Vision Loss Secondary to Facial and Periorbital Steroid Injection: A Systematic Review

Peri-levator Betamethasone Versus Triamcinolone Injection in Management of Thyroid Eye Disease-related Upper Eyelid Retraction Without Proptosis

PURPOSE

To compare the efficacy of peri-levator injection of both betamethasone and triamcinolone in the management of thyroid eye disease-related upper eyelid retraction without proptosis.

METHODS

This prospective, double-blind, randomized clinical trial was conducted at Assiut University Hospital, Upper Egypt in the period between December 2021 and October 2023. The study included 47 patients (56 eyes) and was divided into 2 groups. In group A, 1 ml betamethasone was injected into the peri-levator area, while in group B, 1 ml triamcinolone was injected. The injection was repeated every month for up to 5 injections if there was an improvement in margin reflex distance 1 (MRD1). The injection was stopped if MRD1 reached the normal value or if 2 successive injections caused no improvement in MRD1. The postinjection outcome was divided into: 1) effective if MRD1 reached the normal ≤4.5 mm; 2) partially effective if MRD1 was improved but did not reach the normal; and 3) ineffective if there was no improvement in MRD1. The follow up ranged from 6 to 20 months.

RESULTS

In group A, the injection was effective in 26 eyes (92.9%) and partially effective in 2 eyes (7.1%). In group B, the injection was effective in 17 eyes (60.7%), partially effective in 6 eyes (21.4%), and ineffective in 5 eyes (17.9%). The mean number of injections was significantly lower in group A than in group B: 1.61 ± 0.50 versus 2.36 ± 1.16.

CONCLUSIONS

This study results suggest that betamethasone is more effective with a smaller number of injections than triamcinolone in the management of thyroid eye disease-related upper eyelid retraction.

Orbital corticosteroid injections for the treatment of active thyroid eye disease

Purpose

To study the efficacy of orbital injections of triamcinolone acetonide mixed 1:1 with dexamethasone in the treatment of active thyroid eye disease.

Methods

Patients that received orbital injection(s) of triamcinolone acetonide mixed 1:1 with dexamethasone for thyroid eye disease were included in this retrospective study. Demographic and clinical data were collected from the pre-treatment and 1 month follow up evaluations. Clinical data included subjective pain and diplopia scores, best-corrected visual acuity, Intraocular pressure, extraocular motility, clinical activity score, Hertel exophthalmometry, and upper eyelid margin to reflex distance.

Results

Fifteen patients, 33 orbital injections, were included in the study. The average patient age was 59.2 years (SD ± 13.0) and 89% female. Subjectively, 67% of patients reported improvement of orbital pain and pressure versus 28% stable and 5% worse (p <0.001). Post-procedure clinical activity score decreased from 3.84 to 3.00 (p = 0.0004). There were no significant differences in upper eyelid margin to reflex distance (4.1 ± 1.4 mm vs. 4.3 ± 2.6 mm, p = 0.45), Hertel exophthalmometry (21.7 ± 9.4 mm vs. 21.8 ± 7.6 mm, p = 0.56), or extraocular motility (21% improved vs. 72% stable and 7% worsening, p = 0.50). No steroid-responsive increases in intraocular pressure or injection-related complications were reported.

Conclusion

Orbital steroid injections can successfully reduce symptoms of TED and may be a reliable tool in the treatment of TED as a relatively safe, fast-acting, efficacious treatment option, particularly as a bridge to other therapies.

The Lowly Chalazion

Chalazia are localized cysts of chronic lipogranulomatous inflammation arising from the obstruction of sebaceous glands of the eyelid tarsal plate, including the Meibomian gland (deep chalazion) or Zeis gland (superficial chalazion). This disease entity is differentiated from the hordeolum (stye), an acute purulent localized swelling of the eyelid often associated with an eyelash follicle, Zeis gland, or Moll gland obstruction and infection. Ambiguously, the chalazion, hordeolum, and blepharitis are commonly categorized and described on a continuum in the literature. While it is one of the most common eyelid disorders across all age demographics, the chalazion remains largely understudied and pathophysiological, epidemiological, and therapeutic findings exist fragmented in the literature. We discuss current understandings of the chalazion and provide current best practice guidelines supported by clinical anecdotal evidence.
