Résumé

Context: Ocular complications due to diabetes mellitus (DM) were on the rise despite good literacy levels in South India. Aims: To assess the knowledge and attitude toward DM and diabetic retinopathy of the general population in a suburban town of South India. Settings and Design: Door‑to‑door population survey in suburban town of South India in May 2013. Materials and Methods: A 30‑point questionnaire was prepared and the data were collected and analyzed to determine statistically the knowledge, attitude, and practice (KAP) scores of the general and diabetic population and also to determine significant demographic associations. Results: In this study, 6211 people (3528 [56.8%] women and 2683 [43.2%] men) with a mean age of 55.6 ± 11.7 years (range 21–98 years) were included. Good knowledge and positive attitude were observed in 3457 (55.6%) and 3280 (52.8%) people. Among 1538 (25.4%) people known to have DM, only 619 (40.7%) had good knowledge, 828 (53.8%) had a positive attitude, and 886 (57.6%) had good practice patterns. Although half of them followed general diabetic care, only 9.6% had undergone screening for retinopathy. Literacy showed a significant association with good KAP (P < 0.001 each) in general population and those with DM. Overall, women had significantly better knowledge (P < 0.001). Conclusions: Better literacy, especially among women, is contributory to better public awareness; however, the trend for poor practice patterns needs to be radically changed with aggressive public motivation emphasizing on the necessity of retinopathy screening and periodic follow‑ups.

Résumé

Choroidal osteoma is a usually unilateral benign tumor of the choroid composed of mature bone. Optical coherence tomography (OCT) has been used to image osteoma for several years. With the advent of enhanced depth imaging (EDI) feature of spectral‑domain OCT (SD‑OCT), better visualization of the morphology of choroidal lesions has been possible. Herein we present a case of choroidal osteoma in a 45‑year‑old woman, wherein in vivo morphology of the choroidal osteoma had been visualized using EDI technique of SD‑OCT before and after performing photodynamic therapy. EDI OCT has proven to be a valuable noninvasive imaging modality, almost comparable to histopathological examination, for diagnosing choroidal osteomas and for providing an insight into the in vivo micromorphological changes occurring during the course of the disease.

Résumé

Aim: To provide the normative data of macular and retinal nerve fiber layer (RNFL) thickness in Indians using spectral domain OCT (Spectralis OCT, Heidelberg Engineering, Germany) and to evaluate the effects of age, gender, and refraction on these parameters. Design: Observational, cross‑sectional study. Materials and Methods: The eyes of 105 healthy patients aged between 20‑75 years, with no ocular disease and best corrected visual acuity of 20/20, were scanned using standard scanning protocols by a single examiner. Exclusion criteria included glaucoma, retinal diseases, diabetes, history of prior intraocular surgery or laser treatment. The mean macular and RNFL thickness were recorded, and the effects of age, gender, and refraction on these parameters were evaluated. This data was compared with published literature on Caucasians to assess the ethnic variations of these parameters. Results: The normal central foveal thickness in healthy Indian eyes measured using Spectralis OCT was 260.1 ± 18.19 μm. The nasal inner quadrant showed maximum retinal thickness (338.88 ± 18.17 μm).The mean RNFL thickness was 101.43 ± 8.63 μm with maximum thickness in the inferior quadrant. The central foveal thickness showed a gender‑based difference (P = 0.005) but did not correlate significantly with age (P = 0.134), whereas the parafoveal, perifoveal thickness, macular volume, and RNFL thickness showed significant negative correlation with age. Conclusions: Our study provides the normative database for Indians on Spectralis OCT. It also suggests that age should be considered while interpreting the macular thickness and RNFL, whereas gender should also be given consideration in central foveal thickness.

Résumé

Aims: To present the clinical, indocyanine green angiography (ICGA) features and results of treatment for polypoidal choroidal vasculopathy (PCV) in Indian patients by a retrospective chart review. Materials and Methods: Forty five patients with PCV underwent complete ocular examination, fluorescein angiography (FFA) and ICGA. Treatment was advised for patients with macular involvement and progressive loss of visual acuity. Demographic data, clinical features and results of treatment were analyzed. Results: Mean age at presentation was 61.06 years. Mean follow up was 18 months. The disease was more prevalent in males. Forty three patients had unilateral disease. The most common location of polyps in ICGA was subfoveal (42.5%). Exudative form was seen in 34 of the 47 eyes and the remaining 13 eyes had a hemorrhagic presentation. Thirty four eyes underwent treatment which included thermal laser (n = 11), photodynamic therapy (PDT) (n = 11) and transpupillary thermo therapy (TTT) (n = 12). Statistical analysis was done using the Chi-square test. Subgroup analysis of visual outcome following various modalities of treatment showed that the results of PDT (P < 0.001) and thermal laser (P < 0.001) were statistically significant. Conclusions: PCV is an important differential diagnosis in patients presenting with serosanginous maculopathy and submacular hemorrhage. The disease was more prevalent in males and was unilateral in the Indian population. Timely intervention in cases with symptomatic polyps could achieve stabilization of visual acuity. Thermal laser and PDT were safe and effective.
