Anterior segment examination revealed bilateral posterior subcapsular cataracts, while dilated fundoscopic examination was unremarkable.

Multifocal ERG demonstrated reduced amplitudes in the central and parafoveal rings, indicating localized retinal dysfunction.

OCTA disclosed bilateral, irregular enlargement of the foveal avascular zone consistent with perifoveal ischemia.

These vascular abnormalities corresponded to the areas of inner retinal thinning with secondary outer nuclear layer expansion in structural OCT.

A 19-year-old man presented with a sudden loss of vision in both eyes 12 days after experiencing initial systemic symptoms suggestive of dengue fever.

Pupillary light reflex was reduced in both eyes.

Dilated fundoscopic examination revealed optic disk swelling and a small deep Henle fiber layer hemorrhage near the fovea in both eyes.

Immunoglobin M was positive for dengue fever.

Fundus examination revealed bilateral blurred margins of the disks and perivascular hard exudates.

Fluorescein angiography demonstrated peripheral capillary nonperfusion areas in both eyes.

It also revealed an aberrant cilioretinal artery in the right eye.

Best-corrected visual acuity remained stable, with no evidence of progression or development of neovascularization after a 5-year follow-up.

Intelligent image-processing systems enable visually impaired individuals to access visual information in unprecedented ways.

Multivariate logistic regression showed that age and visual field defect explained 89% of the variation in efficacy of the device.

Nearly half (45%) of the participants indicated a positive rating with the SUS.

The PGIC rates showed a minimal improvement with a mean score of 4.2 (SD:1.8).

Regression modelling demonstrated a good relation between the questionnaires scores and demographic, disease and visual factors (P < .05).
