This study aimed to find out whether three Texas state policies restricting opioid prescriptions have influenced the prescribing patterns of the oculoplastic department at the University of Texas Medical Branch (UTMB). This is a retrospective chart review of 520 patients at UTMB between 2019 and 2021, reporting the amount of morphine milliequivalents (MMEs) prescribed to patients undergoing one of eight oculoplastic procedures before and after passage of each state policy. Of 520 patients, 218 received opioids. There were no changes in MMEs/month after the first policy (95% CI: −0.1531–0.1256, p = 0.85), second policy (95% CI: −0.000997–0.00093, p = 0.97), or third policy (95% CI: −0.001431–0.00164, p = 0.096). The passage and implementation of three Texas state antiopioid policies were not associated with significant changes in opioid prescribing patterns following oculoplastic and orbital surgeries at UTMB. Average MMEs/month were driven by orbital-floor fractures, which composed most procedures overall. Limitations included the small population and that only a single provider was reviewed. Future studies would be beneficial in further evaluating the role of state legislation on opioid prescribing patterns and usage among patients.

On the cornea, daily epithelial resurfacing is a critical process to prevent the loss of normal function, ocular morbidity, corneal structure, and vision loss. There are several components to wound healing, including cellular attachment, migration, and growth. To develop a treatment for corneal epithelial healing, we studied the effect of substance P (SP) on corneal epithelial cell migration using a cell culture system of either transformed human corneal epithelial cells (SV-40), or rabbit corneal epithelial cells (SIRC). We investigated the effect of SP with insulin and insulin-like growth factor-I (IGF-1). We found that SP is synergistic with insulin and IGF-1 on the stimulation of transformed human corneal epithelial migration in a cell culture system, as well as in rabbit SIRC cells. The addition of either SP, insulin, or IGF-1 alone did not greatly affect epithelial migration, while the combination of SP and insulin or SP and IGF-1 markedly stimulated epithelial migration in a dose-dependent manner. The synergistic effects of SP with insulin and SP with IGF-1 were inhibited by the addition of the SP-specific inhibitor (CP96345). However, the effect of insulin and IGF-1 alone were not inhibited by the NK-1-specific inhibitor (CP96345). Our results are consistent with the need for the involvement of the neuropeptide SP in corneal epithelial wound healing of diabetic corneas where nerve-ending dropout occurs. Additionally, almost identical results were obtained with human and rabbit corneal epithelial cells. These results suggest that the maintenance of the normal integrity of the corneal epithelium might be regulated by both humoral and neural factors.

The management of cataracts in keratoconus patients poses a challenge due to the irregular corneal shape and variability in corneal topography, which may lead to errors in determining corneal power. In this report, we present a case of a 48-year-old male with a history of keratoconus and prior Visian Implantable Collamer lenses and Corneal Allogenic Intrastromal Ring Segments procedures, who presented with a nuclear cataract in his right eye. To address this patient’s complex case, he underwent ICL explantation, cataract extraction, and intraocular lens (IOL) implantation, utilizing the Johnson & Johnson Sensar AR40 monofocal 3-piece lens with a power of −9.5. The Barrett True K formula predicted a spherical equivalent of −1.76, and at the post-operative one-month follow-up, the uncorrected distance visual acuity (UDVA) was 20/60, with pinhole improvement to 20/50. The manifest refraction was −2.50–3.25 × 145, and the best corrected visual acuity was 20/25. This case report highlights the unique challenges encountered in managing keratoconus patients with a history of prior ICL and CAIRS procedures, followed by cataract extraction. Our findings underscore the importance of a comprehensive approach in the management of progressive keratoconus and cataracts to ensure optimal outcomes.

Neuromyelitis optica spectrum disorder (NMOSD), a demyelinating CNS disorder in which inflammatory cells infiltrate the spinal cord and optic nerve, has been identified as an AQP4-IgG-positive disease. Some of its most common clinical characteristics are optic neuritis, acute myelitis, area postrema syndrome, and brainstem syndrome. However, the relationship between aquaporin-4 (AQP4) and NMOSD appears to be involved in pathologies outside of the CNS due to the fact that autoimmune, muscular, and paraneoplastic syndromes are more common in patients with NMOSD. This perspective presents an analysis of the current literature on neuromyelitis optica in an effort to further understand and compile pathologies that arise outside of the CNS secondary to NMOSD. Recontextualizing neuromyelitis optica as a systemic condition will facilitate greater diagnostic ability and improved treatment approaches.

An in vitro study was conducted using a model of reconstituted human corneal epithelial (SkinEthic™ HCE/Human Corneal Epithelium) to test the modulation of cytokines secretion activity of Pomanox® (PMX), a standardized commercial extract of pomegranate fruit characterized by high punicalagin α + β content. Cell viability and inhibition of the release of interleukin-8 (IL-8) was evaluated in four conditions: negative control, positive inflammatory control with lipopolysaccharide (LPS) from Escherichia coli, positive anti-inflammatory control (LPS plus dexamethasone), and LPS plus PMX after 24 h of culture. The mean (±standard error of mean (SEM)) IL-8 level was 48.7 ± 5.1 pg/mL in the PMX condition vs. 172.7 ± 19.3 and 26.6 ± 1.2 in the LPS from E. coli and negative control, respectively (p < 0.05) and 93.8 ± 8.7 pg/mL in LPS plus dexamethasone (p = 0.165). The percentages of inhibition of IL-8 release were 45.7% for LPS plus dexamethasone and 63.8% for LPS plus PMX. The percentage of cell viability (86%) was also higher for the LPS plus PMX condition. The present findings add evidence to the anti-inflammatory effect of a PMX in an in vitro model of reconstituted corneal epithelial cells.

