Adequate training of ophthalmologists in treating DR and improvement in eye-care infrastructure are needed to tackle this major public health problem in India.
Aim To evaluate transpupillary thermotherapy (TTT) for the treatment of subfoveal focal leaks in central serous chorioretinopathy (CSC). Methods The patients presenting with long-standing CSC, but without the features of chronicity, were offered the options of TTT, photodynamic therapy (for subfoveal leaks), photocoagulation (for extrafoveal leaks), or observation. The patients who opted for TTT or observation were enrolled in this study. TTT was performed using a spot diameter of 0.5 mm for 1 min. Best-corrected visual acuity (BCVA), status of macular detachment, and fluorescein angiographic status were evaluated at 1, 3, and 6 months. Results This study included 39 patients (40 eyes) with CSC between 4 and 12 months, of whom 25 patients (25 eyes) opted for TTT for subfoveal leaks. Fourteen patients (15 eyes) were followed up without treatment. The groups were comparable in age, sex, and baseline BCVA. Minimum follow-up was 6 months. Within 3 months, TTT resulted in the resolution of the serous detachment in 24 (96%) eyes with a single session; one eye required a repeat treatment. Eight control eyes demonstrated persisting CSC at the last follow-up. Visual acuity improved in 23 (92%) treated and five (33%) control eyes; the difference in outcome was statistically significant (Po0.001). One case developed choroidal neovascularization, which resolved with visual recovery to 20/20 after repeat-TTT. Conclusion TTT resulted in the resolution of CSC with subfoveal angiographic leaks with significant improvement in visual outcome, in comparison to the natural history of persistent CSC.
The association between serous retinal detachment of macula (SRD) in hypertensive retinopathy (HTR) and malignant hypertension has been reported. This cross-sectional study included 14 consecutive patients on treatment for hypertension, who were referred for ophthalmic evaluation and were found to have macular SRD, documented by optical coherence tomography. All underwent systemic evaluation for hypertensive status and to rule out other associated/similar diseases such as diabetes, coagulopathies, lupus etc. The mean age of the patients was 44.35 +/- 15.5 years; the mean best-corrected visual acuity was 6/12. All had grade 3-4 HTR; 10 patients had bilaterally symmetrical retinopathy (grade 3 or 4); 4 had asymmetric fundus changes. Systemically, every patient was found to have malignant hypertension. The mean systolic and diastolic pressures were 208.57 +/- 32.78 and 117.86 +/- 14.2 mm Hg, respectively. SRD predicted malignant hypertension more consistently than papilledema (P = .0132). The presence of macular SRD in a hypertensive patient may serve as an indicator of malignant hypertension.
Purpose:
To present clinical profile and risk factors of sight-threatening diabetic retinopathy (STDR) among people with age of onset of diabetes (AOD) <25 versus ≥25 years.
Methods:
A retrospective chart analysis of consecutive patients with diabetic retinopathy (DR)
n
= 654) treated at 14 eye care centers across India between 2018 and 2019 was performed. Patients were divided into two groups, Group 1: AOD <25 years and Group 2: AOD ≥25 years. DR and diabetic macular edema (DME) were classified using the International Clinical Classification of DR severity scale. STDR included severe nonproliferative DR (NPDR), proliferative DR (PDR), and moderate to severe DME. A multilevel mixed-effects model was used for comparison between two groups: 1) Patients with DR and AOD <25 years and 2) Patients with DR and AOD ≥25 years. Bivariate and multivariate regression analyses were used to evaluate risk factors between the two groups.
Results:
A total of 654 patients were included, 161 (307 eyes) in AOD <25 and 493 (927 eyes) in AOD >25 group. There was a higher prevalence of PDR with high-risk characteristics in AOD <25 group (24% vs. 12%) at baseline and 12-month follow-up (25% vs. 6%);
P
< 0.001. Systolic hypertension and poor glycemic control were risk factors in both groups, with no difference in these modifiable risk factors between groups.
Conclusion:
People with youth-onset DM are likely to present with severer form of STDR despite similar modifiable risk factors. Therefore, strict control of systolic blood pressure, glycemic status, and regular screening for DR are recommended to reduce the risk of STDR irrespective of the age of onset of diabetes.
