Purpose: Two cases of eyelids Necrotizing Fasciitis in children were presented. The first one with chicken pox, and\r\nthe second was previously healthy.\r\nDesign: Interventional Report cases.\r\nMethods: Two cases of eyelids Necrotizing Fasciitis in children were studied. The first case was a 7 years old girl\r\nwho presented a necrotizing fasciitis in superior and inferior eyelids with a serious toxic shock as a complication of the\r\nchicken pox. Parenteral antibiotic treatment was not enough to stop the necrotizing process and surgical debriding was\r\nneeded for the gangrenous tissues. In the eyelid culture Streptococcus pyogenes grew. A free skin graft was implanted\r\nto the inferior eyelid. The second case was presented in a 6 months old girl, who developed necrotizing fasciitis of her\r\nlower left eyelid without any trauma antecedent. The ocular and blood cultures did not show any microorganism growth.\r\nAn appropriate antibiotic coverage and management of systemic manifestations leads to a fast recovering; even though\r\nthe developed necrosis demanded surgical debriding and a retroauricular free skin graft was performed later....
Purpose: To compare the presence of cell fragments and entire cell bodies on the retinal side of the internal limiting\r\nmembrane (ILM) after removal with and without dye assistance in traction maculopathies.\r\nMethods: En-bloc removal of the ILM and epimacular tissue was performed during vitrectomy in 75 eyes without\r\ndye-assistance and in 45 eyes with assistance of either Brilliant Blue G (BBG) or Trypan Blue (TB). We included 79\r\neyes with macular holes (MH) and 41 eyes with other traction maculopathies. All ILM specimens were processed by\r\nserial sectioning preparation for light microscopy. Exclusively, if cellular elements of more than 2 �µm in diameter were\r\nfound on the retinal side of the ILM by light microscopy, specimens were prepared for transmission electron microscopy.\r\nResults: 23 (19%) specimens of this series demonstrated such cell fragments and entire cell bodies on the retinal\r\nside of the ILM. Specimens removed from MH eyes demonstrated less frequently retinal cell debris than specimens\r\nremoved from other traction maculopathies. If epiretinal cell proliferation was seen, cellular debris on the ILM was\r\nsignificantly more frequent, irrespective of BBG or TB assistance.\r\nConclusions: Removal of cellular structures on the retinal side of the ILM during ILM peeling appears to be\r\nassociated with epiretinal cell proliferation. The presence of cell fragments and entire cell bodies on the retinal side of\r\nthe ILM seems unrelated to the use of BBG and TB. Epiretinal membranes with wrinkling and folding of the ILM may\r\ncontribute to structural changes that facilitate pulling off parts of cells or entire cell bodies during ILM peeling....
Background: The risk of injury or fatality (driver, passenger or pedestrian) associated with motor vehicle accidents\r\nhas been determined to increase with age, as a result of age-related declines in vision, motor and cognitive functioning.\r\nElderly drivers with age related macular degeneration are particularly vulnerable to sensory visual impairment when\r\ndriving at night, as they suffer declines in both Contrast sensitivity (CS) and Glare recovery (GR).\r\nObjective: This study evaluates the relationship between carotenoid supplementation, CS and GR and the\r\nrelationship between driving ability and retinal macular pigmentation.\r\nMethods: Self-described driving performance is the basis of this report, with data derived from the Zeaxanthin and\r\nVision Function (ZVF) Study (FDA IND #78,973), a 1 year, n=60, 4 visit, prospective randomized controlled clinical trial\r\n(RCT) of predominantly elderly male veterans (74.9 SD 10 y) with mild / moderate Age related Macular Degeneration\r\n(AMD). The twenty five question - National Eye Institute Visual Functioning Questionnaire (VFQ-25) v. January 2000,\r\nRand Corporation�® includes 3 questions assessing driving performance and were completed at baseline and 1 year\r\nafter nutritional supplementation with approximately equal daily doses of the retinal macular carotenoids: lutein (9 mg)\r\nor zeaxanthin (8 mg). Replicate measures of foveal 1 degree estimated retinal macular pigment optical density were\r\nevaluated with the QuantifEye�® (ZeaVision, Chesterfield, MO) heterochromic flicker photometer.\r\nResults: VFQ25 self-described driving ability was notably associated with baseline pre-supplementation macular\r\npigmentation. Linear regression modeling suggests that self-described ability to safely drive a car was strongly\r\nassociated with final macular re-pigmentation post supplementation (P=0.02). Moreover, the greatest effect was found\r\nwith zeaxanthin (ns but P = 0.057 for trend) even though lutein had greater effects than zeaxanthin with respect to CS\r\nand GR, suggesting that unique zeaxanthin post-receptorial processes may be at play.\r\nDiscussion: Carotenoid supplementation and subsequent macular repigmentation improved the self-described\r\ndriving ability of patients with macular degeneration. Older male drivers with AMD should be encouraged to have\r\ntheir foveal macular MP measured at yearly eye examinations. If low macular pigment is found, these patients should\r\nattempt macular re-pigmentation via diet and/or supplementation to improve the sensory aspect of driving....
Background: To report a case of mirror unilateral lacrimal fistula in monozygotic twins and to review the literature.\r\nMaterials and Methods: Full ophthalmic examination including pupillary light reflex, Hirschberg test, ocular\r\nmovements, face photographs was performed. Pediatrics consultation was requested.\r\nResults: We report an identical twins, 6-months age - boys, with unilateral lacrimal fistula. For each twin, there\r\nwas lacrimal fistula, located on the right for the first twin and on the left for the second one. The parents noted that the\r\npits were present since birth. It was asymptomatic in each twin from the outside. There were no ocular and systemic\r\nassociations with fistula.\r\nConclusion: We report first case to our knowledge of mirror unilateral lacrimal fistula in monozygotic twins....
Background: The majority of complications of Laser in Situ Keratomileusis leading to vision loss are related\r\nto the corneal flap. Uses of the femtosecond laser for flap construction has been shown have improved safety and\r\npredictability when compared to mechanical keratome use. We report a case of irregular astigmatism following second\r\npass with a femtosecond laser performed due to incomplete flap construction.\r\nMethods: Single observational case report.\r\nResults: Examination revealed a horizontal linear opacified stromal scar likely representing a discontinuity of the\r\ndeeper second flap plane with transection into the original flap plane. This complication caused a loss of six lines of\r\nbest corrected visual acuity.\r\nConclusion: This case demonstrates that complications resulting in persistent significant visual loss are possible\r\nwith use of the femtosecond laser for a second pass following incomplete flap construction....
We report two unusual cases of wound dehiscence associated with graft loss following Deep Anterior Lamellar\r\nKeratoplasty (DALK). The first case was a 41-year-old man who had DALK for keratoconus, resulting in visual recovery.\r\nThe patient returned 14 months later, after being struck with a fist on his left eye, resulting in complete loss of the graft\r\nand a tear in the Descemet�s Membrane (DM). Grafting with a preserved cornea resulted in gradually recovery in\r\nboth graft clarity and visual acuity. The second case was a 46-year-old man who had undergone uneventful DALK for\r\nkeratoconus. Running suture removal was performed at 21 months postoperatively. When he returned 6 days later, the\r\ngraft was lost and intact DM exposed. Securing a preserved corneal graft over the DM resulted in gradual recovery.\r\nThese results indicate that wound dehiscence associated with complete graft loss can occur following uneventful\r\nDALK. Presence of a recipient DM may act as a physical barrier to other ocular tissues....
