[PMID: 37723463 PMCID: PMC10506304 DOI: 10.1186/s12886-023-03113-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 08/22/2023] [Indexed: 09/20/2023] Open
Abstract
BACKGROUND Post-cataract macular edema (PCME) is a condition that can occur in patients following cataract surgery without risk factors and complications. Although 80% of patients experience spontaneous resolution after 3 to 12 months, in persistent cases, it can lead to permanent vision loss if left untreated. There are currently no standardized treatment guidelines for PCME, and there have been limited studies showing the impact of PCME on annual Medicare spending and ophthalmology-related outpatient visits per case compared to those without the complication. This study aims to evaluate real-world treatment patterns and the economic burden of patients with PCME. METHODS This retrospective claims analysis identified patients from the IBM® MarketScan® Commercial and Medicare Supplemental databases. Patients with (n = 2430) and without (n = 7290) PCME 1 year post cataract surgery were propensity score matched 1:3 based on age, geographic region, diabetes presence, cataract surgery type, and Charlson Comorbidity Index. Treatment pattern analysis for each PCME patient summarized the distribution of medications across lines of therapy. Economic burden analysis compared the mean number and costs of eye-related outpatient visits, optical coherence tomography imaging scans, and ophthalmic medications between the 2 groups using linear regression models. RESULTS Treatment pattern analysis found 27 different treatment combinations across 6 treatment lines. The most common first-line treatments were topical steroid drops (372 [30%]), topical nonsteroidal anti-inflammatory drug drops (321 [27%]), and intraocular or periocular injectable steroids (189 [15%]). Compared to match controls, PCME patients averaged 6 additional eye-related outpatient office visits (95% CI: 5.7-6.2) resulting in an additional $3,897 (95% CI: $3,475 - $4,319) in total costs. Patients filled 3 more ophthalmology-related outpatient prescription medications (95% CI: 2.8-3.2), adding $371 in total cost (95% CI: $332 - $410). CONCLUSIONS PCME treatment patterns showed wide clinical variability in treatments and time, specifically regarding injectable treatments and combination therapy. Additionally, significantly higher healthcare resource use and economic burden were found for both patients and payers when comparing PCME patients to non-PMCE controls. These results highlight the need for treatment standardization and demonstrate that interventions targeted at preventing PCME may be valuable.

Factors predictive of cystoid macular oedema following endothelial keratoplasty: a single-centre review of 2233 cases. Br J Ophthalmol 2023; 107:24-29. [PMID: 34301611 DOI: 10.1136/bjophthalmol-2020-318076] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Accepted: 07/06/2021] [Indexed: 11/04/2022]
Abstract
AIMS To describe the incidence of postoperative cystoid macular oedema (CMO) after endothelial keratoplasty (EK) and to identify its contributory risk factors. METHODS 2233 patients undergoing EK at Ospedali Privati Forlì 'Villa Igea', between January 2005 to October 2018 for Descemet stripping automated endothelial keratoplasty (DSAEK) and June 2014 to August 2018 for Descemet membrane endothelial keratoplasty (DMEK) with a minimum follow-up of 18 months were evaluated. Univariate and multivariate analyses were conducted to identify and quantify contributory risk factors. Receiver operating characteristic (ROC) curve analysis were performed to determine ideal cut-off points of continuous variables. RESULTS CMO was identified in 2.82% (n=63) of the cases. CMO occurred in 2.36% of DSAEK eyes and in 5.56% of DMEK eyes (p=0.001). Average onset of CMO was 4.27±6.63 months (range: 1-34 months) postoperatively. Compared with those who did not develop CMO, a higher proportion of patients in the CMO group had diabetes (24.2% vs 9.8%, p<0.001) (OR=3.16, 95% CI: 1.72 to 5.81, p<0.001), a higher proportion of patients who underwent DMEK rather than DSAEK (28.6% vs 14.1%, p=0.001) (OR=2.42, 95% CI: 1.35 to 4.33, p=0.003) and were older (70.5±10.0 vs 67.1±14.3 years, p=0.01). Using the cut-off of 67 years as identified by ROC curve analysis, subjects aged >67 years (OR=2.35, 95% CI: 1.30 to 4.26, p=0.005) were more likely to develop CMO. There were no other significant differences between the groups. CONCLUSIONS Older age (>67 years), diabetes mellitus and DMEK have been identified as independent risk factors for postoperative CMO following EK. Close observation is necessary during the first postoperative year after EK, particularly in patients with risk factors.

