[OPHTHALMOLOGY - ON THE TIP OF THE SPEAR].

INTRODUCTION: Ophthalmology is a broad branch of medicine, which includes an extensive range of sub-specialties on one hand, and interfaces with other fields of medicine on the other. This issue contains papers from different sub-specialties of ophthalmology, that together cover several of the most important issues in this field. These papers present the topics in a manner compatible with the wide readership of the journal, and touch upon the most current updates and innovations. The original articles in this issue deal with treatments for the prevention of myopia progression in children, treatment of complicated cases of retinal detachment in children, ocular manifestations of vascular abnormalities in patients with coronavirus, and a series of patients with corneal damage due to ultraviolet-C (UVC) lamps intended to clear the air of this virus. The review papers describe glaucoma and the current change in its treatment paradigm, which focuses on earlier intervention, ocular manifestations of systemic autoimmune diseases, and the possibilities for artificial corneal implantation. We hope that this special issue will be of interest and clinical value to its readers.

[LOWER EYELID BLEPHAROPLASTY].

INTRODUCTION: Eyelid blepharoplasty, including lower eyelid blepharoplasty, are among the most common aesthetic surgeries recently performed. In contrast to upper eyelid blepharoplasty, lower eyelid blepharoplasty is a surgery with mostly an aesthetic indication, in which patients bear all associated costs, and their expectations rise accordingly. Nevertheless, the complexity of the anatomy, the differences in the aging processes of the face and eyelids between patients, the diversity of surgical methods, and the expectations gap make the surgery more challenging in comparison to upper eyelid blepharoplasty. A comprehensive understanding of the eyelid anatomy and the surrounding tissues, as well as matching expectations alongside with thorough preoperative evaluation, are all essential for providing a more personal adjustment of the surgical method and avoiding complications and mental distress for both patients and surgeons. This article briefly reviews the anatomy and aging processes of the lower eyelids, the main surgical approaches, and their common complications. Moreover, we present a framework for how such complications can be avoided.

SYRINGE DESIGN AND FILLING TECHNIQUE AFFECT ACCURACY OF ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR INTRAVITREAL INJECTIONS.

PURPOSE: To evaluate the effect of syringe design and filling technique on the accuracy of anti-vascular endothelial growth factor delivery. METHODS: Volume output was measured with three syringe designs: a 1.0-mL slip-tip syringe, a 1.0-mL Luer-lock syringe, and a ranibizumab prefilled syringe-using two filling techniques ("upward" and "downward") and two fluids (water and bevacizumab). A total of 300 simulated injections were performed. Accuracy was determined by difference from the intended volume of 50 µ L and by mean absolute percentage error. RESULTS: Volume outputs were significantly different between syringe designs, with mean values of 61.99 ± 4.18 µ L with the 1-mL slip-tip syringe, 57.43 ± 4.95 µ L with the Luer-lock 1-mL syringe, and 51.06 ± 4.74 µ L with the ranibizumab syringe, making the latter the most accurate syringe. There were 37 cases (12.3%) of underdosing below 50 µ L, the majority of which occurred with the ranibizumab syringe. The "downward" technique reduced the occurrence of air bubbles. CONCLUSION: Intravitreal injections using 1.0-mL syringes are less accurate than using the ranibizumab prefilled syringe, which has a low-volume and low dead-space plunger design. The variability in volume output may result in less predictable treatment response, especially in cases of underdosing, which were more common with the ranibizumab syringe.

The 100 most cited papers on amblyopia: a bibliographic perspective.

AIM: To analyze the top 100 most cited papers related to amblyopia. METHODS: A bibliographic search in the Institute for Scientific Information Web of Knowledge across 55 years was performed. RESULTS: Eighty-nine of the 100 papers were published in first-quartile journals. Half (50) of the senior authors were from the USA. Most papers dealt with clinical science (72) and included original research (84). Forty-two of the articles related to all three types of amblyopia (refractive, strabismic and deprivation). Thirty-four related to both strabismic and refractive amblyopia. Around two-thirds of the papers dealt with treatment (34) and pathophysiology (30). Almost a quarter (23%) of the papers were multicenter studies. Nearly half (48) of the papers were published between 2000 and 2010. The Pediatric Eye Disease Investigator Group (PEDIG) published the highest number of studies (11), which dealt more with treatment (p = 0.01) and had higher average number of citations per years (p = 0.05). A larger number of articles on the treatment of amblyopia are newer (p = 0.01). There was no correlation between the time of their publication and the number of citations (p = 0.68, r = 0.042). CONCLUSIONS: Half of the papers were published between 2000 and 2010 and were spearheaded by PEDIG. Most papers dealt with treatment and pathophysiology. This study provides an important historical perspective, emphasizing the need for additional research to better understand this preventable and curable childhood vision impairment.

