Abstract
PURPOSE To assess the association between vitreous hyper-reflective dots (VHD) and the macular thickness changes following uneventful phacoemulsification. METHODS In this prospective cohort study optical coherence tomography (OCT) examinations were performed preoperatively and 1 week, 1 month and 3 months postoperatively in patients undergoing cataract surgery. OCT images were analyzed for retinal central subfield thickness (CST) and preretinal VHDs. Surgeries were recorded for the assessment of lens fragments in the space of Berger. RESULTS 111 eyes of 97 patient were enrolled of whom 69 (62.2%) were female. VHDs were seen in 25 eyes (22.5%) at week 1; in 21 eyes (18.9%) at month 1 and in 3 eyes (2.7%) at month 3. In all eyes with VHDs retro-capsular lens fragments were visible immediately after phacoemulsification. The number of VHDs significantly decreased over the postoperative period. There was a moderate correlation between the number of VHDs and CST at 1 month (r = 0.426, p<0.001). In eyes with VHD the CST averaged 238.8±17.6 μm (214-266) at 1 week; 276.1±63.5 μm (231-481) at 1 month and 285.1±122.3 μm (227-785) at 3 months. In eyes with no detectable VHDs CST averaged 235.9±23.3 μm (192-311) at 1 week; 240.1±21.6 μm (200-288) at 1 month and 242.2±21.3 μm (205-289) at 3 months. Although the differences among the assessment points were relatively low, there was a significant difference in general (p<0.001, Friedman test). CONCLUSION In conclusion, VHDs seem to cause macular thickening throughout the postoperative course. The origin of VHDs is still unknown; however, they presumably represent lens fragments that provoke subclinical inflammation.

Abstract
PURPOSE OF REVIEW Retained lens fragments are a relatively rare occurrence after cataract surgery. While no definite guidelines for the surgical management or timing of surgery of this complication exist, surgery is indicated for patients with large lens fragments, persistent inflammation, secondary glaucoma, corneal edema, retinal tears or detachments, and associated endophthalmitis. The aim of this review is to summarize the current surgical management of retained lens material. RECENT FINDINGS The Intelligent Research in Sight registry database of 2.26 million patients who underwent cataract surgery in the US indicated that 0.18% (1 in 563) had secondary removal of retained lens fragments in the anterior chamber in the operating room within 1 year of the original cataract surgery. The risk of returning to the operating room for retained lens material removal was greater among men, smokers, patients with Medicaid or military insurance, and those who had complex cataract surgery. Medical management with topical corticosteroids or observation may be considered for small lens fragments, but surgical removal remains the mainstay of the treatment for large lens fragments. SUMMARY Retained lens fragments following cataract surgery may result in various vision-threatening complications. Understanding the risk factors, diagnosis, and surgical management of retained lens fragments are critical to preserving good visual outcomes. Vitrectomy is effective in patients with posterior nuclear fragments, retinal detachment, endophthalmitis, or uncontrolled glaucoma not responding to medical management. The best timing for surgery for retained lens fragments should be further investigated in a prospective study.

Abstract
We experienced a rare case of lens-induced uveitis (LIU) with severe proliferative vitreoretinopathy (PVR) diagnosed upon finding lens nuclear material encapsulated by intravitreal proliferative tissue. A 60-year-old man was referred to our hospital for the treatment of vision loss caused by unexplained uveitis in the right eye (OD). Seven months previously, a complicated cataract surgery that required unplanned anterior vitrectomy and transscleral suture of intraocular lens was performed on that eye at another clinic. Severe inflammation with dense vitreous opacity occurred in the OD postoperatively. Although topical and oral administration of steroids reduced the inflammation 7 months after the surgery, PVR with tractional retinal detachment was developed in the OD. Pars plana vitrectomy (PPV) was performed for the treatment and diagnosis. PPV revealed the presence of lens nuclear fragments within the vitreous, which was approximately 60% the ordinary nucleus size and was encapsulated by intravitreal proliferative tissue. The nuclear fragments were extracted from a superior corneoscleral flap. Intraocular inflammation was reduced with postoperative topical and oral steroid treatments and the retina remained reattached 1 year after the PPV. In conclusion, uveitis with an episode of a complicated cataract surgery may suggest LIU.

