RESUMO
PURPOSE: Analyze the peripheral vitreoretinal interface with widefield optical coherence tomography. METHODS: Retrospective chart analysis and widefield optical coherence tomography in 120 consecutive cases of rhegmatogenous pathology. RESULTS: There were 166 lesions in 120 eyes, including 106 horseshoe tears, 22 operculated holes, 30 nonoperculated holes, six giant tears, and two peripheral lamellar defects followed for 6.1 ± 1.2 months. Posterior vitreous detachment was present in all eyes (101/101, 100%) with tears and operculated holes, but only in 5/19 eyes (26.3%) with nonoperculated holes ( P < 0.001). Axial vitreous traction was evident at the anterior edge of horseshoe tears (106/106, 100%), but not the posterior border (18/106, 17%, P < 0.001). Operculated holes located posterior to the vitreous base were free from vitreous traction, displaying a morphology similar to the macular hole. Nonoperculated holes were farther anterior with signs of tangential traction in 23/30 (76.7%) cases. Peripheral vitreoschisis was more often associated with nonoperculated holes (25/30, 83.3%), than horseshoe tears (17/106, 16%; P < 0.001). Horseshoe tears and nonoperculated holes were more often associated with retinal detachment (58/106 [54.7%] and 15/30 [50%], respectively) than operculated holes (5/22, 22.7%), P = 0.023. CONCLUSION: Peripheral vitreoretinal interactions are similar to vitreomaculopathies, with axial and vitreoschisis-related tangential traction playing different roles in different rhegmatogenous pathologies. Peripheral optical coherence tomography improves understanding of pathophysiology and risks of retinal detachment.

PURPOSE: To evaluate the structural characteristics and long-term visual outcomes in eyes impacted by macular edema as a consequence of retinal vein occlusion that has undergone effective treatment with anti-vascular endothelial growth factor therapy. METHODS: Inclusion criteria comprised 42 eyes of 41 patients, subjected to long-term follow-up, displaying resolved macular edema after a minimum of 5 years since the commencement of anti-vascular endothelial growth factor therapy. During the final visit, two experienced observers evaluated several qualitative parameters using spectral-domain optical coherence tomography, such as the integrity of the external limiting membrane, the state of the ellipsoid zone and retinal pigment epithelium, and the presence of disorganization of the retinal inner layers. In addition, a quantitative evaluation of the inner and outer retinal thicknesses was conducted for the purpose of topographical analysis. RESULTS: The most prominent qualitative correlation identified with best-corrected visual acuity during the final visit was connected to the presence of disorganization of the retinal inner layers ( P = 0.004) and the integrity of the external limiting membrane ( P = 0.015). In relation to quantitative aspects, a noteworthy correlation was noted between the visual acuity during the last visit and the parafoveal thickness in both the inner ( P = 0.003) and outer retina ( P = 0.018). CONCLUSION: In eyes where macular edema resulting from retinal vein occlusion has been successfully resolved with anti-vascular endothelial growth factor therapy, changes in the status of the external limiting membrane and the presence of disorganization of the retinal inner layers serve as valuable optical coherence tomography biomarkers, indicating prolonged visual outcomes.

BACKGROUND: to analyze, at one year, the efficacy and safety of treat-and-extend (T&E) intravitreal (IV) Brolucizumab in patients affected by macular neovascularization (MNV). Both naïve and previously treated (i.e., switched) patients were included, and the data from the two groups were compared. METHODS: anatomical (i.e., central subfoveal thickness, CST; presence of fluid), functional (i.e., best corrected visual acuity, BCVA) and treatment-related (i.e., number of IV injections within the study period; number of patients reaching a 12-weeks interval between treatments) data from 41 eyes of 41 subjects (20 naïve and 21 switched) were analyzed. Patients were treated with 3 monthly IV injections followed by a T&E regimen based on a disease activity assessment performed at each scheduled IV treatment. RESULTS: significant CST reduction (from 412.1 ± 115.8 to 273.2 ± 61.6; p < 0.05) and BCVA (mean; p) improvement were observed in the naïve group, while in the switched cohort, both parameters were almost stable. In the naïve and switched groups, 55% and 33.5% of patients, respectively, reached a 12-week IV interval at one year, with a mean of 6.55 ± 1 and 7.43 ± 0.68 IV treatments, respectively. One patient with mild anterior uveitis without sequelae was recorded. CONCLUSION: In patients with MNV, IV Brolucizumab injections following a T&E regimen demonstrated great efficacy and a good safety profile, with greater anatomical and functional results in naïve patients. TRIAL REGISTRATION: This study was approved by the Local Ethics Committee (protocol number 155/2020, general registry number n°11486, InterHospital Ethics Committee, San Luigi Gonzaga Hospital, Orbassano, Italy).

