Anophthalmic socket syndrome determines functional deficits and facial deformities, and may lead to poor psychological outcomes. This review aims to comprehensively evaluate the features of the syndrome, based on literature review and authors’ clinical and surgical experience. An electronic database (PubMed,MEDLINE and Google Scholar) search of all articles written in English and non-English language with abstract translated to English on anophthalmic socket syndrome was performed. Data reviewed included demographics, presentations, investigations, management, complications and outcomes. Different types of orbital implants were evaluated; the management of implant exposure was examined; different orbital volume enhancement procedures such as secondary implantation, subperiosteal implants and the use of fillers in anophthalmic patients were described; the problems related to socket contraction were outlined; the treatment options for chronic anophthalmic socket pain and phantom eye syndrome were assessed; the most recent advances in the management of congenital anophthalmia were described. Current clinical evidence does not support a specific orbital implant; late exposure of porous implants may be due to pegging, which currently is seldom used; filler absorption in the orbit appears to be faster than in the dermis, and repeated treatments could be a potential source of inflammation; socket contraction results in significant functional and psychological disability, and management is challenging. Patients affected by anophthalmic socket pain and phantom eye syndrome need specific counseling. It is auspicable to use a standardized protocol to treat children affected by clinical congenital anophthalmia; dermis fat graft is a suitable option in these patients as it helps continued socket expansion. Dermis fat graft can also address the volume deficit in case of explantation of exposed implants and in contracted sockets in both children and adults. Appropriate clinical care is essential, as adequate prosthesis wearing improves the quality of life of anophthalmic patients.

The authors analyzed the cosmetic and functional results of a series of patients with unilateral congenital ptosis who underwent levator resection, to compare the outcome of surgery according to the age of intervention, and to evaluate the chance of ptosis recurrence in different age groups. Analysis of the clinical charts of 44 patients who underwent a unilateral levator muscle resection under the care of one surgeon from February 2000 to March 2012 was performed. Age at the time of surgery ranged from 2.1 to 12 years. The study population was divided into different groups according to the age of surgery. Preoperative evaluation included measurements of upper eyelid margin reflex distance (MRD1), levator function, frontalis function, and complete extraocular motility examination. This study adheres to the principles outlined in the Declaration of Helsinki. The patients’ follow-up ranged between 2 and 12 years. The outcome of surgery was more satisfactory (MRD1 increase: p < 0.002) and the increase of levator function was better (p < 0.0001) when surgery was performed in children aged 2 to 4 years. No ptosis recurrence was observed in children aged 2 to 4 years, as opposed to 6 (22%) children of other groups (p = 0.067). Unilateral levator resection effectively reduces the asymmetry between eyelids. The age of the operation appears to influence the outcome of surgery, as in this series cosmetic and functional results are better and the rate of ptosis recurrence is lower if the child is operated on before the age of 4 years.

Background: Thyroid eye disease (TED) is a rare autoimmune orbital disorder predominantly associated with Graves’ disease. It is characterized by orbital inflammation, tissue remodeling, and potential visual morbidity. Conventional therapies, particularly systemic glucocorticoids, offer only partial symptomatic relief, failing to reverse chronic structural changes such as proptosis and diplopia, and are associated with substantial adverse effects. This review aims to synthesize recent developments in understandings of TED pathogenesis and to critically evaluate emerging therapeutic strategies. Methods: A systematic literature review was conducted using MEDLINE, Embase, and international clinical trial registries focusing on pivotal clinical trials and investigational therapies targeting core molecular pathways involved in TED. Results: Current evidence suggests that TED pathogenesis is primarily driven by the autoimmune activation of orbital fibroblasts (OFs) through thyrotropin receptor (TSH-R) and insulin-like growth factor-1 receptor (IGF-1R) signaling. Teprotumumab, a monoclonal IGF-1R inhibitor and the first therapy approved by the U.S. Food and Drug Administration for TED, has demonstrated substantial clinical benefit, including improvements in proptosis, diplopia, and quality of life. However, concerns remain regarding relapse rates and treatment-associated adverse events, particularly hearing impairment. Investigational therapies, including next-generation IGF-1R inhibitors, small-molecule antagonists, TSH-R inhibitors, neonatal Fc receptor (FcRn) blockers, cytokine-targeting agents, and gene-based interventions, are under development. These novel approaches aim to address both inflammatory and fibrotic components of TED. Conclusions: Teprotumumab has changed TED management but sustained control and toxicity reduction remain challenges. Future therapies should focus on targeted, mechanism-based, personalized approaches to improve long-term outcomes and patient quality of life.

Purpose: To evaluate the outcome of orbital decompression, strabismus and/or eyelid surgery in patients with moderate to severe thyroid-associated orbitopathy, when combined approach is preferred. Methods: Retrospective, comparative, non-randomized review of 45 patients operated on from 2015 to 2018. Simultaneous decompression, eyelid and/or strabismus surgery was performed in 34 eyes of 20 subjects (group 1). Patients with multi-step procedures were used as control groups: group 2 included patients with staged decompression and eyelid retraction surgery (15 cases, 19 eyes); group 3 included patients with staged decompression and vertical strabismus surgery (10 cases, 13 eyes). Mean follow-up was 2.9 ± 1.8 years. Mann Whitney two-tailed test was used for paired data, and Fisher’s exact test for categorical data; p <.05 were considered statistically significant. Results: Changes in margin reflex distance were not significantly different among patients of subgroup 1A (11 patients, one-step decompression/eyelid surgery) and group 2 (p >.05). Improvement in postoperative diplopia were not significantly different among patients of subgroup 1B (9 cases, one-step decompression/strabismus/eyelid surgery) and group 3 (p >.05). One patient of group 1 had recurrent dysthyroid optic neuropathy that recovered with steroid treatment. No other complications occurred in the one-step surgery group. Conclusions: Simultaneous orbital decompression, strabismus and/or eyelid surgery resolved dysthyroid optic neuropathy, decreased proptosis, improved diplopia and eyelid position with a range comparable to that of a multi-step technique. If confirmed in prospective controlled studies, a one-stage approach might be advised to reduce the costs and time needed for rehabilitation in selected patients.