Vitreous hyper-reflective dots in pseudophakic cystoid macular edema assessed with optical coherence tomography. PLoS One 2017; 12:e0189194. [PMID: 29244855 PMCID: PMC5731694 DOI: 10.1371/journal.pone.0189194] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2017] [Accepted: 11/21/2017] [Indexed: 11/24/2022] Open
Abstract
Purpose This study compares the presence of vitreous hyper-reflective dots (VHDs) detected with optical coherence tomography (OCT) between eyes with pseudophakic cystoid macular edema (CME) and those with no CME after cataract surgery. In addition, we evaluated the impact of VHDs on the responsiveness of pseudophakic CME to cortisone treatment. Setting Department of Ophthalmology, Medical University of Graz, Austria. Design Retrospective, monocenter case-controlled study. Methods Inclusion criteria for the study group and the control group were CME and no CME within 12 weeks following uneventful phacoemulsification in otherwise healthy eyes, respectively. VHDs (number and size) and the macular thickness were assessed with OCT. Furthermore, the number of peribulbar or intravitreal steroid injections was assessed. Results A total of 284 eyes from 267 patients were analyzed, among which 119 met the inclusion criteria for the study (n = 63) and the control group (n = 56). VHDs were observed in 54 (85.7%) study eyes and 21 (37.5%, p = 0.013) control eyes. The number of VHDs was 3.9±3.4 in the study group and 0.7±1 in the control group (p<0.001). The size of the VHDs was 33.5±9.1 μm and 36.6±17.9 μm in the study and control groups, respectively (p = 0.978). Overall, the number of VHDs correlated with central subfield thickness (r = 0.584, p<0.001), cube volume (r = 0.525, p<0.001), and postoperative best-corrected visual acuity (BCVA) (r = -0.563, p<0.001). The number of VHDs did not correlate with the frequency of peribulbar or intravitreal steroid injections. Conclusion VHDs occurred more often in eyes with CME than in eyes without CME following cataract surgery. In addition, the number of VHDs had an impact on the extent of macular thickening and subsequently postoperative BCVA. No correlation was found between the number of VHDs and the frequency of required peribulbar or intravitreal steroid injections.

Abstract
PURPOSE To evaluate the effect of vitrectomy timing on outcomes for patients with crystalline retained lens fragments receiving vitrectomy 3+ days after cataract surgery. DESIGN Systematic review and meta-analysis of retrospective interventional cases series. METHODS Searches of MEDLINE (English, 1/1/85 through 7/30/2010) and article reference lists. Articles were screened for patients with crystalline retained lens fragments after surgery for age-related cataracts, discussion of vitrectomy timing, and, for the meta-analysis, patient totals for at least 1 outcome and multiple time periods, 10+ patients, and mean follow-up ≥3 months. Outcomes included visual acuity, retinal detachment, increased intraocular pressure, intraocular infection/inflammation, cystoid macular edema, and corneal edema. Data extraction was performed twice and quality assessed. Logistic regression estimated study-level odds ratios for each additional 1-week vitrectomy delay. Meta-analysis estimated summary odds ratios using random-effects models. RESULTS Of 257 articles identified, there were 43 unique studies (53 articles) for the systematic review, including 27 (31 articles) for the meta-analysis. Early vitrectomies were statistically significantly associated with better outcomes for not good visual acuity (odds ratio: 1.13; 95% CI: 1.04-1.22, P = .005); bad visual acuity (odds ratio: 1.05; 95% CI: 1.01-1.09, P = .009); previtrectomy retinal detachment (odds ratio: 1.29; 95% CI: 1.01-1.65, P = .038); postvitrectomy retinal detachment (odds ratio: 1.13; 95% CI: 1.02-1.26, P = .024); increased intraocular pressure (odds ratio: 1.23; 95% CI: 1.07-1.41, P = .003); and intraocular infection/inflammation (odds ratio: 1.20; 95% CI: 1.01-1.42, P = .041). Results were robust to sensitivity analyses. CONCLUSIONS This systematic review and meta-analysis found significantly better outcomes (visual acuity, retinal detachment, increased intraocular pressure, intraocular infection/inflammation) with earlier vitrectomy for retained lens fragments. Reduced vitrectomy delays may yield better patient outcomes.

Abstract
Purpose: To evaluate the visual outcome of patients who underwent pars plana vitrectomy (PPV) for posteriorly dislocated lens fragments after phacoemulsification. Methods: A retrospective chart review was conducted of all patients who had PPV for posteriorly dislocated lens fragments after phacoemulsification between January 2000 and September 2004 in the Vitreoretinal Service at King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia. Demographics, preexisting eye diseases, details of the previous cataract surgery, findings at presentation, details of the vitreoretinal procedures, final visual acuity, and complications observed during the follow-up were evaluated. Results: Of the 60 patients identified, 37 patients (37 eyes) had a full set of data and were included in the study. In 21 eyes (56.8%), PPV was performed within 1 week of cataract extraction; in 15 eyes (40.5%), PPV was performed more than 1 week postcataract extraction. An initial visual acuity of 20/200 or worse was found in 34 eyes (91.9%). The final visual acuity was 20/40 or better in 10 eyes (27%), and 20/200 or worse in 13 eyes (35.1%). Retinal detachments were found in 3 eyes (8.1%): 1 before and 2 after vitrectomy. Conclusion: There was no statistically significant difference in outcome between those having vitrectomy the first week after cataract surgery and those having it later; however, there was a trend of better visual outcome in early vitrectomy patients (within 1 week).