Safety of the bag-in-the-lens implantation regarding the development of clinically significant pseudophakic cystoid macular edema: A retrospective case series study. PLoS One 2023; 18:e0278861. [PMID: 36607976 PMCID: PMC9821458 DOI: 10.1371/journal.pone.0278861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Accepted: 11/25/2022] [Indexed: 01/07/2023] Open
Abstract
PURPOSE To determine the incidence of clinically significant pseudophakic cystoid macular edema (CSPME) after phacoemulsification using the 'bag-in-the-lens' lens (BIL) implantation technique and to examine the influence of associated risk factors for clinically significant pseudophakic macular edema (CSPME), both ocular and systemic. METHODS This retrospective study included 2419 first-operated eyes of 2419 adults who underwent phacoemulsification cataract surgery using the BIL implantation technique between January 2013 and December 2018 in the Antwerp University Hospital, Belgium. The significance of several risk factors (age, gender, previous history, intra- and postoperative complications) was examined by extraction of electronic medical files. RESULTS The 3-month incidence of CSPME in the subgroup without risk factors was 0.00% (95% CI: 0.00 -NA). The 3-month incidence of CSPME in the subgroup with risk factors was 0.57% (95% CI 0.22-1.29%). The 3-month incidence of CSPME in the total population of 2419 patients was 0.29% (95% CI: 0.11-0.65%). The risk factors most significantly associated with CSPME included renal insufficiency (hazard ration [HR]: 5.42; 95% CI: 1.69-17.44; P = .014), exudative age-related macular degeneration (HR: 74.50, 95% CI: 25.75-215.6; P < .001) and retinal vein occlusion (HR: 22.48, 95% CI: 4.55-111.02; P = .005). CONCLUSIONS In the absence of risk factors, the incidence of CSPME was zero. We can conclude that Primary Posterior Continuous Curvilinear Capsulorhexis (PPCCC) does not increase the risk for CSPME. Non-inferiority of the BIL implantation regarding the development of CSPME, relative to the traditional 'lens-in-the-bag' (LIB) implantation, confirms that BIL is a safe surgical technique. This study also illustrates a previously undescribed risk factor for developing CSPME, namely renal insufficiency.

Abstract
ABSTRACT The incidence of pseudophakic cystoid macular edema (PCME) ranges from 0.1% to 20% and is the most common cause of post-procedure vision loss. Currently there is no widely accepted treatment for PCME. Topical non-steroidal anti-inflammatory (NSAID) drops given alone or in combination with topical corticosteroids are often used; however, there is a growing body of literature surrounding the off-label use of various ocular injectable medications. The purpose of this systematic literature review was to characterize the current evidence surrounding these treatments and conduct qualitative analysis to assess the risk for bias of each study. Eighteen total studies were found and evaluated to have moderate (n=3, 17%) to high risk (n=15, 83%) of bias. Although the growing body of real-world data favors improvements in visual acuity and anatomical outcomes with these injectable treatments, larger studies with better study design are needed to demonstrate their role in the management of PCME.

Abstract
PURPOSE OF REVIEW Given the epidemiology and demographic trends of diabetes mellitus and cataracts, ophthalmologists are likely to encounter patients with both comorbidities at an increasing frequency. Patients with diabetes represent a higher risk population than healthy patients for cataract surgery. In this review, we discuss key risks and risk-mitigation practices when performing cataract surgery on these patients. RECENT FINDINGS Patients with diabetes continue to represent a high-risk surgical population: Nagar et al. suggest a dose-dependent relationship may exist between number of intravitreal injections and likelihood of posterior capsular rupture. However, novel treatments are improving outcomes for patients with diabetes. Several studies have reported intracameral phenylephrine/ketorolac may reduce the incidence of post-operative cystoid macular edema while others have discussed the efficacy of pre-treatment and post-treatment with intravitreal bevacizumab on improving cataract surgery outcomes in patients with diabetic retinopathy. Pre-operatively, ophthalmologists should perform an enhanced evaluation, consider timing and lens selection decisions, and complete any appropriate pre-operative treatment. Peri-operatively, surgeons should be aware of pupillary dilation adjustments, combination surgery options, and potential complications. Post-operatively, clinicians should address pseudophakic cystoid macular edema, diabetic macular edema, diabetic retinopathy, and posterior capsular opacification.

