Background/Objectives: Retinal metastasis (RM) is an exceptionally rare clinical condition, comprising less than 1% of ocular metastasis cases. This study aims to investigate the clinical features of RM originating from systemic carcinoma. Methods: A systematic review (PROSPERO ID: CRD42022344724). Results: The systematic review revealed 58 cases involving 61 eyes. Most of the cases (82.8%) had a known primary malignancy before RM was diagnosed. The main primary sites were the lung (45.8%), gastrointestinal tract (23.7%), and breast (16.9%). The lung was the most common (80.0%) carcinoma in cases with unknown primary sites. The median survival after RM diagnosis was 11 months. The main clinical patterns were patchy retinal infiltrates (35.7%), an elevated retinal mass (63.8%), and punctate retinal infiltrates (7.1%). Subretinal fluid, vitreous seeding, and choroidal invasion were noted in 57.4%, 41.0%, and 6.6% of eyes, respectively. Key multimodal imaging features were early hypofluorescence with mid-to-late hyperfluorescence on fluorescein angiography (84.6%) and hyper-reflectiveness on optical coherence tomography (70.8%). A final best-corrected visual acuity of ≤20/200 was noted in 66.7% of the eyes. Conclusions: Patchy retinal infiltrates, an elevated retinal mass, and punctate retinal infiltrates are the major clinical patterns of RM from systemic carcinoma. The primary carcinoma sites are the lung, gastrointestinal tract, and breast. Systemic and visual prognoses were unfavorable.

Background and Objectives: Our study compared the visual and anatomical outcomes of polypoidal choroidal vasculopathy (PCV) patients receiving intravitreal aflibercept (IVA) with or without photodynamic therapy (PDT) over 12 months. Materials and Methods: This retrospective study was performed for 60 eyes from 60 patients with treatment-naïve PCV. Thirty eyes were treated using IVA monotherapy (IVA group), and thirty eyes were treated using a combination of IVA with PDT (IVA/PDT group). The baseline characteristics, treatment outcomes, and retreatment rates were compared between the two groups over a one-year follow-up period. Results: The best-corrected visual acuity (BCVA) was found to have improved significantly in the IVA/PDT group at every 3-month visit. However, no significant BCVA improvement was observed in the IVA group. A significantly lower retreatment rate and higher dry macula rate were found in the IVA/PDT group than that in the IVA group. In the entire population of the study, a better baseline vision and younger age were associated with better final visual outcomes. Retreatment was associated with poor baseline BCVA and IVA monotherapy. Conclusions: The combination of IVA and PDT may offer superior visual improvement and a higher dry macula rate compared to IVA monotherapy in the treatment of PCV patients while requiring fewer retreatments over 12 months.
