RESUMO

PURPOSE: To evaluate the factors that are significant in progression to neovascular glaucoma in patients with proliferative diabetic retinopathy. METHODS: In this retrospective analysis, we reviewed the medical records of 52 patients who were first diagnosed with proliferative diabetic retinopathy from March 2014 to March 2016. We compared diabetes mellitus period, HbA1c, chronic diseases such as hypertension, hyperlipidemia, and kidney disease, insulin treatments, blood urea nitrogen, blood creatinine, glomerular filtration rate, urine albumin, dialysis, corrected visual acuity at the first visit, traction membrane sign of the retina at the first visit, vitreous hemorrhage and preretinal hemorrhage in each group and then investigated the prognostic factors of neovascular glaucoma. RESULTS: A total of 52 patients were included in the investigation, 12 patients (23.08%) were diagnosed with iris neovascularization and 4 patients (7.69%) developed neovascular glaucoma. The patients without iris neovascularization were defined as Group I, those with iris neovascularization as Group II, and those with neovascular glaucoma as Group III. The diabetes mellitus period was significantly longer in Group II (10.88 ± 7.14 years) and in Group III (11.75 ± 8.61 years) than Group I (8.30 ± 5.25 years) (p-value 0.41, 0.032, respectively). The HbA1c level was 9.59 ± 2.23 in Group II and 9.27 ± 2.54 in Group I. There was no significant difference between the two groups (p = 0.721). However, HbA1c was significantly higher in Group III (11.55 ± 0.21) than Group I (p-value 0.048). CONCLUSIONS: A long diabetes mellitus period and high HbA1c level have a significant effect on the progression to neovascular glaucoma in patients with proliferative diabetic retinopathy. This information could be useful for predicting and preventing the prognosis of patients.

RESUMO

PURPOSE: We investigated systemic risk factors for clinically significant macula edema (CSME) within 1 year after pan-retinal photocoagulation in patients with proliferative diabetic retinopathy. METHODS: A retrospective chart review was performed on 171 patients who received pan-retinal photocoagulation at our hospital from January 2010 to December 2016. The patients were divided into Group Ⅰ with CSME (85 eyes) and Group II without CSME (86 eyes). The associations between presence of CSME and glycated hemoglobin (HbA1c), duration of diabetes, systolic and diastolic blood pressure (BP), body mass index (BMI), lipid status, sex, and estimated glomerular filtration rate (eGFR) were evaluated. RESULTS: In the present study of 171 patients, there was no significant difference in age and gender distribution between the two groups. Duration of diabetes, total serum cholesterol, serum low density lipoprotein, HbA1c, and eGFR were significantly higher in patients with CSME (p < 0.05). Serum high-density lipoprotein, triglycerides, BMI, and systolic and diastolic BP showed no correlation with CSME. Multiple logistic regression analysis showed that total serum cholesterol and HbA1c values had significantly high odds of developing CSME. CONCLUSIONS: HbA1c, total serum cholesterol, and eGFR are important risk factors associated with CSME in patients with proliferative diabetic retinopathy secondary to pan-retinal photocoagulation. Thus, early detection of these risk factors and their control have significant roles in preventing the development and progression of maculopathy and thereby preventing severe visual loss.

RESUMO

PURPOSE: For vitreous hemorrhage induced by coats-types retinitis pigmentosa, we report a case treated with pars plana vitrectomy and endolaser photocoagulation. CASE SUMMARY: A 24-year-old male who was diagnosed with retinitis pigmentosa in both eyes 6 years earlier presented with decreased visual acuity in his left eye for the last 7 months. Corrected visual acuity was measured at 0.06 in the left eye and fundus examination revealed a vitreous hemorrhage in the left eye as well as an exudative lesion in the right eye's peripheral retina, which suggested Coats-type retinitis pigmentosa. The left eye was treated with pars plana vitrectomy. After removal of the vitreous hemorrhage, endolaser photocoagulation was performed around the peripheral exudative lesion that caused the vitreous hemorrhage. One month later, the best-corrected visual acuity increased to 0.20 in the left eye, and there was an improvement in the vitreous hemorrhage and the exudative lesion. CONCLUSIONS: Pars plana vitrectomy and endolaser can be helpful in vitreous hemorrhage induced by coats-type retinitis pigmentosa.

