Night vision in a case of vitamin A deficiency due to malabsorption.

Abstract

(normal 5-45 ,ug/ml (5-45 mg/i)), total protein 6-3 g/dl (63 g/l) (normal 6-5-8-5 g/dl (65-85 g/l)), albumin 3X7 g/dl (37 g/l) (normal 3-2-5-0 g/dl (32-50 g/l)), globulin 2-6 g/dl (26 g/l) (normal 2-5-4-5 g/dl (25-45 g/l)), uric acid 7-0 mg/dl (1P2 mmol/l) (normal 3-0-7 5 mg/dl (0-5-1P2 mmol/l)), creatinine 1-2 mg/dl (106 ,umol/l) (normal 0-7-15

Functional observations in vitamin A deficiency: diagnosis and time course of recovery

“…[1][2][3][4] Night blindness is usually the first clinical presentation of VAD, which may result from poor dietary intake, decreased intestinal absorption (eg following surgical intervention for Crohn disease or morbid obesity), defective transportation, or liver disease. [5][6][7][8][9] The fundi of chronic VAD patients may display multiple white or grey-white spots scattered in the peripheral retina, which resolve with supplementation. 10 However, the majority of published VAD cases have normal ocular examinations.…”

Conjunctival necrosis and bleb leakage secondary to an adherent conjunctival foreign body

“…4 Rare cases of aggressive astrocytic hamartoma leading to retinal exudation and even exudative retinal detachment have been reported. 5 In summary, this patient developed a sporadic retinal astrocytic hamartoma with retinal exudation, in the …”

“…Surgical techniques are conjunctival suturing, resuturing of trabeculectomy flap, bleb revision with autologous or donor scleral grafting, bleb excision, conjunctival advancement, lyodura, and tenons patching. 5 Surgical bleb revision has a high success rate with regard to maintaining a functioning bleb and to preserving vision. When compared with nonincisional treatment, patients with late bleb leaks managed with conjunctival advancement are more likely to have successful outcomes.…”

Reversible night blindness in a patient with neuroendocrine tumour of pancreas

“…[4][5][6][7] However, night blindness due to vitamin A deficiency in relation to pancreatic neoplasm is probably rare and to our knowledge there are only a couple of case reports in medical literature. 2,8 Vitamin A (retinol) is ingested mainly as retinyl esters and a range of carotenoids, the most abundant of which b carotene is cleaved in the enterocyte to retinaldehyde and then reduced to retinol.…”

“…This differential susceptibility to vitamin A deficiency is well documented in previous reports. 5,6 If night blindness occurs in a patient with a pancreatic neoplasm one should suspect vitamin A deficiency. Another possibility is CAR although there are no reports suggesting its association with pancreatic malignancy and also the electrophysiological findings in CAR are different from vitamin A deficiency-related night blindness.…”