Abstract
PURPOSE The topical nonsteroidal anti-inflammatory drug bromfenac 0.09% has a potential benefit in uveitic macular edema (UME) with a safe side effect profile. The aim of the study is to assess the efficacy of bromfenac sodium solution in the treatment of UME. METHODS The charts of 10 patients with macular edema due to noninfectious uveitis treated with bromfenac 0.09% were reviewed retrospectively. The main outcomes studied were the best-corrected visual acuity (BCVA) and the central retinal thickness (CRT) compared 4 months before bromfenac initiation, at the time of its initiation, and 4 months later. RESULTS Twelve eyes of 10 patients were included. BCVA and CRT were unchanged 4 months befoew bromfenac compared to the time of bromfenac initiation (P = 1.0 and P = 0.2, respectively). There were a significant improvement in BCVA after 4 months of bromfenac treatment (P = 0.043) and a significant decrease in CRT (P = 0.002). Subretinal fluid resolved completely in 8/9 eyes, and 4/9 eyes had a complete resolution of cystoid macular edema at 4 months. CONCLUSION Bromfenac may be a useful addition to the treatment of UME.

Abstract
Purpose The aim of this study was to investigate safety and comfort of two versions of a placebo-microsphere filled ocular coil (straight and curved) in healthy subjects. Methods The study was a single-center intervention study. One ocular coil was placed in the inferior conjunctival fornix for the intended duration of 28 days. Forty-two healthy adult subjects were included. At baseline, 30 minutes, 8 hours, 24 hours, 48 hours, 7 days, 14 days, 21 days, and 28 days after insertion, examinations were performed, including slit lamp evaluation to score ocular redness, intraocular pressure measurement, visual acuity, tear secretion test, and questionnaires. Results The straight and curved ocular coils had a median retention time of 5 days and 12 days, respectively. After 48 hours, 57% and 81% subjects retained the straight and curved ocular coil, respectively. Four (19%) subjects with the straight coil and six (29%) with the curved coil completed the entire study period. Minor changes in ocular hyperemia were observed in both groups. On day 7, the straight coil was more comfortable than the curved coil with a visual analogue scale (VAS) score of 77 ± 21 compared to 94 ± 11 (P = 0.028), respectively. No other ocular adverse events were observed. Conclusions Comfort and safety of the straight and curved ocular coil are high. Because the retention time is too short for long-term sustained drug release, the use in the perioperative or immediate postoperative period could prove to be more valuable. Translational Relevance The ocular coil is a noninvasive, comfortable and safe short-term drug delivery device.

Abstract
Purpose To assess the effect of twice-daily nepafenac ophthalmic suspension 0.3% on postoperative cystoid-macular-edema (CME). Patients and Methods In this prospective, clinic-based, non-randomized case-series, 21 patients (21 eyes) were enrolled with either acute or chronic postoperative CME after cataract extraction. Patients were treated with twice-daily nepafenac 0.3% drops, and followed for at least a 4-month period. Best-corrected visual acuity (BCVA) and spectral-domain optical coherence tomography (SD-OCT)-derived central retinal thickness (CRT) were measured. Results From 21 patients, eight presented with acute postoperative CME and 13 with chronic CME. Mean follow-up was 4.82±1.24 months. No adverse events were reported during the study. Baseline BCVA was 0.49±0.36 logMAR and improved to 0.36±0.42 logMAR at the last follow-up visit (P<0.005). CRT decreased from 450.40±90.74 μm at baseline to 354.60±81.49 μm (P<0.05), following treatment. Conclusion Our outcomes strongly suggest that administrating nepafenac 0.3% drops on a twice-daily regimen could be a promising alternative for the management of postoperative CME. Additional studies are necessary to further validate our results.

