RESUMO
PURPOSE: To assess treatment response of Polypoidal choroidal vasculopathy (PCV) in a Caucasian population of British ethnicity with intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections alone and with a combination of anti-VEGF injections and photodynamic therapy (PDT). SETTING/VENUE: Department of Ophthalmology, University Hospital Southampton NHS Foundation Trust, United Kingdom. METHODS: Retrospective review of 95 Caucasian patients in a single centre with diagnosis of PCV between 2013 and 2018 were included. Best corrected visual acuity (BCVA), central retinal thickness (CRT), indocyanine green angiography (ICGA) characteristics, numbers and type of treatment were analysed at baseline and at 1 year. RESULTS: One hundred and one eyes included from 95 patients received either anti-VEGF injections (n = 79, 78.2%) alone or combination therapy with anti-VEGF and PDT (n = 6, 6%). A third untreated group was also observed (n = 16, 15.8%). Five eyes were excluded from the study due to structural retinal damage. Mean number of injections was 7.3 in the monotherapy group and 6.5 in the combination group. Both treatment groups showed improvement in BCVA at 1 year and this was statistically significant in the monotherapy group with a mean gain of 8.3 letters (p < 0.001). Mean CRT decreased in all treatment groups at twelve months and this change was significant (p < 0.01). In the observation group, vision and CRT remained stable. CONCLUSIONS: This study demonstrates significant improvements in BCVA at one year in our Caucasian cohort of British ethnicity with PCV in the treatment group.
RESUMO
PURPOSE: To report a case of anatomic closure and functional improvement in a patient affected by refractory full-thickness macular hole (FTMH) undergone a combined 41-gauge (g) surgically induced macular detachment and free internal limiting membrane (ILM) flap technique. METHODS: This is a retrospective case-report of a 70-years-olded woman affected by refractory FTMH who referred to Ophthalmology Unit of Guglielmo da Saliceto Hospital, Piacenza (Italy) in April 2023. The patient underwent a combined 41-g surgically induced macular detachment and free ILM flap. Macular detachment was induced by multiple subretinal injections of balanced salt solution (BSS) by 41-g needle through three retinotomies. Spectral-domain optical coherence tomography (SD-OCT) and best-corrected visual acuity (BCVA) were performed preoperatively and postoperatively at 7th day, 1st and 6th month. RESULTS: On 7th postoperative day, FTMH showed complete closure. BCVA improved from preoperative 20/400 to 20/70 at 6th postoperative month. DISCUSSION: BSS subretinal injection allowed the mobilization and relaxation of retina at the posterior pole. Although the edges of the hole were still detectable, their diameters were inferior to preoperative measurements. Autologous free ILM flap allowed to fill the residual gap into the hole. CONCLUSION: The final anatomic closure, and the postoperative functional improvement demonstrated the effectiveness of this approach, supporting its indication for refractory FTHM.
RESUMO
PURPOSE: To report the long-term anatomical and functional results of macular buckle for Myopic Traction Maculopathy (MTM) in stages 3a, 3b, 4a, and 4b according to the MTM Staging System (MSS). METHODS: Retrospective observational cohort study involving 55 consecutive patients with MTM in stages 3a, 3b, 4a, and 4b who underwent macular buckle (MB). Postoperative outcomes, including optical coherence tomography (OCT) scans to evaluate the MTM stage and its progression, were evaluated 1-month postoperatively (i.e., "intermediate follow-up") and at last follow-up ranging between 6 and 156 months postoperatively (i.e., "final follow-up"). RESULTS: Fifty-five eyes affected by MTM who underwent MB were enrolled. The mean preoperative and postoperative axial length was 31.13 ± 2.14 and 29.73 ± 2.16 mm, respectively (p < 0.01), with a mean axial shift of 1.32 ± 0.77 mm. The mean sample best corrected visual acuity (BCVA) at baseline, intermediate, and final follow-ups was 0.87 ± 0.36, 0.73 ± 0.31, 0.41 ± 0.32 logMar, respectively (p < 0.01). Foveal and retinal anatomical improvements were achieved in 50 (91%) and 53 (96.4%) eyes at intermediate follow-up, respectively. In the final follow-up, 54 (98.2%) and 55 (100%) eyes showed foveal and retinal anatomical improvements, respectively. CONCLUSIONS: MB as a single procedure, when applied to MTM in stages 3a, 3b, 4a, and 4b, leads to significant anatomical and functional improvement. The MTM Staging System allows us to evaluate the best surgical technique and the surgical timing tailored to the different stages to increase the surgery's success and lower the complications of each technique.