Purpose: We report the successful surgical treatment of a case of spontaneous complete anterior crystalline lens luxation in a patient affected by retinitis pigmentosa (RP), associated with elevated intraocular pressure and pupillary block. Additionally, we review the current literature regarding the association between ectopia lentis and RP. Case description: A 44-year-old female RP patient presented to our emergency department reporting severe ocular pain in her left eye (LE) and sickness. She had no history of ocular trauma and did not report systemic disorders. The best corrected visual acuity at presentation was 1/20 in her LE, the intraocular pressure was 60 mmHg, and slit lamp examination showed in her LE a complete dislocation of the lens in the anterior chamber, with mydriasis, atalamia, and a pupillary block. The patient had been administered intravenous mannitol 18% solution and dorzolamide-timolol eye drops and was hospitalized for urgent lens extraction. Anterior segment optical coherence tomography and ultrasound biomicroscopy were performed before surgery. Decompressive 23-gauge pars plana vitrectomy and phacoemulsification were performed, and the capsular bag was removed due to marked zonular weakness, with deferred intraocular lens implant. Conclusions: Acute angle closure glaucoma in patients with RP may be rarely caused by spontaneous anterior lens dislocation. To our knowledge, this is the first report of spontaneous anterior lens dislocation in an RP patient, documented through photographs, anterior segment optical coherence tomography, and ultrasound biomicroscopy.

PURPOSE: To predict improvement of best-corrected visual acuity (BCVA) 1 year after pars plana vitrectomy for epiretinal membrane (ERM) using artificial intelligence methods on optical coherence tomography B-scan images. METHODS: Four hundred and eleven (411) patients with Stage II ERM were divided in a group improvement (IM) (≥15 ETDRS letters of VA recovery) and a group no improvement (N-IM) (<15 letters) according to 1-year VA improvement after 25-G pars plana vitrectomy with internal limiting membrane peeling. Primary outcome was the creation of a deep learning classifier (DLC) based on optical coherence tomography B-scan images for prediction. Secondary outcome was assessment of the influence of various clinical and imaging predictors on BCVA improvement. Inception-ResNet-V2 was trained using standard augmentation techniques. Testing was performed on an external data set. For secondary outcome, B-scan acquisitions were analyzed by graders both before and after fibrillary change processing enhancement. RESULTS: The overall performance of the DLC showed a sensitivity of 87.3% and a specificity of 86.2%. Regression analysis showed a difference in preoperative images prevalence of ectopic inner foveal layer, foveal detachment, ellipsoid zone interruption, cotton wool sign, unprocessed fibrillary changes (odds ratio = 2.75 [confidence interval: 2.49-2.96]), and processed fibrillary changes (odds ratio = 5.42 [confidence interval: 4.81-6.08]), whereas preoperative BCVA and central macular thickness did not differ between groups. CONCLUSION: The DLC showed high performances in predicting 1-year visual outcome in ERM surgery patients. Fibrillary changes should also be considered as relevant predictors.

