Four patients had reduced visual acuity.
The patients were chosen for treatment if they had reduced visual acuity with capsule opacity, glare or monocular diplopia.
Five patients had reduced visual acuity before surgery, and all of the patients had improved visual acuity at 3 months follow-up.
The magnitude of edema in that eye had reduced visual acuity to 0.4, but 4 months after focal laser coagulation, acuity was restored to 0.7.
Improvement in visual symptoms was delayed and incomplete in patient 4, and she had reduced visual acuity and metamorphopsia even after 2 months.
A person with low vision is one who has impaired visual function despite treatment of eye disease and/ or correction of refractive error, and has reduced visual acuity in the better eye which is less than 6/18 but better than light perception (LP) or a visual field constriction to less than 10°, but who uses or is potentially able to use vision for the planning and/ or execution of a task [ 1].
Two weeks before admission to the Infectious Diseases Unit, the patient had noticed an ulcer on his left upper eyelid and four days before admission he had begun to experience reduced visual acuity, with associated photophobia and mild headache which had subsequently improved.
In this study performed in a clinical setting, 35% of the patients were considered to be reduced responders to treatment at the end of follow-up, having either reduced visual acuity compared to baseline and/or persistent intraretinal or subretinal fluid or persistent or recurrent choroidal neovascularisation.
They found that eyes with a recipient stromal bed thickness of less than 20 μm had comparable visual acuity with eyes that had undergone PK, whereas those with a recipient thickness of more than 80 μm had significantly reduced visual acuity.
In Hong Kong, about 4.4% of preschool children had either reduced visual acuity or strabismus [ 11].
Patients with FRMD7 mutations also have variably reduced visual acuity and abnormal optokinetic response (3, 10, 11).
