Purpose: To investigate indicators of dry eye disease that influence punctal plug loss. Methods: A retrospective review was conducted on patients who received SuperFlex® punctal plugs. To analyze the relationship between punctal plug loss and markers for dry eye, patients were categorized into a loss group, defined as those who experienced unintended loss within 3 months of insertion, and a retention group. In total, 11 indicators were compared between the two groups, including meibomian gland expressibility, cloudiness of meibomian gland secretions, telangiectasis of the eyelid margin, tear osmolarity, Schirmer’s test value, the expression levels of matrix metalloproteinase-9 in tears, NEI/Industry grading system score, Sjögren’s International Collaborative Clinical Alliance ocular staining score, tear lipid layer thickness (LLT), and meiboscore. Results: In all, 47 eyes of 30 patients were included in the study. Of these, 16 eyes (34%) were assigned to the loss group. Meibomian gland expressibility grade was significantly higher in the loss group (1.60 ± 0.58) compared to the retention group (1.04 ± 0.37, p = 0.0247). Additionally, LLT was significantly lower in the loss group (58.7 ± 17.0 nm vs. 88.4 ± 17.6 nm, p = 0.0303). However, no significant correlations were found between punctal plug loss and other indicators of dry eye. Conclusions Worse meibomian gland expressibility and thinner LLT are associated with a higher rate of punctal plug loss.

Purpose: We report a case of bilateral nasal and temporal four-site scleromalacia following cosmetic conjunctivectomy, successfully managed with simultaneous restoration surgery at all four sites using autologous tragal perichondrium and preserved scleral graft.Case summary: A 56-year-old woman who underwent cosmetic conjunctivectomy on both eyes 15 years earlier, presented with intermittent eye pain. Examination revealed scleromalacia with calcium plaques in all four nasal and temporal scleral areas. The most extensive avascular area was in the nasal region of the right eye, and the most prominent uveal exposure was in the nasal area of the left eye. Considering the lesion and exposure sizes of the avascular zone and uvea exposure, preserved sclera was transplanted to the temporal and nasal areas of the right eye, while autologous tragal perichondrium was transplanted to the nasal area of the left eye. Tenon's capsule vessels were fixed with pedicle flaps in all four surgical areas for vascularization. Frozen amniotic membrane was transplanted in the nasal area of the left eye, where the conjunctival defect was substantial, and in the lateral area of the left eye, where no graft was used. The conjunctival epithelium was closed using autologous conjunctival flaps in all four areas. Post-surgery, successful engraftment and vascularization of the graft materials were observed in both eyes. Conclusions Even with multiple areas of scleromalacia in both eyes, successful results can be achieved during simultaneous surgery if an appropriate graft material is selected and the surgery is performed utilizing principles of tissue restoration.

Purpose: We present a case of malignant glaucoma following cataract surgery in a nanophthalmic eye.Case summary: A 74-year-old woman with a nanophthalmic right eye (axial length 20.51 mm) underwent cataract surgery at a local hospital. One week postoperatively, she presented with a dislocated intraocular lens (IOL) and a shallow anterior chamber. Malignant glaucoma was suspected, and the patient underwent pars plana vitrectomy followed by neodymium-doped yttrium aluminum garnet laser posterior capsulotomy. Despite these interventions, the IOL remained anteriorly displaced, prompting referral to our institution for further management. Upon presentation, the patient exhibited an intraocular pressure (IOP) of 38 mmHg despite maximal medical therapy; spherical equivalent (SE) was -3.88 diopters. To differentiate pupillary block and establish a definitive diagnosis, laser iridotomy was performed; this resulted in a significant reduction in IOP to 10 mmHg and deepening of the anterior chamber. However, 19 days post-iridotomy, the IOP again increased to 39 mmHg; the SE worsened to -4.88 diopters. Slit-lamp examination and ultrasound biomicroscopy revealed a transparent membrane obstructing the iridotomy site behind the iris, consistent with a complex of disrupted ciliary zonules and the anterior hyaloid. Subsequently, photodisruption of this membrane was performed through the existing iridotomy. This intervention deepened the anterior chamber and achieved a wide-open iridocorneal angle. At the last follow-up, the patient had maintained an IOP of 10 mmHg without glaucoma medication. Furthermore, SE improved to -0.38 diopters, resulting in a best-corrected visual acuity of 1.0. Conclusions Our case demonstrates the development of malignant glaucoma following cataract surgery and subsequent total vitrectomy and laser posterior capsulotomy in a nanophthalmic eye. Thorough irido-zonulo-hyaloidotomy demonstrated to be an effective approach for achieving significant IOP reduction.

This paper discusses a rare case of a 49-year-old female diagnosed with a central nervous systemisolated neoplasm with histiocytic features, classified as histiocytic neoplasm, not otherwise specified (NOS). Despite comprehensive histopathological and genetic studies, accurately diagnosing the case proved challenging. Initial surgical findings and frozen biopsy suggested a low-grade glioma; however, subsequent immunohistochemistry and genetic analysis excluded known histiocytic subtypes such as ALK-positive histiocytosis and Erdheim-Chester disease. The patient’s condition improved following occupational rehabilitation therapy for right upper motor weakness, as well as anticonvulsant and radiation therapy, and her neurological condition remains stable. This case underscores the diagnostic challenges of Histiocytic Neoplasms and the necessity for interdisciplinary collaboration and sophisticated diagnostic techniques.