PURPOSE: To compare macular atrophy (MA) secondary to age-related macular degeneration (AMD) and Stargardt disease (STGD) using the choroidal vascularity index (CVI). METHODS: In this multicentric retrospective study, two distinct cohorts were collected: patients with MA secondary to AMD and MA secondary to STGD. All patients were investigated using a multimodal imaging approach, including CVI in the subfoveal 1000 µm area. Of note, the CVI is not influenced by aging, which allows comparisons between different cohorts. RESULTS: Seventy eyes were included: 35 eyes of 35 patients (mean age 78 ± 7 years) in the AMD group and 35 eyes of 35 patients (mean age 41 ± 16 years, p < 0.001) in the STGD group. Choroidal thickness was significantly lower in the AMD group in comparison to the STGD group (151 ± 80 µm vs 353 ± 105 µm, p < 0.001). The total choroidal area (TCA) was significantly greater in the STGD group in comparison to the AMD group (1.734 ± 0.958 mm2 vs 0.538 ± 0.391 mm2, respectively, p < 0.001). Interestingly, the CVI was significantly lower in AMD patients in comparison to STGD patients (27.322 ± 15.320% vs 49.880 ± 7.217%, respectively, p < 0.001), and this difference was confirmed in the subgroup of patients over 50 years old. CONCLUSION: Our results corroborate the hypothesis that large choroidal vessels were impaired to a greater extent in AMD than in STGD. CVI may help in differentiating AMD from STGD in the presence of MA, better understanding of the pathogenesis, and monitoring of therapeutic response.

BACKGROUND/PURPOSE: To determinate the efficacy of the human amniotic membrane plugs with sulfur hexafluoride versus human amniotic membrane plug with air as endotamponade to treat macular holes that failed to close after vitrectomy plus internal limiting membrane peeling. Multimodal imaging was focused to evaluate preoperative features and postoperative changes. METHODS: Prospective interventional comparative study. Twenty eyes of 20 patients affected with macular hole that failed to close were divided into 2 groups: 10 eyes received an amniotic membrane plug with 20% sulfur hexafluoride tamponade and 10 eyes received an amniotic membrane plug with air tamponade. All eyes were studied using multimodal advanced diagnostic tools, such as spectral-domain optical coherence tomography, optical coherence tomography angiography, microperimetry, and adaptive optics to investigate the postoperative results. RESULTS: In both groups, all macular holes were found successfully closed after 12 months. Mean preoperative best-corrected visual acuity was 20/400 in the SF6 group and 20/250 in air group. Final mean best-corrected visual acuity was 20/63 in both groups. The superficial capillary plexus, studied using optical coherence tomography angiography, showed a statistically significant difference between the treated and the fellow eyes. Adaptive optics images revealed the presence of a photoreceptor cell mosaic in the area of the amniotic membrane plug. CONCLUSION: The human amniotic membrane combined with air endotamponade demonstrated its effectiveness to seal macular holes that failed to close after vitrectomy plus internal limiting membrane peeling. Advanced multimodal diagnostic imaging helped us to better understand the modifications associated with the use of the amniotic membrane in these cases.

PURPOSE: To investigate the vascular remodeling of optical coherence tomography angiography in full-thickness macular hole surgery. METHODS: This retrospective, observational case series included 33 eyes of 33 patients with a full-thickness macular hole who underwent epiretinal membrane removal. Data were collected on best-corrected visual acuity, structural B-scan optical coherence tomography, and optical coherence tomography angiography preoperatively and at 1, 3, and 6 months postoperatively. Optical coherence tomography angiography was used to assess the retinal vascular density (VD) of the superficial vascular plexus and deep vascular plexus (DVP). Vascular density was assessed using the Early Treatment Diabetic Retinopathy Study grid for the whole, inner, and outer grids. RESULTS: A statistically significant correlation was found between the VD (whole, inner, and outer grids) of the superficial vascular plexus alone from baseline to 1-month postoperatively (P < 0.001). Similarly, VD was correlated from baseline to 1, 3, and 6 months postoperatively to the whole (P < 0.0005, F = 23.22), inner (P < 0.0005, F = 28.23), and outer Early Treatment Diabetic Retinopathy Study grids of DVP (P = 0.033, F = 3.49). The best-corrected visual acuity and VD were significantly correlated with the superficial vascular plexus and DVP at baseline and 6 months (P < 0.05, all correlations). The most significant correlation was observed at 6 months between best-corrected visual acuity and DVP in the whole, inner, and outer Early Treatment Diabetic Retinopathy Study grids (P < 0.001). CONCLUSION: Superficial vascular plexus and DVP are affected by full-thickness macular holes, with the most significant effects being on the DVP. Full-thickness macular hole surgery leads to an improvement in the best-corrected visual acuity in many eyes and the restoration of the VD, especially of the DVP.