RESUMO

PURPOSE: To report a case of macular infarction following intravitreal triamcinolone injection for treatment of central retinal vein occlusion. CASE SUMMARY: A 75-year-old male visited our clinic for visual disturbance in his left eye and was diagnosed with macular infarction in his right eye. His medical history included type 2 diabetes, alcoholic liver cirrhosis, and hepatocellular carcinoma. After fundus examination, the patient was diagnosed with central vein occlusion with macular edema and intravitreal triamcinolone was administered to reduce edema. Within 1 week of treatment with the intravitreal injection, the patient experienced a significant decrease in visual acuity. Fluorescein angiogram showed an enlargement of the foveal avasacular zone, although optical coherence tomography (OCT) showed a decreased macular edema. Despite normalization of macular thickness on OCT and cessation of leakage on angiography, visual acuity remained at the same level during 2 months of follow-up. CONCLUSIONS: Intravitreal anti-vascular endothelial growth factor injection as well as intravitreal triamcinolone injection can cause macular ischemia which should be considered with the adopted treatment regimen for patients with ischemic risk factors.

RESUMO

PURPOSE: To compare the 1-year outcome of 1.8 mm and 2.2 mm microcoaxial cataract surgery (MCCS) versus 2.75 mm conventional cataract surgery (CCS). METHODS: The present study evaluated 120 eyes (40 eyes in each group). The mean ultrasound power, ultrasound time (UST), and cumulative dissipated energy (CDE) were measured preoperatively and at 1 day, 1, 2, 6 months, and 1 year postoperative. Visual acuity, number of corneal endothelial cells, and surgically induced astigmatism (SIA) were compared. RESULTS: In LOCS III NO4, 1.8 mm MCCS showed a statistically higher ultrasound time (p-value = 0.031) and CDE (p-value = 0.029), and the day 1 corneal thickness increase was relatively higher in 1.8 mm MCCS (p-value = 0.043) than other two groups. There were no differences in postoperative 1 year visual acuity or number of corneal endothelial cells among the groups. SIA was significantly lower in 1.8 mm and 2.2 mm MCCS compared to that of the conventional treatment (p-value = 0.046). CONCLUSIONS: There were no differences in postoperative 1 year mean endothelial cell density or corrected visual acuity between 1.8 and 2.2 mm MCCS and CCS at all cataract densities. The 1.8 mm and 2.2 mm MCCS techniques were as safe and effective as CCS, and SIA in 1.8 mm and 2.2 mm MCCS was significantly lower than that of CCS.

RESUMO

PURPOSE: To evaluate the factors affecting corneal endothelial cell loss after penetrating keratoplasty in a long-term follow-up. METHODS: Donor age, post-mortem time, storage time, underlying disease, elevation of IOP after surgery, underlying glaucoma, and trephine size were analyzed in 76 eyes. Postoperative corneal endothelial density was measured after 1, 3, 6, and 12 months. Patients who experienced graft rejection were excluded. RESULTS: Donor age and endothelial loss were correlated in all patients (t-value = 1.98); however, post-mortem time and storage time were not statistically significant (t 2 < 2). Endothelial cell loss was more severe in the bullous keratopathy patient group than it was in the keratoconus patient group, but this difference was not statistically significant (p-value = 0.154). The number of anti-glaucomatous eye drops showed positive correlation with the declining rate of endothelial cells (t-value = 1.975). Existence of glaucoma diagnosed before surgery did not statistically influence endothelial cell loss. Additionally, in the bullous keratopathy patient group, an inverse correlation between endothelial cell loss and trephine diameter was observed (t-value = -2.859). CONCLUSIONS: Old donor age, small trephine size in bullous keratopathy, and post-operative IOP elevation are risk factors for increased endothelial cell loss following penetrating keratoplasty.
