Aim: To evaluate factors associated with the development of strabismus after cataract extraction and primary intraocular lens implantation. Methods: The medical records of 122 patients, aged 1.5mo to 9y, who had undergone cataract extraction with primary intraocular lens implantation between January 1993 and August 2011 were reviewed. Fourteen patients (17 eyes) with strabismus before cataract surgery were excluded. Patients were divided into those with congenital bilateral cataracts (64 patients, 128 eyes) and those with unilateral cataracts (44 patients, 44 eyes). The associations between the development of strabismus and age at cataract surgery, pre- and post-cataract extraction corrected distance visual acuity (CDVA), interocular CDVA difference, nystagmus, surgical method, and secondary cataract were evaluated. Results: Factors significantly associated with the development of strabismus included age at cataract surgery (≤1y), preoperative mean CDVA ≤20/100, presence of nystagmus in the bilateral cataract group and postoperative interocular CDVA difference >20/70 in the unilateral group. Postoperative CDVA ≤20/100 and preservation of posterior capsule, and presence of secondary cataract were significant factors in both groups. Conclusion: Children with congenital cataracts should be monitored carefully after cataract surgery for the development of strabismus, especially when they underwent surgery at age ≤1y, and they have nystagmus, large postoperative interocular CDVA difference, poor preoperative and postoperative CDVA, preservation of the posterior capsule, or secondary cataract.

Yellow clay dispersion has been applied to minimize fisheries impact by the red tide Cochlodinium polykrikoides blooms in Korean coasts since 1995. The present preliminary study documents the effect of yellow clay on Korean rockfish, Sebastes schlegelii, in terms of oxygen consumption rate (OCR). The OCR in the low clay suspension (0.05 and 0.23 %, w/w) showed normal level compared to the control. In contrast, the OCR for each one of three replicates in the high clay suspension (1.16 and 5.58 %, w/w) was not returned to the previous level that clay was not treated, indicating that high clay suspension (, w/w) might give negative effect on Korean rockfish. Overall, this result suggests that field application of clay to control Harmful Algal Blooms (HABs) may not give impact on Korean rockfish once the clay is dispersed in a low concentration (). In order to understand the changes of OCR in the repeated exposure to clay, it is required to do further studies on the changes of OCR when the fish is exposed to clay repeatedly after recovery in the normal seawater.

To evaluate factors influencing stereoacuity after surgery to correct unilateral developmental pediatric cataracts. We retrospectively surveyed 110 patients who had undergone removal of unilateral acquired developmental cataracts and primary posterior chamber intraocular lens implantation between February 1992 and December 2009. In all patients, stereoacuity was assessed using the Titmus test at the last follow-up period of minimum 2 years after surgery. Patients were divided into two groups according to the extent of stereoacuity: group 1 (n=42) had stereoacuity values≤100sec/arc and group 2 (n=68) values >100sec/arc. The values of ten parameters associated with stereoacuity were measured in each group: Cataract types, preoperative best corrected visual acuity (BCVA) of the affected eyes, preoperative inter-ocular difference of BCVA, age at cataract surgery, operative method, secondary cataract, postoperative strabismus, postoperative BCVA of the affected eyes, postoperative inter-ocular difference of BCVA, and anisometropia. The extent of stereoacuity was significantly associated with both operative method and secondary cataract (P=0.000 and P=0.016, respectively). All patients in whom the posterior capsule was preserved, had poor stereoacuity >100sec/arc. Significant correlations with the extent of stereoacuity were found with postoperative strabismus (P=0.048), postoperative BCVA of the affected eyes (P=0.002), anisometropia (P=0.034). : Postoperative stereoacuity was better in patients who underwent either optic capture or anterior vitrectomy after posterior continuous curvilinear capsulorhexis, and who didn't develop secondary cataracts or strabismus postoperatively. Furthermore, postoperative BCVA of the affected eyes, and anisometropia influenced the stereoacuity of the patients surgically treated for unilateral developmental pediatric cataracts.

The mudskipper Scartelaos gigas is expected to experience repeated severe hypoxia in its environment. Hence, we conducted experiments on the oxygen consumption rate (OCR) and OCR rhythm of S. gigas at low graded dissolved oxygen (DO) levels, without access to atmospheric air, to estimate its tolerance to hypoxia. A dominant circadian OCR rhythm was observed at the control DO level of 6.96–7.78 mg O2/l. This rhythm was unchanged until 2.06 mg O2/l, even though the amplitude of the peak was somewhat diminished at 2.06–2.87 mg O2/l. The OCR rhythm amplitude was greatly diminished and the rhythm period was also greatly changed at 1.23–2.05 mg O2/l. Nevertheless, the mean OCR (0.11 ml O2/g WW/h) at 1.23–2.05 mg O2/l was similar to that of control (0.12 ml O2/g WW/h). Thus, the weakness and period change of the OCR rhythm kept the metabolic rate level similar to control. These results suggest that S. gigas does not have normal metabolic activity at 1.23–2.05 mg O2/l but barely manages to endure this DO level as a pre-emergency state. This species could be inhibited under a longer maintenance period at DO level of 1.23–2.05 mg O2/l or still lower. It can be concluded that S. gigas is quite tolerant to low DO environment and may have a specific strategy for such tolerance.

