“…Other types of visual field loss included inferior and superior quadrantanopia, constricted visual fields, scotomas, and altitudinal defects. Our findings were similar to those reported in the literature [10–15]. Zhang et al [10] found that scotomas and macular sparing could not be localised to occipital lesions but could occur in other locations of the visual pathway: a statement with which we concur.…”

“…The most common type of visual field loss is that of homonymous hemianopia in which there is loss of the same half of the visual field in both eyes and which occurs in approximately two-thirds of those with visual field loss [7–9]. Other types of visual field loss may include inferior and superior quadrantanopia, constricted visual fields, scotomas, and altitudinal defects [10–15]. …”

Aims. To profile site of stroke/cerebrovascular accident, type and extent of field loss, treatment options, and outcome. Methods. Prospective multicentre cohort trial. Standardised referral and investigation protocol of visual parameters. Results. 915 patients were recruited with a mean age of 69 years (SD 14). 479 patients (52%) had visual field loss. 51 patients (10%) had no visual symptoms. Almost half of symptomatic patients (n = 226) complained only of visual field loss: almost half (n = 226) also had reading difficulty, blurred vision, diplopia, and perceptual difficulties. 31% (n = 151) had visual field loss as their only visual impairment: 69% (n = 328) had low vision, eye movement deficits, or visual perceptual difficulties. Occipital and parietal lobe strokes most commonly caused visual field loss. Treatment options included visual search training, visual awareness, typoscopes, substitutive prisms, low vision aids, refraction, and occlusive patches. At followup 15 patients (7.5%) had full recovery, 78 (39%) had improvement, and 104 (52%) had no recovery. Two patients (1%) had further decline of visual field. Patients with visual field loss had lower quality of life scores than stroke patients without visual impairment. Conclusions. Stroke survivors with visual field loss require assessment to accurately define type and extent of loss, diagnose coexistent visual impairments, and offer targeted treatment.

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Homonymous hemianopia often remains undiagnosed in the pediatric population because children tend not to complain of a visual field defect and usually are not referred for formal visual field testing. However, recognition of visual field defects in children with cerebral insults is important because homonymous hemianopia may interfere with learning, reading, rehabilitation therapies, and driving abilities.…”

A AB BS ST TR RA AC CT T O Ob bj je ec ct ti iv ve e: : The purpose of this study was to investigate the probable transneuronal retrograde degeneration (TRD) of the retinal ganglion cells (RGCs) in humans with cerebral infarction. In addition, the correlation between the laterality and severity of the retinal nerve fiber layer (RNFL) damage and other variables (laterality of hemispheric damage and arterial territory of the infarct) were analyzed. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Thirty consecutive patients were included. All of the subjects underwent complete ophthalmic examinations, including optical coherence tomography (OCT) and perimetry after diagnosis, and in the 6 th and 12 th months. The main outcome measures were the changes in the thicknesses of the RNFL, RGCs, and visual field (VF). The average thickness of the total macular RGCs and MD and PSD values analyzed in the perimetry (using the SITA Standard 24-2 Threshold Test) were taken into account. R Re es su ul lt ts s: : The RNFL thicknesses were reduced significantly in all four quadrants in the contralateral eyes, and in the superior, inferior, and temporal quadrants in the ipsilateral eyes at 12 months. However, the reduction of the RGCs' average total thickness was not statistically significant for either the ipsilateral or contralateral groups (p>0.05). The loss of the VF considering the mean MD measurements was statistically significant in the contralateral group (p=0.001) unlike in the ipsilateral group. C Co on nc cl lu us si io on ns s: : The RNFL thickness was reduced in both eyes at 12 months, providing evidence for TRD. The TRD was more pronounced in the nasal quadrant of the contralateral and temporal quadrant of the ipsilateral eye.K Ke ey y W Wo or rd ds s: : Brain infarction; retrograde degeneration; optic nerve; retinal ganglion cells; visual field tests Ö ÖZ ZE ET T A Am ma aç ç: : Çalışmanın amacı serebral infarkt hastalarında retinal ganglion hücrelerinin (RGH) olası transnöronal retrograde dejenerasyonunu (TRD) araştırmaktır. Retinal sinir lifi (RNFL) hasarının ciddiyeti ve tarafı ile diğer değişkenlerin arasındaki ilişkinin yanı sıra hemisferik hasarın tarafı ve infarkta sebep olan arter bölgesi de analiz edildi. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Otuz ardışık hasta çalışmaya dahil edildi. Tüm hastalar tanı aldıktan sonra optik koherens tomografi (OKT) ve perimetriyi de içeren tam bir oftalmik muayeneden geçirildi ve tetkikler 6. ve 12. aylarda tekrarlandı. Çalışmanın ana amacı RSLT ve RGH tabakalarındaki kalınlık değişimleri ile görme alanındaki değişimleri değerlendirmekti. Ortalama total maküler RGH kalınlığı ve perimetri (SITA-Standart 24-2 eşik test) MD, PSD değerleri dikkate alındı. B Bu ul lg gu ul la ar r: : On ikinci ayda RSLT; kontralateral gözde dört kadranda; ipsilateral gözde ise superior, inferior ve temporal kadranlarda anlamlı derecede incelmiş idi. Ortalama total maküler RGH tabakasındaki incelme ipsilateral ve kontralateral göz için istatistiksel olarak anlamlı değil...
