barrett Universal II versus third-generation formula for different intraocular lens (IOL) powers for Indian eyes with different axial lengths (ALs). This is a retrospective, nonrandomized consecutive case series. This study reviewed 981 eyes from 825 patients who had uneventful cataract surgery and IOL implantation. The eyes were separated into subgroups based on AL as follows: short (<22.0 mm), medium (22.01-23.99 mm), and long (>24.0 mm). The predicted refractive outcome using formulas was calculated and compared with the actual refractive outcome to give the prediction error. The percentage of every refractive error absolute value for each formula was calculated at <±0.50D, 0.50D-0.75D, and >±0.75D. In all, 981 eyes were analyzed. There were no significant differences in the median absolute error predicted by Barrett and the third-generation formulae. The Barrett Universal II formula resulted in significantly lowest mean spherical equivalent in short eyes (P = 0.0047) as well as a higher percentage of eyes with prediction errors within <±0.50D, 0.50D-0.75D, and >±0.75D. We found that the Barrett Universal II formula had the lowest predictive refraction error and mean absolute error across all ALs. The Barrett Universal II formula rendered the lowest predictive error compared with SRK/T, Holladay, and Hoffer Q formulas. Thus, the Barrett Universal II formula may be regarded as a more reliable formula for achieving emmetropia and reducing postoperative refractive surprises across all ALs.

Cefuroxime-Induced Toxic Maculopathy: A Cataract Co-Management Conundrum

Background: Cefuroxime-induced toxic maculopathy can occur when an incorrect dilution is injected intracamerally after cataract surgery. This results in a guarded visual prognosis. Cefuroxime-induced toxic maculopathy can also occur sporadically even when the medication dilution is the standard correct dosage. These patients usually recover their vision by the first postoperative week. Case Report: A 72-year-old Caucasian female developed cefuroxime-induced toxic maculopathy after uneventful cataract surgery. Investigation of the case confirmed that she had a sporadic response to the cefuroxime. It was verified that she received the standard correct dilution of cefuroxime intracamerally. The patient showed a significant improvement in her vision by her first postoperative weekly visit. By her last postoperative visit at 7 weeks her best corrected visual acuity was 20/20. Conclusion: Optometrists should be aware of cefuroxime-induced toxic maculopathy and distinguish between sporadic cases and those where the patient received an incorrect medication dilution dosage.

Evaluation of Quality of Vision and Visual Outcomes with Bilateral Implantation of a Non-Diffractive Extended Vision Intraocular Lens with a Target of Slight Myopia in the Non-Dominant Eye.

PurposeTo assess the visual outcomes and quality of vision of patients receiving the AcrySof® IQ Vivity™ non-diffractive extended vision intraocular lens (NDEV IOL) after uneventful cataract surgery when the non-dominant eye is targeted for slight myopia.DesignSingle site, prospective, single-arm study.MethodsEligible subjects interested in reducing their dependence on spectacles over a range of working distances were enrolled and followed for 3 months after the second eye surgery. Subjects were bilaterally implanted with this NDEV IOL, with a target of emmetropia in the dominant eye and a myopic refraction of −0.75D in the non-dominant eye. At 3 months postoperative, the uncorrected and distance-corrected (with monovision) visual acuity at 40 cm, 66 cm and 4 m were recorded, along with the manifest refraction. Questionnaires related to spectacle independence, patient satisfaction and quality of vision were also administered.ResultsData from 33 subjects were analyzed. The mean difference between eyes by subject was 0.80 ± 0.37 D. Twenty-nine of 33 (88%) subjects had a binocular uncorrected near VA of 0.2 logMAR or better. Twenty-five of 33 eyes (76%) had a binocular distance-corrected (−0.75 D in the non-dominant eye) VA of 0.2 logMAR or better at all three test distances. Satisfaction with vision at all distances was high. The reported level of spectacle independence was higher than for the same lens without monovision. Visual disturbances were higher than has been previously reported for this lens but were not correlated to the level of monovision.ConclusionA target of −0.75 D of myopia in the non-dominant eye of patients bilaterally implanted with this NDEV IOL improved near vision, increasing the rate of spectacle independence in patients relative to those targeted for bilateral emmetropia, with no correlated increases in visual disturbances.

