본 연구는 2016년 6월 16일부터 2016년 12월 31일까지 건강검진센터를 방문한 726명을 대상으로 Schirmer's 검사와 대사증후군 검사를 통해 전신적 만성 염증성 상태가 국소적 만성 염증성 상태로서의 안구건조증에 미치는 영향을 알아보고자 시행하였다. 대상자중 hs-CRP, HbA1c를 동시 측정한 214명을 대상으로 연구를 진행하였다. 연구대상자 중 고 연령일수록 (p<0.001), 성별로는 여성에서 유의하게 안구건조증이 증가하였으며(p=0.020), 공복혈당과 hs-CRP와는 연관이 없었다. 또한 HbA1c가 증가할수록 안구건조증에 대한 위험도가 증가하였다(β=1.960, p=0.025). 따라서 안구건조증은 만성 염증성 상태로 인한 눈물샘의 미세혈관 변화에 의한 것이 아니며 당뇨환자의 경우 단기간의 혈당 조절보다 장기간의 혈당 조절상태가 더욱 중요하게 작용할 수 있음을 알 수 있으며 당뇨병 환자에서 안구 건조증의 높은 유병률은 만성 염증으로 인한 미세 혈관 변화보다는 자율 기능 장애로 인한 것으로 생각된다.

Sj$\ddot{o}$gren's syndrome (SS) is an immunologic disorder characterized by progressive destruction of the exocrine glands due to infiltration of lymphocyte resulting in mucosal and conjunctival dryness accompanied by a variety of autoimmune phenomena. And SS is divided into primary and secondary by accompanying collagen vascular diseases. In Korea, only a few cases of primary SS and primary SS with interstitial pneumonitis have been documented. Recently we experinced a suspected case of primary SS with interstitial pneumonitis diagnosed by sublabial and open lung biopsy, Schirmer's test and slit lamp test.

Objectives : The aim of this study is to review the trend of clinical trials conducted with the intradermal acupuncture treatment on dry eye syndrome. Methods : Through 4 foreign online databases(PubMed, Cochrane Library, EMBASE, and CNKI) and 3 domestic online databases(NDSL, RISS, and OASIS), we searched for clinical studies performed acupuncture treatment for dry eye syndrome from 2000 to 2020. Only randomized controlled trials(RCT) were selected and analyzed with the research method. Results : A total of 4 studies were reviewed. Cuanzu(攢竹, BL2), Taiyang(太陽, EX-HN5), and Sibai(四白, ST2) were the most frequently used acupoints in the studies. Among the evaluation indexes, Schirmer I test(SIT), tear film break-up time(BUT) were the most frequently used outcomes. In the most of the 4 studies, intradermal acupuncture treatment showed significant therapeutic effects for dry eye syndrome. Conclusions : These results suggest that it is necessary to develop more detailed standards for intradermal acupuncture treatment method as the method of intradermal acupuncture is getting more diverse, and objective tools are needed to evaluating dry eye syndrome.

The effects of cryosurgery on tear production and histological changes of the third eyelid were studied in dogs. Clinically normal 12 mixed breeds weighing 2∼6 kg were divided into three groups and treated as follows; 45 seconds double freeze-thaw treated group, 60 seconds double freeze-thaw treated group and 90 seconds double freeze-thaw treated group. The significant decrease of the tear production after cryosurgery was shown in all groups throughout the observed periods(p<0.05). However, there was no difference among groups. The main complications after cryosurgery were chemosis and conjunctival injection. Other complications such as eyelid edema, eyelid depigmentation and keratitis were more preominent in group III compared to those of groups I and II. On histopathological examination, chronic inflammatory changes and regeneration of the third eyelid glands were noted in group I and predominated loss of the third eyelid glands and necrosis of hyaline cartilage were observed in group III However, such changes were less appeared in group II. The results of this study suggested that double freeze-thaw cryosurgery for 60 seconds on the third eyelid glands would be the most effective method for treating tear staining syndrome.

A 4-year-old female Shih-tzu with severe episcleral congestion and buphthalmos in left eye was referred to the Veterinary Teaching Hospital, Chonnam National University in October 1998. During two months in local veterinary clinics, the dog had been treated unsuccessfully with tarsorrhaphy and antibiotics. By history taking, cause of the glaucoma was ascertained as accidental nonpenetrated cornea trauma by owner, Ophthalmic examination revealed that the left eye was buphthalmic with severe episcleral congestion, pain and fever. The direct pupillary light response could not be evaluated in the left eye, but right eye had normal reaction. The intraocular pressure was 4.5 mmHg in the right eye and 33 mmHg in the left eye, as measured with a Schiotz tonometer, Ultrasonographic finding revealed hyperechoic vitrous body and central echofree material. The Schirmer tear test showed 20 mm in the left eye and 8 mm in the right eye. The hematologic examination revealed monocytosis. The initial medical treatment was admitted, but there was no response. Transpalpebral enucleation in the left eye under inhalation anesthesia with enflurane 1.2 vol% in oxygen was performed. The day after operation the left eye ravealed no exudate, and pain, and the systemic vital signs were normal. The prognosis is excellent.