RESUMO
BACKGROUND: To evaluate the long-term anatomical and functional outcomes of anti-Vascular Endothelial Growth Factor intravitreal injections (anti-VEGF IVI) in patients with type 3 macular neovascularisation (MNV) in real-world settings. METHODS: Retrospective review of patients with type 3 MNV who received anti-VEGF IVI between 2013 and 2020. Primary outcomes were best corrected visual acuity (BCVA) and central macular thickness (CMT). Secondary outcome was the development of new-onset of foveal-involving geographic atrophy (GA) and disciform scars. RESULTS: We identified 59 eyes from 48 British patients that met the inclusion criteria. Treatment with anti- VEGF IVI resulted in a statistically significant reduction in median CMT, which was maintained throughout the study period. At 36 months, 24 eyes showed more than 50 µm reduction in CMT, 7 eyes remained stable and only 2 eyes showed an increase in CMT by more than 50µm compared to the baseline. At year three, deterioration was noticed in most eyes (52.78%) and vision remained stable or improved in 47.22% of the eyes. However, the median BCVA was not statistically significant different compared to baseline. During the study period new onset of macula-involving atrophy or scar was noted in 10.2% and 4.3% of the eyes, respectively. CONCLUSION: In this real-world study, anatomic and functional improvement were recorded 12-months post anti-VEGF IVI in type 3 MNV. Despite sustained anatomical improvement, vision returned back to baseline levels at 36-months. The development of GA and macular scar was only partially responsible for this outcome suggesting a more severe nature of this form of nAMD.

Purpose: to assess the tomographic retinal layers' thickness in eyes affected by branch retinal artery occlusion (BRAO) and to compare it to those of patients affected by primary open angle glaucoma (POAG). Methods: retrospective review of 27 patients; 16 with BRAO (16 eyes) and 11 with POAG (20 eyes) were identified among those who received SD-OCT scans, including analysis of macular retinal nerve fiber layer (mRNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer (INL), neuroretinal rim (NRR), circumpapillary RNFL at 3.5 mm and hemisphere asymmetry (HA). Results: the total IPL and INL thinning difference between the two groups was statistically significant (p = 0.0067 and p < 0.0001, respectively). The HA difference for the total macular thinning, mRNFL, GCL, IPL and INL (p < 0.0001) was also statistically significant. The analysis of the average total retinal thinning, total mRNFL and GCL thinning showed no statistically significant difference between the two groups. Conclusions: unilateral inner retinal thinning may represent a sign of temporal BRAO, particularly for INL thinning and HA difference over 17µm in total retinal layer thinning. This information is particularly useful in the diagnosis of previous, undiagnosed BRAO and may help prevent further retinal arterial occlusion and possible cerebrovascular incidents.
RESUMO
BACKGROUND: To descriptively report the advantages and the feasibility of microscope-integrated intraoperative optical coherence tomography (i-OCT) in managing different vitreoretinal diseases in a real-life setting. METHODS: We conducted an observational retrospective study involving 265 eyes that underwent elective retinal surgery and intraoperative OCT between 1 September 2018 and 1 October 2022 at Eyecare Clinic (Brescia, Italy). RESULTS: 52 epiretinal membranes, 30 retinal detachments, 60 high myopic eyes, 30 choroidal transplants, 40 macular holes, and 32 vitreo-proliferative retinopathies underwent vitreoretinal surgery and intraoperative OCT scans. The i-OCT was a useful diagnostic exam for all cases and significantly influenced our surgical management. CONCLUSIONS: i-OCT is a helpful surgical tool in ophthalmic surgery as it provides real-time feedback of tissue anatomy to surgeons, thereby guiding decision-making. Moreover, it provides additional information on the microarchitectural changes after instrument-tissue interactions, further guiding procedures when necessary and possibly reducing unessential surgical maneuvers.