A white daisy on intraocular lens

We report two patients with precipitation of Pseudo-exfoliative material (PXF) material on intraocular lens (IOL), a rare entity, years after uneventful cataract surgery. The PXF material was present on the anterior surface of the IOL optic in a characteristic radiating spoke-like manner, a pattern resembling shape of a white daisy flower. Emphasis is given on differentiating features between PXF deposition on natural lens and PXF deposition on IOL. Furthermore, how opacification of IOL is different from PXF on IOL is briefly explained. In the first case, PXF deposits were not found elsewhere except on anterior IOL surface and in the second patient, pupillary involvement was also noted along with settling on IOL optic. The fellow eyes in both the patients did not have PXF. PXF on IOL is a vital sign and should not be overlooked as it can be the only clue warranting thorough glaucoma evaluation.

Multimodal imaging of a choroidal macrovessel

AbstractPurposeTo describe the features of a choroidal macrovessel (CM) in multimodal imaging and underline the importance of non‐invasive imaging techniques.MethodsA 78‐year‐old man presented to our department for alteration of central vision of the right eye after uneventful cataract surgery. The patient had a complete ophthalmic examination with best corrected visual acuity (BCVA) measurement and slit lamp examination. Multimodal imaging was performed including fundus autofluorescence (FAF), Swept‐Source Optical Coherence Tomography (SS‐OCT), en‐face OCT, OCT‐angiography, Fluorescein Angiography (FA) and Indocyanine Angiography (ICG‐A).ResultsBCVA was 20/50 in the right eye and 20/80 in the left eye. Anterior segment examination was unremarkable except for a nuclear cataract in the left eye. Funduscopic examination showed a subretinal tortuous lesion starting in the fovea and extending toward the temporal periphery in the right eye and was normal in the left eye. FAF of the right eye showed increased autofluorescence of the lesion retracing its serpiginous shape. SS‐OCT revealed a choroidal hollowness. This lesion had a pattern corresponding to a choroidal macrovessel on en‐face OCT scans with a similar signal to the physiological choroidal vessels. OCT‐A showed a low signal within the choroidal vessel. FA of the right eye showed an early serpentine‐shaped hyperfluorescence and ICG‐A revealed early prominent filling with late hypofluorescence and persisting laminar flow. A choroidal macrovessel (CM) was diagnosed.ConclusionsCM is a rare entity that is not always easy to recognize. ICGA is the most valuable tool for its diagnosis when the presentation is not typical. In cases of CM with a well delineated pattern, non‐invasive imaging modalities and particularly SS‐OCT and en‐face OCT can be very helpful for the diagnosis while avoiding dye injection.

Lacteocrumenasia

Capsular bag distension syndrome (CBDS) is a rare complication of cataract surgery characterized by collection of turbid fluid between the posterior surface of the intraocular lens (IOL) and the posterior capsule. Here, we report a case of CBDS presenting 7 years after uneventful cataract surgery. Patient presented with blurring of vision in the right eye and his best corrected visual acuity (BCVA) was 6/9 N6. Slit lamp examination showed collection of turbid fluid between IOL and posterior capsule, and the opaque fibrosed capsulorhexis margin was adherent to the optic of IOL which was well placed within the bag. Patient underwent neodymium yttrium aluminium garnet (ND-YAG) laser posterior capsulotomy to release the fluid into the vitreous cavity. 6 weeks after the procedure his BCVA improved to 6/6 N6.

Comparative evaluation of macular thickness following uneventful phacoemulsification and small incision cataract surgery

Risk factors, complications, and outcomes of phacoemulsification cataract surgery complicated by retained lens fragments in Asian eyes: A 10-year retrospective study.