Abstract
BACKGROUND AND OBJECTIVE To investigate the antibiotic sensitivities and clinical outcomes of eyes with endophthalmitis caused by methicillin-sensitive versus methicillin-resistant Staphylococcus epidermidis (MSSE/MRSE). PATIENTS AND METHODS A retrospective, consecutive case series of all patients with endophthalmitis caused by S. epidermidis from January 1, 1996, through July 1, 2004, was conducted. The antibiotic sensitivities and clinical outcomes were obtained from the corresponding medical records. RESULTS The study included 86 eyes of 86 patients with S. epidermidis endophthalmitis (34 MSSE and 52 MRSE). Endophthalmitis categories included cataract surgery (58), glaucoma surgery (12), trauma (7), vitrectomy (4), penetrating keratoplasty (4), and corneal suture ulcer (1). In vitro testing revealed that all MSSE and MRSE isolates were sensitive to vancomycin, 67% of MSSE isolates and 67% of MRSE isolates were sensitive to gatifloxacin, and 73% of MSSE isolates and 67% of MRSE isolates were sensitive to moxifloxacin (overall 68% sensitive). All eyes were treated with intravitreal vancomycin and either ceftazidime or amikacin. Visual acuity improved to a median of 20/80 at 3 months and 20/60 at 1 year. I CONCLUSIONS: In the current study, all MSSE and MRSE isolates were sensitive to vancomycin and 68% were sensitive to the fourth-generation fluoroquinolones. There were no significant differences in visual acuity outcomes of endophthalmitis caused by MSSE versus MRSE isolates.

Abstract
PURPOSE To determine characteristics and final visual and surgical outcomes of patients who experienced early onset postoperative inflammation after cataract surgery and their early and late complications. METHODS This is a prospective case series of 126 patients out of 1500 cases who underwent cataract surgery and experienced early onset postoperative inflammation during the first 2 weeks after cataract surgery. All the patients received complete ocular examinations at onset of signs and symptoms of inflammation. A total of 110 patients with follow-up examinations between 3 and 30 months after recovery of early onset postoperative inflammation (mean follow-up 11.6 months) were enrolled in the next part of the study to evaluate the final visual and surgical outcomes. Background systemic and ocular diseases, type of surgery, type of intraocular lenses and viscoelastic agent, early and late complications, and final best-corrected visual acuity were studied. RESULTS Among 1500 patients, 126 cases (8.4%) had early onset postoperative inflammation, 64 cases (50.7%) were male, and 62 cases (49.3%) were female. Early complications were posterior synechia in 9 cases (7.1%), pupillary block in 2 cases (1.5%), and acute rise of intraocular pressure in 6 cases (4.7%). Late complications consisted of posterior capsular opacity in 38 cases (34.5%) and cystoid macular edema in 4 cases (3.2%). Peak of signs and symptoms of inflammation was during 2 weeks after surgery and all patients responded well to topical steroids. Final best-corrected visual acuity (BCVA) was 20/30 and better in 76 cases (69%), between 20/40 and 20/80 in 24 cases (22%), and less than 20/80 in 10 cases (9%). All cases with BCVA less than 20/80 had ocular diseases like choroidal neovascularization scar or age-related macular degeneration, advanced glaucoma, or corneal opacity. CONCLUSIONS Early onset postoperative inflammation causes pain, decreased vision, and patient anxiety in the acute phase but neither decreases final visual acuity nor has any significant or permanent ocular sequels.