RESUMO
SIGNIFICANCE: Spontaneous closure of an idiopathic full-thickness macular hole (FTMH) is a rare event. The underlying mechanisms are unclear because of the difficulty in detecting subtle structural changes even with serial imaging. Previous reports are largely optical coherence tomography (OCT) based, but multimodal imaging could highlight new information. PURPOSE: This study aimed to report the spontaneous closure of an idiopathic FTMH (iFTMH) and its recurrence and late closure documented by serial OCT integrated with multimodal imaging modalities and microperimetry (MP). CASE REPORT: A healthy 46-year-old man was referred to the Department of Ophthalmology of the University of Padova for an iFTMH in the right eye with preserved visual acuity. The patient was scheduled for monthly controls up to 12 months by an integrated assessment of OCT, angiography-OCT, short-wavelength fundus autofluorescence, and MP. Two months later, tracked OCT scans showed a closure of the hole with a residual lamellar macular hole. Sequential examinations revealed a discontinuation of photoreceptors (ellipsoid zone) and a recurrence of iFTMH, and 7 months later, iFTMH reclosed without any relevant changes up to 12 months. Foveal avascular zone area increased from the baseline reaching its maximum value when iFTMH recurred. Two hyper-fundus autofluorescence points were detected in the foveal area, one progressively decreased and one reached the most intense signal when iFTMH recurred. Retinal sensitivity decreased mostly in one hyper-fundus autofluorescence point when the ellipsoid zone line discontinued and reached the lowest value when iFTMH recurred, and increased mostly in the other points when iFTMH reclosed. CONCLUSIONS: Spontaneous iFTMH closure, as well as its recurrence and reclosure, is a rare event. By monitoring with multiple imaging modalities, MP and their overlaying elaboration can add new biomarkers with diagnostic and prognostic value.

BACKGROUND AND OBJECTIVE: The aim of this study was to evaluate the interobserver agreement of the myopic traction maculopathy (MTM) staging system (MSS). PATIENTS AND METHODS: Each observer was asked to look at the MSS Table and then identify, in each optical coherence tomography scan, one among four stages of MTM in the retina, one among three stages in the fovea, and, as secondary findings, the presence or absence of an outer lamellar macular hole and the presence or absence of epiretinal abnormalities. The interobserver agreement value was calculated using the Gwet's AC1 unweighted and AC2 weighted statistics. The outcomes were interpreted as poor (<0.00), slight (0.00 to 0.20), fair (0.21 to 0.40), moderate (0.41 to 0.60), substantial (0.61 to 0.80), or almost perfect (0.81 to 1.00) agreement. RESULTS: The agreement, among 65 participants, was 0.62 (AC1) and 0.77 (AC2) for the retina stage; 0.63 (AC1) and 0.81 (AC2) for the fovea stage; 0.56 (AC1) for the outer lamellar macular hole; and 0.26 (AC1) for epiretinal abnormalities. CONCLUSION: The MSS is highly reproducible and helps ophthalmologists to share information on MTM in a more accurate and reliable way. [Ophthalmic Surg Lasers Imaging Retina 2023;54(3):153-157.].

BACKGROUND: To evaluate the morbidity frequency measures in terms of the cumulative incidence of sympathetic ophthalmia (SO) triggered by single or multiple vitreoretinal (VR) surgery procedures in eyes without an antecedent history of trauma and previous ocular surgery, except for previous or concomitant uneventful lens extraction, and to further investigate the relationship between VR surgery and SO. METHODS: A literature search was conducted using PubMed, Embase, and Scopus from inception until 11 November 2022. The Joanna Briggs Institute (JBI) critical appraisal checklist for the case series and the Newcastle-Ottawa Scale were used to assess the risk of bias. The research was registered with the PROSPERO database (identifier, CRD42023397792). Meta-analyses were conducted using the measurement of risk and a 95% confidence interval (CI) for each study. RESULTS: A random-effect meta-analysis demonstrated that the pooled cumulative incidence of SO triggered by single or multiple VR surgery procedures in eyes without an antecedent history of trauma and previous ocular surgery, except for previous or concomitant uneventful lens extraction among patients who developed SO regardless of the main trigger, was equal to 0.14 with a CI between 0.08 and 0.21 (I2 = 78.25, z: 7.24, p < 0.01). The pooled cumulative incidence of SO triggered by single or multiple VR surgery procedures in eyes without an antecedent history of trauma and previous ocular surgery, except for previous or concomitant uneventful lens extraction among patients who underwent VR surgery, was equal to 0.03 for every 100 people, with a confidence interval (CI) between 0.02% and 0.004% (I2 = 27.77, z: 9.11, p = 0.25). CONCLUSIONS: Despite postsurgical SO being a rare entity, it is a sight-threatening disease. VR surgery should be viewed as a possible inciting event for SO and considered when counseling patients undergoing VR surgery.