We investigated the effects of temperature changes on the oxygen consumption rhythm in Japanese eels, Anguilla japonica, using an automatic intermittent flow respirometer (AIFR). The endogenous rhythm of the oxygen consumption rate (OCR) in the eels (n = 18; 44-74 cm, 145-690 g), freshly collected by bag net from estuaries, was nearly synchronous with the tidal pattern of the estuarine collection site. The magnitude of mean OCR (mOCR) of eels showed variable range of 82.2 - 116.5 ml under constant conditions. In case of increasing temperature from 25 to , the OCR of eels exhibited a gradually increasing trend with a rhythmic pattern until . Above the rhythms of the OCR dampened and the OCR decreased rapidly at around . The OCR of the eels exhibited the maximum value at , and then it sharply decreased. The results suggested that the critical thermal maximum (CTM) regarding the endogenous rhythms of the eels was at around when water temperature increased at /14 h following the acclimation at . In case of decreasing temperature (/14 h) from 25 to , the OCR of the eels displayed a abrupt decrease up to , and between at 23 and , there was an agitation which showed a slight increase in the OCR with a duration of 1-2 days. Below , the OCR rhythm of the eels showed a constant state regardless of temperature decreasing. These results suggest that the Japanese eel has an upper incipient lethal temperature at , with a lower thermal limit at . The biochemical aspects of the eels influenced by water temperature need to be further studied.

Purpose: To evaluate the safety and efficacy of transscleral intraocular lens fixation with preservation of the anterior vitreous in the treatment of ectopia lentis in patients with Marfan syndrome. Methods: Patients who had undergone surgical intervention for ectopia lentis with or without lenticular opacity were included. Best-corrected visual acuity before and after surgery was compared. Perioperative complications were evaluated. Results: A total of 23 patients (45 eyes) whose mean age at surgery was 16.9 ± 8.9 years were recruited. The mean follow-up period was 10.1 ± 5.8 months. Mean best-corrected visual acuity change (with respect to preoperative logarithm of the minimum angle of resolution value) was 1.03 ± 0.39. All patients showed >2 lines of improvement in visual acuity. Pupillary capture was found in 6 eyes. Medically controllable intraocular pressure elevation was noted in 12 eyes. Conclusion: Transscleral intraocular lens fixation with preservation of the anterior vitreous face is a safe and effective technique for treatment of ectopia lentis in patients with Marfan syndrome.

To evaluate the long-term therapeutic efficacy of phacoemulsification with intraocular lens (IOL) implantation in treating phacomorphic glaucoma. Ophthalmology Department, Maryknoll Hospital, Busan, Korea. This study evaluated eyes that had phacoemulsification with IOL implantation to treat phacomorphic glaucoma. Intraocular pressure (IOP), corrected distance visual acuity (CDVA), and anterior chamber depth (ACD) were measured preoperatively and postoperatively. The minimum follow-up was 48 months. The mean IOP in the 26 eyes was 49.0 mm Hg +/- 10.4 (SD) (range 31 to 70 mm Hg) preoperatively and 13.2 +/- 2.8 mm Hg (range 8 to 20 mm Hg) 48 months postoperatively (P<.0001, paired t test). No eye had increased IOP over the follow-up. The postoperative IOP was significantly lower 1 day postoperatively (P<.000, paired t test). The improvement in CDVA was statistically significant from 1 week postoperatively (P<.0001, paired t test). The CDVA improved postoperatively except in 1 eye with a preoperative acuity of no light perception. The CDVA was 20/50 or better in 16 eyes (61.5%). Preoperatively, the ACD was shallow (mean 1.5 +/- 0.3 mm) because of the swollen lens; the mean postoperative ACD was 2.6 +/- 0.1 mm; the increase was statistically significant. The mean preoperative ratio of lens thickness to axial length was 0.25 +/- 0.01, indicating a shallow ACD. In 1 eye, peripheral anterior synechias were seen on gonioscopy immediately after surgery; the eye required continuous postoperative medication for IOP control. Phacoemulsification with IOL implantation was effective in treating phacomorphic glaucoma.

... Ocular anomolies are a major problem, with the most common changes being microphthalmia and cataracts, presenting in 81%-90% of HSS patients [1,3] . The lenses may have been absorbed spontaneously after birth, which sometimes occurs in the setting of HSS [3][4][5][6] . Other ocular finding of HSS include microphthalmia (78%-83%), nystagmus (32%-45%), strabismus (33%-37%), blue sclera (22%-31%), sparse eyelashs and eyebrows (29%), fundus anomalies (18%-22%), conjunctival defects (11%), cornea abnormalities (9%-14%), down-slanting palpebral fissures (12%-13%) and so on [1] . ...

... Concerning complications, pupillary IOL capture was observed in one patient with MFS 1 day postoperatively, and the IOL was reposited followed by pilocarpine therapy without repeated captures. The pupillary capture rate was reported much higher in the pseudophakic eyes of patients with MFS (20)(21)(22) because the myopathy of pupil constrictors and dilators in this population gives rise to pliable iris and reverse pupillary block (23,24). To deal with this situation, preventative intraoperative surgical iridectomy (preferably with small gauge vitrectomy) or postoperative laser iridectomy are recommended (25). ...

... So, only having one strabismus in the bilateral group in this study is very good -2.6% compared to nearly 30% in David et al. [3]. The group that had unilateral lensectomy was also found to record a higher number of strabismus cases (29.5%) than the group that had bilateral lensectomy (17.2%) in a study conducted by Lee et al. [4]. Park et al recorded a high number of strabismus cases in a group of children with bilateral lensectomy, however, their study did not include unilateral lensectomy [6]. ...

... Additionally, the vision of glaucoma patients may be irreversibly degraded by at least 50% before their disease is diagnosed 9,10 . This disease can increase the original lens axial length thickness or radius to more than 2.6 mm, which damages the optic nerves, resulting in vision deterioration and blindness 11 . Similarly, Graves' ophthalmopathy results in physical changes, including eyelid lag or retraction related to the eye muscles, which can lead to exposure/dryness of the cornea 12,13 . ...
