This study was performed to investigate the ophthalmic findings of the Korean traditional 'Sapsaree' dogs, and to provide ophthalmic references. Five hundred forty-seven Sapsaree dogs were randomly chosen without any criteria preference. Ophthalmic examination was performed bilaterally using ocular equipments, including slit-lamp biomicroscope, tonometer, direct and indirect ophthalmoscope. The obtained data for ophthalmic findings were analysis by the multivariate linear regression model to identify effects of sex, age and hair coat type. For congenital conditions, the incidence of persistent pupillary membrane (PPM) was the most common defect and there was present 8.8 % whereas for acquired ophthalmic diseases, cataract was the most commonly observed (3.7 %) in Sapsaree dog. Other frequent ocular finding included persistent hyaloid vessel remnant (PHVR, 6.2 %) in congenital conditions, and postinflammatory retinal degeneration (PIRD, 3.1 %) and corneal dystrophy (2.4 %) in acquired ophthalmic diseases. Only one significant effect was age of the Sapsaree for PIRD (P=0.040). There are no any significant effect for sex and hair coat types. This study will provide useful guidelines to clinicians and breeders for the basic ophthalmic information on this breed.

Purpose: The effect of two different levels of illumination and the effect of three letter chart types on subjective refraction findings were investigated. Methods: This study involved thirty Malay university students aged between 19 to 23 years old (7 males, 23 females), with their spherical refractive error ranged between plano to -7.75D astigmatism ranged from plano to -1.75D, anisometropia less than 1D and with no history of ocular injury and pathology. Monocular subjective refraction was measured under two levels of illumination (with and without room light) and with three different letter charts (Snellen letter chart, wall mounted letter chart and projected letter chart). Subjective refraction finding was calculated in spherical equivalent in unit diopter (D). Results: There was no significant effect in the subjective refraction findings with Snellen letter chart (t-test=0.15, p-value=0.88), projected letter chart (t-test=-0.19, p-value=0.85) as well as wall mounted letter chart (t-test=0.12, p-value=0.94). One Way ANOVA also revealed when the subjective refractive measures were compared under two different level of room illumination (with and without room light), no significant effect of letter chart types on subjective refraction readings with room light ($F_{2.185}$=0.11, p-value=0.89) and without room light ($F_{2.185}$=0.02, p-value=0.98). Conclusions: Subjective refraction findings were not affected whether the room light was on or off. They were also not affected by the types of letter chart used.

Objectives: HMCO5 is an extract obtained from 8 different herbal mixtures. We undertook a safety evaluation of HMCO5 for a dose range finding (DRF) toxicity test in specific pathogen free (SPF) Sprague-Dawley (SD) male and female rats. Methods: The male and female rats were divided into 4 groups, respectively; G(0), treated with distilled water: G(1), treated with 222 mg/kg HMC05: G(2), treated with 667 mg/kg HMC05, and G(3), treated with 2,000 mg/kg HMC05; HMC05 was administered orally for 4 weeks. The safety evaluation examined clinical signs, mortality, body weight, food consumption, water consumption, ophthalmic findings, urinalysis, hematological values, absolute & relative organ weights, and necropsy findings during the tests. Results: There were no changes in clinical signs, mortality, body weight, food consumption, water consumption, and ophthalmic findings examined during the test periods. In serum biochemical values, triglyceride was increased in male group G(3) and Na$^+$ decreased significantly in male groups G(2), G(3) and G(4). In male group G(4), spleen weight decreased relatively and increases of absolute & relative left ovary weights were found. In addition, an adhesion of liver to diaphragm was found in male group G(2). However, we could not find any dose-interrelationships in these changes. Conclusions: These results indicate that HMC05 extract did not show any toxicity in the DRF toxicity study. Therefore, it suggests that establishment of 1,000, 333 and 111 mg/kg dosages are moderate in a repeated dose 26-week oral toxicity study of HMC05.

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.

Progressive hemifacial atrophy, also known as Parry-Romberg syndrome, is an uncommon degenerative condition which is poorly defined. It is characterized by a slow and progressive atrophy affecting one side of the face. The onset usually occurs during the first two decades of life. Characteristically, the atrophy progresses slowly for several years, and then it becomes stable. Ophthalmic involvement is common, with progressive enophthalmos which is a frequent finding. Cutaneous pigmentation is common in such conditions, however its extension to the conjunctiva is rarely reported. We report a case of Parry Romberg syndrome with characteristic clinical and radiographic presentation accompanied with rare ocular findings. The clinical features, radiological findings, and differential diagnoses to be considered, and the available treatment options are discussed in this report.

Perianeurysmal cysts are a rare and poorly understood finding in patients both with treated and untreated aneurysms. While the prior literature suggests that a minority of perianeurysmal cysts develop 1-4 years following endovascular aneurysm treatment, this updated review demonstrates that nearly half of perianeurysmal cysts were diagnosed following aneurysm coiling, with the other half diagnosed concurrently with an associated aneurysm prior to treatment. 64% of perianeurysmal cysts were surgically decompressed, with a 39% rate of recurrence requiring re-operation. We report a case of a 71-year-old woman who presented with vertigo and nausea and was found to have a 3.4 cm perianeurysmal cyst 20 years after initial endovascular coiling of a ruptured giant ophthalmic aneurysm. The cyst was treated with endoscopic fenestration followed by open fenestration upon recurrence. The case represents the longest latency from initial aneurysm treatment to cyst diagnosis reported in the literature and indicates that the diagnosis of perianeurysmal cyst should remain on the differential even decades after treatment. Based on a case discussion and updated literature review, this report highlights proposed etiologies of development and management strategies for a challenging lesion.