Abstract
AIM To compare the efficacy of bevacizumab, ranibizumab, and aflibercept in pseudophakic cystoid macular edema (CME) patients with Irvine-Gass syndrome (IGS). METHODS This study is designed as retrospective consecutive case series. Those who developed postoperative pseudophakic CME that refractory to topical treatment and were treated with anti-vascular endothelial growth factor (VEGF) agents included in the study. Optical coherence tomography (OCT) examination including central macular thickness (CMT), total macular volume (TMV), retinal nerve fiber layer (RNFL), ganglion cell layer (GCL) and choroidal thickness (ChT) measurements at the baseline, 1st, 3rd and 6th month controls were performed. RESULTS Fifty-nine eyes of 59 patients with CME and other healthy eyes of the patients (Control group) were evaluated. There were 22 eyes of 22 patients in the bevacizumab group (group 1), 19 eyes of 19 patients in the ranibizumab group (group 2), and 18 eyes of 18 patients in the aflibercept group (group 3). There was no difference in terms of age, gender, axial length, IOP, and spherical equivalent values. The baseline subfoveal and mean ChT were higher in the IGS group. The difference between the baseline and sixth month values of subfoveal and mean ChT were compared in the CME groups, thinning was observed in all three groups. GCL was thinner in the patient group at the 6th month of treatment. The resolution time of CME was observed faster in group 1. CONCLUSION All three anti-VEGF agents seem to be effective in CME but bevacizumab appears to be slightly more cost-effective than the other two alternatives.

Abstract
PURPOSE To evaluate, by laser photometry, the persistency of anterior chamber flare after uneventful phacoemulsification in asymptomatic patients with no signs of inflammation on slit lamp examination. METHOD Seventy-five patients previously enrolled in a randomized clinical trial that evaluated inflammation after uneventful phacoemulsification in eyes treated with dexamethasone 0.1% ophthalmic suspension (group 1) or bromfenac 0.09% ophthalmic solution (group 2) for 2 weeks. Anterior chamber inflammation was investigated by laser flare photometry. At 30 days after surgery, laser flare showed persistently elevated values. For this reason, patients were further analyzed at 3 and 6 months. Additionally, optical coherence tomography was used to measure the central macular thickness (CMT) and to assess for postoperative pseudophakic macular edema. RESULTS When compared to preoperative values, laser flare photometry demonstrated persistent ocular inflammation at postoperative days 90 and 180 in group 1, but not in group 2. Laser flare values showed a significant reduction in group 2 compared to group 1 throughout all the follow-up (p < 0.001). The increase in mean CMT at days 90 and 180 with respect to baseline was statistically significant in group 1 but not in group 2, in which it decreased to levels similar to preoperative value. Group 1 showed a higher increase in mean CMT compared to group 2 throughout all the follow-up (p < 0.001). The proportion of patients that developed pseudophakic cystoid macular edema (CME) was 14% (n = 5) and 0% (n = 0) in group 1 and group 2, respectively (p = 0.02). The bivariate analysis demonstrated a positive correlation between laser flare and CMT values in group 1 but not in group 2. CONCLUSION Anterior chamber inflammation persists for more than 30 days in a significant proportion of patients after uncomplicated cataract surgery and may be responsible for late onset of cystoid macular edema cases.

Abstract
Since their first introduction in ophthalmology, the use of NSAIDs (nonsteroidal anti-inflammatory drugs) has been exponentially expanded, with numerous therapeutic applications. Despite their controversial history, they have proven their efficacy as anti-inflammatory agents in a variety of diseases. Nowadays, NSAIDs are part of surgical protocols of the most commonly performed ophthalmic operations, such as cataract or ocular surgery. They are universally implicated in the management of conjunctivitis, retinal and choroidal disease and miscellaneous inflammatory diseases. Moreover, although linked with serious adverse events and toxicities, their therapeutic magnitude in Ophthalmology should not be affected. This review systematically portrays the variety of ocular NSAIDs available to date, along with their differences in their way of action, indications and potential side effects in various ophthalmologic conditions.

