An one-year-old, female pointer dog with conjunctival hyperemia, corneal opaque and ocular pain in right eye was referred to Veterinary Medical Teaching Hospital, Chungbuk National University. In the ophthalmic examination the worm was observed in anterior chamber, The heart worm antigen test was positive. A modified Knott's test was negative. The values of complete blood count and serum chemistry (TP, BUN, creatinine, AST, ALT, ALP, albumin, globuline) showed normal ranges. Any abnormality was not detected in the heart using a thoracic radiography and cardiac sonography. Therefore, this dog was diagnosed as ocular filariasis. The worm was removed by surgical incision through a limbus of cornea. The closure of limbal incision was sutured in a simple interrupted suture pattern with 6-0 silk and the eye was reinflated with sterile saline solution. Antibiotics and dexamethasone ophthalmic solution were applied to right eye every 24 hours for 7 days. To prevent latent filariasis, ivermectin was also administered on day 14 of operation. The heart worm antigen test on day 60 was negative. The dog was successfully cured.

This study was performed to evaluate the effects of ocular bacteria and tear lactoferrin on the Tear Staining Syndrome(TSS) in poodle dogs. Staphylococcus, Klebsiella, Micrococcus and Pseudomonas were the most Prevalent microorganisms isolated in normal eyes of poodle dogs, whereas the predominant isolates in the poodle dogs with TSS were Micrococcus, Staptococcus and Staphylococcus. There were no significant differences between the normal and tear-stained poodle dogs in the quantity of tear lactoferrin. In vitro hair staining experiment, bacteria isolated from the eyes with TSS and lactoferrin didn't stain hair. The results have shown that either ocular bacteria or tear lactoferrins were not related to the TSS.

The ultimate purpose of eye movement is to maintain clear vision by ensuring that images of observed objects are focused on the fovea in the retina. Accurate evaluation of ocular movements, including nystagmus and saccadic intrusions, provides very useful information for determining the overall function and abnormality of the complex oculomotor system, from the peripheral vestibular system to the cerebrum. Eye movement tests are therefore essential for the accurate diagnosis of patients who complain of dizziness and imbalance. They help to predict lesion locations from the peripheral vestibular system to the central cerebral cortex and play an important role in differentiation from other diseases. The methodology of recording and interpreting ocular movements using video-oculography are described in this review article.

Lymphoma is the most common primary tumor of the orbit, accounting for 55% of all orbital malignancies. When divided into histopathological subtypes, extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) comprises the largest proportion. Clinical manifestations are unspecific, but in patients with slow-growing painless orbital mass, or red conjunctival lesion suggestive of 'salmon patch', ocular adnexa lymphoma (OAL) should be suspected. Although the pathogenetic mechanism of ocular adnexal MALT lymphoma (OAML) is not yet fully understood, the relationship between OAML and Chlamydia psittaci has been hypothesized recently, similar to that between gastric MALT lymphoma and Helicobacter pylori. This suggests a new treatment option for OAML; bacterial eradication therapy with systemic antibiotics. Several other treatment methods for OAML have been introduced, but no treatment guidelines have been established yet. In this article, we summarize the current knowledge on the clinical features, pathogenesis, diagnostic methods, therapeutic strategies, and prognosis of OAML.

With the widespread use of laser in medical and industrial settings, the incidence of laser injury to the ocular continues to grow among workers involved in handling lasers. The aim of this study is to compare ocular damages after irradiation with various laser wavelengths and power density. Ocular of pigmented rats was irradiated with $CO_2$ laser, 1064 nm Nd:YAG laser, and 532 nm diode laser. We observed damage of cornea, lens, and retina using slit lamp microscope and funduscopy. H&E staining of histopathology were applied to study the specimens. The higher exposure ($200mW/cm^2$, 10 sec) with $CO_2$ laser resulted in severe damage at the cornea. For the 1064 nm Nd:YAG laser, the higher exposure than $10mW/cm^2$ (10 sec) resulted in damage at the cornea and lens. Further, with the 532 nm diode laser, retinal lesions were induced when $10mW/cm^2$ (0.25 sec) was delivered to the eye. Theses results suggest that the ocular damages are different from various laser wavelength and power density.

Purpose: Most of the bilateral structures in our body are not perfectly balanced, such that one side is preferred than the other or it has physiological superiority. Eyes also have an imbalance; the eye with sensory and motional superiority compared to the other is called dominant eye. Authors of this study focused on analyzing the correlation between the dominant eye and levator palpebrae superioris muscle. Methods: The subject of this study was 42 patients with no ptosis and with no past history of blepharoplasty. Hand dominance was identified through questionnaire and dominant eye was identified by hole-in-the-card dominance test (Dolman's test) in all patients. The function of levator palpebrae superioris muscle was measured by MLD (marginal limbal distance). During the measuring procedure, frontalis muscle was not inhibited to avoid the eyelid skin hooding. Results: Out of 42 patients, 27 patients (64.3%) were right ocular dominant, 15 patients (35.7%) were left ocular dominant, 36 patients (85.7%) were right hand dominant and 4 patients (9.5%) were left hand dominant. Out of 27 right ocular dominant patients, right MLD was larger than the left in 26 patients (96.3%). It was larger in average of 0.47 mm (p<0.001) in 27 right ocular dominant patients. Also, left MLD was larger than the right in 11 patients (73.3%) out of 15 left ocular dominant patients. It was larger in average of 0.57 mm (p=0.003) in 27 left ocular dominant patients. MLD on the side of the dominant eye was larger in average of 0.50 mm (p<0.001) than the MLD of non-dominant eye side. Right MLD was larger than the left in average of 0.28mm (p=0.010) in right hand dominant patients, and left MLD was larger than the right in average of 1.15 mm (p=0.025) in left hand dominant patients. Conclusion: The function of levator palpebrae muscle differs in right and left, and the difference correlates with the dominant eye. Also, the function of levator palpebrae muscle is stronger in the dominant eye. We were able to present statistical evidence regarding the difference of the function in right and left levator palpebrae muscle. This may be a factor worth consideration in terms of balancing the eyes during the blepharoplasty.