BACKGROUND: The classification of macular hole closure patterns (MHCPs) currently relies on time domain OCT allowing only "open" and "closed" statuses or is based on inner foveal contour shape. Both classification types give no information on retinal layer reconstitution. Novel sophisticated surgical techniques lead to previously unknown MHCPs, outdating existing classifications and urging new ones. The purpose of the present study is to introduce a new classification allowing proper description of all MHCPs resulting from newer surgeries and based on the restoration of retinal layers. METHODS: Retrospective analysis of patients undergoing MH surgery with five different surgical techniques was performed. MHCPs were classified according to spectral domain optical coherence tomography (SD-OCT). Type 0: open MH (0A: flat margin, 0B: elevated, 0C: oedematous); type 1: closed MHs (1A: reconstitution all retinal layers; 1B interruption of the external layers; 1C interruption of internal layers); type 2: MH closed with autologous or heterologous filling tissue interrupting the normal foveal layered anatomy (2A: filling tissue through all layers; 2B reconstitution of normal inner retinal layers; 2C reconstitution of normal outer retinal layers; 2D H-shaped bridging of filling tissue). RESULTS: Closure rate was 95.2% (241/253). Surgical technique and vision correlated to closure pattern (p < 0.001). Type 1 MHCPs had the best post-operative visual acuity (VA) compared with type 2 and type 0 (p < 0.001). MHCPs 1A and 1C performed better than all others. MHCP at months 1 and 3 changed in 42/254 (16.5%) and remained stable in 212/254 (83.5%). Improvement in vision was higher in eyes with shifting closure pattern (0.57 ± 0.33 vs 0.51 ± 0.48 logMAR; p 0.021). CONCLUSION: MHCP classification based on retinal layer restoration properly comprises post-operative anatomic morphologies. MHCPs correlate the surgical technique and post-operative visual outcomes.

PURPOSE: To report a novel finding in patients with Fabry disease, that is, the observation by adaptive optics ophthalmoscopy of intracellular lipidic deposits in retinal vessels. METHODS: Observational two-center case series. Eighteen patients with genetically proven Fabry disease underwent flood-illumination adaptive optics ophthalmoscopy imaging (rtx1; Imagine Eyes, Orsay, France) of retinal vessels. RESULTS: Fourteen patients (78% of all patients; 7 of the 10 women and 7 of the 8 men) showed paravascular punctuate or linear opacities in both eyes. In the least-affected patients, these were seen only in the wall of precapillary arterioles as discrete spots of 5 µm to 10 µm large, whereas in those more severely affected, capillaries and first-order vessels were also involved with diffuse opacification of the wall. These deposits sometime showed a striated pattern, suggesting colocalization with vascular smooth muscle cells. CONCLUSION: Adaptive optics ophthalmoscopy of retinal vessels may be of interest for patients with Fabry disease, providing noninvasive, gradable evaluation of microvascular involvement.

BACKGROUND: To compare the efficacy of Adalimumab (ADA) in noninfectious anterior uveitis (AU) and posterior segment (PS) involvement, associated with different conditions, with a focus on Behçet's syndrome (BS). METHODS: In this retrospective, multicenter post-hoc study, we evaluated the efficacy of ADA in terms of ocular control and relapses in 96 patients with AU and PS uveitis, either idiopathic (IU) or associated with BS or with other systemic disorders (OSD) (Juvenile Idiopathic Arthritis, Psoriatic Arthritis, Ankylosing Spondylitis, Vogt-Koyanagi-Harada, Inflammatory Bowel Disease), followed in three tertiary referral centers. RESULTS: Ninety-six patients (45 AU; 51 PS uveitis) were included. Eleven had IU, 58 BS, and 27 OSD. All patients with AU achieved complete long-term ocular control. In PS uveitis, 89%, 67% and 100% of patients with BS, IU and OSD achieved ocular control at the last follow-up (> 12 months), respectively. The lowest ocular relapse rate occurred in patients with AU with BS (1/13) or IU (0/2). ADA accounted for long-term disease control, and no predictors of ocular control and relapse were identified; particularly, ocular relapses seemed not related to systemic ones. Macular edema resolved in 75% and 67% of PS uveitis with BS and IU, respectively. CONCLUSIONS: ADA controls both anterior and posterior uveitis, with an efficacy similar in IU, BS and OSD patients. In BS, the efficacy of ADA seems to be independent of demographic and clinical characteristics, and ocular relapses mostly occurred independently from systemic ones. Based on our results, ADA may represent a valid alternative in anterior refractory uveitis.

