Abstract
Summary
Macular thickening caused by fluid leaking and buildup in the macula’s intracellular compartments is known as cystoid macular edema (CME). Cystoid macular edema (CME) is a prevalent ophthalmic illness caused by a wide range of different eye and systemic issues. At least 21 million individuals worldwide develop CME annually because of diabetes, and another 3 million get it as a result of retinal vein occlusion. About 40% of people with uveitis lose their vision due to this. Reduced visual acuity and visual distortion are two of the signs. Dye leaks by blood vessels in the parafovea leaking into holes on the outer retina called cystoids characteristic angiographic pattern of CME known as a ”petaloid” look during angiogram. When ophthalmology fails to detect Conventional Medical Examination, Fundus Photograph Optical coherence tomography (OCT) and fluorescence angiography (FA) may be very useful in the diagnosis of vascular disease them individuals.
Mild pigmentary changes may make it difficult to identify people whose Individuals whose vision loss from CME has improved but not completely. To objectively image the retina in high resolution cross sections, optical coherence tomography (OCT) has recently gained popularity. This makes it possible for very accurate evaluations of retinal thickness in instances of diabetic retinopathy. The regular interactions of the retinal environment might be disrupted by a number of risk factors. The vasculature is characterized by a dynamic equilibrium between osmotic pressure, hydrostatic pressure, capillary permeability, and tissue compliance. Objectives visual acuity and optical coherence tomography were used to evaluate cystoid macular edema in this research.
Thirty patients with cystoid macular edema of varying degrees of diabetes and non-diabetic controls participated in this cross-sectional observational research. All patients had a full medical and ophthalmic history taken, had their eyes examined using a standard slit lamp to look at the cornea, iris, lens, and anterior chamber, had their best-corrected vision measured, and had their retinas and optic nerves looked at using a fundus bio microscopy with a +90 lens.
Summary of our results:
• In terms of the sex distribution of the eyes examined, 18 (60 percent) belonged to men and 12 (40 percent) to girls.
• Median (interquartile range) age was 58.50 (55.0 - 64.0) and the interquartile range (IQR) was 58.80 (62.0 - 70.0).
• In terms of which side of the eye was afflicted, 16 (53.3% of all cases) were on the right and 14 (46.7% of all cases) were on the left.
• The range of macular thickness was from 298.0 to 512.0 m, with a mean SD of 419.3 51.67 m and a median (interquartile range) of 426.5 (377.0 - 446.0).
• The range of Log Mar scores for visual acuity was 0.50-1.30, with 0.93-0.22-LogMar being the mean and standard deviation, and 1.0 (0.80-1.0) being the median and interquartile range.
• Snellen One patient (3.5% of the total) was found to have visual acuity of 6/18, four patients (13.3%) were found to have visual acuity of 6/24, six patients (20%) were found to have visual acuity of 6/36, fourteen patients (46.7% of the total) were found to have visual acuity of 6/60, two patients (6.7% of the total) were found to have visual acuity of 6/100, and three patients (3.3%) had (10 percent).
• A high correlation between macular thickness and visual acuity was found (r = 0.953, P 0.001).