PURPOSE:To study the risk factors, visual outcomes, and sequelae of phacoemulsification surgery complicated by retained lens fragments (RLFs).METHODS:This single-center case–control study enrolled consecutive eyes complicated by RLF and compared them to age- and gender-matched uneventful cataract surgery cases at a tertiary care teaching hospital. Biometric, intraoperative, and postoperative data were collected. The primary outcome measures were risk factors, visual outcomes, and rate of postoperative complications.RESULTS:The study and control groups included 282 and 289 eyes, respectively. The estimated incidence of RLF was 1.47% during the study. We found a statistically higher risk of RLF among diabetics (P < 0.001), those with a history of intravitreal injections (P = 0.001), eyes with dense nuclear sclerosis, anterior capsular cataract (P < 0.001), and posterior polar cataract (P = 0.01). There was a statistically higher risk of RLF in eyes with a higher mean preoperative visual acuity (logarithm of the minimum angle of resolution) (P < 0.001) and in cases performed by trainees (P < 0.001). Most eyes in the RLF group (n = 207, 73.4%) retained their preoperative vision or experienced a one-line improvement in visual acuity and 14 eyes (5.3%) experienced more than one-line improvement in vision.CONCLUSION:Although RLFs are rare, they can affect the quality of postoperative vision and outcomes of complicated phacoemulsification surgery.

Neovascularisation of the lens capsule: a unique finding

A 62 year-old man consulted for progressive loss of vision in both eye. His past ophthalmological history was unremarkable and he denied any known systemic condition. On examination, his best corrected visual acuity was light perception oulus uterque (OU). Papillary reaction to light was sluggish oculus sinister (OS) and normal OU. Ocular motility was full OU with normal intra-ocular pressure. Slit-lamp examination showed bilateral white mature cataract with low pharmacological dilation. High magnification under dilation revealed a vascular network composed of fine vessels located nasally adjacent to the papillary border on the anterior capsule of the lens associated with pigment deposits and loss of the papillary frill (A). There was no evidence of neovascularisation of the iris (NVI) or the angle neurovascular assessment (NVA). Ocular ultrasound was negative for vitreous hemorrhage or retinal detachment. Ancilliary testing for diagnosis of common aetiologies of anterior segment neovascularisation was carried out and revealed type 2 diabetes. The patient was referred for evaluation and control of his newly diagnosed diabetes. After six months, we performed an uneventful cataract surgery by phacoemulsification. Fundus fluorescein angiography (FFA) showed posterior segment ischemia with neovascularisation elsewere (B). Neovascularisation spared the iris and the angle. Thus, nerve conduction velocity (NVC) was the solely sign of anterior segment neovascularisation.

Refractive prediction by various intraocular lens formulas using optical biometry and effect of ocular parameters on their accuracy

Purpose:To assess the prediction accuracy of intraocular lens (IOL) formulas and study the effect of axial length (AL), central corneal thickness (CCT), anterior chamber depth (ACD), and lens thickness (LT) on the accuracy of formulas using optic biometry.Methods:This study was performed on 164 eyes of 164 patients who underwent uneventful cataract surgery. Ocular biometry values were measured using Lenstar-900, and intraocular lens (IOL) power was calculated using the SRK/T, SRK II, Hoffer Q, Holladay 2, and Barrett Universal II formulas. We evaluated the extent of bias within each formula for different ocular biometric measurements and explored the relationship between the prediction error and the ocular parameters by using various IOL formulas.Results:The summarization of refractive prediction error and absolute prediction error for each IOL formulation was performed after adjusting the mean refractive error to zero. The deviation in the error values was minimum for SRK/T (0.265) followed by Holladay 2 (0.327) and Barret (0.382). Further, SRK/T had the lowest median (0.15) and mean (0.198) absolute error as compared to other formulations. For the above formulations, 100% of the eyes were in the diopter range of ±1.0. It was observed that the overall distribution of error was closer to zero for SRK/T, followed by Holladay 2 and then Barrett.Conclusion:In summary, we found that accuracy was better in SRK/T formula. We achieved a better understanding of how each variable in the formulas is relatively weighed and the influencing factors in the refraction prediction.

Structural Characteristics of the Lens in Presenile Cataract.

The purpose of this work is to examine the structure of the anterior lens epithelial cells (aLECs) of presenile idiopathic cortical cataract to investigate the possible structural reasons for its development. The anterior lens capsules (aLCs: basement membrane and associated lens epithelial cells) were obtained from routine uneventful cataract surgery of 5 presenile cataract patients (16 and 41 years old women and 29, 39, and 45 years old men). None of the patients had family history of cataract, medication, or trauma and they were otherwise healthy. In addition, the patients did not have any other abnormal features in the ocular status except cataract. The aLCs were prepared for scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The most prominent abnormal features observed by SEM for all 5 studied presenile cataract patients were the changes of the aLECs structure with the dents, the selective concavity of some LECs, at their apical side centrally toward the nucleus. In addition, TEM showed the thinning of the lens epithelium with the segmentally concave cells and the compressed and elongated nuclei. Abnormal and distinguishable structural features were observed in the anterior lens epithelium aLECs in all 5 patients with presenile cataract. Disturbed structure of aLECs, regularly present in presenile cataract type is shown that might be associated with water accumulation in the presenile idiopathic cortical cataract lens.

