BACKGROUND: A transcaruncular approach is typically used for reconstructions of medial wall fractures. However, others reported that a transconjunctival approach was conducive for securing an adequate surgical field of view. In this study, we aimed to examine the extent of repair of medial wall fracture via a transconjunctival approach. METHODS: We retrospectively reviewed the medical records of 50 patients diagnosed as having medial wall fracture via preoperative computed tomography and who underwent surgery between March 2011 and February 2014. The fracture location was defined by dividing each of the anterior-posterior and superior-inferior distances into three compartments. RESULTS: A transcaruncular approach was used in 7 patients, while the transconjunctival approach was performed in the remaining 43 patients. The transconjunctival approach enabled a relatively broad range of repair that partially included the front and back of the medial wall, and was successful in 86% of the entire study population. CONCLUSION: It is known that more than 50% of total cases of the medial wall fracture occur mainly in the middle-middle portion, a majority of which can be reconstructed via a transconjunctival approach. We used a transconjunctival approach in identifying the location of the fracture on image scans except for cases including the fracture of the superior portion in patients with medial wall fracture. If it is possible to identify the location of the fracture, a transconjunctival approach would be an useful method for the reconstruction in that it causes no damages to the lacrimal system and is useful in confirming the overall status of the floor.

Cataract surgery is the commonest ophthalmic surgical procedure and a local anaesthetic technique is usually preferred but the provision of anaesthesia in terms of skills and resources varies worldwide. Intraconal and extraconal blocks using needles are commonly used. The techniques are generally safe but although rare, serious sight- and life-threatening complications have occurred following the inappropriate placement of needles. Sub-Tenon's block was introduced as a safe alternative to needle techniques but complications have arisen following this block as well. Currently, there is no absolutely safe ophthalmic regional block. It is essential that those who are involved in the care of these patients have a thorough knowledge of the techniques used. This review article outlines the relevant anatomy, commonly used techniques and their safe performance and perioperative care.

BACKGROUNDSo far, most of the surgical techniques for congenital blepharophimosis syndrome are two-stage procedures. In this study, we investigated a modified one-stage procedure to reduce the suffering of patients.

METHODSFrom 2003 to 2005, we adopted an one-stage technique combining blepharoptosis correction with medial canthoplasty in 16 patients with congenital blepharophimosis syndrome (10 male, 6 female; aged from 6 to 21). All the patients had bilateral severe blepharoptosis, epicanthus inversus, and flat dorsum nasi. The movement of the upper lid was 0 to 3 mm, vertical length of the eye fissure 2 to 4 mm, horizontal length 13 to 22 mm, and the distance between the eyes was 35 to 39 mm. The patients were followed up for one half to 2 years after the operation.

RESULTSIn all the patients, after the operation, the horizontal length of the eyelid > 25 mm, the vertical length > 6 mm. and the distance between the eyes < 35 mm. The appearance of their double eyelids was satisfying.

CONCLUSIONThe modified one-stage technique combining blepharoptosis correction with medial canthoplasty can achieve favorable outcomes for patients with congenital blepharophimosis syndrome.

OBJECTIVETo discuss the effect of eye reconstruction with free flap.

METHODSFree flap was used in 21 patients of contracted eye socket and anophthalmos. The forearm free flap was utilized in 19 patients,the scapular flap in 2. Free flap with microvascular anastomoses was transferred into contracted eye socket. And hydroxyapatite implant was selectively inserted for intraorbital implantation according to the extent of contracted eye socket postoperation. Eye socket was reconstructed in one stage operation.

RESULTSThe flaps were transferred successfully in all patients. All patients were followed up between 4 to 42 months, better cosmetic results were achieved and well-fitted eye prosthesis was weaned.

CONCLUSIONFree flap is a useful alternative in treatment of severe contracted eye socket.

OBJECTIVE: To study surgical techniques and clinical applications of the intranasal endoscopic combined middle meatus and expand prelacrimal recess-maxillary ainus approach for orbital fracture treatment. METHOD: A retrospective clinical analysis of 3 patients whose admitted for orbital floor fractures or medial wall fractures operated by the intranasal endoscopic middle meatus with expand prelacrimal recess-maxillary ainus approach surgical treatment was studied, and the treatment effects and the postoperative complications were analyzed. RESULT: All patients had been followed up for 6 to 12 months. All cases of diplopia symptom were disappeared, enophthalmos were totally corrected, no cases of complication were found. CONCLUSION Endonasal endoscopic combined middle meatus and expand prelacrimal recess-maxillary ainus approach for orbital fracture treatment have great and clear view. This approach with less tissue damage and high therapeutic effect makes the cost lower than other methods and complications will be decreased as well, it has a great advantage in the orbital fracture treatment.

Strabismus fixus is very rare and the convergent form is rarely accompanied by blepharoptosis. We successfully treated one patient with high myopia whose convergent strabismus fixus, accompanied by blepharoptosis, became severe after cataract surgery. We report the case with a discussion of its pathology. We performed levator advancement operation, bilateral lateral rectus 11 mm resection, and bilateral medial rectus 8 mm recession. The suture was removed after maintaining temporary traction suture for 6 days. Blepharoptosis was completely corrected by postoperative 2 months. Esodeviation was 15PD, which was not increased compared with immediately after surgery. Satisfactory cosmetic outcome was obtained.

To standardize the corneal haze model in the resection depth and size for efficient corneal haze development, air assisted lamellar keratectomy was performed. The ex vivo porcine corneas were categorized into four groups depending on the trephined depth: 250 microm (G1), 375 microm (G2), 500 microm (G3) and 750 microm (G4). The stroma was equally ablated at the five measurement sites in all groups. Significant differences were observed between the trephined corneal depths for resection and ablated corneal thickness in G1 (p < 0.001). No significant differences were observed between the trephined corneal depth for resection and the ablated corneal thickness in G2, G3, and G4. The resection percentage was similar in all groups after microscopic imaging of corneal sections. Air assisted lamellar keratectomy (AK) and conventional keratectomy (CK) method were applied to six beagles, after which development of corneal haze was evaluated weekly until postoperative day 28. The occurrence of corneal haze in the AK group was significantly higher than that in the CK group beginning 14 days after surgery. Alpha-smooth muscle actin expression was significantly higher in the AK group (p < 0.001) than the CK group. Air assisted lamellar keratectomy was used to achieve the desired corneal thickness after resection and produce sufficient corneal haze.

This study was performed to assess the degree of acute pain in children following eye surgery using a Face Pain Rating Scale (FPRS), with a validity and reliability test employing a Numeric/Word Graphic Rating Scale (NWGRS). The degree of pain was obtained at 2, 4, 6, 8 and 24 hours after surgery using the FPRS and NWGRS. The changes in pain intensities were analyzed using a RM-ANOVA, while the relationship between the FPRS and NWGRS was analyzed by a Pearson coefficient in SPSS/WIN. Two third of the children experienced pain equal to, or greater, than moderate to severe, and about one fifth of the subjects expressed the most severe pain at 2 hours after surgery. At 4 hours after surgery, 95.3% of the children still complained of pain, and 8 hours after surgery, 82.8% of the patients experienced 'a little bit' or 'a little more' pain or discomforts. At 1 day after surgery, only 34.4% of children were free of pain. A high correlation between the FPRS and NWGRS was identified over 5 time-points (.887 < r < .735). The gender, type of the surgery and past operation experience had no effects on the degree of pain. Our results suggest that FPRS is a reliable and valid measurement for acute pain assessment in Korean children following eye surgery, and warrants application in the integrated clinical protocol, including non-pharmacological and pharmacological management of acute pediatric pain reduction following surgery.
