The worldwide burden of visual impairment is mostly attributed to ocular diseases, which include alterations of the retina, optic nerve, cornea, and ocular surface. Despite advances in medicine, the prevention and management of these conditions remain challenging, driving ongoing research into novel bioactive compounds. Among these, polyphenols—an assorted group of plant-derived compounds abundant in the human diet—have attracted significant attention due to their potential antioxidant, anti-inflammatory, and immunomodulatory properties. Increasing evidence suggests that polyphenols may help counteract oxidative stress and modulate pathways involved in ocular pathologies, assisting the conventional therapeutic strategies. This narrative review aims to analyze the current evidence about the potential therapeutic effects of the main polyphenols (e.g., curcumin, resveratrol, epigallocatechin gallate) currently recognized for the management of ocular diseases.

Uveal melanoma is the most common primary intraocular malignancy in adults, most frequently arising from the choroid, followed by the ciliary body and iris. Its diagnosis and management require precise characterization of tumor morphology, localization, and associated complications to optimize visual and systemic outcomes. Recent advances in optical coherence tomography (OCT), anterior segment OCT (AS-OCT), and OCT angiography (OCTA) have expanded the ophthalmologist’s ability to non-invasively visualize structural and vascular changes associated with this disease. In fact, enhanced depth imaging (EDI) and swept-source (SS) OCT can provide detailed views of deep ocular structures, enabling early detection of hallmark features such as subretinal fluid, retinal pigment epithelium disruption, and dome- or mushroom-shaped choroidal elevations; AS-OCT improves evaluation of lesions of the anterior segment, revealing iris architecture distortion and angle involvement; OCTA facilitates the visualization of abnormal tumor vasculature and detection of radiation-induced microvascular changes, including capillary dropout and foveal avascular zone enlargement. Moreover, these imaging modalities have demonstrated utility in differentiating uveal melanoma from pseudomelanomas, such as choroidal nevi, hemangiomas, and metastases. The present review aims at objectively assessing the use of OCT and OCTA in the diagnosis, treatment, and follow up of ocular melanoma, emphasizing their crucial role in identifying pathologic biomarkers of this potentially fatal ocular disease.

Background and Objectives: Here, we report the anatomical and functional outcomes of Pars Plana Vitrectomy (PPV) with feeder vessel ligation, with or without endoresection in cases of retinal detachment (RD) secondary to retinal capillary hemangioblastoma (RCH). Materials and Methods: This retrospective observational study included 12 eyes with RD secondary to RCH. Based on the location of the lesion and the features of the RD, eyes were divided into two groups. Seven eyes with RCH located in Zone 2 or Zone 3, associated with tractional retinal detachment (TRD), underwent PPV with feeder vessel ligation and tumor endoresection. Five eyes, either with RCH in Zone 2 or Zone 3 associated with exudative retinal detachment or with RCH in Zone 1 associated with RD, underwent PPV with feeder vessel ligation alone, without tumor endoresection. Outcome measures included local tumor control, best-corrected visual acuity (BCVA), anatomical success, and rates of complications. Results: RCH regressed completely in 100% of eyes with no evidence of recurrence. The mean follow-up was 4.6 years. In the endoresection group, the mean BCVA was 2.18 ± 0.3 logMAR at baseline and 0.95 ± 0.5 logMAR after surgery (p = 0.018), whereas in the second group, the baseline mean BCVA was 1.33 ± 0.2 logMAR and 1.52 ± 0.7 logMAR postoperatively. In the first group, retinal attachment was achieved in all eyes, whereas in the second group, two eyes presented with persistent RD and proliferative vitreoretinopathy (PVR). No cases of phthisis bulbi or neovascular glaucoma were observed. Conclusions: PPV combined with feeder vessel ligation and endoresection appears to be an effective treatment for TRD secondary to RCH located in Zones 2 and 3, providing satisfactory anatomical and visual outcomes considering the severity of the disease. In cases where tumor location precludes endoresection, PPV with feeder vessel ligation alone may still be a viable option, although the potential risk of PVR could persist.

Graft-versus-host disease (GVHD) is a serious complication that may occur in patients receiving allogeneic hematopoietic stem cell transplant (HSCT). GVHD occurs because of the immunological reaction between the donor’s T cells and the recipient’s antigens; GVHD may develop in different tissues, including the eye. Corneal perforation is an uncommon but vision-threatening manifestation of GVHD. We reported the case of a 65-year-old male patient who developed corneal perforation sequentially in both eyes 3 years after receiving HSCT. Conservative treatment with topical steroids and lubricants, bandage contact lens, and lacrimal punctal occlusion surgery resulted in the successful resolution of the corneal perforation with satisfactory visual recovery in the right eye. Therefore, corneal perforation can occur as the presenting manifestation of ocular GVHD. Regular ophthalmological examinations are recommended after HSCT to enable the early diagnosis of ocular GVHD and prompt treatment initiation.