PURPOSE: To evaluate the functional and anatomical outcomes of 23-gauge or 25-gauge pars plana vitrectomy with internal limiting membrane peeling and air tamponade for the treatment of myopic foveoschisis. METHODS: Retrospective, noncomparative, interventional case series. The records of 29 patients (32 eyes), with myopic foveoschisis who were treated by 23-gauge or 25-gauge 3-port pars plana vitrectomy with internal limiting membrane peeling and air tamponade, were reviewed. At each visit, a complete ophthalmic examination, intraocular pressure, best-corrected visual acuity, and central foveal thickness measured using optical coherence tomography were assessed. RESULTS: Twenty-five eyes of 23 patients (M:F = 4:19) matched the inclusion criteria, whereas 7 eyes of 6 patients were excluded. The mean logarithm of the minimum angle of resolution best-corrected visual acuity (Snellen equivalent) was 0.62 (20/80) (SE: 0.061), and the mean preoperative central foveal thickness was 619.5 µm (SE: 16.38) at baseline. Visual acuity significantly improved of 5 Early Treatment Diabetic Retinopathy Study letters (45 letters) at the 1-month follow-up (P < 0.001), 2 lines (50 Early Treatment Diabetic Retinopathy Study letters) at the 6-month follow-up (P < 0.001), and it reached 55 Early Treatment Diabetic Retinopathy Study letters at the 1-year follow-up visit (P < 0.001). Central foveal thickness decreased to 292.4 µm (SE: 15.93), to 227.3 µm (SE: 14.05), and to 208.8 µm (SE: 12.86), respectively, at the 1-, 6-, and 12-month follow-ups (for each P < 0.001). There were no differences in best-corrected visual acuity or central foveal thickness changes between the foveal detachment group and the nonfoveal detachment group (P > 0.05). CONCLUSION: Small-gauge vitrectomy with internal limiting membrane peeling and air tamponade results in favorable anatomical and functional outcomes for patients affected by myopic macular foveoschisis.

OBJECTIVE: This study was aimed at assessing the long-term ocular control of adalimumab (ADA) in a large real-world population with noninfectious primary or secondary uveitis, focusing on the steroid-sparing effect and on disease-modifying antirheumatic drug (DMARD) cotreatment. METHODS: In this retrospective, multicenter study, the efficacy of ADA was evaluated in terms of ocular control, changes in best-corrected visual acuity (BCVA), corticosteroid-sparing effect, and drug retention rate, overall and stratified according to DMARD cotreatment. RESULTS: 106 patients were included. 88.7% had an associated systemic disease. After 6 and 12 months, proportions of patients with effective ocular control were 83.7% and 83.3%, respectively. At last the follow-up, 94.6% of patients had satisfactory ocular control. No difference in terms of ocular control at all time points emerged among patients starting ADA for ocular vs. systemic involvements. Patients with poor baseline BCVA remained stable or improved, while those with good BCVA hardly worsened. At 6 and 12 months, the median dose of prednisone significantly reduced to 5 mg/day (0-5) and 2.5 mg/day (0-5) (p < 0.001). Over a median follow-up of 36 months, 38 subjects discontinued ADA treatment. Mild to moderate side effects were reported in 7 patients (6.6%). ADA ocular control, corticosteroid-sparing effect, and drug retention rate were not influenced by the concomitant use of DMARDs. CONCLUSION: The long-term ocular control of ADA in noninfectious primary or secondary uveitis is confirmed, also for BCVA preservation. Concomitant use of DMARDs does not provide additional benefits to ADA alone in terms of ocular control, steroid spare, and drug retention rate.

