A 74-year-old man presented with a three-year history of foreign body sensation in the right eye after cataract surgery. He underwent uneventful trabeculectomy with mitomycin C (MMC) in the right eye seven years ago. Slit-lamp examination revealed a large avascular filltration bleb overhanging on the cornea with a thin base connected to the conjunctiva. Preoperative ultrasound biomicroscopy (UBM) impressions were confirmed by leakage of aqueous from the incision intraoperatively. Surgical dissection and revision of the bleb was performed with satisfactory outcome. Histopathologic evaluation showed proliferation of fibrous tissue under the conjunctival epithelia with irregular cystoids change. The current case may be the first report of a post-trabeculectomy overhanging filtration bleb related to cataract surgery. The possible mechanism may be related to microleakage of the surgical wound after phacoemulsiff cation which initiated the healing and scarring process.

To report the case of a patient who presented with idiopathic choroidal neovascularization (CNV) as the first sign of multiple evanescent white dot syndrome (MEWDS). A 25-year-old woman presented with recent onset of decreased vision and metamorphopsia in the right eye. The results of fundoscopic examination, fluorescein angiography, and optical coherence tomography (OCT) were compatible with a diagnosis of idiopathic CNV, which was treated with one intravitreal injection of bevacizumab. Five years later, the patient returned complaining of photopsia and decreased vision in the same eye. The fundoscopic examination showed typical signs of MEWDS. After 3 months, recurrence of CNV was observed in the same eye. In conclusion, idiopathic CNV might be the only manifestation of a subclinical occurrence of MEWDS. In this case, it was followed by a recurrence of MEWDS and subsequent reactivation of CNV.

We report a case of large graphite foreign body (FB) in the anterior chamber of eye of a 4-yearold child, incurred during unsupervised play. Despite delayed presentation, the eye had few signs of resolved inff ammation which allowed safe extraction of the FB bimanually through limbus. School play, especially in young children, should be under supervision and free of sharp objects. Graphite is inert while inside the eye, and even large pieces can be well tolerated for long time in absence of infection.

Purpose: To investigate the effect of intravitreal injection of basic fibroblast growth factor (bFGF) on activation and proliferation of endogenous retinal progenitor cells in the Royal College of Surgeons (RCS) rat.

Methods: Twenty-four rats were studied after the 30th postnatal day (≥30). Eighteen RCS-p⁺/LAV rats were divided into 3 groups: bFGF-treated, vehicle-treated, and untreated groups randomly, and 6 RCS-ray⁺p⁺/Lav rats were used as normal controls. 6 μl of bFGF (5 μg /10 μl) or vehicle was injected into the vitreous on day 31, 33, and 35 after birth (P31, P33, P35) in the bFGF group and vehicle group respectively, and no injections were administered in the untreated and control groups. All the rats were euthanized, and their eyes were enucleated, hemisected, and fixed at 50 days after birth for immunohistochemistry and measurement of outer nuclear layer thickness.

Results: Nestin and Chx10 were positive in all retinal layers. Intravitreal injection of bFGF in retina-dystrophic RCS (RCS-p⁺/Lav) rats induced intense labeling for the retinal progenitor cell markers Chx10 and Nestin, which were highly colocalized. Fluorescence intensity for both labels was somewhat less in the control rats, and much less in the vehicle-injected rats as well as in the untreated RCS rats. The outer nuclear layer (ONL) was significantly thicker in the bFGF group than that in the vehicle-treated or untreated group (P < 0.01), but thinner than that of the control group (P < 0.01). No significant difference was observed in the ONL thickness between the vehicle group and untreated group (P > 0.05).

Conclusion: bFGF may contribute to the activation of retinal progenitor cells in RCS rats, thus counteracting degeneration by promoting the proliferation of the progenitor cells.
