BACKGROUND The aim of the study is to-1. Diagnose strabismic, anisometropic and mixed amblyopia in age group 5-15 years. 2. Analyse these patients for age, sex, type of refractive error, type of squint, type of fixation pattern and classify them aetiologically. 3. Study effectiveness of different amblyopia treatments in this age group. MATERIALS AND METHODS Patients in 5-15 years of age in a period of two years were selected and assessed for amblyopia, which included a detailed history, visual acuity, retinoscopy, ocular movements and alignment, slit lamp examination, fundus examination. Patients were given amblyopia treatment and assessed for improvement. Settings and Design-Hospital-based descriptive study in a period of two years. RESULTS In 32 amblyopic patients, maximum patients were of age group between 5-7 years. 53.12% of patients were females. Amblyopia was predominant among anisometropic patients (75%) with maximum of refractive error difference between 2.00 D to 4.00 D. Amongst them, maximum amblyopes were having hypermetropia with astigmatism (37.50%). In the strabismic type, esotropia was more common. Patients showing more than 2 Snellen's line improvements after patching for 2 hrs. were 77.27% and for 6 hrs. were 22.72%. After part-time patching, maximum improvement in BCVA (best corrected visual acuity) was seen in anisometropes (P<0.0001) followed by strabismic (P=0.025) and least with mixed (P=0.026) amblyopes. CONCLUSION Amblyopia is treatable if detected earlier. Lack of community or preschool vision screening was the main cause for late pickup of amblyopic children for timely management and hence significant visual impairment associated with the condition.
BACKGROUND Fundus fluorescin angiography (FFA) has been traditional gold standard for detection of cystoid macular oedema (CME) but nowadays optical coherence tomography (OCT) is used more often by to detect CME due to various conditions. Although FFA can assess CME qualitatively, OCT provides quantitative measurement of foveal thickness. The purpose of this study is to compare sensitivity of FFA and OCT for detection of CME and know the etiological distribution of CME and the ability of FFA and OCT in diagnosing CME in different aetiologies. METHODS A hospital based prospective observational diagnostic study was conducted in tertiary eye care centre in central India on 143 eyes of 103 patients. FFA and OCT findings in patients of CME diagnosed provisionally on fundus examination were studied. RESULTS Of total 103 patients studied, maximum patients 20 (19.42 %) were in age group of 55 - 59 years whereas minimum 6 (5.83 %) were in age group of 40 - 44 years. In 103 patients, 61 (59.22 %) were males and 42 (40.78 %) were females. Both eyes were involved in 41 (40.78 %) cases. Most common cause of CME was nonproliferative diabetic retinopathy (NPDR) 52 eyes (35.86 %), followed by branch retinal vein occlusion (BRVO) 32 eyes (22.06 %), then proliferative diabetic retinopathy (PDR) 14 eyes (9.6 %), central retinal vein occlusion (CRVO) 13 eyes (8.96 %). CME on OCT was seen in maximum of retinal vein occlusion patients - CRVO (84.61 %) and BRVO (84.37 %). Of 145 eyes, 114 (78.32 %) eyes had CME. CONCLUSIONS Most common cause of CME was NPDR followed by BRVO, PDR and CRVO. Sensitivity of OCT in comparison with FFA was 100 % with diagnostic accuracy of 81.38 %. Hence, one can use OCT as first modality investigation for diagnosis of CME. KEYWORDS Optical Coherence Tomography, Fundus Fluorescein Angiography, Cystoid Macular Oedema, NPDR
