Clinical features, diagnosis, treatment, and course of ocular sarcoidosis with or without uveitis: A retrospective, comparative study.

OBJECTIVE: To evaluate and compare characteristics, diagnosis, treatment, visual prognosis, and course between ocular sarcoidosis with or without uveitis in a population in Southern France. METHODS: We retrospectively analyzed data from patients with ocular sarcoidosis in a tertiary eye care center in Nice from January 2003 to December 2021. The inclusion criterion was biopsy-proven ocular sarcoidosis according to IWOS criteria as the first clinical manifestation of sarcoidosis. RESULTS: A total of 25 patients were included. Twenty patients had uveitis (70% panuveitis, 20% intermediate uveitis, and 10% anterior uveitis) and five patients had non-uveitic ocular sarcoidosis (one patient with dacryoadenitis, one patient with orbital granuloma, two patients with palpebral granuloma, and one patient with episcleritis). Only the cases with uveitis had bilateral involvement (85% of cases). There was no significant difference in ethnicity, biopsy diagnosis, systemic manifestations, or treatment between the two groups. Final visual outcomes remained good for both groups, with 96% of patients with BCVA>20/50, with no significant difference. Patients with non-uveitic sarcoidosis experienced less recurrence on treatment (P=0.042) and more remission (P=0.038) than patients with uveitis. Eighty percent of patients with uveitis had at least three suggestive clinical intraocular signs meeting IWOS criteria. CONCLUSION: In this population in Southern France, uveitis was the most common presentation of ocular sarcoidosis. The type of ocular sarcoidosis does not appear to be correlated with the type of systemic manifestations, use of systemic therapy, or visual prognosis, but patients with non-uveitic ocular sarcoidosis appear to have a better course with fewer recurrences on treatment and more remission than patients with uveitic ocular sarcoidosis.

Intraoperative iStent versus postoperative selective laser trabeculoplasty in early glaucoma patients undergoing cataract surgery: A retrospective comparative study.

PURPOSE: To compare the efficacy and safety of iStent inject® versus 360° selective laser trabeculoplasty (SLT) in patients with early glaucoma undergoing cataract surgery. METHODS: A retrospective non-randomized study was conducted in 73 eyes divided into two groups: cataract surgery+intraoperative iStent (n=40) versus cataract surgery+postoperative SLT at one month (n=33). The primary endpoint was intraocular pressure (IOP) lowering≥20% between baseline and 6 months postoperatively. The secondary endpoints were IOP lowering at 1, 6 and 12 months, and the mean number of IOP-lowering medications at 6 and 12 months. RESULTS: The mean baseline IOP was 19.1 mmHg with no significant difference between groups. The mean baseline number of IOP-lowering medications was higher in the iStent group (n=1.95) compared to the SLT group (n=1.53; P=0.04). At 6 months, 18 (60%) patients in the SLT group and 20 (51%) patients in the iStent group achieved IOP lowering≥20% with no significant difference between groups (P=0.431). At 6 months, no difference in the mean number of IOP-lowering medications was found between groups (-0.92 and -0.89 in the iStent and SLT groups, respectively). Similar results were found at 12 months. CONCLUSION: These results suggest similar safety and efficacy of intraoperative iStent and postoperative 360° SLT in lowering IOP and reducing glaucoma eye drops in early glaucoma patients undergoing cataract surgery. Treatment choice should be based on the ophthalmologist's experience and on the cost-benefit ratio.

Optic nerve sheath fenestration: Current status in France and comparison of 6 different surgical approaches.

PURPOSE: Optic nerve sheath fenestration (ONSF) is a surgical procedure commonly performed in the Anglo-Saxon countries for the treatment of medically refractory idiopathic intracranial hypertension (IIH). We chose to compare 6 different trans-orbital surgical approaches to ONSF. We also desired to determine the number of optic nerve decompression procedures performed in France in 2019 and 2020. METHODS: Four fresh frozen orbits were dissected at the University of Nice anatomy laboratory. We performed the following surgical approaches: (i) eyelid crease, (ii) lid-split, (iii) medial transconjunctival with medial rectus disinsertion, (iv) medial transconjunctival without rectus disinsertion, (v) lateral transconjunctival and (vi) lateral orbitotomy. For each surgical approach, we measured the distance between the incision and the optic nerve dura mater. We also extracted data from the French National PMSI (Programme de Médicalisation des Systèmes d' Information) database from January 2019 through December 2020 to determine the annual number of optic nerve decompression procedures. RESULTS: The lid crease and medial transconjunctival approaches provided the shortest distance to the optic nerve (average 21mm and 24mm, respectively) and the lowest levels of difficulty compared to the other surgical routes. A total of 23 and 45 optic nerve decompressions were performed in France in 2019 and 2020, respectively. Among them, only 2 and 7 procedures, respectively, were performed through a trans-orbital approach. CONCLUSION: Upper lid crease incision and medial transconjunctival approaches are the most direct and easiest surgical routes when performing an ONSF. We found that ONSF was rarely performed in France. We strongly recommend close cooperation between ophthalmologists, neurologists, neurosurgeons and interventional radiologists.

Incidence of Orbital Exenteration: A Nationwide Study in France over the 2006-2017 Period.