BACKGROUND: The inverted flap (IF) technique has recently been introduced in macular hole (MH) surgery. The IF technique has shown an increase of the success rate in the case of large MHs and in MHs associated with high myopia. This study reports the anatomical and functional results in a large series of patients affected by MH treated using pars plana vitrectomy and gas tamponade combined with internal limiting membrane (ILM) peeling or IF. METHODS: This is a retrospective, consecutive, nonrandomized comparative study of patients affected by idiopathic or myopic MH treated using small-gauge pars plana vitrectomy (25- or 23-gauge) between January 2011 and May 2016. The patients were divided into two groups according to the ILM removal technique (complete removal vs. IF). A subgroup analysis was performed according to the MH diameter (MH < 400 µm and MH ≥ 400 µm), axial length (AL < 26 mm and AL ≥ 26 mm), and the presence of chorioretinal atrophy in the macular area (present or absent). RESULTS: We included 620 eyes of 570 patients affected by an MH, 300 patients underwent pars plana vitrectomy and ILM peeling and 320 patients underwent pars plana vitrectomy and IF. Overall, 84.94% of the patients had complete anatomical success characterized by MH closure after the operation. In particular, among the patients who underwent only ILM peeling the closure rate was 78.75%; among the patients who underwent the IF technique, it was 91.93% (P = 0.001); and among the patients affected by full-thickness MH ≥400 µm, success was achieved in 95.6% of the cases in the IF group and in 78.6% in the ILM peeling group (P = 0.001); among the patients with an axial length ≥26 mm, success was achieved in 88.4% of the cases in the IF group and in 38.9% in the ILM peeling group (P = 0.001). Average preoperative best-corrected visual acuity was 0.77 (SD = 0.32) logarithm of the minimum angle of resolution (20/118 Snellen) in the peeling group and 0.74 (SD = 0.33) logarithm of the minimum angle of resolution (20/110 Snellen) in the IF group (P = 0.31). Mean postoperative best-corrected visual acuity was 0.52 (SD = 0.42) logarithm of the minimum angle of resolution (20/66 Snellen) in the peeling group and 0.43 (SD = 0.31) logarithm of the minimum angle of resolution (20/53 Snellen) in the IF group (P = 0.003). CONCLUSION: Vitrectomy associated with the inverted ILM flap technique seems to be effective surgery for idiopathic and myopic large MHs, improving both functional and anatomical outcomes.

BACKGROUND: The evidence on the use of dexamethasone implants in the treatment of Behçet's disease (BD)-related uveitis is limited to a few cases. OBJECTIVES: To evaluate the efficacy of dexamethasone implants on ocular functional, morphological, and clinical parameters in BD patients with severe refractory uveitis. METHODS: Five eyes from five BD patients were enrolled. A single intravitreal dexamethasone injection was applied to each eye. Best corrected visual acuity (BCVA), central macular thickness (CMT) assessed with optical coherence tomography, retinal vasculitis assessed by fluorescein angiography, vitreous haze score (Nussenblatt scale), intraocular pressure (IOP), and lens status (LOCS III, Lens Opacities Classification System III) were recorded at baseline and at 1, 3, and 6 month follow-up visits. RESULTS: At baseline, all eyes showed marked macular edema and 4/5 had concomitant active retinal vasculitis. Mean BCVA was increased from baseline at each control visit with a mean improvement of 0.26 ± 0.18 lines at 6 months follow-up. Mean CMT decreased from baseline at each control visit with a mean improvement at 6 months follow-up of 198.80 ± 80.08 µm. At the end of the study, none of the eyes showed macular edema and the mean CMT was 276.80 ± 24.94 µm. Retinal vasculitis resolved in all eyes. One eye experienced an IOP spike during treatment that resolved spontaneously, and one eye developed a clinically significant lens opacity at 6 months follow-up. CONCLUSIONS: Treatment with a dexamethasone implant in BD-uveitis and inflammatory macular edema was safe and effective as an additional treatment combined with systemic immunomodulatory drugs.