The Effect of Syringe-Filling Technique on the Risk for Endophthalmitis after Intravitreal Injection of Anti-VEGF Agents.

PURPOSE: This study aimed to compare the risk for post-injection endophthalmitis between different anti-vascular endothelial growth factor (VEGF) agents and syringe preparation techniques. METHODS: A retrospective study of anti-VEGF injections performed in 3 large ophthalmology departments between 2013 and 2019 was conducted. Injections were categorized according to the drug and the syringe-filling technique - prefilling by a hospital pharmacy, prefilling by a good manufacturing practice (GMP) pharmacy, self-drawing from the vial by the injecting physician, and use of a prefilled syringe. Cases of endophthalmitis were identified, and their rates were analyzed. RESULTS: A total of 197,402 injections were included, and 53 cases of endophthalmitis were identified (0.027% risk). The risk of endophthalmitis following injections with syringes that were prefilled by GMP pharmacies or the manufacturers was significantly lower than that following injections which were self-drawn by the physician (0.019% vs. 0.055%, p < 0.0001). For ranibizumab, risk of endophthalmitis decreased since it became available in a prefilled syringe (0.054% vs. 0.014%, p = 0.066), bordering on statistical significance. CONCLUSIONS: The syringe-filling technique is an important factor determining risk of post-injection endophthalmitis. Use of GMP-grade prefilling by professional pharmacies or the manufacturers significantly reduces this risk and should be the technique of choice for all drugs administered by intravitreal injection.

Optical Coherence Tomography Biomarkers Predicting Visual Acuity Change after Intravitreal Bevacizumab Injections for Macular Edema Secondary to Branch Retinal Vein Occlusion.

PURPOSE: This study aimed to identify baseline optical coherence tomography (OCT) factors in branch retinal vein occlusion (BRVO) that predict response to bevacizumab injections. METHODS: It is a retrospective case series of consecutive patients that underwent OCT at diagnosis, and the central macular thickness (CMT), extent of disorganized retinal inner layers, and outer retinal layers including external limiting membrane, ellipsoid zone (EZ), and cone outer segment tips (COST) were measured. Patients received 3 consecutive monthly injections of bevacizumab followed by pro re nata treatment. The main outcome measure was improvement in best-corrected visual acuity (BCVA) after 1 year. Results are expressed as mean ± SD, and p value <0.05 was considered statistically significant. RESULTS: Overall, 66 eyes of 66 patients, with an average age of 68.5 ± 11.4 years, were included. The mean BCVA improved significantly from 0.68 logMAR at baseline to 0.50 logMAR at 1 year (p < 0.001). Baseline logMAR BCVA (r = 0.41, p < 0.001) and CMT (r = 0.23, p = 0.04) were associated with improvement while EZ (r = -0.24, p = 0.05) and COST (r = -0.32, p = 0.01) disruption with deterioration in BCVA. CONCLUSION: In patients with naïve BRVO treated with bevacizumab, BCVA improvement at 1 year can be predicted from baseline BCVA, CMT, extent of COST disruption, and EZ disruption.

Optical Coherence Tomography Prognostic Factors in Age-Related Macular Degeneration Patients with Peripapillary Choroidal Neovascularization.

