Even though the diagnosis depends on clinical examination, in cases with branch retinal vein occlusion (BRVO), fundus fluorescein angiography (FFA), optical coherence tomography (OCT), and optical coherence tomography angiography (OCTA) provide unique data for follow-up, management and prognosis. In FFA, delay of laminar flow phase in the involved branch, hyperfluorescence due to leakage from the vessel wall in the late phases, hypofluorescence due to the blockage by hemorrhage, and soft exudates, and hyperfluorescence due to macular edema can be detected. In OCT, macular thickening, cystic spaces, serous retinal detachment, hyperreflective dots, disorganization of the outer retinal layers – particularly the photoreceptor inner and outer segments line and the external limiting membrane – can be seen. OCTA reveals non-perfusion, particularly in the deep capillary plexus.

Abstract Purpose To study the macular features in Eales disease patients observed with fundus fluorescein angiography (FA), optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA). Methods A cross-sectional study was done on treatment naïve 31 eyes (23 patients) with Eales disease. Baseline parameters such as Best-corrected visual acuity (BCVA), slit-lamp bio microscopy (SLB), indirect ophthalmoscopy, FA, spectral-domain OCT {quantitative (central macular thickness [CMT]) and qualitative analysis on SD-OCT} and OCTA were performed. Any media opacity precluding the above investigations was excluded. Results Macular findings comprised of- epiretinal membrane, macular exudation, full thickness macular hole, sub internal limiting membrane bleed, cystoid macular oedema, neurosensory detachment and retinal thickening. Sixteen (51.6%) of our patients had macular changes as seen on all modalities together. SLB and indirect ophthalmoscopy missed macular findings in 50% patients and FA in 18.8% patients. OCT and OCTA diagnosed all macular findings. On comparison of mean BCVA in patients with macular involvement on FA, OCT and OCTA, compared to those without macular involvement, patients with macular involvement had lower BCVA (p 0.000, 0.01 and 0.001 respectively). Thus, FA missed many patients who had significant macular involvement and hence less vision. Conclusion Eales disease though described in literature as classically being peripheral retina disease process, also has macular involvement. OCT and OCTA are useful guides to evaluation of macular involvement in these patients. The latter seems to be superior to FA in detecting macular abnormalities in this ailment. OCTA is non-invasive and shows deep capillary plexus changes which are not shown by any other modality.

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