RESUMO
BACKGROUND: To evaluate the incidence and risk factors for cystoid macular edema (CME) and epiretinal membrane (ERM) development after surgery for primary rhegmatogenous retinal detachment (RRD). METHODS: Retrospective observational cohort study involving 62 consecutive patients with primary RRD who underwent RRD repair with either scleral buckling (SB) or pars plana vitrectomy (PPV). SB was used in young phakic patients without posterior vitreous detachment (PVD), high myopic patients, and RRD associated with either anterior or inferior retinal tears. PPV was preferred over SB in pseudophakic patients or those with media opacity and posterior breaks that precluded the SB approach. After surgery, the macular changes, including CME and ERM development, were evaluated 3 and 6 months postoperatively. Phacoemulsification and intraocular lens (IOL) implantation were performed in phakic patients where media opacity or lens bulging did not allow the surgeon to perform surgical maneuvers. The inner limiting membrane (ILM) peeling was randomly performed in the macula-off and the macula-on RRD "pending foveal detachment" subgroup. RESULTS: Sixty-two eyes affected by RRD who underwent SB or PPV were enrolled. CME occurred in 33.3% of the PPV group regardless of the ERM formation. No CME cases were found in the SB group. Macula-off RRD increased the risk of CME by odds ratio (OR) = 4.3 times compared to macula-on RRD regardless of the surgical procedure (p = 0.04). Macula-off status increased the risk of CME of OR = 1.73 times compared to macula-on in the PPV subgroup (p = 0.4). Combined cataract surgery and PPV increased the risk of CME by OR = 3.3 times (p = 0.16) compared to PPV alone, and ILM peeling increased the risk of postoperative CME by OR = 1.8 times (p = 0.37). ERM occurred in 28% of patients who did not undergo ILM peeling, and 29.42% of those who underwent ILM peeling developed ERM (p = 0.6). CONCLUSIONS: The risk of postoperative CME was higher in patients with macula-off than in macula-on RRD and in those with macula-off RRD who underwent PPV. The SB would be advisable in patients with RRD sparing the macula. Furthermore, despite having several advantages, the combined phacoemulsification plus IOL implantation and PPV highly increased the risk of postoperative CME.

Surgical correction of traumatic aniridia aims to improve the quality of vision, compartmentalize the anterior and posterior chamber, and re-establish a satisfying cosmetic appearance. Various types of prosthetic iris devices (PIDs) are available, which differ in technical difficulty of implant and design: artificial iris (AI)-intraocular lens prosthesis, endocapsular capsular tension ring-based PID, and customized AI. The choice depends on the preexisting clinical condition after severe ocular trauma and on patient functional and cosmetic expectations. This systematic review of the literature compared anatomical and functional outcomes of various types of PIDs. Of 185 articles found in the literature, 70 fulfilled the eligibility criteria. 5 subgroups of PIDs were Ophtec, artificial iris from Ophtec BV, Morcher GmbH, HumanOptics AG, and other prosthesis. Both glare and aesthetic outcome improved postoperatively; in comparison with other PIDs, intraocular pressure rise was higher in the Morcher group (40%), whereas prosthesis dislocation was higher in the Ophtec group (39%).

OBJECTIVES: To evaluate the macular vascular flow in eyes with idiopathic macular pucker (EyeiMP), pre and post pars plana vitrectomy with epiretinal and limiting membranes peeling, and to compare it with the vascular flow in the healthy fellow eyes (Eyefellow), taken as physiological reference value. METHODS: 40 eyes of 40 patients were recruited. Best-corrected visual acuity (BCVA) was evaluated. Spectral domain optical coherence tomography (SD-OCT) and OCT-angiography parameters were central foveal thickness (CFT), choroidal thickness (CT), foveal avascular zone (FAZ) area, vessel area density (VAD), vessel length fraction (VLF), vessel density index (VDI) of superficial capillary plexus (SCP) and deep vascular complex (DVC), choriocapillaris (CC) flow. Absolute and relative difference calculation was applied to evaluate macular vascular flow in EyeiMP adjusted for physiological changes detected in Eyefellow. FOLLOW-UP: 6 months. RESULTS: BCVA improved (p = 0.003) in all cases following surgery. CFT reduced postoperatively (p = 0.0138). FAZ area was smaller in EyeiMP than Eyefellow (p = 0.0071) preoperatively and postoperatively it shrank further (p = 0.0027). After surgery, inverse correlation between FAZ area and BCVA was detected (r-0.683). VAD of SCP was pre- and post-operatively higher in EyeiMP than Eyefellow (baseline p = 0.0344, 6th month p = 0.0466). Relative difference of VDI of SCP (p = 0.0096) and CC flow (p = 0.0013) at 6 months reduced. DVC flow changed significantly only in Eyefellow. CT increased post-operatively in both EyeiMP (p = 0.0345) and Eyefellow (p = 0.00423), but relative difference did not change. CONCLUSIONS: Vascular flow indices monitoring demonstrated significant changes in both eyes: EyeiMP and Eyefellow. Relative difference of vascular flow provided objective estimate of changes due to iMP surgery taking into account physiological changes in Eyefellow.

