Changes in the retinal vascular network morphology (diameter and tortuosity) after administration of intravitreal bevacizumab in a patient with ischaemic branch retinal vein occlusion.

We report a case of transient reduction in the diameter and tortuosity of an occluded vessel after intravitreal administration of 1.25 mg (0.05 ml) bevacizumab in a patient with ischaemic branch retinal vein occlusion. A 64-year-old hypertensive female presented with chief complaints of reduced vision in her right eye for 3 months. Her vision in the right eye was evaluated as counting fingers at 2 m. Fundus examination revealed superotemporal branch retinal vein occlusion. On fluorescein angiography, in the superotemporal quadrant, there was hyperfluorescence that increased in size and intensity in the late phase, suggestive of a leaking neovascular frond. In addition, there was capillary non-perfusion in the adjacent area. The patient was administered 1.25 mg (0.05 ml) of bevacizumab intravitreally in her right eye, under all aseptic precautions. After 1 week, her right eye fundus showed regression of neovascularisation. Fluorescein angiography also demonstrated regression of neovascularisation in addition to a decrease in the diameter and tortuosity of the retinal vessel.

Cytomegalovirus retinitis in a seronegative patient with systemic lupus erythematosus on immunosuppressive therapy.

AIM: The purpose of this study is to report a rare case of cytomegalovirus (CMV) retinitis in a seronegative patient with systemic lupus erythematosus (SLE) on immunosuppressive therapy. METHODS: A seronegative patient with SLE who was on immunosuppressive therapy developed CMV retinitis. The immunosuppressive therapy was tapered, and the patient was given intravitreal ganciclovir and foscarnet in addition to systemic ganciclovir. The follow-up visits were documented. RESULT: The patient responded to the treatment and there was complete resolution. CONCLUSION: CMV retinitis is a rapidly progressive condition and patients on immunosuppressive therapy should be referred to an ophthalmologist for periodic check-up for early diagnosis and treatment of this devastating ophthalmic condition. For clinically resistant CMV retinitis in seronegative patients with SLE, a combination therapy of intravitreal foscarnet with oral and intravenous ganciclovir is useful.
