Background: Inverted Internal Limiting Membrane (ILM)-flap technique would seem to lead to higher closure rate and better visual acuity than traditional procedure with ILM peeling for the treatment of large macular hole (LMH). Visual acuity recovery does not reveal many other functional changes related to surgical approach. Our purpose was to evaluate macular function and morphology over a 1-year follow-up after inverted ILM-flap technique for LMH by using microperimetry in order to predict visual prognosis. Methods: This study was a prospective unrandomized single-center study. 23 eyes of 22 patients with idiopathic LMH, with a minimum diameter ranging from 400 to 1000 μm, were included. All patients underwent vitrectomy with inverted ILM-flap technique and gas tamponade. We analyzed macular hole closure rate and functional outcomes including best-corrected visual acuity (BCVA), macular sensitivity (MS) at central 12° and central macular sensitivity (CMS) at central 4°, and fixation behavior as bivariate contour ellipse area (BCEA, degrees²) at 68%, 95%, and 99% of fixation points measured by microperimeter, over a follow-up of 12 months. Results: The macular hole closure rate was 98%. The BCVA improved from 20/230 (Logmar, 1.06 ± 0.34) to 20/59 (logMar, 0.47 ± 0.45) at last follow-up (p < 0.001). Retinal sensitivity and BCEA significantly improved (MS, p = 0.001; CMS, p < 0.0001; BCEA: 68%, p < 0.01; 95%, p < 0.01; 99%, p = 0.001). Multiple stepwise regression analysis showed the final BCVA was significantly associated with macular hole size (β = 0.002, p = 0.03), preoperative MS (β = − 0.06, p = 0.001) and BCEA at 95% and 99% of fixation points (β = − 0.12, p = 0.01; β = 0.06, p = 0.01). Conclusions: Inverted ILM-flap technique for LMH results in good morphologic and functional outcomes. Macular hole size and microperimetric parameters as preoperative MS and BCEA have a predictive role on post-surgical visual acuity.

Background: Despite the high closure rate of large macular hole (LMH) after surgery, visual recovery is often worse than expected. Microperimetric biofeedback can improve visual function in macular pathologies. We evaluated the efficacy of biofeedback on macular function after successful inverted flap technique for LMH. Methods: In this prospective comparative study, 26 patients after LMH surgical closure were enrolled. The whole sample was equally divided into two groups. In Group 1 (trained), patients underwent a double cycle of microperimetric biofeedback, using structured light stimulus plus acoustic tone; in Group 2 (control), patients underwent scheduled visits. We analyzed visual acuity, retinal sensitivity at central 12° (macular sensitivity, MS) and 4° (central macular sensitivity, CMS), and fixation stability over twelve months. Results: Visual acuity improved mainly in the trained group, without any significant differences between the groups (p > 0.05). Only after training did MS significantly improve (p = 0.01). CMS more significantly improved in the trained (p < 0.001) than the control group (p < 0.01) (Group 1 vs. 2, p = 0.004). Only in the trained group did fixation significantly improve (3 months, p ≤ 0.03; 12 months, p ≤ 0.01). An equality test on matched data confirmed a greater significant improvement of CMS (p ≤ 0.02) at all follow-up and fixation (p ≤ 0.02) at last follow-up after training. Conclusions: Microperimetric biofeedback consolidates and increases the improvement of retinal sensitivity and fixation gained after successful inverted flap technique.

Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disease common in children and young adults. Uveitis is the most frequent serious extra-articular JIA manifestation and can lead to severe ocular complications, vision loss, and permanent blindness. This study aims to evaluate the psychological condition and the quality of life of children affected by JIA associated with uveitis (JIA-U) and the repercussion of this condition on parents. Thirty children and adolescents with active uveitis (Uveitis group) and comorbid joint symptoms of JIA were referred to the Unit of Ophthalmology, Giovanni XXIII Hospital of Bari, and 30 age-matched healthy controls (Healthy group) were enrolled with their parents. Four questionnaires were administered: Child Behaviour Checklist (CBCL), Parent Stress Index in Short Form (PSI), Pediatric Quality of Life Inventory (PedsQL), and Coping Inventory for Stressful Situations (CISS). The data were collected from February 2021 to December 2021. No significant differences between the two groups in CBCL, PSI, or CISS tests were shown (p > 0.05). Conversely, significant differences between the two groups were observed in the PedsQL (p < 0.05). This study shows how several ocular complications, recurrent eye examinations, and the rigor of long-term treatment may negatively influence health-related quality of life in children with JIA-U.