PURPOSE: The aim of the study was to investigate the correlation between optical coherence tomography (OCT) findings and visual acuity outcomes after treatment with intravitreal bevacizumab (IVB) injections for age-related macular degeneration (AMD) patients with peripapillary choroidal neovascularization (PPCNV). METHODS: The study involved a retrospective case series of consecutive patients diagnosed with PPCNV secondary to AMD. All patients were treated with IVB injections with a follow-up time of 1 year. Data collected included best-corrected visual acuity (BCVA) and automated and manually measured OCT parameters. RESULTS: A total of 68 eyes were diagnosed with PPMV. Of them, 30 eyes of 30 patients aged 84.3 ± 6.9 years of which 63.3% female gender were included. Baseline BCVA was 0.46 ± 0.62 logMAR (Snellen 20/57), average choroidal thickness was 193.2 ± 22 µm, and mean number of IVB injections was 7.2 ± 1.9. After 1 year, BCVA was 0.56 ± 0.78 logMAR (Snellen 20/72) (p = 0.28). Eyes with greater central retinal thickness (r = -0.36, p = 0.05), greater subretinal hyper-reflective material (SHRM) area (r = -0.37, p = 0.05), and greater sub-retinal fluid (SRF) area (r = -0.73, p < 0.001) had a significantly smaller improvement in BCVA. Eyes with pigment epithelium detachment (PED) (0.68 ± 0.90 vs. 0.21 ± 0.12, p = 0.03) had a significantly worse BCVA. CONCLUSIONS: Our data suggest that AMD-related PPCNV with greater foveal thickness, PED size, SHRM, and SRF areas have worse final BCVA prognosis.

Intravitreal air bubbles following intravitreal injections: a comprehensive analysis.

PURPOSE: To evaluate the prevalence of residual air bubbles following intravitreal injections of anti-VEGF agents, and to compare two techniques designed to reduce their occurrence. METHODS: Patients who received intravitreal injections reported the presence of air bubbles following the procedure, and were followed to determine when they disappeared. Two techniques used to reduce air bubbles prior to injection were compared-tapping the syringe with the needle up ("upwards" technique) or down ("downwards" technique). Rates of residual air bubbles were compared between techniques, and between different drugs. RESULTS: The study included 344 intravitreal injections, 172 injected with each technique. The overall rate of residual air bubbles was 11.3%, with 94.9% resolution by 48 h. The rate was significantly lower with the "downwards" technique (7.5% vs. 15.1%, p = 0.027). It was also significantly lower with ranibizumab injected using pre-filled syringes than with bevacizumab and aflibercept (0% vs. 12.1% and 14.7%, p < 0.0001). A questionnaire revealed patients reported medium levels of discomfort and a high importance of avoiding air bubbles. CONCLUSIONS: Residual air bubbles are a common occurrence, likely to be experienced by most patients undergoing repeated injections. This phenomenon may be significantly reduced by using the described "downwards" technique, or pre-filled syringes.

FULL-THICKNESS MACULAR HOLE IN AGE-RELATED MACULAR DEGENERATION PATIENTS WITH TWO DISTINCT ENTITIES: A Multicenter Study.

PURPOSE: To describe optical coherence tomography characteristics of full-thickness macular holes (FTMHs) in age-related macular degeneration patients. METHODS: A multicenter, retrospective, observational case series of patients diagnosed with age-related macular degeneration and FTMHs seen between January 1, 2009, and January 3, 2020. Clinical charts and spectral-domain optical coherence tomography images were reviewed. Optical coherence tomography findings included FTMH-inverted trapezoid or hourglass appearance, central macular thickness (CMT), complete retinal pigment epithelium and complete retinal outer retinal atrophy, and presence of pigment epithelium detachment and epiretinal membrane. The mean outcome was the morphologic and functional characterization of different subtypes of FTMHs. RESULTS: A total of 86 eyes of 85 consecutive patients, with mean age of 80.31 ± 8.06 and mean best-corrected visual acuity of 1.17 ± 0.58 logarithm of the minimal angle of resolution. Two different subtypes of FTMHs were identified: tractional and degenerative. Fifty (58%) degenerative FTMHs characterized with inverted trapezoid appearance and 36 (42%) tractional FTMHs characterized with hourglass appearance. Degenerative FTMHs presented with 66% of CMT < 240 µm, 14% of CMT > 320, and 70% of complete retinal outer retinal atrophy, in comparison with 41% of CMT < 240 µm, 42.9% of CMT > 320%, and 20% of complete retinal outer retinal atrophy in the tractional FTMH group (P = 0.002, 0.003, <0.001, respectively). The presence of epiretinal membrane and pigment epithelium detachment where significantly higher in tractional FTMHs (P = 0.02, 0.03, respectively). CONCLUSION: Degenerative and tractional FTMHs may be two distinct clinical entities. Discerning degenerative from tractional FTMHs is possible by using optical coherence tomography features including shape of the FTMHs, CMT, internal-external ratio of FTMHs, and presence of complete retinal outer retinal atrophy, pigment epithelium detachment, and epiretinal membrane.

