Scleral Fixated Secondary IOLs: An Outcomes Comparison Between the Yamane and Gore-Tex-Sutured Techniques.

BACKGROUND AND OBJECTIVE: Among secondary intraocular lens (IOL) techniques, scleral fixated IOLs (SFIOLs) offer advantages in cases without capsular support. In this article, we compare outcomes between two types of Gore-Tex scleral sutured IOLs with the Yamane technique. PATIENTS AND METHODS: This study was a retrospective chart review of patients who underwent SFIOL implantation. RESULTS: Analysis revealed a statistically significant improvement in final postoperative visual acuity (VA) for sutured SFIOLs (P < 0.001, Envista (n = 29) 95% CI 0.47-1.04, Akreos (n = 23) 95% CI 0.32-0.81) with no statistical improvement in the Yamane group (P = 0.44, n = 15, 95% CI -0.33-0.71). Outcomes analysis revealed greater incidences of cystoid macular edema (CME) in the Yamane cohort (P < 0.05) and a higher rate of reoperations in the Akreos cohort (P < 0.02). All complications related to suture material (n = 4) and IOL decentration (n = 2) occurred in the sutured SFIOL group. CONCLUSIONS: The sutureless Yamane technique offered fewer subsequent surgeries and suture-specific complications while revealing diminished VA improvement in long-term follow-up compared to the sutured SFIOLs.

Pembrolizumab-Induced Nodular Posterior Scleritis.

Purpose: To report a case of painless posterior scleritis presenting as a choroidal nodule in a patient with history of a tumor being treated with pembrolizumab. Methods: A case and its findings were analyzed, and a relevant literature review was performed. Results: A 20-year-old woman with a history of ependymoma presented with painless blurred vision in the right eye after being started on pembrolizumab for a tumor recurrence. Fundoscopy showed a solitary amelanotic choroidal lesion with surrounding subretinal fluid in the affected eye. Ultrasonography showed moderate internal reflectivity and fluid in Tenon capsule consistent with nodular posterior scleritis. After a course of systemic steroids and discontinuation of the pembrolizumab, the choroidal lesion completely resolved. Conclusions: Clinicians should be aware of posterior scleritis as an ocular complication of this class of medications.

Optical Coherence Tomography Angiography Microvascular Variations in Pre- and Posttreatment of Retinoblastoma Tumors.

INTRODUCTION: The purpose of this study is to describe variations in microvasculature before and after treatment of treatment-naive lesions and during consolidation therapy of retinoblastoma lesions using an investigational portable optical coherence tomography angiography (OCTA) system. METHODS: This study is a single-center, prospective, observational case series. Recruited subjects were either undergoing surveillance for retinoblastoma or had newly detected retinoblastoma. Nine tumors from 7 eyes in 6 patients were included. During exams under anesthesia, the tumors were imaged with an investigational portable OCTA system. OCTA images were analyzed to assess vascular changes before and after treatment. RESULTS: In all 6 presented cases, OCTA imaging revealed distinctive vascular patterns, such as dilated feeder arteries and draining veins, disorganized and complex branching patterns, irregular vessel calibers, and dilation and tortuosity of vessels. After treatment, OCTA imaging revealed decreased intrinsic tumor vascularity and reduced dilation of draining and feeder vessels. Tumor relapse demonstrated prominent vascularity (n = 1) that resolved on repeat OCTA after transpupillary thermotherapy treatment. Type 2 (n = 1), 3 (n = 6), and 4 (n = 1) tumor regression patterns were seen in our patients after treatment, and OCTA findings were consistent with a previously published report. Interestingly, in one of the presented cases, OCTA demonstrated clear feeder, draining, and intrinsic tumor vessels that were not as evident on fluorescein angiography. CONCLUSIONS: OCTA may offer a noninvasive and sensitive technique to evaluate the vasculature of both the tumor and the surrounding retina in retinoblastoma. With additional research and development into its use in patients with retinoblastoma, OCTA may one day be useful in assessing treatment response and residual tumor activity.

Choroidal nevus with retinal invasion, clinical and imaging features.

PURPOSE: To report a clinically challenging case of a choroidal nevus with retinal invasion with accompanying ancillary testing. OBSERVATIONS: A 60-year-old Caucasian female was referred for a suspicious melanocytic choroidal lesion in her left eye. Ophthalmoscopic examination revealed a melanocytic choroidal lesion, measuring 10 mm × 10 mm in basal diameter. The lesion had a clinically evident area of retinal invasion seen as a protruding choroidal mass at its center, darker in appearance compared to the rest of the lesion, obscuring retinal vessels. The choroidal nevus had associated chronic retinal changes and the absence of overlying orange pigment or subretinal fluid. On fundus autofluorescence, there was a hypoautofluorescent area showing the site of retinal invasion. Fluorescein angiography at the lesion site exhibited central blocked perfusion corresponding to the area of retinal invasion. Ultrasonography showed a dome-shaped choroidal lesion that was optically dense with a medium-high internal reflectivity measuring 3.3mm in thickness. The optical coherence tomography showed a choroidal mass extruding through a break in Bruch's membrane with inner retinal invasion. A watchful waiting strategy was adopted, and at 28 months follow-up, the choroidal lesion did not show growth or presence of new suspicious features of malignant transformation. CONCLUSION AND IMPORTANCE: This case highlights the importance of recognizing the key features of choroidal nevi with retinal invasion, which can prevent the treatment of a benign condition and assist in the arrival of a correct diagnosis. These lesions should be monitored for long-term.

Intravitreal Voriconazole for the Treatment of Cryptococcus neoformans Endogenous Endophthalmitis.

Background: Cryptococcus neoformans is an encapsulated yeast that can cause fungemia and, in rare instances, lead to endogenous fungal endophthalmitis. No standard of care has been established to treat fungal endophthalmitis when systemic antifungal treatment fails to resolve the intraocular infection. Intravitreal voriconazole has been used for the treatment of fungal endophthalmitis caused by a broad range of fungal pathogens, and a limited number of reports have shown the efficacy of using intravitreal voriconazole for C neoformans endophthalmitis. We report a case of endogenous fungal endophthalmitis caused by C neoformans that was responsive to intravitreal voriconazole. Case Report: A previously healthy 57-year-old male diagnosed with primary neuroendocrine lung tumor developed endogenous endophthalmitis from C neoformans. The endophthalmitis was resistant to intravenous amphotericin B treatment but was responsive to intravenous fluconazole in one eye and was apparently more responsive to intravitreal voriconazole in the other eye. Conclusion: Intravitreal voriconazole should be considered for the treatment of cryptococcal endophthalmitis.
