Methods: This was a retrospective, interventional, case-series study. Twelve eyes of 12 RVO patients, including 6 eyes with central RVO (CRVO) and 6 eyes with branch RVO (BRVO) were included. The eyes were treated with IVR (0.5 mg) injections and SS injections (20 mg per day, one week consecutively in one month). The outcomes measured included best corrected visual acuity (BCVA), central retinal thickness (CRT), mean defect (MD), pattern standard deviation (PSD), macular light sensitivity of the central 16 points in CRVO group and the central 8 points in BRVO group before and after the treatment. Statistical analyses were then performed on the main outcome measures. Results: An improvement of BCVA was found in all patients after treatment with significant difference (t = 7.74, p p p p > 0.05). All RVO patients had their macular light sensitivity of the involved part improved significantly (t = 5.03, p p p < 0.01). The Pearson’s correlation was calculated among BCVA, MD, macular light sensitivity and CRT. No obvious significance was found between CRT and BCVA outcomes, whereas MD and mean macular light sensitivity outcomes were closely related to BCVA results in the BRVO group and the latter showed a more intimate correlation. No similar correlation was found in RVO and CRVO group. Conclusion: IVR injection and SS injection together could effectively improve the therapeutic effect in RVO patients with ME. Microperimetry could be used as a routine diagnostic test and a possible valuable tool in the follow-up of patients with RVO, especially in BRVO.展开更多

METHODS: All the patients admitted with diagnosis of PIH were included in this study. Age, race, gravida, gestation period, blood pressure, and proteinuria were noted from the case records. After taking history for any eye symptoms, fundus examination was done after dilating the pupils with direct ophthalmoscope in the ward itself. All the findings were noted on a data sheet, and were analyzed using SPSS programme. RESULTS: A total of 78 patients of PIH were examined. Majority (75.6%) were Malays. The mean age of patients was 30.2 years (range 21-45 years). The gestation period ranged from 25 weeks to 41 weeks; 34 (43.5%) were primi gravida. Thirty (38.4%) patients had mild preeclampsia, 46 (59%) had severe preeclampsia and 2(2.5%) had eclampsia. Retinal changes (hypertensive retinopathy) were noted in 46 (59%) patients --- grade I in 41 (52.6%) and grade II in 5 (6.4%). Haemorrhages or exudates or retinal detachment were not seen in any patient. There was statistically significant positive association of retinal changes and blood pressure (P =0.001), proteinuria (P =0.018) and severity of the PIH (P =0.024). CONCLUSION: Retinal changes (grade I and II hypertensive retinopathy) were seen in 59% of patients with PIH and they were significantly associated with blood pressure, proteinuria and severity of the disease. Fundus examination helps in assessing the severity of PIH.展开更多