Evaluation of Accuracy and Agreement of Optical Coherence Tomography Angiography Interpretation of Common Retinal Findings and Diagnoses.

PURPOSE: To evaluate the accuracy and agreement of optical coherence tomography angiography (OCTA) interpretation in cases of common retinal findings and diagnoses, and to evaluate the effect of OCT B-scans on OCTA interpretations. METHODS: This is a case series consisting of a questionnaire with 8 cases demonstrating common retinal conditions of normal, age-related macular degeneration (AMD) and diabetic retinopathy (DR). Each case included OCTA images, and 58 participants were asked to identify retinal findings and provide a diagnosis. Following OCTA interpretation, the corresponding OCT B-scans were revealed and the participants were asked again to identify retinal findings and provide a diagnosis. The rates of accuracy and agreement for each condition were analyzed. RESULTS: Overall the rates of accurate diagnosis and identification of retinal findings were 37.4 and 61.6%, respectively. Following addition of the OCT B-scans, the rates increased to 61.6 and 79.4%, respectively (p < 0.001 for both). A significant improvement in correct interpretation occurred in the normal and AMD cases, but not in the DR cases. There was no correlation with length of experience or self-reported familiarity with OCTA. DISCUSSION: Considerable variability exists in OCTA interpretation, with mediocre rates of accuracy and agreement between clinicians. Increased familiarity as well as future automation advances will be needed to improve OCTA interpretation accuracy and uniformity.

Neovascular age-related macular degeneration presenting at extremities of age: a comparative study.

PURPOSE: To compare the characteristics and response to treatment between patients with NVAMD presenting at the extremities of the AMD age spectrum. METHODS: Fifty-four eyes of 47 patients were included in this retrospective study, divided by age at NVAMD presentation under 65 (n = 15) or over 85 (n = 39) years. All patients were initially treated with 3 monthly bevacizumab injections, followed by a PRN protocol. Clinical parameters and OCT characteristics were recorded and analyzed at presentation, after the initial 3 monthly injections and at 1 year. RESULTS: At presentation, patients in the young group had significantly higher rates of subretinal fluid (p = 0.005), a polypoidal choroidal vasculopathy-like pattern (p < 0.01) and a history of smoking (p = 0.004). Submacular hemorrhage and pigment epithelial detachments were more common in young patients, and intraretinal fluid was more common in elderly patients (all with borderline statistical significance). VA improved significantly more in the younger patients at 3 months and 1 year (p = 0.001 and 0.002, respectively), despite similar treatment protocols and mean number of injections. Bilateral involvement at baseline was more common in elderly patients (p = 0.008). The differences in OCT characteristics between groups remained throughout the study period. CONCLUSION: There are considerable differences in the clinical manifestations and response to treatment between NVAMD patients at the extremities of the AMD age spectrum. Different pathophysiological, systemic, and genetic factors may play a role in such patients.

EVALUATION OF ACCURACY AND UNIFORMITY OF THE NOMENCLATURE OF VITREORETINAL INTERFACE DISORDERS.

PURPOSE: To evaluate the accuracy and uniformity of the definitions used to diagnose vitreoretinal (VR) interface disorders and to assess it after review of its definitions. METHODS: A case-series study, consisting of a questionnaire of 46 optical coherence tomography images of six VR interface disorders: vitreomacular adhesion, vitreomacular traction, epiretinal membrane, full-thickness macular hole, lamellar macular hole, and pseudohole. Images were presented to 41 practicing ophthalmologists (13 residents, 11 VR specialists, and 17 non-VR specialists), and a diagnosis was recorded for each image. The questionnaire was repeated after review of the International Vitreomacular Traction Study (IVTS) group classification. Rates of accuracy and uniformity for each condition were analyzed. RESULTS: Overall correct identification rates according to the IVTS classification were achieved in 67.4% of cases and were highest for epiretinal membrane and full-thickness macular hole, followed by vitreomacular adhesion, vitreomacular traction, and lamellar macular hole, and were significantly lower for pseudohole (P < 0.001). Accuracy was higher among VR specialists and was associated with previous familiarity with the IVTS classification (P = 0.043) but not with length of experience in ophthalmology (P = 0.74). After review of the IVTS classification, overall correct identification rates improved to 71.7% (P = 0.004), with the significant improvement in pseudohole identification (P = 0.002). CONCLUSION: The IVTS classification is effective in standardizing the diagnosis of VR interface disorders. It is expected to become increasingly assimilated among ophthalmologists over time, leading to higher rates of accuracy and uniformity in diagnosing VR interface disorders.

