To report the role of early vitrectomy and silicone oil tamponade in acute endophthalmitis following intravitreal injection. Medical records of eight patients who presented with acute endophthalmitis after intravitreal injection of different drugs were retrospectively reviewed. Initial treatment consisted of vitreous tap with cultures and injection of intravitreal antibiotics, with the patients subsequently undergoing pars plana vitrectomy and silicone oil tamponade within 24 h following initial vitreous tap. The mean time to presentation was 1.7 days (1-3 days). The initial best-corrected visual acuity was hand motion to 0.05 before treatment and 0.05-0.8 (Snellen) after treatment. Vitreous cultures were obtained from all patients, of which four were culture positive. Endophthalmitis was controlled in all patients. There was no retinal detachment or phthisis bulbi during the follow-up period (1-4 years). Acute endophthalmitis following intravitreal injection occurs rapidly and requires urgent treatment. If intravitreal antibiotics fail to control inflammation, early pars plana vitrectomy and silicone oil tamponade would be an appropriate option.

Combined vitreoretinal surgery and phacoemulsification is safe and effective in treating vitreoretinal abnormalities coexisting with cataract in diabetic and nondiabetic patients. Diabetic patients should be monitored more carefully for fibrinous uveitis and posterior synechia in the early postoperative period and for posterior capsular opacification in the late postoperative period.

Objectives:Ophthalmologic disease in patients with acute leukemia occurs due to primary leukemic infiltration (involvement), or secondary to the disease and its treatment. In recent years the life expectancy of acute leukemia patients has increased with the advent of modern therapies. The present study aimed to determine the incidence of ocular manifestations in children with acute leukemia.Materials and Methods:The study included 120 patients diagnosed with acute leukemia at Başkent University Hospital, Pediatric Hematology Department between 1995 and 2010. All the patients were examined by an ophthalmologist via direct and indirect ophthalmoscopy.Results:Among the patients, 83 (69.2%) were diagnosed with acute lymphoblastic leukemia, 35 (29.1%) with acute myeloblastic leukemia, and 2 (1.7%) with mixed-lineage leukemia. In all, 58 ophthalmic manifestations were noted in 41 patients (34.2%). In our patients, 12 ophthalmologic involvements were present at admission and 46 ocular findings occurred during follow-up. The incidence of these manifestations increased with age.Conclusion:Ophthalmologic manifestations were not correlated with gender, hematological parameters at disease onset, type of leukemia, or the frequency of relapse and survival. To more clearly determine the effect of ophthalmologic manifestations on the prognosis of leukemia, larger scale and multi-center studies are needed.

Neodymium:YAG laser capsulotomy in patients with PCO associated with late CBS increased visual acuity without a significant change in refraction or IOP. Capsular block syndrome may be asymptomatic and remain undiagnosed for a long time after cataract surgery before PCO develops.
