Metamorphopsia, micropsia,
central scotoma, or impaired color vision may also occur.
Another occlusion option includes a novel contact lens with a monocular
central scotoma, dubbed a scotogenic contact lens (see Figure 3), which eliminates central diplopia while maintaining peripheral viewing capabilities.
The commonest ocular symptom among these patients is blurring of vision followed by
central scotoma. The areas of scotoma corresponds to the areas of edema and haemorrhage in the macula32.
Two cases were reported from Spain [18]: (1) 21-year-old female presenting with typical unilateral ON and

He had a
central scotoma in the right eye, with initially preserved peripheral vision that rapidly deteriorated; fundoscopy was highly suggestive of panuveitis, with fine keratic granulomatous precipitates, aqueous cells, flare grade 1, and choroidal and subretinal infiltration in the posterior pole (Figure 2(a)).
Pregnancy-induced hypertension or pre-eclampsia presents with pathological changes in the retina, blurred vision, retinal detachment, and patient complain of

Patients with central serous chorioretinopathy present with diminution of vision, metamorphopsia, relative
central scotoma, micropsia, dyschromatopsia and blurring of vision.
Central visual field characteristics, including fovea and
central scotoma characteristics, were measured with a scanning laser ophthalmoscope (SLO) (model 101, Rodenstock; Munich, Germany).