Abstract
PURPOSE To assess the outcomes in patients who required 1 or more vitreoretinal interventions for posterior segment complications arising from elective uneventful cataract surgery. SETTING Tertiary referral center, single-center study. METHODS A retrospective interventional case series included 56 consecutive patients who were referred for surgical correction of posterior segment complications within 6 months of cataract surgery. The study period was between 1996 and 2003, and the minimum follow-up was 5 months. RESULTS Posterior segment complications were resolved with a single surgical intervention in 40 cases (71.4%). Within 5 months of primary surgical correction, persisting or newly arising posterior segment complications were noted in 16 cases (28.6%). After a mean of 2.1 +/- 1.4 (SD) additional surgeries, the number of eyes with posterior segment problems decreased to 7 (12.5%) (P = .035). Posterior segment complications requiring more than 1 vitreoretinal intervention included retinal detachment, endophthalmitis, and choroidal hemorrhages. After primary correction surgery, the mean best corrected visual acuity increased from 0.15 +/- 0.24 to 0.37 +/- 0.33 (P = .001) after a single intervention and to 0.39 +/- 0.32 (P>.05) after additional interventions. Although the intraocular pressure (IOP) decreased from 21.8 +/- 16.6 mm Hg to 14.9 +/- 3.4 mm Hg (P = .008), 4 (7.1%) consecutive vascular optic atrophies occurred. A reduction in corneal transparency was observed in 46.4% of patients before primary surgical correction and 12.5% after primary surgical correction (P<.001). CONCLUSIONS In many cases, posterior segment complications arising from cataract surgery could be repaired with favorable functional and anatomical outcomes by a single vitreoretinal intervention. Additional surgery, if requested, provided stabilization of the anatomical and functional outcomes.

Abstract
PURPOSE To investigate the clinical features, visual acuity outcomes, and adverse events in patients with retained lens fragments managed by pars plana vitrectomy (PPV). DESIGN Retrospective, noncomparative, consecutive case series. METHODS Medical records of all patients who underwent PPV for retained lens fragments at Bascom Palmer Eye Institute during the 12-year interval between January 1, 1990, and December 31, 2001, were reviewed. RESULTS The study included 343 eyes of 343 patients, with a median age of 76 years and a median follow-up after PPV of 8 months. The median interval between cataract surgery and PPV was 12 days. Visual acuity was >or=20/40 in 29 (9%) patients preoperatively and 190 (56%) at last follow-up (P < 0.001). Visual acuity was <or=20/200 in 224 (66%) patients preoperatively and 67 (20%) at last follow-up (P < 0.001). An intraocular pressure (IOP) >or=30 mmHg was present in 87 (25%) eyes preoperatively and 7 (2%) at last follow-up (P < 0.001); the number of patients on antiglaucoma medications at these two time points was 135 (40%) and 96 (29%), respectively (P = 0.001). Among the 148 (44%) patients with final vision <20/40, the primary cause of visual impairment was cystoid macular edema (CME) in 41 (29%), preexisting ocular disease in 34 (24%), corneal edema in 22 (15%), history of retinal detachment (RD) in 19 (13%), epiretinal membrane in 6 (4%), and other causes in 21 (15%). Significant predictors of better final visual acuity include better presenting visual acuity (P < 0.001), presence of an intraocular lens (i.e., no aphakia) before PPV (P = 0.026), no suprachoroidal hemorrhage (P = 0.010), no serous choroidal detachment (P = 0.037), no RD (P = 0.005), no CME (P = 0.038), and no additional surgery after the PPV (P < 0.001). Timing of PPV (i.e., <or=1 week versus >1 to <or=4 weeks versus >4 to <or=12 weeks versus >12 weeks between cataract surgery and PPV) was not significantly associated with final visual acuity or IOP outcome; there was also no significant difference in acuity or IOP outcome between patients who underwent PPV on the same day as cataract surgery compared with all other patients. CONCLUSIONS The most important predictor of final visual acuity after PPV for retained lens fragments is a less complicated clinical course (e.g., no suprachoroidal hemorrhage, no RD, no CME, and no additional surgery after PPV). The most common cause of decreased final vision was CME.