Background/purpose: Full-thickness macular hole is a complication of idiopathic macular telangiectasia type 2 with a low surgical closure rate and a poor functional recovery. We analyze morphologic and functional outcomes after an inverted internal limiting membrane-flap technique for full-thickness macular hole complicating idiopathic macular telangiectasia type 2 using optical coherence tomography and microperimetry. Case report: A 77-year-old man presented us complaining visual impairment in the left eye (20/40) due to a full-thickness macular hole complicating idiopathic macular telangiectasia type 2. The patient underwent vitrectomy with an inverted internal limiting membrane-flap technique and injection of 22% SF6 gas. Optical coherence tomography and functional analysis, including visual acuity test and microperimetry, were performed before surgery and over 3 months. Optical coherence tomography scans revealed macular hole closure at 1-month follow-up. Visual acuity and retinal sensitivity improved from 20/40 to 20/20 and from 13.1 to 14.9 dB, respectively. Fixation stability (bivariate contour ellipse area) improved from 2.02 to 1.58 deg², from 5.44 to 4.24 deg² and from 9.72 to 7.58 deg², at 68%, 95%, and 99% of fixation points, respectively. Conclusion: Inverted internal limiting membrane-flap technique may be an alternative approach in patients with full-thickness macular hole complicating diopathic macular telangiectasia type 2, and microperimetry may be a useful tool to analyze related functional changes.

Purpose: Spectral-domain optical coherence tomography (SD-OCT) was used to evaluate, in patients with multiple sclerosis without a history of optic neuritis (MSNON), the proportion of the different macular ganglion cell-inner plexiform layer complex (mGCIP) defect patterns. The results were compared with those of healthy controls (HCs). Methods: In this cross-sectional case-control study, 34 eyes of 34 individuals, 17 with MSNON and 17 HCs, were evaluated. All participants underwent mGCIP thickness measurement using SD-OCT (Zeiss Cirrus HD-OCT 4000, macular cube protocol). The mGCIP defect patterns were classified in nine types (minimal, inner, outer, diffuse mild, diffuse severe inferior confined, inferior dominant, superior confined, and superior dominant), according to the shape derived by the deviation map of the instrument, and the proportion of each type was assessed. Results: A mGCIP defect pattern was detected in 70.5% of MSNON eyes, with an inner type as the most frequent pattern (47%), followed by the outer type (11.7%) and the inferior confined type (11.7%). No defect was found in Hcs. Conclusions: A significant thinning of the mGCIP with the frequent presence of an inner defect was seen in MSNON patients. The presence of this defect may serve as a biomarker of subclinical optic nerve involvement in MS patients.

We investigated the molecular causes of an unusual pigmented and ulcerated iris lesion detected in a patient diagnosed with neurofibromatosis type 1 (NF1). A 52-year-old man was referred to our clinic with a non-traumatic ulcer in his left eye. Hyphema reabsorption disclosed a pigmented iris mass, thus ultrasound biomicroscopy and anterior segment fluorescein angiography were performed to investigate for the presence of a malignant lesion. Upon angiography, the lesion appeared highly vascularized but prevented posterior iris examination. Therefore, a gonioscopy was executed revealing extension of the lesion into the peripheral iris. Histopathology of the excisional iris biopsy revealed iris melanoma over a dysplastic nevus. NF1 is an autosomal dominant disorder characterized by pigmented cutaneous lesions, multiple skin tumors, and spinal and cranial nerve tumors. Uveal melanoma is the most common primary intraocular malignancy in adults. Up to 92% of cutaneous melanomas occur in patients with dysplastic nevus syndrome. Skin melanomas have been found in 0.1%–5.4% of NF1 patients. In literature, only 18 reports of uveal melanoma have been documented in association with NF1, including three cases of iris melanoma. NF1 gene testing identified a causative mutation in the germline but no loss of the wild-type allele in the iris melanoma. Occurrence of both diseases in one patient is extremely rare, but the common origin of Schwann cells and melanoblasts suggests a non-casual association. Therefore, we propose that NF1 patients should be screened for nevi, both cutaneous and uveal, for better patients’ management.