BACKGROUND: Drusen are amorphous yellowish deposits beneath the sensory retina. People with drusen, particularly large drusen, are at higher risk of developing age-related macular degeneration (AMD). The most common complication in AMD is choroidal neovascularisation (CNV), the growth of new blood vessels in the centre of the macula. The risk of CNV is higher among people who are already affected by CNV in one eye.It has been observed clinically that laser photocoagulation of drusen leads to their disappearance and may prevent the occurrence of advanced disease (CNV or geographic atrophy) associated with visual loss. OBJECTIVES: To examine the effectiveness and adverse effects of laser photocoagulation of drusen in AMD. SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2015, Issue 7), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to August 2015), EMBASE (January 1980 to August 2015), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to August 2015), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 3 August 2015. SELECTION CRITERIA: Randomised controlled trials (RCTs) of laser treatment of drusen in AMD in which laser treatment had been compared with no intervention or sham treatment. Two types of trials were included. Some trials studied one eye of each participant (unilateral studies); other studies recruited participants with bilateral drusen and randomised one eye to photocoagulation or control and the fellow eye to the other group. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies and extracted data. We pooled data from unilateral and bilateral studies using a random-effects model. For the bilateral studies, we estimated the within-person correlation coefficient from one study and assumed it was valid for the others. MAIN RESULTS: The update of this review found two additional studies, totaling 11 studies that randomised 2159 participants (3580 eyes) and followed them up to two years, of which six studies (1454 participants) included people with one eye randomised to treatment and one to control. Studies were conducted in Australia, Europe and North America.Overall, the risk of bias in the included studies was low, particularly for the larger studies and for the primary outcome development of CNV. Photocoagulation did not reduce the development of CNV at two years' follow-up (odds ratio (OR) 1.07, 95% confidence interval (CI) 0.79 to 1.46, 11 studies, 2159 participants (3580 eyes), high quality evidence). This estimate means that, given an overall occurrence of CNV of 8.3% in the control group, we estimated an absolute risk reduction by no more than 1.4% in the laser group, according to the lower CI limit. Only two studies investigated the effect on the development of geographic atrophy and could not show a difference, but estimates were imprecise (OR 1.30, 95% CI 0.38 to 4.51, two studies, 148 participants (148 eyes), low quality evidence).Among secondary outcomes, photocoagulation led to drusen reduction (OR 9.16, 95% CI 6.28 to 13.4, three studies, 570 participants (944 eyes), high quality evidence) but was not shown to limit loss of 3 or more lines of visual acuity (OR 0.99, 95% CI 0.81 to 1.22, nine studies, 2002 participants (2386 eyes), moderate quality evidence).In a subgroup analysis, no difference could be shown for conventional visible (eight studies) versus subthreshold invisible (four studies) photocoagulation for the primary outcomes (P value = 0.29). The effect in the subthreshold group did not suggest a relevant benefit (OR 1.27, 95% CI 0.82 to 1.98). No study used micropulse subthreshold photocoagulation.No other adverse effects (apart from development of CNV, geographic atrophy or visual loss) were reported. AUTHORS' CONCLUSIONS: The trials included in this review confirm the clinical observation that laser photocoagulation of drusen leads to their disappearance. However, treatment does not result in a reduction in the risk of developing CNV, and was not shown to limit the occurrence of geographic atrophy or visual acuity loss.Ongoing studies are being conducted to assess whether the use of extremely short laser pulses (i.e. nanosecond laser treatment) cannot only lead to drusen regression but also prevent neovascular AMD.

PURPOSE: To evaluate the efficacy of intravitreal ranibizumab with a "pro re nata" regimen in the treatment of nonsubfoveal neovascular membranes secondary to age-related macular degeneration. METHODS: Retrospective noncomparative case series. Thirty-one eyes with naive nonsubfoveal neovascularization secondary to age-related macular degeneration were consecutively enrolled and treated with ranibizumab intravitreal injections according to a pro re nata regimen. The follow-up was performed monthly up to 6 months and quarterly up to 2 years (25 patients). Early treatment diabetic retinopathy study best-corrected visual acuity and lesion size analysis with fluorescein angiography were recorded. RESULTS: The mean baseline early treatment diabetic retinopathy study best-corrected visual acuity worsened from 20/40 (0.28 logMAR) at baseline to 20/50 (0.42 logMAR) at 1-year follow-up and 20/60 (0.53 logMAR) at 2-year follow-up. The mean lesions size nearly doubled from baseline at the 2-year follow up (1.19-2.47 mm). Twenty-two patients had one or more recurrences at 1-year follow-up. All 25 patients developed a recurrence at 2 years with 7 cases developing a recurrence by 12 months. Twelve cases progressed to subfoveal lesions by the 24-month visit. CONCLUSION: Other regimens described in the literature might result in a more the satisfactory outcome using more frequent follow-up and more frequent intravitreal injections.

