Impact of ocular care training of nursing staff on the incidence of ocular surface disorder in medical intensive care unit patients

Purpose: To assess the knowledge of nursing staff on ocular care in medical intensive care unit (ICU) and to compare the incidence of ocular surface disorders in patients of medical ICU pre? and post?training. Methods: Two hundred patients admitted in medical ICU for more than 24 h underwent a detailed ocular examination along with documentation of ICU stay, ventilation status, and Glasgow coma scale (GCS) scoring. An assessment on ocular care knowledge among the nursing staff of medical ICU was done. They were further given training in the form of audio?visuals and demonstration, and an eye care protocol was given to them. The second phase of the study was carried out in the same manner. A comparison was made between pre?training and post?training incidence of ocular surface disorders among ICU patients. Results: Ventilated patients had more eye discharge. Incidence of eye discharge was more in patients with duration of stay of more than 7 days in ICU. Ocular surface disorders closely correlated with the degree of lagophthalmos. There was significant reduction in ocular morbidity following ocular care training of the nursing staff. Conclusion: Eye care is a very important part of nursing care in sedated and ventilated patients in the ICU. Ophthalmic consultations are routinely needed in ICU subjects who are hospitalized for more than 1 week or if the ICU staff suspects any eye problems.

Síndrome de Cogan Reese / Cogan Reese syndrome

RESUMO Estudo realizado para descrever um caso da síndrome de Cogan Reese. Paciente do sexo feminino, 55 anos, com diagnóstico de síndrome de Cogan Reese. Melhor acuidade visual de 0,67 em olho direito e 0,2 em olho esquerdo. Pelo exame biomicroscópico não se detectou anormalidades no olho direito. No olho esquerdo haviam nódulos pigmentados na superfície anterior da íris, irregularidades corneanas e buraco iriano (pseudopolicoria). A pressão intra-ocular era 18 mmHg no olho esquerdo e havia atrofia óptica glaucomatosa no disco óptico. A paciente havia sido submetida à trabeculectomia três anos atrás. Recentemente o tratamento medicamentoso possibilitou o controle relativo da pressão intraocular. Gonioscopia revelou sinéquias anteriores periféricas. A microscopia especular eletrônica mostrou ICE-cells e baixa contagem de células. A cirurgia filtrante para tratamento do glaucoma usualmente tem sucesso quando realizada precocemente, mas ela pode falhar devido à endotelização da fístula pela membrana anormal do endotélio corneano. O tratamento medicamentoso foi efetivo apesar da falha na trabeculectomia.

ABSTRACT Study conducted to report a case of Cogan Reese syndrome. Female patient, 55 years old with diagnosis of Cogan Reese syndrome. Best visual acuity of 0.67 in the right eye and 0.2 in the left eye. By biomicroscopic examination there was no abnormalities in the right eye. In the left eye there were pigmented nodules on the anterior surface of the iris, corneal irregularities and iris hole (pseudopolycoria). The intraocular pressure was 18 mmHg in the left eye and there was glaucomatous optic atrophy of the optic disk. The patient had been subjected to trabeculectomy three years ago. Recently medical treatment allowed the relative control of intraocular pressure. Gonioscopy revealed peripheral anterior synechiae. Corneal specular microscopy showed ICE-cells and low cell count. Glaucoma filtering surgery is usually successful when done early, but it may fail due to endothelialization of the fistula by the abnormal corneal endothelium. Medical treatment was effective despite a fail trabeculectomy.

Retrospective analysis of clinical features and management for drug-induced keratopathy / 中华实验眼科杂志

Background In recent years,incidence of drug-induced keratopathy is increasing highly.Druginduced keratopathy is lack of typical clinical features and offen confused with the primary disease.Therefore,summarizing and concluding the clinicals feature and standard treatments of drug-induced keratopathy are key problem need to be solved urgently for us.Objective This study was to retrospectively analyze the clinical features and therapeutic procedure of drug-induced keratopathy.Methods A retrospective case series analysis method was adopted.The clinical data of 36 eyes (31 patients) with drug-induced keratopathy were collected by Shandong Eye Hospital from 2008 to 2012,including eye disease history,medication history,medication dosage and duration.A series of relevant examinations were performed,including best corrected visual acuity (BCVA) before and 1 month after treatment,Schirmer test Ⅰ (S Ⅰ t),tear film break-up time (BUT),meibomian gland findings,the location of the keratopathy,the characteristics of keratophthy before and after fluorescein staining.The treating were given,including cessating of the original drugs,applying corneal repair promotion and anti-inflammatory drugs as well as the comprehensive treatment for meibomian gland embolization and dry eye,such as the hot packs and massage in the eyes with meibomian gland dysfunction and a tear dot embolization therapy in the eyes with S Ⅰ t ＜ 5 mm and BUT＜5 s.Paired t test and repeated measured one-way analysis of variance in SPSS 17.0 software were used to compare the BCVA,BUT and S Ⅰ t outcomes.The correlation between corneal repair duration and S Ⅰ t results was analyzed by Pearson linear correlation analysis.Results The primary cause of drug-induced keratopathy was irrational use of drugs,including antiviral drugs,antibiotics,hormone,antiallergic,lowering-intraocular pressure drugs,turn for 23 eyes,12 eyes,10 eyes,1 eye and 1 eye,respectively.Improper route of administration included 25 cases of overuse of eye drops and 6 cases of subconjunctival injection.BCVA was 0.69 ± 0.28 1 month after treatment,which was significantly improved in comparison with before treatment (0.32 ± 0.26) (t =11.02,P ＜ 0.01).Clinical manifestations included corneal epithelial diffusive and point-like roughness,corneal epithelial defect and even corneal ulcer for severe cases,corneal edema,Descemet membrane folds and partially visible corneal filiform.Drug-induced keratophthy was mainly located in the central and lower cornea.Comprehensive therapy was effective with the treating duration about 1 week to 8 weeks.A negative correlation was found between the corneal restore duration and S Ⅰ t results (r =-0.835,P＜0.01).Conclusions Corneal changes secondary to topical medications may affect all layers of the cornea.Clinicians should be mindful of drug-induced ocular disorders.The early diagnosis of druginduced keratopahthy depends on the medical history and clinical features.A comprehensive treating based on ocular surface conditions is available.

Staining Characteristics of Granular Deposits of Granular Dystrophy in Six Cases

Penetrating keratoplasty was performed in six eyes of granular corneal dystrophy. Vision was improved from worse than 0.05 to better than 0.4. Mean follow-up period is 14 months (12-18 months). Corneal deposits were stained for H and E. Masson trichrome, Wilder's reticulin and Luxol fast blue but not for PAS, Congo red and Oil red a stain. Electron micorscopic examination showed that polymorphic, electron dense rod-shaped bodies were present in the Bowman's layer and between stromal lamellae and in the interceliular space of corneal epithelium. And, for the first time we found a area looked like a transformation from normal stroma to the granular deposit.