OUTCOMES OF RHEGMATOGENOUS RETINAL DETACHMENT REPAIR AFTER FAILED PNEUMATIC RETINOPEXY.

PURPOSE: To evaluate the visual and anatomical outcomes of reoperations following failure of pneumatic retinopexy (PR) for rhegmatogenous retinal detachment repair and compare the different surgical techniques used in these cases. METHODS: The study included 114 eyes of 114 patients who underwent PR for rhegmatogenous retinal detachment and required subsequent surgery for its repair. These included repeated PR, scleral buckling, vitrectomy with gas or silicone oil, and vitrectomy with scleral buckling. The groups were compared for rates of retinal reattachment, visual improvement, and the occurrence of recurrent rhegmatogenous retinal detachment and any other postoperative complications. RESULTS: In 91 (79.8%) eyes, the retina was reattached with one additional procedure. The success rate was significantly lower in eyes treated by repeated PR than by other surgical techniques (33 vs. 76-90%; P < 0.001). Visual acuity after PR failure was not significantly different than that at presentation and had improved significantly after surgery for retinal reattachment (P < 0.001). CONCLUSION: Pneumatic retinopexy failure was not associated with visual acuity loss, and the outcomes in 79.2% of cases that required only one additional surgery are comparable with those achieved with primary surgery. Poor outcomes were associated with eyes that required more than one additional surgery and that suffered complications.

Outcomes following Laser Retinopexy for Retinal Tears: A Comparative Study between Trainees and Specialists.

OBJECTIVE: To compare the outcomes of laser retinopexy for the treatment of retinal tears between residents and specialists, and to identify tear characteristics associated with the risk of progression to retinal detachment (RD). METHODS: A retrospective review of 307 eyes treated by laser retinopexy, categorized by the performing physician, either a resident (217 cases) or a specialist (90 cases). Recorded parameters included the number, size, and location of the retinal tears, the presence of bridging vessels, vitreous hemorrhage (VH), or subretinal fluid (SRF), the need for additional laser, progression to RD, and surgery. RESULTS: Additional laser was performed in 42.3% of cases in the resident group and 35.5% in the specialist group (p = 0.26). Progression to RD occurred in 6.9% of cases in the resident group and 5.5% in the specialist group (p = 0.66). The presence of VH and SRF were associated with an increased risk of progression to RD (p < 0.0001 and 0.003, respectively). A higher proportion of cases with SRF were treated by specialists (p = 0.006). CONCLUSIONS: Laser retinopexy is safely and effectively performed by residents, with no worse outcomes than procedures performed by specialists. A high rate of additional laser may be needed to achieve RD prophylaxis, and higher-risk cases can be identified at presentation and then referred to specialists.

ACCURACY AND PRECISION OF INTRAVITREAL INJECTIONS OF ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR AGENTS IN REAL LIFE: What Is Actually in the Syringe?

PURPOSE: To evaluate the accuracy and precision of anti-vascular endothelial growth factor volume delivery by intravitreal injections in the clinical setup. METHODS: Volume output was measured in 669 intravitreal injections administered to patients, calculated from the difference in syringe weight before and after expelling the drug. Three groups were included: prefilled bevacizumab 1.0 mL syringe (Group 1, n = 432), pre-filled ranibizumab in a small-volume syringe with low dead-space plunger design (Group 2, n = 125), and aflibercept drawn and injected using a 1.0-mL syringe (Group 3, n = 112). Accuracy was analyzed by mean absolute percentage error, and precision by coefficient of variation. RESULTS: Volume outputs in all 3 groups were significantly different from the target of 50 µL (P < 0.0001 for all), and mean absolute percentage error values were 12.25% ± 5.92% in Group 1, 13.60% ± 8.75% in Group 2, and 24.69% ± 14.84% in Group 3. No difference was found between groups 1 and 2, but both were significantly more accurate than Group 3 (P < 0.0001 for both). CONCLUSION: The current practices used for intravitreal injections are highly variable, with overdelivery of the anti-vascular endothelial growth factor drugs measured in most cases, but underdelivery in 16.3% of injections. Use of a prefilled syringe was associated with improved accuracy, and low dead-space plunger design may improve precision.

