Based on the severity of ocular surface damage, NK is classified into 3 stages. Stage 1 NK is characterized by superficial punctate keratopathy, tear film instability, and reduced corneal sensation. The therapeutic efficacy of PRGF eye drops for NK stages 2 and 3 has been previously reported. In this study, we evaluated the efficacy and safety of autologous PRGF eye drops in improving corneal sensitivity and other ocular surface clinical signs in patients with stage 1 NK.<\/p>\n<p><strong class=\"sub-title\">Methods:\u00a0<\/strong>Retrospective chart review.<\/p>\n<p><strong class=\"sub-title\">Results:\u00a0<\/strong>26 eyes of 15 stage 1 NK patients (seven males, eight females), aged 76.3 \u00b1 12.1 years, were included in the study. The mean treatment duration was 2 \u00b1 1.8 months. With PRGF treatment, corneal sensitivity increased from 2.8 to 4.5 cm in 53.8% (14\/26) (p &lt; 0.01), TBUT increased from 3.6 to 5.0 s in 69.2% (18\/26) (p &lt; 0.01), and Schirmer score increased from 13.7 to 16.8 mm in 80.7% (21\/26) of treated eyes (p &lt; 0.01). Similarly, an improvement in corneal staining (punctate epithelial erosions) and MMP-9 levels was seen in 80.7% (n = 21) and 65.4% (n = 17) of treated eyes, respectively. BCVA improvement was seen in 26.9% of treated eyes (n = 7).<\/p>\n<p><strong class=\"sub-title\">Conclusions:\u00a0<\/strong>This study demonstrates the effective role of PRGF therapy in recovering corneal sensation and tear film function and in the healing of corneal erosions in stage 1 NK patients.<\/p>\n<\/div>\n<p><strong class=\"sub-title\">Keywords:\u00a0<\/strong>Neurotrophic keratitis; Ocular surface disease; Plasma rich in growth factors.<\/p>\n<\/div>\n<p>[\/vc_column_text][vc_empty_space][vc_column_text]<\/p>\n<h3>Figures<\/h3>\n<p>[\/vc_column_text][vc_empty_space][\/vc_column][\/vc_row][vc_row content_text_aligment=&#8221;center&#8221;][vc_column]<div class=\"qodef-image-gallery qodef-grid-list qodef-disable-bottom-space  qodef-ig-grid-type qodef-four-columns qodef-tiny-space  qodef-image-behavior-lightbox\">\n\t<div class=\"qodef-ig-inner qodef-outer-space\">\n\t\t\t\t\t<div class=\"qodef-ig-image qodef-item-space\">\n\t\t\t\t<div class=\"qodef-ig-image-inner\">\n\t\t\t\t\t\t\t\t\t\t\t<a itemprop=\"image\" class=\"qodef-ig-lightbox\" href=\"https:\/\/www.btitrainingcenter.com\/wp-content\/uploads\/2021\/08\/nihpp-rs3040369v1-f0001.jpg\" data-rel=\"prettyPhoto[image_gallery_pretty_photo-741]\" title=\"&lt;strong&gt;Figure 1.&lt;\/strong&gt; Changes in corneal sensitivity and tear film parameters after treatment with PRGF eye drops.\">\n\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.btitrainingcenter.com\/wp-content\/uploads\/2021\/08\/nihpp-rs3040369v1-f0001-200x200.jpg\" alt=\"\" width=\"200\" height=\"200\" \/>\t\t\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t\t<div class=\"qodef-ig-image qodef-item-space\">\n\t\t\t\t<div class=\"qodef-ig-image-inner\">\n\t\t\t\t\t\t\t\t\t\t\t<a itemprop=\"image\" class=\"qodef-ig-lightbox\" href=\"https:\/\/www.btitrainingcenter.com\/wp-content\/uploads\/2021\/08\/nihpp-rs3040369v1-f0002.jpg\" data-rel=\"prettyPhoto[image_gallery_pretty_photo-741]\" title=\"&lt;strong&gt;Figure 2 and Figure 3.&lt;\/strong&gt; Represent the initial and final status of two cases with stage 1 NK after 8.3 and 8.5 weeks of treatment with PRGF eye drops. a: basal status, b: final status of patient after PRGF treatment.\">\n\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.btitrainingcenter.com\/wp-content\/uploads\/2021\/08\/nihpp-rs3040369v1-f0002-200x200.jpg\" alt=\"\" width=\"200\" height=\"200\" \/>\t\t\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t<\/div>\n<\/div>[vc_empty_space height=&#8221;50px&#8221;][\/vc_column][\/vc_row][vc_row][vc_column]<a itemprop=\"url\" href=\"https:\/\/www.btitrainingcenter.com\/wp-content\/uploads\/2021\/08\/41.-nihpp-rs3040369v1.pdf\" target=\"_blank\"  class=\"qodef-btn qodef-btn-medium qodef-btn-solid btnWebRosa2\"  >\n    <span class=\"qodef-btn-text\">Descarregar artigo<\/span>\n    <\/a>[\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p><strong>Res Sq [Preprint]. 2023 Jun 30:rs.3.rs-3040369.<\/strong><br \/>\nNeurotrophic keratitis (NK) is a neurodegenerative disease that can lead to corneal hypoesthesia, decreased tear production, and epitheliopathy.
