One patient with bilateral acute retinal necrosis underwent encircling scleral buckle, vitrectomy, and intravitreal acyclovir on both eyes. This procedure was performed on the right eye while the retina was attached. The retina of the right eye was reattached by performing fluid-gas exchange and modified panretinal photocoagulation when the retina subsequently detached. Soon after the development of retinal detachment in the left eye, the above surgical procedures were performed on the left eye, and the retina was successfully reattached.Bilateral acute retinal necrosis with significant vitreous opacification, which is a devastating ocular disease causing possible blindness in both eyes, requires more aggressive, early surgical management.

A 47 year old male patient visited our hospital with the chief complaint of deterioration of the visual acuity in the left eye. The fundus examination revealed thick hard exudates, multiple aneurysms and telangiectasias of the retinal vessels in the posterior pole. Fluorescein angiography demonstrated massive leakage over an area of the aneurysms. Optical coherence tomography (Stratus OCT; Zeiss-Humphrey, Dubin, CA) revealed diffuse and marked thickening of the retina. Laser photocoagulation was performed under the diagnosis of Coats' disease. However, the treatment could not be performed satisfactorily. On the first and 6th weeks, an intravitreal injection of bevacizumab and triamcinolone acetonide was administered, and laser photocoagulation was again attempted. The effectiveness of eachagent on retinal edema was evaluated at the follow-up performed at 1, 2, 5, 7, 10 weeks and 6 months after the injection. At one week after the intravitreal bevacizumab injection, there was no improvement. An intravitreal injection of triamcinolone acetonide was performed 6 weeks after the initial diagnosis,which resulted in a reduction in the thickness of the macular edema. Therefore, laser photocoagulation was performed sufficiently on telangiectasias. The follow-up at 6 months showed a relative increase in the macular edema, but there was reduced leakage from the telangiectasias compared with the previous angiograph.

A 37-year-old female, who had received modified radical mastectomy for cancer of her right breast, presented with decreased visual acuity in the left eye after radiation therapy for the management of the metastasis to her right brain 14 months ago. After ocular examination, we diagnosed her as radiation retinopathy. At the time of the first visit, the corrected best visual acuity was 0.4 in the left eye, and fundus examination revealed cotton wool spots and cystoid macular edema (CME). The findings in the right eye were normal except for cotton wool spots in the superior major arch. Fluorescein angiography (FA) showed marked telangiectasia and microaneurysms in her left eye but tiny microaneurysms in her right eye. Subsequent optical coherent tomography (OCT) showed CME. We injected intravitreal triamcinolone acetonide (TA). Two weeks after treatment, the visual acuity was improved to 0.6 and the retinal thickness was decreased. Three months later, the visual acuity in the left eye was dropped to 0.3 due to the recurrence of CME, so we injected intravitreal TA again. Five months later, visual acuity was improved to 0.5 and OCT revealed the improvement of CME. The incidence of radiation retinopathy is higher in the side nearer to radiation, but careful radiation blocking is also required on the opposite side of irradiation site considering the possibility of radiation retinopathy and careful observation is required on both sides of the eyes when performing fundus examination.