[INTRAVITREAL INJECTION - A SMALL PROCEDURE FOR THE EYE, A GIANT LEAP FOR OPHTHALMOLOGY].

INTRODUCTION: Intravitreal injections are the most common therapeutic procedures in ophthalmology. These injections allow intraocular delivery of drugs that are highly effective for the treatment of a variety of retinal diseases. The procedure is short and simple, has an excellent local and systemic safety profile, and enables restoration and preservation of visual acuity in a large number of patients. Intravitreal injections were introduced to the routine clinical practice of ophthalmology only a little over a decade ago, but have created a therapeutic revolution due to their high efficacy, and today are an integral part of the treatment of ocular diseases. This review will cover the development of intravitreal injection treatment, describe the injected drugs, the injection technique and its possible complications, and the commonly used treatment protocols.

FIVE-YEAR FOLLOW-UP AFTER EPIRETINAL MEMBRANE SURGERY: A Single-Center Experience.

PURPOSE: To evaluate the rate of epiretinal membrane (ERM) recurrence in eyes that underwent ERM peeling surgery at least 5 years earlier. METHODS: Retrospective interventional case series study of 37 patients (15 women and 22 men; mean age, 70 ± 7.6 years) operated on for ERM removal with a follow-up of at least 5 years. The patients underwent testing for visual acuity, an ophthalmic examination, and optical coherence tomography imaging, all of which were assessed preoperatively, postoperatively, and at the 5-year follow-up. RESULTS: Visual acuity significantly improved at 1 year after peeling compared with baseline (P = 0.045), and the improved results were maintained at 5 years (P = 0.804) 0.766 logarithm of the minimum angle of resolution (Snellen 6/35). The central macular thickness decreased significantly at the 1-year follow-up compared with baseline and continued to decrease as measured at the 5-year follow-up (P = 0.04). At 5 years, the ERM recurrence rate reached 58% (28% extrafoveal). Photoreceptor atrophy and retinal pigment epithelium changes correlated with diabetes mellitus (P = 0.028). CONCLUSION: The recurrence rate of ERM after peeling surgery was reported as being around 5% to 12%. It was 58% in the current study. Because the recurrent ERM is generally mild, visual acuity was unaffected.

2018 Update on Intravitreal Injections: Euretina Expert Consensus Recommendations.

Intravitreal injections (IVI) have become the most common intraocular procedure worldwide with increasing numbers every year. The article presents the most up-to-date review on IVI epidemiology and techniques. Unfortunately, important issues related to pre-, peri- and postinjection management lack randomized clinical trials for a final conclusion. Also, a great diversity of approaches exists worldwide. Therefore, expert consensus recommendations on IVI techniques are provided.

Management of Diabetic Macular Edema.

Diabetic macular edema is a common condition frequently encountered by ophthalmologists. In this piece we briefly review its definition, pathogenesis, clinical aspects, imaging, and treatment.

Comparison of retinal detachment surgery outcome among patients undergoing pars plana vitrectomy with and without relaxing retinotomy.

The purpose of this four year retrospective study was to compare the anatomical and functional outcomes of complicated retinal detachment (RD) surgery by pars plana vitrectomy (PPV) with and without retinotomy. The main outcome measures were primary anatomical success (defined as retinal re-attachment at the final follow-up after a single operation, with or without silicone in situ), final anatomical success, final best-corrected visual acuity (BCVA) and postoperative complications. Baseline characteristics did not differ between the groups, although there was a borderline significant trend for the retinotomy group to be associated with worse pre-surgical ocular pathology. With a mean follow-up of 18 (± 7.8) months, primary anatomical success was achieved in 76.7% (33 of 43) of the retinotomy group eyes vs. 67.8% (40 of 59) of the eyes in the group without retinotomy. Final anatomical success rates for the retinotomy group and no retinotomy group were 100 and 93.2% respectively. The final BCVA was 1.57 LogMAR with retinotomy and 1.38 without retinotomy, an improvement in both groups. The incidence of postoperative complications was similar in the two groups, while the frequency of macular holes was higher in the retinotomy group. A similar degree of improvement in BCVA following both surgeries indicates their similar efficacy and justifies their performance even in complicated eyes in order to improve the patients' quality of life. With neither approach superior to the other, the choice of method should be left to the surgeon.
