This decision was based on the criteria for sight impairment to include BCVA of 6/24 with moderate contraction of visual field, media opacities or aphakia.
The exclusion criteria were unreliable GVF testing, poor central fixation due to central visual loss and media opacity precluding adequate imaging.
The patients were chosen for treatment if they had reduced visual acuity with capsule opacity, glare or monocular diplopia.
5. Cataract blind people (central lens opacity and visual acuity of 6/60 or less) are offered counselling by female community health volunteers.
However, over a two-year period the important secondary outcome measures of change in visual acuity and corneal opacity showed no significant difference.
Disorders in any of these layers can cause corneal opacity and visual disturbance: epithelial disorder (e.g., limbal stem cell deficiency), stromal disorder (e.g., corneal dystrophy), and endothelial disorder (e.g., bullous keratopathy).
In our study, the patients with dry eye syndrome started therapy with AS eye drops because the symptom had not resolved with conventional therapy and they had a long history of chronic inflammation and recurrent epithelial defects leading to infection, opacity, and visual capacity damage [ 56].
OCT has evolved to enable detailed imaging of many intraocular structures [ 7], however this case report describes the first use of OCT as a means of objectively and qualitatively assessing the visual impact of vitreous opacities.
In our study, we limited the variables that could contribute to measurement artifacts including cataracts or other media opacities, poor visual acuity, and pupillary miosis, but the loss of fixation of the patient cannot be quantified with our technology.
Common to these eye pathologies, such as the loss of the visual field, are the cornea opacity resulting in a blurred vision and the yellowing of the cornea that alters color perception.
