PURPOSE: To report transient corneal edema after phacoemulsification as a predictive factor for the development of pseudophakic cystoid macular edema (PCME). METHODS: A total of 150 eyes from 150 patients (59 men and 91 women; mean age, 68.0 ± 10.15 years) were analyzed using spectral domain optical coherence tomography 1 week and 5 weeks after routine phacoemulsification cataract surgery. Transient corneal edema detected 1 week after surgery was analyzed to reveal any significant relationship with the development of PCME 5 weeks after surgery. RESULTS: Transient corneal edema developed in 17 (11.3%) of 150 eyes 1 week after surgery. A history of diabetes mellitus was significantly associated with development of transient corneal edema (odds ratio [OR], 4.04; 95% confidence interval [CI], 1.41 to 11.54; p = 0.011). Both diabetes mellitus and transient corneal edema were significantly associated with PCME development 5 weeks after surgery (OR, 4.58; 95% CI, 1.56 to 13.43; p = 0.007; and OR, 6.71; CI, 2.05 to 21.95; p = 0.003, respectively). In the 8 eyes with both diabetes mellitus and transient corneal edema, 4 (50%) developed PCME 5 weeks after surgery. CONCLUSIONS: Transient corneal edema detected 1 week after routine cataract surgery is a predictive factor for development of PCME. Close postoperative observation and intervention is recommended in patients with transient corneal edema.

PURPOSE: To compare the long-term efficacy and safety of intravitreal triamcinolon with or without rescue laser therapy (intravitreal triamcinolone injection [IVTA] group), bevacizumab with or without rescue laser treatment (intravitreal bevacizumab injection [IVB] group), or a combination of both with or without rescue laser therapy (IVTA + IVB group), with standard care for patients with macular edema secondary to branch retinal vein occlusion (BRVO). METHODS: We reviewed the medical records of 151 patients treated with intravitreal injection with or without rescue laser for treatment of macular edema caused by BRVO, and who were followed up at 1, 3, 6, 12, and 24 months. During the observation period, rescue grid laser or repeated intravitreal injection with initial drug was performed if recurrence of macular edema was confirmed. Visual acuity, change in visual acuity, and intraocular pressure were compared in each phase. RESULTS: Totals of 16%, 5.6%, and 0% of participants in the three groups showed significant visual loss of more than three lines of the Snellen chart at last follow-up. The IVTA group was the least effective treatment modality, with statistical significance. The development rates of elevated intraocular pressure were similar among the groups. CONCLUSIONS: Although IVTA yielded effects similar to those of standard grid photocoagulation based on the Standard Care vs Corticosteroid for Retinal Vein Occlusion study, IVB or IVTA + IVB with or without rescue laser treatment resulted in improvement in visual acuity at 24 months after the start of treatment and was associated with few serious adverse side effects. Thus, these approaches could be useful for treating macular edema arising secondary to BRVO.

PURPOSE: To evaluate patients' self-recognition of reduced visual acuity due to recurring macular edema in retinal vein occlusion. METHODS: A retrospective review of medical records of patients who were diagnosed with recurring macular edema secondary to retinal vein occlusion was performed. The proportion of patients who recognized reduced visual acuity due to the recurrence of macular edema and who visited the hospital before the scheduled follow-up date was determined. Parameters including age, sex, diagnosis, visual acuity before recurrence of macular edema, and extent of visual acuity reduction due to recurrence of macular edema were compared in patients who recognized a reduction in visual acuity and those who did not. The proportion of patients who visited the hospital promptly was also determined. RESULTS: Forty eyes of 40 patients were included in the analysis. Sixteen and 24 patients were diagnosed with central retinal vein occlusion and branch retinal vein occlusion, respectively. Twenty-one patients (52.5%) recognized reduced visual acuity due to recurring macular edema. These patients were younger (59.2 +/- 7.6 vs. 64.8 +/- 9.4 years, p = 0.046), had better visual acuity before recurrence of macular edema (0.52 +/- 0.48 vs. 1.02 +/- 0.46, p = 0.002), and exhibited a greater reduction in visual acuity after recurrence of macular edema (0.34 +/- 0.24 vs. 0.14 +/- 0.13, p = 0.003). Only four patients visited the hospital before the scheduled follow-up date, and all of these patients lived relatively close to the hospital. CONCLUSIONS: For prompt treatment of recurring macular edema, more intensive education about the self-estimation of visual acuity is necessary, particularly for elderly patients who have relatively poor visual acuity. In addition, a simple and easy way to identify the recurrence of macular edema at the local clinic should be established for patients who live relatively far from the hospital.

We report a case of cytomegalovirus (CMV) retinitis after intravitreal bevacizumab injection. A 61-year-old woman with diabetic macular edema developed dense vitritis and necrotizing retinitis 3 weeks after intravitreal bevacizumab injection. A diagnostic vitrectomy was performed. The undiluted vitreous sample acquired by vitrectomy was analyzed by polymerase chain reaction and culture. Polymerase chain reaction of the vitreous was positive for CMV DNA. Other laboratory results did not show evidence of other infectious retinitis and systemic immune dysfunction. Human immunodeficiency virus antibodies were also negative. After systemic administration of ganciclovir, retinitis has resolved and there has been no recurrence of retinitis during the follow-up period of 12 months. Ophthalmologists should be aware of potential risk for CMV retinitis after intravitreal bevacizumab injection.