Background: To investigate anatomical and functional changes of the macula caused by epiretinal membrane (ERM) peeling procedures in patients with or without posterior vitreous detachment (PVD). Methods: This is a multicentric prospective observational study on thirty-seven (37) patients affected by symptomatic ERM who underwent 25-gauge pars plana vitrectomy (PPV), induction of a PVD (as needed) and peeling of both the internal limiting membrane (ILM) and ERM. Optical coherence tomography-angiography (OCT-A) (RS 3000, Nidek, Japan) and microperimetry (MP-3, Nidek, Japan) were performed; central retinal thickness (CRT), foveal avascular zone (FAZ) area and perimeter, vessel density and perfusion density, retinal sensitivity and fixation stability (as a total mean retinal sensitivity (MRS), and MRS in the ellipse area and bivariate contour ellipse area (BCEA)) were recorded at baseline and up to postoperative month 3. Results: Eyes were classified as having complete PVD (51.4%) or incomplete PVD (48.6%). At baseline, patients with incomplete PVD had worse best-corrected distance visual acuity (BCDVA), total MRS, MRS in the ellipse area and BCEA, and higher CRT than patients with complete PVD. At month 3, the differences in BCDVA between the two groups remained statistically significant, with patients with incomplete PVD having worse results (difference: 0.199 logMAR, p < 0.001). The difference in the MRS in the ellipse area was statistically significant at month 3 (-3.378 Db, p = 0.035), with greater improvement in patients with complete PVD. Conclusions: Our study shows that patients with incomplete PVD have worse conditions at baseline than patients with complete PVD, and the differences in visual acuity and retinal sensitivity were maintained postoperatively.
RESUMO
Purpose: We evaluated the clinical features and retinal and disk perfusion characteristics by using optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) in a subset of giant cell arteritis (GCA) patients who manifested anterior ischemic optic neuropathy (AION), in a subset of GCA patients without ocular involvement, and in a control group composed of healthy controls. Methods: We performed an observational study on the eyes of GCA patients affected by arteritic AION both in acute and chronic phases, unaffected eyes of AION, eyes of GCA patients without ocular involvement, and in a control group of healthy eyes of healthy individuals. All patients underwent a complete ophthalmic examination and an OCT and OCTA of the macula and the disk. Results: The study evaluated 10 eyes of GCA patients with AION (AION group), 8 unaffected eyes of GCA patients with AION in another eye (unaffected eyes of AION group), 16 eyes of GCA patients without ocular involvement (non-ocular group), and 22 eyes of healthy patients (healthy group). The ganglion cell complex (GCC) superior and inferior thicknesses were significantly lower in the AION group compared to the unaffected eyes of the AION group (p = 0.045 and p = 0.034, respectively). All OCTA vascular density parameters of the optic disk analyzed in this study (optic nerve head (ONH) whole, superior, inferior, radial peripapillary capillary plexus (RPCP) whole, superior, inferior, lamina cribrosa (LC) whole, superior, inferior) resulted significantly lower in the AION group compared to the unaffected eyes group (p < 0.05 for all the comparisons). The ONH whole and inferior were statistically higher in the healthy group in comparison to the group of GCA patients without ocular involvement (p = 0.008 and p = 0.006, respectively). The ONH inferior was also statistically higher in the unaffected eyes of the AION group in comparison to the non-ocular group (p = 0.045). Regarding the OCTA macular vessel density parameters, the superficial capillary plexus (SCP), whole and inner, were statistically lower in the AION group compared with the unaffected eyes of the AION group. Conclusion: We found a profound vascular impairment in eyes affected by AION and areas of hypoperfusion in the eyes of patients with GCA without ocular involvement, good BCVA, and no clinically significant features. We hypothesized that these areas of lower vessel density might represent areas of subclinical hypoperfusion that cannot be detected ophthalmoscopically.