PURPOSE: Outcomes of pneumatic retinopexy (PnR) using surgical microscope, wide-angle viewing system, and chandelier endoilluminator (microscope-assisted pneumatic retinopexy) for primary rhegmatogenous retinal detachment (RRD). METHODS: Retrospective study. 43 consecutive eyes with RRD undergoing microscope-assisted PnR surgery (MAPR) were analysed. Inclusion criteria comprehend phakic eyes with single retinal break or a group of breaks in detached retina in the same quadrant above 8- and 4-o'clock meridians. Follow-up was at least 6 months. RESULTS: Of the 43 eyes, a total of 25 (58%) presented preoperatively a single retinal break, 15 (35%) had two retinal breaks in the same quadrant and 3 (7%) presented three or more retinal breaks in the same quadrant. Other retinal breaks not observed preoperatively were discovered intraoperatively in 12 eyes (28%). In 9 (21%) the missed retinal breaks were in the same quadrant as the main diagnosed break(s), while 3 (7%) had missed retinal breaks in a different one. These 3 eyes as no longer adhering to the PnR indication criteria switched intraoperatively to other surgical procedures and were excluded in the reattachment rate results. The total primary reattachment rate with MAPR was achieved in 37 eyes (92.5%). No significant BCVA changes were observed postoperatively. CONCLUSION: MAPR is an effective and safe surgical option, it allows to work with both hands free and provides an adequate visualization of the retina during the procedure minimizing the risk of missed retinal breaks potentially leading to surgical failure.
RESUMO
This commentary describes steps in ocular reconstruction surgery following ocular globe injuries in both the anterior and posterior segment causing corneal opacity and aphakia. The authors propose to reorder the sequence of surgical manoeuvres during pars plana vitrectomy combined with keratoplasty and aphakia treatment without capsular support and highlight the advantages in the choice of the intraocular lens to implant. A mental outline of all surgical manoeuvres, being aware of the complications that can arise during surgery and knowing the long-term benefits of making more careful choices, can make this surgery more effective and safer.
RESUMO
PURPOSE: To analyse morpho-functional foveal changes in eyes with lamellar macular hole (LMH) by an integrated assessment of short-wavelength fundus autofluorescence (SW-FAF) and microperimetry (SW-FAF/microperimetry integrated assessment) before and after treatment with a technique of double-inverted flaps of epiretinal proliferation (EP) and internal limiting membrane (ILM). METHODS: Clinical and tomographic parameters were best-corrected visual acuity (BCVA), LMH size, central retinal thickness (CRT) and outer retinal layer integrity. SW-FAF/microperimetry integrated assessment allowed to analyse retinal sensitivity (RS) and FAF status of the fovea by an overlay of RS map on SW-FAF image. Follow-up was at baseline, 1, 3, 6 and 12 postoperative months. RESULTS: Forty pseudophakic eyes. Hyper-FAF area was associated with larger LMH size (p = 0.0073) and inversely correlated with CRT (p = 0.021). Lower preoperative RS was observed in hyper-FAF than normo-FAF areas (p = 0.0117). External limiting membrane (ELM) defect was associated with worse BCVA (p = 0.0004). After surgery, BCVA improved (p = 0.001) and it was related to ELM recovery (p = 0.00483), hyper-FAF area decreased (p = 0.001), and RS increased (p = 0.440). Hyper-FAF points that normalized their FAF were associated with higher RS improvement compared to unchanged points. CONCLUSION: Short-wavelength fundus autofluorescence/microperimetry integrated assessment provides important information on the entity of damage of LMH and on postoperative recovery. Double-inverted EP and ILM flap technique is safe and effective for LMH treatment.