PURPOSE: To compare the efficacy between intravitreal bevacizumab and combination treatment (bevacizumab and macular photocoagulation) for the treatment of diabetic macular edema (DME). In addtion, changes of DME type were researched using optical coherence tomography. METHODS: The present study included 90 eyes with bevacizumab injection and 38 eyes with combination treatment. Using chart records, patients were reviewed until 6 months after treatment. The present study compared changes of visual acuity (VA) and macular thickness at each follow up. DME was classified into 4 types and the morphologic pattern was compared. RESULTS: In patients with the bevacizumab injection only, VA improved from 0.29 +/- 0.18 to 0.48 +/- 0.26 at 1 month and returned to 0.32 +/- 0.20 at 6 months after treatment. In the combination treatment, VA improved from 0.32 +/- 0.22 to 0.52 +/- 0.26 at 1 month and returned to 0.36 +/- 0.18 at 6 months after treatment. There was no significant improvement of VA at the final follow-up with either treatment. There was significant decrease of macular thickness except in the mixed DME type. CONCLUSIONS: The combination treatment did not yield better VA or macular thickness reduction at 6 months than bevacizumab injection alone. By classifying and observing the change of DME type, determining the treatment objectively and predicting the effectiveness of treatment can be helpful.

PURPOSE: To compare the effects of intravitreal bevacizumab to those of triamcinolone acetonide injection for the treatment of macular edema secondary to branch retinal vein occlusion. METHODS: This retrospective study included 50 eyes of 50 patients who received a single injection of intravitreal bevacizumab (1.25 mg/0.05 mL, 22 eyes) or triamcinolone acetonide (4 mg/0.1 mL, 28 eyes) as the only treatment for macular edema secondary to branch retinal vein occlusion; all patients had a post-injection follow-up duration of >24 weeks. Best corrected visual acuity (BCVA), intraocular pressure (IOP), and central macular thickness (CMT) by optical coherence tomography were measured for up to 24 weeks after injection. RESULTS: BCVA was improved at 1, 4, 8,12 weeks post-injection in the bevacizumab group, and at 1, 4, 8 weeks post-injection in the triamcinolone group. No significant difference was found between the two groups except at 12 weeks. CMT decreased significantly within each group, and no significant difference between groups was found. In the bevacizumab group, no elevated IOP was observed, whereas IOP was significantly increased at 4, 8, and 12 weeks after triamcinolone injection; IOP was therefore significantly different between the two groups. CONCLUSIONS: Intravitreal bevacizumab is a comparatively simple treatment method that can effectively improve BCVA and reduce CMT without ocular and systemic complications. Consequently, intravitreal bevacizumab injections may be useful as both an alternative and primary treatment for macular edema secondary to branch retinal vein occlusion.

PURPOSE: To evaluate the effect of different doses of intravitreal triamcinolone acetonide on diffuse diabetic macular edema. METHODS: In a retrospective study, 44 eyes with diffuse diabetic macular edema were treated with an intravitreal injection of 4 mg (n=12 eyes), 8 mg (n=17) or 25 mg (n=15) of triamcinolone acetonide (TA). Optical coherence tomography, best-corrected logMAR visual acuity and Goldmann tonometry were performed at baseline, 1 week, and 1, 3, 6, 9 and 12 months after treatment. Mean follow-up was 9.8 months (standard deviation=2.3) with a range of 5-12 months. RESULTS: The duration of intravitreal TA effects on macular thickness and visual acuity increased with increasing dosage. An observed increase in intraocular pressure induced by TA was not significantly associated with dosage. CONCLUSIONS: In patients with diffuse diabetic macular edema who receive intravitreal TA, effects may last longer after a dosage of 25 mg, than after lower doses of 8 mg or 4 mg.

PURPOSE: To evaluate the characteristics of fluid accumulation in the uveitic stage of Vogt-Koyanagi-Harada (VKH) disease using high resolution optical coherence tomography (OCT3). METHODS: Twenty-eight eyes in 14 patients with VKH disease were reviewed retrospectively. These 28 eyes were divided into 19 eyes with intraretinal fluid (C group) and 9 eyes without intraretinal fluid (N group). Changes in visual acuity and fluid accumulation observed using OCT were compared between the two groups. RESULTS: Visual acuity at the time of presentation was significantly worse in the C group than in the N group (p=0.005). The photoreceptor layer appeared to be double-layered due to a cystoid space in the C group. Layered structures and strands found in the cystoid space. Expanding sponge-form edema led to the development of a cystoid space in the photoreceptor layer. Intraretinal fluid resolved earlier than subretinal fluid. There were no observed differences in visual acuity between the two groups after four days of treatment. CONCLUSIONS: Accumulation of intraretinal fluid was related to poor initial visual acuity, but not to final visual acuity. High resolution OCT findings indicate that edema of the photoreceptor layer participates in the development of a cystoid space.