PURPOSE: Orbital exenteration is a radical and disfiguring surgery mainly performed for treating orbital malignancies. Recently, several studies found favorable results in terms of overall survival with eye-sparing surgeries combined with targeted therapies and/or radiotherapy. The aim of this study was to assess the incidence of orbital exenteration and its evolution in France between 2006 and 2017. METHODS: A national observational cohort study was conducted in France between January 2006 and December 2017. Data were collected from the national PMSI (Programme de Médicalisation des Systèmes d'Information) database provided by the CNAM (Caisse Nationale de l'Assurance Maladie). All patients undergoing orbital exenteration over the study period in France were included. RESULTS: One thousand and fifty-seven patients were included. The mean annual number of orbital exenterations was 88.1 (63-117), corresponding to a mean incidence of 0.1/100,000 inhabitants/year. A male predominance was noted (n = 626, 59.2%). Exenteration was mainly performed between 75 and 79 years. The underlying etiology was available for 821 patients (77.7%): malignancies were the most common (n = 755; 92.0%) followed by infectious diseases (n = 16; 1.9%). Over the study period, no statistical difference in the mean incidence of orbital exenteration was found (p = .132). CONCLUSION: The mean annual incidence of orbital exenteration was 0.1/100,000 inhabitants in France and was not significantly modified during the study period.

Feelings, preoperative anxiety, and need for information in patients undergoing intravitreal injections.

PURPOSE: To assess feelings, preoperative anxiety, and need for information in patients undergoing intravitreal injections (IVI). METHODS: An observational cross-sectional study was conducted in our tertiary university care center between December 2017 and December 2018. Consecutive patients undergoing IVI were included. A paper survey was completed before and after IVI to assess patient experience. Preoperative anxiety and need for information were assessed using the Amsterdam Preoperative Anxiety Information Scale (APAIS) score. RESULTS: Hundred patients with a median age of 76.5 years (42-95, SD = 10.1) were included. Median best-corrected visual acuity (BCVA) in both eyes was 0.4 logMAR. Main IVI indications were wet age-related macular degeneration (n = 58), diabetic macular edema (n = 19), and venous occlusion (n = 16). The IVI most unpleasant steps were as follows: using an eyelid retractor, needle entry, changing of physician from one IVI to another, the pre-IVI waiting time, and the high number of IVI required for disease control. Preoperative anxiety (APAIS score ≥ 11) was correlated in the multivariate analysis with the need for information (p = 0.004), changing of ophthalmologist between different IVI sessions (p = 0.006), and pain expected before the IVI (p = 0.010). The need for information (APAIS score ≥ 5) was only associated with the preoperative anxiety in the multivariate analysis (p = 0.001). CONCLUSION: Preoperative anxiety and need for information are common in patients undergoing IVI even after many IVI. Being injected by different practitioners was strongly correlated with preoperative anxiety and should be avoided as much as possible. Better educational and information programs are needed.

[Anatomical description of the retro-caruncular approach and its application in oculoplastics: A cadaveric study]. / Bases anatomiques de la voie rétro-caronculaire et ses applications cliniques en oculoplastique : étude sur cadavre.

PURPOSE: To describe the anatomical landmarks of the retro-caruncular approach and its clinical applications based on a cadaveric study. PATIENTS AND METHOD: A dissection of 8 orbits providing from 4 fresh cadavers was carried out at the anatomical laboratory of the University Hospital of Nice, France between October 2018 and January 2019. RESULTS: Main anatomical relationships encountered are anteriorly the Duverney-Horner muscle and the lacrimal sac, posteriorly the anterior and posterior ethmoidal arteries, superiorly the pulley of the superior oblique muscle, inferiorly the lacrimonasal duct and the tendon of the inferior oblique muscle. The retro-caruncular approach allows a safe surgical access behind the lacrimal sac and Duverney-Horner muscle. Many oculoplastic surgical procedures can be performed through this approach: dacryocystorhinostomy, medial orbital fractures repair, "médial" orbital "décompression", biopsy of medial and extraconal tumours, medial periosteal fixation in third-nerve palsy. CONCLUSION: The retro-caruncular approach is a safe procedure avoiding skin incision. It allows a wide surgical space even if it is reduced compared to a more conventional skin route. It requires a great anatomical knowledge and a longer surgical learning curve.

[Local, regional and systemic dissemination of choroidal melanoma : Clinical and pathological correlation from 2 cases]. / Dissémination locorégionale et systémique du mélanome choroïdien : corrélation anatomoclinique à partir de 2 cas.

PURPOSE: To describe didactically the local, regional and systemic spread of choroidal melanoma. PATIENTS AND METHODS: Two patients who had undergone primary enucleation for the management of choroidal melanoma in 2018 at the University Hospital of Nice were included. Extrascleral extension and invasion of the vortex veins were evaluated, as well as synchronous and metachronous metastases, based on our database. RESULTS: Patient 1 was diagnosed with large choroidal melanoma with partial scleral invasion and vortex vein involvement. Cytogenetic analysis demonstrated a loss of chromosome 3, and a gain of chromosome 8q. Systemic work-up was unremarkable. Patient 2 was diagnosed with a large choroidal melanoma with extrascleral extension and vortex vein involvement. Cytogenetic analysis demonstrated a loss of chromosome 3 and a gain of chromosome 8q. Systemic work-up revealed several liver metastases. A total of 1762 patients were included in our database. Eighty-five patients (4.8 %) and 46 patients (2.6 %) experienced vortex vein invasion and extrascleral extension respectively. Patients with vortex vein invasion were diagnosed with synchronous and metachronous liver metastases in 1.2 % and 18.8 % respectively. Patients with extrascleral extension had synchronous and metachronous liver metastases in 6.5 % and 30.4 % respectively. The mean follow-up was 49.4 months (1-180). CONCLUSION: Extrascleral extension and vortex vein invasion illustrate the local, regional and systemic spread of choroidal melanoma. The latter are often associated with genetically aggressive tumours associated with high metastatic risk.