Abstract
PURPOSE To determine the incidence of clinically significant pseudophakic cystoid macular edema (CSPME) after phacoemulsification using the bag-in-the-lens intraocular lens (BIL IOL) implantation technique and to examine the influence of associated risk factors, both ocular and systemic. SETTING Monocentric, Antwerp University Hospital, Belgium. DESIGN Retrospective. METHODS This study included 1 077 first-operated eyes of 1 077 adults who underwent phaco-emulsification cataract surgery using the BIL IOL implantation technique between January 2013 and December 2015. RESULTS The 3-month incidence of CSPME in the subgroup without risk factors was 0% (95% CI, 0.0-0.0). The 3-month incidence of CSPME in the subgroup with risk factors was 2.8% (95% CI, 1.3-4.3). The 3-month incidence of CSPME in the total group of 1077 patients was 1.4% (95% CI, 0.6-2.1). The risk factors most significantly associated with CSPME included diabetes (hazard ratio [HR]: 5.37; 95% CI, 1.5-19.3; P = .019), exudative age-related macular degeneration (HR: 121; 95% CI, 36.1-409; P < .001), and macular traction (HR: 6.47; 95% CI, 1.9-22.1; P < .009). CONCLUSIONS The incidence of CSPME was zero in eyes without risk factors. The incidence was consistent with previous reports in the literature regarding the lens-in-the-bag IOL implantation technique in eyes with risk factors. This indicates that the BIL IOL implantation technique is a safe procedure and does not confer a higher risk for developing cystoid macular edema after cataract surgery compared with the lens-in-the-bag IOL implantation technique, despite the requirement of a primary posterior continuous curvilinear capsulorhexis.

Abstract
PURPOSE To assess the visual outcomes of pseudophakic cystoid macular edema (CME) as compared with age- and copathology-matched control subjects, the costs of treatment and follow-up, and the patient-reported outcomes using the new Cat-patient-reported outcome measures (PROM) 5 questionnaire. SETTING West Suffolk Hospital NHS Foundation Trust, United Kingdom. DESIGN Matched case-control study. METHODS Fifty-two eyes of 49 patients developed CME over an 18-month period. Age- and copathology-matched patients were identified from clinical records over the same time period in a 2:1 ratio (90 eyes). Postoperative clinical outcomes were recorded including treatments received, costs of treatments, and patient-reported outcome measures using the Cat-PROM5. RESULTS Patients with CME reported a significantly worse outcome from surgery than control subjects. Furthermore, patients with CME had significantly worse visual acuity postoperatively than control subjects (CME: logarithm of the minimum angle of resolution 0.40 ± 0.33, n = 37; control subjects: 0.30 ± 0.33; P < .05) despite there being no difference in preoperative visual acuity. In patients with epiretinal membrane (ERM), notably those with CME had worse patient-reported outcomes than control subjects with ERM, and only 18% received prophylactic corticosteroid injection at surgery compared with 63.6% of control subjects. CME resulted in an excess of 266 outpatient appointments, with 388 weeks of topical therapy, 18 orbital floor injections, 6 intravitreal steroid injections, 5 intravitreal antivascular endothelial growth factor injections, and 1 intravitreal dexamethasone implant with an excess expenditure of £216.81 per case. CONCLUSIONS Patients developing CME after cataract surgery had reduced visual acuity at 4 to 6 weeks, patient-reported visual outcomes, and increased number of hospital appointments, treatments, and costs.

Abstract
PURPOSE To compare the efficacy of bromfenac 0.09% and dexamethasone 0.1% in the treatment of anterior chamber inflammation after uncomplicated cataract surgery. METHODS Seventy-six patients with senile cataracts and no other ocular comorbidities who underwent uneventful phacoemulsification were randomized 1:1 to receive dexamethasone ophthalmic suspension 0.1% or bromfenac ophthalmic solution 0.09% for 2 weeks. All patients were examined on the day before surgery and postoperatively at day 1, 3, 7, 9, 11, 14 and 30. Laser flare photometry was used to quantify anterior chamber inflammation and optical coherence tomography to measure macular thickness. RESULTS Bromfenac was as effective as dexamethasone in reducing inflammation in the anterior chamber of the eye. Laser flare increased the day after surgery and progressively decreased after starting the treatment with no statistically significant difference between dexamethasone and bromfenac at all time points. Visual acuity improved steadily after surgery in both groups. Mean macular thickness was similar in both the dexamethasone and bromfenac arms at 1 month. CONCLUSIONS Short-term therapy with topical bromfenac alone is as effective as dexamethasone in low-risk cataract surgery patients.