Abstract
PURPOSE To investigate the incidence and outcomes of retinal detachment (RD) associated with retained lens fragments removed by pars plana vitrectomy (PPV). DESIGN Retrospective, noncomparative, interventional consecutive case series. PARTICIPANTS All patients who underwent PPV for retained lens material after cataract surgery at Bascom Palmer Eye Institute between January 1, 1990, and December 31, 2001. METHODS Demographic and clinical data were extracted from patients' medical records. MAIN OUTCOME MEASURES Incidence of retinal detachment, reattachment rate, and visual acuity outcome. RESULTS RD occurred in 44 of 343 (12.8%) patients, including 25 (7.3%) before or during PPV and 19 (5.5%) after PPV. The RD was macula-on in 22 of 44 (50%) patients and macula-off in 22 of 44 (50%) patients. The RD was associated with a giant retinal tear in 7 of 44 (15.9%) patients, limited suprachoroidal hemorrhage in 3 of 44 (6.8%) patients, and endophthalmitis in 4 of 44 (9.1%) patients. Retinal reattachment was achieved in 40 of 44 (90.9%) patients; 14 of 44 (31.8%) patients underwent one or more additional procedures for recurrent detachment. Final visual acuity in the patients in this series was >/=20/40 in 8 of 44 (18%), 20/50 to 20/100 in 13 of 44 (30%), 20/200 to 5/200 in 13 of 44 (30%), and <5/200 in 10 of 44 (23%). In the 36 patients with vision less than 20/40, the primary causes of decreased vision were attributed to prior history of RD in 8 of 36 (22.2%), corneal edema in 7 of 36 (19.4%), cystoid macular edema in 5 of 36 (13.9%), persistent retinal detachment in 4/36 (11.1%), preexisting primary open-angle glaucoma in 4 of 36 (11.1%), age-related macular degeneration in 3 of 36 (8.3%), epiretinal membrane in 2 of 36 (5.5%), macular hole in 1 of 36 (2.7%), optic atrophy in 1 of 36 (2.7%), and irregular astigmatism in 1 of 36 (2.7%) patients. CONCLUSIONS RD is a frequent complication in eyes undergoing PPV for removal of retained lens fragments. Despite favorable retinal reattachment rates, visual acuity outcomes are often poor in these eyes and are associated with other comorbidities such as corneal edema and cystoid macular edema. Poor initial visual acuity and the presence of a retinal tear at the time of PPV were associated with a higher rate of RD after PPV.

Abstract
Posterior dislocation of lens fragments is a well-known complication of phacoemulsification. Retained lens material in the vitreous cavity can lead to poor visual acuity related to inflammation, corneal edema, and glaucoma. Pars plana vitrectomy is frequently necessary to remove the dislocated lens fragments. The optimal timing of vitrectomy has not been firmly established. Several large studies have failed to establish an association between timing of vitrectomy and visual outcome. However, others suggest that earlier vitrectomy may lead to improved visual outcomes and lower rates of chronic glaucoma. Excellent outcomes are possible for patients undergoing vitrectomy for retained lens fragments. Retinal detachment is the most common cause of poor visual acuity in these patients. The risk of retinal detachment is correlated with vitreous manipulation by the cataract surgeon in attempts to retrieve dislocated lens material. Therefore, if both the anterior segment and vitreoretinal surgeons rigorously avoid vitreous traction in these cases, a good visual prognosis is expected.

Abstract
PURPOSE To evaluate the visual outcome of patients with posteriorly dislocated lens fragments after phacoemulsification managed with pars plana vitrectomy (PPV) and identify risk factors for poor visual outcome. SETTING Vitreo-Retinal Service, St. Paul Eye Unit, Liverpool, United Kingdom. METHODS The medical records of all patients who had PPV for posteriorly dislocated lens fragments after phacoemulsification between March 1993 and August 1998 were retrospectively reviewed. Demographics, preexisting eye conditions, details of the previous cataract surgery, findings at presentation, details of the vitreoretinal procedure, final visual acuity, and complications observed during the follow-up were evaluated. Univariate and multiple regression analyses were used to determine the significance of these clinical variables as determinants of poor visual outcome (visual acuity 6/12 or worse). RESULTS Of the 106 patients identified, 89 had a full set of data and were included in the study. In 79 patients (89%), PPV was performed from 1 to 357 days (median 15 days) after cataract extraction. In 10 patients (11%), PPV was done on the same day as the cataract surgery. Sixty-two patients (69%) had a final visual acuity of 6/12 or better. Preexisting eye disease (P <.01), PPV delayed for more than 4 weeks (P <.03), occurrence of retinal detachment after vitrectomy (P <.01), and the use of ultrasound (US) fragmentation (P <.01) were statistically significantly correlated with a poor visual outcome. CONCLUSIONS Posterior dislocated lens fragments after phacoemulsification were safely retrieved using PPV. It appears that intervening early (within 4 weeks) and avoiding the use of US fragmentation are associated with a better visual outcome and reduced rate of postoperative complications.

Abstract
Endophthalmitis is an inflammatory reaction of intraocular fluids or tissues. Infectious endophthalmitis is one of the most serious complications of ophthalmic surgery. Occasionally, infectious endophthalmitis is the presenting feature of an underlying systemic infection. Successful management of infectious endophthalmitis depends on timely diagnosis and institution of appropriate therapy. Recognition of the different clinical settings in which endophthalmitis occurs and awareness of the highly variable presentation it may have facilitate timely diagnosis. Biopsy of intraocular fluid/tissue is the only method that permits reliable diagnosis and treatment. The different presenting clinical settings, a rational approach to diagnosis (i.e., when, what, and how to biopsy), and the treatment of infectious endophthalmitis are reviewed.