AIM: The aim of this study is to evaluate the inter-observer and intra-observer agreement of the myopic traction maculopathy (MTM) staging system (MSS). METHODS: The agreement test for MSS was based on the evaluation of 104 optical coherence tomography (OCT) scans from 104 myopic eyes. According to the MSS, six observers were asked to identify, in each image, one among four retinal patterns and one among three foveal patterns of MTM, the presence of an outer lamellar macular hole (OLMH) and an epiretinal membrane (ERM). Each observer repeated the agreement test after a 60 days interval. RESULTS: Inter-observer reliability: the agreement of the test for the retina pattern was substantial (0.724), for the fovea pattern was 0.821, for the OLMH was 0.656, and for the ERM was 0.463. When all the criteria are included in the validation test the agreement was 0.657. Regarding the weighted statistics (Gwet's AC2, 95% CI), the validation test was statistically significant both when the variables were considered one by one, with an excellent agreement, respectively for the retina pattern (0.955) and the fovea pattern (0.963) and when all the variables were included in the tests (0.930). Intra-observer repeatability: all observers rerun the test after 2 months with a statistically significant percentage of confirmation of the previous test. CONCLUSION: The MSS offers in one Table information on diagnosis, natural history, function, prognosis, and management of MTM. The MSS is user-friendly and highly reproducible.

This review aims to collect the proposed surgical techniques for treating full thickness macular hole (FTMH) refractory to pars plana vitrectomy and internal limiting membrane (ILM) peeling and to analyse and compare anatomical and functional outcomes in order to evaluate their efficacy. The articles were grouped according to the surgical techniques used. Refractory FTMH closure rate and best-corrected visual acuity (BCVA) gain were the two analysed parameters. Thirty-six articles were selected. Ten surgical technique subgroups were defined: autologous platelet concentrate (APC); lens capsular flap transplantation (LCFT); autologous free ILM flap transplantation (free ILM flap); enlargement of ILM peeling, macular hole hydrodissection (MHH), autologous retinal graft (ARG), silicon oil (SO), human amniotic membrane (hAM), perifoveal relaxing retinotomy, arcuate temporal retinotomy. Refractory FTMH closure rate was similar among subgroups, not significant heterogeneity emerged (p = 0.176). BCVA gain showed a significant dependence on surgical technique (p < 0.0001), significant heterogeneity among subgroups emerged (p < 0.0001). Three sets of surgical technique subgroups with a homogeneous BCVA gain were defined: high BCVA gain (hAM); intermediate BCVA gain (APC, ARG, LCFT, MHH, SO); low BCVA gain (free ILM flap, enlargement of peeling, arcuate temporal retinotomy). In terms of visual recovery, the most efficient technique for treating refractory FTMH is hAM, lens capsular flap and APC that allow to obtain better functional outcomes than free ILM flap. MHH, ARG, perifoveal relaxing and arcuate temporal retinotomy require complex and unjustified surgical manoeuvres in view of the surgical alternatives with overlapping anatomical and functional results.

PURPOSE: To evaluate the postoperative effect on central retinal macular thickness of a cooled irrigating eye solution used during cataract surgery. PATIENTS AND METHODS: In this prospective, single-center study, 100 eyes of 50 patients (26 males and 24 females) were evaluated with spectral domain optical coherence tomography (SD-OCT) before and after phacoemulsification for senile cataract. Eyes were randomly divided into two groups based on the irrigating solution used during surgery: Group 1, 50 eyes received intraoperative irrigating solution at room temperature (~20.0±0.1°C); and Group 2, 50 fellow eyes received cold intraoperative irrigating solution (2.7±0.1°C). Changes in central macular thickness (CMT) were evaluated in both groups by SD-OCT macular raster scan for the nine Early Treatment of Diabetic Retinopathy Study (ETDRS) subfields and total macular volume, performed pre-surgery, and 1 and 4 weeks post-surgery. RESULTS: Despite there being no significant differences in variables between the two groups preoperatively, significant increases in CMT were observed at 1 week after surgery in both groups (p=0.02 and p=0.03, respectively), as well as in total macular volume (p<0.0001 and p=0.02, respectively). Inter-subgroup analysis showed a significant reduction in CMT (p=0.03) and total macular volume (p=0.001) at 1 week post-surgery in Group 2 compared to Group 1, whereas no significant differences were observed at 4 weeks. CONCLUSION: The use of a cooled irrigating eye solution during phacoemulsification may be beneficial in preventing the possible development of postoperative macular thickening. Further clinical studies may support this finding.