Abstract
In the past decade, novel lamellar keratoplasty techniques such as Deep Anterior Lamellar Keratoplasty (DALK) for anterior keratoplasty and Descemet stripping automated endothelial keratoplasty (DSAEK)/Descemet membrane endothelial keratoplasty (DMEK) for posterior keratoplasty have been developed. DALK eliminates the possibility of endothelial allograft rejection, which is the main reason for graft failure after penetrating keratoplasty (PK). Compared to PK, the risk of endothelial graft rejection is significantly reduced after DSAEK/DMEK. Thus, with modern lamellar techniques, the clinical problem of endothelial graft rejection seems to be nearly solved in the low-risk situation. However, even with lamellar grafts there are epithelial, subepithelial and stromal immune reactions in DALK and endothelial immune reactions in DSAEK/DMEK, and not all keratoplasties can be performed in a lamellar fashion. Therefore, endothelial graft rejection in PK is still highly relevant, especially in the "high-risk" setting, where the cornea's (lymph)angiogenic and immune privilege is lost due to severe inflammation and pathological neovascularization. For these eyes, currently available treatment options are still unsatisfactory. In this review, we will describe currently used keratoplasty techniques, namely PK, DALK, DSAEK, and DMEK. We will summarize their indications, provide surgical descriptions, and comment on their complications and outcomes. Furthermore, we will give an overview on corneal transplant immunology. A specific focus will be placed on endothelial graft rejection and we will report on its incidence, clinical presentation, and current/future treatment and prevention options. Finally, we will speculate how the field of keratoplasty and prevention of corneal allograft rejection will develop in the future.

Abstract
Purpose: To report tolerability, safety, and efficacy of a topical triamcinolone acetonide-loaded liposomes formulation (TA-LF) in targeting the macular area in patients with refractory pseudophakic cystoid macular edema (PCME). Methods: For tolerability, safety and efficacy evaluation, 12 eyes of 12 patients with refractory PCME were exposed to one drop of TA-LF (TA at 0.2%) every 2 h for 90 days or until best-corrected visual acuity (BCVA) was achieved. Intraocular pressure (IOP), slit lamp examination, and central foveal thickness (CFT) were analyzed at every visit. Results: Patients with refractory PCME under TA-LF therapy showed a significant improvement in BVCA and CFT without significant IOP modification (P = 0.94). On average CFT decreased to 206.75 ± 135.72 μm and BCVA improved to 20.08 ± 10.35 letters (P < 0.0005). BCVA was achieved at 10.58 ± 6.70 weeks (range 2–18). TA-LF was well tolerated in all cases. Neither ocular surface abnormalities nor adverse events were recorded. Conclusion: TA-LF was well tolerated and improved BCVA and CFT on patients with refractory PCME.

Abstract
Purpose: The purpose of this study is to determine factors predicting resolution of acute pseudophakic cystoid macular edema (PCME) after 6 weeks of topical prednisolone and nepafenac application. Methods: Case records of patients with a clinical and optical coherence tomography (OCT)-based diagnosis of acute PCME were retrospectively reviewed for best-corrected visual acuity and OCT-based parameters at the time of presentation with PCME. In addition, demographic variables, intraoperative and early postoperative factors, and type of treatment prescribed (tapering vs. nontapering prednisolone, generic vs. branded prednisolone and nepafenac) were recorded from case records for analysis. Complete and any successes were defined and baseline factors predicting complete success at 6 weeks were analyzed. Results: We analyzed 69 eyes of 69 patients out of which complete success with topical medications was seen in 37 eyes (54%) and any success was seen in 55 eyes (80%) at 6 weeks. Multivariable logistic regression showed that eyes with lower vision at presentation had a significantly lower likelihood of experiencing both, complete (odds ratio [OR] = 0.83 with one-line decrement in baseline vision, 95% confidence interval [CI] = 0.61–0.89, P = 0.003) and any success (OR = 0.61, 95% CI = 0.4–0.9, P = 0.007). Baseline OCT thickness did not influence success rates. Conclusion: Topical prednisolone and nepafenac lead to resolution in PCME in half of the eyes at 6 weeks. Baseline vision is the only factor predicting rates of success and PCME resolution with topical medications.