Background: Dry eye disease (DED) cannot be diagnosed by a single test because it is a multifactorial disorder of the ocular surface. Although studies on various dry eye tests (DETs) in dogs have been reported, standard criteria have not been established except for the Schirmer tear test 1 (STT-1). Objectives: To establish reference values for DETs in dogs with normal STT-1 values (≥ 15 mm/min) and to analyze the correlation between DETs. Methods: The STT-1 was performed in 10 healthy Beagle dogs (20 eyes). After 20 min, interferometry (IF) for estimating the lipid layer thickness (LLT) of the tear film, tear meniscus height (TMH), non-invasive tear breakup time (NIBUT), and meibomian gland loss rate of the upper eyelid (MGLRU) and lower eyelid (MGLRL), were measured using an ocular surface analyzer. Results: Mean values for STT-1, TMH, and NIBUT were as follows: 21.7 ± 3.4 mm/min, 0.41 ± 0.21 mm, and 19.1 ± 9.5 sec, respectively. The most frequent LLT range, measured by IF, was 30-80 nm (11 eyes), followed by 80 nm (5 eyes) and 80-140 nm (4 eyes). MGLRU ≤ 25% was measured in 11 eyes and 26%-50% in 9 eyes; MGLRL ≤ 25% in 8 eyes and 26%-50% in 12 eyes. Besides positive correlation between TMH and NIBUT (P = 0.038), there were no significant associations between DETs. Conclusions: Data obtained in this study provided normative references that could be useful for diagnosing DED and for further research into correlation between DETs in dogs with DED.

Impression cytology는 결막상피의 표층을 떼어내기 위해 안구 표면에 cellulose acetate filter 재질을 같이 이용한다. 이 방법은 비 침습적이고 쉽게 시행할 수 있으며 환자에게 최소한의 불편감을 주며 결막표면에 반복해서 시행하여 변화를 관찰하기 위해 사용될 수 있다. 이 방법으로 결막 표면의 형태학적 연구와 squmaous metaplasia의 정도를 평가할 수 있다. 본 연구는 건성안 환자에서 impression cytology를 이용하여 결막표면을 평가하기 위해 수행되었다. 70명의 콘택트렌즈 비착용 학생을 대상으로 조사하였는데 먼저 조사 대상자들에게 McMonnies dry eye symptom questionnaire을 작성하도록 하였다. 그리고 비침습성 tear thinning time(TTT) 검사를 시행하고 다음에 침습성 검사인 Schirmer tear test(SIT), tear film break-up time(TBUT) tests 그리고 Rose-bengal staining올 시행하여 건성안 의심자를 분류하였다. 하 안구결막으로부터 결막 상피세포는 impression cytology기법으로 수집하여 PAS(Periodic Acid Schift)-haematoxylin 염색을 시행하였다. 배상세포와 결막상피세포는 광학현미경 400배에서 관찰하여 squamous metaplasia의 정도에 근거한 Nelson Grading scale에 따라 분류하였는데 이는 배상세포 밀도, 세포의 크기와 형태, 핵:세포질 비 등을 포함한다. 건성안 의심자는 상피세포의 형태적 변화, 핵의 변화, 배상세포 밀도 감소를 보였다. 세포학적 변화 정도는 건성안 조건의 정도에 관련이 있었다. 상피세포 형태를 Nelson의 분류시스템으로 단계를 나눈 결과 대조군의 91.43%가 grade 0 이었고 8.57%가 약간의 이상형태인 grade 1이었다. 반면에 건성안 의심자에서는 20%가 grade 0, 42.86%가 grade 1, 34.29%가 grade 2 그리고 2.86%가 심한 형태적 변화를 보인 grade 3를 나타냈다. Impression cytology는 부작용이나 거부반응이 없는 안구 표면 상피의 비 침습적 또는 최소 침습적 생검법으로 생각되며 안구표면을 포함하는 광범위한 과정을 위한 유용한 진단 기법으로 안전하고 간단하며 건성안 의심자의 다양한 안구 표면 변화의 이해를 증진시키는데 도움을 줄 수 있을 것으로 사료된다.

An 1-year-old, spayed, female Labrador Retriever was presented for bilateral epiphora. A complete ophthalmic examination was conducted, including Schirmer tear test, rebound tonometry, fluorescein staining, slit lamp biomicroscopy, and binocular indirect ophthalmoscopy. To determine the patency of the nasolacrimal duct system, a nasolacrimal flush and dacryocystorhinography were also performed. Although the nasolacrimal flush showed patency in the upper and lower lacrimal puncta in both eyes (OU), the lower lacrimal puncta were not found in the original palpebral conjunctiva, but on medial canthal skin with very small opening. Moreover, the nasolacrimal ducts in OU were not patent with flushing. Bilateral nasolacrimal duct atresia was confirmed by dacryocystorhinography. No other abnormalities of the eyes were found on complete ophthalmic examinations. Bilateral congenital anomalies of the lower lacrimal puncta and nasolacrimal duct atresia were diagnosed in this dog.

This study was performed to identify the effect of synovium graft on conjunctiva in rabbits after dry eye induction. Six New Zealand White rabbits were used as dry eye models. Both eyes were divided to two groups as control and synovium graft group. The synovium graft was performed in fourth week after dry eye modeling. Quantitative change of tears through Schirmer tear test (STT), qualitative change of tear film through tear film break up time (TFBUT), and damage of cornea through fluorescein staining were observed for 10 weeks at intervals of two weeks. Histological examination was performed to evaluate cornea and conjunctiva at tenth week. In both groups, STT and TFBUT were significantly decreased in 4 weeks after modeling compared to 0 weeks (p < 0.05) . After synovium graft, there were increases in STT value at 4 weeks and TFBUT at 4 and 6 weeks in graft group (p < 0.05). Corneal fluorescein staining showed no significant difference between the two groups. In histopathological examination, grafted synovium was detected as round to ovoid ingression folds, well attached to grafted regions with 0.11 ± 0.04 mm² (range, 0.05-0.16 mm²). These results indicated that the synovium graft on the conjunctiva had an effect on the qualitative and quantitative improvement of the tear film even though there was no histological change.