Intraoperative dexamethasone intravitreal implant in diabetic macular edema patients undergoing phacoemulsification: The CataDex study.

To assess the impact of preoperative intravitreal dexamethasone implant (DexI) on functional and anatomic outcomes in patients with diabetic macular edema (DME) who underwent phacoemulsification cataract surgery. Prospective and non-comparative study conducted on consecutive DME patients undergoing cataract surgery. DexI was administered 15 days before surgery and in a pro re nata regime after surgery. Main outcome measures were mean change in central retinal thickness (CRT), central subfield thickness (CST), total macular volume (TMV), and central subfield volume (CSV) from baseline to month-12. Secondary outcome was mean change in best corrected visual acuity (BCVA). Forty eyes were included in the study. CRT significantly decreased from 410.4 ± 64.8 µm at baseline to 303.2 ± 24.3 µm at month-12, p < 0.0001. Similarly, CST was significantly reduced from 436.4 ± 120.4 µm at baseline to 322.9 ± 54.2 µm at month-12, p < 0.0001. Total macular volume and CSV were significantly reduced from 9.95 ± 1.68 mm3 and 0.38 ± 0.11 mm3 at baseline to 8.49 ± 0.83 mm3 and 0.31 ± 0.05 mm3 at month-12, respectively (p < 0.0001 each, respectively). BCVA significantly improved from 0.26 ± 0.17 Snellen equivalent at baseline to 0.65 ± 0.19 at month-12, p < 0.0001. Mean DexI administered during the study were 2.0 ± 0.3. Neither DME subtype nor previous treatment status had any effect on functional or anatomic outcomes. Regarding safety, one (2.5%) eye developed ocular hypertension, which was successfully controlled with topical hypotensive treatment. DexI was and effective and safe strategy for managing DME in diabetic patients undergoing uneventful cataract surgery.

Intraocular lens power calculation in virgin eyes: Accuracy of the Barrett Universal II formula and a Ray tracing software.

To compare the accuracy of Sirius ray tracing software with the Barrett Universal II formula for intraocular lens power prediction in virgin eyes. Retrospective case series including 86 eyes that have undergone uneventful cataract surgery with SN60WF implantation. The median absolute error, mean prediction error, variance, and the percentage of eyes within ± 0.25 D, ± 0.50 D, ± 0.75 D, and ± 1.00 D of the prediction error in refraction were calculated. The correlation of prediction error with different baseline parameters was investigated. No differences were found between the median absolute error of the Barrett Universal II formula (0.226 D) and the ray tracing software with different intraocular lens centerings; apex (0.331 D), limbus (0.345 D), and pupil (0.342 D) (p = 0.084). The variance, from lowest to highest, was the Barrett Universal II (0.144 D2), ray tracing-limbus (0.285 D2), ray tracing-pupil (0.285 D2), and ray tracing-apex (0.287 D2) (p = 0.027). The Barrett Universal II formula showed a higher percentage of eyes within ± 0.25 D (56.98%), ± 0.50 D (82.56%), and ± 0.75 D (93.02%) compared to ray tracing software (p < 0.01). A significant correlation between the prediction error of the Barrett Universal II formula and corneal diameter (r = 0.322, p = 0.002) and pupil diameter (r = 0.230, p = 0.033) was found. Also, a positive correlation between the prediction error of Sirius ray tracing and axial length (p < 0.001) and pupil diameter (p = 0.01) was found. There is a trend of the Barrett Universal II formula to be more accurate than Sirius ray tracing software for intraocular lens power calculation in virgin eyes. This should be confirmed in future prospective comparative studies.

Anterior chamber depth variability between 2 hydrophobic acrylic 1-piece intraocular lenses: randomized trial.