Abstract
Purpose To report the efficacy and safety of interferon alpha 2b in the treatment of pseudophakic cystoid macular edema resistant to conventional therapy. Observations A 64-year-old patient presented with pseudophakic cystoid macular edema in her left eye, which developed two months after an uncomplicated cataract surgery and was resistant to multiple topical NSAIDs and multiple intravitreal bevacizumab injections over the course of nine months. She also developed side effects to oral acetazolamide and intravitreal triamcinolone injection; a skin rash and a rise in intraocular pressure (34 mmHg), respectively. She was subsequently started on topical interferon alpha 2b (1 MIU/ml) four times a day nine months after developing pseudophakic cystoid macular edema. Cystoid macular edema improved significantly in four weeks and completely resolved after twelve weeks. Her vision improved from 20/100 before starting treatment to 20/25 twelve weeks after starting treatment. Macular structure and visual acuity were stable throughout a thirty-six weeks follow-up period. Conclusions and Importance: This case report displays the potential efficacy and safety of interferon alpha 2b in the treatment of refractory cystoid macular edema after cataract surgery. Ocular surface irritation was the only reported adverse effect of the treatment in our patient, this responded to lubricants.

Abstract
Cataract surgery can cause macular thickness change. We used optical coherence tomography (OCT) to assess the macular thickness of different regions after femtosecond laser–assisted cataract surgery of age-related cataracts (ARC) and myopia cases with cataract (myopia group). Fifty eyes of 50 patients in ARC group and fifty eyes of 50 patients in myopia with cataract group were included. All study underwent femtosecond laser–assisted cataract surgery and macular thickness of was measured at pre-operation and 1 week, 1 month after surgery. There are significant differences of foveal thickness (P = 0.02), foveal volume (P = 0.02) and average retinal thickness (P = 0.02) between two groups before operation. In the myopia group, statistically significant differences were not found in postoperative macular thickness as compared with ARC group. There are differences in macular thickness between pre-operation and 1 month after operation when compared with nasal outer macular ring thickness (P = 0.022), foveal volume (P = 0.005) and average retinal thickness (P = 0.012) in ARC group. The study suggest that femtosecond laser–assisted cataract extraction is safe in myopia group that did not cause significant increase of macular thickness. However, an increased post-operative local macular thickness was recoded while comparing macular thickness with the baseline in ARC group.

Abstract
Since its first description, the prevention of pseudophakic cystoid macular edema (PCME) continues to pose challenges for ophthalmologists. Recent evidence suggests that prophylaxis is unnecessary in patients without risk factors. Diabetes mellitus is generally considered as a risk factor for the development of PCME after cataract surgery since it causes breakdown of the blood–retinal barrier. Diabetic retinopathy (DR) increases the risk even further. Therefore, prophylactic nonsteroidal anti-inflammatory drugs (NSAIDs) should be considered in diabetic patients, especially if they have DR. NSAIDs block the cyclooxygenase enzymes responsible for prostaglandin production and reduce the incidence of PCME after cataract surgery. Nepafenac seems superior to other NSAIDs in terms of ocular penetration allowing higher and sustained therapeutic levels in retina and choroid. Topical steroids are less effective and may cause intraocular pressure increase limiting their long-term use. Nepafenac is cost effective, when the burden of PCME prevention is compared with the burden of treatment. Prevention is much cheaper and less harmful than invasive treatments like periocular or intravitreal injections. Overall, both nepafenac 0.1% and nepafenac 0.3% are well tolerated. They should be used carefully in patients with compromised corneas such as those with severe dry eye or penetrating grafts. If otherwise healthy cataract patients have ≥2 risk factors, like PCME in the other eye or posterior capsule rupture during surgery, treatment should be considered. Once-daily nepafenac 0.3% dosing may improve postoperative outcomes through increased patient compliance and may reduce treatment burden further. Every patient should be assessed in terms of risks/benefits of the treatment, in individual basis, before cataract surgery.