In 1931, Von Euler and Gaddum isolated substance P (SP), an undecapeptide from the tachykinin family, from equine brain and intestine tissue extracts. Numerous types of cells, including neurons, astrocytes, microglia, epithelial, and endothelial cells, as well as immune cells including T-cells, dendritic cells, and eosinophils, are responsible for its production. The corneal epithelium, immune cells, keratocytes, and neurons all express the two isoforms of NK1R, which has the highest affinity for SP. The most recent research supports SP’s contribution to corneal healing by encouraging epithelial cell migration and proliferation. Additionally, when applied to the eyes, SP has proinflammatory effects that result in miosis, intraocular inflammation, and conjunctival hyperemia. In this review article, we examine the role of substance P within the eye. We focus on the role of SP with regards to maintenance and healing of the corneal epithelium.

Background: Traumatic brain injury (TBI) can cause visual dysfunction affecting binocularity, spatial orientation, posture, and balance. Currently, there are several options for treating manifested visual disturbances; vision therapy is one of the possible treatment options. Methods: A 14-year-old female fainted and sustained trauma to the upper-temporal part of her right eyebrow. The patient presented with eye pain, a decreased visual field, and blurred vision and she exhibited great difficulties when reading. Both neurological tests and exploration of the anterior and posterior ocular segments showed results within normal limits. The patient was diagnosed with fusional vergence dysfunction, associated with accommodative infacility and oculomotor dysfunction. To eliminate her symptoms, a visual rehabilitation program was implemented; it consisted of accommodative, anti-suppressive, vergential, motility, hand–eye coordination, and peripheral vision exercises. Results: The symptoms manifested by the patient gradually dissipated throughout the course of therapy. However, not all optometric parameters reached normal values after visual therapy, which could indicate a traumatic injury that limited the achievement of normal optometric ranges. Conclusions: After a mild traumatic brain injury (mTBI), it is necessary to carry out a complete examination of the patient’s visual function. This visual examination must include an analysis of vergences, ocular motility, and the accommodative system to obtain an accurate diagnosis. The outcomes of the present clinical case imply that visual therapy should be considered as a treatment in cases of mTBIs.

(1) Background: After filtering surgery, bleb morphology is an indicator of the factors that may determine the final intraocular pressure (IOP). The present study aimed to evaluate and compare filtering bleb characteristics after combined cataract and glaucoma surgery. (2) Methods: We conducted a prospective multi-center randomized trial. Eyes with glaucoma and cataract were randomly assigned to either phacoemulsification and filtration surgery with an EX-PRESS implant (Alcon) or non-penetrating deep sclerectomy (NPDS) with an ESNOPER implant (AJL). The bleb characteristics were assessed with the Moorfields bleb grading system at months 1 and 12 of follow-up, and the relationship with IOP was analyzed. (3) Results: There were significant changes in bleb appearance between the assessments at month 1 and month 12. The changes in bleb appearance were more evident in the EX-PRESS group. The central area in the EX-PRESS group decreased from 2.9 at month 1 to 2.4 at month 12 (p = 0.014). Bleb height in the EX-PRESS group decreased from 2.3 at month 1 to 1.8 at month 12 (p = 0.034). The vascularity of the central area in the NPDS group decreased from 1.8 at month 1 to 1.3 at month 12 (p = 0.02). The maximal bleb area was inversely related (r = −0.39; p = 0.03) to the IOP in the NPDS group at month 1. Vascularity in the central area was directly related (r = 0.39; p = 0.01) to a higher IOP in the EX-PRESS group at month 1. Vascularity in the central area (r = 0.56; p < 0.001) and maximal area (r = 0.37; p = 0.012) at month 1 was directly related to a higher IOP in the EX-PRESS group at month 12. (4) Conclusions: More intense vascularity at month 1 was related to a higher final IOP in the EX-PRESS group. Larger blebs were associated with a lower IOP in the NPDS group.

Here, we present a case of floppy iris leading to positional pupillary capture by a sutureless, scleral-fixated intraocular lens (IOL) causing recurrent uveitis-glaucoma-hyphema (UGH) syndrome. The patient developed recurrent episodes of UGH syndrome after dislocated IOL removal and the placement of sutureless, scleral-fixated IOL. Gravitationally dependent pupillary capture was noted with the superior iris moving in front of and behind the IOL, depending on head positioning. Ultrasonography showed a floppy iris that moved with shifting gaze. The lack of the capsular bag may have contributed to extreme iris movements. This finding may be secondary to a combination of a lack of zonular support and capsular bag support as well as the lack of vitreous support following vitrectomy. When possible, secondary IOL placement behind a peripherally preserved capsular bag may reduce the risk of UGH.

Endophthalmitis is a serious ophthalmologic condition involving purulent inflammation of the intraocular spaces. Fungal endophthalmitis is a highly sight-threatening condition that can be complicated by difficulties in diagnosis and therapeutic delay. We report herein a rare case of bilateral endogenous Candida albicans endophthalmitis with favorable outcome. High suspicion of fungal origin is essential since the diagnosis for fungal endophthalmitis is usually based on the ophthalmological exhibition in combination with the presence of fungemia or predisposing factors. Only prompt initiation of systemic, intravitreal and surgical treatment may reduce ocular morbidity or even mortality.