To analyze the difference in anterior chamber depth (ACD) after uneventful cataract surgery between 2 hydrophobic acrylic 1-piece intraocular lenses (IOLs) with different material properties. Hanusch Hospital, Vienna, Austria. Single-center, bilateral randomized paired-eye controlled study. Patients scheduled for bilateral cataract surgery were randomized to receive the Clareon IOL in 1 eye and the AcrySof IQ IOL (both Alcon Laboratories, Inc.) in the contralateral eye. Preoperatively, a slitlamp examination, optical biometry (IOLMaster 700, Carl Zeiss Meditec AG), refraction, and visual acuity measurements were performed. ACD was assessed 1 hour and 1 week postoperatively and with additional measurement of uncorrected (UDVA) and corrected distance visual acuity (CDVA) 6 months postoperatively. 80 eyes of 40 patients were analyzed in this study. ACD at the 6-month follow-up was 3.94 ± 0.30 mm for the Clareon IOL and 3.91 ± 0.32 mm for the AcrySof IQ IOL (P = .08). Statistically significant differences in the ACD shift between both IOLs were detected between 1 week and 6 months (P = .04) and 1 hour and 6 months (P = .04). There were no statistically significant differences between both IOLs in UDVA (P = .78), CDVA (P = .59), and spherical equivalent (SE, P = .39) at the 6-month visit. The mean absolute error between the measured and the aimed SE was not significant (P = .97). There was no clinically relevant difference in ACD between the Clareon IOL and the AcrySof IQ IOL in patients after uneventful cataract surgery. Both IOLs yielded good refraction and visual acuity outcomes.

Accuracy of Newer Generation IOL Power Calculation Formulas in Eyes With High Axial Myopia.

To compare the accuracy of the Barrett Universal II, Emmetropia Verifying Optical (EVO), Haigis, Kane, and SRK/T formulas for intraocular lens power calculation in patients with high axial myopia. In this retrospective study, 175 eyes (175 patients) that underwent uneventful cataract surgery were enrolled. According to the axial length (AL), the eyes were divided into long AL (26 ⩽ AL < 28 mm), super long AL (28 ⩽ AL < 30 mm), and extremely long AL (⩾ 30 mm). The mean absolute prediction errors (MAE) 3 months postoperatively and the percentage of eyes within different prediction error were compared, followed by subgroup analysis. The MAE and percentage of eyes within ±0.50 diopters (D) of the five formulas were as follows: Barrett Universal II (0.342, 74.9%), EVO 2.0 (0.314, 82.3%), Haigis (0.336, 74.9%), Kane (0.318, 78.9%), and SRK/T (0.398, 69.7%) (P = .552 and .071, respectively). Although no significant difference was found among the five formulas in the super and extremely long AL groups (P = .792 and .227, respectively), the EVO 2.0 formula achieved the highest accuracy (88.9%, 72 of 81) in the long AL group (P = .049). Moreover, the accuracy of the EVO 2.0 and Haigis formulas was stable, regardless of AL. The SRK/T formula showed a negative trend in the long and super long AL groups, whereas the Barrett Universal II, Kane, and SRK/T formulas showed positive trends in the extremely long AL group. Overall, the EVO 2.0 and Kane formulas achieved better results in patients with high axial myopia, whereas the other three formulas showed slightly poor outcomes.

A Rare Case of Fulminant Acute Postoperative Morganella morganii Endophthalmitis

ABSTRACT Purpose: The authors present a case of a 60-year-old Indian female presented with sudden loss of vision in the right eye three days after an uneventful cataract surgery which revealed a rare organism and which was treated successfully. Methods: She was diagnosed with acute postoperative endophthalmitis with fulminant disease and on further work up, culture showed Morganella morganii (gram negative bacilli). Results: She was successfully treated with intravitreal imipenem, dexamethasone and vitrectomy. A review of literature was conducted to identify and discuss additional reports on similar cases. As per PubMed search with keywords “Morganella morganii endophthalmitis” this is the best achieved visual outcome to date in a case of acute post-operative Morganella morganii endophthalmitis. Conclusion: Intravitreal imipenem can be considered to treat Morganella morganii endophthalmitis. Aggressive treatment in these patients can help in improving visual outcome.
